Description

The invention relates to a laboratory device and / or a medical device and a method for operating a laboratory device and / or a medical device according to the independent claims. Preferred developments are specified in the dependent claims.

Laboratory devices and / or medical devices have a diverse range of applications. In the present case, laboratory apparatuses are understood as meaning apparatus which can be used in a laboratory and which are used for carrying out chemical, biochemical, biological or microbiological processes, such as, for example, syntheses, sample preparation, sample preparation and analyzes. For the purposes of the invention, laboratory devices may, for example, be any type of sample dosing device, sample transport device, sample separation device, sample purification device, sample storage device, sample conversion device or sample analysis device. Concrete examples of laboratory equipment are: a fume hood, preferably a safety cabinet, a climatic chamber, preferably a laboratory heating or refrigerator or incubator (laboratory incubator), a laboratory oven, especially for the high temperature range, in particular a chamber furnace, a tube furnace, a A muffle furnace or an ashing furnace, a centrifuge, a mixing or shaking device, a water purification or treatment device (eg a water softening or desalination plant for the production of desalinated or ultrapure water or their parts such as ion exchangers, (reverse) osmosis devices, etc.). ), a pump or a flow meter for laboratory applications, a spectrometer (eg IR, NIR, FTIR, RAMAN, UV / VIS, NMR, atomic absorption, or atomic emission, ESR, laser, Mass spectrometer or other spectrometer), a chromatography device (GC, HPLC, LC and corresponding couplings with mass spectrometers), a filtration device, an electrophoresis device or a e Immunoassay analyzer.

In turn, instruments, apparatuses, devices or other objects which are used for therapeutic and / or diagnostic purposes are referred to as medical product (compare medical device law in Germany and EU Directive 93/42 EEC ). In some cases, one and the same device can be classified both as a laboratory device and as a medical device. Concrete examples of medical devices that can be used according to the invention are: Analysis devices for the examination of the human or animal body, in particular those for examination by means of radiation and / or sound, for example. For example, any type of X-ray or tomography device or other devices for examination of the body by means of ultrasound, laser radiation, etc., Equipment for the treatment of the human or animal body by means of radiation and / or sound such as laser or infrared radiation, ultrasound or the like, computer-aided surgical devices, Diagnostic monitoring and control devices, in particular for hospitals and care facilities, etc.

Generic laboratory equipment and / or medical devices (hereinafter collectively referred to as the device) are often used in shifts to allow optimal utilization of the device. Frequently, the shift times do not coincide with the operating intervals of the device, so that it is necessary that users of different layers give each other information about the device, for example about ongoing diagnosis or analysis processes, defects that may have occurred, used samples and / or substances with potential hazards , Reservierungswünsche etc. In practice, these are currently often used simply notes that provided with the appropriate message, then glued to the respective device. Such notes can easily fall off and / or be lost, so that a secure transfer of information is not guaranteed.

The object of the invention now lies in specifying a laboratory device and / or medical device that allows users of the device a simple and reliable way to transmit messages to subsequent users.

The object is achieved with a laboratory device and / or medical device and a method for operating a laboratory device and / or a medical device according to the independent claims. Preferred developments are specified in the dependent claims.

The basic idea of the invention consists in the fact that the device has a notification device that is designed to record, store and reproduce at least one voice message. This allows operators of the device to create, save and play a voice message directly to the device. Due to the fact that the notification device is part of the device, corresponding information can thus no longer be lost and is safely available. In addition, voice messages can be created much faster and more extensively in a short time than the usual written notes.

An essential feature of the notification device is thus in its pertinent embodiment that it is capable of recording acoustic voice messages. Specifically, she is thus able to send voice messages to an Device in a suitable manner record and store at least for a specified period. Accordingly, the notification device also includes, for example, a suitable device via which acoustic speech signals can be recorded, such as a microphone. The notification device must also be designed in such a way that it can also store the recorded voice message, ie keep it available for playback over a certain period of time. The storage is preferably carried out digitally, for example on a suitable memory device, such as a memory card, a memory chip (for example, compact flash, smart card, multimedia card, SD card / xD card, etc.). In principle, the methods and devices known in the prior art for recording and storing voice messages can be used.

