Description

Cardia esophagus biological specimen sampler

Technical field

This utility model relates to a kind of cell collection device, particularly, relates to a kind of cardia esophagus biological specimen sampler.

Background technology

In known cell collection device, many employings net cryptomere, after entering esophagus, carry out inflation makes it heave, the abrasive material of edge is utilized to carry out cell collection, but when it extracts out from esophagus, heave due to net capsule and rub with larynx, cause the larynx of experimenter to reflect, produce strong discomfort.On the other hand, in cell harvesting process, cannot be separated by it, be not easy to various detection in later stage.

Summary of the invention

The purpose of this utility model is that providing a kind of improves experimenter's level of comfort, is convenient to the cardia esophagus biological specimen sampler of late detection.

For achieving the above object, this utility model adopts following technical scheme: cardia esophagus biological specimen sampler, cover esophagus at sampler 1 outer surface and draw in the net 3, esophagus draw in the net 3 one end stretch in sampler 1, sampler 1 top is connected with rope 2, esophagus draws in the net 3 original states for " V " shape, esophagus draw in the net 3 finish using after draw in sagging.

Further, described sampler 1 and esophagus draw in the net 3 to be included in soluble capsule 4, and esophagus draws in the net 3 constraints being subject to soluble capsule 4 and presses together in " V " shape.

Further, described esophagus draw in the net 3 material be fur.

Further, described esophagus draw in the net 3 the top of portion bristle with spoon shape body 31.

Further, described esophagus draw in the net 3 portion bristle be hollow form, portion bristle one side has mouth 32.

Further, described esophagus draws in the net that 3 all bristles have the microflute 33 increasing roughness.

Further, the first described sampler 11, second sampler 12, the 3rd sampler 13 are by being connected with externally threaded groove rotatable engagement with externally threaded projection 14.

Further, described sampler 1 is divided into the first sampler 11, second sampler 12, the 3rd sampler 13, and described sampler is connected by the connection strap 14 being easy to cut off or tear, and the material of described connection strap 14 is soft; First sampler 11, second sampler 12, the 3rd sampler 13 respectively corresponding first sample drop bottle 51, second sample drop bottle 52, the 3rd sample drop bottle 53, place DNA conserving liquid or RNA conserving liquid or exfoliated cell preservative fluid respectively in sample drop bottle.

Further, the Bottle cap top of described sample drop bottle has drip 55, and drip 55 seals by breaking disconnected bar body 54, and closure inside has filter course 57, bottle cap has the texture 56 increasing friction.

Further, every 5 centimetres of described rope 2 arranges a scale 21, and wherein the distance that increases progressively of every 5 centimetres, 10 centimetres, 20 centimetres arranges colour code.

The beneficial effects of the utility model:

1. in use, esophagus draws in the net from the most initial V shape to the sagging shape of gathering when taking out, occur to contact to greatest extent with esophagus during beginning, along with pulling in use procedure, esophagus draws in the net gradually to draw in and reduces the contact with esophagus, draw in completely when finally taking out from oral cavity, increase the comfort of experimenter, especially reduce larynx and reflect the discomfort brought;

2. the esophagus structure of portion bristle of drawing in the net is all collecting cell to greatest extent and designing, and improves collection capacity during each use further;

3. sampler is separable, and the cell that the bristle of its correspondence is collected drops into different sample drop bottle respectively and preserves, and is convenient to the later stage to carry out different types of test analysis.

detailed description of the invention:

Below in conjunction with accompanying drawing, this utility model is further illustrated:

With reference to Fig. 1 ~ 6, sampler 1 outer surface of the present utility model covers esophagus and draws in the net 3, esophagus draw in the net 3 one end stretch in sampler 1, sampler 1 top is connected with rope 2, esophagus draws in the net 3 original states for " V " shape, esophagus draw in the net 3 finish using after fall " V " shape in what draw in, described sampler 1 and esophagus draw in the net 3 to be included in soluble capsule 4, and esophagus draws in the net 3 constraints being subject to soluble capsule 4 and presses together in " V " shape.

As shown in Figure 2, after soluble capsule 4 is swallowed by experimenter, the other end of rope stays outside, after soluble capsule 4 arrives esophagus, soluble capsule 4 is dissolved, as shown in Figure 3, the esophagus be compressed in capsule 4 draws in the net 3 be expanded to original size and come in contact with esophagus cortex, esophagus now draws in the net 3 to present " V " shape, when sampler be subject to outside pull time, esophagus draw in the net 3 constantly and esophagus generation rubbing collection with the liquid of cell, as shown in Figure 4, esophagus draws in the net 3 to be constantly subject to drawing in gradually after frictional force and sagging, now substantially do not rub with esophagus, also can not produce larynx when pulling out from oral cavity and stimulate, the comfort of further raising experimenter.

With reference to Fig. 5 ~ 6, as preferred technical scheme, described esophagus draw in the net 3 preferred materials be fur.In order to strengthen the efficiency of bristle collecting cell, described esophagus draw in the net 3 portion bristle top with spoon shape body 31, and portion bristle is hollow form, further, esophagus draws in the net a side of 3 portion bristle and has mouth 32, all bristles has the microflute 33 increasing roughness.Spoon shape body 31 increase further esophagus draw in the net 3 with the contact area of esophagus, improve the service efficiency of sampler.

Conveniently operate, every 5 centimetres of described rope 2 arranges a scale 21(accompanying drawing and does not draw), wherein the distance that increases progressively of every 5 centimetres, 10 centimetres, 20 centimetres arranges colour code, such as from fag end down 5 centimeters identify a red circle, 10 centimeters identify a yellow circle, 20 centimeters identify a blue circle, by that analogy.According to scale, operator can know capsule arrives which position in human body.

Referring to figs. 1 through Fig. 8, described sampler 1 is divided into the first sampler 11, second sampler 12,3rd sampler 13, described sampler is connected by the connection strap 14 being easy to cut off or tear, described sampler is corresponding first drop bottle 51, second sample drop bottle 52, the 3rd sample drop bottle 53 respectively, places DNA conserving liquid or RNA conserving liquid or exfoliated cell preservative fluid in sample drop bottle respectively.The Bottle cap top of described sample drop bottle has drip 55, and drip 55 seals by breaking disconnected bar body 54, and closure inside has filter course 57.

During use, cut off the connection strap 14 of sampler, being cut off by sampler is after three sections, and drop in sample drop bottle respectively, cover lid, fully shakes up.When needing to detect, bar body 54 is broken disconnected, ooze the liquid of band cell from drip 55, food debris etc. filtered out by filtering layer 57 before liquid oozes.As preferably, bottle cap has the texture 56 increasing friction.These cells separately preserved can be used for the detection of DNA, RNA, protein, exfoliative cyte etc., and primary sample can realize multiple detection, fast very convenient.

Further, because connection strap 14 is soft, therefore sampler 1 bending can be discharged in soluble capsule 4, be conducive to capsule 4 to fill full, in other words, namely can place larger sampler in less capsule.

Certainly, these are only this utility model better embodiment, not limit the scope of application of the present utility model with this, other equivalent structure substituted any is all within its protection domain.
