Description

Fecal sample quantitative collection device

Technical field

Medical experiment detection device technology field is the utility model is related to, particularly a kind of fecal sample quantitative collection dress Put.

Background technology

The detection of excrement has special meaning to diagnosing some diseases, but conventional use of sample-collecting box is very simple and crude, no Easy to the retention of excrement sample, detection also needs the direct operating of contacts of hand when sampling, so that person under inspection and tester's inconvenience are not only caused, and And smell because of excrement sample or the pathogen that contains and easily form pollution sources, reviewer need to endure sample stink, and excrement Sample cannot quantify, and be not suitable for quantitative testing.Conventional sampler there are it is following the defects of, it is impossible to meet the need of clinical practice Will：(1) handshake part of traditional sampler is short and thick, grip inconvenience, and easily makes both hands dirty；(2) legacy sampler is more Sampled using small spoon structure, it is necessary to the excrement quantity that collection can be only achieved sampling request be repeated several times, operating process is complicated, easily User is set to produce psychological pressure；(3) excrement of legacy sampler collection is not readily separated, and can not fully be reacted with lysate, unfavorable In the progress of scientific research personnel's follow-up work；(4) legacy sampler uses the assembling and fixation of single screw thread or buckle, no It can effectively prevent lysate and mix and leak out and pollute with excrement；(5) legacy sampler uses cheap transparent plastic system mostly Make, stress is broken, and easily brings psychological pressure to user when in use；(6) legacy sampler is not equipped with defecate collection box, It can not realize stool and urine separation and pollute excrement, serious inconvenience is brought to feces collection work；(7) tradition sampling is random, no It can guarantee that collection capacity, cause too much or very little.

Patent document 1 discloses a kind of stool collection cup, including cup body, the head cover arranged on cup body top and through top Lid stretches into the sample spoon in cup body, is equipped with a partition plate in the cup body, the both sides of the partition plate are contacted with cup body inner wall line, described The lower end of partition plate is equipped with strainer；The inner cavity of cup body is isolated stir chamber and test chamber by the strainer and partition plate, on the head cover Instrument connection is equipped with test chamber corresponding position.The patent has gathered sample and has been diluted, mixes, filters, and admixing medical solutions are only logical The strainer for crossing bottom enters test chamber, therefore admixing medical solutions are than more uniform, but the patent can not quantitative collection sample, liquid and sample Originally it can not automatically and accurately match and be not suitable for storage and transport, can not facilitate and wholesomely sample, security reliability is poor And easy secondary pollution.

Patent document 2 discloses that one kind adopts closet, include sample-storing bottle, bottom cover, protecgulum, blanking cover, an end cap of sample-storing bottle Equipped with U-shaped sealing shroud, adopting the just bottom of rod perforation U-shaped sealing shroud and extending in sample-storing bottle, bottom cover in bottom cover, with helicla flute Outer wall be connected with the end of sample-storing bottle, bottom carries the protecgulum of drain pipe, sets sealing ring, the outer wall of protecgulum in its bottom It is connected with the other end of sample-storing bottle, the outlet of drain pipe is through hole, and drain pipe is externally connected with blanking cover, blanking cover bottom and discharge opeing Pipe is provided with gasket between outlet.The setting of the helicla flute and U-shaped sealing shroud of the patent acquisition rod so that each inspected excrement It is small to measure amplitude of variation, but the patent can only fix the collection of scheduled volume, can not accomplish the quantitative collection of a variety of scheduled volumes, it is even more impossible to So that liquid and sample automatically and accurately match and are not suitable for storage and transport.

Patent document 3 discloses that a kind of excrement quantitative collection bottle, including bottle cap set (1), serum cap (2), transparent plastic bottle Body (3) and bottle holder (4), are equipped with four symmetrical pipes (5) on serum cap (2), and pipe (5) hypomere wall is equipped with groove (6), pillar (7) is equipped with pipe (5), pillar (7) hypomere is equipped with bulge loop (8), and pillar (7) upper end is equipped with pressing plate (9), and four right Pipe (5) lower end outside edge of title is equipped with a circular card slot (10), and discoid protrusion is equipped with circular card slot (10) (11), discoid raised (11) are equipped with the diminishing casing of caliber size (12), and serum cap (2) center is equipped with connection cavity (13), connect cavity (13) hypomere and be equipped with threaded connection (14), be threadedly coupled (14) and be equipped with hollow circular tube (15), hollow circular tube (15) hypomere is equipped with cylindrical acquisition cavity (16), is equipped with piston sheet (17) in cylindrical acquisition cavity (16), piston sheet is set on (17) There are piston rod (18), piston rod (18) drawing-in hollow circular tube (15), piston rod (18) epimere is equipped with card slot (19), connects cavity (13) edge is equipped with elastic force registration arm (20), and transparent plastic body (3) is equipped with scale (21), and serum cap (2) edge is equipped with note The mouth of a river (22), water filling port (22) are equipped with elastic sealing film (23), and transparent plastic body (3) hypomere is equipped with funnel (24), funnel (24) root is equipped with strainer (25), and funnel (24) hypomere is equipped with water outlet (26).The patent is when carrying out just sample inspection to environment Pollute small, easy to operate health, and can quantitative collection excrement, but the patent can not liquid and sample automatically and accurately match And it is not suitable for storage and transport, sampling operation is complicated, poor reliability.
