Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a vaginal secretion sampling device used in gynecological clinics. Background Art

[0002] In the process of clinical diagnosis and treatment of gynecology, vaginal secretion examination is an extremely routine and critical test item, which plays a pivotal role in the diagnosis, disease monitoring and treatment effect evaluation of various gynecological diseases such as vaginitis, cervicitis, pelvic inflammatory disease, etc. Its test results can accurately reveal important information such as the status of the vaginal microecological environment, the type of pathogen infection (such as bacteria, fungi, Trichomonas, etc.) and the degree of inflammation, laying a solid foundation for the formulation of subsequent targeted treatment plans.

[0003] However, the traditional method of vaginal secretion sampling mostly relies on manual sampling with medical cotton swabs. On the one hand, the sampling range of cotton swabs is narrow, and the internal structure of the vagina is complex, with many wrinkles, crypts and dome areas at different angles. It is difficult for cotton swabs to reach all key positions, resulting in incomplete samples, greatly reducing the reliability of the test results and increasing the probability of misdiagnosis of diseases. On the other hand, the rigidity of cotton swabs makes it very easy to scratch the vaginal mucosa during the insertion and rotation sampling process, causing obvious tingling and foreign body sensation to patients, aggravating the pain of patients, and easily causing medical-induced infections and prolonging the patient's recovery period. On the other hand, the subsequent sample transfer process of traditional cotton swab sampling is cumbersome and difficult. During the transfer from cotton swabs to glass slides and collection tubes, samples are prone to residue and spillage, which can easily cause sample loss. It is also easy to interfere with the accuracy of test data due to cross contamination, giving rise to false positives, false negatives and other adverse results. The operation is cumbersome and time-consuming, especially when facing a large number of patients to be tested, which seriously affects the work efficiency of the department, prolongs the waiting time of patients, and easily causes anxiety for both doctors and patients, which is not conducive to the improvement of the overall quality of medical services.

[0016] The beneficial effects of the present invention are: 1. Accurate sampling: The relative height of the four individual samplers can be adjusted through grooves and sliders, and sampling can be performed at different depths and positions in the vagina to avoid missing key areas. The sampling airbag can accurately change its volume under the control of the air pressure push rod, closely fitting the complex physiological curve of the inner wall of the vagina. The sampling airbag can be flexibly shifted to the surroundings through the adjustment mechanism, and can dynamically adjust its position according to the actual shape of the vagina, covering all areas of the inner wall of the vagina to the greatest extent, ensuring that representative secretion samples are collected, and providing strong support for accurate diagnosis.

[0017] 2. Convenient operation: Multiple individual samplers are connected by sliding. Medical staff can quickly adjust the overall length and angle according to the patient's vaginal depth and the location of the suspected lesion area, just like operating a telescopic tool. Depth positioning can be completed with one hand. The operation is flexible and smooth, and there is no need for cumbersome component assembly or angle calibration.

The spiral blades on the spiral shaft interact with the bottom connecting rod of the hydraulic rod, so that the hydraulic rod can be smoothly extended and retracted with the cooperation of the hydraulic cylinder. At the same time, the rotating rod is pulled by the telescopic rod to achieve offset, and each sampling airbag moves synchronously to avoid the tedious operation of each operation, ensuring the tight rhythm of the entire sampling process. For medical staff, they can quickly become familiar with the operating procedures and master the usage skills without undergoing lengthy and complicated training. Compared with traditional multi-instrument, multi-step combination sampling tools, the new device avoids tedious step-by-step operations and instrument assembly and debugging, lowers the operating threshold and error probability, and allows medical staff to focus more on the patients themselves and the control of sampling accuracy, thereby optimizing clinical workflows.

[0018] 3. High comfort: The soft protrusions on the surface of the sampling airbag are made of soft medical silicone material, which is skin-friendly and elastic. When it touches the vaginal mucosa, it fits gently like a massage, minimizing the scratching sensation. Compared with traditional hard plastic sampling instruments, it greatly reduces the patient's foreign body sensation and pain, allowing the patient to cooperate with the sampling in a relaxed state, reducing the interference of muscle contraction caused by tension on the sampling.

[0019] 4. Sample preservation is intact: The overall sealing of the device is good, which prevents the sample from being contaminated by the outside world during the collection and transfer process. The sample quality is protected from the sampling source to the end point of delivery, ensuring that the sample received by the laboratory is highly consistent with the original state in the vagina, laying a solid quality foundation for the subsequent complex inspection process.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] The inventors have found that the traditional method of vaginal secretion sampling can generally only take samples at the same height of the vagina through a sampling device, and requires manual operation of the sampling device, which takes more time to take more samples. In addition, the subsequent sample transfer process of the traditional sampling method is cumbersome and difficult, and samples are prone to residue and spillage, which can easily cause sample loss.

