Description

Technical Field

[0001] This invention relates to the field of medical examination, and more particularly to a gynecological vaginal secretion sampling device. Background Technology

[0002] The main purpose of vaginal discharge sampling is to examine and assess the health of the female reproductive system.

[0003] For sampling vaginal secretions, traditional sampling methods mainly include cotton swab scraping and cervical brush sampling. During the sampling operation, the cotton swab or cervical brush head is inserted into the vagina, and then the cotton swab or cervical brush is rotated to scrape off the secretions attached to the vaginal wall, and then the sampling tool is removed.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] When sampling is required at deeper locations in the vagina, the cotton swab or cervical brush head is inserted into the vagina from the vaginal opening. During this process, the cotton swab or brush head is in constant contact with the vaginal wall, which causes secretions to stick to it. Therefore, it is not possible to sample secretions at different depths more accurately.

[0006] Therefore, it is necessary to provide a new gynecological vaginal secretion sampling device to solve the above-mentioned technical problems. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a gynecological vaginal secretion sampling device.

[0008] The gynecological vaginal secretion sampling device provided by this invention includes:

[0009] An adjustment assembly includes a positioning rod, one end of which is fixed with a positioning end, and a sliding sleeve that moves axially is also sleeved on the positioning rod.

[0010] A support assembly, fixed to a sliding sleeve, includes multiple ring-shaped elastic support bars, which together form a rugby ball-shaped support frame. The positioning end is located inside the support frame and can be moved to the outside of the support frame by axial movement of the sliding sleeve relative to the positioning rod.

[0011] The sampling component is a whole silicone sleeve, including a positioning sleeve and an end sleeve. Multiple elastic support bars are embedded in the positioning sleeve, and the end sleeve is fitted on the positioning end. The outer wall of the end sleeve has a brush head for sampling. The end sleeve can move with the positioning end inside and outside the support frame. When it is inside the support frame, it is completely covered by the positioning sleeve.

[0012] A locking assembly, which is mounted on a sliding sleeve, includes an insert that abuts against a positioning rod, thereby fixing the sliding sleeve to the positioning rod.

[0013] Preferably, a fixing sleeve is sleeved and fixed at the other end of the positioning rod, and the fixing sleeve has a pressing plate at one end away from the positioning rod and a first baffle at the other end;

[0014] The sliding sleeve is fixed with a second baffle at one end near the fixed sleeve, and a concentric connecting cylinder is integrally connected to the other end. The positioning rod is also fitted with a first spring that abuts against the first baffle and the second baffle, and the positioning end moves toward the inside of the support frame or has a tendency to move toward the inside of the support frame by the elastic force of the first spring.

[0015] Preferably, the outer circumferential wall of the positioning rod has multiple annularly distributed and axially arranged sliding grooves, while the inner circumferential wall of the sliding sleeve and the connecting cylinder has sliders corresponding to the number and position of the sliding grooves, and the sliders are embedded inside the sliding grooves.

[0016] Preferably, the outer circumferential wall of the sliding sleeve is further provided with a radially arranged through-hole, and a support block is integrally connected to the inner wall of the through-hole and near the inner circumferential wall of the sliding sleeve.

[0017] Preferably, the support assembly further includes a fixing ring, which is threaded to the outside of the connecting cylinder. One end of each of the multiple elastic support bars is welded and fixed to the outer circumferential wall of the fixing ring, while the other ends are not in contact, forming an opening through which the positioning end can pass.

[0018] Preferably, there is a folded section between the positioning sleeve and the end sleeve, and the non-fixed end of the elastic support strip passes through the interior of the positioning sleeve and extends to a position close to the folded section.

[0019] Preferably, the outer circumferential wall of the end cap also has multiple annular grooves for storing secretions.

[0020] Preferably, the locking assembly includes two fixing blocks integrally connected to the outer circumferential wall of the sliding sleeve and close to the through-hole. A positioning shaft mounted outside the through-hole is fixed between the two fixing blocks. The positioning shaft is equipped with a rotatable and cylindrical pressing seat. A paddle is integrally connected to the outer circumferential wall of the pressing seat.

[0021] Inside the through-hole, there is also a pressure seat that can move radially along the sliding sleeve. The upper end of the pressure seat has an arc-shaped groove, and the extrusion seat is embedded in the arc-shaped groove. The insert is integrally connected to the lower end of the extrusion seat. Positioning plates are integrally connected to both sides of the insert. The insert can be embedded in the sliding groove to achieve radial extrusion of the positioning rod.

[0022] A vertical rod is fixed to the upper end of the support block on the inner wall of the through-hole. The vertical rod passes through the positioning plate and is slidably connected to it. A second spring supporting the positioning plate is also sleeved on the vertical rod.

[0023] Preferably, the position where the positioning shaft connects to the extrusion seat is offset from the axis of the extrusion seat.

[0024] Compared with related technologies, the gynecological vaginal secretion sampling device provided by the present invention has the following beneficial effects:

[0025] The position of the positioning end relative to the support frame can be adjusted by the relative movement between the positioning rod and the sliding sleeve. This allows the end sleeve to be moved from the state covered by the positioning sleeve to the outside of the positioning sleeve, and the brush head can be used for sampling to achieve accurate sampling at different depths.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0040] Please see Figures 1 to 8 The present invention provides a gynecological vaginal secretion sampling device, which includes an adjustment component 1, a support component 2, a sampling component 3 and a locking component 4.

