Temperature Controller
The temperature controller uses input from the patient’s temperature probe and
the operator-selected patient temperature setpoint to regulate the coolant
temperature of the recirculating chiller. The temperature controller constantly
adjusts the coolant temperature by means of a closed-loop control system. The
operator enters a setpoint that represents the patient’s target temperature. The
controller cools or heats the coolant, in a range between 0º and 42º C (32º and
107.6º F) to optimally achieve and maintain the target temperature. The controller
constantly displays the measured patient temperature and the target
temperature.
An optional mode can command the controller to approach the target
temperature at a user-selected rate.
Temperature Probe Connectors
The front of the System console features two connectors, labeled “T1” and “T2”
which are used for connection to patient temperature probes. The primary patient
temperature probe is plugged into connector T1. The secondary probe is plugged
into connector T2.
Figure 2-4. Temperature Probe Connectors.
Pump
Sterile saline solution is circulated through the heat exchanger coil and the
catheter by a high-performance, compact roller pump. It pumps by peristaltic
action on the tubing installed in the pump head. The pump rotation speed is
accurately controlled by an electronic speed control system. The pump flow rate
can be selected by the user.
