SURGICAL FLUID TRANSFER APPARATUS

摘要

A surgical fluid transfer apparatus includes a hub defining a longitudinal axis and an internal chamber. An elongated member extends from the hub and defines a longitudinal conduit. A closure valve is disposed within the internal chamber. The closure valve is adapted for movement between a first position substantially sealing the internal chamber to prevent passage of fluids and a second position establishing a fluid passage within the hub to permit passage of fluids therethrough. The closure valve includes a valve housing having inner wall portions defining a general tapered internal bore and a generally tapered seal member at least partially disposed within the tapered internal bore of the valve housing. The seal member has an open condition permitting passage of an access instrument through the closure valve and into the longitudinal conduit of the elongated member and a closed condition in the absence of the access instrument.
