Contain the oral mucosa exfoliative cyte in the human saliva, collecting saliva has following advantage as the dna sample source: 1. do not have puncture, do not have the injury sampling, avoided the misery of blood sampling and the embarrassment of getting urine; 2. some crowds are not suitable for blood sampling, as child, old man.Other crowds then resist and get blood, as some psychiatric patient, and patient's relatives; 3. simple and easy to do, saliva collection only needs centrifuge tube: 4. cheap, efficient, do not need to be equipped with syringe, sterilization apparatus, and also need not train the blood drawing personnel of specialty. saved a large amount of manpower and materials; Even the room temperature through 2 weeks is deposited, still can extract complete genomic DNA.When collecting sample on a large scale, saliva sample is adapted at transmitting between the laboratory of each department and the bleeding point.
Many saliva harvesters are also arranged at present on the market, but most of what adopt is to get urine cup or sanitary cup as container, such container bore is bigger, is difficult to seal well and transport, and especially is not suitable for the collecting cassette transportation of large sample amount specimen.At present, scrape the harvester of getting oral mucosa with the cotton swab scraper in addition, the cotton swab sterilization of such harvester may be because of the potential safety hazard that becomes not up to standard; Its two, scraper is scraped and is got oral mucosa and very easily cause the damage of oral cavity inwall, especially to young child or baby; Its three, cotton swab scrapes that to get the sample size that oral mucosa can provide less, may the molecular biological analysis in later stage be impacted.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of saliva harvester that can store fixative is provided.
This utility model adopts following technical scheme to solve the problems of the technologies described above:
A kind of saliva harvester that can store fixative, the collection tube gag that comprises collection tube and match with collection tube is characterized in that, this saliva harvester also comprises the collection funnel with the collection tube pivot bush unit.
Preferable, described collection funnel comprises fixedly connected collection infundibular body and gathers filler neck, and the external diameter of described collection filler neck is less than the spout diameter of collection tube.
Preferably, the external diameter of described collection filler neck is than the little 1～2mm of spout diameter of collection tube.
In use, the saliva fixative directly is contained in the collection tube, with the sealing of collection tube gag.Gather the lower end of funnel and can directly insert the collection tube inwall, tighterly thickly combine.The shape and the blood taking tube of collection tube are basic identical, and gag is used for sealing collection tube, prevent saliva seepage and pollution.
For the technical scheme that shortcoming adopted that overcomes other saliva harvesters is: the saliva harvester mainly is made up of three parts: collection tube, collection tube gag and collection funnel.The saliva fixative directly is contained in the collection tube, with the sealing of collection tube gag.Gather the lower end of funnel and can directly insert the collection tube inwall, tighterly thickly combine.The shape and the blood taking tube of collection tube are basic identical, and gag is used for sealing collection tube, prevent saliva seepage and pollution.
When gathering saliva, to gather the funnel lower end and insert collection tube, saliva supplier's saliva flows into collection tube through funnel, to gather funnel removes, cover tight collection tube gag, collection tube is turned upside down for several times, saliva and fixative mix homogeneously, with the collection tube incidental valve bag of this harvester of packing into, gatherer process finishes.
Compare with existing saliva harvester, the advantage that the utlity model has is:
1. simple in structure, easy to use;
2. can store the saliva fixative, collection can reach the fixedly purpose of saliva after finishing, and prevents to cause saliva sample to pollute or corruption because of haulage time is long;
3. acquisition method is simple, and human body is not had wound, and need not professional training and can finish sample collection;
4. gather funnel lower end and collection tube gag and contact closely, guarantee sample leakage and pollution can not take place in collection and the transportation with collection tube;
5. saliva sample can prevent to pollute after fixative is handled, and can under the prerequisite that does not influence the genome DNA extraction effect pot-life be prolonged greatly;
