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 comprising:

(a) a sealable fluid-tight enclosure adapted to receive and seal within its interior a hollow straw with an absorbent material affixed thereto, and

(b) said hollow straw having a longitudinal axis, a proximal end at one end of said longitudinal axis and a distal end at the opposite end of said longitudinal axis, said proximal and distal ends being closed to prevent entry of specimen, said straw comprising;

(i) a rigid sub-frame mounted to said proximal end of said hollow straw,

(ii) said absorbent material capable of collecting the fluid specimen, said absorbent material being mounted to said sub-frame, and

(iii) a reagent strip located within the interior of said hollow straw between said proximal end and said distal end, said reagent strip being in fluid isolation from said absorbent material;

wherein said proximal end is adapted to be grasped permitting deviation of said sub-frame from said longitudinal axis causing a fluid-permeable opening in said hollow straw, permitting fluid communication from said absorbent material to said reagent strip.

2. A device as recited in claim 1 wherein said fluid-tight enclosure is non-reopenable and non-resealable once sealed.

3. A device as recited in claim 1 wherein said reagent strip includes multiple patches of different reagents to test a fluid specimen with multiple reagents simultaneously.

4. A device as recited in claim 1 wherein said enclosure is constructed of transparent, flexible film.

5. A device as recited in claim 4 wherein said enclosure includes a temperature indicator.

6. A device as recited in claim 1 further comprising means of transporting, testing, and disposing of fluid specimen without exposing specimen to air, environment and personnel.

7. A fluid specimen collection and testing apparatus comprising:

(a) a sealable fluid-tight enclosure adapted to receive and seal within its interior a hollow straw with an absorbent material affixed thereto,

(b) said hollow straw having a proximal end and a distal end, said proximal and distal ends being closed to prevent entry of specimen, said straw having a rigid sub-frame mounted to said proximal end, said absorbent material capable of collecting the fluid specimen mounted to said sub-frame, scoring located on said hollow straw adjacent said proximal end to create a fluid permeable opening in said hollow straw, a reagent strip within said hollow straw between said scoring and said proximal end being in fluid isolation from said absorbent material;

wherein said proximal end is adapted to be grasped permitting deviation of said sub-frame from the longitudinal axis of said hollow straw causes said fluid-permeable opening in said hollow straw at said scoring, permitting fluid communication between said reagent strip and said absorbent material.

8. A device as recited in claim 7 wherein said fluid-tight enclosure is non-reopenable and non-resealable once sealed.

9. A device as recited in claim 7 wherein said reagent strip includes multiple patches of different reagents to test a fluid specimen with multiple reagents simultaneously.

10. A device as recited in claim 7 wherein said enclosure is constructed of transparent, flexible film.

11. A device as recited in claim 10 wherein said enclosure includes a temperature indicator.

12. A device as recited in claim 7 further comprising means of transporting, testing, and disposing of fluid specimen without exposing specimen to air, environment and personnel.
