Description

Technical Field

[0001] The present invention relates to the technical field of sampling and detection of gynecological secretions, and specifically provides a sampling and detection device for gynecological secretions. Background Art

[0002] Sampling and detection of gynecological secretions is an important means to evaluate the health status of the female reproductive system and is crucial for detecting inflammation, infections, changes in hormone levels, and other gynecological problems. Vaginal secretions, commonly known as "leukorrhea", are mainly composed of secretions from the cervical glands, Bartholin's glands, endometrium, and vaginal mucosa, and contain bacteria, white blood cells, exfoliated cells of the cervix and vaginal mucosa, etc. By sampling vaginal secretions, early detection of bacterial infections, Candida infections, and sexually transmitted diseases (STDs) can be achieved, which is crucial for timely treatment and prevention of disease transmission.

[0003] The existing Chinese patent with the publication number CN117958867A includes a substrate and a sampling tube. A through hole is provided at the top of the substrate, and the outer surface of the sampling tube is slidably connected to the inner surface of the through hole. A top cover is provided on the upper end surface of the sampling tube, a round head is provided on the lower end surface of the sampling tube, and a plurality of sampling holes are evenly provided on the outer surface of the sampling tube near the lower end surface; a sampling assembly, the sampling assembly is fixedly connected to the inner surface of the sampling tube, and the sampling assembly includes a fixing plate, and a first motor is fixedly connected to the top of the fixing plate.

[0004] When the above device is in use, four sampling swabs can be sent out inside the vagina through the drive of the first motor to complete multi-point sampling of secretions, improving the richness of the detection samples. At the same time, it is not necessary to push the sampling tube multiple times for sampling, reducing the discomfort of the patient during the sampling and detection process. However, in the actual use process, the vaginal wall is in a natural contraction state without support. When the sampling swab samples the vaginal secretions, it is easy to cause damage to the vaginal wall mucosa, increasing the pain of the patient and the risk of vaginal infection. Therefore, it is difficult to automatically support the patient's vaginal wall during sampling.

[0005] Therefore, we propose a sampling and detection device for gynecological secretions. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] First, by providing an airbag on the sampling tube, it can automatically support the inner wall of the vagina when inserted into the vagina of a patient, effectively avoiding mucosal damage caused by the natural contraction of the inner wall of the vagina, thereby reducing the discomfort and pain of the patient during the sampling process. The inflation of the airbag provides a stable operation environment for sampling, reduces the risk of damage and infection to the vagina, and improves the safety of the sampling process.

[0018] Second, by providing a sampling mechanism on the threaded sleeve rod, including a moving plate, a fixed rod, and a connecting sleeve, multi-point sampling of vaginal secretions can be achieved, improving the representativeness of the sample.

[0019] Third, through the provided sealing mechanism, the hole grooves on the rotating plate are sealed by the sealing plate, ensuring the stability of the sample in the sampling tube, avoiding the risk of the sample being contaminated by external air or cross-contaminated, making the entire sampling process simpler and more hygienic, thereby improving the purity of the test sample and the accuracy of the test results.

[0020] Fourth, through the provided liquid storage tank and liquid discharge mechanism, used to mix physiological saline with the secretion sample. Since the osmotic pressure of physiological saline is similar to that of human cells, it can maintain the activity of cells in the sample, which is particularly important for test items sensitive to cell activity. The design of the liquid discharge mechanism enables the physiological saline to be fully mixed with the sample on the sampling swab, avoiding drying and degradation of the sample, thus ensuring the accuracy and reliability of the test results.

