Abstract

A defibrillator paddle includes a pediatric electrode of relatively small size attached to a mounting portion of a housing having a handle. An adult electrode assembly is releasably mounted to the mounting portion of the housing by a quick release latch mechanism. The adult electrode assembly includes an adult electrode larger than the pediatric electrode. The pediatric electrode nests within the adult electrode assembly and a spring makes electrical contact between the electrodes when the adult electrode assembly is mounted.

Claims

1. A defibrillator paddle comprising in combination:

a paddle housing including a handle and a mounting portion;

an electrically conductive pediatric electrode attached to said mounting portion and spaced from said handle;

electrical circuit means including switch means mounted on said housing for applying a defibrillator shock signal to said pediatric electrode;

and an adult electrode assembly releasably attached in an assembled condition to said mounting portion;

said adult electrode assembly including an electrode base and an adult electode attached to said base;

said adult electrode having a surface area larger that the surface area of said pediatric electrode;

said pediatric electrode being nested inside of said adult electrode assembly in said assembled condition;

contact means carried by said adult electrode assembly for electrically connecting said pediatric electrode to said adult electrode in said assembled condition; and

a quick release latch engageable between said adult electrode assembly and said paddle housing including first and second interlocking elements on said mounting portion and said electrode base and further including a catch and a resiliently movable latch spaced from said first and second elements on mounting portion and said electrode base;

said latch including a lever mounted in said electrode base for pivotal movement and a spring for resiliently biasing said lever into engagement with said catch.

2. The defibrillator paddle of claim 1, said housing including two joined housing segments and said catch comprising a member attached to both said segments for assisting in holding them together.

3. The defibrillator paddle of claim 1, said pediatric electrode and said adult electrode being generally shaped as flat planar members and being generally parallel to one another and spaced apart in said assembled condition.

5. The defibrillator paddle of claim 1, said paddle housing including two joined housing segments, said pediatric electrode engaging both said housing segments for assisting in holding them together.

4. The defibrillator paddle of claim 6, said contact means comprising a resiliently compressible electrically conductive spring member sandwiched in compression between said electrodes in said assembled condition.
