Title:
HEAT EXCHANGER CONNECTOR ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2010/107472
Kind Code:
A3
Abstract:
A connector assembly for a heat exchanger has a fitting and a mount to which the fitting couples. The fitting has an elongate body having a proximal portion and a distal portion. At the proximal portion there is a crossbar, and at the distal portion there are an inlet and an outlet that protrude away from the body. Two wings extend from the body in a direction opposite to that of the inlet and outlet. There is formed on each of the wings a locking protrusion. The mount has a top portion where there is a groove dimensioned to accept the crossbar of the fitting. A longitudinal channel is formed orthogonal to the groove in the mount. Two sidewalls extend from the mount each for accepting a corresponding one of the wings, when the fitting is coupled to the mount. Apertures are provided at the sidewalls to engage the protrusion at the wings so that, once the fitting is coupled to the mount, it is secured thereto, until a force is exerted to compress the wings towards each other to disengage the protrusions from the apertures. To couple the fitting to the mount, a user first positions the crossbar of the fitting onto the groove of the mount, with the body of the fitting at an angle relative to the mount. With the crossbar resting on the groove, a pivot point is established between the fitting and the mount, so that the body of the fitting can be pivotally positioned within the channel of the mount. At that time the inlet and outlet of the fitting are mated to an output port and an input port, respectively, of the mount; and the protrusions at the wings of the fitting are engaged to the apertures at the sidewalls of the mount. An infusate line and a heat exchanger are connected to the proximal end and distal end, respectively, of the fitting.
