The present invention provides an antiseptic cap for use with an access site having a housing with a wall defining a chamber, the wall having a set of threads on an inner surface of the wall; and an access site contacting surface associated with the housing having an antiseptic substance for contacting a surface of the access site. The present invention also provides an antiseptic cap equipped plunger assembly wherein an antiseptic cap is retained within a housing of the plunger.
1. An antiseptic cap assembly for use with an access site comprising:
a cap having a generally cylindrical side wall defining a chamber having an open upper end and an end wall closing the opposite end, the cap having a substantially flat outer bottom surface and an upper flange extending radially outward from the generally cylindrical side wall, the generally cylindrical side wall having a set of threads on an inner surface of the generally cylindrical side wall and a plurality of circumferentially spaced cap ribs on an external surface of the generally cylindrical side wall extending radially outward from and axially along the generally cylindrical side wall from the bottom surface to the upper flange of the cap;
an absorbent material within the cap having an antiseptic substance for contacting a distal surface of the access site;
a housing for receiving the cap, the housing having housing ribs on an inner surface of the housing corresponding to the cap ribs on the cap to prevent relative rotation between the housing and the cap; and
a seal on the housing to seal the cap in the housing.
2. The cap assembly of claim 1 wherein the absorbent material is positioned within the chamber against the end wall.
3. The cap assembly of claim 2 wherein the antiseptic substance is a liquid and the liquid is releasably retained within the absorbent material.
4. The cap of claim 1 wherein the absorbent material is attached to the housing by welding.
5. The cap of claim 1 wherein the antiseptic substance comprises a lower alcohol.
6. An antiseptic cap for use with an access site comprising:
a housing having a generally cylindrical side wall defining a chamber having an open upper end and an end wall closing the opposite end, the generally cylindrical side wall having a first diameter, the housing having a substantially flat outer bottom surface and an upper annular flange including an end on the generally cylindrical side wall and a wall extending away from the generally cylindrical side wall, the upper annular flange having a second diameter greater than the first diameter of the generally cylindrical side wall, the generally cylindrical side wall extending from the bottom surface to the open upper end, the generally cylindrical side wall having a set of threads on an inner surface of the generally cylindrical side wall, and a plurality of circumferentially spaced ribs on an external surface of the generally cylindrical side wall extending radially outward from and axially along an outermost peripheral surface of the generally cylindrical side wall at regular intervals about the entire cylindrical side wall from the bottom surface to the upper annular flange of the housing; and
an absorbent material within the housing having an antiseptic substance for contacting a distal surface of the access site.
7. The cap of claim 6 wherein the absorbent material is positioned within the chamber against the end wall.
8. The cap of claim 6 wherein the antiseptic substance is a liquid and the liquid is releasably retained within the absorbent material.
9. The cap of claim 6 wherein the absorbent material is attached to the housing by welding.
10. The cap of claim 6 wherein the antiseptic substance comprises a lower alcohol.
