Abstract

See full text

A transfer set assembly for transferring fluids between a first container, such as a conventional medical vial, having a sealed open end and a second container such as a conventional IV infusion bag. The transfer set includes a collar having a proximate tubular end portion for securement to the container, a needle cannula and holder assembly, which is telescopically received in a distal tubular portion of the collar, and a closure including a tubular body portion having an open proximate end which is telescopically received over the needle cannula and holder assembly and the distal tubular portion of the collar, a closed distal end portion and an inner tubular portion which is integral with the closed distal end. The inner tubular portion includes a free end having spiral camming surfaces which mate with spiral camping surfaces on the inside surface of the tubular distal portion of the needle cannula holder. The tubular body portion of the closure includes lateral slots which receive projections on the collar and contiguous camming surface which extends toward the proximate open end of the closure. Rotation of the closure relative to the collar first drives the mating spiral camming surfaces of the closure and holder together, thereby driving the needle cannula and holder assembly axially to pierce the seal of the container. Continued rotation of the closure drives the projections on the collar against the contiguous angled camming surface, driving the closure from the collar and providing access to the needle cannula for transfer of fluids to a second container, such as an IV infusion bag.
