Abstract: The temperature regulating device of the instant invention accurately regulates the temperature of a fluid to be sent through a conduit for either warming or cooling an infusate that is to be provided to a patient. The heater/cooler that is used for regulating the temperature of the fluid, and the fluid itself, are continuously monitored by a number of sensors, which provide feedback signals to a processor controller, to ensure that the temperature of the fluid is maintained at a desired temperature. The fluid is circulated by a pump which operation is also continuously monitored. A special connector assembly provides the inlet/outlet connection between the device and the fluid conduit. The connector assembly is constructed such that the system would operate only when the connector of the fluid conduit is correctly mated thereto.

Abstract: A disposable manifold and valve for fluid processing are claimed in which a manifold provides a plurality of sterile paths for directing the flow of fluids. A rotatable valve employs a cam to control the flow of fluids through the manifold. The valve and manifold system are suited for the processing of blood and particularly for the washing of shed blood retrieved during surgery.
