Description

Technical Field

[0001] The invention relates to the technical field of sampling and detecting gynecological secretions, and in particular to a sampling and detecting device for gynecological secretions. Background Art

[0002] Gynecological secretion sampling and testing is an important means of evaluating the health of the female reproductive system. It is crucial for detecting inflammation, infection, changes in hormone levels and other gynecological problems. Vaginal secretions, commonly known as "leucorrhea", are mainly composed of secretions from cervical glands, Bartholin's glands, endometrium and vaginal mucosa. They contain bacteria, white blood cells, exfoliated cells of the cervix and vaginal mucosa, etc. Sampling of vaginal secretions can detect bacterial infections, Candida infections and sexually transmitted diseases (STDs) at an early stage, which is crucial for timely treatment and prevention of disease transmission.

[0003] The existing Chinese patent with publication number CN117958867A includes a base plate and a sampling tube, wherein a through hole is provided on the top of the base plate, 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, wherein 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 from the inside of the vagina through the drive of the first motor to complete multi-point secretion sampling, thereby improving the richness of the test samples. At the same time, there is no need to push the sampling tube multiple times for sampling, which reduces the patient's discomfort during the sampling and testing process. However, in actual use, the inner wall of the vagina is in a naturally contracted state without support. When the sampling swab samples the vaginal secretions, it is easy to cause damage to the inner wall mucosa of the vagina, increasing the patient's pain and the risk of vaginal infection. Therefore, it is difficult to automatically support the inner wall of the patient's vagina during sampling.

[0005] For this reason, we propose a sampling and detection device for gynecological secretions. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The airbag set on the sampling tube can automatically support the inner wall of the vagina when inserted into the patient's vagina, effectively avoiding mucosal damage caused by natural contraction of the inner wall of the vagina, thereby reducing the patient's discomfort and pain during the sampling process. The expansion of the airbag provides a stable operating environment for sampling, reduces the risk of damage and infection to the vagina, and improves the safety of the sampling process.

[0017] 3. Through the sealing mechanism, the holes and grooves on the rotating plate are sealed by the sealing plate, which ensures the stability of the sample in the sampling tube and avoids the risk of sample contamination or cross contamination by external air, making the entire sampling process simpler and more hygienic, thereby improving the purity of the test sample and the accuracy of the test results.

[0018] 4. The liquid storage tank and drainage mechanism are used to mix physiological saline with secretion samples. Since the osmotic pressure of physiological saline is similar to that of human cells, the activity of cells in the sample can be maintained, which is particularly important for detection items that are sensitive to cell activity. The design of the drainage mechanism enables the physiological saline to be fully mixed with the sample on the sampling swab, avoiding drying and degradation of the sample, thereby ensuring the accuracy and reliability of the test results.

[0019] The coordinated use of the above-mentioned structure solves the problem that, during actual use of the existing device, the inner wall of the vagina is in a naturally contracted state without support. When the sampling swab is used to sample vaginal secretions, it is easy to cause damage to the vaginal wall mucosa, increasing the patient's pain and the risk of vaginal infection. Therefore, it is difficult to automatically support the patient's vaginal wall during sampling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] For example, see Figures 1 to 10 The present invention provides a technical solution: a sampling and detection device for gynecological secretions, comprising a sampling tube 1 inserted into the patient's vagina, the inner wall of one end of the sampling tube 1 being horizontally movably connected to a cylindrical block 2, penetrating the inner wall of the cylindrical block 2 and being rotatably connected to a threaded sleeve 3, and the sampling tube 1 is penetrated by the threaded sleeve 3 and movably connected, the outer contour of the end of the sampling tube 1 away from the cylindrical block 2 is fixedly connected to an air bag 4 for supporting the inner wall of the vagina, the sampling tube 1 is provided with a vent 101 for inflating the inside of the air bag 4, the cylindrical The block 2 is provided with a cavity 201, and a locking block 5 for locking the threaded sleeve 3 is movably connected to the inner wall of the cavity 201, and a locking groove 301 is provided on the outer contour of the threaded sleeve 3 at the position corresponding to the locking block 5, and a first spring 6 for guiding the locking block 5 to return and move is fixedly connected to the opposite surface of the locking block 5 and the cavity 201, and the end of the sampling tube 1 close to the cylindrical block 2 is penetrated and connected to a threaded rod 9 driven to rotate by a power mechanism, and the threaded rod 9 penetrates the inner wall of the threaded sleeve 3 and is screwed; The threaded sleeve 3 is provided with a sampling mechanism for sampling vaginal secretions, the sampling mechanism is provided with a connecting sleeve 12 and a circular plate 13, and a sampling swab is inserted and fixed on the connecting sleeve 12, and a support rod 23 for adjusting the sampling angle of the connecting sleeve 12 is fixedly connected to the circular plate 13.

