Abstract
A stopcock with a locking connector protective assembly for selectively controlling the passage of sterile medicinal fluids from a plurality of sources and comprising a body having a plurality of input arms with male or female locking connector tips, an output arm with a male locking connector tip, a rotor located inside the body and having a handle and rotatable about an axis in the body and having a rotor lumen and having channels or holes that may be aligned with the arm lumens as indicated by pointers. A self-sealing injection port is provided which covers the rotor lumen. A locking connector protective assembly is mounted on the input arms to prevent touch contamination and may be retrofitted to current stopcocks, and retained by the locking connector tip. A telescoping resilient coil variably expands to enclose the locking connector tip when the tip is not in use and retracts sufficiently to allow access to the locking connector tip for connections to a complementary locking connector tip. A rim at the proximal end of the coil has resilient locking tabs permitting installation over a locking connector tip flange, but resisting removal therefrom, and a lid that may be flipped off the rim for access to the locking connector tip and which is retained by a flexible lid retainer link connected to the rim.
