Description
Technical field
The utility model relates to a kind of biological detection utensil, is a kind of biological sampling testing device concretely.
Background technology
At present, biological specimen comprises that the collection of plant and transmission are very important links, and in the collection and transmittance process of biological specimen, the method for often using is to sample by sampling swab, and is convenient and swift, can alleviate sampling lab technician's burden.Existing sampling swab generally comprises thief rod and swab head, and thief rod is a barred body, and by the sampling of swab head, the swab head after then sampling is put into test liquid, thereby tests or chemically examine by testing apparatus.Existing sampling thief generally leaks outside, and is easily contaminated in operating process, so easy impact check and chemical examination effect.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, provides a kind of simple in structure, and convenient the collection can prevent sample contamination, thereby guarantees the biological sampling testing device of check and result of laboratory test accuracy.
In order to reach above purpose, the technical scheme that the utility model adopts is: this biological sampling testing device, comprise thief rod, the upper end of described thief rod is provided with handle, the lower end of described thief rod is provided with the sampling head for sampling, it is characterized in that: the upper end of described handle is provided with the sampling knife for cutting sample, described handle lower end is connected be used to the reaction tube that holds thief rod, the lower end of described reaction tube is provided with the flexible pipe of splendid attire reactant liquor, is provided with one deck barrier film between described flexible pipe and reaction tube.
The utility model is also implemented by following measure: be provided be used to the lid that hides described sampling knife above described handle.
The beneficial effects of the utility model are: simple in structure, the convenient collection can prevent sample contamination, thereby guarantee the accuracy of check and result of laboratory test.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, thief rod; 2, handle; 3, sampling head; 4, sampling knife; 5, reaction tube; 6, flexible pipe; 7, barrier film; 8, lid.
Embodiment
As shown in Figure 1, the biological sampling testing device, comprise thief rod 1, the upper end of described thief rod 1 is provided with handle 2, the lower end of described thief rod 1 is provided with the sampling head 3 for sampling, and it is characterized in that: the upper end of described handle 2 is provided with the sampling knife 4 for cutting sample, and described handle 2 lower ends are connected be used to the reaction tube 5 that holds thief rod 1, the lower end of described reaction tube 5 is provided with the flexible pipe 6 of splendid attire reactant liquor, is provided with one deck barrier film 7 between described flexible pipe 6 and reaction tube 5.
Described handle 2 tops are provided be used to the lid 8 that hides described sampling knife 4.Not only prevent contaminatedly by lid 8, and prevent injured.
Described sampling head 3 contacts with barrier film 7.Hand is pinched flexible pipe 6 reactant liquors in flexible pipe 6 are torn barrier film 7 under pressure like this, and flows on sampling head 3, is convenient to sterile working.
During use, can be as required by the article cutting of sampling knife 4 with required sampling, or by sampling head 3 Direct Sampling, sample thief after the biological cell that collects like this or cutting is put into reaction tube 5, then hand is pinched flexible pipe 6 reactant liquors in flexible pipe 6 is broken through barrier film 7 under pressure, and flow on sampling head 3, make the interior reaction solution of flexible pipe 6 and the biological cell on sampling head 3 or biomolecule carry out chemical reaction, can prevent like this pollution that causes in sampling and transmittance process, guarantee the accuracy of check and result of laboratory test.
The utility model is simple in structure, and convenient the collection can prevent sample contamination, thereby guarantee the accuracy of check and result of laboratory test.
