Disinfection cap
A disinfection cap is described for connection to a medical connector, the disinfection cap including a housing having a top wall and sidewall forming a cavity, a blockage feature disposed on the top wall of the cavity, the blockage feature for fluidly blocking a hub of a luer connector, disinfectant or antimicrobial agent disposed within an open cell foam structure within the cavity. The open cell foam structure releasing the disinfectant or antimicrobial agent as the open cell foam structure is depressed by the hub of the luer connector.
1 . A disinfection cap comprising:
a housing;
a top wall having an aperture extending partially into the housing;
a cylindrical sidewall having an inner surface defining a cavity,
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;
an umbrella stopper including a stem at least partially disposed into the aperture of the top wall, the umbrella stopper further including a fanned barrier configured as a blockage feature for fluidly blocking a hub of a medical device, the fanned barrier creating a liquid tight seal with the inner surface of the cylindrical sidewall; and,
a fluid releasably retained within the cavity between the fanned barrier of the umbrella stopper, the top wall, and the cylindrical sidewall, wherein the hub of said luer connector is received within said inner surface of said cavity and wherein the fanned barrier deforms when moved against the hub, thereby releasing the fluid.
2 . The disinfection cap of claim 1 , wherein the umbrella stopper further includes a rounded or chamfered end, the rounded or chamfered end configured to fluidly block the hub of the luer connector.
3 . The disinfection cap of claim 1 , wherein the fanned barrier is at a right angle to the stem.
4 . The disinfection cap of claim 1 , wherein the fanned barrier is at an obtuse angle to the stem.
5 . The disinfection cap of claim 1 , wherein the stem is integrally formed into the aperture.
6 . The disinfection cap of claim 1 , wherein the stem is non-removable.
7 . The disinfection cap of claim 1 , wherein the stem is removably assembled with a threaded connection, press-fit connection, adhesive connection or a combination thereof.
8 . The disinfection cap of claim 1 , wherein the diameter of the fanned barrier is equal to the diameter of the cavity.
9 . The disinfection cap of claim 1 , wherein the fluid is disposed within the chamber further defined by the fanned barrier and an upper portion of the cavity, the upper portion of the cavity is defined by the top wall and an upper portion of the cylindrical sidewall.
10 . The disinfection cap of claim 1 , wherein the fanned barrier is elastically deformable into a lumen of a luer connector creating a liquid tight seal while the elastic deformation of the fanned barrier interrupts the liquid tight seal of the fanned barrier and the cavity, releasing the fluid which disinfects the hub and the periphery of the luer connector.
11 . The disinfection cap of claim 1 , wherein the fanned barrier is made of a deformable elastomeric material.
12 . The disinfection cap of claim 11 , wherein the deformable elastomeric material is rubber or TPE.
13 . The disinfection cap of claim 1 , wherein the fanned barrier includes a plurality of spines disposed radially from the stem.