[0021] By using the cooperation of the above structures, the problem that in the actual use process of the existing device, the vaginal inner wall is in a natural contraction state without support.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0034] Example 1, please refer to Figures 1 to 10, the present invention provides a technical solution: a sampling and detection device for gynecological secretions, including a sampling tube 1 inserted into the vagina of a patient. A cylindrical block 2 is horizontally movably connected to the inner wall at one end of the sampling tube 1. A threaded sleeve rod 3 penetrates through the inner wall of the cylindrical block 2 and is rotatably connected, and the sampling tube 1 is penetrated by the threaded sleeve rod 3 and movably connected. An airbag 4 for supporting the inner wall of the vagina is fixedly connected to the outer contour of the end of the sampling tube 1 away from the cylindrical block 2. A ventilation hole 101 for inflating the inside of the airbag 4 is provided on the sampling tube 1. A cavity 201 is provided on the cylindrical block 2. A locking block 5 for locking the threaded sleeve rod 3 is movably connected to the inner wall of the cavity 201. A locking groove 301 is provided on the outer contour of the threaded sleeve rod 3 at the position corresponding to the locking block 5. A first spring 6 for guiding the reset movement of the locking block 5 is fixedly connected to the opposite surface of the locking block 5 and the cavity 201. One end of the sampling tube 1 close to the cylindrical block 2 is penetrated and rotatably connected by a threaded rod 9 driven by a power mechanism, and the threaded rod 9 penetrates into the inner wall of the threaded sleeve rod 3 and is screwed;

[0035] A sampling mechanism for sampling vaginal secretions is provided on the threaded sleeve rod 3. A connecting sleeve 12 and a circular plate 13 are provided on the sampling mechanism. A sampling swab is inserted and fixed on the connecting sleeve 12. A support rod 23 for adjusting the sampling angle of the connecting sleeve 12 is fixedly connected to the circular plate 13.

[0036] During use, by providing the sampling tube 1 and the cylindrical block 2 provided on the sampling tube 1, the cylindrical block 2 can be horizontally movably connected to the inner wall of the sampling tube 1. Through the threaded sleeve rod 3 provided on the cylindrical block 2, the threaded sleeve rod 3 is rotatably connected to the inner wall of the cylindrical block 2. Through the cavity 201 provided on the cylindrical block 2 and the locking block 5 provided on the cavity 201, the cavity 201 can limit and support the moving direction of the locking block 5. Through the first spring 6 provided on the locking block 5 and the locking groove 301 provided on the threaded sleeve rod 3, the locking block 5 can move to the inner wall of the locking groove 301 for engagement under the elastic force of the first spring 6, realizing the locking of the threaded sleeve rod 3. Through the threaded rod 9 provided on the sampling tube 1 and the threaded rod 9 driven by a motor to rotate, the motor can drive the threaded rod 9 to rotate axially and reciprocally on the sampling tube 1, and the threaded rod 9 is screwed to the inner wall of the threaded sleeve rod 3. Along with the axial and reciprocating rotation of the threaded rod 9, the threaded sleeve rod 3 can drive the cylindrical block 2 to horizontally reciprocate on the inner wall of the sampling tube 1 under the action of the threaded rod 9.

[0037] Through the airbag 4 provided on the sampling tube 1 and the ventilation holes 101 opened on the sampling tube 1, the ventilation holes 101 can connect the sampling tube 1 with the inner wall of the airbag 4. When sampling the vaginal secretions of a patient, first insert the end of the sampling tube 1 close to the airbag 4 into the vagina. At this time, the threaded rod 9 drives the cylindrical block 2 to move horizontally towards the airbag 4 through the threaded sleeve rod 3, and the internal air pressure at the end of the sampling tube 1 close to the airbag 4 is positive pressure. Then the cylindrical block 2 can fill the gas inside the sampling tube 1 into the inner wall of the airbag 4 through the ventilation holes 101, so that the airbag 4 expands and supports the inner wall of the vagina, avoiding the problem that the inner wall of the vagina naturally contracts during subsequent sampling of vaginal secretions, resulting in damage to the vaginal mucosal membrane, and improving the comfort and safety of sampling.

[0038] When the cylindrical block 2 moves horizontally and resets towards the direction away from the airbag 4, the above structure synchronously moves in the opposite direction for resetting, so as to facilitate the subsequent removal of the sampled sampling tube 1 from the patient's vagina.

