Description

Technical Field

[0001] The present invention relates to the technical field of secretion sampling, and particularly to a secretion sampling device. Background Art

[0002] In the field of gynecological medical diagnosis, accurately sampling secretions from key parts such as the vagina and cervix constitutes an important basis for the disease screening and diagnosis process. The vagina and cervix of women, as the front line of the reproductive system against the invasion of external pathogens, are extremely vulnerable to various diseases. Vaginitis, as one of the most common gynecological diseases, has various symptoms, including vaginal itching, abnormal odor of secretions, etc. However, different types of vaginitis, such as mycotic vaginitis and trichomonal vaginitis, have significant differences in treatment plans. Only through accurate secretion sampling and detection can the type of pathogen be determined, and then targeted treatment can be implemented.

[0003] However, in the early stage of gynecological secretion sampling, cotton swabs or scrapers were relied on, and potential lesion areas were missed. In addition, the secretions are not evenly distributed in the vagina and cervix, which may affect the accuracy of the test results. Moreover, the collected secretions may be contaminated by secretions from other parts after being taken out of the vagina, resulting in inaccurate test results. The present invention aims to provide a secretion sampling device to alleviate the above technical problems existing in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, that is, in the early stage of gynecological secretion sampling, cotton swabs or scrapers were relied on, and potential lesion areas were missed. In addition, the secretions are not evenly distributed in the vagina and cervix, which may affect the accuracy of the test results. Moreover, the collected secretions may be contaminated by secretions from other parts after being taken out of the vagina, resulting in inaccurate test results, and to propose a secretion sampling device.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A secretion sampling device, comprising a housing, a rocker is rotatably connected to the housing, a first cam, a second cam and a third cam are arranged on the surface of the rocker, a sampling mechanism for sampling secretion is arranged on the side surface of the housing, the sampling mechanism includes a blocking block arranged on the surface of the housing, an opening for the blocking block to block is formed on the surface of the housing, a fixed box is arranged at the bottom of the opening on the surface of the housing, a compression spring is fixedly connected to the bottom of the fixed box, one end of the compression spring away from the fixed box is fixedly connected with a compression inclined block, a support rod is fixedly connected above the compression inclined block, a fixing plate for placing an inner-groove gear is arranged on the side surface of the support rod, the inner-groove gear is in transmission connection with a connecting rod, the connecting rod is fixedly connected with a first bevel gear, the first bevel gear is meshed with a second bevel gear, the second bevel gear is in transmission connection with a sampling disc, one end of the blocking block is fixedly connected with a long rope, and one end of the long rope away from the blocking block is connected to one side of the support rod through a long groove, and the inner-groove gear is meshed with a fixed rack.

[0007] The above technical solution further includes:

[0008] One end of the compression spring away from the compression inclined block is fixedly connected with a fixing plate, a fixed box is fixedly connected above the fixing plate, a third roller and a second roller for the long rope to slide are arranged inside the long groove, a bottom plate is arranged at the bottom of the fixed box, a first roller for the third roller to slide is arranged above the bottom plate, the inner-groove gear is in transmission connection with a first belt, one end of the first belt away from the inner-groove gear is in transmission connection with a connecting rod, the second bevel gear is in transmission connection with a second belt, one end of the second belt away from the second bevel gear is in transmission connection with a sampling disc, a support rod is rotatably connected to the bottom of the sampling disc, and a fixed rack is fixedly connected above the bottom plate.

[0009] A stabilizing block is fixedly connected below the second bevel gear, and the stabilizing block is arranged on one side of the fixing plate.

[0010] A square cavity is arranged inside the housing, and both the second cam and the third cam inside the square cavity are used for squeezing the squeezing inclined block of the sampling mechanism.

[0011] A plurality of sampling openings are arranged on the surface of the housing, and the sampling openings on the surface of the housing are all aligned with one side of the second cam and the third cam.

[0012] A tension spring is fixedly connected to one side of the blocking block, and a stabilizing block is arranged on one side of the tension spring away from the blocking block.

[0013] The connecting rod is rotatably connected to the fixed plate. The design of the rotatable connection between the connecting rod and the fixed plate ensures that during the operation of the device, when the support rod rotates and drives the connecting rod to rotate through the first belt, the connecting rod can smoothly perform circular motion. This rotational connection method makes the force transmission more stable and efficient, reducing energy loss and jamming caused by inflexible connection. It ensures that the first bevel gear can rotate stably with the connecting rod, and then accurately mesh with the second bevel gear, driving the sampling plate to rotate smoothly for the secretion sampling operation, improving the stability and reliability of the entire sampling process.

[0014] A slope for the extrusion of the first cam is provided at the bottom of the extrusion wedge. The slope design at the bottom of the extrusion wedge is to cooperate with the extrusion action of the first cam. When the first cam rotates, its sharp part can smoothly push the extrusion wedge upward along the slope. This slope design enables the force exerted by the first cam on the extrusion wedge to be more evenly distributed, avoiding component damage or unsmooth movement caused by excessive local stress. At the same time, the guiding effect of the slope makes the upward movement of the extrusion wedge smoother, and it can accurately drive the upper support rod to slide upward, providing a stable power transmission basis for the subsequent sampling action and ensuring the smooth progress of the sampling operation.

