The degree to which the sample meets the standard to be tested is affected by the clinical operation level and the cervical cell collection device.

[0003] At present, cervical cell collection devices have certain drawbacks. Since cervical cell sampling needs to be carried out at the squamous-columnar junction and the transformation zone, and the specific locations of the two sites are not fixed, the current collection equipment is directly held by the physician and delivered to the selected locations of the squamous-columnar junction and the transformation zone. The physician then needs to control the collector to lightly wipe the sampling site, but the amount of sample obtained in this process is small.

[0066] The outer end of the internal transmission shaft of the motor 240 is provided with a pre-installed notch;

[0067] The sampling auxiliary mechanism 300 includes a secondary sleeve 310, the inner wall of the secondary sleeve 310 is provided with an annular slideway, and a plurality of locking components 370 evenly distributed in a circumference are arranged in the annular slideway, a limiting inner ring 360 and a clamping component 340 arranged inside the secondary sleeve 310 are arranged on the inner side of the plurality of locking components 370, and a plurality of cotton swabs 500 are arranged in the plurality of locking components 370 and the clamping component 340;

[0068] A linkage member 350 is movably installed inside the clamping assembly 340, and a gear plate is provided at the inner end of the linkage member 350;

[0069] The sample liquid extraction mechanism 400 includes a drainage scraper 460 and a plug 410 disposed inside the limiting inner ring 360;

[0070] A liquid storage bin 420 is arranged inside the plug 410, a sealing gasket 430 is arranged at the other end of the plug 410, a distance adjustment component 470 is arranged inside the liquid storage bin 420, a position control plug 480 is arranged outside the distance adjustment component 470, a slide rail 440 is installed on the inner wall of the liquid storage bin 420, and a compression spring 450 is installed in the inner cavity of the slide rail 440;

[0072] Things to note when sampling cervical cells: (1) 3 to 4 days after the end of menstruation. The best time to sample is in the second half of the menstrual cycle, when endometrial cells shed less and interfere less with cervical cytology. (2) Sampling cannot be performed in the case of severe cervicovaginal inflammation, and anti-inflammatory treatment should be given first. (3) Sampling cannot be performed during menstruation. (4) Sampling during pregnancy should be performed with caution. (5) Sampling cannot be repeated in a short period of time, and sampling should be performed again at least 2 months later.

[0073] When the above conditions are met, the physician needs to hold the collector toward the transformation zone TZ as the collection position, then move the collector close to the junction of the squamous column SCJ, and take samples from the cervical vagina, cervical canal and suspicious areas. However, the existing collectors are manually controlled by the physician and have many disadvantages. Among them, the physician's hand shaking will cause excessive pressure on the affected area, which may easily cause the patient to feel pain and other discomfort. At the same time, the accuracy of the physician's hand-held operation is poor, and the cotton swab is easy to contact the skin outside the sampling, which will affect the subsequent detection. In addition, due to the influence of operation proficiency, the effectiveness of collecting cervical cells with cotton swab is low.

[0074] To this end, the device uses the center position of the rear end of the bed as a precise load-bearing control platform, and adjusts the height of the beam arm 180 and the length of the horizontal movement of the ranging beam rod 210 by adjusting the first bolt 120 and the third bolt 190 respectively. At this time, the propulsion mechanism 200 constrained in the horizontal direction by the beam arm 180 will not shake as a whole during the horizontal movement;

[0075] When the multiple cotton swabs 500 evenly distributed inside the multiple sets of thickened washers 372 enter the designated sampling site along with the sample liquid extraction mechanism 400 as a whole, the doctor can tighten the third bolt 190 and then start the switch 250. At this time, the driven linkage 350 will control the evenly distributed multiple cotton swabs 500 to rotate according to the assembly method of the bracket 341.

[0076] When the patient's affected part has less fluid accumulation, the bracket 341 needs to be fixed in the secondary sleeve 310, and the multiple cotton swabs 500 linked by the multiple gear sleeves 343 can rotate, and the cell samples of each area of ​​the affected part can be collected independently.

[0077] When the patient has a lot of fluid accumulation in the affected area, the bracket 341 needs to be fixed on the linkage 350 and movably installed in the secondary sleeve 310. At this time, multiple cotton swabs 500 can be placed around the affected area until the cell samples are wiped on each cotton swab 500.

