Description

Technical Field

[0001] The present invention relates to the technical field of cervical cell collection, and specifically to a cervical cell self-collection device. Background Technique

[0002] In the quality control of cervical cytology examination, sampling is the first element. Clinicians need to understand the criteria for satisfactory and unsatisfactory specimens in cervical cytology examination to evaluate whether the sampling is qualified. The standard degree of the sampling object to be tested is affected by the clinical operation level and the cervical cell collection device.

[0003] At present, there are certain drawbacks in the cervical cell collection device. Since cervical cell sampling needs to be carried out at the squamous-columnar junction and the transformation zone, and the specific positions of collection at the two parts are not fixed. Currently, the collection device is directly held by the physician and delivered to the selected positions at the squamous-columnar junction and the transformation zone. Then, the physician needs to control the collector to gently wipe the sampling site. However, the amount of the sampling object obtained in this process is small. Also, due to the hand-held operation, once the collector shakes during insertion, the sampling site contacting the skin first will affect the detection of the subsequent sampling object.

[0004] In view of this, a cervical cell self-collection device is designed to solve the above problems. Summary of the Invention

[0031] By adopting the above technical solutions, the beneficial effects obtained by the present invention are:

[0032] 1. The present invention provides a sampling-assisting mechanism, and a plurality of cotton swabs are evenly distributed around the circumference of the sampling-assisting mechanism. When the sampling-assisting mechanism controls the evenly distributed cotton swabs to penetrate the sampling site, the slowly assisted rotation of the plurality of cotton swabs can evenly wipe the affected area. At this time, a large number of target objects to be tested can be obtained from the affected area in a single collection operation, thereby eliminating the need for manual control of the collector to wipe the affected area and obtain a sufficient amount of cell samples to be tested, thereby improving the accuracy of subsequent comparative testing.

[0033] 2. The present invention arranges a sample liquid extraction mechanism in the sampling auxiliary mechanism. Since the wetness of the affected parts of different patients is different, when a large amount of fluid accumulates during the wiping process of the above-mentioned multiple evenly distributed cotton swabs, the drainage scraper can slowly scrape the accumulated fluid around the cotton swabs into the plug and the liquid storage tank. As the accumulated fluid is scraped off, the multiple evenly distributed cotton swabs can wipe the surface of the affected part, thereby effectively avoiding the influence of the patient's body fluid on cell collection. At the same time, the stored accumulated fluid can also provide a comparison sample for subsequent secondary detection.

[0034] 3. The present invention sets the anti-shake calibration mechanism at the center of the tail end of the bed, assembles the propulsion mechanism in the anti-shake calibration mechanism, and adjusts the propulsion spacing of the propulsion mechanism according to the depth of penetration into the affected part required for medical examination. At this time, the device can be prevented from shaking during sampling, and thus will not cause a series of discomfort to the patient due to movement. At the same time, the non-shaking device can improve the effectiveness of collecting cervical cells from the affected part. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0055] The following describes a cervical cell self - collection device provided by some embodiments of the present invention with reference to the accompanying drawings.

[0056] Example 1:

[0057] Combined Figures 1-12 As shown, a cervical cell self - collection device provided by the present invention includes a plurality of cotton swabs 500, an anti - shake calibration mechanism 100 arranged at the tail end of the hospital bed and located at the central position of the tail end, a propulsion mechanism 200 arranged inside the anti - shake calibration mechanism 100, a sampling assisting mechanism 300 arranged on the propulsion mechanism 200, and a sample liquid extraction mechanism 400 arranged inside the sampling assisting mechanism 300. The plurality of cotton swabs 500 are evenly distributed in a circular shape outside the sample liquid extraction mechanism 400. The anti - shake calibration mechanism 100 is used to provide a anti - shake support platform for the propulsion mechanism 200 and improve the effectiveness of collecting cervical cells. The propulsion mechanism 200 is used to provide unified rotational kinetic energy for the evenly distributed plurality of cotton swabs 500. The sampling assisting mechanism 300 is used to drive the plurality of cotton swabs 500 to rotate.