Naturally, the notification device is also designed in such a way that it reproduces the recorded and stored voice message, for example at the request of an operator, acoustically perceptible to an operator of the device. For this purpose, it comprises, for example, a corresponding loudspeaker, in particular active loudspeaker, for reproducing the at least one stored voice message. Accordingly, the notification device can in particular be a digital audio recorder. In practical use, operators of different work shifts now have, for example, the option of leaving a message directly on the device via the corresponding notification device and making it available to the next shift for time-shifted playback. Due to the fact that the notification device is part of the device, the message is therefore also arranged captive on the device, so that a secure and reliable language assignment to the respective device is possible.

In order to ensure that a user is informed about a stored voice message and becomes aware of it, the notification device preferably has a display device. The essential task of the display device is to signal the operator the presence of a stored voice message. For this purpose, the display device may be designed in such a way that it preferably indicates acoustically and / or optically at least one stored voice message. In concrete terms, this can be, for example, an indicator light source, for example in the form of an LED, for an optical display device, and, for example, for a sound pointer, a regularly recurring advisory tone or the like. However, the display of the presence of a voice message succeeds particularly elegantly when the display device is a screen, in particular a liquid crystal screen, a thin-film transistor screen, a plasma screen or an OLED screen. By way of example, the status of the notification device, in particular the presence of a voice message, can then be displayed via this display screen. Such screens are often already present by default on known laboratory equipment and / or medical devices, so that an incorporation of a display device of a notification device according to the invention in these devices is particularly easy to implement.

Important for a flawless functionality of the notification device is that an operator is provided with the possibility of recording a voice message on the one hand and, on the other hand, reproducing it on request. Ideally, the notification device for this purpose comprises an input device via which the input of control commands for operating the notification device by an operator is possible. With the operation of controlling a recording function for a voice message and the triggering of the playback of a stored voice message is particularly referred to. The operation of the notification device may further include clearing at least one voice message, acknowledging playback of at least one voice message, forwarding and / or rewinding at least one voice message, skipping one or more voice messages, entering a user identifier, and / or a password; the additional triggering of lock functions, such as a reservation mode for the entire device, etc., include. Here it can now be provided that the input device of the notification device is formed voice controllable. Control commands can thus be communicated acoustically to the notification device in this case and are correspondingly recognized and processed by the input device. In principle, the measures known in the prior art for implementing voice control can be used here. The advantage of this embodiment is that the operator does not have to act manually to use the notification device. This can be particularly useful, for example, when voice messages are to be made on the notification device during an ongoing work process. However, it is simpler and often preferred in practical use if the input device of the notification device is designed to be at least partially manually operable. Control inputs can thus be performed by hand on the input device in this embodiment. Of course, also mixed forms of these two alternatives conceivable and encompassed by the invention.

In order to enable a convenient operation of the particular manually operable input device, this is preferably arranged accessible from the outside on the device. In concrete terms, this means that the notification device can be operated, for example, without prior commissioning of the device, in order to enable playback of the voice message, if possible, prior to use of the device. Of course, it can be provided that the input device has a separate protective cover or similar devices. This is particularly advantageous when the device is in a corrosive working environment and / or comes in any other way in contact with corrosive substances. If, for example, the device comprises a main housing, the input device is preferably arranged accessible from the outside of the housing. If, for example, a work space is provided in the device, such as, for example, in a working space of a safety work bench protected by a protective pane, the input device is preferably arranged outside this work space in order to enable the user to reproduce the voice message before accessing the work space.

