Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Abgabe eines Notrufs, umfassend eine mobile Kommunikationseinheit, eine Positionserfassungseinrichtung und einen manuell betätigkaren Alarmschalter.The invention relates to a method and a device for dispensing a Emergency calls, comprising a mobile communication unit, a Position detection device and a manually operated alarm switch.

Derartige Vorrichtungen sind in jüngster Zeit für die verschiedensten Anwendungsgebiete bekannt geworden. Wesentlich begünstigt werden diese Entwicklungen durch sehr kleine und preisgünstige GPS-Empfänger, die eine verhältnismäßig genaue Lokalisierung ermöglichen. Dieser GPS-Empfänger wird dazu zusammen mit einer GSM-Einheit, die im Falle einer aufgrund der Umgebung bzw. Witterung erfolgenden Abschaffung des GPS-Signals die Ortung übernimmt, in einem Mobilfunktelefon integriert, über das im Notfall eine Alarmmeldung mit einer Positionsangabe an eine Zentrale gesendet wird. Dazu wird eine Notrufnummer gespeichert und einer bestimmten Notruftaste zugeordnet. Durch Betätigung dieser Notruftaste wird die Notrufnummer automatisch gewählt und die Positionsangabe an die Zentrale weitergeleitet. Je nach Anwendungsfall wird dann eine Kommunikationsverbindung aufgebaut oder aber die Zentrale leitet Einsatzkommandos wie Polizei oder Feuerwehr zum Ort des Notrufs. Bei einigen Anwendungsfällen, wie beispielsweise Seglern in Seenot ist die Betätigung der Notruftaste unkritisch, da diese meist körperlich noch wohlauf sind. Bei Personen mit einem hohen Gesundheitsrisiko wie Herzinfarktpatienten oder Schlaganfallpatienten können diese im Notfall derart von einem Anfall überrascht werden, daß diese keine Zeit mehr haben, einen Notruf abzusetzen.Such devices have recently been used for a wide variety of purposes Areas of application become known. These are significantly favored Developments through very small and inexpensive GPS receivers, the one enable relatively accurate localization. This GPS receiver is used together with a GSM unit, which in the case of a due to the Environment or weather conditions abolishing the GPS signal Locating takes over, integrated in a mobile phone, via the one in an emergency Alarm message with a position information is sent to a control center. To an emergency number is saved and a specific emergency button assigned. By pressing this emergency button, the emergency number becomes automatically selected and the position information forwarded to the head office. Each a communication connection is then established depending on the application or the head office directs commandos such as the police or fire brigade to the location of the emergency call. In some use cases, such as Sailors in distress are not critical to pressing the emergency button, as this is usually are still physically well. For people with a high health risk such as heart attack patients or stroke patients can do this in an emergency are so surprised by a seizure that they no longer have time, make an emergency call.

Der Erfindung liegt daher das technische Problem zugrunde, ein Verfahren und eine Vorrichtung zur Abgabe eines Notrufs zu schaffen, mittels derer auch Personen mit einer starken gesundheitlichen und/oder körperlichen Beeinträchtigung sicher und zuverlässig einen Notruf absetzen können.The invention is therefore based on the technical problem, a method and to create a device for making an emergency call, by means of which also People with a strong health and / or physical Can safely and reliably make an emergency call.

Die Lösung des Problems ergibt sich durch die Merkmale der Patentansprüche 1 und 8. Dabei ist der Notrufvorrichtung ein Sensor zugeordnet, der bestimmte Körperfunktionen erfaßt und die erfaßten Daten mit in einem Speicher abgelegten Referenzdaten vergleicht. Die Daten werden in einer Diagnoseeinheit miteinander verglichen und bei abnormen Abweichungen wird automatisch ein entsprechender Norruf abgesetzt. Dies ermöglicht insbesondere Personen mit einem hohen Gesundheitsrisiko, die jederzeit mit einem ohne schnelle Hilfeleistung für sie lebensgefährlichen Anfall rechnen müssen, eine erhöhte Mobilität, da diese auch ohne Begleitung beispielsweise Spaziergänge oder ähnliches unternehmen können. Die Notrufvorrichtung ist des weiteren für die häusliche Nachsorge nach Operationen oder für ein betreutes Wohnen von gebrechlichen Menschen geeignet. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution to the problem results from the features of the claims 1 and 8. The emergency call device is assigned a sensor that determines Body functions recorded and the recorded data with in a memory stored reference data is compared. The data is in a Diagnostic unit compared with each other and in the event of abnormal deviations a corresponding emergency call is automatically made. this makes possible especially people with a high health risk who are with at all times a life-threatening seizure without quick help increased mobility, as this is possible even without an escort, for example Can go for walks or the like. The emergency call device is further for aftercare after surgery or for a assisted living for frail people. More beneficial Embodiments of the invention result from the subclaims.

