Abstract
The utility model discloses a DNA (Deoxyribonucleic acid) detection sampler, spring one end is fixed to be set up on the urceolus inner wall, and the spring other end is fixed to be set up on the fly leaf, and the button passes that the urceolus is fixed to be set up on the fly leaf, forms the draw -in groove between urceolus and fly leaf, can place liquid sampler in the draw -in groove or the cotton swab of taking a sample, is provided with the gasbag in the draw -in groove and places the department, liquid sampler includes liquid sampling device head, stopper, gasbag, thief rod, and thief rod one end is provided with the liquid sampling device head, and the thief rod other end is provided with the gasbag, is provided with the stopper on the thief rod, distance on the thief rod between stopper and gasbag equals the interior gasbag of draw -in groove and places the distance of locating with the draw -in groove border. The advantage, sample person's hand can not pollute the sample. Adopt liquid sampler to take a sample, the sample back, it is convenient that the sampling probe of sampler changes, and the thief rod of sampler can reuse, and resources are saved reduces medical instrument's use cost.
Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of DNA detection sampler.
Background technology
When detecting DNA, need to detect DNA using sampler sampling.Existing DNA samplings are generally adopted
Cotton swab obtains the mouth epithelial cells of body to be detected, is detected.When holding cotton swab sampling, the hand of sampling person easily pollutes sample
This.Also useful special sampler is sampled, and after sampling terminates, sample-taking brush changes inconvenient, and the thief rod of sampler can not
Recycling, waste of resource increases the use cost of medicine equipment.
Utility model content
For the problem that above-mentioned prior art is present, the utility model discloses a kind of DNA detection sampler.
Its technical scheme is：
A kind of DNA detection sampler, including outer tube, button, portable plate, spring, sampling cotton swab, thief rod, air bag placement
Place, spring one end is fixedly installed on outer tube inner wall, and the spring other end is fixedly installed on portable plate, and button is fixed through outer tube
It is arranged on portable plate, draw-in groove is formed between outer tube and portable plate, liquid sampler or sampling cotton swab, card can be placed in draw-in groove
Air bag lay down location is provided with groove；
The liquid sampler includes liquid dividing head, limited block, air bag, thief rod, and thief rod one end is provided with liquid
Sampling head, the thief rod other end is provided with air bag, and limited block is provided with thief rod；
Distance between the thief rod upper limit position block and air bag is equal to the distance on air bag lay down location and draw-in groove border in draw-in groove.
The DNA for needing detection is sampled using a kind of DNA detection sampler disclosed in the utility model, the doctor of sampling
Shield personnel pin button, the pressure that portable plate is transmitted by button with hand, and spring is subject to the power moved on portable plate, and elastic shape occurs
Become, the formation draw-in groove between outer tube and portable plate is placed into liquid sampler or sampling into the draw-in groove between outer tube and portable plate
Cotton swab, removes the hand for pushing down button, and spring reset, the elastic force of spring pushes down portable plate and is close to outer tube, and portable plate will take with outer tube
The cotton swab bar clamping of sample cotton swab, using sampling cotton swab sampling is completed.
During liquid taking DNA, thief rod is placed in the draw-in groove formed between outer tube and portable plate, due to the thief rod upper limit
Distance between position block and air bag is equal to the distance on air bag lay down location and draw-in groove border in draw-in groove, and the air bag on thief rod can just be put
Put the air bag lay down location in draw-in groove, air bag lay down location be enough to accommodate air bag in draw-in groove, but also can by air bag squeeze it is flat to a certain degree,
When being sampled using the liquid dividing head on thief rod, DNA liquid adhesives after the completion of sampling, are incited somebody to action in the pin-and-hole of liquid dividing head
Take out in draw-in groove of the liquid sampler between outer tube and portable plate, after liquid sampler takes out, air bag is not stressed, air bag becomes
Greatly, can effectively prevent liquid sample from dropping from liquid dividing head.
When a kind of DNA detection sampler provided using the utility model is sampled, the hand of sampling person will not pollute sample.
It is sampled using liquid sampler, after sampling, the sampling head of sampler changes convenient, and the thief rod of sampler can repeat profit
With, economize on resources, reduce the use cost of medicine equipment.

Specific embodiment
As illustrated, a kind of DNA detection sampler, including outer tube 1, button 2, portable plate 3, spring 4, sampling cotton swab 8, take
Sample bar 9, air bag lay down location 10, one end of spring 4 is fixedly installed on the inwall of outer tube 1, and the other end of spring 4 is fixedly installed on portable plate
On 3, button 2 is fixedly installed on portable plate 3 through outer tube 1, and draw-in groove is formed between outer tube 1 and portable plate 3, can be placed in draw-in groove
Liquid sampler or sampling cotton swab 8, are provided with air bag lay down location 10 in draw-in groove；
The liquid sampler includes liquid dividing head 5, limited block 6, air bag 7, thief rod 9, and the one end of thief rod 9 is provided with
Liquid dividing head 5, the other end of thief rod 9 is provided with air bag 7, and limited block 6 is provided with thief rod 9；