In principle, the input device can have, for example, manually operable switches, such as a keyboard for operating the notification device. Preferably, however, the input device is a touch-sensitive screen, colloquially also referred to as a "touch screen". With regard to the construction and the mode of operation of the touch-sensitive screen, it is possible to make use of the screens known in the prior art in this connection. Under such a touch-sensitive screen or "touch screen" is thus concretely in particular a screen element with resistive, d. H. pressure-sensitive, surface-capacitive or inductive touch display surface understood. Such touch-sensitive screens have the advantage that they are commonly perceived by an operator to be very comfortable and, in addition, due to the clever menu navigation, they allow a particularly intuitive operation. In addition, can be dispensed with an additional, at least partially mechanically working keyboard, which saves space and also an aesthetically pleasing device design is possible.

Preferably, the notification device is designed in such a way that stores the at least one voice message linked to at least one additional information. If a plurality of voice messages can be stored, the notification device is also ideally designed in such a way that the same and / or different additional information can be assigned to several voice messages. Additional information refers to any information beyond the pure voice message to the respective voice message. Such additional information may be, for example, the creation time of the voice message, for example, to allow a temporal assignment of multiple voice messages. Additionally or alternatively, each voice message can also be assigned an individual expiration time. By this is meant, for example, a point in time at which the voice message is automatically deleted or marked as out of date. Additional information may also be a device function associated with the voice message, such as a device lock, etc., as will be described in more detail below. Such additional information also makes it possible to personalize the treatment of a voice message. This means, in particular, that pertinent additional information can be provided which provide for individual access authorization for interception and / or for processing and / or acknowledgment of the voice message. The voice message is thus assigned to one or more operators who can access the voice message for listening and / or for editing and / or for acknowledgment, while unauthorized operators are not allowed to do so. By editing is meant, for example, a deletion of the voice message and / or a supplement to the contents of the voice message and / or an extension of a decay time, etc. Acknowledgment of a voice message signifies a confirmation that the voice message has been intercepted. In concrete terms, this may for example consist of the input of an acknowledgment code or of the input of a user identifier etc. required before or after the playback of the voice message. The combination of the voice message with one or more of the above additional information makes possible overall an even more efficient processing of corresponding voice messages that is standardized under quality assurance and management aspects.

However, it is not only possible to link the individual voice message with further additional information as described above. Another development of the invention also provides that it is possible to design the notification device in such a way that different device functions and / or device applications can each be assigned an individual voice message. This embodiment is thus characterized by the fact that here a linkage of a voice message with a device function and / or device application is made. This can be, for example, a warning that is automatically reproduced in the performance of a specific function of the device and / or the operation of the device in a border area, etc. Such warnings are previously predefined ex factory and deposited in the device control immutable. However, the present invention now allows individual design and adaptation of these voice messages to the needs of the user or the respective user. It goes without saying that then corresponding sensors or similar devices must be present in the device to ensure the playback of the respective voice message when performing the device function and / or device application at the desired time. An example of such an individual voice message for a device function and / or device application is the reproduction of a clue for cleaning the hands when a device is switched on, the indication of due maintenance work, the indication of a device defect etc. Situations are also conceivable for ongoing work processes. in which playing a stored voice message is useful and helpful. If, for example, a centrifuge process is attempted to prematurely open the lid of a centrifuge, ie while the rotor is still rotating, an indication to the operator that the rotor of the centrifuge has not yet come to a standstill can be issued with appropriate detection of an opening attempt. Of course, a multiplicity of further corresponding situations is conceivable here and encompassed by the invention.

Depending on the field of application of the device, it may be necessary to ensure for reasons of safety that only authorized operators have access to the device or the voice message. In particular for these cases, it is now provided that the device comprises an input device for inputting an identification code, a device for voice identification and / or for face recognition, wherein the notification device is designed in such a way that the input device and / or the device for voice identification and / or or face recognition blocks or releases the playback of the at least one voice message. Here is the playback of the voice message thus a security function, specifically a voice identification and / or a face recognition, upstream, which serves as proof of the access authorization of the operator. In this case, either an identified authorization or a determined non-existent authorization can lead to the reproduction of the voice message. This basic principle can be extended to all functions related to the notification device, such as a determination of the authorization for receiving and / or processing the voice message, etc.

