Product Description
Fluid Ouput
Temperature Measurement
The Bard CritiCore System consists of a fluid output and core temperature
monitor, a disposable collection system, and disposable temperature probes
(temperature-sensing Foley catheters).
Note:
Consult the Operators Manual for details on all Bard CritiCore
Monitor functions.

The Bard CritiCore Monitor electronically measures fluid output volume
utilizing ultrasound technology.
During operation, the disposable container
rests within the Monitor and sits on top of a silicone rubber transducer cap.
Underneath the silicone rubber cap is the transducer element, which will
periodically transmit a controlled burst of ultrasonic energy up through the
container.
Ultrasonic energy will travel through the fluid and reflect back
towards the transducer at the fluid/air interface. The transducer also
functions as receiver, detecting the return of the transmitted burst. The
microcontroller within the CritiCore Monitor will measure the time the energy
burst took to make the round-trip. This information is then converted into
container volume.
Bladder Temperature is measured by a temperature-sensing Foley catheter.
The temperature sensor integral to the disposable catheter is a "400-Series"
thermistor. As the Bladder Temperature changes, so does the resistance of
the thermistor. Sensitive electronics in the Bard CritiCore Monitor will detect
any change in the resistance of the thermistor.
The resistive vaiue of the
400-Series thermistor is converted into a corresponding relative temperature
reading.
