FLUID COLLECTION DEVICE WITH EXPRESSER PLUG HOLDER
A fluid collection device has a collection vial with a reservoir chamber for receiving a fluid sample. An elongated expresser is disposed within the collection via, which includes a fluid permeable base enabling passage of fluid sample into the reservoir chamber. A fluid test card is supported by an expresser bottom flange within the collection vial and a plunger is provided for compression of a swab saturated with fluid specimen into the reservoir chamber. A cap is provided for engaging the collection vial in order to seal the compressor, fluid test card, compressed swab, and plunger within the collection vial.
1 . A fluid collection device comprising:
a collection vial having an open end and a closed bottom with a reservoir chamber for receiving a fluid sample;
an elongated expresser disposed in said collection vial, having a fluid permeable base enabling passage of the fluid sample into said reservoir chamber, and a bottom flange disposed above said closed bottom;
a plunger, having a piston and a grip, sized for reception by said expresser;
a swab, fixable to the plunger piston, for absorbing the fluid sample and expressing the fluid sample through the expresser base upon compression by said piston; and
a cap for engaging the collection vial open end in order to seal the expresser, fluid test card, swab and plunger within said collection vial.
2 . The fluid collection device of claim 1 , wherein said plunger has a length causing said swab to remain compressed during cap engagement with said collection vial, said swab being compressed against the expresser base and sealing the fluid sample within said reservoir chamber.
3 . The fluid collection device of claim 1 , further comprising a fluid test card supported by the bottom flange and having an end for absorbing a portion of the fluid sample from said reservoir chamber.
4 . The fluid collection device of claim 3 , wherein said bottom flange has a slot therethrough and the test card end includes a tongue sized for insertion through the bottom flange slot.
5 . The fluid collection device of claim 4 , wherein said elongated expresser has a substantially circular cross section.
6 . The fluid collection device of claim 5 , wherein said expresser further comprises a radially extending top flange having a flat portion, aligned with the bottom flange slot for supporting said test card.
7 . The fluid collection device of claim 1 , wherein the vial includes a tapered inside diameter, narrower toward the vial bottom, and the bottom flange has dimensions for engaging the vial inside diameter proximate the vial bottom.
8 . The fluid collection device of claim 1 , wherein the closed bottom of the vial includes a conical portion and the bottom flange engages the conical portion of the vial.
9 . The fluid collection device of claim 1 , wherein said fluid permeable base includes a plurality of spaced apart ribs.
10 . The fluid collection device of claim 1 , wherein said cap includes a bearing surface for engaging the plunger grip for forcing said plunger and piston within the vial upon cap engagement with the vial top in order to compress the swab against the expresser base.
