Abstract

A device for the collection and testing of a fluid specimen is disclosed and claimed. The invention is particularly useful for collecting and testing human urine specimens but may also be employed in the veterinary environment or any time a potentially hazardous fluid is to be collected and tested and isolation of the specimen from testing personnel is desired. The invention keeps the specimen enclosed and sealed during transport and testing to facilitate safe handling of specimen. Some embodiments of the invention are highly resistent to tampering by the patient or during transport.

Claims

1. A fluid specimen collection and testing apparatus adapted for collecting and testing a single quantity of fluid specimen, the apparatus consisting essentially of:

(a) a container having within its interior a single fluid specimen retention chamber;

(b) means for absorbing a single fluid specimen into an absorbent material, said absorbing means being adapted for placement within said specimen retention chamber,

(c) means for sealing a fluid specimen retained by said absorbent material within said specimen retention chamber of said container, and

(d) an accessory tip constructed and adapted to mount to said container, said accessory tip comprising a substantially fluid-tight transparent sleeve to form a single fluid specimen testing chamber, and a dry paper reagent strip disposed within said sleeve, said fluid specimen testing chamber being in fluid communication with said specimen retention chamber when said accessory tip is mounted to said container so that transmission of fluid specimen from said absorbent material to said reagent strip may be effected;

wherein a quantity of fluid specimen may be collected by contacting said absorbent material with fluid specimen to initiate performance of a test; and

wherein said fluid specimen collection and testing apparatus is adapted to be manipulated entirely in the user'"'"'s hands without the necessity of the use of any type of mount or stand.

2. A fluid specimen collection and testing apparatus as recited in claim 1 wherein said absorbent material is hydrophilic.

3. A fluid specimen collection and testing apparatus as recited in claim 2 wherein said reagent strip comprises a plurality of reagents to enable testing a single fluid specimen for a plurality of conditions.

5. A device as recited in claim 1 wherein said accessory tip is removably mountable to said barrel in fluid-tight engagement therewith.

6. A device as recited in claim 5 wherein said reagent strip comprises a plurality of reagents to simultaneously test a quantity of fluid specimen for a plurality of conditions.

7. A device as recited in claim 5 wherein a fluid specimen absorbed by said absorbing means may be sealed in fluid-tight confinement within the fluid collection and testing apparatus.

8. A device as recited in claim 7

wherein said plunger includes a sealing ring for preventing escape of fluid specimen from the proximal end of the barrel;

wherein said barrel and said barrel adapter further comprise threads for mounting said barrel adapter to said barrel;

wherein said barrel adapter includes a male luer lock for receiving said accessory tip; and

wherein said accessory tip includes female luer lock for mounting to said barrel adapter.

4. A fluid specimen collection and testing apparatus consisting essentially of:

(a) a barrel having a proximal barrel end and a distal barrel end, said proximal barrel end being unconstrained to permit insertion of a plunger therein, said distal barrel end being unconstrained to permit protrusion of a plunger through the diameter of said distal barrel end,

(b) said plunger having a proximal plunger end and a distal plunger end, said plunger being constructed and adapted so that said distal plunger end is slidable into said barrel through said proximal barrel end and is slidable from within the interior of said barrel to protrude at the exterior of said barrel at said distal barrel end, said plunger having a handle at its proximal plunger end and said plunger having means for absorbing and retaining a fluid specimen mounted at its distal plunger end, said absorbing means being retractable into the interior of said barrel through said distal barrel end by sliding said plunger,

(c) a barrel adapter constructed and adapted to form a removable fluid tight engagement to said distal barrel end, said barrel adapter having a fluid transmitting aperture adapted to transmit fluid from the interior of said barrel to the exterior of said barrel adapter, and

(d) an accessory tip constructed and adapted to mount to said barrel adapter at the side of said barrel adapter opposite the side that engages said barrel, said accessory tip comprising a substantially fluid-tight transparent sleeve that forms a single fluid specimen testing chamber, and a dry paper reagent strip disposed within said single fluid specimen testing chamber, said accessory tip having a fluid receiving aperture adapted to receive fluid transmitted from said fluid transmitting aperture into said testing chamber, said reagent strip being positioned within said testing chamber so that fluid communicated from said barrel through said fluid transmitting aperture and through said fluid receiving aperture may contact said reagent strip to initiate performance of a test;

wherein said barrel adapter may be removed from said barrel and said plunger may be extended to protrude from within the interior of said barrel to expose said absorbing means to a fluid specimen. causing a portion of a fluid specimen to be absorbed by and retained in said absorbing means;

wherein said barrel adapter may be remounted on said barrel, said accessory tip may be mounted on said barrel adapter, and said distal plunger end may be slid toward said barrel adapter resulting in a compression of said absorbing means between said distal plunger end and said barrel adapter, forcing a quantity of fluid specimen from said absorbing means, through said fluid transmitting aperture of said barrel adapter, through said fluid receiving aperture of said accessory tip, into said testing chamber and into contact with said reagent strip; and

wherein said fluid specimen collection and testing apparatus is adapted to be manipulated entirely in the user'"'"'s hands without the necessity of the use of any type of mount or stand.
