Medical electrodes with long storage life
Medical electrodes are provided for use in applications that require long shelf life and/or shelf life at high temperatures. Some electrodes include high temperature adhesives and/or foams and an encapsulated electrolyte.
1. A medical electrode product comprising:
(a) an electrode comprising:
a housing;
a conductor within the housing; and
a conductive liquid disposed within a chamber that is constructed to separate the conductive liquid from the conductor until the electrode is to be used; and
(b) a package, in which said electrode is disposed prior to use, including an actuator device constructed to release said conductive liquid from the chamber when the electrode is removed from the package,
wherein said actuator device comprises rolls through which the electrode is pulled during removal from the package.
2. The product of claim 1 wherein said chamber comprises a breakable capsule.
3. The product of claim 2 wherein said breakable capsule comprises a glass ampule.
4. The product of claim 1 wherein said rolls are positioned to rupture said chamber during removal.
5. The product of claim 1 wherein said electrode further comprises an absorbent pad, positioned adjacent the conductor on the side of the conductor that is closer to the patient's skin when the electrode is in use.
6. The product of claim 1 wherein said conductor comprises a screen or mesh material.
