Abstract

A temperature measuring apparatus includes a releasable probe chamber for housing a thermometry probe in which the chamber is isolated from the remainder of the thermometry apparatus. Preferably, the probe chamber is releasably attached to the apparatus and causes engagement or disengagement of at least one control switch of the apparatus depending on whether a probe is being removed or inserted into the probe chamber.

Claims (15)

1. A probe chamber for a thermometry apparatus, said apparatus including a temperature probe having at least one temperature responsive element connected to a housing, said probe being insertable into a body site of a patient to determine temperature thereof, said probe chamber including a probe well sized for receiving said probe wherein said probe chamber is releasably attachable to said housing and is wholly enclosed so as to provide a fluid-tight seal when attached to said housing.
2. A probe chamber as recited in Claim 1, wherein said chamber includes means for at least one of opening and closing a switch of said thermometry housing based on whether a probe is located in said probe well.
3. A probe chamber as recited in Claim 1, in which at least a portion of said chamber is made from a flexible material.
4. A probe chamber as recited in Claim 1 wherein said chamber is disposable.
5. A probe chamber as recited in Claim 1, wherein at least a portion of said well is made from a flexible material.
6. A probe chamber as recited in Claim 1, wherein said well includes an anti-microbial material.
7. A probe chamber as recited in Claim 2, wherein said chamber includes at least one axial portion made from a light transmissive material.
8. A probe chamber as recited in Claim 7, wherein said probe well is substantially made from a light transmissive material.
9. A thermometry apparatus used for measuring the temperature of a patient, said apparatus comprising:

a housing;

an elongate temperature sensitive probe including a probe well;

said housing further including a chamber releasably attachable to a receiving port of said housing and sized for retaining said temperature sensitive probe when said probe is not in use, said chamber providing a fluid-tight seal relative to the remainder of the interior of said housing.
10. An apparatus as recited in Claim 9, including at least one switch disposed in said housing interior and exterior to said probe receiving chamber and means provided in said chamber for automatically engaging said switch when a probe is one of added and removed from said chamber.
11. An apparatus as recited in Claim 9, wherein said switch includes a light emitter and a light detector, each of said light detector and light emitter being oppositely disposed relative to the receiving port of said housing and forming a connective light path, said probe well being made from a light transmissive material such that only the presence of said probe in said probe well disrupts the connective light path between said emitter and said detector.
12. An apparatus as recited in Claim 8, wherein said switch engaging means includes a protruding interior member disposed within said chamber, said protruding interior member being sized to engage said probe when said probe is inserted into said chamber wherein said chamber is made from a flexible material such that contact with said probe causes elastic deformation of said chamber into engagement with said switch.
13. An apparatus as recited in Claim 7, wherein said chamber is disposable.
14. An apparatus as recited in Claim 7, wherein the interior of said chamber includes an anti-microbial material.
15. An apparatus as recited in Claim 11, wherein said switch engaging means further includes windows provided in said probe well and arranged at a location which is along the light connective path when said probe chamber is placed in said housing.
