Abstract

An improved protective cap and method for capping medical male luer fittings is provided. The protective cap may include inner and intermediate annular members extending from an end wall and defining a slot therebetween. At least one and preferably a plurality of depressible members project from an outer surface of the inner annular member, wherein the depressible member(s) conforms to the internal threads of a male luer fitting upon interconnection. For such purposes, the depressible member(s) may comprise a resilient material, e.g. most preferably having a modulus of elasticity of between about 5000 psi and 20000 psi. Each depressible member may be of an arcuate configuration in cross-section to present a convex surface for depressible engagement by the collar of a male luer fitting when positioned in the annular slot. The protective cap may be readily employed in automated capping/uncapping procedures via direct linear advancement/retraction relative to a male luer fitting. The protective cap may also be readily rotated onto and off of a male luer fitting. The protective cap and associated methodologies are particularly apt for use in connection with syringes, including automated procedures for pre-filling disposable syringes with medical liquids.
