Description

Technical Field

[0001] The present 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] Vaginal discharge examination is a routine and critical test in gynecological clinical diagnosis and treatment. It plays a crucial role in the diagnosis, monitoring, and treatment efficacy evaluation of various gynecological conditions, including vaginitis, cervicitis, and pelvic inflammatory disease. Its results can accurately reveal important information such as the vaginal microecological environment, the type of pathogen infection (such as bacteria, fungi, and Trichomonas), and the degree of inflammation, laying a solid foundation for the development of subsequent targeted treatment plans.

[0003] However, traditional vaginal secretion sampling methods often rely on manual sampling with medical cotton swabs. On the one hand, the cotton swab sampling range is narrow, and the vaginal internal structure is complex, with numerous folds, crypts, and domes at different angles. It is difficult for the cotton swab to reach all key locations, resulting in incomplete samples, greatly reducing the reliability of test results and increasing the probability of misdiagnosis of diseases. On the other hand, the rigid nature of the cotton swab makes it very easy to scratch the vaginal mucosa during insertion and rotation, causing patients to experience significant stinging and foreign body sensations, exacerbating their pain, and easily causing nosocomial infections and prolonging their recovery period. Furthermore, traditional cotton swab sampling is cumbersome and difficult to transfer samples. During the transfer from the cotton swab to the glass slide or collection tube, the sample is easily left over or spilled, which can easily cause sample loss. Cross-contamination can also interfere with the accuracy of test data, resulting in false positives, false negatives, and other adverse results. The cumbersome and time-consuming operation, especially when faced with a large number of patients awaiting examination, seriously affects departmental efficiency, prolongs patient waiting times, and easily causes anxiety for both doctors and patients, hindering the overall quality of medical services. Summary of the Invention

[0004] In response to the above-mentioned problems, the present invention aims to provide a vaginal secretion sampling device for gynecological clinical use, which can not only meet the needs of multi-dimensional sampling and flexibly adjust the height and angle of the sampling site, but also facilitate the collection and preservation of samples, and can minimize discomfort and avoid damage.

[0005] The main idea of ​​the technical solution adopted by the present invention is: a protective tube with a partition plate is used to accommodate multiple separate samplers, which are slidably connected by grooves and sliders, which is convenient for storage and management, and can flexibly adjust the height of each sampling unit to adapt to different vaginal physiological structures, ensuring deep and multi-angle access to the sampling site; by setting up air pressure drive, the sampling airbag can be controllably expanded to fit the inner wall of the vagina, and the soft protrusion assists in close contact, enhances the effect of absorbing secretions, and accurately collects samples; by setting up a hydraulic rod and a telescopic rod, the rotating rod is offset under the drive of the rotating assembly, driving the sampling airbag to extend and fit around, and cooperate with the large gear to achieve power sharing. The units work together to achieve sampling at different sites.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0009] The sampling mechanism penetrates the protective shell and includes a manual operating portion, a rotating rod that penetrates the protective shell and is vertically connected to the manual operating portion, and a sampling airbag connected to the top of the rotating rod for sampling vaginal secretions. By pushing the manual operating portion upward, the sampling airbag expands and fits the inner wall of the vagina.

[0010] The adjusting mechanism is arranged on one side of the sampling mechanism and is connected to the sampling mechanism through a transmission mechanism so as to make the sampling airbag deviate to all sides and be used to make the sampling airbag fit the inner wall of the vagina for easy sampling.

[0012] Through the above technical solution, further: the transmission mechanism includes a driving gear and a driven member, the driving gear is sleeved on the middle part of the rotating rod, and the driven member is arranged on one side of the driving gear. By rotating the rotating rod, the driving gear is driven to rotate, and the driven member is also driven to rotate.

[0013] According to the above technical solution, further: the driven member includes a driven gear and a screw shaft, the driven gear is sleeved on the first rotating shaft and meshed with the driving gear, and the screw shaft is fixedly connected above the first rotating shaft.

[0014] According to the above technical solution, further: the spiral shaft includes a second rotating shaft and a spiral blade, and the spiral blade is sleeved on the second rotating shaft from top to bottom.

[0015] According to the above technical solution, further: the adjustment mechanism is arranged on one side of the transmission mechanism, which includes a pushing part, a hydraulic cylinder arranged above the pushing part, and a telescopic rod connected to the top of the hydraulic cylinder, the telescopic rod is connected to the rotating rod through a clamp at its front end, the interior of the hydraulic cylinder and the telescopic rod are both hollow structures, and the interior of the hydraulic cylinder contains liquid;

[0016] When the pushing portion moves upward, it pushes the liquid in the hydraulic cylinder into the telescopic rod, thereby pushing the telescopic rod to extend, so that the clamp pushes the rotating rod to deflect.

[0017] Through the above technical solution, further: the pushing part includes a retractable hydraulic rod and a connecting rod connected to the bottom of the hydraulic rod, the hydraulic rod is connected to the bottom of the hydraulic cylinder, and a support rod is fixedly provided on one side of the transmission mechanism. The hydraulic cylinder is fixedly provided on the support rod, and a sliding groove is provided on the support rod. One end of the connecting rod slides up and down in the sliding groove, and the other end extends between the spiral blades.

[0018] Through the above technical solution, further: a support platform is fixedly provided on the support rod, the support platform is located below the sliding groove, and the support platform is rotatably connected to the first rotating shaft for supporting the first rotating shaft.

