Abstract

A digital thermometer with enhanced conformity to the anatomy, such as in and around the mouth of a human being. A non-linear probe has a temperature sensor at a first end adapted to be inserted into the mouth and under the tongue. An intermediate portion of the probe is shaped to rest on the lower lip and/or teeth. The probe may also be flexible such that it may be bent into the desired non-linear configuration prior to use, in which case the intermediate portion of the probe may be linear prior to use. A display component displays the measured temperature. Electronic circuitry receives a temperature signal from the temperature sensor, translates the signal into a value representative of the measured temperature, and provides the translated value to the display for displaying the temperature.

Claims

1. A digital thermometer for measuring the temperature of a living being by inserting a portion of the thermometer in the mouth of the living being comprising:

a probe with first and second ends and an intermediate portion of the probe disposed between the first and second ends, the intermediate portion having a non-linear shape and being moveable between the non-linear shape and a substantially linear shape,

a temperature sensor disposed near the first end of the probe,

a housing, separate from the probe and having a display for displaying a temperature measured by said thermometer, said housing having a portion configured to allow a user to move the probe between its linear and non-linear shapes without the user contacting the probe with his or her fingers, and

electronic circuitry, within said housing, in communication with said temperature sensor to receive a temperature signal from said temperature sensor, to translate said temperature signal into a value representative of the temperature measured by the temperature sensor, and to communicate the translated value to the display for displaying the measured temperature.

2. The thermometer of claim 1 wherein the non-linear shape comprises a curve of constant radius.

3. The thermometer of claim 1 wherein the probe includes a material selected to enable the intermediate portion to remain in a shape to which it is moved until it is moved to another shape.

4. The thermometer of claim 3 wherein the material comprises a stiffening core.

5. The thermometer of claim 4 wherein the core comprises a wire.

6. The thermometer of claim 4 wherein the core comprises a segmented stiffening member.

7. The thermometer of claim 3 wherein the material comprises a bendable polymer.

8. The thermometer of claim 1 wherein the housing includes a chamber configured to store a plurality of probe covers.

9. The thermometer of claim 8 wherein the chamber includes an opening configured to receive the probe so that the probe may be inserted into one of the probe covers in the chamber, and the probe and probe cover pulled from the chamber.

10. The thermometer of claim 1 wherein said portion comprises a slot into which the probe can be partially inserted.

11. The thermometer of claim 1 wherein the probe includes a relatively hard core and a relatively softer polymeric sheath, the sheath enclosing the core and being exposed for contact with the living being'"'"'s mouth.

12. The thermometer of claim 1 wherein the display is pivotably mounted on a portion of the housing.

13. The thermometer of claim 1 further comprising a control button mounted in the vicinity of the probe.

14. The thermometer of claim 1 wherein the probe is connected to the housing by a cord.

15. The thermometer of claim 14 wherein the housing is configured to allow the cord to retract into the housing when the thermometer is not in use.

16. The thermometer of claim 15 further comprising an actuator configured to allow the user to control the retraction of the cord.

17. The thermometer of claim 15 wherein the housing includes a chamber configured to store the probe.

18. The thermometer of claim 8 wherein the chamber is configured to receive a replaceable probe cover cartridge.

19. The digital thermometer of claim 1 wherein said probe includes an exterior portion formed from a relatively soft material and an internal stiffening element formed from a relatively harder material.

20. The digital thermometer of claim 19 wherein said internal stiffening element comprises a malleable metal.

21. The digital thermometer of claim 1 wherein said probe is formed from a ductile polymer with low elasticity that permits shaping of the intermediate portion of the probe into a desired non-linear shape.

22. The digital thermometer of claim 1 wherein said intermediate portion of said probe is linear prior to being shaped into said non-linear shape.

23. The digital thermometer of claim 1 wherein said intermediate portion of the probe is shaped to rest on the lower lip and/or teeth of the living being.
