Abstract

The utility model relates to a sampling tube which is formed by assembling a tube body, an inner plug and a tube cap, wherein the tube body is in a hollow thin-wall structure. The inner bottom part of the tube body is a conical body with four reinforcement ribs, the upper part of the tube body is provided with an outer thread, the inner plug is in a hollow thin-wall structure and inlaid in the inner upper part of the tube body, the tube cap is in a hollow structure, the periphery of the tube cap is provided with a thin straight thread, one end of the tube cap is provided with an inner thread, and the inner part of the tube cap is provided with a lug boss. The utility model has the following advantages: when the sampling tube is used, a sampling rod can not hurt the applied people and can avoid the cross infection of bacteria; the sampling amount of shedding cells of the oral cavity is guaranteed, and the detectable rate is increased; the large amount of complex hand operation of the detection stuff after the existing sampling operation is reduced, and the intermediate link time is saved. The utility model has the characteristics of convenient use, safety and reliability.

Description

Sampling tube

Technical field

This utility model relates to the molecular genetics field that is applied to, and refers to the sampling tube that a kind of disposable use sampling rod of gathering the oral cavity exfoliative cyte is used especially.

Background technology

Present two centrifuge tubes of 5ml of using, deposit normal saline for one, another is deposited cell fixation liquid, after sampling person uses disposable use oral cavity exfoliative cyte spatula to gather the oral cavity exfoliative cyte, immerse the normal saline centrifuge tube, repeatedly several times until the centrifugal liquid in pipe of normal saline by the limpid muddiness that becomes; All pour the centrifugal liquid in pipe of normal saline into cell fixation liquid centrifuge tube again, finish whole sampling work.Do like this and have certain defective: pour the centrifugal liquid in pipe of 5ml into another 5ml centrifuge tube, cause liquid leakage easily, can cause secondary pollution on the one hand, also can cause the collection capacity of oral cavity exfoliative cyte not enough, directly the effect of influence detection.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of sampling tube that is applied to disposable oral cavity exfoliative cyte sampling rod, cell fixation liquid is deposited in the inside, the first end of disposable oral cavity exfoliative cyte sampling rod sponge is extend in the sampling tube that contains cell fixation liquid, the design of sampling pipe shaft inner bottom part has the cylinder of four reinforcements, can fully push the sampling rod spongy top, cell fixation liquid is fully soaked in the spongy top, put interior plug, tighten pipe cap.Omit existing sampling back testing staff and will carry out a large amount of numerous and diverse manual operationss, saved interlude, and guaranteed the collection capacity of oral cavity exfoliative cyte, improved recall rate, reduced cross infection, had characteristics easy to use, safe and reliable.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: sampling tube is formed by pipe shaft, Nei Sai and pipe cap winding, wherein, pipe shaft is made disposable hollow and thin-walled structure by the PE material, and the pipe shaft inner bottom part is the cone that four reinforcements are arranged, and external screw thread is arranged at top; Interior plug adopts the PE material to make disposable hollow and thin-walled structure, and caulked is at the pipe shaft internal upper part; The hollow structure that pipe cap also adopts the PE material to make, pipe cap are with thin straight thread outward, and an end has female thread, screw with the external screw thread on pipe shaft top, and there is a boss inside, and the pipe shaft appearance has 1,2,3 and 4 milliliter groove.

Plug in described, top is the cylinder of caulked in pipe shaft, there are two horizontal reinforcements at middle part, cylinder periphery, the step of thin straight thread is arranged at the top, there is the hollow siphunculus inside, hollow siphunculus and cylinder inwall are affixed with reinforcement, the aperture of hollow siphunculus top endoporus and the external diameter of sampling rod coupling, and the endoporus below hollow siphunculus reinforcement junction has constant slope.

Superior effect of the present utility model is:

When 1, using, sampling tube itself can not injure being produced by user, and can stop the pathogenic bacteria cross infection;

2, guarantee the collection capacity of oral cavity exfoliative cyte, improved recall rate;

3, omit existing sampling back testing staff and will carry out a large amount of numerous and diverse manual operationss, saved the intermediate link time, had characteristics esy to use, safe and reliable.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is described further.

See also shown in Fig. 1～4, sampling tube of the present utility model is formed by pipe shaft 1, interior plug 2 and pipe cap 3 windings, wherein, pipe shaft 1 adopts the PE material to make disposable hollow and thin-walled structure, and pipe shaft 1 inner bottom part is the cone 12 that four reinforcements are arranged, and external screw thread is arranged at top; Interior plug 2 adopts the PE materials to make disposable hollow and thin-walled structure, and caulked is at pipe shaft 1 internal upper part; The hollow structure that pipe cap 3 also adopts the PE material to make, pipe cap 3 is outer to be with thin straight thread, and an end has female thread, screws with the external screw thread on pipe shaft 1 top, and there is a boss 31 inside, and pipe shaft 1 appearance has 1,2,3 and 4 milliliter groove;

Plug 2 in described, top is the cylinder 23 of caulked in pipe shaft 1, there are two horizontal reinforcements at cylinder 23 peripheral middle parts, the step 22 of thin straight thread is arranged at the top, there is hollow siphunculus 24 inside, hollow siphunculus 24 is affixed with reinforcement 25 with cylinder 23 inwalls, the aperture of hollow siphunculus 24 top endoporus 21 and the external diameter of sampling rod coupling, and the endoporus below hollow siphunculus reinforcement 25 junctions has constant slope.

When sampling tube of the present utility model uses, cell fixation liquid is deposited in the sampling tube the inside, use disposable oral cavity exfoliative cyte sampling rod, stretch into the oral cavity, with the spongy top saliva of suction port luminal sectetion as much as possible, fully soaked into (spongy top should not have foreign body adhesions such as food debris) when observing spongy top by saliva, the first end of sampling rod sponge is extend in the sampling tube that contains cell fixation liquid, because sampling pipe shaft inner bottom part is designed to the cone of four reinforcements, can push spongy top fully up and down, make cell fixation liquid fully soak in the spongy top, then spongy top is pushed in the sampling tube, put interior plug, tighten pipe cap and promptly finish whole sampling work.Can be immediately after sampling, preserve fast, omit existing sampling back testing staff and will carry out a large amount of numerous and diverse manual operationss, reduced cross infection, the more important thing is the collection capacity that has guaranteed the oral cavity exfoliative cyte, improve recall rate, saved the time of pilot process simultaneously greatly.
