Abstract

Claims (22)

1 . A defibrillation assembly energizable through magnet removal, 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;

a case within which at least a portion of the circuitry is located and comprising a printed circuit board (PCBA) enclosure within which a magnet is positioned that keeps the magnetically triggered reed switch in an open position and an electrode enclosure separate from the PCBA enclosure in which electrode pads are stored, 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 a micro-controller unit is configured to determine whether the opening of the case was accidental and to power down the circuitry upon making a determination the opening of the case was accidental.

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

4 . A defibrillation assembly in accordance to claim 3 , wherein the micro-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 1 , wherein the magnet is a permanent magnet and the magnet obstructs switching of the magnetically activated reed switch into a closed position by one or more further magnets encountered post-manufacture.

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

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

8 . A defibrillation assembly in accordance to claim 7 , wherein the binding agent comprises plastic.

9 . A defibrillation assembly in accordance to claim 1 , wherein the magnet comprises samarium cobalt.

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

a micro-controller unit configured to determine whether the electrode pads have been applied to a patient.

11 . A defibrillation assembly in accordance to claim 10 , further comprising:

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

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 , wherein a size of the case is a size of a mobile phone.

16 . 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.