[0024] Based on the above findings, the present application proposes a vaginal secretion sampling device for gynecological clinical use, which takes samples from different points in the vagina by setting up 4 separate samplers. The 4 separate samplers adjust the relative heights through grooves and sliders, and can sample different depths and positions in the vagina to avoid missing key parts. The sampling airbag fits the inner wall of the vagina under the action of air pressure, and is driven to shift to the surroundings by a rotating component, which can cover all areas of the inner wall of the vagina to the greatest extent, ensuring that representative secretion samples are collected, providing strong support for accurate diagnosis, and all adjustment functions are integrated in the key operation point of the rotating rod. Without going through lengthy and complicated training, you can quickly become familiar with the operation process and master the usage skills. Embodiment 1

Each individual sampler comprises a protective shell 3, a sampling mechanism 4 and an adjusting mechanism 5. A protective shell 3 is provided in the middle and lower part of each individual sampler. A groove 301 and a slider 302 are provided on both sides of the protective shell 3. Each adjacent individual sampler is connected by sliding up and down through the groove 301 and the slider 302, respectively, to adjust the relative height of each sampler, so as to deliver each sampler to the most suitable and most valuable sampling depth position in the vagina, thereby ensuring that secretions are collected from different levels and angles, and effectively improving the comprehensiveness of sampling.

[0026] Please check Figure 5 , Figure 7 , Figure 8 , Fig. 9 The sampling mechanism 4 passes through the protective shell 3 and is used to collect vaginal secretion samples. It includes a sampling airbag 401, a rotating rod 402 and a manual operating part. The rotating rod 402 passes through the protective shell 3 and is vertically connected to the manual operating part upward to transmit rotation and air pressure power. The top of the rotating rod 402 is connected to the sampling airbag 401 and extends into the interior of the sampling airbag 401. The sampling airbag 401 is used to fit the inner wall of the vagina to collect secretion samples. Specifically, the airbag 401 is tightly sleeved on the top of the rotating rod 402, and the airbag 401 is airtight to ensure that the gas channel for the expansion and contraction of the airbag 401 can only be achieved through the rotating rod 402. The material of the airbag 401 is medical silicone, which has good biocompatibility, is non-irritating to the human body, and has a soft texture and durability. The surface of the airbag 401 is provided with soft protrusions 406, to increase the fit and comfort, a small hole 405 is provided at one end of the rotating rod 402 extending into the sampling airbag 401, the manual operation part includes an air cavity 403 and a pneumatic push rod 404, the air cavity 403 is fixedly connected to the bottom of the rotating rod 402, and the air cavity 403 and the rotating rod 402 are both hollow structures, the air cavity 403 is used to store and transfer gas, control the expansion and contraction of the sampling airbag 401, and adjust its size, the air cavity 403 is penetrated and slidably connected with a pneumatic push rod 404, which is used to adjust the air pressure in the air cavity 403, thereby controlling the expansion degree of the sampling airbag 401, when the pneumatic push rod 404 is pushed upward, the gas in the air cavity 403 enters the sampling airbag 401 through the rotating rod 402, so that the sampling airbag 401 is enlarged and fits the inner wall of the vagina, and when the pneumatic push rod 404 is pulled downward, the sampling airbag 401 contracts.

[0027] Please check Figure 10-Figure 14The adjustment mechanism 5 is used to adjust the position and angle of the sampling airbag 401, and includes a support rod 501, a pushing portion, a hydraulic cylinder 503 and a telescopic rod 504. The support rod 501 is fixedly arranged inside the protective shell 3 to provide support for the entire adjustment mechanism 5. The hydraulic cylinder 503 is fixedly installed on the support rod 501. The interior of the hydraulic cylinder 503 is a cavity structure and contains liquid to provide hydraulic power. The telescopic rod 504 is connected to the top of the hydraulic cylinder 503. The interior of the telescopic rod 504 is a cavity structure for receiving the hydraulic power from the hydraulic cylinder 503 to cause the telescopic rod 504 to extend and retract. The telescopic rod 504 is connected to the rotating rod 402 through the clamp 505 at its front end to adjust the rotating rod 40 2, a pushing part is connected to the bottom of the hydraulic cylinder 503, and the pushing part includes a telescopic hydraulic rod 502 and a connecting rod 506. The hydraulic rod 502 is connected to the bottom of the hydraulic cylinder 503, and a connecting rod 506 is fixedly connected to the bottom of the hydraulic rod 502. A sliding groove 5011 is provided on the support rod 501, and one end of the connecting rod 506 slides up and down in the sliding groove 5011, and the other end is connected to a transmission mechanism 6. The transmission mechanism rotates and drives the connecting rod 506 to move upward. The connecting rod 506 drives the hydraulic rod to shrink upward, pushing the liquid in the hydraulic cylinder 503 into the telescopic rod 504, and then pushing the telescopic rod 504 to extend, so that the chuck 505 pushes the rotating rod 402 to deflect.

