Abstract

The utility model relates to a saliva DNA (deoxyribonucleic acid) sample collector which consists of a collection funnel, a collection pipe and a collection pipe cap, wherein the collection funnel and the collection pipe cap are in threaded connection with the collection pipe respectively; sharp protuberances are arranged on the two sides of an orifice at the upper end of the collection pipe; and a plastic film storing a nucleic acid stabilizer is arranged in the collection pipe cap. When the saliva DNA sample collector is in use, the collection funnel is connected with the collection pipe; and the mouth of the collector aligns to the collection funnel, and then saliva flows into the collection pipe through the collection funnel. After collection, the collection funnel is removed, and the collection pipe cap is tightly screwed on the collection pipe. In the screwing process, the plastic film is punctured by the sharp protuberances on the inner wall at the orifice of the collection pipe, the nucleic acid stabilizer in the plastic film flows into the collection pipe to be mixed with the collected saliva, and the collection pipe is turned upside down to uniformly mix the saliva with the nucleic acid stabilizer. The saliva DNA sample collector realizes painless collection; the nucleic acid stabilizer is safely sealed in the plastic film of the pipe cap; the processes of screwing the cover and enabling the nucleic acid stabilizer to flow out are finished in one step, and the operation is easy and convenient; and the mixture of the saliva and nucleic acid stabilizer can be stored at normal temperature for 3 months.

Description

Saliva dna sample harvester

Technical field

This utility model relates to a kind of saliva dna sample harvester, is specifically related to a kind of dna sample that is used to gather the people, is applicable to genetic analysis and detection, the sample collection of medical test etc.

Background technology

Contain the oral mucosa exfoliative cyte in the human saliva, collect saliva as dna sample because of being not have the injury sampling, simple and easy to do and generally employing.Existing saliva harvester has plenty of with cotton swab gathers saliva, more loaded down with trivial details.

Existing utility model patent " double head saliva collector " (Chinese patent number 200620123835.7) covers three parts by the sampling rod that is threaded, cylinder-form main tube and outlet and forms.Sampling rod is made up of cotton three structures of loam cake, plunger and imbibition.During sampling, the cotton end of sampling rod imbibition is put into mouth, make it be stained with saliva sample, again sampling rod is reentered into cylinder-form main tube, tighten bottle cap, turn on out the appearance lid, squeeze out sample.With the cotton collected specimens of imbibition, be prone to pollute, and complex operation." saliva harvester " (Chinese patent number 201020215405.4), the collection tube gag that comprises collection tube and match with collection tube also comprises the collection funnel with the collection tube pivot bush unit.The saliva fixative directly is contained in the collection tube, seals with the collection tube gag.When gathering saliva; To gather the funnel lower end and insert collection tube, saliva supplier's saliva flows into collection tube through funnel, will gather funnel and remove; Cover tight collection tube gag; Collection tube is turned upside down for several times, with saliva and fixative mix homogeneously, with the collection tube incidental valve bag of this harvester of packing into.Be prone to cause nucleic acid stability agent volatilization, mix inhomogeneously, inconvenience such as leak in the use.Also have and do a filler cap separately, the nucleic acid stability agent is deposited in the filler cap, like the OG-500 of OrageneDNA production, but in use, the lid that before not gathering saliva at the beginning, will preserve the nucleic acid stability agent easily crushes, and does not have safeguard procedures.

Summary of the invention

The purpose of this utility model is to above-mentioned present situation, aim to provide a kind of simple in structure, do not had any discomfort sense by the picker, convenient and healthy, long saliva dna sample harvester of holding time at normal temperatures.

The implementation of this utility model purpose does; Saliva dna sample harvester; By collection funnel, three parts of collecting pipe and collection pipe cap are formed, and collection funnel, collection pipe cap are threaded with collecting pipe respectively; There is sharp projection the both sides of mouth of pipe place, collecting pipe upper end inwall, collect the built-in sealing of pipe cap and preserve the plastic sheeting of nucleic acid stability agent.

During use, earlier collection funnel and collecting pipe are coupled together, aimed at collection funnel by picker's face, saliva flows in the collecting pipe through collection funnel.After saliva collection is intact, unload collection funnel, will collect pipe cap and be screwed on the collecting pipe, and tighten.In the process of tightening, the sharp projection that the plastic sheeting that the nucleic acid stability agent is preserved in sealing is collected pipe inwall both sides, mouth of pipe place punctures, and the nucleic acid stability agent meeting that sealing is preserved in the plastic sheeting flows in the collecting pipe along tube wall, mixes with saliva.After tightening sealing fully, put upside down collecting pipe, make saliva and nucleic acid stability agent mix homogeneously.

This utility model has following advantage:

1, simple in structure, good looking appearance, advantages of small volume are convenient to transportation;

2, painless collection, tool invasion property is not had any discomfort sense by the picker, and is convenient and healthy;

3, the nucleic acid stability agent is deposited in the plastic sheeting of gathering in the pipe cap, not only safety but also save material;

4, the single stepping completion is flowed out in screw capping, nucleic acid stability agent, and simple to operation, the picker can not make saliva and nucleic acid stability agent not mix because of forgeing, and can preserve 3 months at normal temperatures after the mixing.

This utility model is for replacing blood sample to provide than good tool with saliva sample.

Description of drawings

Fig. 1 is the structure side figure of this utility model,

Fig. 2 is collecting pipe and collection pipe cap installation diagram,

Fig. 3 is that the C-C of Fig. 2 is to profile.

The specific embodiment

With reference to Fig. 1, this utility model is by

collection funnel

1, and 3 three parts of collecting pipe 2 and collection pipe cap are formed.Collection funnel 1 is threaded with collecting pipe 2, and collecting pipe 2 is threaded with collection pipe cap 3, collects the nucleic acid stability agent that has the plastic sheeting sealing to preserve in the pipe cap 3.The wine cup in shape similar ancient times of collection funnel 1, good looking appearance, and mouthful big makes adopter's face aim at collection funnel, tool invasion property, painless collection is not had any discomfort sense by the picker, and is convenient and healthy.

During use, earlier collection funnel 1 and collecting pipe 2 are coupled together.Aimed at collection funnel by picker's face, saliva flows in the collecting pipe through collection funnel.After saliva collection is intact, unload collection funnel, the collecting pipe lid is screwed on the collecting pipe, and tightens, become Fig. 2, state shown in 3.In the process of tightening, the sharp projection 4 that the plastic sheeting that the nucleic acid stability agent is preserved in sealing is collected pipe inwall both sides, mouth of pipe place punctures, and the nucleic acid stability agent meeting that sealing is preserved in the plastic sheeting flows in the collecting pipe along tube wall, mixes with saliva.After tightening sealing fully, put upside down collecting pipe, make saliva and nucleic acid stability agent mix homogeneously.

The painless collection of this utility model; The nucleic acid stability agent in plastic sheeting, safety; Step completion is flowed out in screw capping, nucleic acid stability agent, and is simple to operation; Saliva and nucleic acid stability agent can be preserved 3 months after mixing at normal temperatures.
