Abstract: A temperature control system provides for the optimal management of patient temperature during a surgical procedure, such as those which require the patient to on bypass. The system employs a plurality of controllers as well as a plurality of temperature control means in order to provide optimal temperature control. In one configuration of the invention, controllers for each of the heat exchange devices may be interconnected using a data link. The connection may provide for a master/slave relationship wherein temperature sensors included in each system are employable as temperature feedback for initiating temperature changes. This device may be configured such that it operates in conjunction with another device or provides stand alone temperature control.

Abstract: A connector apparatus employable in a patient temperature control system includes a connection end which is employable for connecting to at least one other connector in the system. Includable in the connection end is an orientation device configured to align the connectors and provide for interconnection only at a predetermined orientation. The connector may be configured as either a male or female style connector and include one or more engagement devices or surfaces for engaging with another connector.

Abstract: A system and method provide for the interconnection of a medical fluid processing system with at least one patient temperature control pad positionable on a patient. Includable in the system is at least one connector interconnected and/or interconnectable to the medical fluid processing system and at least one connector interconnected and/or interconnectable to the at least one temperature control pad, wherein the connectors include an orientation device which provides for interconnection of the connectors at a predetermined orientation.

Abstract: An improved patient temperature exchange system and method is disclosed for use with one or more interconnectable patient contact pads. In one embodiment, the system includes a circulating pump for drawing fluid through the interconnected pad(s) under negative pressure, and for pumping the fluid through one of more heat exchange devices into a circulating reservoir. A make-up reservoir may be provided for gravity fluid flow into the circulating reservoir during the filling of the interconnectable pad(s) and for receiving fluid upon emptying of the interconnectable pad(s). During normal heating/cooling operations, the circulated fluid does not pass through the make-up reservoir, thereby yielding a highly responsive system. The make-up and circulatory reservoirs may be directly interconnected, with the make-up reservoir maintained at atmospheric pressure (e.g. via a non-spill vent).

Abstract: The present invention provides for rapid heat transfer with a tissue region of interest (24) by the direct contact of a circulated thermal exchange fluid with the tissue region of interest (24). The tissue region of interest is covered with an appropriately configured flexible membrane (28). A spacing structure maintains a spaced relation between an interior side (30) of the flexible membrane (28) and the tissue region of interest (24) to define a fluid circulation space (34) for fluid flow therebetween. Thermal exchange fluid is drawn into the fluid circulation space (34) though an inlet (60) in the flexible membrane and out of the fluid circulation space (34) through an outlet (64) in the flexible membrane (28) under negative or nearly negative gauge pressure. The fluid directly contacts the tissue region of interest (24), resulting in cooling/heating of the tissue region of interest (24).

Abstract: An extracorporeal blood perfusion system includes a disposable assembly and a control unit having a control interface region. The interface region includes pump assemblies for selective pumping of venous blood, arterial blood, cardioplegia solution, suctioned blood and blood removed from the left ventricle. Valve assemblies control the flow of fluids through the assembly and to/from the patient and sensors monitor various fluid parameters including temperature and pressure within the various fluid circuits. The user interface is a functional screen interface for effecting the operation of the control unit and valve assemblies. The screen interface may be a touch screen having objects that corresponds to the component interface region. The display may be selectively controlled to provide graphic depictions of disposable assembly components with corresponding narrative instructions.
