Sealed medical electrode package
A sealed medical electrode package comprises first and second electrodes each comprising a conductive layer ( 14 ) disposed on one major surface of a flexible nonconductive backing sheet ( 10 ). The electrodes are disposed with their conductive layers ( 14 ) face-to-face and their backing sheets separably sealed together around their peripheral edges so that the backing sheets form a substantially gas-impermeable enclosure containing the conductive layers. In an alternative embodiment (FIG. 6 ) a respective electrical contact extends through each backing sheet into electrical contact with the respective conductive layer, and a substantially gas-impermeable packaging material encloses the electrodes. The packaging material has a respective aperture exposing each electrical contact, the periphery of each aperture being sealed to the backing sheet around the respective contact.
1. A sealed medical package comprising first and second electrodes each comprising a conductive layer disposed on one major surface of a flexible non-conductive backing sheet, the electrodes being disposed with their conductive layers face-to-face and their backing sheets separately sealed together around their peripheral edges so that the backing sheets form a substantially gas-impermeable enclosure containing the conductive layers, each conductive layer having a respective electrical connector.
2. A package as claimed in claim 1 , wherein each electrical connector comprises an electrical contact extending through a respective backing sheet into electrical contact with the respective conductive layer.
3. A package as claimed in claim 2 , wherein each conductive layer comprises a conductive gel and a release liner is disposed between the facing surfaces of the conductive layers.
4. A package as claimed in claim 3 , wherein the peripheral edges are sealed together by adhesive.
5. A package as claimed in claim 2 , wherein the peripheral edges are sealed together by adhesive.
6. A package as claimed in claim 1 , wherein each conductive layer comprises a conductive gel and a release liner is disposed between the facing surfaces of the conductive layers.
7. A package as claimed in claim 6 , wherein the peripheral edges are sealed together by adhesive.
8. A package as claimed in claim 1 , wherein the peripheral edges are sealed together by adhesive.
9. A package as claimed in claimed in any one of claims 1 - 8 , further including a pair of tabs each fixed to or integral with a respective backing sheet to allow the electrodes to be pealed apart.
10. A sealed medical electrode package comprising first and second electrodes each comprising a conductive layer disposed on one major surface of a flexible non-conductive backing sheet, the electrodes being disposed with their conductive layers face-to-face, a respective electrical contact extending through each backing plate sheet into electrical contact with the respective conductive layer, and a substantially gas-impermeable packaging material enclosing the electrodes, the packaging material having a respective aperture exposing each electrical contact, the periphery of each aperture being sealed to the backing sheet around the respective contact.
11. A package as claimed in claim 10 , wherein the packaging material comprises two packaging sheets enclosing the electrodes between them and releasably sealed together around their peripheral edges.
12. A package as claimed in claim 11 , further including a pair of tabs each fixed to or integral with a respective packaging sheet to allow the packaging sheets to be peeled apart.
13. A package as claimed in claim 11 , wherein the peripheral edges of the packaging sheets are heat-sealed together.
14. A package as claimed in claim 12 , wherein the peripheral edges of the packaging sheets are heat-sealed together.
15. A package as claimed in any one of claims 10 to 13 and 14 , wherein each conductive layer comprises a conductive gel and a release liner is disposed between the facing surfaces of the conductive layers.
