Abstract: A disinfection cap is described for connection to a medical connector, the disinfection cap includes a housing having a top wall and sidewall forming a cavity, an open cell foam structure disposed within the cavity and a closed cell foam structure disposed against the open cell foam structure, the closed cell foam structure having an interference fit between the closed cell foam structure and the inner surface of the housing. The closed cell foam structure may have a polygonal or star shape, wherein fluid can flow through a gap formed between the closed cell foam structure and the inner surface of the cavity. The open cell foam structure may be impregnated with disinfectant, whereby compression of the open cell foam structure causes excretion of the disinfectant upon insertion of a luer connector.

Abstract: A disinfection cap is described for connection to a medical connector, the disinfection cap includes a housing having a top wall and sidewall forming a cavity, disinfectant or antimicrobial agent and a ball disposed within the cavity. An outer surface of the housing includes a thread sufficient to interlock with a mating feature of a threaded connector, or more specifically a male luer connector. The cap may also include a peelable seal to prevent the disinfectant or the antimicrobial agent from exiting the cavity. The cavity of the cap may also include one or more ribs disposed on the inner surface of the cavity to retain the ball in the cavity, forming a flow channel as the ball is depressed further into the cavity. An exterior sidewall surface of the housing may include a plurality of grip members.

Abstract: A disinfection cap is described for connection to a medical connector; the disinfection cap includes a housing having a top wall and sidewall forming a cavity. In one or more embodiments, a retention rod forming a fluid reservoir is disposed within the cavity for retaining disinfectant. In one or more embodiments, a corrugated capsule is disposed within the cavity for retaining disinfectant. Pressure buildup within the cavity due to insertion of a luer connector causes expulsion of disinfectant, thereby disinfecting the luer connector.
