Abstract

In one embodiment, a defibrillation assembly energizable through electrode enclosure manipulation is provided. The defibrillation assembly includes a magnetically triggered reed switch; an energy storage element that supplies power to the magnetically triggered reed switch; circuitry configured to generate a defibrillation waveform, wherein the circuitry is isolated from the energy storage element by the electromechanical component; and a case within which at least a portion of the housing is located and comprising an electrode enclosure within which a magnet is positioned that keeps the magnetically triggered reed switch in an open position, wherein an opening of the case that comprises removal of the magnet from the position causes the magnetically triggered reed switch to switch into a closed position and for the power to flow to the circuitry through the magnetically triggered reed switch.

Claims (29)

1 . A defibrillation assembly energizable through electrode enclosure manipulation, comprising:

a magnetically triggered reed switch;

an energy storage element that supplies power to the magnetically triggered reed switch;

circuitry configured to generate a defibrillation waveform, wherein the circuitry is isolated from the energy storage element by the magnetically triggered reed switch and wherein the circuitry is electrically unbiased when the power is not flowing from the energy storage element to the circuitry through the magnetically triggered reed switch; and

a case within which at least a portion of the circuitry is located, the case comprising an electrode enclosure within which a magnet is positioned that keeps the magnetically triggered reed switch in an open position, wherein an opening of the case that comprises removal of the magnet from the position causes the magnetically triggered reed switch to switch into a closed position and for the power to flow to the circuitry through the magnetically triggered reed switch.

2 . A defibrillation assembly in accordance to claim 1 , wherein the electrode enclosure is shaped to house one or more electrode pads for placement on a patient and delivery of the defibrillation waveform.

3 . A defibrillation assembly in accordance to claim 2 , wherein the electrode enclosure comprises a cavity in which the one or more pads are housed.

4 . A defibrillation assembly in accordance to claim 1 , 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.

5 . A defibrillation assembly in accordance to claim 4 , wherein the controller unit makes the determination based on a time during which the controller unit receives the power through the magnetically triggered reed switch.

6 . A defibrillation assembly in accordance to claim 4 , wherein the controller unit is configured to compare the time to a threshold and to make the determination based on the comparison.

7 . A defibrillation assembly in accordance to claim 6 , wherein the controller unit is configured to run a diagnostic check upon determining that the flow of the power was not accidental.

8 . A defibrillation assembly in accordance to claim 1 , wherein the magnet is a permanent magnet and the magnet obstructs switching of the magnetically activated reed switch into the closed position by one or more further magnets encountered post-manufacture.

9 . A defibrillation assembly in accordance to claim 1 , wherein the magnet is resistant to magnetic field changes due to external temperature fluctuations.

10 . A defibrillation assembly in accordance to claim 1 , wherein the magnet comprises a binding agent and a magnetic material.

11 . A defibrillation assembly in accordance to claim 10 , wherein the binding agent comprises plastic.

12 . A defibrillation assembly in accordance to claim 1 , wherein the magnet comprises ferrite.

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

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

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

15 . A defibrillation assembly in accordance to claim 1 , wherein the case is pocket-sized.

16 . A defibrillation assembly in accordance to claim 1 , wherein a size of the case is substantially a size of a mobile phone.

17 . A defibrillation assembly in accordance to claim 1 , further comprising a user interface comprises a plurality of lights positioned on one or more surfaces of the case.

18 . A defibrillation assembly in accordance to claim 17 , wherein the surfaces of the case comprise one or more of an interior surface of a lid of the case, a back surface of the case, and a surface of an electrode enclosure comprised in the case.

19 . A defibrillation assembly in accordance to claim 17 , wherein the user interface further comprises a speaker.

20 . A defibrillation assembly energizable through electrode enclosure manipulation, comprising:

a magnetically triggered reed switch;

an energy storage element that supplies power to the magnetically triggered reed switch;

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

a case within which at least a portion of the circuitry is located, the case comprising an electrode enclosure within which a magnet is positioned that keeps the magnetically triggered reed switch in an open position, wherein an opening of the case that comprises removal of the magnet from the position causes the magnetically triggered reed switch to switch into a closed position and for the power to flow to the circuitry through the magnetically triggered reed switch, wherein the circuitry comprises a controller unit configured to determine whether the flow of the power was accidental based on a time during which the controller unit receives the power through the magnetically triggered reed switch and to power down the circuitry upon making the determination that the flow of the power was accidental.