[0058] The anti - shake calibration mechanism 100 includes a chuck 110 clamped on the hospital bed. A beam arm 180 is movably installed inside the chuck 110, and a rectangular hole is opened at the top end of the beam arm 180;

A spring 160 is arranged outside the guide rods 150, and the two guide rods 150 are movably installed inside the chuck 110, and the top ends of the two springs 160 are pressed against the bottom of the chuck 110;

[0063] Anti - slip pads 170 are arranged at the top inside the chuck 110 and at the top of the pressure pad 140;

[0064] The propulsion mechanism 200 includes a ranging beam rod 210 movably installed in the rectangular hole. The ranging beam rod 210 is composed of an extended rectangular end rod and an oval handle, and a scale is arranged at the top of the extended rectangular end plate;

[0065] A main sleeve 220 is installed on the ranging beam rod 210, an energy supply component 230 and a motor 240 arranged inside the main sleeve 220, and a switch 250 arranged on the motor 240;

[0066] A pre - installation notch is provided at the outer end of the internal transmission shaft of the motor 240;

[0067] The sampling assisting mechanism 300 includes a secondary sleeve 310. An annular slideway is provided on the inner wall of the secondary sleeve 310, and a plurality of locking components 370 evenly distributed in a circumferential manner are arranged in the annular slideway. An inner limiting ring 360 and a clamping component 340 arranged inside the secondary sleeve 310 are provided inside the plurality of locking components 370. 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 component 340, and a gear disk 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 column 410 arranged inside the inner limiting ring 360;

[0070] A liquid storage chamber 420 is provided inside the plug column 410, a sealing gasket 430 is provided at the other end of the plug column 410, an adjusting distance component 470 is provided inside the liquid storage chamber 420, a position - controlling plug head 480 is arranged outside the adjusting distance component 470, a slide rail 440 is installed on the inner wall of the liquid storage chamber 420, and a compression spring 450 is installed in the inner cavity of the slide rail 440;

[0071] The end plate of the drainage scraper 460 penetrating into the inner cavity of the liquid storage chamber 420 is movably installed in the chute inside the slide rail 440, and the bottom end of the compression spring 450 bears on the plate surface of the drainage scraper 460 penetrating into the chute.

[0072] Attention should be paid to the following when taking cervical cell samples: (1) After 3 - 4 days of the end of menstruation, the best sampling time is the second half of the menstrual cycle. The shedding of endometrial cells is less, and the interference with cervical cytology examination is less; (2) When there is severe cervicovaginal inflammation, sampling cannot be performed, and anti - inflammatory treatment should be carried out first; (3) Sampling cannot be performed during menstruation; (4) Sampling during pregnancy should be cautious; (5) Sampling cannot be repeated in the short term, and sampling should be carried out again at least 2 months later;

[0073] After the above conditions are met, the doctor needs to hold the collector towards the transformation zone TZ as the sampling position, then bring the collector close to the squamocolumnar junction SCJ, and take samples considering the vaginal part of the cervix, the cervical canal and the suspicious parts. However, there are many drawbacks in the existing collector controlled manually by the doctor. Among them, the shaking of the doctor's hand will cause too much pressure on the affected part, which is likely to make the patient feel pain and other discomfort. At the same time, the accuracy of the doctor's hand - held operation is poor, and the cotton swab is likely to contact the skin outside the sampling area, which will affect the subsequent detection. In addition, due to the influence of operation proficiency, the effectiveness of the cotton swab in collecting cervical cells is low.

[0074] To this end, the device uses the central position at the end of the hospital bed as an accurately loaded position control platform. By adjusting the first bolt 120 and the third bolt 190, the height of the beam arm 180 rising and the length of the ranging beam rod 210 moving horizontally are respectively adjusted. At this time, the overall propulsion mechanism 200 constrained by the beam arm 180 in the horizontal direction will not shake during the horizontal movement;

[0075] When multiple cotton swabs 500 evenly distributed inside multiple thickened washers 372 enter the designated sampling site along with the overall sample extraction mechanism 400, 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 there is less fluid accumulation in the patient's affected area, the bracket 341 needs to be fixed inside the secondary sleeve 310, and the multiple cotton swabs 500 linked by multiple gear bushings 343 can rotate on their own. At this time, the cell samples in each area of the affected area can be independently collected;

[0077] When there is more fluid accumulation in the patient's affected area, the bracket 341 needs to be fixed on the linkage 350 and movably installed inside the secondary sleeve 310. At this time, the multiple cotton swabs 500 can surround the affected area until the cell samples are wiped on each cotton swab 500;

[0078] The above operations can reduce the discomfort of the patient, improve the effectiveness of cervical cell collection, and avoid the initial contact between the cotton head and the skin caused by the doctor's hand shaking.

