Description

Technical Field

[0001] This invention relates to the field of endocrine sampling, and more specifically, to a sampling device for reproductive endocrine function. Background Technology

[0002] Reproductive endocrinology is a branch of endocrinology, also known as reproductive medicine. Reproductive endocrinology examinations generally refer to examinations of reproductive medicine and reproductive health, mainly including examinations of the reproductive system and endocrine system. They are primarily aimed at the pathological changes, functional disorders, and diagnosis and treatment of diseases in the reproductive and endocrine systems.

[0003] When performing reproductive endocrine sampling on female patients, the traditional sampling method is for medical staff to hold a cotton swab and insert it into the patient's vagina to collect secretions. This sampling method requires the medical staff to manually control the force of the operation based on their operating experience, which can lead to low sampling accuracy. The prior art discloses a sampling device for examining the female reproductive system (publication number CN211583074U). By rotating the rotating rod with a handle, the rotating teeth move synchronously through the rotating groove when the rotating rod rotates, thereby rotating out the sampling brush for collection. At the same time, the user can also know the length rotated in according to the scale set on the rotating rod, so as to avoid causing harm to the patient. While existing technologies can improve the accuracy of endocrine sampling to some extent by observing the length of movement, traditional sampling devices require breaking off the part of the swab tip that has absorbed secretions after sampling and then placing it in a special test tube for analysis. However, manually breaking the swab requires applying external force to the swab shaft, and secretions on the surface of the swab may spill during the breaking process, affecting the quality of the sampling and easily causing pollution to the surrounding environment. In addition, the broken swab shaft can easily tear the gloves of medical staff, posing a significant risk of occupational exposure. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a sampling device for reproductive endocrine disorders. By setting a separation component, the sampling swab with attached secretions can be automatically separated from the sampling device, thereby effectively reducing the risk of accidental dripping of the attached material from the sampling swab surface, greatly simplifying the manual breaking process, effectively increasing the difficulty of separating the sampling swab, and significantly reducing the risk of occupational exposure for medical personnel.

[0010] Furthermore, the second arc-shaped plate is semi-circular and is perpendicular to the first arc-shaped plate at a 90-degree angle.

The sliding plate is located directly above the second arc-shaped plate.

[0011] Furthermore, a separation assembly is provided on the upper side of the connecting rod.

(4) This scheme sets up a flipping component, and the rotation of the movable rod can make the connecting rod one deflect in multiple directions, so that the sampling swab can be kept in contact with the vaginal wall, thereby enabling the collection of secretions from the patient's vagina in multiple directions, thus expanding the collection range and greatly improving the accuracy of endocrine collection. (5) By setting up the sampling component, the sampling cotton yarn and the collection hole are staggered to extract secretions of different viscosities, which can greatly improve the functionality of the sampling device. After sampling, the secretions adsorbed in the absorbent cotton inside the air chamber can be squeezed out of the drain pipe by squeezing the sampling swab, so that the two secretions can be sampled and analyzed separately, which can further improve the accuracy of secretion sampling and detection.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 9 A sampling device for reproductive endocrinology includes a sampling tube 11, the sampling tube 11 having a hollow internal structure and an open upper end, an expansion component being provided on the outer side of the sampling tube 11, the expansion component including a connecting block 13 fixedly connected to the outer surface of the sampling tube 11, the number of connecting blocks 13 being two sets and symmetrically distributed, a support plate 14 being fixedly connected to the upper outer surface of the connecting block 13, and a pushing component being provided on the inner side of the sampling tube 11; The pushing component includes a limiting plate 23 fixedly connected to the inner surface of the sampling tube 11. The limiting plate 23 is annular. A guide sleeve 26 is fixedly connected to the middle of the limiting plate 23. There are two sets of the limiting plate 23 and the guide sleeve 26, which are arranged in parallel. A movable rod 24 is slidably attached to the middle of the guide sleeve 26. The lower end of the movable rod 24 extends through to the outside of the sampling tube 11. A flipping component is provided at the upper end of the movable rod 24. The flipping assembly includes an arc-shaped plate 31 fixedly connected to the upper end of the movable rod 24. The arc-shaped plate 31 is semi-circular. A spindle 32 is rotatably connected to the inner side of the arc-shaped plate 31. A spindle 36 is fixedly connected to the middle of the outer surface of the spindle 32. The spindle 32 and the spindle 36 form a cross structure. An arc-shaped plate 33 is rotatably connected to the outer surface of the spindle 36.

