Abstract: An automated external defibrillator (AED), comprising two pads to be placed on a patient, multiple electrode pairs provided on or between the two pads to perform multiple functions of electrical measurement and stimulation of the patient's heart, a switching circuit and a shock generation circuit connected to the multiple electrode pairs and a controller connected to the switching circuit and the shock generation circuit, wherein the controller is configured to perform spatial division multiplexing by rapidly switching between the multiple electrode pairs to automatically perform the multiple functions of electrical measurement and stimulation of the patient's heart using the multiple electrode pairs in multiple directions.

Abstract: There is provided herein a small form factor portable automatic external defibrillator (AED) having a controller, a charging circuit and a discharge circuit to discharge capacitors using a respective pair of electrode pads. The defibrillator may be separable into two portions at a bisection. Each portion may have a respective electrode pad on corresponding upper surfaces thereof for electrical contact with the chest. A circuit completion wire may complete the electric circuit between the two portions. The defibrillator may comprise a peel-off layer covering both adjacent electrodes. The peel-off layer is adhered to the board at peripheral edges thereof. As such, when pressure is applied to the bisection, the board snaps into the two portions and the peel-off layer simultaneously peels from the portions. In this way, the defibrillator may be deployed quickly with a single break apart manoeuvre.
