Abstract

A sensor means in the form of a substantially flat package for receiving and transmitting temperature indicating signals, to be monitored, comprising in combination, a first layer in the form of an annulus having an undersurface to adhere to the skin of a patient, a second layer in the form of a conductive sensing layer peripherally bounded by said first layer to block leakage from the second layer, and having an undersurface exposed downwardly for sealing contact with the skin of the patient, a foam layer extending above the first and second layers in adjacent relation therewith, a reflective layer extending over the foam layer, and an electrically conductive lead extending in contact with at least one of the first and second layers, and to the package exterior, as for controlling a warmer.

Claims

1. A sensor means in the form of a substantially flat package for receiving and transmitting signals, to be monitored and/or recorded, comprising in combination:

a) a first layer in the form of an annulus having an undersurface to adhere to the skin of a patient,

b) a second layer in the form of a conductive sensing layer peripherally bounded by said first layer to block leakage from the second layer, and having an undersurface exposed downwardly for sealing contact with the skin of the patient,

c) a foam plastic layer extending over the entire top surfaces of the first and second layers and adhesively bonded to said top surfaces whereby the foam plastic layer blocks heat transfer upwardly from the first and second layers, in adjacent relation therewith,

d) a reflective layer extending over the foam layer, to reflect impinging heat radiation away from the foam layer,

e) an electrically conductive lead extending under said first and second layers and in contact with at least one of the first and second layers, and also extending to the package exterior,

f) said foam plastic layer assisting in stabilizing the relative positions of the first and second layers, above the level of the lead.

g) a thin layer of adhesive adhered to the undersides of said first and second layers,

h) and a strip-off protective plastic film layer extending under the entire adhesive layer, beneath said first and second layers undersides.

2. The combination of claim 1 wherein said first layer consists of a hydrocolloid material.

3. The combination of claim 1 wherein said second layer undersurface is in the same plane as defined by a lower annular surface of the first layer.

5. The combination of claim 1 wherein said packages has layered configuration, and including a warmer connected to said lead, outside the package.

6. The combination of claim 1 wherein said reflective layer consists of gold.

7. The combination of claim 1 including adhesive material between said foam layer and said first and second layers, and adhesive material between said foam layer and said reflective layer.

8. The combination of claim 1 wherein the dimensions of said first layer are approximately as follows:

9. The combination of claim 8 wherein the dimensions of said second layer are approximately as follows:

10. The combination of claim 9 wherein the dimensions of said foam layer are approximately as follows:

11. The combination of claim 9 wherein the dimensions of said reflective layer are approximately as follows:
