Male medical implement cleaning device
View Patent ↗A cleaning device for a medical implement having a male protrusion. The cleaning device including a housing defining an inner cavity by and having an inner wall that encloses the inner cavity and an opening. The inner wall has a recess near the opening to the housing. The recess has a diameter that is greater than a diameter of the opening. The cap further includes a movable piston having a forward end and rearward end surrounded by a flexible flange that extends outward to abut the inner wall near the recess of the housing. The rearward end of the movable piston configured to contact couple with a distal end of the male protrusion to move the piston toward a distal end of the housing opposite the opening of the housing to provide a portion of the cleaning solution to the male protrusion.
1. A cleaning device for a medical implement having a male protrusion, the cleaning device comprising:
a housing defining an inner cavity, the housing having an inner wall that encloses the inner cavity and an opening, the inner wall having a recess near the opening to the housing;
a cleaning solution in the inner cavity of the housing; and
a movable piston within the inner cavity having a rearward end facing the opening of the housing and a forward end opposite the rearward end, the rearward end surrounded by a flexible skirt that flares outward to abut the inner wall near the recess to maintain the cleaning solution in the inner cavity prior to receipt of the male protrusion into the inner cavity, the rearward end of the movable piston configured to contact a distal end of the male protrusion to move the piston toward a distal end of the housing opposite the opening of the housing to provide a portion of the cleaning solution to the male protrusion,
wherein the diameter of the inner wall is wider at the recess than at the distal end of the housing and at the opening, and
wherein the flexible skirt flares away from the piston in a direction that is opposite from the forward end and is sized to be slightly wider than the recess and the inner wall of the inner cavity of the housing.
2. The cleaning device in accordance with claim 1 , further comprising a removable seal coupled to the opening of the housing to seal the opening and maintain the piston and the cleaning solution within the inner cavity prior to receipt of the male protrusion.
3. The cleaning device in accordance with claim 1 , wherein the housing further includes one or more threads extending out from an outer surface of the housing proximate the opening.
4. The cleaning device in accordance with claim 1 , wherein the housing further includes one or more ridges extending out from an outer surface of the housing near the distal end of the housing opposite the opening.
5. The cleaning device in accordance with claim 1 , further comprising venting means between the opening and the recess.
6. The cleaning device in accordance with claim 1 , wherein the inner cavity is cylindrical.
7. The cleaning device in accordance with claim 6 , wherein the recess extends around the circumference of the inner cavity.
8. The cleaning device in accordance with claim 6 , wherein the recess occupies less than the full circumference of the inner cavity.
9. The cleaning device in accordance with claim 1 , wherein the rearward end of the movable piston has a male protrusion interface comprising one or more features selected from the group consisting of grooves, channels and raised portions.
10. The cleaning device in accordance with claim 9 , wherein the raised portions of the male protrusion interface of the piston comprise raised ridges, wherein the male protrusion of the medical implement defines a lumen, and wherein the raised portions of the male protrusion interface contact the male protrusion while inhibiting sealing the lumen.
11. The cleaning device in accordance with claim 1 , wherein the housing is a cap.
