----y "Process and unit for univocal pairing of drugs corresponding to a prescribed treatment with a given patient".
* * *
The present invention relates to a process and a unit for univocal pairing of drugs corresponding to a prescribed 'treatment with a given patient.
The need is known of guaranteeing the safeness of operations Leading to the administration of drugs to hospitalized =, patients.
Analysed as a whole, this problem imposes the need of automating, in a closed circle, the steps of assigning, preparing and administering drugs to a given patient.
Among these steps the most dangerous is obviously the administration of the drug. In fact, whiCe any errors in the assignment and preparation can be remedied and reversed; this is obviously not true for the step of administration, wherein a safeness is required that is intrinsic and thus independent of the action of operators or of the patient himself.
Within this scope it is particularly important that the administration of the drug be preceded by a non-subjective verificat ion with the patient's data so as to avoid any possible error derived from a possible exchange of the drugs destined for different patients.
It is also important, even though within certain tolerances to be determined and defined on a case by case basis, to observe the hours of administration.
The existence of staff shifts in the hospital, in the absence of an adequate automated support structure, causes these requirements to be observed only with difficulty, especially at night.
The object of the present. invention is to accomplish a process and a unit which allow the avoidance of any possible error in administration, o~~serving the set hours, and to execute the updating of the case sheets to confirm that administration has taken place.
According to the invention such objects are attained with a process for the univacal. pairing of drugs corresponding to a given prescribed treatment with a given to patient, characterized in that i.t provides for assignment of identification data t:o eacr, individual patient, permanent association of said dat<~ to said patient through a support device that can be attached to the patient himself, prescription and writing irt~o a case sheet of a treatment for said patient, withdrawal and recognizing of a drug corresponding to the prescribed treatment, introduction of the withdrawn drug into a container previously marked w~_th identification data of the patient and of a drug administration to be performed, closure of said container, its transmission to a drug's delivery station, verification of the agreement between the data marked on the container and those of identification associated with the patient, opening of the contai.ner_ for extraction of t:he drug contained therein, verifying that it agrees with the treatment prescribed for the patient by reading said patient identification data c>n saie support device and drug's identification data and corr,paring them one with the other and with the prescribed treatment and, in case of agreement, issuing a signal to enable the administration of the drag to the patient.
More specifically, the present invention provides <~

Fig. 1 illustrates a machine for marking arm band devices for the support of the patients' identification data;
Fig. 2 illustrates a dolly machine for recording treatments and issuing signals to enable the administration of drugs;
Fig. 3 illustrates a machine for the preparation of drug containers.
With reference to Fig. 1, there is illustrated and indicated as a whole with 61 a machine for marking arm bands that can be attached to the body of patients, which, inside a machine casing 50 normally inaccessible from the outside, comprises a delivery station 1G wherein a magazine 1, for example in the shape of a cylindrical container, contains arm bands 2 arranged sequentially on a flexible suppart 3. Each arm band 2 is delivered on a corresponding support S, which forms part of a transfer device 4 suitable for causing the passage of the abovementioned arm band Z through stations for marking 6 and for verifying the markings 9.
The marking station 6 consists of a laser source 7 suitable for sending a modulated beam to a galvanometric head 8 in a position of displacing the laser beam in the plane perpendicular to the plane of the figure and tangential to the surface of the arm band 2 positioned at the marking station 6 to perform the arm band's indelible marking. Further details of the marking station are omitted, together with the indication of possible constructional variants thereof, referring for this to the detailed description contained in United States Patent 5,508,499 iApril 16, 1996) and filed in the name of the same applicant.
The station for verifying the markings 9 comprises in turn an optical transducer 10 consisting of a television camera, of a set of diodes or of an optical fibre heacl for returning the signal to an optical transducer positioned at a distance.
The machine 61 also comprises delivery 11 and rejection 12 stations, to which the arm band 2 is sent in case at the station for verifying the markings 9 the agreement between the marking as executed and the desired marking has been verified or otherwise, respectively.
For the running of the operation of the delivery stations 14, of the stations for marking 6 and of the stations for verifying the markings 9 the machine 61 is equipped with a control and data acquisition system 62, which comprises a computer 13 of the personal type and a reader of an identification tag 15, through which it is possible to obtain the patient's indication data, To the marking machine 6l there is also connected an admittance station 63, which comprises a computer 16 of the personal type connected to the computer 13 and to a central computer 17 of the operational type, as welC as to a reader of an identification tag 18 by means of which it is possible to introduce into the central computer 17 and into the computers 16 and 13 the patient's data obtained at admittance.
