COLD PLATE DESIGN IN HEAT EXCHANGER FOR INTRAVASCULAR TEMPERATURE MANAGEMENT CATHETER AND/OR HEAT EXCHANGE PAD

摘要

Cold plates through which refrigerant flows define a slot between them that can receive a cassette through which sterile working fluid with a relatively low flow rate flows from an intravascular beat exchange catheter or external pad. The slot may have bulge cavities along the edges to permit the membrane of the cassette to expand and thus establish fluid supply and return passageways.

主权项

1. An apparatus comprising;
a plate assembly having a cassette slot configured to receive a membrane assembly of a cassette, with the membrane assembly being configured for containing working fluid from an intravascular heat exchange catheter or heat exchange pad, the plate assembly also including rail receptacles straddling respective sides of the slot and configured for receiving respective side rails of the cassette, wherein at least a first bulge cavity formed inboard of a first one of the rail receptacles, the first bulge cavity having a width at its widest point that is greater than a width of the slot.
