Closed fluid transfer system with syringe adapter

摘要

A closed fluid transfer system for fluidly interconnecting a syringe to any one of a patient I.V. set, a vial and an I.V. bag, is provided and includes a housing defining an open distal end and an open proximal end, a base supported in the open proximal end of the housing and including a syringe adapter luer connector, a collar slidably and rotatably supported in the housing, the collar defining a longitudinal opening therethrough, a shuttle slidably extending through longitudinal opening of the collar, the shuttle defining a shuttle lumen extending longitudinally therethrough, a barrel supported on and extending over a distal end of the shuttle, a biasing member interposed between the collar and the shuttle for urging the collar away from the shuttle, and a seal interposed between the shuttle and the barrel, wherein the seal extends across the shuttle lumen and the central opening of the barrel.

主权项

1. A syringe adapter for a closed fluid transfer system, the syringe adapter including:
a housing defining an open distal end and an open proximal end, the housing defining a pair of opposed longitudinally extending slots opening from the open distal end of the housing, the housing including a pair of opposed longitudinally extending ribs projecting from an inner surface thereof; a base supported in the open proximal end of the housing and including a syringe adapter luer connector; a collar slidably and rotatably supported in the housing, the collar defining a longitudinal opening therethrough, the collar defining a pair of opposed L-shaped tracks formed in an outer surface thereof and configured to receive a respective longitudinally extending rib therein, the collar defines a pair of opposed helical tracks opening from a distal surface of the collar, the opposed helical tracks being aligned with a respective slot of the housing when the collar is in a distal-most position; a shuttle slidably extending through longitudinal opening of the collar, the shuttle defining a shuttle lumen extending longitudinally therethrough; a barrel supported on and extending over a distal end of the shuttle, the barrel defining a central opening aligned with the shuttle lumen; a biasing member interposed between the collar and the shuttle for urging the collar away from the shuttle; and a seal interposed between the shuttle and the barrel, wherein the seal extends across the shuttle lumen and the central opening of the barrel.
