Safety luer connection
View Patent ↗A connection device has a male connector and a female connector. The female connector will only accommodate the dedicated male connector, thereby prohibiting a misconnection with the wrong male connector. In certain embodiments, a member prohibits male connectors, other than a dedicated male connector, from being inserted into the female connector. In certain other embodiments, a post prohibits male connectors, other than a dedicated male connector including a slot, from being inserted into the female connector. In still certain other embodiments, a series of prongs in the male connector and corresponding grooves in the female connector ensure the proper connection. Once the male connector is inserted and secured within the female connector, a fluid-tight seal is formed between the male connector and the female connector.
1. A connection device comprising:
a male connector comprising a body with a distal end and a proximal end, and a projection from the body having an external conical surface with a Luer taper and an opening located at a distal end of the projection, the opening in fluid communication with a fluid passageway located within the male connector body, the projection having a length L 1 ; and
a female connector comprising a body with a distal end and a proximal end and an internal fluid passageway having an internal conical surface with a Luer taper which sealingly mates with the external conical surface of the male connector and a member projecting into the internal fluid passageway at a point intermediate to a proximal end and a distal end of the internal conical surface, the member positioned a length L 2 from the proximal end of the female connector and blocking insertion of the projection past the member, with L 1 =L 2 , such that an external conical surface of a male Luer connector with a projection having a length greater than the length L 1 cannot sealingly mate with the internal conical surface of the female connector;
wherein the member is a rod-shaped bar which is positioned within and across the fluid passageway of the female connector to span the fluid passageway of the female connector.
2. The connection device of claim 1 , wherein the projection extends from the body a distance less than the distal end of the body.
