  • Defibrillator electrode adaptor
    Patent number: 4915109
    Abstract: Disclosed is an adaptor (28, 90) for use with a paddle electrode equipped defibrillator (10) that allows alternative use of disposable defibrillation electrodes. In some applications, the adaptor (28, 90) is positioned and retained in the paddle electrode stowage region (18) of the defibrillator (10) with the paddle electrodes (14, 16) being retained in an accessible position by the adaptor. Electrical contacts (75) and a cable (34) that are included in the adaptor electrically connect the paddle electrodes (14, 16) with connectors for disposable defibrillation electrodes, which are mounted at the distal end of the adaptor cable (34). When disposable defibrillation electrodes (36, 38) are placed in the adaptor cable connectors and positioned on the body of a patient, a defibrillation sequence is carried out utilizing the same controls and sequence that are used to defibrillate with the paddle electrodes.