In order to ensure that the operator of a device really listens to a stored voice message, it may be provided that the device comprises a motion sensor which is designed in such a way that upon detection of a movement in the space monitored by the motion sensor, at least one event is triggered becomes. In the present case, such an event may in particular be the automatic reproduction of the at least one voice message or at least the activation of an indication of the stored voice message, such as the activation of an optical information device, in particular a display illumination, and / or the triggering of a signal tone and / or alternative acoustic hint. All events thus have in common that they point more or less comprehensively to the at least one stored voice message automatically due to a detected movement in the area monitored by the motion sensor. If only one signal tone and / or alternative acoustic indication, such as an automatically reproduced voice message with the indication that a voice message is deposited, triggered, then still an active operation of the notification device by the operator is required. The same applies to the switching on of an optical information device, such as a flashing light, the aforementioned display illumination and / or, for example, the display of a corresponding icon in a display screen. The most reliable is obviously the automatic reproduction of the at least one voice message when a movement is detected in the room monitored by the motion sensor. The present development of the invention with motion sensor is now particularly suitable for such devices that allow the determination of a meaningful monitoring area by the motion sensor. The monitoring area is thus the space within which the motion sensor can detect a movement. This may, depending on the design and arrangement of the motion sensor, in particular, for example, the working space of a safety workbench and / or the interior of a centrifuge or the like. The monitored space should always be chosen so that a reproduction of the at least one voice message is excluded, for example, only by accident on the device passing people, so basically an interior monitoring or monitoring only the lying in the vicinity of the device space by the motion sensor is preferred.

It is also possible to design the device in such a way that the notification device is hierarchically superior to a function of the device. For this purpose, it is provided that the device has a device control connected to the notification device. The device control functionally establishes the link between the notification device and the device-controlled function of the device. The device control is now designed in such a way that it controls at least one function of the device controlled by it as a function of the notification device. In other words, this means that the implementation of this function of the device by the device control ultimately depends on an operating state of the notification device. This may in practice mean that the implementation of this function of the device by the device control, for example, will be allowed only when a stored in the notification device voice message has been played. Thus, for example, an active blocking ("blocking function") of certain device functions can be provided by the device control until a stored voice message has been reproduced and preferably also acknowledged by the operator. This ensures that a potentially stored voice message is intercepted and perceived by the operator in good time before carrying out this particular function. In a specific embodiment, this may mean, for example, that the start of a centrifuging process by pressing a start button is only possible when a potentially stored in the notification device voice message has been reproduced. The same is for the opening of covers of the device, for example, the opening of a centrifuge lid, pushing on the protective screen of a safety cabinet, opening the cabinet door of an incubator, etc. possible. Here, the device control locks using the blocking function thus, for example, a closed lid or a protective screen until the playback of the voice message. In these cases, it can then be ensured, for example, that an operator is informed by timely listening to a deposited voice message for contained dangerous substances or the like. In these embodiments, the device control thus comprises a blocking function, the release of which takes place only after the at least one voice message has been reproduced by the notification device. The blocking function of the device control is thus distinguished by the fact that it blocks at least one function of the device until the device control releases this function after the at least one voice message has been reproduced by the notification device.

Basically, any device may be formed according to the above embodiments, for which the transmission of voice messages between multiple operators is desired. In practical use, it has been found that the invention is particularly suitable for the following devices: a sample treatment device and / or analysis device, for example a fume hood, preferably a safety workbench, a climatic chamber, preferably a laboratory heating or refrigerator or an incubator, a centrifuge, a mixing or shaking device, a water purification or treatment device, a pump or flow meter for laboratory applications, a spectrometer, a chromatography device, a filtration device, an electrophoresis device, an immunoassay analyzer or a laboratory oven. Such devices are known per se in the prior art and, according to the invention, are particularly suitable for further development with a notification device according to the invention.

