A defibrillation system includes an electrode set to contact a biological subject, and a portable electronic device supporting mobile wireless communications and coupled to the electrode set. The portable electronic device includes a processor and a memory unit. The memory unit stores program instructions which, when executed by the processor, enables the processor to obtain an electro-cardiac signal of the biological subject through the electrode set, and output a discharge command according to the electro-cardiac signal for delivering an electrical shock to the biological subject through the electrode set.

A package stores at least one electrode pad having a lead. The package includes an interior for storing the pad, and includes a portion that is openable to allow removal of the package from the leads. For example, the openable portion of the package may include a sealed seam through which the lead extends. The operator can peel apart the seam to both open the package and free the package from the lead. Where the pad is a defibrillator electrode pad, the ability to quickly and easily free the package from the lead may save precious seconds during the rescue of a patient in cardiac arrest. For example, freeing the package from the lead typically allows the operator a fuller view of and easier access to the defibrillator and the patient, and eliminates a potential distraction.

Handling or removal of a pair of defibrillator electrode pads from their package is detected in order to effectively time the issuance of prompts to guide the user. One plate of a capacitor is embedded in the package, the electrode pads and lead wires serving as the other plate. Impedance across the capacitor in an alternating current circuit is monitored to detect an increase in the distance between the pads and the package. The impedance level is determined, in a low-cost hardware solution, by rectifying and then integrating an output voltage of the capacitor to produce a voltage signal whose magnitude attenuates as the pads arc handled or removed. In one embodiment, the above methodology is time-division multiplexed with an alternative process that identifies handling or removal based on pad-to-pad impedance. In a further embodiment, the capacitive configuration is replaced with an inductive one.

Handling or removal of a pair of pre-connected defibrillator electrode pads from their package, or a compartment in the defibrillator, is detected in order to effectively time the issuance of prompts to guide the user. Detection occurs when an impedance level between the electrode pads varies sufficiently over time to indicate occurrence of the handling or removal event. The pads are preferably configured to leverage variability in the impedance that results from bending of pads during handling or removal.

The invention discloses a disposable defibrillator electrode board conductive sleeve and belongs to the technical field of medical apparatuses. The disposable defibrillator electrode board conductive sleeve comprises sponge arranged in a packaging bag.
