A medical valve has a body which includes a wall structure defining an internal cavity having a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the delivery end. The valve also has a spike with a tip contained within the cavity and at least one hole located distal the tip. The spike has a passageway in communication with the hole that allows fluid to flow through the spike. The valve also has a resilient seal in the cavity which surrounds the spike. The seal is adapted to be moved into a compressed state upon insertion of the tip of the medical implement into the opening. The seal is sufficiently resilient to return to a decompressed state upon removal of the tip of the medical implement from the opening. In Addition, the seal has at least two tires in contact with the spike proximal the hole, preventing the flow of fluid through the valve when the seal is in the decompressed state.

[ What is claimed is:] [1.] A medical valve comprising:a body including a wall structure defining an internal cavity, said body having a proximal end and a distal end, said proximal having an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through said delivery end;a spike having a tip contained within said cavity, said spike having a first hole located distal said tip, a second hole located distal said first hole, and a passageway in communication with said first and second holes that allows fluid to flow through said spike; anda resilient seal in said cavity surrounding said spike, said seal adapted to be moved into a compressed state upon insertion of the tip of the medical implement into said opening, said seal being sufficiently resilient to return to a decompressed state upon removal of the tip of the medical implement from said opening, said seal in the decompressed state being in contact with said spike in at least two spaced-apart points along said spike proximal said first hole preventing flow of the fluid through said valve when said seal is in a decompressed state.