Der Sensor zur Erfassung von Körperfunktionen ist vorzugsweise als Lage-, Temperatur-, Puls-, Blutdruck-, Blutzucker-, Blutsauerstoffkonzentrations- und /oder Schweißsensor ausgebildet. Diese Sensoren sind bereits teilweise von Jogging- oder Fahrradcomputern bekannt, wo diese in Form eines Armbandes um das Handgelenk angelegt werden. Ein Schweißsensor läßt sich z.B. durch eine Messung des elektrischen Hautwiderstandes realisieren. Nichtinvasive Blutzuckersensoren auf optischer Basis sind bereits in der Erprobung, weisen jedoch für quantitative Messungen noch einige Probleme auf. Daher kann im Notfall auch auf die bekannten invasiven Sensoren zurückgegriffen werden. Ähnliches gilt für die Blutsauerstoffkonzentrations-Sensoren. Des weiteren können auch online EKG/EEG-Sensoren zur Anwendung kommen. Durch Kombination dieser Sensoren lassen sich bereits sehr viele verschiedene gesundheitlich bedenkliche Situationen erfassen.The sensor for detecting body functions is preferably a position, Temperature, pulse, blood pressure, blood sugar, blood oxygen concentration and / or Sweat sensor trained. These sensors are already partially from Jogging or bicycle computers are known, where they are in the form of a bracelet around the wrist. A welding sensor can e.g. by realize a measurement of the electrical skin resistance. Non-invasive Blood sugar sensors on an optical basis are already being tested however, some problems still arise for quantitative measurements. Therefore, in In an emergency, the well-known invasive sensors can also be used. The same applies to the blood oxygen concentration sensors. Furthermore ECG / EEG sensors can also be used online. By Combination of these sensors can already be very many different Record health-threatening situations.

Zur Erhöhung des Komfort und damit der Akzeptanz wird der Sensor als separate Einheit ausgebildet, die dann drahtlos, beispielsweise per Infrarot mit der Kommunikationseinheit kommunizieren kann.To increase comfort and thus acceptance, the sensor is used as formed separate unit, which is then wireless, for example by infrared the communication unit can communicate.

Um die Kommunikationsverbindung auch aufbauen zu können, falls die Kommunikationseinheit sich nicht unmittelbar bei der Person befindet, beispielsweise weil diese die Kommunikationseinheit bei einem Sturz verloren hat, ist die Empfindlichkeit von Mikrofon und Lautsprecher veränderbar.In order to be able to establish the communication connection if the Communication unit is not directly with the person, for example because they lost the communication unit in the event of a fall the sensitivity of the microphone and loudspeaker can be changed.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt ein schematisches Blockschaltbild einer Notrufvorrichtung.The invention is based on a preferred Embodiment explained in more detail. The only figure shows a schematic Block diagram of an emergency call device.

Die Notrufvorrichtung 1 umfaßt eine mobile Kommunikationseinheit 2, mit mindestens einem Sensor 3 zur Erfassung von Körperfunktionen, einen Speicher 4 mit Referenzdaten für die Körperfunktionen, eine Diagnoseeinheit 5, eine Sprach-Ein- und Ausgabeeinheit 6, eine Positionserfassungseinheit 7, einen Controller 8 und ein Interface 9.The emergency call device 1 comprises a mobile communication unit 2, with at least one sensor 3 for detecting body functions, one Memory 4 with reference data for body functions, a diagnostic unit 5, a voice input and output unit 6, a position detection unit 7, a controller 8 and an interface 9.