[0079] Embodiment 2:

[0080] Combined with Figure 1 、 Figure 6 and Figure 12 As shown, on the basis of Embodiment 1, the sampling assisting mechanism 300 further includes two protecting tubes 320 arranged inside the secondary sleeve 310, a disposable soft pad 330 arranged at one end of the secondary sleeve 310 away from the ranging beam rod 210, and a plug pin 380 arranged inside the linkage 350.

[0081] Preferably, each fixation of the plug pin 380 to the linkage 350 and the plug post 410 is mainly used to provide a bearing pressure for the rotation of the progressive screw 472. After the progressive screw 472 is adjusted, the plug pin 380 is selected for assembly according to the requirements of the rotation and surrounding of the cotton swab 500.

[0082] The port of the protecting tube 320 attached to the linkage 350 is provided with a notch for guiding the end of the plug pin 380;

[0083] The clamping assembly 340 includes a bracket 341. The bracket 341 is integrally in a T-shaped structure, and pressure-bearing pads are arranged on the bracket 341 in a circumferential distribution. A bearing 342 and a gear bushing 343 installed in the bearing 342 are arranged in the slot inside the pressure-bearing pad.

[0084] Preferably, the assembly method of the clamping assembly 340, the secondary sleeve 310 and the linkage 350 in the figure is by bolt assembly. According to the fluid accumulation condition of the affected part of different patients, the clamping assembly 340 can be selectively fixed on the secondary sleeve 310 or the linkage 350 through bolts.

[0085] The tooth openings on the outside of the gear bushing 343 are adaptively meshed with the gear disk at the inner end of the linkage 350.

[0086] Preferably, the number of the locking assemblies 370 is the same as the number of the gear bushings 343, and a cushion layer for increasing the frictional resistance with the cotton swab 500 is arranged on the inner hole wall of the gear bushing 343.

[0087] Embodiment 3:

[0088] Combined with Figure 11 As shown, on the basis of Embodiment 1, the locking assembly 370 includes a swivel joint 371 and a thickened washer 372 installed inside the swivel joint 371;

[0089] On one side of the outside of the swivel joint 371, two clamping plates are installed, and a shaft rod is arranged inside the two clamping plates. On the other side of the outside of the swivel joint 371, a chuck is installed;

[0090] The thickened washer 372 is made of thickened silica gel material, and the thickened washer 372 is integrally in an I-shaped structure;

[0091] Through holes are opened in both the thickened washer 372 and the gear bushing 343, and a thickened washer 372 and a gear bushing 343 which are symmetrically distributed are used to fasten a cotton swab 500.

[0092] Preferably, the materials of the swivel joint 371 and the limiting inner ring 360 are not unique. The limiting inner ring 360 is mainly used to provide double constraints for multiple swivel joints 371 in cooperation with the annular sliding groove on the inner wall of the secondary sleeve 310, and the limiting inner ring 360 is mainly used to lock the plug 410;

[0093] Among them, the thickened washer 372 can be made of silica gel, rubber or flexible material.

[0094] Embodiment 4:

[0095] Combined with Figures 5-12 As shown, on the basis of Embodiment 1, a guide rod is arranged at the inner end of the plug 410, uniformly distributed jacks are opened in the guide rod, and the guide rod is adaptively penetrated into the hole at the inner end of the linkage 350.

[0096] Preferably, one end of the plug post 410 away from the auxiliary sleeve 310 extends beyond the cotton swab 500. After the plug post 410 and multiple cotton swabs 500 extend into the affected part, the part of the plug post 410 extending beyond the cotton swab 500 will be pressed by the tightened state of the muscles of the affected part. At this time, the pin 380 is not inserted into the linkage 350 and the plug post 410. When the bracket 341 is fixed to the linkage 350, with the rotation of the linkage 350, multiple gear sleeves 343 drive multiple cotton swabs 500 to rotate, and excessive effusion will be scraped and collected by the drainage scraper 460.

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

[0098] Preferably, the free rotation adjustment of the progressive screw 472 can drive the suspension 473 and the position 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 heads of the cotton swabs 500, thereby improving the scraping efficiency of the effusion.