[0078] The above operation can reduce the patient's discomfort while improving the effectiveness of cervical cell collection, and can also avoid the initial contact between the cotton head and the skin due to the doctor's hand shaking.

[0079] Embodiment 2:

[0080] Combination Figure 1 , Figure 6 and Fig.12 As shown, based on Example 1, the sampling auxiliary mechanism 300 also includes two protective tubes 320 arranged inside the auxiliary sleeve 310, a disposable soft pad 330 arranged on the end of the auxiliary sleeve 310 away from the ranging beam 210, and a pin 380 arranged inside the linkage 350.

[0081] Preferably, each time the latch 380 fixes the linkage 350 and the plug 410, it is mainly used to provide bearing pressure for the rotation of the progressive screw 472. After the progressive screw 472 is adjusted, the latch 380 is selected to be assembled according to the requirements of the cotton swab 500's rotation and rotation.

[0082] The protective tube 320 is attached to the upper end of the linkage member 350 and has a slot for guiding the end of the plug pin 380;

[0083] The clamping assembly 340 includes a bracket 341 , which is in a T-shaped structure as a whole. The bracket 341 is provided with pressure pads distributed in a circumference, and the groove inside the pressure pad is provided with a bearing 342 and a gear sleeve 343 installed in the bearing 342 .

[0084] Preferably, the clamping assembly 340 shown in the figure is assembled with the auxiliary sleeve 310 and the linkage member 350 by bolt assembly. According to the different conditions of fluid accumulation in the affected part of the patient, the clamping assembly 340 can be selectively fixed on the auxiliary sleeve 310 or the linkage member 350 by bolts.

[0085] The teeth on the outside of the gear shaft sleeve 343 are adapted to mesh with the gear plate on the inner end of the linkage member 350 .

[0093] The thickened gasket 372 may be made of silicone, rubber or a flexible material.

[0096] Preferably, one end of the plug 410 away from the secondary sleeve 310 extends beyond the cotton swab 500. When the plug 410 and the multiple cotton swabs 500 are extended into the interior of the affected part, the portion of the plug 410 that extends beyond the cotton swabs 500 will be compressed when the muscles of the affected part are contracted. At this time, the pin 380 is not inserted into the linkage 350 and the plug 410. When the bracket 341 is fixed to the linkage 350, as the linkage 350 rotates, the multiple gear sleeves 343 drive the multiple cotton swabs 500 to rotate, and excessive accumulated fluid will be scraped off and gathered by the drainage scraper 460.

[0097] The distance adjustment component 470 includes an anti-seepage tube 471 , a slideway is provided inside the anti-seepage tube 471 , and a progressive screw 472 and a suspension 473 provided on the threaded section of the progressive screw 472 are provided in the slideway inside the anti-seepage tube 471 .

[0098] Preferably, the free rotation adjustment of the progressive screw 472 can drive the suspension 473 and the control plug 480 to selectively extend. At this time, the constrained drainage scraper 460 can set the height according to the specifications of the cotton head of the cotton swab 500, thereby improving the scraping efficiency of the accumulated fluid.

[0099] The position control plug 480 is installed on the two ends of the suspension 473, and the position control plug 480 is in a truncated cone structure as a whole;

[0100] The inclined surface at the bottom end of the drainage scraper 460 is adapted to fit the inclined surface on the outside of the position control plug 480 .

[0101] Preferably, the arc-shaped end at the top of the drainage scraper 460 can avoid damaging the cotton tip of the cotton swab 500, and the orientation of the notch of the drainage scraper 460 is used to adapt to the clockwise rotation of multiple cotton swabs 500, thereby improving the extraction rate of the accumulated fluid.

[0102] Embodiment 5:

[0103] Combination Figure 1 and Fig. 9 As shown, in the above embodiment, the direction of the drainage scraper 460 is different according to the condition of the fluid accumulation in the patient's affected part. When the plug 410 and the multiple cotton swabs 500 rotate simultaneously, there is no need to worry about the entire sample liquid extraction mechanism 400.

[0104] The surface material of the plug 410 needs to be selected according to the usage requirements.

