Abstract:
1. A system for adjusting the temperature of a patient, comprising: a primary fluid circuit, the circuit including: primary fluid circuit lines connecting the primary fluid circuit pump to the heater/cooler such that a continuous flow path for circulating primary fluid from the pump to the heater/cooler and back to the heater/cooler is formed; access points in the primary fluid circuit, the access points fluidly connecting the primary fluid circuit to a primary fluid circuit side of a heat exchanger, the heat exchanger also having a secondary fluid circuit side; a heat exchange catheter insertable within a patient, the catheter configured to increase, decrease or maintain the temperature of the patient; a secondary fluid circuit for flowing secondary fluid through the secondary circuit side of the heat exchanger and the heat exchange catheter, the secondary fluid circuit including a secondary fluid circuit pump for flowing a secondary heat exchange fluid through the secondary fluid circuit to the heat exchange catheter and back through the secondary fluid circuit to the secondary fluid pump; at least one fluid sensor configured to provide a signal representative of a temperature of the primary or secondary fluid circuit; a patient sensor configured to provide a signal representative of a temperature of the patient; a controller configured to receive the signals from the patient sensor and the primary fluid sensor and being responsive to the signals to control the heater/cooler to adjust the temperature of the fluid flowing within the fluid circuits.
