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.