The invention also relates to a method for operating a laboratory device and / or a medical device, in particular such a laboratory device and / or medical device, as has been described above. Again, the term "device" is used below for laboratory equipment and medical devices. Essential steps of the method according to the invention are on the one hand according to step a) recording a voice message with a notification device of the device and on the other hand according to step b) reproducing the voice message on demand by an operator or by entering a specified event to reproduce the voice message. It is therefore crucial that first a voice message is recorded and stored directly on the device via the notification device of the device. Thus, the voice message is directly associated with the device and can not be lost, for example, like a slip of paper. In the second step, the notification of the stored voice message takes place at the example temporally subsequent operator. This is done either actively on request by the operator or passively by the occurrence of a specified event to reproduce the voice message, such as, for example, according to the following statements the operation of a motion sensor or the triggering of a particular device function.

In order to ensure as far as possible that a stored voice message is actually intercepted, it is preferred if the presence of a deposited voice message is indicated by a corresponding display after the recording of the voice message. For this purpose, it can be provided, for example, that an acoustic and / or optical signal via a suitable signaling device, such as an indicator light, a signal tone, the insertion of a corresponding symbol in the display area a display screen, etc., takes place. This makes the operator very reliably aware that a voice message is stored for listening.

The implementation of the method according to the invention succeeds particularly well if the display of the availability of a voice message after step a) and / or the reproduction of the voice message according to step b) takes place automatically by the occurrence of a specific event. According to the invention, such an event can be, in particular, the triggering of a motion sensor and / or the performance of face recognition and / or the input of a code, for example manually via an input keyboard and / or by voice recognition, etc. It may be provided that the proof of an authorization and / or the lack of proof of an authorization is the event for carrying out the steps a) and / or b). In this way, the sequence of the method according to the invention can be automated on the one hand and also personalized on the other hand. Of course, several events can also be combined for steps a) and / or b).

Ideally, when the method is carried out, it is also possible, with the recording of the voice message according to step a), to store the voice message with at least one additional information and in particular a plurality of additional information. Additional information supplements the pure voice message with additional aspects. For this purpose, reference is additionally made to the above comments on the device. Specifically, it can be, for example, the creation time of the voice message, so that a temporal assignment of one and in particular multiple voice messages is also possible in retrospect. Additionally or alternatively, the recorded voice message may be further assigned a creator identity. It is then possible to determine exactly which voice message goes back to which operator. In a similar way, it is also possible to assign the recipient identity of the intercepted voice message. It is then possible to determine exactly which operators have intercepted the respective voice message. This can be linked, for example, with the input of a user code, a face recognition and / or a voice recognition. It is also possible to set the validity period of a voice message, whereby, for example, after the expiration of the validity period, an automatic deletion of the voice message is provided. In this way, it can be prevented that an excessive number of voice messages is stored uncontrolled in the memory of the notification device. An interception authorization can also be stored with the voice message as additional information. It is then possible that only a limited, authorized group of people listening to, changing, deleting and / or acknowledging a voice message is possible. All these functions have in common that in the end result with the voice message itself additional information, be it when creating and / or listening to and / or otherwise treating the voice message, linked.

The implementation of the method according to the invention succeeds particularly well if, with the recording of the voice message according to step a), an event is defined for, in particular automatic, reproduction of the voice message. Accordingly, it is then provided that the reproduction of the voice message takes place when the event occurs. Such events may include identifying the user's identity, entering a sharing code, identifying a voice, or similar personalized events. In addition or as an alternative, it may also be device-dependent events, such as the switching on and off of a device, the opening and / or closing of a device closure and / or a device cover or other device functions. Essential in this alternative method is that it is provided in particular that the reproduction of the voice message when the event occurs automatically or automatically without further active action of the operator. In this way, it is particularly well ensured that the operator also perceives the content of the deposited voice message.

Identical and identical components are denoted by the same reference numerals in the figures, wherein not every repetitive component is necessarily designated in each figure.