[0028] The transmission mechanism 6 includes a driving gear 601 and a driven member, and the driven member includes a driven gear 602 and a spiral shaft 605. The driving gear 601 is sleeved on the middle part of the rotating rod 402 to transmit the rotational power of the rotating rod 402. A support platform 603 is fixed on the support rod 501, and a first rotating shaft 604 is rotatably provided on the support platform 603. The support platform 603 is used to support the first rotating shaft 604 and ensure its smooth rotation. The driven gear 602 is sleeved on the first rotating shaft 604 and meshes with the driving gear 601. The driven gear 602 The power of the wheel 601 is transmitted to the first rotating shaft 604, and a second rotating shaft 6051 is fixedly connected above the first rotating shaft 604. A spiral shaft 605 is sleeved on the second rotating shaft 6051. The spiral shaft 605 includes a second rotating shaft 6051 and a spiral blade 6052. The spiral blade 6052 is sleeved on the second rotating shaft 6051 from top to bottom. The end of the connecting rod 506 away from the sliding groove 5011 extends between the spiral blades 6052. The rotation of the spiral shaft 605 will drive the connecting rod 506 to slide up and down along the spiral blade 6052, thereby driving the hydraulic rod 502 to extend and retract up and down. When the rotating rod 402 is rotated, the rotating rod 402 drives the driving gear 601 to rotate, and the driving gear 601 drives the driven gear 602 to rotate. At the same time, the driven gear 602 drives the spiral shaft 605 to rotate. The rotation of the spiral shaft 605 drives the connecting rod 506 to slide upward along the spiral blade 6052 and drives the hydraulic rod 502 to shrink upward, thereby driving the rotating rod 402 to deviate, so that the sampling airbag 401 deviates to the surroundings and fits the inner wall of the vagina.

[0029] Furthermore, the rotating assembly 6 also includes a large gear 606, which is fixedly mounted on the bottom of the protective tube 1 and fixedly connected to the protective shell 3 of one of the individual samplers. The large gear 606 is meshedly connected with the driving gears 601 of the four individual samplers, and is used to transmit the rotational power of an individual sampler to the entire device, thereby ensuring the synchronous transmission of the rotational power.

[0030] Furthermore, two openings of different shapes are provided at the bottom of the protection tube 1 , and the upper ends of the support rod 501 and the adjustment mechanism 5 are arranged to pass through the openings, so as to facilitate observation of the angle adjustment of the rotating rod 402 by the adjustment mechanism 5 .

[0031] Furthermore, a hard protrusion 408 is provided on the air cavity 403 to increase friction. When the rotating rod 402 is rotated, the rotating rod 402 can be driven to rotate by holding the air cavity 403. The shape of the hard protrusion 408 can be circular, diamond or other geometric shapes to increase the comfort and stability of holding.

[0032] Furthermore, the rotating rod 402 above the driving gear 601 is made of soft material, and the outer surface of the soft part is provided with a smooth coating to reduce friction with the inner wall of the vagina and improve the comfort of the patient.

[0033] When in use, first, according to the actual situation of the patient's vagina and the specific requirements of sampling, the relative heights of the individual samplers are adjusted through the grooves 301 and the sliders 302 on both sides of the protective shell 3, and then the sampling device with adjusted height is slowly inserted into the vagina. After insertion, the air pressure push rod 404 in the individual sampler is pushed. At this time, the gas enters the sampling airbag 401 from the air cavity 403 through the rotating rod 402, so that the sampling airbag 401 is enlarged. At the same time, the expansion of the sampling airbag 401 is observed to ensure that it can fit the inner wall of the vagina, but does not expand excessively to cause pressure on the vagina. Next, the rotating rod 402 is rotated, and the driving gear 601 in the middle of the rotating rod 402 rotates accordingly, driving the driven gear 602 meshing therewith, as well as the first rotating shaft 604 and the spiral shaft 605 to rotate. The rotation of the spiral shaft 605 causes the hydraulic rod 502 to move upward through the connecting rod 506 in the adjusting mechanism 5. The upward movement of the hydraulic rod 502 pushes the liquid in the hydraulic cylinder 503 to flow into the telescopic rod 504, thereby pushing the telescopic rod 504 to extend, so as to push the rotating rod 402 to deflect through the telescopic rod 504 and the clamp 505. At this time, the sampling airbag 401 will deflect to the surroundings to better fit various parts of the inner wall of the vagina to ensure comprehensive fit. Since the large gear 606 is meshed and connected with the driving gears 601 of the four separate samplers, rotating the rotating rod 402 of a separate sampler can make the sampling airbag 401 of the entire device synchronously perform the offset fitting operation. After the sampling is completed, the device is slowly removed from the vagina in the opposite order to the insertion.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
