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. In other applications, the adaptor (90) is affixed to a portion of the defibrillator cabinet (92) or another suitable place.

Claims

1. An adaptor for use with a defibrillator of the type that includes a pair of paddle electrodes, said adaptor for converting the defibrillator for alternative use of the defibrillator with a pair of disposable electrodes other than the paddle electrodes, said adaptor comprising:

an adaptor body, said adaptor body including means for receiving and retaining in a predetermined position the paddle electrodes of the defibrillator;

first and second adaptor contact means, said first adaptor contact means being mounted to provide electrical contact with the first one of the pair of paddle electrodes when that paddle electrode is received and retained by said adaptor body, said second adaptor contact means being mounted to provide electrical contact with the second one of the pair of paddle electrodes when that paddle electrode is received and retained by said adaptor body; and

conductor means for electrically connecting said first adaptor contact means to a first of said disposable electrodes and for electrically connecting said second adaptor contact means to a second of said disposable electrodes.

2. The adaptor of claim 1 wherein said defibrillator further is of the type that includes a region for stowage of the pair of paddle electrodes and wherein said adaptor body is adaptor for placement in said region for stowage when the paddle electrodes are received and retained.

3. The adaptor of claim 2 wherein the electrode stowage region of the defibrillator includes retainment means for retaining the paddle electrodes in a stowed condition and said adaptor body further includes means for engaging the retainment means of the electrode stowage region.

4. An adaptor for use with a paddle electrode equipped defibrillator of the type that includes a stowage facility for the paddle electrodes, said adaptor for converting the defibrillator for alternative use with disposable defibrillation electrodes, said adaptor comprising:

an adaptor body dimensioned and configured for placement in the stowage facility of the defibrillator, said adaptor body including means for receiving the paddle electrodes of the defibrillator;

first and second adaptor contact means, said first adaptor contact means being mounted to provide electrical contact with the first one of the paddle electrodes when that paddle electrode is received by said adaptor body, said second adaptor contact means being mounted to provide electrical contact with the second one of the paddle electrodes when that paddle electrode is received by said adaptor body; and

conductor means for electrically connecting said first adaptor contact means to a first of said disposable electrodes and for electrically connecting said second adaptor contact means to a second of said disposable electrodes.

5. The adaptor of claim 4 wherein said means for receiving the paddle electrodes includes means for retaining the paddle electrodes in a predetermined position.

6. The adaptor of claim 5 wherein the electrode stowage facility of the defibrillator includes means for retaining the paddle electrodes in a stowed condition and said adaptor body further includes means for retainment by the retainment means of the electrode stowage facility.

7. In a paddle electrode equipped defibrillator of the type including a stowage region for the paddle electrode and means for temporary retainment of the paddle electrodes in the stowage region, the improvement comprising an adaptor that facilitates alternative use of said defibrillator with a pair of electrodes other than said paddle electrodes, said adaptor being dimensioned and configured for placement in said stowage region and for temporary retainment by said means for temporary retainment of said paddle electrodes, said adaptor including means for temporary retainment of said paddle electrodes, said adaptor further including means for completing a first electrical circuit path between a first one of said other electrodes and a first one of said paddle electrodes when said first paddle electrode is temporarily retained by said adaptor and means for completing a second electrical circuit path between a second one of said other electrodes and a second one of said paddle electrodes.