1a shows the essential basic structure of a laboratory device according to the invention and / or medical device (hereinafter referred to as device 1 designated). The device 1 includes next to a housing 2 as an essential element for the invention, a notification device 3 , This is in the present embodiment, at least with their in 1a visible operating device 4 on the outside of the case 2 can be arranged and thus externally by an operator of the device 1 directly reached and operated. A schematic basic structure of this notification device 3 is in 1b illustrated by way of example. In addition to a display screen designed as a touchscreen 5 (Display device), thus simultaneously as an input device 4 acts is a control unit 6 , a microphone 7 , a speaker 8th , a store 9 as well as a power supply 10 available. Operation of the notification device 3 , in particular with regard to the recording and reproduction of voice messages, takes place via the display screen 5 on which suitable menu guides are displayed. About microphone 7 Acoustic voice messages may be recorded by an operator and, after appropriate processing in the control unit 6 , In the storage room 9 be deposited. To retrieve the stored voice message can also be a corresponding operation on the display screen 5 and the voice message is audibly audible through the loudspeaker 8th be issued. The memory 9 is a data storage, in particular, for example, a memory card, a flash memory, a hard disk, etc. It is essential that the memory 9 at least for the transitional deposit and storage by the notification device 3 recorded voice messages is formed. The notification device 3 further includes a power supply 10 , which is, for example, a power connection to the power network of the device 1 can act. However, it is also possible and included by the invention that the power supply 10 at least also has a battery to an operation of the notification device regardless of an applied power supply of the device 1 to enable. About the display screen 5 In addition, the presence of one or more stored voice messages can be displayed, so that an operator in this case is visually pointed to a stored voice message. Overall, the device stands out 1 thus in particular the fact that directly on the device 1 Even voice messages can be stored, so that, for example, several operators of a lab-operated laboratory in a simple and reliable manner of each other and whatever kind and on the device 1 can convey related voice messages. The sticking of slips or comparable error-prone solutions can thus be dispensed with.

In 2 is an example of a concrete training of a device 1 a laboratory device in the form of a safety cabinet 11 specified. Such safety workbenches are known per se in the prior art and for example in the DE 10 2011 114 993 A1 described, which is incorporated herein by reference. The safety workbench 11 has a work space enclosed by a housing 12 on top of a sliding windshield 13 is accessible to a user, for example, to process samples in, store, etc. About at eye level of a standing operator above the workspace 12 is as an input device 4 trained display screen 5 a notification device 3 , as in the example 1a and 1b has been described in more detail, taken in. If an operator steps on the safety workbench 11 approach, his attention almost inevitably on the display screen 5 directed. There he is informed about the presence of one or more stored voice messages and / or can even by appropriate operator inputs on the control 4 to record voice messages.

3a shows another example of a device according to the invention 1 using the example of a laboratory device 1 in the form of a laboratory centrifuge 14 , Such a laboratory centrifuge is known from its basic structure, such as in the DE 10 2011 100 044 A1 which is also incorporated herein by reference. The laboratory centrifuge also has a housing 2 on, but in the present case upwards from a lid 15 is closed. Im in 3 unrecognizable inner working space is stored in a known manner, a rotor for centrifuging samples. Operation of the laboratory centrifuge 14 via an input device 4 comprising, in particular, a display screen embodied as a touch-sensitive screen 5 , The display screen 5 thus also acts simultaneously as an input device 4 , The other elements of in 1b notified device 3 are in the input device 4 and / or inside the housing 2 the laboratory centrifuge 14 arranged.

As another device 1 is in 3b an incubator 37 specified. This comprises in the present embodiment, a cabinet-like housing 2 whose interior is from a forward-opening door 39 is closable. Above the door 39 is a control module 40 arranged in the unspecified display and control devices are arranged with which the operating parameters of the incubator 37 , in particular temperature, humidity and, if appropriate, further parameters relevant for incubators, are adjustable and / or displayable. Further, in the control module 40 a display screen 5 with input device 4 as part of the notification facility 3 out 1 available. On the function and structure of the notification device 3 Reference will be made to the foregoing and following statements. It is also possible, at least the display screen 5 in the door 39 , preferably at eye level of an operator to arrange, for example, when opening the door to improve the perception of the display of a stored voice message.