[0015] The support rod is slidably connected to the fixed box and is also slidably connected to the fixed plate. The sliding connection method between the support rod and the fixed box as well as the fixed plate provides the necessary space and guidance for the up and down movement of the support rod. When the first cam extrudes the extrusion wedge, the support rod can smoothly slide upward along the slideways of the fixed box and the fixed plate, ensuring that the sampling plate can accurately rise to the sampling position. When the first cam no longer extrudes the extrusion wedge and the compression spring releases its elastic potential energy to make the extrusion wedge descend, the support rod can slide downward smoothly, quickly retracting the sampling plate into the fixed box. This sliding connection method ensures the flexibility and accuracy of the movement of the support rod, avoiding affecting the sampling effect and the normal operation of the device due to jamming or deviation.

[0016] A connection box for hanging a long rope is provided on one side of the support rod. The connection box on one side of the support rod is used to hang the long rope, and this design makes the connection between the long rope and the support rod more stable and reliable. During the upward movement of the support rod, the connection box can effectively drive the long rope to move, thereby pulling the blocking block to compress the tension spring and opening the sampling port below the blocking block. When the support rod descends, the connection box can ensure that the long rope accurately transmits the reverse force of the tension spring, causing the blocking block to close the sampling port in a timely manner.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, by means of the first cam, the second cam, and the third cam uniquely arranged on the rocker, it is possible to take samples of secretions from different parts of the vagina, namely the shallow, middle, and deep parts, greatly expanding the sampling range and effectively solving the problem that traditional cotton swabs or scrapers can only take samples at a single position and are prone to missing potential lesion areas. Through comprehensive analysis of samples at different depths, it is possible to better cope with the uneven distribution of secretions in the vagina and cervix, providing more comprehensive information for detection.

[0019] 2. In the present invention, after the sampling tray completes sampling, it can quickly retract inside the fixed box, reducing the possibility of the sample being contaminated by secretions from other parts during the sampling process from the vagina, avoiding sample contamination, thus ensuring the reliability of the detection results and providing a more trustworthy basis for clinical diagnosis.

[0044] In one embodiment, for the above-mentioned support rod 14, a connection box for hanging the long rope 26 is provided on one side of the support rod 14.

[0045] In this embodiment, the connection box on one side of the support rod 14 is used to hang the long rope 26, and this design makes the connection between the long rope 26 and the support rod 14 more stable and reliable. During the upward movement of the support rod 14, the connection box can effectively drive the long rope 26 to move, thereby pulling the blocking block 4 to compress the tension spring 5 and opening the sampling port below the blocking block 4. And when the support rod 14 descends, the connection box can ensure that the long rope 26 accurately transmits the reverse force of the tension spring 5, causing the blocking block 4 to close the sampling port in a timely manner.

[0046] The working principle of a secretion sampling device in the present invention is that first, the user gently inserts the outer shell 1 into the vagina of the examinee, and then performs secretion sampling, in order to Figure 2For example, a rocker 3 is arranged inside the outer shell 1, and a first cam 6, a second cam 7, and a third cam 8 are arranged on the surface of the rocker 3 corresponding to the light, medium, and deep vaginal secretions respectively, so as to ensure the accuracy of sampling the secretions of the examiner. The sharp parts of the first cam 6, the second cam 7, and the third cam 8 on the surface of the rocker 3 form an included angle of 120 degrees between every two of them. Taking the sampling at the shallow part of the vagina as an example, first, control the rocker 3 to rotate. Then, when the sharp part of the first cam 6 first presses the extrusion inclined block 9, it will push the extrusion inclined block 9 and compress the extrusion spring 11, so that the support rod 14 fixed above the extrusion inclined block 9 slides upward. And when sliding, a rack gear 13 is arranged at the bottom of the side fixing plate 12 of the support rod 14. Then, when the support rod 14 moves upward, the fixed rack 28 fixed on the bottom surface of the bottom plate 24 will engage with the rack gear 13 in the groove. Then, the support rod 14 rotates to drive the connecting rod 16 to rotate by using the first belt 15. The rotation of the connecting rod 16 will drive the first bevel gear 17 to engage with the second bevel gear 18. Then, the rotation of the second bevel gear 18 will drive the sampling plate 21 to rotate by using the second belt 20. Then, when the first cam 6 presses at the bottom of the extrusion inclined block 9, just when the sampling plate 21 rises and rotates at the same time to sample the vaginal secretions. When continuing to rotate the rocker 3, at this time, the first cam 6 no longer presses the extrusion inclined block 9, and then the extrusion inclined block 9 will release due to the elastic potential energy of the extrusion spring 11, so that the support rod 14 moves downward, and thus quickly retracts the sampling plate 21 that has completed sampling into the fixed box 10.

[0047] It is worth mentioning that a blocking block 4 is arranged above the outer shell 1. One end of the blocking block 4 is fixedly connected with a tension spring 5. One end of the blocking block 4 is provided with a long rope 26. The end of the long rope 26 far from the blocking block 4 then passes along the third roller 27 and then through the long groove 25, then passes under the second roller 23, and then passes under the first roller 22 and finally is connected to the fixed box specially fixed with the long rope 26 on one side of the top end of the support rod 14. Then, during the rising process, it will pull the blocking block 4 to compress the tension spring 5, and then the sampling port below the blocking block 4 is opened. When the above-mentioned first cam 6 no longer presses the extrusion inclined block 9 and the sampling plate 21 retracts into the fixed box 10, just when the tension spring 5 reversely pushes the blocking block 4, so as to realize the sampling of the secretions. Then, if continuing to rotate, it will be the turn of the second cam 7 to press the part of the extrusion inclined block 9 of the second group of sampling mechanisms, and then rotate another 120 degrees to sample the secretions at the deepest part of the vagina.
