Abstract
The present invention includes a process and apparatus for determining the temperature of a sample such as urine without contacting the sample itself. A portable device is used to carry the temperature measuring apparatus. The sample of urine is placed in a plastic container on an adjustable support and the temperature is measured by an infrared pyrometer.
Claims6
A process for determining the temperature of a human body fluid sample or food product sample comprising:
- (a) placing a sample, contained in a sample holder, a predetermined distance away from, and in the focal path of, an infrared temperature detecting means having a close focus means;
- and
- (b) detecting said temperature of said human body fluid sample or food product sample with said temperature detecting means without contacting the sample by measuring the infrared rays emitting from said sample, and reading the temperature on an L.E.D. display which is actuated by the infrared detecting means.
- said infrared detecting means having been calibrated to take into account the emissivity values of the said sample and sample holder whereby the reading on the L.E.D. display reflects the calibrated emissivity value.
A portable apparatus for determining the temperature of an individual human body fluid sample or an individual food product sample comprising:
- (a) a base means having attached thereto a support means for supporting a sample container, said container being adapted for holding said individual sample, in operable alignment with a means for measuring temperature and displaying the temperature;
- (b) said means for measuring temperature being an infrared detecting device which is operable for measuring the temperature of said human body fluid sample or food product sample within said sample container without contacting said sample within the sample container, said temperature measuring means being releasably attached to said base means;
- and
- (c) said individual sample container being removably disposed on said support means supported by said base and having means for adjusting the height of said sample in relation to the temperature measuring means, said sample container disposed a predetermined distance spaced apart from said temperature measuring means.
