Examples are shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6:

cervical sampler, including hollow handle 4, sliding connection is at inside push rod 8 and the insert tube 9 of hollow handle 4, can dismantle a section of thick bamboo 6 of inserting of being connected with hollow handle 4, can dismantle the protective housing 1 of being connected with an section of thick bamboo 6 of inserting, insert tube 9 passes and inserts a section of thick bamboo 6 and is equipped with the cavernosum 2 that is used for the sampling, the inner wall of inserting a section of thick bamboo 6 is equipped with and blocks piece 601, the both sides of insert tube 9 are equipped with and can block cardboard 10 of inserting a section of thick bamboo 6, one side that insert tube 9 is located cardboard 10 is equipped with and blocks that piece 601 contact just can not influence insert tube 9 pivoted diving board 11.

The specific installation process comprises the following steps:

firstly, as shown in fig. 5, a push rod 8 is fixedly connected with an insertion tube 9, a knob 3 is arranged at the right end of the push rod 8, anti-skid grains are arranged on a hollow handle 4 and the knob 3, in the manufacturing process, the push rod 8, the insertion tube 9 and the knob 3 are integrally formed, the insertion tube 9 and the push rod 8 are enabled to rotate along with the rotation of the knob 3, then, as shown in fig. 5, an action tube 5 is fixedly connected to the left end part of the insertion tube 9, which is far away from the push rod 8, a sponge body 2 is installed on the action tube 5, the sponge body 2 is detachably connected to the action tube 5, the sponge body 2 is used for sampling cervical cells, and the detection is realized by adopting a corresponding detector through liquid or cells on the sponge body 2;

secondly, installing a hollow handle 4, wherein the size of the knob 3 is equal to that of the end part of the hollow handle 4, as shown in figure 2, the hollow handle 4 is sleeved on a push rod 8 and an insertion tube 9, and then the end part is contacted with the knob 3, as shown in figure 2, after the hollow handle 4 is installed, an insertion tube 6 is required to be installed;

with respect to the insert cylinder 6: as shown in fig. 3, a mounting plate 7 is fixedly connected to the right side of the insertion tube 6 close to the hollow handle 4, mounting holes 701 are symmetrically formed in the mounting plate 7, a connecting plate 401 matched with the mounting plate 7 is arranged at the left end of the hollow handle 4, protrusions 402 are arranged on the connecting plate 401, and the number and the positions of the protrusions 402 correspond to the mounting holes 701 one by one.

Specifically, the method comprises the following steps: the connecting plate 401 is fitted with the mounting disc 7 for mounting, and then the protrusion 402 is inserted into the mounting hole 701, the position and structure of the protrusion 402 are shown in fig. 4, and after the cartridge 6 is mounted, as shown in fig. 3, the exposed part is only the residual acting pipe 5;

finally, installation protective housing 1, protective housing 1's shape is the same with the shape of inserting a section of thick bamboo 6, and protective housing 1 is close to the inner wall symmetry rigid coupling of inserting a right side of 6 and has joint piece 101, and the effect end of joint piece 101 is being used in the both sides of inserting a section of thick bamboo 6, and is specific: the clamping block 101 is clamped on the inserting tube 6, when the protective shell 1 needs to be taken down, the clamping block 101 is broken off by hand, the protective shell 1 is separated from the inserting tube 6, and the position and the structure of the clamping block 101 are shown in the attached drawing 3;

the following embodiments will be described in detail with respect to how to use and prevent the insertion tube 9 from backing up:

firstly, when the device is not used, the hollow handle 4 is not in contact with the knob 3, the knob 3 is arranged on the right side of the hollow handle 4, when the device is needed to be used, the knob 3 is pushed by hands, so that the knob 3 with the knob 3 being connected moves leftwards relative to the hollow handle 4, and in the moving process, the acting tube 5 and the sponge body 2 on the acting tube 5 can come out of the inserting tube 6, so that the effect can be realized;

secondly, in the moving process, there is a distance of an upper limit of movement, that is, the knob 3 contacts the hollow handle 4 to stop, after the rotation stops, the snap-gauge 10 in the embodiment starts to function, and as for the snap-gauge 10, the snap-gauge 10 also moves in the insertion tube 6 during the moving process, as shown in fig. 5, one end of the snap-gauge 10 is in a tilted state, the inner wall of the insertion tube 6 is not smooth, and is a step section, when the snap-gauge 10 moves from the insertion tube 6, the inner diameter of the insertion tube 6 changes through the above step section, due to the function of the snap-gauge 10, the insertion tube 9 cannot move backwards, but only moves forwards, but the hollow handle 4 and the knob 3 are released and cannot move forwards, therefore, the position of the insertion tube 9 is fixed, and after the position of the insertion tube 9 is fixed, the positions of the sponge 2 on the action tube 5 and the action tube 5 are also determined, and by this arrangement, the problem that the operation is more complicated due to the retraction phenomenon of the insertion tube 9 in the conventional cervical sampler can be solved.

Third, as for the spring plate 11 and the stopper 601, as shown in fig. 6, when the insertion tube 9 is positioned and the knob 3 is turned by hand as in the second step, the insertion tube 9 can be rotated, but during this rotation, the stopper 601 will contact the spring plate 11, the spring plate 11 will generate elastic force to give the operator a prompt, and as for the prompt part, for example: the sponge body 2 is required to rotate three times in the sampling process, the elastic plate 11 can generate elasticity, and the generated vibration reminds an operator, so that the method is more convenient and suitable than the mode that the operator acquaints three times;

regarding the setting of diving board 11 and barrier 601, diving board 11 adopts the medical grade elastomer preparation to form, and diving board 11 can not influence the rotation of barrier 601, and both are just good contact's state, but, contact back diving board 11 when barrier 601, diving board 11 can have certain elasticity to this elasticity can disappear, utilizes diving board 11 to reset and reminds operating personnel pivoted number of turns.

Finally, regarding sampling: hollow handle 4 is handed to one hand, and knob 3 is handed to the other hand, rotates through knob 3 and makes cavernosum 2 rotate, and then realizes through cavernosum 2 that the adoption of endocervical liquid cell can.

The device solves the problem that the traditional cervical sampler is more complicated to operate due to the retraction phenomenon of the insertion tube 9.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