Die Notrufeinrichtung 1 wird individuell auf eine Person eingestellt. Hierzu werden vorab von der Person Gesundheitsdaten von einem Arzt erstellt und in dem Speicher 4 abgelegt. Dies können beispielsweise EKG-, Blutdruck- und Pulsdaten sein. Der Sensor 3, der vorzugsweise als Armband ausgebildet ist, erfaßt die zu den Referenzdaten entsprechenden aktuellen Gesundheitsdaten. Die durch den Sensor 3 erfaßten Daten werden in der Diagnoseeinheit 5 mit den Referenzdaten im Speicher 4 verglichen. Da aufgrund klimatischer Bedingungen oder körperlicher Anstrengungen die Meßdaten schwanken, muß dies in der Diagnoseeinheit 5 durch entsprechende Schwellenwerte berücksichtigt werden. Überschreitet jedoch die Differenz zwischen der erfaßten Daten und den Referenzdaten den oder die vorgegebenen Schwellenwerte, so kann auf einen akuten Notfall geschlossen und Alarm ausgelöst werden. Dazu werden dann die erfaßten Daten des Sensors 3 mit den aktuellen Positionsdaten der Positionserfassungseinheit 7 im Controller 8 aufbereitet und über das Interface 9 an die Kommunikationseinheit 2 übertragen, von wo diese an eine Zentrale übermittelt werden. Mit der Übermittlung an die Zentrale wird zwischen dieser und der Kommunikationseinheit 2 eine Kommunikationsverbindung aufgebaut. Über diese kann die Zentrale die in Not geratene Person nach weiteren Einzelheiten wie Befinden oder Aufenthaltsort befragen und die Person kann antworten. Die über die Sprach-Ein- und Ausgabeeinheit 6 eingegebenen akustischen Signale werden dazu im Controller 8 mit den anderen Daten gemischt und gemeinsam übertragen. Da die Kommunikationseinheit 2 vorzugsweise als handelsübliches Mobilfunktelefon ausgebildet ist, können das vorhandene Mikrofon und der Lautsprecher genutzt werden. Da jedoch nicht immer bei einem Unfall oder Anfall gewährleistet ist, daß die Person das Mobilfunktelefon in unmittelbarer Reichweite hat, kann eine separate Sprach-Ein- und Ausgabeeinheit 6 vorgesehen sein, die wie der Sensor 3 unmittelbar an der Person angeordnet ist. Eine weitere Möglichkeit besteht darin, die Empfindlichkeit des Mikrofons und des Lautsprechers zu erhöhen. Im einfachsten Fall geschieht dies automatisch bei jeder Alarmauslösung. Da dies jedoch eine normale Sprachübermittlung stören würde, wird die Empfindlichkeit vorzugsweise nur situationsbedingt verändert. Hierzu wiederum bieten sich zwei Möglichkeiten an. Entweder sendet die Zentrale ein die Empfindlichkeit veränderndes Steuersignal, falls keine akustischen Signale empfangen werden, oder aber das Mikrofon regelt sich selbst hoch, falls keine akustischen Signale aufgenommen werden. Dadurch kann, falls die Person nicht bewußtlos ist, ein Sprechkontakt aufrechterhalten werden, auch wenn die Kommunikationseinheit 2 sich nicht unmittelbar bei der Person befindet. Des weitern kann die Empfindlichkeit des Mikrofons derart erhöht werden, daß das Mikrofon wie ein Stethoskop beispielsweise Herztöne erfaßt.The emergency call device 1 is set individually for one person. For this the person's health data is created in advance by a doctor and in the memory 4 filed. This can include EKG, blood pressure and Pulse data. The sensor 3, which is preferably designed as a bracelet, records the current health data corresponding to the reference data. The data recorded by the sensor 3 are included in the diagnostic unit 5 compared to the reference data in the memory 4. Because due to climatic Conditions or physical exertion the measured data must fluctuate this in the diagnostic unit 5 by means of corresponding threshold values be taken into account. However, the difference between the recorded data and the reference data or the predetermined Thresholds, such as an acute emergency and alarm to be triggered. For this purpose, the acquired data from the sensor 3 are then used the current position data of the position detection unit 7 in the controller 8 processed and via the interface 9 to the communication unit 2 transmitted from where these are transmitted to a central office. With the Transmission to the headquarters is between this and the Communication unit 2 established a communication link. about the head office can provide the person in need with further details such as well-being or whereabouts and the person can answer. The acoustic signals input via the voice input and output unit 6 are mixed in the controller 8 with the other data and together transfer. Since the communication unit 2 is preferably a commercially available one Mobile phone is designed, the existing microphone and the Speakers can be used. However, since not always in an accident or Seizure ensures that the person uses the cell phone in the immediate vicinity Has a range, a separate voice input and output unit 6 be provided, which, like the sensor 3, is arranged directly on the person is. Another option is the sensitivity of the microphone and raise the speaker. In the simplest case, this happens automatically every time an alarm is triggered. However, since this is a normal one Would disrupt voice transmission, the sensitivity is preferably only changed depending on the situation. There are two options for this on. The control center either sends a change in sensitivity Control signal if no acoustic signals are received, or else the microphone regulates itself up if there are no acoustic signals be included. As a result, if the person is not unconscious, a Speech contact can be maintained even when the communication unit 2 is not directly with the person. Furthermore, the Sensitivity of the microphone can be increased so that the microphone like a For example, a stethoscope detects heart sounds.

