Nasal vibration transducer
A vibration transducer specially configured for attachment to a subject's nose for producing an electrical output signal relating to a subject's snoring pattern. The transducer is shaped so as to have a rectangular portion for bridging the dorsum at least one polygonal pad area adapted to be adhesively secured to the ala nasi. The transducer is a laminated arrangement incorporating a polyvinylidene fluoride film exhibiting piezoelectric properties.
1. A thin, flexible, laminated, vibration transducer adapted for placement on a subject's nose for producing an electrical signal related to snoring episodes, the laminated transducer comprising:
(a) an outer layer of adhesive tape having adhesive on one major surface thereof;
(b) an intermediate layer of a flexible, conformable plastic film exhibiting piezoelectric properties and having a pattern of metallization on opposed major surfaces thereof, the intermediate layer being co-extensive with at least a predetermined portion of the outer layer;
(c) first and second elongated conductors, each having an electrode at one end and an electrical connector at an opposite end, the electrode on the first conductor held in contact with the pattern of metallization on one of the opposed major surfaces of the layer of plastic film by the outer layer of adhesive tape;
(d) an inner layer of adhesive tape having adhesive on each opposed major surfaces thereof, the electrode on the second conductor held in contact with the pattern of metallization on another of the major surfaces of the layer of plastic film by the adhesive on one major surface of the inner layer of adhesive tape; and
(e) the outer and inner layers having a generally rectangular portion adapted to span a dorsum of the nose of the subject and an integrally attached pad portion for placement on a ala nasi.
2. The vibration transducer as in claim 1 wherein the outer and inner layers have a generally rectangular portion for spanning a dorsum of the nose of the subject and an integrally attached pad portion on each end of the rectangular portion for placement on each ala nasi of the subject's nose.
3. The vibration transducer of claim 1 and further including:
(a) a layer of release paper adhered to the adhesive on another major surface of the inner layer of adhesive tape.
4. The vibration transducer of claim 2 and further including:
(a) a layer of release paper adhered to the adhesive on another major surface of the inner layer of adhesive tape.
5. The vibration transducer of claim 2 wherein the intermediate layer has the same shape configuration as the outer and inner layers.
6. The vibration transducer of any one of claims 1 - 5 wherein the plastic film is polyvinylidene fluoride.
7. The vibration transducer as in claim 1 wherein the predetermined portion of the outer layer with which the inner layer is coextensive is the pad portion.
8. The vibration transducer as in claim 2 wherein the predetermined portion of the outer layer with which the intermediate layer is coextensive comprise the rectangular portion and the pad portions on each end of the rectangular portion.
