Abstract
Disclosed herein is a luer connector which exhibits an improved engagement force, in comparison to a standard luer connector, when a fluid contaminant is present between the contact surfaces of mated luer fitments. The luer connector of the present invention comprises a textured contact surface which is adapted to trap or channel fluid contaminants away from the contact surfaces of mated luer fitments. Also disclosed herein is a method of making a luer connector with a textured contact surface.
Claims10
A syringe, comprising:
- a hollow barrel with an open proximal end and a conical distal tip;
- a plunger assembly inserted into the open proximal end, the plunger assembly and the hollow barrel defining an internal variable volume chamber for retaining fluid;
- wherein the exterior surface of the tip is provided with a non-coated texture, such that the force required to disengage the tip from a conically-shaped female fitment when a fluid is present between the tip and the fitment is equal to or greater than the force required to disengage the tip and the fitment when the tip and the fitment are dry, and the force required to disengage the tip from the female fitment in the dry state does not exceed the force required to disengage an identically dimensioned coated tip from the female fitment in the dry state.
