Abstract

A cardiac defibrillator paddle in which the elctrode surface is provided with a removable cap. This permits the electrode to have its conductive paste pre-applied, with the cap readily removable for immediate use.

Claims

1. At least one cardiac defibrillator electrode paddle conductive paste storage system comprising:

an insulating handle suitable for grasping;

an end flange connected to said handle at one end thereof, said end flange being configured with peripheral key means,

an electrode face mounted on a side of said end flange opposite to said handle, said face covering a substantial portion of said side;

a resilient and reusable cover member peripherally configured with the complement of said key means to permit tight-fit removable mounting of said cover member to said end flange, said cover member being removably connected with said end flange and together defining a sealed space between said electrode face and the inside surface of said cover member;

conductive fluid stored in said sealed space whereby the orientation of said at least one paddle is not critical to the storage of said conductive fluid and whereby the distance between said stored conductive fluid of one of said at least one paddle and said stored conductive fluid of another of said at least one paddle is not necessarily a fixed distance;

another flange connected to said handle at a predetermined distance from said end flange to limit travel of said handle grasping towards said end flange;

means for electrically connecting said electrode face to a power source and for electrically insulating said handle and said another flange from said electrode face;

and tab means protruding from said cover member for facilitating removal of said cover member and exposure of said conductive fluid.
