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 defibrillating electrode comprising:

an electrode terminal; and

a slave device supporting a bus protocol, the slave device being connected to a master device through a single wire bus;

wherein the slave device further comprises a 1-wire storage module, the 1-wire storage module being connected to the master device through the single wire bus; 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 defibrillating electrode according to claim 1, wherein the master device is a 1-wire master device.

3. The defibrillating electrode according to claim 1, wherein the slave device on the defibrillating electrode is a 1-wire slave device.

4. The defibrillating electrode according to claim 3, wherein the 1-wire slave device comprises a 1-wire control module for controlling one or more indicator lights on the defibrillating electrode and collecting key information, the 1-wire control module being connected to the master device through the single wire bus.
