Abstract

The utility model discloses a saliva collection device which can store a reagent. The saliva collection device is mainly formed by four parts which are an upper cover, a collection funnel, a collection tube and a collection tube plug lid. The center region of the upper cover is provided with a reagent storage zone, reagent is sealed in the reagent storage zone by plastic film, the upper end of the collection funnel is internally provided with a plurality of wedged salients, the collection funnel can be connected with the upper cover in a threaded way, an opening arranged at the upper end of the collection tube can be inserted between the inner wall and the outer wall at the lower end of the collection funnel, and the collection tube plug lid is used for plugging the collection tube to prevent leakage and pollution of saliva. When collected, the saliva flows into the collection tube by the collection funnel, the collection funnel and the upper cover are tightly screwed, and the wedged salients in the collection funnel cut the plastic film of the center reagent storage zone of the upper cover to be broken to cause the reagent to be packaged in the plastic film to flow out. The reagent flows into the collection tube by the collection funnel, and is mixed with the saliva in the collection tube. The collection funnel and the upper cover are removed, and the collection tube plug lid is used to plug the collection tube. The utility model has the characteristics of small structure and convenient use, and also has the function of reagent storage.

Description

A kind of saliva harvester that can store reagent

Technical field

The utility model relates to a kind of saliva harvester that can store reagent, and it is small and exquisite that it has structure, and advantage easy to use also has the functional characteristics that reagent stores.

Background technology

One of sample that often adopts when saliva is clinical examination and scientific research.Because contain carbonate in the saliva; phosphate and protein; and human body is when salivating; the epithelial cell that often has some disengagings can be blended in the saliva; by salivary component is carried out check and analysis; help some diseases is diagnosed; physiological function to body is assessed; and levels of drugs monitored; and by check and analysis to contained inhereditary material in the saliva; can also help the hereditary feature of body is carried out analysis and judgement; therefore saliva obtains pay attention to day by day and widespread use as a kind of sample easily of drawing materials in clinical examination and scientific research field.In addition, compare the collection of other samples, for example blood, urine, just, samples such as bile, marrow, saliva is gathered also has the advantage of pollution-free, no wound, no pain.

Though some saliva harvesters are also arranged in the market, but wherein some is as container with urine cup or sanitary cup, these container bores are bigger, be difficult to sealing, be not easy to transporting and preserving of sample, especially be not suitable for the collection of big specimen amount, some then clear-cut heparin tube of directly using is as container, but because the heparin tube relative aperture is less, be unfavorable for collecting saliva sample, cause pollution easily, also some draws saliva sample with cotton swab in experimenter's mouth, but the saliva sample amount that this acquisition method is gathered on the one hand is fewer, may influence the result of clinical detection or scientific research, and the sterilization problems of cotton swab may become one of potential safety hazard of sampling on the other hand.

In addition, sometimes also need to carry out at once the relevant detection pre-treatment after the saliva sample collection, for example cast-off cells in the saliva sample are carried out cracking, fixing etc. with immobile liquid, and existing saliva harvester all can't be finished the pre-treatment process that detects, needing increases follow-up link, has reduced work efficiency.

Summary of the invention

The purpose of this utility model provides a kind of saliva harvester that can store reagent, and it is small and exquisite to have structure, easy to use, also has the functional characteristics that reagent stores.

The employed technical scheme of shortcoming that the utility model solves other saliva harvesters is: the saliva harvester totally is made up of loam cake, collection funnel, collection tube, collection tube gag four parts.There is a reagent storage area loam cake central area, in reagent is sealed in plastic sheeting, gather inside, funnel upper end several wedge shape projectioies are arranged, gathering funnel can be connected with loam cake by engage thread, the shape of collection tube is identical with heparin tube, its upper end open can be inserted between the inside and outside wall of gathering the funnel lower end, and the collection tube gag is used for filling in the envelope collection tube, prevents saliva seepage, pollution.When gathering saliva, the sampling pipe upper end is inserted between the inside and outside wall of gathering the funnel lower end, experimenter's saliva that spues flows into collection tube by gathering funnel, will gather funnel with loam cake screws, and the interior wedge shape projection of collection funnel is cut the plastic sheeting of reagent storage area, loam cake center, the reagent of wherein encapsulation is flowed out, flow into collection tube by gathering funnel, mixes, remove sample funnel and loam cake with wherein saliva sample, with collection tube gag plug envelope collection tube, finish the saliva gatherer process.

Compare with existing product, the advantage that the utlity model has is:

1. structure is small and exquisite, and is easy to use.

2. have the functional characteristics that stores reagent, can need by clinical or scientific research, the storage related reagent when finishing the saliva sample collection, is finished the processing to sample.

3. gatherer process does not directly contact human body, does not cause injury of human.

4. the seepage of saliva sample can not take place in the gatherer process.

5. the saliva sample sealing is preserved, and prevents that sample from polluting, and do not pollute the environment simultaneously yet.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an embodiment outside drawing of the present utility model.

Fig. 2 is the utility model loam cake upward view.

Fig. 3 is that the utility model is gathered the funnel synoptic diagram.

Fig. 4 is that the utility model is gathered the funnel upward view.

1. loam cakes are 2. gathered funnel in the accompanying drawings, 3. collection tube, 4. collection tube gag, 5. reagent storage area, 6. wedge shape projection, 7. collection funnel lower end inwall, 8. collection funnel lower end outer wall.

Embodiment

Fig. 1 has represented an embodiment outside drawing of the present utility model in detail, and the utility model comprises loam cake (1), gathers funnel (2), collection tube (3), collection tube gag (4) four parts.

When gathering saliva sample, collection tube (3) upper end is inserted between the inwall (7) and outer wall (8) of gathering funnel (2) lower end, the experimenter spues saliva by gathering funnel (2) inflow collection tube (3), to gather funnel (2) screws with loam cake (1), gather the plastic sheeting that the interior wedge shape projection (6) of funnel (2) is cut reagent storage area, loam cake (1) center (5), the reagent of wherein encapsulation is flowed out, flow into collection tube (3) by gathering funnel (2), mix with saliva sample wherein, remove sampling funnel (2) and loam cake (1), with collection tube gag (4) plug envelope collection tube (3), finish the saliva gatherer process.
