초록 ▼

A medical connector for manually connecting a fluid conveying conduit that is in fluid communications with a patient\s vasculature and having a junction terminal at an end thereof to a fluid conduit for administration of fluid to the patient. The connector is formed of two components. The first component includes a cannula hub to which a cannula is mounted, a base extending from the hub and fingers extending from the base. The second component is a collar including a support and bars extending therefrom. The collar is manually slidable along the first component in the direction the cannula extends between a retracted position and a locking position. The bars engage the fingers to flex into engagement with the junction terminal. The bars are elastically deformable to provide a spring force for locking the fingers on the junction terminal.

A medical connector for connecting a secondary intravenous tubing system having an open end to a primary intravenous tubing system having a junction terminal, the junction terminal including a tube defining an axis having an outer axial surface and a bore extending to a junction end, the junction end being occluded by an elastic sealing member, the connector comprising: a. a base having a first open end and a lumen extending through said base, said base having means for connecting to said open end of said secondary tubing, b. a cannula extending axially from said base, said lumen extending through said cannula from said base, c. at least two cantilevered fingers extending axially from said base and about said cannula, at least the distal portions of said fingers being moveable from (1) a first, resting position wherein said junction end can be received between said fingers and said cannula can penetrate said sealing member so that said lumen of said cannula is in fluid communication with said bore, to (2) a second, flexed position wherein said junction terminal is received by said fingers so that displacement of said junction terminal from between said fingers when inadvertent retraction force is applied to one said primary system and said secondary system is substantially prevented, d. a collar slidable along said connector from, (1) a retracted position allowing said fingers to rest in said first position to, (2) an advanced position, said collar engaging said fingers to flex said fingers from said first position to said second position when said collar is moved from said retracted position to said advanced position, e. each said finger having a cam defined thereon, said collar engaging said cam upon displacement of said collar toward said advanced position, engagement by said collar deflecting at least the distal portion of the respective finger toward said flexed position.
