Abstract

A defibrillator includes a defibrillator mainframe and a defibrillating electrode. The defibrillator mainframe includes a main control unit and a master device electrically connected to the main control unit. The defibrillating electrode comprises a slave device supporting a bus protocol, the master device and slave device being interconnected through a bus.

Claims

1. A defibrillator with a normalized electrode interface comprising:

a defibrillating electrode; and

a defibrillator mainframe comprising;

a main control unit; and

a master device connected to the main control unit;

wherein the defibrillating electrode comprises a slave device, and the master device and the slave device are connected through a bus;

wherein the master device is a 1-wire master device, the slave device on the defibrillating electrode is a 1-wire slave device, and the 1-wire master device and the 1-wire slave device are connected through a single wire;

wherein the 1-wire slave device further comprises a 1-wire storage module, the 1-wire storage module being connected to the 1-wire master device through the single wire; and

wherein the 1-wire storage module stores electrode expiration and condition information for use by a trace management function that prevents expired or damaged electrodes from being used.

2. The defibrillator according to claim 1, further comprising:

one or more indicator lights on the defibrillating electrode;

wherein the 1-wire slave device comprises a 1-wire control module for controlling the one or more indicator lights on the defibrillating electrode and collecting key information on the defibrillating electrode, the 1-wire control module being connected to the 1-wire master device through the single wire.
