Abstract

The utility model relates to a saliva picker with double tips, which comprises three parts of sample stick, tube shape main pipe and cover of sample exit; the sample entrance is arranged on the superior part of the main pipe, the sample stick is spirally connected with the sample entrance; the sample exit is arranged at the solum of the main pipe and the cover of sample exit is also spirally connected with the sample exit. The sample stick comprises three structures of up cover, plunger and imbitition cotton. The up cover is insert connected with the plunger that sticks to imbitition cotton through glue. A conical evection, which fits the evection groove of the sample exit and seals, is arranged at the bottom of the cover of sample exit. The up cover, main pipe and intracanalicular part are made of transparent plastic, the imbitition cotton is made of liquid adsorbing materials. The sample stick can be put into the hollow main pipe from the sample entrance, the liquid sample will drop out from the sample exit while opening the exit cover and pressing the outside wall of the main pipe facing the sponge. The utility model is simple and delicate in structure, easy in producing, transporting and operating; the device also has the advantage of being neat and tidy and convenient in operating.

Description

Double head saliva collector

Technical field

This utility model relates to a kind of double head saliva collector, the advantage that it has clean cleaning, is convenient to operate.

Background technology

Saliva is not only contained endogenous substance, also contains some allogenic materials, we can say that the inside of human body all substances nearly all can show in saliva to some extent.Therefore, can diagnose internal environment of oral cavity and salivary gland function by checking saliva, and diagnose some general, metabolic disease, can also realize the monitoring of medicine, the emergency treatment check of drug intoxication etc., saliva test is subjected to medical treatment day by day, detects the unit attention.

Still there is not regular saliva harvester in the market, that have even only alternative with cotton swab, be easy to cause the testing result deviation.

Summary of the invention

The purpose of this utility model provides a kind of double head saliva collector, has easy and simple to handlely, and sampling quantity is big and evenly, prevents the function of sample cross-contamination simultaneously.

The technical scheme that shortcoming adopted that this utility model solves the saliva harvester is: the saliva harvester totally covers three parts by sampling rod, cylinder-form main tube and outlet to be formed; Cylinder-form main tube top is injection port, between sampling rod and the injection port for being threaded; The cylinder-form main tube foot is an outlet, also is connected threadably between outlet and the outlet lid.Sampling rod is made of cotton three structures of loam cake, plunger and imbibition.Loam cake and plunger connected mode are for pegging graft, and plunger and imbibition cotton utilize the bonded adhesives bonding.One conoid protuberance is arranged at outlet lid bottom, cooperates with the taper concave surface of sample outlet position, seals.Loam cake, cylinder-form main tube, lower cover are made by transparent plastic, and the imbibition cotton is made by the material of adsorbable liquid.Sampling rod is put into cylinder-form main tube from injection port, and being responsible for inside is the tubular cavity, turns on the outlet lid, and extruding is over against person in charge's outer wall of sponge, and fluid sample oozes by outlet.

The beneficial effects of the utility model are simple in structure small and exquisite, are easy to make, and are easy to transportation, easy operating; Good seal can not occur leaking when pressurized and sampling; It is more easy to operate that the design of screw thread outlet lid is broken the formula outlet off with the fingers and thumb than common hands, and the threaded together lid can also prevent sample contamination after sampling.

Description of drawings

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

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

Fig. 2 is the section decomposition view of an embodiment of the present utility model.

1. loam cakes among the figure, 2. plunger, 3. imbibition cotton, 4. sampling rod, 5. injection port, 6. cylinder-form main tube, 7. outlet, 8. outlet lid

Specific embodiment

At when sampling twist-off closure at first, sampling rod sponge end is put into mouth, make it speckle with saliva sample, the sampling rod that speckles with saliva is reentered into cylinder-form main tube, tightens bottle cap, turn on the outlet lid, the person in charge of extruding harvester, sample can ooze from outlet, is used for detecting.

Fig. 1 has represented an embodiment outside drawing of the present utility model in detail, and this utility model comprises sampling rod (4), cylinder-form main tube (6) and outlet lid (8).

When sampling, at first imbibition cotton (3) end of sampling rod (4) is put into mouth, draw saliva sample, the sampling rod (4) that speckles with saliva is put into cylinder-form main tube (6), guarantee in this process that outlet lid (8) closes all the time.Tighten loam cake (1), turn on outlet lid (8), extruding is over against person in charge's outer wall of sponge, and fluid sample oozes by outlet.Outlet can be equipped with testing tool (for example detecting reagent paper etc.), also can use supporting detection jam.

Fig. 2 has showed the section decomposition view of an embodiment of the present utility model, and the conoid protuberance of outlet lid bottom as we can see from the figure also can be seen contacting between cylinder-form main tube inwall and the sampling rod (4).

Claims