[0039] Embodiment 2, on the basis of Embodiment 1, further:

[0040] The sampling mechanism includes that one end of the threaded sleeve rod 3 far from the cylindrical block 2 is horizontally movably connected with a moving plate 10, and a fixed rod 11 is fixedly connected to the moving plate 10. A connecting sleeve 12 is rotatably supported at one end of the fixed rod 11 far from the moving plate 10. A circular plate 13 is fixedly connected to the outer contour of the threaded sleeve rod 3 close to the moving plate 10. A second spring 14 for guiding the reset movement of the moving plate 10 is fixedly connected to the opposite surfaces of the circular plate 13 and the moving plate 10.

[0041] The moving plate 10 is penetrated by the circular plate 13 and horizontally movably connected. One end of the support rod 23 is fixedly connected with a connecting rod 22 for supporting the connecting sleeve 12, and the other end of the connecting rod 22 far from the support rod 23 is fixedly connected with the connecting sleeve 12.

[0042] During use, through the moving plate 10 provided on the threaded sleeve rod 3, and the moving plate 10 is axially movably sleeved on the outer contour of the threaded sleeve rod 3, then the moving plate 10 is attached to and movably connected with the inner wall of the sampling tube 1. Through the circular plate 13 provided on the threaded sleeve rod 3, the circular plate 13 is fixedly supported on the threaded sleeve rod 3, and the second spring 14 provided on the circular plate 13 can support the position of the moving plate 10 by the second spring 14.

[0043] Through the fixed rod 11 provided on the moving plate 10, the fixed rod 11 is fixedly supported on the moving plate 10, and a connecting sleeve 12 is provided on the fixed rod 11, so that the connecting sleeve 12 is rotatably connected to the fixed rod 11 about a fixed axis. First, the medical staff fixes the sampling swab on the inner wall of the connecting sleeve 12. Through the support rod 23 provided on the circular plate 13 and the connecting rod 22 provided on the support rod 23, the connecting rod 22 can support the angle of the connecting sleeve 12 under the action of the support rod 23.

[0044] When the threaded sleeve rod 3 drives the cylindrical block 2 to move towards the airbag 4, and the second spring 14 supports the moving plate 10, the threaded sleeve rod 3 can push the sampling swab on the connecting sleeve 12 to move into the patient's vagina. When the moving plate 10 moves to the limit position at the end of the sampling tube 1 away from the threaded rod 9, and the sampling tube 1 supports the moving plate 10, at this time, the circular plate 13 can drive the support rod 23 to move towards the connecting sleeve 12 under the push of the threaded sleeve rod 3, and the second spring 14 is squeezed and contracted under the action of the circular plate 13. Thus, the connecting rod 22 can push the connecting sleeve 12 to rotate 45° in the vertical direction under the action of the support rod 23, and the sampling swab on the connecting sleeve 12 can be rotated to contact the inner wall of the vagina and sample the secretions.

[0045] When the threaded sleeve rod 3 drives the cylindrical block 2 to move back towards the direction away from the airbag 4, the above structure moves back synchronously in the opposite direction, and the sampling swab after sampling on the connecting sleeve 12 can be moved into the sampling tube 1.

[0046] Embodiment 3, on the basis of Embodiment 2, further:

[0047] An unlocking mechanism for unlocking the threaded sleeve rod 3 is provided on the cylindrical block 2. The unlocking mechanism includes a moving rod 7 that penetrates through and is horizontally movably connected to the side of the cylindrical block 2 close to the cavity 201 and communicates with the inner wall of the cavity 201. A slider 8 is fixedly connected to the side of the locking block 5 close to the moving rod 7, and a V-shaped groove 701 for movably supporting the slider 8 is provided on the moving rod 7.