As a further concrete embodiment of a device 1 is in 3c finally a laboratory oven 38 specified. Also the laboratory oven 38 includes a housing 2 and a door swung open here 39 , The door 39 closes a furnace interior 40 , which is used for example as an ashing and / or Glühzwecken. Below the oven door 39 is also here as part of the notification facility 3 out 1 a display screen 5 with input device 4 available. This allows different operators of the laboratory furnace 38 easy and reliable voice messages directly to the laboratory oven 38 deposit in a secure manner.

The 4a . 4b and 4c relate to alternative embodiments of a device 1 , for example, the devices of 2 and 3a to 3c , with different operating functions. Essential for the embodiments according to 4a . 4b and 4c is that the functional elements described therein each have a sensor for monitoring, in the manner with the control unit 6 the notification device 3 is connected, that upon detection of a corresponding triggering event of the sensor one in the memory 9 the notification device 3 stored voice message automatically via the speaker 8th is issued. According to the embodiment 4a is additionally an on / off button 17 available. Its positioning in the closed position and / or switch-off position is determined by a position sensor 18 monitored and sent to the control unit 9 the notification device 3 transmitted. The control unit 6 the notification device 3 is now formed in the present embodiment in such a way that when switching on or moving the on / off switch from its off position to the on position an optionally existing, in the memory 9 stored voice message is played back automatically. An operator of the device 1 In operation, therefore automatically hears the stored voice message. Alternatively, in the embodiment according to the 4a also be provided that in case of pressing the on / off switch 17 a standard text is displayed, which indicates a stored voice message, and / or any other acoustic and / or visual indication to the operator.

Similarly, the embodiment according to 4b , There is a process sensor 19 indicated for monitoring a working process of the device 1 , For example, the execution of an analysis process, a cleaning procedure or the like is formed. The process sensor 19 is with the notification device 3 connected so that these are determined by the process sensor 19 determined operating conditions corresponding voice messages, automatically or on request by the operator, outputs. The device indicated in FIG 1 has as complementary or alternative development also a swing-up lid 15 on, for example, how he is in the 3 has already been described. The device 1 out 4b includes a cover closure sensor 20 , which is designed in such a way that it determines whether the lid 15 swung open (as in 4b indicated) or in its closed position (for example according to 3 ). Also the lid closure sensor 20 is with the notification device 3 connected and thus transmits this the closure state of the lid 15 , The control unit 6 the notification device 3 is now designed in such a way that they have a potential in memory 9 then stored voice message automatically via the speaker 8th audibly reproduced by an operator when the lid 15 For example, it opens from its closed position. It can then, for example, on the sample content of the device 1 or similar information.

The embodiment according to 4c has a motion sensor 21 on, a fixed surveillance space 22 , which is formed like a club in the present embodiment, monitored to see whether there are movements or not. The motion sensor 21 is also with the notification facility 3 connected. The control unit 6 of the device 1 according to 4c is now designed in such a way that one in memory 9 stored voice message then acoustically over the speaker 8th is played when the motion sensor 21 a movement in the surveillance room 22 determines, for example, by a the device itself 1 approximate operator. Thus, once an operator to the device 1 approaches, the deposited voice message is automatically played in this embodiment and the operator pointed to the message content.

In an alternative embodiment, the reference numeral 21 also be called a recording device for facial recognition. With the device 21 can then, depending on the embodiment, taken an image of the face of an operator and then evaluated by 2D or 3D method. Additionally or alternatively, also via the microphone 7 the notification device 3 (Embodiment according to 1b ) the voice of the operator recorded and the voice recognition by the notification device 3 be used.

