Claims
- 1. A diagnostic specimen collector consisting of:
- an elongated hollow body open at one end and closed at the opposite end with a single orifice in said closed end;
- a plunger having sealing means on one end which is slidably inserted into, and in sealing relationship with, said body to vary the interior volume of said body;
- a closure for said closed end orifice consisting of a one-piece cap having an end wall with a skirt extension exteriorly mounted to encompass said closed end concentrically and rotatable thereabout and a nipple to receive compatible fittings of specimen taking medical devices extending outwardly from the outer surface of said end wall and an orifice in said closure passing axially through said nipple and said end wall, said closure being rotatable from a first position in which both orifices are out of communication and said closed end orifice is in a sealed condition to a second position in which both orifices are in sealed communication for the passage of a specimen upon movement of said plunger and back to said first position after passage of said specimen; and sealing means for the closed end orifice comprising an O-ring positioned concentrically with reference to said closed end orifice in an annular groove on an outer surface of said closed end, a portion of said O-ring extending above said closed end outer surface to create a friction-free space between said outer surface and a inner surface of said closure except for a moving area of sealing contact between said ring portion and the inner surface of the closure, said ring portion providing a bearing surface for said rotation of said closure and an agent for application to said specimen in the interior of said hollow body.
- 2. The collector according to claim 1 wherein said closure is positioned on said body by cooperating bead and annular recess means arranged on the exterior of the closed end and inner surface of said skirt extension.
- 3. The collector according to claim 1 wherein the axis of said orifice in said closed end is eccentric to the axis of said body and the orifice in said closure is eccentric to the central longitudinal axis of said closure.
- 4. The collector according to claim 1 wherein said sealing means comprises an annular bead formed integrally with said closed end around said closed end orifice.
- 5. The collector according to claim 1 wherein said agent is in a recess on an interior surface of said closed end.
- 6. The collector according to claim 1 wherein said agent is applied as a layer to an interior surface of said closed end.
- 7. The collector according to claim 1 wherein said plunger comprises a stem extending between said sealing means and a digital gripping member, a portion of said stem being deflectable relative to the axis of said stem to selectively engage said open end with one of a plurality of notched segments formed on an outer surface of said deflectable portion.
