Description

A kind of saliva collecting device

Technical field

The utility model relates to a kind of acquisition devices, in particular to a kind of saliva collecting device.

Background technique

Saliva has the characteristics that many better than blood and urine, such as acquires simple and convenient, safety, gathered person is easy to receive Deng, be scientific research pass through frequently with one of sample.By being tested and analyzed to salivary component, facilitate to some diseases into Row diagnosis, assesses the physiological function of body, and be monitored to levels of drugs, and by something lost contained in saliva Pass the detection and analysis of substance, moreover it is possible to help to analyze and determine the hereditary capacity of body, therefore saliva in clinical examination and Field of scientific study obtains pay attention to day by day and extensive use.

There are many saliva collecting devices currently on the market, some of them are to use urine cup or sanitary cup as container, But these container bores are larger, it is difficult to seal, be not easy to the transport and preservation of sample.Some are the sides with funnel and collection tube Formula, these major parts are individually stored in reagent in one pipe, are needed independent step that reagent is added, are brought to operator It is inconvenient.

Saliva acquisition method is also in process of experimental at present: cotton column method etc. is chewed in swab stick method and mouth.Wherein, swab stick Method is due to that can cause certain stimulation to the oral cavity of gathered person, so as to cause the change of saliva flow rate, may to chemistry at Analysis has some impact on, less use now.And chewing cotton column method is although convenient and efficient in mouth, gathered person is easy to connect By, but cotton column itself has no chemical component enrichment, and the loss of detection target is be easy to cause in collection process, is eventually led to The reduction of accuracy in detection.Therefore, a kind of pollution-free, painless sampling, acquisition are developed completely and the simple and quick saliva of pre-treatment Liquid acquisition device is particularly significant.

Summary of the invention

The purpose of the utility model is to overcome the above-mentioned problems of the prior art, provide a kind of novel saliva acquisition dress It sets.

To achieve the above object, a kind of saliva collecting device of the utility model adopts the following technical scheme that a kind of saliva Acquisition device, including slot cover, acquisition slot, collection tube and collection tube lid are acquired, it is provided with minimum collection line on collection tube, acquires slot Lid intermediate region is reagent storage area, is provided with plastic film in reagent storage area to seal saliva sample and extract reagent, acquisition Pointed protrusion is provided in slot, acquisition slot cover is connected with acquisition slot, and acquisition slot is connect by spiral way with collection tube, collection tube Lid is used to close collection tube, and minimum line of collecting is used to determine whether the saliva of acquisition is enough.

The acquisition slot cover is connected directly with acquisition slot by flexible connecting member or flexible connector, and can closely be fastened.

Pointed protrusion in the acquisition slot is connected through a screw thread with collection tube.

The collection tube is cylinder, and outer surface is marked with the minimum gathering line.

The collection tube lid and acquisition seal of tube cooperation.

The utility model has the beneficial effects that compared with existing product, the utility model has the advantages that: 1. acquisition slot covers can store up Reagent is deposited, while completing saliva sample acquisition, the pretreatment process of complete paired samples.2. compact structure, easy to use, dry Net health, painless sampling, gathered person are easy to receive.3. being sealed after saliva sample acquisition, sample leakage, pollution are avoided.

Detailed description of the invention

Fig. 1 is a kind of saliva collecting device structural schematic diagram of the utility model.

Specific embodiment

A kind of saliva collecting device of the utility model, as shown in Figure 1, including acquisition slot cover 1, acquisition slot 2, collection tube 3 With collection tube lid 4, minimum 5 five part of collection line is provided on collection tube 3.Acquisition 1 intermediate region of slot cover is reagent storage area, examination Agent is sealed with plastic film, is acquired and is provided with pointed protrusion in slot 2, and acquisition slot cover is connected with acquisition slot, and acquisition slot 2 passes through spiral Mode is connect with collection tube 3, and collection tube lid 1 is used to close collection tube 3, minimum to collect whether line 5 is used to the determining saliva acquired It is enough.Saliva sample is sealed in acquisition slot cover 1 and extracts reagent, and closing is plastic film with film.Acquire slot cover and acquisition slot It is connected directly, and can closely fastened by flexible connecting member or flexible connector.The pointed protrusion acquired in slot is led to collection tube Cross threaded connection.Collection tube is cylinder, and outer surface is marked with the minimum gathering line.Collection tube lid is matched with the acquisition seal of tube It closes.

The formula of reagent be phosphate buffer solution 10-50mmol/L, urea 0.1-2mol/L, SDS0.1-2% (w/v), EDTA1-10mmol/L, ethyl alcohol 2-10% (v/v), Tween-20 0.05-0.5% system pH range is between 6-10.

When acquiring saliva sample, gathered person's discharge saliva flows into collection tube 3 by acquisition slot 2, when saliva sample amount is super When crossing minimum collection line 5, the pressing of acquisition slot cover 1 is covered tightly on acquisition slot 2, the pointed protrusion in slot 2 is acquired and punctures closing examination The plastic film of agent, reagent flow into collection tube 3 along acquisition slot 2, mix with the saliva sample in collection tube 3, from collection tube 3 Acquisition slot 2 is removed, collection tube lid 4 is covered tightly into collection tube 3, collection tube 3 is rocked and mixes reagent and saliva, saliva is completed and acquired Journey.

Embodiment described above is intended merely to further illustrate the utility model, is not intended to limit the utility model, all Within the spirit and principles of the present invention, made any modification, replacement etc., should be included in the protection of the utility model Within the scope of.
