Description
Technical field
The utility model belongs to DNA detection equipment technical field, is specifically related to a kind of DNA detection sampler.
Background technology
Gene is a function fragment on DNA molecular, is the fundamental unit of genetic information, is the factor determining that all living things species are the most basic; The birth and old age, sickness and death of gene decider, be healthy, beautiful, long-lived because of, be operator and the regulation and control person of life.Therefore, where where is it life, just have gene, and the existence of all life and the form of decline are all by gene-determined, comprise your appearance, height, body weight, the colour of skin, personality etc. all inseparable with gene.
Gene test is the technology detected DNA by blood, other body fluid or cell, get the Oral Mucosal Cells or other histocytes that detected person comes off, after its gene information that increases, by particular device, the DNA molecular information in detected person's cell is detected, the risk that precognition health suffers from the disease, analyze the various genetic profile contained by it, thus make people can understand the gene information of oneself, thus by improving oneself living environment and living habit, avoid or delay the generation of disease.
Current, the DNA detection sampler of China achieves huge progress, but compared with international advanced country, also have larger gap, an a lot of technical difficult problem is urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is just to provide a kind of DNA detection sampler to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of DNA detection sampler, comprise syringe needle, umformer, piston and handle, piston barrel inner bottom part is provided with packing ring, described piston is provided with above described packing ring, described piston is connected to pull bar, described piston barrel top is provided with piston cover, described pull bar reaches outside cylinder through described piston cover, described pull bar top is provided with described handle, be provided with described umformer below described piston barrel, described piston barrel side is provided with joint, and described umformer side is provided with valve, described valve is provided with valve handle, below described umformer, is provided with syringe needle.
In said structure, described syringe needle is inserted sample body, by piston described in described handle and described pull bar post-tensioning, sample enters in described piston barrel, then imports detecting instrument by described joint, in the process, described syringe needle is used for from sample body sampling, and described pull bar is used for pulling described piston, thus sample drawn, described joint is for connecting peripheral equipment, and realizing sample derives.
In order to improve its working efficiency further, itself and described piston removably connect by the buckle on described pull bar, and the described pull bar the other end is connected with described handle threads.
In order to improve its working efficiency further, described packing ring and described piston barrel glued joint, and it is inner that described umformer is positioned at described piston barrel.
In order to improve its working efficiency further, it is inner that described valve is positioned at described piston barrel, and described valve handle is connected with described valve.
In order to improve its working efficiency further, described syringe needle is buckled on described piston barrel.
The beneficial effects of the utility model are: the utility model structure is simple, easy to operate, and sampling accurately, is beneficial to cleaning, decreasing pollution, has boundless application prospect.
Accompanying drawing explanation
Fig. 1 is the structure iron of a kind of DNA detection sampler described in the utility model.
1, syringe needle; 2, valve; 3, joint; 4, packing ring; 5, piston; 6, pull bar; 7, piston barrel; 8, piston cover; 9, handle; 10, valve handle; 11, umformer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of DNA detection sampler, comprise syringe needle 1, umformer 11, piston 5 and handle 9, piston barrel 7 inner bottom part is provided with packing ring 4, piston 5 is provided with above packing ring 4, piston 5 is connected to pull bar 6, piston barrel 7 top is provided with piston cover 8, pull bar 6 reaches outside cylinder through piston cover 8, and pull bar 6 top is provided with handle 9, is provided with umformer 11 below piston barrel 7, piston barrel 7 side is provided with joint 3, umformer 11 side is provided with valve 2, valve 2 is provided with valve 10, is provided with syringe needle 1 below umformer 11.
In said structure, syringe needle 1 is inserted sample body, by handle 9 and pull bar 6 post-tensioning piston 5, sample enters in piston barrel 7, then imports detecting instrument by joint 3, in the process, syringe needle 1 is for from sample body sampling, and pull bar 6 is for pulling piston 5, thus sample drawn, joint 3 is for connecting peripheral equipment, and realizing sample derives.
In order to improve its working efficiency further, itself and piston 5 removably connect by the buckle on pull bar 6, pull bar 6 the other end is threaded with handle 9, packing ring 4 and piston barrel 7 glued joint, it is inner that umformer 11 is positioned at piston barrel 7, it is inner that valve 2 is positioned at piston barrel 7, and valve is connected with valve 2 10, and syringe needle 1 is buckled on piston barrel 7.
More than show and describe ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and effect thing thereof.
