Abstract

Heart defibrillator comprising a high-voltage power supply, a storage capacitor, and at least two electrodes, and at least one contactless biometric sensor. Since the biometric sensor does not need to be in contact with the skin of the patient, it maintains its sensing capabilities even through any regular clothing between the sensor and the body of which one or several biometric signal are to be measured. Therefore, an initial assessment of the health state of a patient can be quickly obtained. The high-voltage power supply, the storage capacitor and the at least two electrodes are used for producing an electrical pulse and applying said pulse to a patient.

Claims

1. Heart defibrillator comprising a high-voltage power supply, a storage capacitor, and at least two electrodes, characterized in that it further comprises at least one contactless biometric sensor.

2. Heart defibrillator according to claim 1, further comprising analyzing means connectable to said biometric sensor.

3. Heart defibrillator according to claim 1 or 2, wherein said contactless biometric sensor is a capacitive sensor.

4. Heart defibrillator according to claims 1 to 3, wherein said contactless biometric sensor is comprised in said electrodes.

5. Heart defibrillator according to claims 1 to 4, further comprising decoupling means to decouple said biometric sensor while said storage capacitor is decharged through said electrodes.

6. Heart defibrillator according to claims 1 to 5, further comprising shielding means for said contactless sensor adapted to eliminate or reduce interference by the proximity of other persons while a measurement using said contactless sensor is performed.

7. Heart defibrillator according to claim 6, wherein said shielding means comprise a conductive layer disposed on the backside of said contactless sensor and connected to ground.

8. Heart defibrillator according to claims 1 to 7, wherein said electrodes comprise adhesives adapted to fix said electrodes on the skin of a patient and wherein said adhesives are covered by a peelable protective film providing for non-contact measurement by means of said electrodes during measurement using said biometric sensor to determine if said patient requires defibrillating intervention.

9. Heart defibrillator according to any one of claims 1 to 8, wherein said at least one biometric sensor is part of an electrocardiographic device, integrated with said heart defibrillator.

10. Method for an automatic external defibrillator, having a high-voltage power supply, a storage capacitor, at least two electrodes and at least one contactless biometric sensor, said method comprising:

performing an initial biometric measurement by means of said at least one contactless biometric sensor on the skin or the clothing of a patient;

determining a result of the biometric measurement as to if the patient requires defibrillating intervention;

executing as needed a defibrillating sequence by means of said high-voltage power supply, said storage capacitor, and said at least two electrodes fixed to the skin of the patient.

11. Method according to claim 10, wherein said electrodes are fixed to the skin of the patient by means of adhesive films on the electrodes.

12. Method according to any one of claims 10 to 11, wherein said initial biometric measurement is or comprises an electrocardiographic measurement.
