1. A medical valve comprising: a body including a wall structure defining an internal cavity having an inside and an outside, said body also having a proximal end and a distal end, said proximal end having an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through said delivery end, said body having a fluid escape space in said wall structure; a spike having a tip, at least one hole located at or near said tip, and a passageway in communication with the hole that allows fluid to flow through said spike; and a 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, at least a portion of said seal engaging said wall of said body, wherein said fluid escape space extends past said portion of said seal engaging said body and is in fluid communication with the outside of said cavity when said seal is in said compressed state. 2. The medical valve of Claim 1, wherein said fluid escape space comprises at least one groove. 3. The medical valve of Claim 2, wherein said groove is located in said wall structure of said body and terminates at the proximal end of said body. 4. The medical valve of Claim 1, wherein said fluid escape space comprises a channel through said body, said channel located distal said opening in the proximal end of said body. 5. A method of transferring a first fluid through a medical valve, said valve comprising a body with an internal cavity having an inside and an outside, said cavity also having a proximal end and a distal end, said proximal end having an opening sufficiently large to receive a delivery end of a medical implement which transfers fluid through said delivery end, and a seal within the cavity of said body, said seal having a portion engaging said wall of said body, said valve containing a second fluid in said cavity between said seal and said body, said method comprising the steps of: a. inserting the tip of a medical implement into the opening in the proximal end of said body; b. compressing said seal in the distal direction by applying a force to the medical implement; c. expelling said second fluid from said cavity of said body to a point outside said cavity through a fluid escape space contained in said body of said valve; and d. transferring said first fluid through said medical valve. 6. The method of Claim 5, wherein step (c) comprises expelling said second fluid through a groove in said wall structure of said body. 7. The method of Claim 6, wherein said groove extends distally from the proximal end of said body. 8. The method of Claim 5, wherein step (c) comprises expelling said second fluid through a channel in said wall structure of said body. 9. The method of Claim 8, wherein said channel is located distal the proximal end of said body. |
