Abstract
Defibrillator electrodes are sealed to the inside of a rigid enclosure. The enclosure is hinged to open and expose the electrodes for deployment. The electrode gel is sealed against moisture loss between the moisture impervious electrode backing and the inner surface of the enclosure. The enclosure may further include an electrical circuit for electrode self-testing, the circuit being broken when the enclosure is opened.
Claims20
An electrode and enclosure for a medical monitoring or therapy instrument comprising:
- an enclosure formed of a substantially rigid, moisture impervious material and having an inner surface against which one or more electrodes may be sealed, the enclosure having an open state in which electrodes inside the enclosure may be accessed and a closed state;
- first and second electrodes each having a substantially moisture-impervious outer layer, an electrically conductive gel layer, the outer layer of each electrode being peripherally sealed to the inner surface of the enclosure prior to use;
- an electrical circuit disposed on the enclosure comprising first and second mateable connectors which are in electrical contact with the gel layer of each electrode when the electrodes are sealed to the inner surface of the enclosure, the mateable connectors being open when the enclosure is in its open state and the mateable connectors being mated when the enclosure is in its closed state to electrically connect the gel layers of the electrodes;
- and
- a closing device which retains the enclosure in its closed state prior to use of the electrodes,
- wherein the electrode further comprises a metallic layer located between the outer layer and the gel layer.
An enclosure for a pair of electrodes for use in a defibrillator comprising:
- a hinged enclosure, having an open state and a closed state, formed of a substantially rigid, moisture impervious material;
- first and second release surfaces formed on an inner surface of the hinged enclosure;
- first and second heat sealing surfaces disposed on an inner surface of the hinged enclosure and about the periphery of the first and second release surfaces;
- first and second conductive elements disposed on the first and second release surfaces;
- first and second mateable connector ends disposed on the enclosure in conductive contact with first and second conductive elements, the mateable connector ends being mated when the enclosure is in the closed state;
- and
- a closing device which retains the enclosure in the closed state.