[0099] The position control plug 480 is installed at both ends of the suspension 473, and the position control plug 480 is integrally in a frustum shape;

[0100] The inclined surface at the bottom end of the drainage scraper 460 is adaptively fitted to 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 heads of the cotton swabs 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 effusion.

[0102] Embodiment 5:

[0103] Combined with Figure 1 and Figure 9 As shown, in the above embodiment, according to the effusion situation of the patient's affected part, the orientation of the drainage scraper 460 is also different. When the plug post 410 and multiple cotton swabs 500 rotate simultaneously, the whole sample liquid extraction mechanism 400 does not need to worry;

[0104] Among them, the selection of the surface material of the plug post 410 needs to be selected according to the use requirements.

[0105] The working principle and usage process of the present invention: First, loosen the second bolt 130, then clamp the expanded chuck 110 and the pressure pad 140 at the central position of the tail end of the hospital bed, then tighten the second bolt 130, and then let the patient lie flat on the hospital bed. At this time, the chuck 110 faces the middle of the patient's legs;

[0106] Then, use tweezers to take out the plug pin 380. Next, insert the plug post 410 into the jack at the inner end of the linkage member 350. At this time, the limit inner ring 360 will clamp and press the plug post 410. Then, adjust the progressive screw 472 to rotate counterclockwise until the suspension 473 is delivered outward, and the position control plug heads 480 installed at both ends of the suspension 473 will extend outward along the outside of the anti-seepage pipe 471. At this time, the drainage scraping plate 460 is contracted toward the inner cavity of the liquid storage bin 420 under the action of the compression spring 450. At this time, the whole liquid storage bin 420 can be inserted into the inside of the plug post 410. Adjust the progressive screw 472 clockwise. At this time, the position control plug head 480 that contracts toward the inner cavity of the liquid storage bin 420 can extrude the drainage scraping plate 460 upward until the port at the top of the drainage scraping plate 460 penetrates to the outside of the plug post 410;

[0107] After the above-mentioned sample liquid extraction mechanism 400 is pre-installed, use tweezers to insert multiple cotton swabs 500 along the gap between the plug post 410 and the auxiliary sleeve 310 in sequence until the root of the cotton swab 500 is inserted into the inside of the thickening washer 372 and the gear shaft sleeve 343. At this time, the multiple cotton swabs 500 distributed in a circular pattern can be located outside the plug post 410. According to the distance between the cotton swab 500 and the plug post 410, the above-mentioned progressive screw 472 can be adjusted appropriately until the arc-shaped port at the top of the drainage scraping plate 460 contacts the cotton head of the cotton swab 500. Each time the progressive screw 472 is adjusted, the plug pin 380 needs to be inserted into the linkage member 350 until the plug pin 380 fixes the plug post 410. After the adjustment of the progressive screw 472 is completed, the plug pin 380 can be taken out again;

[0108] Then, place the pre-installed sampling assisting mechanism 300, sample liquid extraction mechanism 400, and multiple cotton swabs 500 in a sterilized environment for disinfection. When it is necessary to take samples from a patient, medical staff can take out the above components and install the auxiliary sleeve 310 at the threaded port of the main sleeve 220. At this time, the transmission shaft in the motor 240 can be docked with the other end of the linkage member 350. Then, insert the ranging beam rod 210 into the rectangular hole at the top of the beam arm 180;

[0109] During use, initially tighten the third bolt 190, then loosen the first bolt 120, and then control the beam arm 180 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 to make the beam arm 180 provide a stable support platform for the ranging beam rod 210. Then, loosen the third bolt 190, and then slowly horizontally move the ranging beam rod 210. According to the medical sampling regulations, when the horizontal movement dimension of the ranging beam rod 210 meets the requirements, the third bolt 190 can be tightened;

[0110] Then, press the switch 250 and start the motor 240;

[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. At this time, the multiple gear shaft sleeves 343 evenly distributed on the circumference can be linked at a uniform speed, which in turn drives the multiple evenly distributed cotton swabs 500 to rotate slowly (this process is used for patients with less fluid accumulation in the affected area). As 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 this location is continuously squeezed and scraped by the top of the drainage scraper 460 while rotating, and the entrained sample can be uniformly retained in the sealed space formed by the liquid storage tank 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 multiple 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. 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 sample material, and conduct multiple measurements in batches to ensure the accuracy of the measured 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 invention, and that the scope of the invention is defined by the claims and their equivalents.