[0021] By adopting the above technical solution, when performing reproductive endocrine sampling on female patients, the vaginal opening is first dilated by the dilation component to facilitate better sampling of secretions in the cervical canal. The pushing component can work with the flipping component to adjust the position of the sampling device, so that the sampling device can fully adhere to and contact the inner wall of the cervical canal, thereby effectively improving the quality of sampling.

[0022] like Figure 1 and Figure 2 As shown, there are two sets of support plates 14, which are symmetrically distributed. A pin 15 is rotatably connected between the two sets of support plates 14. The pin 15 passes through the front and rear ends of the sampling tube 11 and is rotatably connected to the sampling tube 11. There are two sets of pins 15, which are symmetrically distributed. An outer sleeve 12 is fixedly connected to the outer surface of the pin 15. The outer sleeve 12 is semi-circular.

[0023] The outer sleeve 12 is located outside the sampling tube 11. An expansion tube 18 is fixedly connected to the upper outer surface of the outer sleeve 12. The expansion tube 18 is duckbill shaped. There are two sets of expansion tubes 18, which are symmetrically distributed. A tension spring 17 is fixedly connected to the inner surface of the expansion tube 18. The end of the tension spring 17 away from the expansion tube 18 is fixedly connected to the upper end of the sampling tube 11. Ear plates 16 are fixedly connected to the outer surfaces of the two sets of outer sleeves 12 respectively.

[0024] By adopting the above technical solution, when using the dilation assembly, the dilation tube 18 in its closed state is first inserted into the patient's vagina. The duckbill-shaped dilation tube 18 can reduce discomfort during the operation. Then, the operator presses down on the ear plate 16. After being subjected to force, the ear plate 16 will cause the outer tube 12 to flip outward and simultaneously drive the pin 15 to rotate. The support plate 14 can support the rotation of the pin 15. The support plate 14 is fixed to the surface of the retrieval tube 11 by the connecting block 13. During the flipping process, the two sets of outer tubes 12 will synchronously drive the two sets of dilation tubes 18 to move in opposite directions. The vaginal opening is dilated by rotating the dilator tube 18 at a certain angle, which makes it easier for medical staff to observe the sampling position between the two sets of dilator tubes 18. This allows for the extraction of secretions from the predetermined location and improves the flexibility and accuracy of the sampling process. After the sampling is completed, the operator gradually releases the ear plate 16. At this time, the outer tube 12 will move towards the sampling tube 11 under the elastic force of the tension spring 17, so that the two sets of dilator tubes 18 are brought together again. Then, the dilator tube 18 is removed from the patient's vagina to complete the endocrine sampling operation.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, a conveyor wheel 21 is fixedly connected to the outer surface of the pin 15 inside the sampling tube 11. A friction wheel 22 is fixedly connected to the outer surface of the conveyor wheel 21. The friction wheel 22 is made of elastic rubber material. There are two sets of friction wheels 22, which are symmetrically distributed on both sides of the movable rod 24. The friction wheel 22 rotates and fits in contact with the outer surface of the movable rod 24. A pull ring 25 is fixedly connected to the lower end of the movable rod 24. The pull ring 25 has a circular ring structure.

[0026] By adopting the above technical solution, the expansion component will drive the push component to start synchronously when it runs. When the pin 15 rotates with the outer sleeve 12, the pin 15 drives the conveyor wheel 21 to rotate synchronously. Thus, the conveyor wheel 21 drives the two sets of friction wheels 22 to rotate in opposite directions. During the rotation of the friction wheels 22, the moving rod 24 will be conveyed, so that the moving rod 24 moves upward and extends out of the expansion tube 18 at the same time as the expansion tube 18 expands. The conveyor wheel 21, made of elastic rubber material, can greatly increase the friction between it and the moving rod 24. The limiting plate 23 in the inspection tube 11 can fix and support the guide sleeve 26. The guide sleeve 26 can slide and support the moving rod 24, so that the moving rod 24 can slide more smoothly. The pull ring 25 can facilitate the operator to rotate the moving rod 24, improving the convenience of the operation.