[0019] Through the above technical solution, further: the rotating assembly also includes a large gear, which is arranged at the bottom of the protective tube and fixedly connected to the protective shell of one of the individual samplers.

[0020] Through the above technical solution, further: a soft protrusion is provided on the sampling airbag, and a hard protrusion is provided on the air cavity.

[0021] The beneficial effects of the present invention are:

[0022] 1. Precise Sampling: The four individual samplers can adjust their relative heights through grooves and sliders, enabling sampling at different depths and locations within the vagina to avoid missing key areas. Combined with the sampling airbag, the volume can be precisely changed under the control of the pneumatic push rod, closely fitting the complex physiological curves of the vaginal inner wall. The adjustment mechanism allows the sampling airbag to flexibly shift in all directions, dynamically adjusting its position according to the actual shape of the vagina. This allows for maximum coverage of all areas of the vaginal inner wall, ensuring the collection of representative secretion samples and providing strong support for accurate diagnosis.

[0023] 2. Convenient operation: Multiple individual samplers are connected by sliding connections. 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 tedious component assembly or angle calibration. This greatly shortens preoperative preparation time and significantly improves work efficiency in busy gynecological clinics or wards. The coordinated design of the adjustment mechanism and the sampling mechanism simplifies complex operations. Medical staff only need to turn the rotating rod of any individual sampler. The power is evenly distributed to all related components through the large gear. The driving gear and the driven gear in the middle of the rotating rod are tightly engaged, driving the spiral shaft to rotate. The spiral blades on the spiral shaft interact with the connecting rod at the bottom of the hydraulic rod, allowing the hydraulic rod to smoothly extend and retract with the cooperation of the hydraulic cylinder. At the same time, the rotating rod is pulled by the telescopic rod to achieve offset. The sampling airbags act synchronously, avoiding the tedious operation of each operation and ensuring a 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.

[0024] 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 contacts 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.

[0025] 4. Integrity of sample preservation: The device is well sealed as a whole, preventing the sample from being contaminated by the outside world during the collection and transfer process. The quality of the sample is protected from the sampling source to the end point of inspection, ensuring that the sample received by the laboratory is highly consistent with the original state in the vagina, laying a solid quality foundation for subsequent complex inspection processes.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0043] 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 the samples are prone to residue and spillage, which can easily cause sample loss.

[0044] 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 four separate samplers. The four separate samplers adjust the relative height through grooves and sliders, and can sample different depths and positions in the vagina to avoid missing key parts. Combined with the sampling airbag fitting the inner wall of the vagina under the action of air pressure, and driving it to shift to the surroundings through the rotating component, it 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. Example 1

[0045] See Figures 1-15The present application discloses a vaginal secretion sampling device for gynecological clinical use, comprising at least two separate samplers, preferably four separate samplers. A protective tube 1 is provided in the upper middle portion of the sampling device for protecting the sampling airbag 401. The protective tube 1 can be set to be transparent to facilitate observation of the internal sampling device. The protective tube 1 is divided into four parts by a partition plate 2, each part accommodating a separate sampler. The partition plate 2 is in the form of a thin sheet and is made of the same material as the protective tube 1. It can be fixed or detachable for easy cleaning and disinfection. Each individual sampler includes a protective shell 3, a sampling mechanism 4 and an adjustment mechanism 5. A protective shell 3 is provided in the middle and lower part of each individual sampler, and grooves 301 and sliders 302 are respectively provided on both sides of the protective shell 3. Each adjacent individual sampler is connected to each other by sliding up and down through the grooves 301 and sliders 302, which are matched with each other, so as to adjust the relative height of each sampler and 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.

[0046] Please check Figure 5 、 Figure 7 、 Figure 8 、 Figure 9The 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 for transmitting 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 sealed and 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, 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, and 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 for adjusting 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 increases and fits the inner wall of the vagina, and when the pneumatic push rod 404 is pulled downward, the sampling airbag 401 contracts.

[0047] Please check Figure 10-14The adjusting 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 fixed inside the protective shell 3 to provide support for the entire adjusting mechanism 5. A 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 for providing hydraulic power. A telescopic rod 504 is connected above 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 retractable 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 the transmission mechanism 6. When the transmission mechanism rotates, it drives the connecting rod 506 to move upward. The connecting rod 506 drives the hydraulic rod to retract 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.

[0048] The transmission mechanism 6 includes a driving gear 601 and a driven member, and the driven member includes a driven gear 602 and a screw 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. 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 retract upward, thereby driving the rotating rod 402 to deflect, so that the sampling airbag 401 deflects to the four sides and fits the inner wall of the vagina.

[0049] 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 meshed with the driving gears 601 of the four individual samplers to transmit the rotational power of an individual sampler to the entire device, thereby ensuring the synchronous transmission of the rotational power.

[0050] 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 upper ends of 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 .

[0051] 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.

[0052] 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.

[0053] 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 4 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. Then, 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, the first rotating shaft 604 and the screw shaft 605 that are meshed therewith to rotate. The rotation of the screw 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, thereby pushing 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 four sides to better fit various parts of the vaginal wall and 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 airbags 401 of the entire device perform the offset and fitting operation synchronously. After the sampling is completed, the device is slowly removed from the vagina in the reverse order of insertion.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
