Abstract:

The present invention provides an improved transfer set for use in an automated compounding device. The transfer set comprises a plurality of fluid conduits, each fluid conduit including a first section and a second section, the first and second sections being coupled together in fluid communication by a coupler. A housing is provided for receiving at least a portion of the fluid conduits and the coupler. The housing defines separate channels for receiving a portion of the second section of each fluid conduit. The channels extend for a sufficient distance so that at least substantially an entire length of the second section that is located in the housing is located in a channel thereby securing the fluid conduits in place in the housing. An improved method for making a transfer set is also provided.