[0027] like Figure 4 , Figure 6 and Figure 7As shown, the second arc plate 33 is semi-circular and is perpendicular to the first arc plate 31 at a 90-degree angle. A connecting rod 35 is fixedly connected to the upper end of the second arc plate 33, and a sliding plate 34 is fixedly connected to the outer surface of the connecting rod 35. The sliding plate 34 is located directly above the second arc plate 33.

[0028] By adopting the above technical solution, the moving rod 24 will drive the arc plate 31 to move synchronously during its upward movement. At the same time, the arc plate 31 can be supported by the inner spindle 32. The spindle 32 supports the arc plate 33 through the spindle 36. As the arc plate 31 and the arc plate continue to move upward, the arc plate 33 will drive the connecting rod 35 to move upward synchronously, thereby driving the slider 34 to move synchronously. Since the dilation tube 18 is duckbill-shaped and gradually narrows at the top, the sliding plate will slide and contact the inner surface of the dilation tube 18 during its upward movement. At this time, the dilation tube 18 will apply a certain pressure to the sliding sleeve, thereby causing the slider 34 to drive the connecting rod 35 to rotate at a certain angle. At this time, the operator can turn the moving rod 24 out through the pull ring 25. The rotation of the moving rod 24 can cause the connecting rod 35 to deflect in multiple directions, thereby enabling the collection of secretions from the patient's vagina in multiple directions. This can expand the collection range and greatly improve the accuracy of endocrine collection.

[0029] like Figure 5 , Figure 8 and Figure 9 As shown, a separation assembly is provided on the upper side of the connecting rod 35. The separation assembly includes a separation seat 41 that is slidably connected to the upper side of the outer surface of the connecting rod 35. A groove 42 is embedded in the lower end of the separation seat 41. The upper end of the connecting rod 35 is located inside the groove 42 and slidably fits into contact with the groove 42. A slot 45 is embedded in the inner side of the separation seat 41. The slot 45 is conical and its lower end is connected to the upper side of the groove 42. A guide plate 43 is fixedly connected to the outer surface of the upper end of the separation seat 41. The guide plate 43 is distributed in a funnel shape.

[0030] Friction blocks 46 are slidably connected to the inner side of the slot 45. There are three sets of friction blocks 46 arranged in a ring. A partition 44 is fixedly connected to the upper end of the inner surface of the slot 45. The partition 44 is circular. A connecting rod 491 is slidably attached to the middle of the partition 44. The friction blocks 46 are in contact with the outer surface of the connecting rod 491. A spring 49 is fixedly connected to the lower outer surface of the friction blocks 46.

[0031] A locking block 48 is fixedly connected to the lower end of the inner surface of the slot 45. The lower end of the spring 49 is fixedly connected to the upper end of the locking block 48. The spring 49 is located outside the second connecting rod 491. A top rod 47 is fixedly connected to the upper end of the first connecting rod 35. The upper end of the top rod 47 is in contact with the lower end of the second connecting rod 491. A locking groove 52 is provided at the lower end of the second connecting rod 491. The locking block 48 is located inside the locking groove 52 and is in sliding contact with the locking groove 52. The number of locking grooves 52 and locking blocks 48 are several sets and are distributed in a ring.

[0032] A sampling component is provided on the upper side of the second connecting rod 491. The sampling component includes a sampling swab 53 fixedly connected to the upper end of the second connecting rod 491. The sampling swab 53 is located inside the expansion tube 18. A collection hole 55 is opened on the outer surface of the sampling swab 53. The number of collection holes 55 is several groups and they are arranged in a ring. An air cavity 57 is embedded in the inner side of the sampling swab 53. An absorbent cotton 58 is fixedly connected to the inner surface of the air cavity 57.

[0033] A drain pipe 59 is embedded and fixedly connected to the lower outer surface of the sampling swab 53. A collection groove 56 is opened on the outer surface of the sampling swab 53. A sampling cotton yarn 54 is fixedly connected to the inner surface of the collection groove 56. The sampling cotton yarn 54 is in the shape of a ring. The number of sampling cotton yarns 54 is several sets and they are staggered with the collection hole 55.

