Abstract

In one embodiment, a defibrillation assembly energizable through case opening is provided. The defibrillation assembly includes an a magnetically triggered reed switch; a magnet positioned to keep the switch in an open position; 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 and a comprising a portion connected to the magnet by a mechanical interconnect, wherein an opening of the case displaces the connected case portion, which displaces the magnet far enough to transition the magnetically triggered reed switch into a closed position and causes the power to flow to the circuitry through the magnetically triggered reed switch.

Claims (29)

1 . A defibrillation assembly energizable through case opening, comprising:

a magnetically triggered reed switch;

a magnet positioned to keep the switch in an open position;

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 and a comprising a lid connected to the magnet that is separate from the lid by a wire, wherein a removal of the lid during an opening of the case displaces the mechanical interconnect, wire, which displaces the magnet far enough to transition the magnetically triggered reed switch into a closed position and causes the power to flow to the circuitry through the magnetically triggered reed switch.

2 . 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.

3 . A defibrillation assembly in accordance to claim 2 , wherein the controller unit makes the determination based on a time during which the controller receives the power through the switch.

4 . A defibrillation assembly in accordance to claim 3 , wherein the controller unit is configured to compare the time to a threshold and to make the determination based on the comparison.

5 . A defibrillation assembly in accordance to claim 4 , wherein the controller unit is configured to run a diagnostic check upon determining that the flow of the power was not accidental.

6 . 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.

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

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

9 . A defibrillation assembly in accordance to claim 8 , wherein the binding agent comprises plastic.

10 . A defibrillation assembly in accordance to claim 8 , wherein the magnet comprises neodymium iron borite.

11 . 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.

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

13 . 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 magnetically triggered reed switch.

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

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

instructions for opening of the case provided on the case.

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 16 , wherein the user interface comprises a plurality of lights positioned on at least one surfaces of the case.

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

20 . A defibrillation assembly in accordance to claim 16 , wherein the user interface is further configured to generate a tonal warning sound.
