Abstract

Disposable, zero-heat-flux, deep tissue temperature probes are constructed using a support assembly constituted of a flexible substrate that supports elements of the probe. One support assembly embodiment includes a folded substrate with a heater and thermal sensors disposed on it. Another support assembly includes multiple sections separable into strata supporting a covering guard heater, a central thermal sensor, and a thermal sensor displaced at least radially from the central thermal sensor.

Claims

1. A support assembly for a deep tissue temperature probe, comprising:

a substrate with two sides;

a plurality of sections defined in the substrate, in which each section is joined to at least one adjacent section at a peripheral location common to both sections;

a first thermal sensor and a second thermal sensors, each supported on a respective one of two adjacent sections;

a heater supported on the substrate; and

,

a pattern of slits in one of the two adjacent sections, wherein each of the pattern of slits comprises an opening extending within and through the substrate, wherein the pattern of slits in the one of the two adjacent sections includes at least three slits.

2. The support assembly of claim 1, wherein the first thermal sensor is mounted on a surface of a first section of the two adjacent sections, the second thermal sensor is mounted on a surface of a second section of the two adjacent sections, each section of the two adjacent sections has a pattern of slits, the pattern of slits define a plurality of zones in the heater, and the sections are capable of being folded together such that the slits are aligned and open through all of the sections.

3. The support assembly of claim 2, wherein the zones are wedge shaped and the slits are radial slits.

4. The support assembly of claim 2, wherein the zones are arcuately shaped and the slits are arcuately-shaped slits.

5. The support assembly of claim 2, wherein the zones are partially circular and the slits are partially circular slits.

6. A support assembly for a deep tissue temperature probe, comprising:

a flexible substrate with at least two sections;

a plurality of zones defined in one of the sections;

two thermal sensors, each supported on a respective one of two adjacent sections, at least one of the sections having a pattern of slits, wherein the pattern of slits includes at least three slits, wherein each of the pattern of slits comprises an openings extending within and through the substrate; and

,

a heater supported on the flexible substrate and including a heater zone positioned on each of the plurality of zones.

7. The support assembly of claim 6, wherein the plurality of zones are wedge shaped and form a pinwheel configuration in which each zone is flexible independently of the other one of the plurality of zones.

8. The support assembly of claim 6, wherein the zones are arcuately shaped and each zone is flexible independently of any other zone.

9. The support assembly of claim 6, wherein the zones are partially circularly shaped and each zone is flexible independently of any other zone.
