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.
Claims13
A disinfection cap having a housing comprising:
- a cylindrical sidewall having an inner surface defining a cavity and a top wall,
- an open bottom formed by the cylindrical sidewall with an opening to the cavity within said housing for receiving a hub of a luer connector;
- a retention rod disposed within the cavity, the retention rod having a proximal flange, a distal flange and an elongated rod between the proximal flange and distal flange, the distal flange of the retention rod abutting the top wall of the cavity, wherein a diameter of the proximal flange of the retention rod is equal to or slightly larger than a diameter of a proximal portion of the cavity, configured to have an interference fit sufficient to create a fluid seal between the proximal flange of the retention rod and the proximal portion of the cavity;
- a fluid reservoir defined between the inner surface of the housing, the proximal flange of the retention rod and the distal flange of the retention rod;
- and,
- a disinfectant disposed within the fluid reservoir, the disinfectant being retained within the fluid reservoir in an initial state, wherein the hub of said luer connector is received within said inner surface of said cavity.
