Abstract

The utility model discloses a sample storage tube which comprises a tube body and a tube cap. A sealing protrusion capable of being inserted in and sealing a tube orifice of the tube body is arranged on a top inner wall of the tube cap, the undersurface of the sealing protrusion is provided with a conical hole, and a clamping groove is arranged at a position with small diameter on an upper portion of the conical hole. The conical hole and the clamping groove are arranged on the sealing protrusion of the tube cap, when the tube cap is tightly closed, a root edge of the sealing protrusion seals the tube orifice of the tube body, and a handle of a sampling swab is inserted in the clamping groove along the conical hole to enable the sampling swab and the tube cap to be fixed together. Operators only contact the tube cap to take out the sampling swab during sample taking, so that mutual contamination is avoided. The sample storage tube has the advantages of convenience for using and operating, reduction in sample contamination, low manufacturing cost and the like.

Description

The Sample storage pipe

Technical field

The utility model relates to a kind of Sample storage pipe.

Background technology

In clinical medicine and scientific research experiment field, the normal operation sampling swab extracts sample and puts into the Sample storage pipe and carry out preservation, transportation, sampling swab is made of handle, connecting link and sampling head three parts, general decreased food is longer, hold with convenient taking, can adjust front and back when holding, be fit to different crowd.And the length of general Sample storage pipe is shorter, therefore, the general structure that is easy to fracture that adopts of sampling swab handle of the prior art, sampling swab is just put into the Sample storage pipe after extracting sample like this, and the handle that fractures, and covers the pipe cap sealing preservation.When taking sample later on, opening pipe cap arrests handle take out sampling swab and sample from the Sample storage pipe again, because the Sample storage pipe generally has nutrient solution or similar liquids, the handle portion of unavoidable meeting contamination sampling swab in transportation or preserving process, so, the operator might be infected with sample liquids in taking the sample process, and sample also might be contaminated in taking the sample process.

Summary of the invention

In order to solve above-mentioned technical matters, the purpose of this utility model provides a kind of easy to use, Sample storage pipe of reducing sample contamination, low cost of manufacture.

To achieve the above object, the utility model has adopted following technical scheme:

A kind of Sample storage pipe comprises body and pipe cap, and the top inner wall of described pipe cap is provided with can be inserted in the tube mouth and the seal convexity of sealing, and the bottom surface of seal convexity is provided with bellmouth, and the minor diameter place, top of bellmouth is provided with draw-in groove.

As preferably, thereby be provided with the cross sectional shape of a plurality of card article draw-in grooves in the described draw-in groove and the handle cross sectional shape of sampling swab is complementary.

Described body and pipe cap are threaded.In the described body sampling swab is housed, the handle of sampling swab and the draw-in groove of described pipe cap are tightly fixed.

The utility model is owing to having adopted above technical scheme, seal convexity in block arranges bellmouth and draw-in groove, like this when block covers tightly, the root edges sealed tube body mouth of pipe of seal convexity, the handle of sampling swab inserts in the draw-in groove, so that sampling swab and pipe cap are fixed as one along bellmouth.The operator only contacts pipe cap and can take out sampling swab, thereby avoided mutual pollution in taking the sample process, has the advantages such as use is easy to operate, minimizing sample contamination, low cost of manufacture.

Fig. 2 is the cut-open view of the utility model pipe cap;

Fig. 3 is the upward view of Fig. 2.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.

Embodiment 1:

Such as Fig. 1, Fig. 2, a kind of Sample storage pipe shown in Figure 3, comprise body 1 and pipe cap 3, the top inner wall of described pipe cap 3 is provided with can be inserted in body 1 mouth of pipe and the seal convexity 31 of sealing, and the bottom surface of seal convexity 31 is provided with bellmouth 33, and the minor diameter place, top of bellmouth 33 is provided with draw-in groove 32.Thereby being provided with the cross sectional shape of four card article 34 draw-in grooves 32 and the handle cross sectional shape of sampling swab 2 in the described draw-in groove 32 is complementary.Described body 1 and pipe cap 3 are threaded.

After the operator is with the sampling swab sampling, put into body 1, and the handle that fractures, because the handle of sampling swab 2 slightly grows tube mouth, so, cover pipe cap 3, in the pipe cap 3 screw-in processes, the handle of sampling swab 2 inserts in the draw-in grooves 32 and is tightly fixed along the bellmouth 33 of pipe cap 3, and sampling swab 2 and pipe cap 3 are fixed as one like this, open pipe cap 3 and can take out simultaneously sampling swab 2.

It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
