A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip. The fluid space within the valve automatically and reversibly increases upon insertion of the medical implement into the cavity and decreases upon withdrawal of the medical implement, such that a positive flow from the valve toward the catheter tip is effected upon withdrawal of the medical implement, thereby preventing a flow of blood from a patient into the catheter when the medical implement is removed from the valve.

1. A medical valve for controlling the flow of fluid between a medical implement and a catheter tip of a catheter in fluid communication with said valve, said valve comprising a body having a cavity with an outlet adapted to be connected in fluid communication with a catheter tip and an opening adapted to receive a medical implement, and a seal positioned within said body and movable between a first position in which fluid flow is permitted through said opening and a second position in which said seal obstructs fluid flow through said opening, said cavity including a first fluid space open to said outlet when said seal is in said first position and a second smaller space open to said outlet when said seal is in said second position.
