Abstract
The utility model relates to a gene sampler which comprises a sleeve, an ejector rod and a sampling crown, wherein the sampling crown is clamped on the top of the sleeve; a strip-shaped slot is arranged at the tail end of the sleeve; a sliding piece is arranged at the tail end of the ejector rod; the ejector rod is arranged in the sleeve; the ejector rod and the sleeve are arranged with the same center axis and can slide along the center axis; and the sliding piece of the ejector rod penetrates out from the strip-shaped slot of the sleeve. According to the gene sampler, an operator is not contacted with the sampling crown in the gene sampling process, so that the sampling process is free from pollution, and the safety of the operator is guaranteed.
Description
One, technical field:
The utility model relates to the instrument that obtains the DNA gene in the genetically engineered, what be specifically related to is a kind of gene sampling device.
Two, background technology:
Genetically engineered be by with foreign gene by importing in the recipient cell after the vitro recombination, this gene can copy in recipient cell, transcribes, accurate translation thereby make.Genetically engineered be with artificial method with needed a certain donor biology---DNA extraction is out, after in vitro cuts with the proper implements enzyme, it with couple together as the dna molecular of carrier, then import in the recipient cell of a certain easier growth, breeding with carrier, allowing allogenic material copy normally therein and to express, thereby obtain a kind of brand-new technology of new species.
At present, the method that a kind of DNA of obtaining gene is arranged is utilized the cell of swab scraping oral epithelium tissue and is applied on the sheet glass, carries out genetic analysis, but the hand of this method operation cotton balls pollutes easily, moves in the sampling box cotton balls after the sampling also not very convenient.
Three, summary of the invention:
The purpose of this utility model provides a kind of gene sampling device, and this gene sampling device is used for solving the problem that operator might be polluted when obtaining the DNA gene.
The technical scheme that its technical problem that solves the utility model adopts is: this gene sampling device comprises sleeve, push rod, sampling hat, the sampling hat is clamped in the top of sleeve, the end of sleeve is provided with bar-shaped trough, the end of push rod has a slide plate, push rod is arranged in the sleeve, axle setting that push rod and sleeve are concentricity also can be slided along this axle, and the slide plate of push rod passes from the bar-shaped trough of sleeve.
The such scheme middle sleeve is by being with denticulate notch to clamp the sampling hat.
Beneficial effect:
1, the utility model operator in the cdna collection process does not touch with the sampling crown grafting, and sampling process is pollution-free, and is namely convenient safe and reliable again, has guaranteed operator's safety.
2, the utility model is simple in structure, easily makes easy-to-use.
Four, description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of push rod in the utility model.
1 sleeve, 2 push rods, 3 sampling hats, 4 bar-shaped troughs, 5 slide plates.
Five, embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, this gene sampling device comprises sleeve 1, push rod 2, sampling hat 3, sleeve 1 is elongated cylinder, the upper end of sleeve 1 is provided with the notch of little tooth, sleeve 1 is by being with denticulate notch to clamp sampling hat 3, sampling hat 3 is clamped in the top of sleeve 1, and sampling hat 3 can be made with materials such as medical polyster fibre non-woven fabrics, is used for wiping slightly getting oral mucosa epithelial cell; The end of sleeve 1 is provided with bar-shaped trough 4, as shown in Figure 2, the end of push rod 2 has a slide plate 5, slide plate 5 extends laterally from push rod 2, and push rod 2 is arranged in the sleeve 1, and push rod 2 also can slide along this axle with sleeve 1 concentricity axle setting, the slide plate 5 of push rod passes from the bar-shaped trough 4 of sleeve, when upwards promoting slide plate 5, slide plate 5 is up along bar-shaped trough 4, thereby it is interior up at sleeve 1 to drive push rod 2.
When the utility model uses, operator's hat 3 one ends of will sampling stretch in measured's the oral cavity, with sampling hat 3 slightly wiping get the epithelial cell of oral mucosa, finish sampling after, the utility model is moved to the sampling box place, upwards promote the slide plate 5 of push rod, push rod 2 is interior up at sleeve 1, after push rod 2 goes upward to sampling hat 3, the hat 3 of will sampling ejects, after sampling hat 3 breaks away from sleeve 1, drop in the sampling box, thereby finish sampling.
