A male luer connector device that attaches to any standard female luer valve to open a flow channel between the two luers. The male luer is comprised of a tubular housing element, a resilient member contained within the housing and extending within an inner tubular portion defined in the housing, a resilient member that extends within the inner tubular portion of the housing, and a valve member attached to the resilient member that seals the tubular portion. When the male luer is engaged with any standard female luer, a female luer connector device drives the resilient member of the male luer into a compressed position to open the forward end of the male luer and permit liquid flow between the luers.

A male luer for connection with a female luer valve having a contact surface, the male luer comprising:a housing having a forward end and a rearward end; and disposed within the housing: a first tubular member positioned within the housing and having a forward end and a rearward end; a resilient member with forward and rearward ends disposed coaxially with the first tubular member, the resilient member being movable between a compressed, retracted position and an extended position; and a valve member disposed at the forward end of the resilient member for openable closure of the male luer during such movement; wherein when the male luer is inserted into the female luer the contact surface of the female luer motivates the resilient member into the compressed position to open the forward end of the male luer and permit liquid flow through and between the luers, with the liquid transiting the male luer traveling in a generally axial path through the tubular conduit of the male luer to or from the female luer. 12. The male luer as claimed in claim 11, wherein the housing is generally cylindrical and defines an internal chamber and contains threads on its surface for engaging complementary threads on the female luer connector.13. The male luer as claimed in claim 11 wherein the resilient member is disposed internally of the first tubular member with the rearward ends of both in contact with each other and with a portion of the housing, such that the first tubular member secures the rearward end of resilient member against movement.14. The male luer as claimed in claim 13 wherein the first tubular member also includes means to guide movement of the resilient member during compression and decompression of the latter.15. The male luer as claimed in claim 11, wherein the first tubular member is comprised of rigid molded material.16. The male luer as claimed in claim 11, wherein the resilient member and the valve member are formed integrally.17. The male luer as claimed in claim 16, wherein the resilient member and the valve member are made of elastomeric material.18. The male luer as claimed in claim 11 wherein the first tubular member is disposed internally of the resilient member and acts to guide movement of the resilient member upon compression or decompression.19. The male luer as claimed in claim 11 further comprising a second tubular member wherein the resilient member is disposed internally of the second tubular member with the rearward ends of both in contact with each other and with a portion of the housing, such that the second tubular member secures the rearward end of resilient member against movement.20. The male luer as claimed in claim 11 further comprising the resilient member being responsive to its contact with the contact surface of the female luer during engagement between the luers, responsiveness comprising compression of the resilient member effecting opening of the male luer to permit fluid flow between and through the luers.21.
