Specifically, through setting up baffle 31, can make between the scraper 35 relatively separate, avoid cross infection or the inaccurate condition of assay, through the up-and-down motion of pushing away ball 41, can make the movable block 32 be pushed and move around by pushing away ball 41, through fixing connecting rod 34 on movable block 32, fix scraper 35 and sponge 36 on connecting rod 34, set up logical groove 38 on sample head 4 side scraper 35 and sponge 36 corresponding position, can make the motion of movable block 32 can drive scraper 35 and sponge 36 and stretch to the outside of sample head 3, through set up second spring 33 on the connecting rod 34 of movable block 32 and baffle 31 internal surface, can make can all save in the inside of sample head 4 with sponge 36 and scraper 35 under the condition that the movable block 32 does not receive the extrusion force jointly, avoid producing the pollution with the too much contact in the external world and make the assay degree of accuracy low.
In this embodiment, the lower end of the alcohol cylinder 110 is open, alcohol is contained therein, and the lower end opening is sealed by tinfoil.
The lower surface of the puncture head 12 is fixedly connected with the base 16, and the section of the puncture head 12 is in a diamond shape, namely the middle diameter of the puncture head 12 is larger than the diameter of the lower surface.
The upper surface of the base 16 is conical, and the middle region in contact with the puncture head 12 is higher than the surrounding regions.
It is specific, it is sealed through the tinfoil that sets the opening of a alcohol section of thick bamboo 110 to, can make things convenient for puncture head 12 to open it, through setting the shape of puncture head 12 to the tangent plane rhombus, the intermediate diameter is greater than the lower extreme diameter, can make the tinfoil of an alcohol section of thick bamboo 110 sealed can also leave the outflow of certain space convenience alcohol after being punctured by puncture head 12, through setting the upper surface with base 16 to coniform, can make alcohol all flow to the position of two annular through-hole 14, make things convenient for medical personnel's operation more, the waste of alcohol has been avoided.
The upper part of the outer surface of the sampling head 3 is provided with a thread structure, the inner surface of the second cavity 18 is provided with threads, and the sampling head 3 is in threaded connection with the second cavity 18 of the sampler main body 1 through the upper part of the outer surface.
Specifically, sampler main part 1 and sampling head 4 pass through threaded connection, can be so that both connect more firm, avoid sampling head 4 to drop because of the thrust of propelling ball 41.
The diameter of the push ball 41 is greater than the distance between the opposing movable blocks 32 and ensures that the scraper 35 and sponge 36 are pushed out of the through slot 38 of the sampling head 3.
Specifically, through the reasonable setting of the diameter of the pushing ball 41, the pushing resistance is smaller, the operation of the medical staff is more convenient, and the scraper 35 and the sponge 36 can be pushed out in the most appropriate length, so that the use experience of the medical staff is improved.
The working principle is as follows:
by adding the detachable sampler main body 1 and the sampling head 3 in the device, the sampling head 3 is sealed for disposable use, when medical staff needs to sample and test the pathological change position of a patient, the sealing cover 2 is firstly opened, the alcohol cylinder 110 is pressed into the alcohol tank 11, after the sealing tinfoil of the alcohol cylinder 110 is pierced by the piercing head 12, alcohol flows into the annular through hole 14, the lower end of the annular through hole 14 corresponds to the position of the sponge 36, when the sponge 36 is completely soaked by the alcohol, the sliding rod 43 is pushed, the sliding rod 43 drives the pushing ball 41 to move downwards, the pushing ball 41 extrudes the moving block 32, the moving block 32 moves towards the periphery, the connecting rod 34 is fixedly connected on the moving block 32, the scraper 35 and the sponge 36 are fixedly connected on the connecting rod 34, so the pushing ball 41 can extrude the scraper 35 and the sponge 36 soaked by the alcohol outside of the sampling head 3, the pathological change skin is scraped by the scraper 35, after the scraping, the alcohol sponge 36 with the protruding direction is rotated to disinfect the position, when a plurality of pathological changes are sampled or a plurality of samples are needed, the pushing ball 41 is pushed continuously, so that the pushing ball 41 extrudes the moving block 32 on the next layer to complete the contraction process of the previous scraper 35 and the alcohol sponge 36 and the extending process of the scraper 35 and the alcohol sponge 36 on the next layer. Make the more simple and convenient easy operation of whole sample process through changing reuse and the sterile scraper of needs into disposable sampling head 3, through setting up sponge 36 in the inside of sampling head 3, and be provided with a wine section of thick bamboo 110 and annular through-hole 14 and wet it, make medical staff need not the multi-hand operation or change the medical work operation, through stretching out and retracting that sets up scraper 35, make scraper 35 save the inside at sampling head 3 at non-operating condition always, cross infection has been avoided, the work load of medical staff to pathological change skin sample in-process has been greatly reduced from the angle of difference to above measures.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
