Principles of Operation: 3.3 Functional Description
3.2.3 Temperature (Model 200 and 400)
The ProCare Monitor uses Alaris Turbo Temp technology to measure patient
temperature. The Turbo Temp probe contains a heating element that pre-
heats the probe to reduce determination time. The heating function is
controlled by the Main Board. The Turbo Temp probe also contains a
thermistor that indicates the temperature. When the probe is attached to the
temperature connector and patient, the signal generated by the thermistor is
routed to the Main Board. The Main Board converts the thermistor signal
along with status information (i.e ORAL or RECTAL probe indicators) to a
DIGITAL signal. The Main Board then processes the DIGITAL signal and
displays the patient temperature on the UI Board and printer in Celsius or
Fahrenheit.
3.2.4 Host Communication Port
The Host Comm Port is used to interface the ProCare Monitor with other
electronic devices (a central nurse's station or remote alarm device.) Signals
can be sent to the
ProCare Monitor to initiate blood pressure determinations
and other functions. Patient data can also be retrieved through this port. For
further information, reference the Dinamap
ProCare Series Host
Communication manual.
