Abstract

Provided is a disinfecting cap for a fluid path element having an inner lumen and an outer cylindrical wall surrounding the inner lumen. The disinfecting cap includes a housing configured to receive the inner lumen and the outer cylindrical wall of the fluid path element. The housing has an open proximal end, a closed distal end, and a sidewall extending between the open proximal end and the closed distal end to define an interior volume. A sleeve protrudes proximally from an inner surface of the closed distal end and defines an opening configured to receive the inner lumen of the fluid path element. A compressible absorbent material at least partially saturated with a disinfecting fluid is disposed within the interior volume of the housing and surrounding at least a portion of the sleeve.

First claim

1 .- 28 . (canceled)

29 . A disinfecting cap for a fluid path element having an inner lumen and an outer cylindrical wall surrounding the inner lumen, the disinfecting cap comprising:
a housing configured to receive the inner lumen and the outer cylindrical wall of the fluid path element, the housing comprising an open proximal end, a closed distal end, and a sidewall extending between the open proximal end and the closed distal end to define an interior volume; a sleeve protruding proximally from an inner surface of the closed distal end, the sleeve defining an opening configured to receive the inner lumen of the fluid path element; and a compressible absorbent material at least partially saturated with a disinfecting fluid, the compressible absorbent material disposed within the interior volume of the housing and surrounding at least a portion of an outer portion of the sleeve, wherein the outer cylindrical wall of the fluid path element is configured to be received in a disinfecting space between an inner surface of the housing and the sleeve such that movement of the fluid path element toward the closed distal end compresses the compressible absorbent material and releases at least a portion of the disinfecting fluid into the disinfecting space.

30 . The disinfecting cap of claim 29 , wherein an inner surface of the sleeve is configured to be in sealing engagement with the inner lumen of the fluid path element.

31 . The disinfecting cap of claim 29 , wherein the compressible absorbent material extends substantially from the closed distal end to the proximal end of the housing.

32 . The disinfecting cap of claim 29 , wherein the sleeve comprises one or more longitudinal ribs protruding radially outward and configured to engage the compressible absorbent material surrounding the outer portion of the sleeve to prevent rotation of the compressible absorbent material relative to the sleeve.

33 . The disinfecting cap of claim 29 , wherein the compressible absorbent material has an axial slot configured to receive the outer cylindrical wall of the fluid path element.

34 . The disinfecting cap of claim 29 , wherein the sleeve comprises a tab configured to provide a tactile or audio feedback when the inner lumen of the fluid path element is fully inserted into the sleeve.

35 . The disinfecting cap of claim 29 , wherein an inner surface of the sidewall comprises one or more radially inwardly protruding projections configured to removably engage the outer cylindrical wall and retain the disinfecting cap on the fluid path element.

36 . The disinfecting cap of claim 29 , wherein the absorbent material is a sponge.

37 . The disinfecting cap of claim 29 , wherein the absorbent material is cotton.

38 . The disinfecting cap of claim 29 , wherein the disinfecting fluid comprises isopropyl alcohol, ethanol, a combination thereof, or an aqueous solution thereof.

39 . The disinfecting cap of claim 29 , further comprising a gripping flange protruding distally from the closed distal end.

40 . The disinfecting cap of claim 29 , further comprising a seal removably connected to the open proximal end, wherein the seal fluidly seals the open proximal end.

41 . The disinfecting cap of claim 40 , wherein the seal comprises a pull tab protruding radially outward relative to the sidewall of the housing, and wherein the pull tab is configured to remove the seal from the open proximal end.

42 . A fluid path assembly comprising:
a fluid path element having an inner lumen and an outer cylindrical wall surrounding the inner lumen; and a disinfecting cap configured to connect to the fluid path element, the disinfecting cap comprising: a housing configured to receive the inner lumen and the outer cylindrical wall of the fluid path element, the housing comprising an open proximal end, a closed distal end, and a sidewall extending between the open proximal end and the closed distal end to define an interior volume; a sleeve protruding proximally from an inner surface of the closed distal end, the sleeve defining an opening configured to receive the inner lumen of the fluid path element; and a compressible absorbent material at least partially saturated with a disinfecting fluid, the compressible absorbent material disposed within the interior volume of the housing and surrounding at least a portion of an outer portion of the sleeve, wherein the outer cylindrical wall of the fluid path element is configured to be received in a disinfecting space between an inner surface of the housing and the sleeve such that movement of the fluid path element toward the closed distal end compresses the compressible absorbent material and releases at least a portion of the disinfecting fluid into the disinfecting space.

43 .- 54 . (canceled)

55 . The fluid path assembly of claim 42 , wherein the fluid path element is a Luer connector.

56 . The fluid path assembly of claim 42 , wherein the fluid path element is a multi-patient fluid path element.

57 . The fluid path assembly of claim 42 , wherein the fluid path element is a single-patient fluid path element.

58 . The fluid path assembly of claim 42 , wherein the fluid path element comprises:
a first connector element comprising a body, a first lumen, a first flexible leg, and a second flexible leg; and a second connector element comprising a body defining an undercut, a second lumen, a channel defined in the body, and at least one sealing element positioned within the channel, wherein the first flexible leg comprises a first flange and the second flexible leg comprises a second flange, wherein, upon engagement of the first connector element with the second connector element, the first flange and the second flange engage with the undercut of the body of the second connector element to prevent disengagement of the first connector element and the second connector element, and wherein the sealing element is configured to define a fluid tight seal between the second lumen of the second connector element and the first lumen of the first connector element to form a fluid path when the first connector element and the second connector element are engaged with one another.