Die Sensoren 3 zur Erfassung der Körperfunktionen sind vorzugsweise als nichtinvasive Sensoren 3 ausgebildet, was für die zu überwachende Person angenehmer ist. Dabei kommen vorzugsweise Druck-, Temperatur- und Lagesensoren, die als Unfall-Sensoren arbeiten, der Mikrosystemtechnik zur Anwendung. Zur Erfassung der Schweißabsonderung können neuartige chemische Sensoren oder Hautwiderstandsmessungen zum Einsatz kommen. Speziell für Diabetes-Patienten kann jedoch auch ein invasiver Sensor verwendet werden, der insbesondere bei einem Notfall die Blutzuckerkonzentration mißt und an die Zentrale überträgt, so daß diese bereits die entsprechenden Vorbereitungen treffen kann. Welche Sensoren 3 zum Einsatz kommen bzw. welche Körperfunktionen erfaßt werden, ist dabei stets individuell an die jeweiligen Risikofaktoren der Person anzupassen. The sensors 3 for detecting the body functions are preferably as formed non-invasive sensors 3, which for the person to be monitored is more pleasant. Pressure, temperature and Position sensors that work as accident sensors for microsystem technology Application. Novel methods can be used to record sweating chemical sensors or skin resistance measurements are used. However, an invasive sensor can also be used especially for diabetes patients be used, especially in an emergency Measures blood sugar concentration and transmits it to the control center, so that this can already make the appropriate preparations. Which sensors 3 are used or which bodily functions are recorded is included always adapt individually to the respective risk factors of the person.

Die Positionserfassungseinrichtung 7 ist vorzugsweise als GPS-Empfänger, GSM-Einheit bzw. auf Basis nachfolgender Mobilfunk-Standards und/oder als Peilsender ausgebildet. Die Positionserfassungseinheit 7 erfaßt periodisch die aktuelle Position der Person, die dann kontinuierlich in einen Speicher geschrieben und temporär gespeichert wird. Ist der Speicher voll, so werden sukszessive die ersten Positionsangaben überschrieben. Dazu kann der Speicher beispielsweise als Schieberegister ausgebildet sein. Alternativ kann auch ein RAM-Baustein zur Anwendung kommen, dessen selektierte Adresse kontinuierlich durch einen Zähler erhöht und bei Erreichen der letzten Adresse der Zähler erneut gestartet wird. Im Noffall wird dann der Speicherinhalt von der Kommunikationseinheit 2 an die Zentrale gesendet wird, so daß bei Ortungsschwierigkeiten im Notfall der zurückgelegte Weg rekonstruierbar ist. Zur Sicherheit kann der Speicherinhalt auch periodisch an die Zentrale gesendet werden, um bei einer Zerstörung der Vorrichtung oder anderen technischen Problemen Anhaltspunkte für den letzten Aufenthalt der Person zu haben. Gegebenenfalls können mit der periodisch gesendeten Positionsangabe auch die jeweils aktuell ermittelten Körperfunktionsdaten mitübertragen werden. Nach Absezuzng des Notrufs wird dann vorzugsweise der Peilsender aktiviert, um so den Rettungsmannschaften eine weitere Lokalisierungshilfe zur Verfügung zu stellen.The position detection device 7 is preferably a GPS receiver, GSM unit or based on the following mobile radio standards and / or as DF transmitter trained. The position detection unit 7 periodically detects the current position of the person, which is then continuously stored in a memory is written and saved temporarily. If the memory is full, then successively overwrite the first position information. In addition, the Memory can be designed for example as a shift register. Alternatively, you can a RAM block is also used, its selected address continuously increased by a counter and when the last address is reached the counter is started again. In the event of an emergency, the memory content of the communication unit 2 is sent to the center, so that at Location difficulties in an emergency the distance covered can be reconstructed. For security, the memory content can also be sent to the control center periodically sent to in the event of device destruction or other technical problems are indications of the person's last stay to have. If necessary, with the periodically sent position information the currently determined body function data are also transmitted. After the emergency call has been disconnected, the direction finder is then preferably activated, to provide rescue teams with additional localization assistance To make available.

Wie bereits ausgeführt, können der Sensor 3 und andere Komponenten als baulich separate Einheit zur Kommunikationseinheit 2 ausgebildet sein. In diesen Fällen findet vorzugsweise eine drahtlose Datenübertragung zum Controller 8 oder zum Interface 9 statt. Dies kann beispielsweise mittels Infrarot- oder HF-Übertragungen realisiert werden.As already stated, the sensor 3 and other components can be used as structurally separate unit to the communication unit 2 be formed. In In these cases, wireless data transmission preferably takes place Controller 8 or to interface 9 instead. This can be done using, for example Infrared or HF transmissions can be realized.

Der Speicher 4 für die Referenzdaten ist vorzugsweise als E- oder EE-PROM mit Sockel ausgebildet. Dies ermöglicht einerseits die Anpassung der Referenzdaten, falls diese sich im Laufe der Zeit verändern und andererseits die Nutzung der Notrufvorrichtung 1 durch verschiedene Personen, wobei dann einfach die Speicher 4 ausgetauscht werden.The memory 4 for the reference data is preferably an E- or EE-PROM trained with base. On the one hand, this enables the adjustment of the Reference data if it changes over time and on the other hand the use of the emergency call device 1 by different people, whereby then simply replace the memory 4.