With reference to Fig. 2, there is shown a dolly machine 52 which comprises a computer 31 of the personal type, a bar code reader 32, a reader 35 of identification data stored on the arm band 2 of the patient and/or on a possible drug container, an electronic-key device 3b for opening said possible drug containers and a device 37 for erasing possible labels ;. ,,; ... ,...:. , ,.

_7_ associated with the abovementioned containers, possibly replaceable with a printer suitable for issuing documents to confirm that the administration of the drug has taken place.
With reference to Fig. 3, a machine for the preparation of S drug containers comprises, inside a machine casing 51 normally inaccessible from the outside, a container magazine 20, a delivery station 19 for the delivery of containers 28 from the magazine 20 to a support 21, which forms part of a transfer device 22 controlled by an external computer, which, fo-r example, can be the same computer 31 of the dolly machine 52 of Fig. 2.
It also comprises a writing and marking station 23 consisting of a laser source 24 which sends a modulated beam to a galvanometric head 25 for the deviation and the concentration of the Laser beam, which performs the indelible marking of a label on the container 28 with the identification data of the patient and of the corresponding desired drug administration, as indicated by the computer 31.
In succession to the writing and marking station 23 there is a verification station 33, which through an optical transducer 34 executes the verification of the agreement of the data marked on the label with the original information related to the patient and to the treatment assigned to the patient himself, stored in the computer 31.
There is then a rejection station 26 suitable for receiving the containers for which the abovementioned agreement has not been verified.
As an alternative to it, there are in succession stations for filling 27, closing 29, delivering 30 the container 28 suitable for receiving the latter in the case wherein the _8_ abovementioned agreement has been verified.
At the filling station 27 the containers 28 are filled with drugs aecarding to the treatment stored in the computer 31 after verifying the same by means of the bar code reader 32 connected to the computer 31, which reads the bar codes usually present on drug packages.
The computer 31 also drives the operation of the transfer device 22, of the laser source 24 and of the galvanometric head 25 of the marking station 23, of the optical transducer_34 of the verification station 33 and of the means for closing associated with the station 29.
With reference to the mentioned figures, initially the patient shows up at the admittance station 63 of Fig. 1, where he is identified by the appropriate staff, possibly by introducing his own identification tag into the reader 18. The corresponding identification data are stored in the central computer 17.
The marking machine 61 of Fig. 1 then delivers an arm band 2 destined to be attached to the patient for the identification of the patient himself on the occasion of every health-related event affecting him. In the absence of suitable equipment at the admittance station 63, the abovementioned operation can if necessary be carried out in an autonomous manner by the machine for marking and delivering the arm bands 61 of Fig. 1, possibly using for this purpose the reader 15 of identification tags in combination with the computer 31, The appropriate staff applies the arm band to the patient, which from that moment an shall be identified only by means of said arm band an the occasion of every health-related event affecting him.

_y_ Once the patient has been hospitalized with the corresponding arm band applied, the medical stafifi, after identification of the same through the arm band, prescribes a suitable treatment, consisting in the administration of given drugs at certain hours. Such treatment is stored in the computer 31 of the dolly machine 52 of Fig. 2.
With reference to Fig. 3, the computer 3'I of the abovementioned dally machine, or other suitable computer in which information corresponding to a given patient has =, previously been introduced together with the corresponding drug treatment, drives the operation of the machine for the preparation of the drug containers.
.In particular it drives the activation of the delivery station 19 fior the delivery ofi a container 28 from the magazine 20 on a support 21. In succession the computer 31 operates the transfer of the container 28 to the marking station 23 for the compilation of the label, executed by means of a laser beam originating from the source 24 and driven by the galvanometric head 2S.
The computer 31 then operates the passage of the container 28 through the verification station 33 where a verification is made on the agreement of the marking performed with the original information related to the treatment assigned to a given patient and stored in the same computer.
In the case where such agreement is not verified, the computer 31 operates the transfer of the container 28 to the rejection station 26. Otherwise, the container 28 passes to the filling station 27 to be filled with the drugs of the prescribed treatment, verified .through the bar code reader 32 connected to the computer 31, and then in succession to the closing station 29 and to the withdrawal station 30.
For the administration of the drugs the dolly machine illustrated in Fig. 2 is used once again, on which the containers 28 are periodically loaded and on which the computer 31 is also present.
