Abstract

An external automatic defibrillator including an attachment device that can be externally attached and carried by a patient, an identification device for detecting an abnormal event in the cardiac activity, which can be treated by an electric shock, as well as a defibrillator allowing to exert a shock upon the patient after having detected the abnormal event. In order to ensure reliable functioning over a longer period of time, the identification device is configured so that the identification device can detect an abnormal event in an interval of not more than 90 seconds or one minute.

Claims

1. An automatic external defibrillation device, having an attachment device for an external placement on and wear by a patient, having an identification arrangement for detecting an abnormal event in connection with a cardiac activity, which is treatable by an electric shock, and having a defibrillation arrangement for applying a shock to the patient after the abnormal event has been detected, the defibrillation device comprising:

the identification arrangement designed for detecting an abnormal event within a period of time of at most 90 seconds or one minute.

2. The defibrillation device in accordance with claim 1, wherein for the identification arrangement to send an identification signal to the defibrillation device within the period of time, the defibrillation device can automatically deliver a shock.

3. The defibrillation device in accordance with claim 2, wherein reference data are specified in the identification arrangement for identifying the abnormal event, and an evaluation arrangement detects the abnormal event from the patient data regarding cardiac activity supplied by the identification arrangement.

4. The defibrillation device in accordance with claim 3, wherein the reference data is provided in a patient-specific manner.

5. The defibrillation device in accordance with claim 4, wherein an additional sensor arrangement (42) makes available additional information regarding the patient and/or the operational state of the defibrillation device to the identification arrangement.

6. The defibrillation device in accordance with claim 5, wherein the additional sensor arrangement (42) has at least one movement sensor and/or at least one position sensor by which a movement or a position of the body can be detected.

7. The defibrillation device in accordance with claim 6, wherein the movement sensor and/or the position sensor has an acceleration sensor.

8. The defibrillation device in accordance with claim 7, wherein the additional sensor arrangement (42) has a strain gauge.

9. The defibrillation device in accordance with claim 8, wherein the additional sensor arrangement (42) has sensors for detecting a neurological state of the patient, sensors for detecting the blinking reflex, and/or sensors for detecting eye movement.

10. The defibrillation device in accordance with claim 9, wherein a voice output and/or voice input unit (15) for verbal information from or to a remote control station is provided, and the identification arrangement is designed for detecting and evaluating movements or movement patterns following a request for movement made to the patient, and/or for the evaluation of verbal signals from the patient.

11. The defibrillation device in accordance with claim 10, wherein the identification arrangement is designed to perform a calibration on a basis of a position and/or a movement state taken by the patient.

12. The defibrillation device in accordance with claim 11, wherein the identification arrangement is designed so that in defined positions of the patient a triggering of the shock is prioritized, or can only be triggered in defined positions.

13. The defibrillation device in accordance with claim 1, wherein reference data are specified in the identification arrangement for identifying the abnormal event, and an evaluation arrangement detects the abnormal event from the patient data regarding cardiac activity supplied by the identification arrangement.

14. The defibrillation device in accordance with claim 13, wherein the reference data is provided in a patient-specific manner.

15. The defibrillation device in accordance with claim 3, wherein an additional sensor arrangement (42) makes available additional information regarding the patient and/or the operational state of the defibrillation device to the identification arrangement.

16. The defibrillation device in accordance with claim 15, wherein the additional sensor arrangement (42) has at least one movement sensor and/or at least one position sensor by which a movement or a position of the body can be detected.

17. The defibrillation device in accordance with claim 16, wherein the movement sensor and/or the position sensor has an acceleration sensor.

18. The defibrillation device in accordance with claim 6, wherein the additional sensor arrangement (42) has a strain gauge.

19. The defibrillation device in accordance with claim 5, wherein the additional sensor arrangement (42) has sensors for detecting a neurological state of the patient, sensors for detecting the blinking reflex, and/or sensors for detecting eye movement.

20. The defibrillation device in accordance with claim 1, wherein a voice output and/or voice input unit (15) for verbal information from or to a remote control station is provided, and the identification arrangement is designed for detecting and evaluating movements or movement patterns following a request for movement made to the patient, and/or for the evaluation of verbal signals from the patient.

21. The defibrillation device in accordance with claim 20, wherein the identification arrangement is designed to perform a calibration on a basis of a position and/or a movement state taken by the patient.

22. The defibrillation device in accordance with claim 6, wherein the identification arrangement is designed so that in defined positions of the patient a triggering of the shock is prioritized, or can only be triggered in defined positions.
