Abstract

A mechanical defibrillator comprising an impact member configured to deliver a mechanical impact of a preset force to the chest of a subject in need of a defibrillation shock.

Claims

1. A mechanical defibrillator comprising an impact member configured to deliver a controllable mechanical impact of a preset force to the chest of a cardiac arrest victim.

2. The mechanical defibrillator of claim 1 wherein said impact member is mounted on a frame adapted to be placed on the victim'"'"'s chest and wherein the defibrillator further comprises a rechargeable energy storage element coupled to said impact member, said energy storage element is configured to be charged when said impact member is elevated above said frame.

3. The mechanical defibrillator of claim 2 further comprising a discharging mechanism configured for releasing energy stored in the energy storage element into impact energy of said impact member.

4. The mechanical defibrillator of claim 2 further including a charging mechanism for controllably charging said energy storage element while simultaneously elevated said impact member to a controllable height above the chest of the victim.

5. The device of claim 1 wherein said preset force is of a fixed value.

7. The device of claim 1 wherein said preset force can be adjusted to up to 180 Kg.

8. The defibrillator of claim 1 further comprising an indicator for indicating said preset force.

9. The defibrillator of claim 1 further comprising at least one sensor for sensing heart'"'"'s activity of the subject.

10. The defibrillator of claim 7 further comprising analyzing means to analyzing said heart activity and to detect ventricular fibrillation.

11. The defibrillator of claim 8 further comprising halting means to prevent discharging if ventricular fibrillation is not detected.

12. The defibrillator of claim 4 wherein the charging mechanism is manually operated.

13. The defibrillator of claim 3 further comprising activating elements for manually activating said discharging mechanism.

14. The defibrillator of claim 13 wherein said activating elements comprises a discharger element configured to release the impact member, a stopper element configured to prevent said discharging member from discharging the impact element and a stopper releasing element configured to release said stopper element for enabling discharging.

15. The defibrillator of claim 2 wherein said frame further comprises two handles to be held by both hands of an operator of the device.

16. The defibrillator of claim 3 further comprising a main stopper configured to prevent discharging unless the defibrillator is pressed properly against the subject'"'"'s chest.

17. The defibrillator of claim 2 wherein said rechargeable energy storage element is a mechanical energy storage element.

18. The defibrillator of claim 3 wherein said rechargeable energy storage element is a spring.

19. The defibrillator of claim 3 wherein said rechargeable energy storage element is a torque spring.

20. The defibrillator of claim 1 wherein said impact member is a cylindrical weight of about 100-400 gr and of about 20-50 mm diameter.

6. The device of claim 6 wherein said fixed value is in the range of 70 to 100 Kg.

21. A mechanical defibrillator for delivering a mechanical impact of a preset force to a sulbject'"'"'s chest, the device comprising:

a frame adapted to be placed on a subject'"'"'s chest;

an impact weight mounted on said frame configured to be elevated above the subject'"'"'s chest;

a chargeable element coupled to said impact element;

a charging mechanism for charging said chargeable element and for elevating said impact weight; and

a discharging mechanism for discharging energy stored in said chargeable element to actuate said impact weight to deliver a mechanical impact to the subject'"'"'s chest.

22. A method for delivering a defibrillation shock to a cardiac arrest victim comprising the step of delivering a controllable mechanical impact of a preset force to the chest of the victim by means of a mechanical device provided with an impact member.