On the display of the computer 31 there appear in temporal successian the different drug treatments with the corresponding intervals of tolerance of administration. When a given treatment is actually administered the appropriate staff verifies with the reader 35 the agreement of the identification data (for example, a suitable code such as that of the prior patent application No. 20907 Al90 dated 11 July 1990) present an the arm band of the patient under treatment with those present on the Label of the container 28. In the case wherein such agreement has been verified it proceeds with opening the container 28 and with remaving the corresponding label by means of the electronic-key device 36 and with the extraction of the drug contained therein. After reading the patient's identification data and the drug°s bar code by means of the readers 35 and 32, the computer 31 proceeds with verifying the agreement of said data and of the bar code with the treatment prescribed for that patient and then with the issue of a signal to enable the administration of the drug to the patient himself. Once administration has taken place, the Label is erased and it is subsequently paired with the case sheet of the patient under treatment. It should be noted that no administration takes place when the agreement between the information on the arm band 2 and that on the label of the container 28, as well as with the stored treatment, has not been verified.

At the filling station 27 the containers 28 are filled with drugs aecarding to the treatment stored in the computer 31 after verifying the same by means of the bar code reader 32 connected to the computer 31, which reads the bar codes usually present on drug packages.
The computer 31 also drives the operation of the transfer device 22, of the laser source 24 and of the galvanometric head 25 of the marking station 23, of the optical transducer_34 of the verification station 33 and of the means for closing associated with the station 29.
With reference to the mentioned figures, initially the patient shows up at the admittance station 63 of Fig. 1, where he is identified by the appropriate staff, possibly by introducing his own identification tag into the reader 18. The corresponding identification data are stored in the central computer 17.
The marking machine 61 of Fig. 1 then delivers an arm band 2 destined to be attached to the patient for the identification of the patient himself on the occasion of every health-related event affecting him. In the absence of suitable equipment at the admittance station 63, the abovementioned operation can if necessary be carried out in an autonomous manner by the machine for marking and delivering the arm bands 61 of Fig. 1, possibly using for this purpose the reader 15 of identification tags in combination with the computer 31, The appropriate staff applies the arm band to the patient, which from that moment an shall be identified only by means of said arm band an the occasion of every health-related event affecting him.
2'~~9~'~
_y_ Once the patient has been hospitalized with the corresponding arm band applied, the medical stafifi, after identification of the same through the arm band, prescribes a suitable treatment, consisting in the administration of given drugs at certain hours. Such treatment is stored in the computer 31 of the dolly machine 52 of Fig. 2.
With reference to Fig. 3, the computer 3'I of the abovementioned dally machine, or other suitable computer in which information corresponding to a given patient has =, previously been introduced together with the corresponding drug treatment, drives the operation of the machine for the preparation of the drug containers.
.In particular it drives the activation of the delivery station 19 fior the delivery ofi a container 28 from the magazine 20 on a support 21. In succession the computer 31 operates the transfer of the container 28 to the marking station 23 for the compilation of the label, executed by means of a laser beam originating from the source 24 and driven by the galvanometric head 2S.
The computer 31 then operates the passage of the container 28 through the verification station 33 where a verification is made on the agreement of the marking performed with the original information related to the treatment assigned to a given patient and stored in the same computer.
In the case where such agreement is not verified, the computer 31 operates the transfer of the container 28 to the rejection station 26. Otherwise, the container 28 passes to the filling station 27 to be filled with the drugs of the prescribed treatment, verified .through the bar code reader 32 connected to the computer 31, and then in succession to the closing station 29 and to the withdrawal station 30.
For the administration of the drugs the dolly machine illustrated in Fig. 2 is used once again, on which the containers 28 are periodically loaded and on which the computer 31 is also present.
On the display of the computer 31 there appear in temporal successian the different drug treatments with the corresponding intervals of tolerance of administration. When a given treatment is actually administered the appropriate staff verifies with the reader 35 the agreement of the identification data (for example, a suitable code such as that of the prior patent application No. 20907 Al90 dated 11 July 1990) present an the arm band of the patient under treatment with those present on the Label of the container 28. In the case wherein such agreement has been verified it proceeds with opening the container 28 and with remaving the corresponding label by means of the electronic-key device 36 and with the extraction of the drug contained therein. After reading the patient's identification data and the drug°s bar code by means of the readers 35 and 32, the computer 31 proceeds with verifying the agreement of said data and of the bar code with the treatment prescribed for that patient and then with the issue of a signal to enable the administration of the drug to the patient himself. Once administration has taken place, the Label is erased and it is subsequently paired with the case sheet of the patient under treatment. It should be noted that no administration takes place when the agreement between the information on the arm band 2 and that on the label of the container 28, as well as with the stored treatment, has not been verified.