[0024] When in use, by setting the sampling tube 1 and the columnar block 2 arranged on the sampling tube 1, the columnar block 2 can be horizontally moved and connected to the inner wall of the sampling tube 1, and the threaded sleeve 3 arranged on the columnar block 2 is connected to the inner wall of the columnar block 2 for fixed-axis rotation. By the cavity 201 opened on the columnar block 2 and the locking block 5 arranged on the cavity 201, the cavity 201 can limit the moving direction of the locking block 5. By the first spring 6 arranged on the locking block 5 and the locking groove 301 opened on the threaded sleeve 3 , so that 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, thereby locking the threaded sleeve 3. Through the threaded rod 9 set on the sampling tube 1, and the threaded rod 9 is driven to rotate by the motor, so that the motor can drive the threaded rod 9 to perform fixed-axis reciprocating rotation on the sampling tube 1, and the threaded rod 9 is threadedly connected to the inner wall of the threaded sleeve 3. As the threaded rod 9 performs fixed-axis reciprocating rotation, the threaded sleeve 3 can drive the columnar block 2 to perform horizontal reciprocating movement on the inner wall of the sampling tube 1 under the action of the threaded rod 9.

[0025] Through the airbag 4 arranged on the sampling tube 1 and the vent 101 opened on the sampling tube 1, the vent 101 can connect the sampling tube 1 with the inner wall of the airbag 4. When sampling the vaginal secretions of the 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 column block 2 to move horizontally toward the direction close to the airbag 4 through the threaded sleeve rod 3, and the internal air pressure position of the sampling tube 1 close to the end of the airbag 4 is positive. Then, the column block 2 can fill the internal gas of the sampling tube 1 into the inner wall of the airbag 4 through the vent 101, so that the airbag 4 expands and supports the inner wall of the vagina, avoiding the problem of natural contraction of the inner wall of the vagina during the subsequent sampling of vaginal secretions, resulting in damage to the inner wall mucosa of the vagina, thereby improving the comfort and safety of sampling.

[0026] When the columnar block 2 is horizontally reset and moved in a direction away from the airbag 4, the above structure is simultaneously reset and moved in the opposite direction, so as to facilitate the subsequent removal of the sampling tube 1 from the patient's vagina after sampling.

[0027] Embodiment 2, based on embodiment 1, further comprises: The sampling mechanism includes a threaded sleeve rod 3, one end of which is horizontally movable and connected to a moving plate 10 away from the cylindrical block 2, and a fixed rod 11 is fixedly connected to the moving plate 10, and a connecting sleeve 12 is rotatably supported on the end of the fixed rod 11 away from the moving plate 10, and a circular plate 13 is fixedly connected to the outer contour of the end of the threaded sleeve rod 3 close to the moving plate 10, and a second spring 14 that guides the moving plate 10 to return to movement is fixedly connected to the opposite surface of the circular plate 13 and the moving plate 10.

[0028] The movable plate 10 is penetrated by the circular plate 13 and connected for horizontal movement. The end of the support rod 23 is rotatably connected to a connecting rod 22 that supports the connecting sleeve 12. The end of the connecting rod 22 away from the support rod 23 is rotatably connected to the connecting sleeve 12.

