Abstract:
1. A method of transferring fluid from a first medical implement to a second medical implement, comprising: connecting a medical valve to a first medical implement, wherein the valve comprises a body including a wall structure defining an internal cavity having a proximal end and a distal end, said proximal end having an opening sufficiently large to receive a delivery end of a second medical implement, said cavity further including a rigid fluid conduit, and a resilient seal element having a proximal end and a distal end and adapted to be moved distally in the cavity from a first position to a second position upon insertion of the delivery end of the medical implement into the opening, the seal element moving proximally in the cavity and returning to the first position upon removal of the delivery end from the opening, the seal element in the first position having a section that fills essentially completely a portion of the cavity adjacent the opening, the seal element section contacting the wall structure near the opening to obstruct fluid flow through the opening, and in the second position the seal element section being located in the cavity distal the opening, the seal element having an orifice at the proximal end thereof, wherein the seal element has at least one substantially horizontal groove to facilitate the movement of the seal element and the rigid fluid conduit is located at least partially within the seal element; inserting the delivery end of the second medical implement into the opening; and pushing the delivery end into the cavity to move the seal element to the second position to allow fluid to flow from the medical implement through the valve and into the first medical implement.
