Abstract
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.
Claims8
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 cavity formed inboard of a first one of the rail receptacles, the first cavity having a width at its widest point that is greater than a width of the slot, wherein when the cassette is engaged with the apparatus with the membrane assembly disposed in the slot and the side rails of the cassette disposed in the rail receptacles, a first portion of the membrane assembly that is inboard of a side rail of the cassette can expand into the first cavity when the membrane assembly is filled with working fluid to thereby establish an enlarged fluid passageway along a vertical side edge of the membrane assembly.