[0029] When in use, through the movable plate 10 set on the threaded sleeve 3, and the movable plate 10 axially moves and sleeves on the outer contour of the threaded sleeve 3, the movable plate 10 is in contact with the inner wall of the sampling tube 1 and is movably connected, and the circular plate 13 set on the threaded sleeve 3 is fixedly supported on the threaded sleeve 3, and the second spring 14 set on the circular plate 13 can support the position of the movable plate 10.

[0030] The fixing rod 11 is fixedly supported on the moving plate 10 through the fixing rod 11 set on the moving plate 10, and the connecting sleeve 12 is set on the fixing rod 11, so that the connecting sleeve 12 is connected to the fixing rod 11 for fixed-axis rotation. First, the medical staff fixes the sampling swab on the inner wall of the connecting sleeve 12, and through the supporting rod 23 set on the circular plate 13 and the connecting rod 22 set on the supporting rod 23, the connecting rod 22 can support the angle of the connecting sleeve 12 under the action of the supporting rod 23.

[0031] As the threaded sleeve 3 drives the columnar block 2 to move toward the direction close to the airbag 4, and the second spring 14 supports the movable plate 10, the threaded sleeve 3 can push the sampling swab on the connecting sleeve 12 to move toward the patient's vagina. When the movable plate 10 moves to the extreme position where the sampling tube 1 is away from one end of the threaded rod 9, and the sampling tube 1 supports the movable plate 10, the circular plate 13 can drive the support rod 23 to move toward the direction close to the connecting sleeve 12 under the push of the threaded sleeve 3, and the second spring 14 is squeezed and contracted under the action of the circular plate 13, so that 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, so that the sampling swab on the connecting sleeve 12 can be rotated to contact the inner wall of the vagina and sample the secretions.

[0032] When the threaded sleeve rod 3 drives the columnar block 2 to reset in the direction away from the airbag 4 , the above structure will reset in the opposite direction synchronously, so as to move the sampling swab after sampling on the connecting sleeve 12 into the sampling tube 1 .

[0033] Embodiment 3, based on embodiment 2, further comprises: The cylindrical block 2 is provided with an unlocking mechanism for unlocking the threaded sleeve 3, and the unlocking mechanism includes a moving rod 7 that is penetrated and horizontally movably connected to the inner wall of the cavity 201 on one side of the cylindrical block 2 close to the cavity 201, and 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 is provided on the moving rod 7 for movably supporting the slider 8.

[0034] When in use, the moving rod 7 provided on the columnar block 2 enables the moving rod 7 to be horizontally movable and connected on the columnar block 2, and the slider 8 provided on the locking block 5 is fixedly supported on the locking block 5, and the V-shaped groove 701 provided on the moving rod 7 enables the V-shaped groove 701 to movably support the slider 8. When the threaded rod 9 rotates clockwise to drive the threaded rod 9 to move to the extreme position toward the end close to the airbag, the moving rod conflicts with the inner wall of the sampling tube, so that the columnar block can drive the slider to move toward one end of the V-shaped groove. The slider pulls the locking block to move in the vertical direction away from the threaded sleeve rod under the action of the V-shaped groove, so that the first spring can be squeezed and contracted under the action of the locking block. At the same time, the locking block is out of contact with the locking groove and the threaded sleeve rod is unlocked, so that the threaded rod 9 drives the threaded sleeve rod to rotate synchronously. When the threaded rod 9 rotates counterclockwise, the locking block is reset 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, so that the threaded sleeve rod can drive the columnar block to reset toward the end away from the airbag.

[0035] As the circular plate 13 moves toward the direction approaching the movable plate 10, the cylindrical block 2 drives the movable rod 7 to contact and move with the inner wall of one end of the sampling tube 1, and the cylindrical block 2 can drive the slider 8 to move toward the end of the V-shaped groove 701, so that the slider 8 can pull the locking block 5 to move in 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, and at the same time, the locking block 5 moves out of contact with the locking groove 301, then the locking block 5 releases the locking state of the threaded sleeve 3, so that the threaded sleeve 3 can rotate synchronously with the threaded rod 9, so that the connecting sleeve 12 can mobilize the sampling swab to sample the vaginal wall secretions at multiple points, thereby improving the richness of the test samples and the accuracy of the test results.
