2.3 Temperature Monitoring

Figure 2-18. Intracavitary temperature sensor
When using the sensor for monitoring the central body temperature, it is introduced into the se-
lected cavity, and to facilitate insertion, the surface of the sensor and the cable should be lubri-
cated for the required length (sterile glycerin or vaseline oil).
The sensor is supplied non-sterile. It is necessary to sterilize it before appli-
cation (see it. 2.3.4).
In addition to reusable temperature sensors, device also can be used with the disposable tem-
perature sensors of a universal type, having reduced dimensions and rigidity of the wire, which
can in some cases be important, for example, for monitoring of newborn patients.
The sensor has also a pad that provides not only fixation of the sensor to the patient's body, but
also thermal insulation of the sensor from the external environment
For connection of the disposable temperature sensors, the device must be equipped with the
TESM.096018 temperature sensor adapter.
2.3.3. Test of Measurement Accuracy of the Temperature Sensors
The applied reusable temperature sensors do not require calibration or adjustment during the
entire service life, including their replacement. If there are any doubts about their accuracy, then
it can be easily checked by comparison with a control (known good) thermometer.
To carry out the test, connect the tested sensor to the device and place it together with the con-
trol thermometer into the armpit for a few minutes until the temperature readings of the sensor
(in the device temperature window) and the control thermometer are completely stabilized. Then
compare the sensor readings with the readings of the control thermometer.
When using a usual medical thermometer as a reference, it should be borne
in mind that its measurement accuracy is low and can be several tenths of a
degree, so the difference between the test results within these limits is not
an unambiguous evidence of sensor malfunction.
A reliable conclusion can be made only when using a special high-precision
thermometer for the reference.
2.3.4. Disinfection and Sterilization of the Temperature Sensors
Disinfection of the reusable surface sensor is carried out in accordance with the requirements of
MU-287-113 by wiping them with a 3% solution of hydrogen peroxide with the addition of 0.5%
