ABSTRACT:
The device is primarily adapted for use in hospitals and comprises a housing having a front window through which a digital display of sensed temperature is observed. The housing may receive one of preferably two probe holsters one of which has associated therewith a probe for oral use and the other of which has a probe for rectal use. Each probe holster is elongated in shape and has a passage for receiving a probe with the probe being fixedly wired into the holster so that the probe cannot be swapped between holsters. A holder is mounted on the top of the device and receives a cartridge of probe covers which are locked into the holder but are easily removed upon insertion of the probe into an individual cover. The holsters and associated probes are constructed to be autoclavable and gas sterilizable. The device is normally stored on a platform through which the batteries in the device are recharged between use of the device. The probe is of improved design and employs a thermistor sensor. The probe construction provides improved response time in sensing temperatures. The device of the present invention may be operated in essentially two different modes. For normal use the device is operable for a predetermined period of time to detect a peak temperature sensed at the end of the time period. In an alternate mode of operation the device can be operated continuously with continuous updating of the temperature sensed.