[0048] During use, through the moving rod 7 provided on the cylindrical block 2, the moving rod 7 can be horizontally movably connected to the cylindrical block 2. Through the slider 8 provided on the locking block 5, the slider 8 is fixedly supported on the locking block 5, and a V-shaped groove 701 is formed on the moving rod 7. Then, the V-shaped groove 701 can movably support the slider 8. When the threaded rod 9 rotates clockwise and drives the threaded rod 9 to move towards one end close to the airbag to the limit position, at this time, the moving rod abuts against the inner wall of the sampling tube, so that the cylindrical block can drive the slider to move towards one end of the V-shaped groove. And under the action of the V-shaped groove, the slider pulls the locking block to move in the vertical direction away from the threaded sleeve rod, enabling the first spring to be squeezed and contracted under the action of the locking block. At the same time, the locking block is disengaged from the locking groove and unlocks the threaded sleeve rod. Thus, the threaded rod 9 drives the threaded sleeve rod to rotate synchronously. When the threaded rod 9 rotates counterclockwise, at this time, the locking block moves back to the inner wall of the locking groove under the elastic force of the first spring, and the locking block locks the threaded sleeve rod, enabling the threaded sleeve rod to drive the cylindrical block to move back towards the end away from the airbag.

[0049] As the circular plate 13 moves towards the direction close to the moving plate 10, at this time, the cylindrical block 2 drives the moving rod 7 to abut against and move along the inner wall of one end of the sampling tube 1, and the cylindrical block 2 can drive the slider 8 to move towards the end of the V-shaped groove 701, so that the slider 8 can pull the locking block 5 to move towards the direction close to the first spring 6 under the action of the V-shaped groove 701. And the first spring 6 is squeezed and contracted under the action of the locking block 5. At the same time, the locking block 5 moves and is disengaged from the locking groove 301, then the locking block 5 unlocks the threaded sleeve rod 3, enabling the threaded sleeve rod 3 to rotate synchronously with the threaded rod 9. Thus, the connecting sleeve 12 can drive the sampling swab to perform multi-point sampling on the vaginal wall secretion, improving the richness of the detection sample and the accuracy of the detection result.

Through the inclined slot 103 opened on the sampling tube 1, and the movable block 19 is movably supported on the inner wall of the inclined slot 103. When the circular plate 13 moves to the limit position near one end of the third spring 21 of the sampling tube 1, and the sampling swab on the connecting sleeve 12 moves into the sampling tube 1.

[0059] As Figure 1 , Figure 5 , Figure 6 , Figure 9 and Figure 10 shown, when the sealing plate 17 releases the seal on the hole groove of the rotating plate 16, and the liquid inlet hole 241 opened on the connecting tube 24, at this time, the liquid inlet hole 241 deviates from the end of the liquid inlet tube 26, so that the outer wall of the connecting tube 24 fits with the end of the liquid inlet tube 26 for sealing. Along with the circular plate 13 pushing the slide bar 20 to move towards the direction close to the third spring 21 to the limit position, and the sealing plate 17 seals the hole groove of the rotating plate 16. At the same time, the liquid inlet hole 241 moves to the corresponding position of the end of the liquid inlet tube 26 under the push of the slide bar 20, then the liquid inlet hole 241 connects the connecting tube 24 with the liquid inlet tube 26. Thus, the liquid inlet tube 26 can discharge the physiological saline inside the liquid storage tank 27 through the connecting tube 24 and the through hole 211 to the inner wall of the sampling tube 1 near one end of the connecting sleeve 12. By the medical staff placing one end of the air bag 4 in the downward vertical direction, the physiological saline can contact and fuse with the sample on the sampling swab. At the same time, the cylindrical block 2 moves to the limit position away from one end of the air bag 4, and the locking block 5 releases the lock on the threaded sleeve rod 3, enabling the connecting sleeve 12 to drive the sampling swab to rotate in the solution, improving the mixing effect of the solution and the sample. The osmotic pressure of the physiological saline is similar to that of human cells, which can maintain the activity of the cells and ensure the accuracy of the test results.

[0060] Furthermore, it is realized that the existing device can automatically support the inner wall of the patient's vagina during actual use, which is convenient to use and better than traditional products.

[0061] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be directly processed without any doubt according to the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0062] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
