Abstract

An object of the present invention is to prevent "low-temperature burn" that occurs on account of heat generation by the LED in an oximeter probe. The oximeter probe comprises adhesive tape which has an opening formed at the site where the LED is fitted, and a heat-dissipating plate is provided in the opening.

Claims

1. An oximeter probe comprising:

an adhesive tape having an adhesive surface and a surface that is opposite to the adhesive surface, the adhesive surface adapted to be bonded to skin of a living body, the adhesive tape having an opening formed therethrough;

a light-emitting device and a light-receiving device spaced from each other on the adhesive surface of the adhesive tape, the light-emitting device being disposed at a location which is aligned with the opening of the adhesive tape; and

a heat-dissipating plate being fitted into the opening and being thermally connected to said light-emitting device, wherein the heat dissipating plate covers at least a part of the surface of the adhesive tape that is opposite to the adhesive surface of the adhesive tape.

2. An oximeter probe as claimed in claim 1, wherein the heat dissipating plate is made of one of silicone resin or silicone rubber.

3. An oximeter probe comprising:

an adhesive tape having an adhesive surface and a surface that is opposite to the adhesive surface, the adhesive surface adapted to be bonded to skin of a living body, the adhesive tape having an opening formed therethrough;

a light-emitting device and a light-receiving device spaced from each other on the adhesive surface of the adhesive tape, the light-emitting device being disposed at a location which is aligned with the opening of the adhesive tape;

a heat-dissipating plate being fitted into the opening and being thermally connected to said light-emitting device; and

a flexible printed-wiring board which is bonded to the adhesive surface of the adhesive tape, the light-emitting device and the light-receiving device being attached to said flexible printed-wiring board, said light-emitting device and said heat-dissipating plate being thermally connected by said flexible printed-wiring board.