[0034] By adopting the above technical solution, during sampling, connecting rod 1 35 drives connecting rod 2 491 to move synchronously through separating seat 41. Connecting rod 2 491 then extends the sampling swab 53 from the dilation tube 18 into the patient's vagina, bringing the surface of the sampling swab 53 into contact with the vaginal wall. Simultaneously, the flipping component, in conjunction with the pushing component, rotates the sampling swab 53, ensuring full contact between the surface of the sampling swab 53 and the vaginal wall. The sampling cotton gauze 54 on the surface of the sampling swab 53 absorbs vaginal secretions, and the receiving groove 56 engages and limits the sampling cotton gauze 54. Meanwhile, secretions with lower viscosity will enter the air chamber 57 inside the sampling swab 53 through the collection hole 55 on the surface of the sampling swab 53. They will be absorbed by the absorbent cotton 58 inside the air chamber 57. The sampling cotton yarn 54 and the collection hole 55 are staggered to extract secretions of different viscosities, which can greatly improve the functionality of the sampling device. After sampling, the secretions adsorbed in the absorbent cotton 58 inside the air chamber 57 can be squeezed out from the drain pipe 59 by squeezing the sampling swab 53. This allows for the separate sampling and analysis of the two types of secretions, which can further improve the accuracy of secretion sampling and detection. After the inspection is completed, the sampling swab 53 can be quickly separated by the separation assembly. When the separation assembly is running, the lower side of the second connecting rod 491 is located in the slot 45 of the separation seat 41. Since the slot 45 is conical, the friction block 46 inside the slot 45 is tightly attached to the outer surface of the second connecting rod 491 under the action of gravity and the elastic force of the spring 49. Thus, the friction between the friction block 46 and the second connecting rod 491 is used to lock and fix the second connecting rod 491. The lower side of the second connecting rod 491 is provided with a locking groove 52. At the same time, the second connecting rod 491 is locked and limited by the locking block 48 inside the slot 45 through the locking groove 52. Thus, the separation seat 41 can drive the second connecting rod 491 to rotate synchronously. When the second connecting rod 491 is separated from the separation seat 41 after the inspection is completed, the expansion tube 18 is expanded to both sides again. At this time, the first connecting rod 35 and the second connecting rod 491 will move upward synchronously. During the upward movement of the second connecting rod 491, it will drive the guide plate 43. Synchronous movement: After the guide plate 43 moves upward a certain distance, it will contact the inner wall of the expansion tube 18, thereby preventing the guide plate 43 and the separation seat 41 from continuing to move through the expansion tube 18. At this time, since the connecting rod 35 will continue to move upward and slide into the groove 42, the sliding of the connecting rod 35 will drive the top rod 47 to move synchronously. Thus, the top rod 47 will drive the connecting rod 35 to move upward, causing the locking groove 52 on the lower side of the connecting rod to separate from the locking block 48. During the movement of the connecting rod 35, the friction block 46 will move upward through friction. After the friction block 46 moves upward, the friction between it and the connecting rod 491 will gradually decrease, thereby causing the connecting rod 491 to gradually disengage from the separation seat 41. This enables the automatic separation of the sampling swab 53 from the sampling device, greatly simplifying the manual breaking process and effectively increasing the difficulty of separating the sampling swab 53, reducing the risk of occupational exposure for medical personnel.

[0035] Instructions for use: First, operate the dilation assembly. The dilation tube 18 is rotated at a certain angle to dilate the patient's vaginal opening, facilitating observation of the sampling location by medical personnel between the two sets of dilation tubes 18. The pin 15 drives the delivery wheel 21 to rotate synchronously, which in turn drives the two sets of friction wheels 22 to rotate in opposite directions. During rotation, the friction wheels 22 transport the movable rod 24, causing the dilation tube 18 to dilate while the movable rod 24 moves upward and extends out of the dilation tube 18. Then, the surface of the sampling swab 53 contacts the inner wall of the patient's vagina. The dilation assembly is then rotated. The rotation of the movable rod 24 allows the connecting rod 35 to deflect in multiple directions, enabling the collection of vaginal secretions from multiple directions. In conjunction with the pushing component, it drives the sampling swab 53 to rotate, ensuring the surface of the swab 53 fully contacts the vaginal wall. The sampling cotton gauze 54 on the surface of the swab 53 then absorbs the vaginal secretions. After collection, the separation component gradually disengages the connecting rod 491 from the separation seat 41, thus achieving automatic separation of the sampling swab 53 from the sampling device, effectively increasing the difficulty of separating the sampling swab 53.
