Abstract
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.
Claims39
A male luer comprising:
- a tubular conduit having a forward end;
- a resilient member extending coaxially with the tubular conduit opposite rearward and forward ends;
- and
- a valve member at the forward end of the resilient member, the valve member openably sealing the forward end of the tubular conduit;
- such that when the male luer is inserted into a female luer, contact with the female luer drives the resilient member into a compressed position to open the valve member of the male luer and permit flow from one luer to another, 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.
The male luer as claimed in clam 3, wherein the resilient member is a spring or is of elastomeric material.
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.
A male luer comprising:
- a housing;
- a resilient member with first and second ends that can be elastically displaced that is contained within the housing;
- a tubular member with a forward end and a rearward end contained between the housing at a position located coaxially between the housing and the resilient member wherein the forward end of the tubular member contains a recess that creates a necked area;
- a valve member abutting the resilient member and sealing the forward end of the tubular member, the resilient member being movable between an extended position in which the valve member is in sealing engagement with the forward end of the tubular member, and a retracted position in which the valve member is refracted rearwardly form the forward end;
- such that when the male luer is inserted into a female luer the female luer drives the resilient member into a compressed position to open the forward end of the male luer and permit flow from one luer to another whereby liquid exiting the male luer travels in a generally linear path through the tubular member of the male luer and enters the female luer.
