Abstract
A sensor for use with a polysomnograph in a sleep lab setting is made reusable by laminating a PVDF film and associated lead contacts within a flexible, moisture-impervious plastic envelope that is hermetically sealed about its periphery. Lead terminals within the envelope are adhered to the metalized surfaces of the PVDP film using a conductive adhesive which inhibits dislodgement of the leads from the sensor even with rough handling and cleaning.
Claims6
A reusable snore/air flow sensor comprising:
- (a) a polyvinylidene fluoride (PVDF) film of a predetermined shape configuration and having a layer of metallization on opposed major surfaces of said film;
- (b) a first and a second insulated lead wires each having a contact member affixed to an uninsulated end portion thereof;
- (c) a conductive adhesive adhering the contact members on the first and the second lead wires to the layers of metallization of the opposed major surfaces of the PVDF film;
- (d) a first layer of double-sided adhesive tape, the layers being of said predetermined shape configuration and overlaying said contact members and a portion of the insulated lead wires and adhered on a first side to the metalized PVDF film, forming a contiguous seal with the adhesive tape;
- (e) a second layer of double-sided adhesive tape, the layers being of said predetermined shape configuration and overlaying said contact members and a portion of the insulated lead wires and adhered on a second side to the metalized PVDF film, forming a contiguous seal with the surface of the adhesive tape;
- and
- (f) a first and a second outermost layers of a moisture impervious, flexible, thermoplastic material, the first outermost layer being adhered to the first layer of double-sided adhesive tape, forming a contiguous seal with the surface of the adhesive tape, and the second outermost layer being adhered to the second layer of double-sided adhesive tape, forming a contiguous seal with the surface of the adhesive tape, and with perimeter portions of the first and second outermost layers being bonded to one another forming a non-porous permanent encapsulation.
