Abstract

In one embodiment, a defibrillation assembly energizable through pad removal is provided. The defibrillation assembly includes a mechanical switch that is in an open position when the circuitry is not in use; an energy storage element that supplies power to the mechanical switch; circuitry configured to generate a defibrillation waveform, wherein the circuitry is isolated from the energy storage element by the mechanical switch; andelectrode pads through which the defibrillation waveform is delivered to a patient, wherein a removal of at least one of the electrode pads from an initial position to a further position causes the power to flow to the circuitry through the mechanical switch.

Claims (28)

1. A defibrillation assembly energizable through pad removal, comprising:

a mechanical switch that is in an open position when the circuitry is not in use;

an energy storage element that supplies power to the mechanical switch;

circuitry configured to generate a defibrillation waveform, wherein the circuitry is isolated from the energy storage element by the mechanical switch; and

electrode pads through which the defibrillation waveform is delivered to a patient, wherein a removal of at least one of the electrode pads from an initial position to a further position causes the power to flow to the circuitry through the mechanical switch, wherein the circuitry comprises a controller unit configured to determine whether the flow of the power was accidental and to power down the circuitry upon making the determination the flow of the power was accidental.

2. A defibrillation assembly in accordance to claim 1 , wherein the mechanical switch is mechanically connected to the at least one electrode pad, wherein a removal of the at least one electrode pad from the initial position transitions the mechanical switch into a closed position.

3. A defibrillation assembly in accordance to claim 1 , further comprising a mechanical interconnect one end of which is attached to the at least one pad and another end of which is attached to the mechanical switch.

4. A defibrillation assembly in accordance to claim 3 , wherein the at least one pad is connected to the circuitry via flexible leads and wherein the mechanical interconnect is attached to one of the flexible leads.

5. A defibrillation assembly in accordance to claim 4 , wherein the circuitry and the mechanical switch are located inside a housing and wherein the flexible leads and the mechanical interconnect extend into the housing.

6. A defibrillation assembly in accordance to claim 5 , wherein the at least one electrode pad is secured in the initial position by a seal and the removal of the at least one electrode pad from the initial position requires a removal of the seal.

7. A defibrillation assembly in accordance to claim 3 , wherein the mechanical interconnect comprises a wire.

8. A defibrillation assembly in accordance to claim 1 , wherein the controller unit makes the determination based on a time during which the controller receives the power through the mechanical switch.

9. A defibrillation assembly in accordance to claim 1 , wherein the controller unit makes the determination based on a time during which the controller receives the power through the mechanical switch.

10. A defibrillation assembly in accordance to claim 9 , wherein the controller unit is configured to compare the time to a threshold and to make the determination based on the comparison.

11. A defibrillation assembly in accordance to claim 1 , wherein the controller unit is configured to run a diagnostic check upon determining that the removal of the pads was not accidental.

12. A defibrillation assembly in accordance to claim 11 , wherein a portion of the circuitry is pre-charged following a completion of the diagnostic check.

13. A defibrillation assembly in accordance to claim 12 , further comprising:

the controller unit configured to determine whether the pads have been applied to a patient following the pre-charging.

14. A defibrillation assembly in accordance to claim 13 , further comprising:

the controller unit configured to determine whether the patient is experiencing a shockable event following the application of the pads, wherein the circuitry generates the defibrillation waveform upon the detection of the shockable event.

15. A defibrillation assembly in accordance to claim 11 , further comprising:

an onboard log in which a record of an activation of the circuitry due to the flow of the power is made.

16. A defibrillation assembly in accordance to claim 1 , further comprising:

a user interface configured to provide a signal regarding the flow of the power to the circuitry.

17. A defibrillation assembly in accordance to claim 16 , further comprising:

the user interface configured to provide warning prior to delivery of the defibrillation waveform to the patient.

18. A defibrillation assembly in accordance to claim 1 , wherein the energy storage element comprises a battery.

19. A defibrillation assembly in accordance to claim 1 , wherein the circuitry is electrically unbiased when the power is not flowing from the energy storage element to the circuitry through the mechanical switch.