[0105] The working principle and use process of the present invention are as follows: the second bolt 130 is loosened in advance, and then the expanded clamp 110 and the pressure pad 140 are clamped at the center of the tail end of the bed, and then the second bolt 130 is tightened, and then the patient is allowed to lie flat on the bed, and at this time, the clamp 110 is facing the middle of the patient's legs;

[0106] Then use tweezers to take out the latch 380, and then insert the plug column 410 into the socket at the inner end of the linkage 350. At this time, the limiting inner ring 360 will clamp and press the plug column 410, and then adjust the progressive screw 472 to rotate counterclockwise until the suspension 473 is delivered outward, and the control plug head 480 installed on the two ends of the suspension 473 will extend outward along the outside of the anti-seepage tube 471. At this time, the drainage scraper 460 is contracted toward the inner cavity of the liquid storage bin 420 by the compression spring 450. At this time, the liquid storage bin 420 can be inserted into the plug column 410 as a whole, and the progressive screw 472 is adjusted clockwise. At this time, the control plug head 480 that contracts toward the inner cavity of the liquid storage bin 420 can squeeze the drainage scraper 460 upward until the port at the top of the drainage scraper 460 penetrates to the outside of the plug column 410;

[0107] When the sample liquid extraction mechanism 400 is pre-installed, tweezers are used to insert multiple cotton swabs 500 along the gap between the plug column 410 and the auxiliary sleeve 310 in sequence until the root of the cotton swab 500 is inserted into the thickened gasket 372 and the gear shaft sleeve 343. At this time, the multiple cotton swabs 500 distributed in a circle can be located outside the plug column 410. According to the distance between the cotton swab 500 and the plug column 410, the progressive screw 472 can be adjusted appropriately until the arc-shaped port at the top of the drainage scraper 460 contacts the cotton head of the cotton swab 500. Each adjustment of the progressive screw 472 requires the latch 380 to be inserted into the linkage 350 until the latch 380 fixes the plug column 410. After the adjustment of the gear lever progressive screw 472 is completed, the latch 380 can be taken out again.

[0108] Then, the pre-installed sampling auxiliary mechanism 300, the sample liquid extraction mechanism 400 and the plurality of cotton swabs 500 are placed in a sterile environment for disinfection. When sampling is required for the patient, the medical staff can take out the above components and install the auxiliary sleeve 310 in the threaded port of the main sleeve 220. At this time, the transmission shaft in the motor 240 can be connected with the other end of the linkage 350, and then the ranging beam 210 is inserted into the rectangular hole at the top of the beam arm 180.

[0109] When in use, the third bolt 190 is initially tightened, and then the first bolt 120 is loosened, and then the beam arm 180 is controlled to drive the above components to rise as a whole until the end of the sample liquid extraction mechanism 400 is level with the patient's sampling site. At this time, the first bolt 120 can be tightened, so that the beam arm 180 provides a stable support platform for the ranging beam rod 210, and then the third bolt 190 is loosened, and then the ranging beam rod 210 is slowly moved horizontally. According to medical sampling regulations, the third bolt 190 can be tightened when the lateral displacement size of the ranging beam rod 210 meets the requirements;

[0110] Then the switch 250 is pressed and the motor 240 is started;

[0111] When the clamping assembly 340 is fixed inside the auxiliary sleeve 310, the driven linkage member 350 can drive the gear plate at its inner end to rotate, and at this time, the multiple gear shaft sleeves 343 evenly distributed in a circle can be linked at a uniform speed, and then drive the multiple cotton swabs 500 evenly distributed to rotate slowly (this process is used for patients with less fluid accumulation in the affected area). After the cotton head of a cotton swab 500 close to the drainage scraper 460 entrains the cells at the sampling site, the cotton head at the rotating location is continuously squeezed and scraped by the top of the drainage scraper 460, and the entrained sample can be uniformly retained in the sealed space formed by the liquid storage bin 420 and the plug 410;

[0112] When the clamping assembly 340 is fixed on the linkage member 350 and movably installed inside the secondary sleeve 310, the plurality of cotton swabs 500 can be rotated as a whole (this process is used for patients with a lot of fluid accumulation in the affected area);

[0113] When the sampling is completed, the multiple cotton swabs 500 can be taken out in sequence using tweezers, and then the entire device can be inverted so that the sample is located in the inner cavity of the plug 410, and then the liquid storage tank 420 can be taken out according to the above operation;

[0114] This process can not only retain a large amount of sample material to be tested at the sampling site, but also centrally retain the sampled material, and conduct multiple measurements in batches to obtain accurate data.

[0115] After the above is completed, the above components can be disinfected and sterilized as required.

[0116] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
