The present invention has the advantages of simple structure, convenient use, low price, visual, prompt and convenient experimental result, continuous multiple-step experiment, etc. The present invention can continuously complete steps of collection, processing, reaction, result obtaining, etc., of the samples and can be widely used for the fields of biochemical enzyme activity analysis, (such as blood sample analysis), microbial cultivation, urine specimen immunochemistry detection, pathogenic bacterium detection of clinical samples, etc.
Description
Technical field:
The present invention relates to a kind of chemical devices, particularly a kind of device of chemical analysis chemical examination.
Technical background:
The chemical analysis assay device is an apparatus medically commonly used.Present way is to deliver to the laboratory again behind the clinical collection sample to remove to do further assay in medical domain.But the precise results that will guarantee the quality of sample and chemical examination in this process is unusual difficulty often.In addition, because temporal delay will cause sample test result's accuracy and reliability to reduce.And to directly obtain result of laboratory test at the scene, and perhaps after collecting sample, in time sample being carried out pre-service, and then be sent to the laboratory and carry out further assay, present apparatus also is difficult to reach.
Summary of the invention:
The objective of the invention is to: provide a kind of simple in structure, the chemical analysis assay device that can in time handle to sample, and can see experimental result intuitively, to address the above problem.
The present invention constitutes like this: it is by reservoir (1), reaction tube (2) can damaged valve (3), and tubule (4) is formed, can damaged valve (3) forms, locate between needle (5) that the front end insertion of tubule (4) can damaged valve (3) and the valve body (6) by needle (5) and valve body (6); Can damaged valve (3) pack in the reservoir (1); Reservoir (1) is enclosed within the front end of reaction tube (2).
Needle (5) that can damaged valve (3) is connected as a single entity with valve body (6), and can fracture from the junction with needle (5).
Reservoir (1) is made with flexible material.
The tail end of tubule (4) can connect swab, oese, spiral sampling awl.
The tail end of reaction tube (2) can be for the sealing shape, chew shape, opening shape or connect next reaction tube for a short time.
All component materials all adopt transparent material.
Transparent material can adopt rubber or/and plastics.
The present invention compared with prior art has simple in structurely, easy to use, cheap, can obtain experimental result intuitively, in time, easily, and can finish advantage such as the rapid experiment of multistep continuously.It can finish collection, the processing of sample, step such as react, obtain a result continuously.Can be widely used in biochemical enzymes activity analysis (as blood sample analysis), microbe culture, the immunochemistry of urine sample detects, fields such as the germ detection of clinical sample.Concrete experimental procedure is as follows:
1, be stored in reagent in the reaction chamber before use;
2, introducing reagent from another reaction chamber handles sample;
3, the sample of then sample being introduced after having handled in the reaction chamber that reaction reagent is housed or with the reaction reagent introducing reacts;
4, introduce and to stop reaction reagent reaction is stopped;
5, can generate at the eve " on the spot " that reacts for unsettled reagent.
Description of drawings:
Accompanying drawing 1 is a basic structure synoptic diagram of the present invention;
Wherein a is reservoir (1), and b is can damaged valve (3), and c is tubule (4), and d is reaction tube (2), and e is an assembly drawing;
Accompanying drawing 2 connects the structural representation of swab for sealing shape, tubule (4) tail end for the tail end of reaction tube of the present invention (2);

Accompanying drawing 5 is the structural representation that connects next reaction tube for the tail end of reaction tube of the present invention (2).
Embodiment:
Embodiments of the invention 1: microbe culture
As Fig. 2, reservoir (1) is made with soft transparent rubber, and reaction tube (2) can damaged valve (3), and tubule (4) is made of plastic, reaction tube (2) tail seal, and the tail end of tubule (4) is placed with the microbe culture swab.Take away reservoir (1) earlier, take out tubule (4), gather the microbe culture sample, the microbe culture reagent solution is put into reservoir (1), then reduction with tubule (4) tail end swab.When beginning to test, with hand can damaged valve (3) needle (5) from fractureing with valve body (6) junction, tubule (4) is communicated with reservoir (1), push reservoir (1) then, make the microbe culture reagent solution reach the microbe culture swab of its tail end, with the sample reaction of gathering along tubule (4).
Embodiment 2: the preparation of thinning agent
As Fig. 3, accurately to take a sample with the oese of tubule (4) tail end, the needle that fractures then (5) makes the reaction reagent of reservoir (1) flow to oese and mixes with sample, can obtain accurate thinning agent.And it can be splashed into container by chewing for a short time of reaction tube (2) tail end.
Embodiment 3: the processing of solids sample
As Fig. 4, spiral sampling awl with tubule (4) tail end is got solid sample (as ight soil), again by being located at the compressing hole (7) in the reaction tube, make the solid sample on the spiral sampling awl reach aequum, needle (5) then fractures, make the reaction reagent of reservoir (1) flow to spiral sampling awl and solid sample reaction, obtain the result that wants.
Embodiment 4: immunochromatography detects
As Fig. 5,, and insert different reagent therein respectively in the tail end of reaction tube (2) two layers of filter paper of packing into.Connect another reaction tube (8) in the rear end of reaction tube (2), immuno-chromatographic test paper strip (9) is housed therein.In reservoir (1), reaction reagent solution is housed.When beginning to test, needle (5) is fractureed, reaction reagent solution arrives two layers of filter paper along tubule (4), through with filter paper in reagent enter reaction tube (8) after reacting, react with immuno-chromatographic test paper strip (9) again.
