Abstract
The utility model discloses a collection of utensil and saliva, extraction system are extracted to saliva, including saliva collector and saliva extractor, the saliva collector is including collecting the stick and receiving the liquid component, it is fixed in the one end of collecting the stick to receive the liquid component. The saliva extractor includes the liquid storage pipe, draws head and sealed lid, the liquid storage pipe has the open end, it articulates in open end department to draw the head, the one end of drawing the head for sealed end and with the open end forms sealing connection, and its other end is equipped with the dropping liquid head, be equipped with the external screw thread on the outer wall of dropping liquid head, sealed spiro union in the dropping liquid head that covers. Its simple structure, convenient to use has simultaneously to collect and posts the function of drawing.
Description
Technical field
This utility model relates to biochemical sample Acquire and process technical field, particularly relates to the utensil that a kind of saliva sample is collected, extracted.
Background technology
Containing oral mucosa exfoliative cyte in human saliva, collecting saliva has following advantage as DNA or biochemical antibody test samples sources: 1, without puncture, fanout free region sampling, avoid the misery of blood sampling and get the embarrassment of 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 the relatives of patient; 3, simple and easy to do, saliva collection only needs centrifuge tube: 4, cheap, efficient, does not need to be equipped with syringe, sterilization apparatus, also need not train the blood drawing personnel of specialty.Save a large amount of manpower and materials; Even if the room temperature through 2 weeks is deposited, still complete genomic DNA can be extracted.When collecting sample on a large scale, saliva sample is adapted at transmitting between the laboratory of each department and bleeding point.
Also have many saliva collecting devices on the market at present, but major part adopts is get urine cup or sanitary cup as container, such container bore is comparatively large, is difficult to seal well and transport, and is not especially suitable for the collecting cassette transport of large sample amount specimen.At present, also have with the harvester of cotton swab scraper scraping oral mucosa, the cotton swab sterilization of such harvester may become potential safety hazard because of not up to standard; Its two, scraper scraping oral mucosa may cause oral cavity wall to damage, especially to young child or baby; Its three, the sample size that cotton swab scraping oral mucosa can provide is less, may impact the molecular biological analysis in later stage; Its three, only there is acquisition function, not there is abstraction function.
Utility model content
The purpose of this utility model is to provide saliva to extract utensil and collection, extraction system, and its structure is simple, easy to use, has the function of collecting and posting extraction simultaneously.
In order to achieve the above object, the technical solution of the utility model is: saliva extractor, is characterized in that: comprise liquid storage pipe, extract head and seal cover; Described liquid storage pipe has opening, and described extraction head is articulated with open end; One end of described extraction head is sealed end and is formed with described opening to be tightly connected, and its other end is provided with liquid droping head, and the outer wall of described liquid droping head is provided with external screw thread; Described seal cover is bolted in liquid droping head.
Further setting, the inside of described seal cover is provided with the female thread coordinated with external screw thread, is provided with the plug of the drip for blocking described liquid droping head bottom it.
Further setting, described extraction head comprises connecting plate, and described sealed end and liquid droping head are individually fixed in the left and right sides of connecting plate; Described connecting plate is articulated with open end by flexure strip.
Saliva collection, extraction system, comprise saliva collector and saliva extractor; Described saliva collector comprises to be collected rod and receives liquid element, and described receipts liquid element is fixed on the one end of collecting rod.
Further setting, described receipts liquid element is nonmetal cylinder.
The beneficial effects of the utility model are:
1, structure is simple, easy to use, can extract saliva fast;
2, saliva fixative can be stored, gather the object that can reach fixing saliva after terminating, prevent from causing because haulage time is longer saliva sample to pollute or corruption;
3, acquisition method is simple, to human body hurtless measure, and can complete sample collection without the need to professional training;
4, liquid storage pipe can seal, and guarantees to gather and in transportation, sample leakage and pollution can not occur.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model saliva extracts utensil;
Fig. 2 is the structural representation of this utility model saliva collection, extraction system;
Fig. 3 is the structural representation of this utility model saliva collector.
Detailed description of the invention
As shown in Figure 1, saliva extractor 1, comprises liquid storage pipe 11, extracts 12 and a seal cover 13; Described liquid storage pipe 11 has opening 111, and described extraction 12 is articulated with opening 111 place.One end of described extraction 12 is sealed end 121 and is formed with described opening 111 to be tightly connected, and its other end is provided with liquid droping head 122.The outer wall of described liquid droping head 122 is provided with external screw thread; Described seal cover 13 is bolted in liquid droping head 122.The inside of described seal cover 13 is provided with the female thread coordinated with external screw thread, is provided with the plug 131 of the drip for blocking described liquid droping head 122 bottom it.Described extraction 12 comprises connecting plate 123, and described sealed end 121 and liquid droping head 122 are individually fixed in the left and right sides of connecting plate 123; Described connecting plate 123 is articulated with opening 111 place by flexure strip 3.
See Fig. 2-3, saliva collection, extraction system, comprise saliva collector 2 and saliva extractor 1.Described saliva collector 2 comprises to be collected rod 21 and receives liquid element 22, and described receipts liquid element 22 is fixed on the one end of collecting rod 21.Described receipts liquid element 21 is nonmetal cylinder.
Collect and leaching process: people holds collection rod and receipts liquid element 21 is sent in the mouth of people, people spits into saliva and receives in liquid element 21; Open and extract 12, the saliva of receiving in liquid element 21 is poured in liquid storage pipe 11, then take out and receive liquid element 21, the opening 111 of liquid storage pipe 11 is covered with the sealed end 121 extracting 12, finally, open seal cover 13, by liquid droping head 122, saliva is dripped on saliva test panel.
Use the benefit that this utility model has: easy to operate, saliva can be extracted fast; Saliva fixative can be stored, gather the object that can reach fixing saliva after terminating, prevent from causing because haulage time is longer saliva sample to pollute or corruption; Acquisition method is simple, to human body hurtless measure, and can complete sample collection without the need to professional training; Liquid storage pipe can seal, and guarantees to gather and in transportation, sample leakage and pollution can not occur.
