Universal disinfecting cap
A device for connection to a medical connector, the device includes a cap body, a coupling cylinder adapted to engage with a male luer connector and a female luer connector, a bulb compartment filled with air, a reagent compartment filled with disinfectant or an antimicrobial reagent, and a passageway connecting the bulb compartment to the reagent compartment. The reagent compartment includes an exterior wall surface, an interior wall surface, an array of resealable pores densely integrated throughout the exterior wall surface and the interior wall surface of the reagent compartment, and a distal tip. The passageway may be positioned in an aperture of the proximal wall of the cap body. The coupling cylinder may include an O-ring.
1. A device for connection to a medical connector, the device comprising:
a cap body comprising a side wall having an outside surface and an inside surface, an open distal end, and a proximal end including a proximal wall, the proximal wall having an aperture, the side wall having a length extending from the proximal end to the open distal end, the open distal end defining an end face;
a coupling cylinder concentrically placed within the cap body and having a side wall with an inner surface that mates to an outer threaded surface of a female connector or a hemodialysis connector, an outer surface that mates to a threaded surface of a collar on a male connector, a distal end and a proximal end;
a bulb compartment protruding above the cap body and filled with air;
a reagent compartment surrounded by the coupling cylinder and connected to the bulb compartment, the reagent compartment having a boundary sidewall defining a chamber containing a disinfectant or antimicrobial agent, the boundary sidewall of the reagent compartment having an exterior wall surface, an interior wall surface, an array of resealable pores densely integrated and embedded in a polymer matrix of the exterior wall surface and the interior wall surface of the reagent compartment, and a distal tip; and
a passageway connecting the bulb compartment to the reagent compartment, the passageway positioned in the aperture of the proximal wall.
2. The device of claim 1 , wherein the distal end of the coupling cylinder includes an O-ring.
3. The device of claim 2 , wherein the O-ring is made of an elastomeric material.
4. The device of claim 1 , wherein the side wall of the coupling cylinder includes one or more leaf springs.
5. The device of claim 1 , wherein the open distal end of the cap body is situated on approximately a same horizontal plane P as the distal tip of the reagent compartment in an initial state.
6. The device of claim 1 , wherein when a female luer connector or a male luer connector is engaged to the device, the reagent compartment is compressed and retracts towards the proximal wall.
7. The device of claim 6 , wherein the compression of the reagent compartment releases the disinfectant or antimicrobial agent from the reagent compartment to disinfect the female luer connector or the male luer connector.
8. The device of claim 1 , wherein the disinfectant or antimicrobial agent is selected from the group consisting of isopropyl alcohol, ethanol, 2-propanol, butanol, methylparaben, ethylparaben, propylparaben, propyl gallate, butylated hydroxyanisole (BHA), butylated hydroxytoluene, t-butyl-hydroquinone, chloroxylenol, chlorohexidine, chlorhexidine diacetate, chlorohexidine gluconate, povidone iodine, alcohol, dichlorobenzyl alcohol, dehydroacetic acid, hexetidine, triclosan, hydrogen peroxide, colloidal silver, benzethonium chloride, benzalkonium chloride, octenidine, antibiotic, and mixtures thereof.
9. The device of claim 1 , wherein the disinfectant or antimicrobial agent is a fluid or a gel.
10. The device of claim 1 , wherein the female connector is selected from a group consisting of needle-free connectors, stopcocks, and hemodialysis connectors.
11. The device of claim 1 , wherein the male connector is an intravenous tubing end or stopcock.
12. The device of claim 1 , further comprising a peelable seal on the open distal end of the cap body.
13. The device of claim 12 , wherein the peelable seal comprises an aluminum or multi-layer polymer film peel back top.
14. The device of claim 1 , further comprising a permeable membrane disposed between the exterior wall surface and the interior wall surface of the reagent compartment.
15. The device of claim 1 , wherein the coupling cylinder side wall is made of a thin sheet of metal.
16. The device of claim 15 , wherein the thin sheet of metal is perforated.
17. The device of claim 15 , wherein the thin sheet of metal is meshed.