The 5a and 5b give different situation views of the touch-sensitive display screen 5 trained operating element or the input device 4 again, as has been indicated for example in previous embodiments. 5a relates to an example of a recording and playback mode. The buttons 23a to 23c correspond to different functions. With the button 23a The recording mode can be started, in which the recording of voice messages via the microphone 7 is possible. The button 23b corresponds to a stop button, via which the recording of a voice message or the playback of a voice message can be stopped. The button 23c Finally, there is a playback function that can be used to play saved voice messages. Of course, other buttons, such as fast forward and rewind, skip, delete, acknowledge, etc., may be present. The display field 24 indicates to the operator that he is currently in the usage menu for recording and playing back voice messages. 5b clarifies the display in the display screen 5 if several voice messages are stored. That at least one voice message is stored, for example, by the solid lines in the display panel 24 played. Alternatively or additionally, in this case, this symbol can also be greatly enlarged or displayed as modified. In the display field 25 the number, in this case two, stored voice messages is specified. Additionally or alternatively, further information can be displayed, such as the recording date, the length of the voice message, the recipient identity, the validity period of the respective voice message, etc.

6 Finally, illustrates the essential steps of various alternatives for carrying out the method according to the invention.

Core elements of the method for operating a device, in particular in one of the embodiments according to the preceding embodiments, are a) the recording 30 a voice message with a notification device of the device and b) according to step 31 playing the voice message on demand by an operator or by entering a specified event to play the voice message. This represents the simplest embodiment A of the method according to the invention, wherein a multiplicity of further modification possibilities can be provided in order to widen the functional range of the method according to the invention. The inventive method thus makes it possible to create voice messages on site directly on the device and time-shifted, for example, to another operator, play.

Particularly important here is a pertinent further training that after recording 30 a message to the voice message 32 via the presence of a stored voice message. This can be done, for example, optically and / or acoustically. In this way, an indication to the operator that a voice message is deposited.

Neither displaying the availability of a voice message according to step 30 nor playing the voice message according to step 31 must, however, be permanent and / or by separate manual triggering. Additionally or alternatively, the display of the availability of a voice message and / or the playback of the voice message by another event according to step 33 to be triggered. This can be in particular the triggering of a motion sensor, the performance of a face recognition with a corresponding positive or, depending on the content of the voice message, negative identification and / or entering and identifying a code.

In the further process alternative B it is according to step 34 also provided that the recording of the voice message according to step 30 with the saving of additional information, in particular, for example, the creation time of the voice message and / or the creator identity and / or the recipient identity and / or the validity period of the voice message occurs. In this way it is possible to considerably expand the information content of the pure voice message or the management of the voice messages of the notification device 3 efficient. Thus, it can also be provided, in particular, that the voice message is automatically deleted after the specified validity period has expired. Of course, this method alternative can also be used in particular with the steps 32 and or 33 be supplemented.

However, such additional information can also be, for example, a so-called blocking function. In the present case, this means that certain functions of the device, for example switching on / off, carrying out maintenance operations, opening and closing covers or other covers, device reservation, etc., can be linked to a voice message. Then, for example, in certain activities on the device, an operator can be notified by playing the respective voice message that, for example, a work process is running and should not be interrupted, the device is reserved for a certain period of time, the device has a defect, etc. Disabling function thus means that by the control unit of the notification device 3 certain device functions are actively disabled and the operator is informed by the corresponding voice message about this state, its cause, the responsible operator, etc.

It can also be provided according to the further method alternative C that with the recording of the voice message according to step 30 an event is set to play the voice message, as in step 35 specified. It is then envisaged that the voice message is automatically sent at the occurrence of the event according to step 36 is reproduced. This may include, for example, the course of a particular work process, at the end of the playback of the voice message is provided, for example, the completion of an automated cleaning process, a disinfection routine, etc. Additionally or alternatively, for example, defect situations can be defined as possible events for playback of individually defined voice messages. Overall, this is a high degree of customization of the operation of the device 1 possible, so that the inventive method in this alternative embodiment allows a maximum of customization options to the working environment of each user. Of course, this alternative process can also be achieved through the steps 32 . 33 and or 34 be supplemented.