[0041] For adjustment component 1;

[0042] Please see Figure 4 The adjusting component 1 includes a positioning rod 11. One end of the positioning rod 11 is fixed with a positioning end 13, and the other end is sleeved and fixed with a fixing sleeve 14. The fixed sleeve 14 has a pressing plate 15 at the end away from the positioning rod 11, and a first baffle 16 is fixed at the other end. A sliding sleeve 17 that moves axially is also sleeved on the positioning rod 11. A second baffle 18 is fixed at the end of the sliding sleeve 17 close to the fixing sleeve 14, and a connecting cylinder 19 that is concentrically connected to the other end. A first spring 111 that abuts against the first baffle 16 and the second baffle 18 is also sleeved on the positioning rod 11.

[0043] It should be noted that: the positioning rod 11 is the supporting base of the entire device. One end of the positioning rod 11 has a fixed sleeve 14, one end of the fixed sleeve 14 has a pressing plate 15, and the other end has a positioning end 13. A sliding sleeve 17 that can move axially is also installed on the positioning rod 11. The sliding sleeve 17 has a second baffle 18. The second baffle 18 includes an annular plate, and the outer circumferential wall of the annular plate has an elliptical extension.

[0044] The principle of this structure is similar to that of a syringe. The thumb of the medical staff contacts the pressing plate 15, while the index and middle fingers contact the extensions on the second stop plate 18. When the pressing plate 15 is pressed, the sliding sleeve 17 can move relative to the positioning rod 11. A first spring 111 is also provided between the first stop plate 16 and the second stop plate 18. The first spring 111 is used for reset. After the external force acting on the pressing plate 15 is removed, the elastic force of the first spring 111 causes the sliding sleeve 17 to return to the starting position.

[0045] The fixed sleeve 14 is installed on the positioning rod 11 by means of a sleeve connection, so it can be disassembled. After the fixed sleeve 14 is disassembled, the sliding sleeve 17 can be removed. The split design of this structure is conducive to the replacement of any damaged structure, and also facilitates deep cleaning and disinfection of the device.

[0046] Please see Figure 4 , Figure 7 and Figure 8 The outer circumferential wall of the positioning rod 11 has multiple annularly distributed and axially arranged sliding grooves 12, while the inner circumferential wall of the sliding sleeve 17 and the connecting sleeve 19 has sliders 110 corresponding to the number and position of the sliding grooves 12, and the sliders 110 are embedded in the sliding grooves 12.

[0047] The outer circumferential wall of the sliding sleeve 17 is also provided with a radially arranged through-hole 112, and a support block 113 is integrally connected to the inner wall of the through-hole 112 and close to the inner circumferential wall of the sliding sleeve 17.

[0048] It should be noted that the outer circumferential wall of the positioning rod 11 has an axially arranged groove 12, and the sliding sleeve 17 has a slider 110 embedded in the groove 12, which can enhance the connection stability between the positioning rod 11 and the sliding sleeve 17.

[0049] For support component 2,

[0050] Please see Figure 5 The support component 2 includes a fixing ring 21, which is threaded to the outside of the connecting cylinder 19. Multiple ring-shaped elastic support bars 22 are welded and fixed to the outer circumference of the connecting cylinder 19. The other ends of the multiple elastic support bars 22 do not contact each other, forming an opening through which the positioning end 13 can pass, and together they form a rugby ball-shaped support frame.

[0051] It should be noted that in the support assembly 2, the fixing ring 21 is installed on the connecting cylinder 19 by means of threaded connection, so it can also be disassembled, which is convenient for maintenance and cleaning. The outer circumference of the fixing ring 21 has multiple elastic support bars 22, and the multiple elastic support bars 22 form a support frame, which is used to install and position the sampling assembly 3.

[0052] Because the fixed ring 21 is fixedly installed on the sliding sleeve 17, when the sliding sleeve 17 moves relative to the positioning rod 11, the entire support assembly 2 also moves relative to the positioning rod 11. This allows the positioning end 13 at one end of the positioning rod 11 to move relative to the support frame, while the non-fixed ends of the multiple elastic support bars 22 do not contact each other, thus forming an opening that allows the positioning end 13 to pass through the opening and move to the inside or outside of the support frame.

[0053] For sampling component 3, it is a single silicone sleeve;

[0054] Please see Figure 6 The sampling component 3 includes a positioning sleeve 31 and an end sleeve 33, with a folded section 32 between the positioning sleeve 31 and the end sleeve 33. The end sleeve 33 has a brush head 34 for sampling on its outer wall and also has multiple annular grooves 35 for storing secretions.

[0055] The non-fixed end of the elastic support bar 22 passes through the inside of the positioning sleeve 31 and extends to a position close to the folding section 32, while the end sleeve 33 is fitted onto the positioning end 13.

[0056] It should be noted that the sampling component 3 is mainly a whole silicone sleeve. Silicone will not cause harm to the human body, and at the same time, it has high flexibility, which makes it safer when it is inserted into the vagina for sampling.

[0057] The positioning sleeve 31 is connected to the elastic support strip 22, that is, the non-fixed end of the elastic support strip 22 is directly inserted into the positioning sleeve 31 (instead of putting the positioning sleeve 31 on the elastic support strip 22), so as to achieve a stable connection between the positioning sleeve 31 and the elastic support strip 22. The connection between the two can be reinforced by adhesive to prevent the positioning sleeve 31 from detaching from the elastic support strip 22. The end sleeve 33 is fitted on the positioning end 13. The outer circumferential wall of the positioning end 13 has a groove structure. An extension body can be set inside the end sleeve 33 to be embedded in the groove structure, so as to achieve a stable connection between the two.

[0058] Therefore, when the positioning end 13 is inside the support frame, the end sleeve 33 also enters the support frame and is completely covered by the positioning sleeve 31, forming an independent chamber. The non-fixed end of the elastic support strip 22 is located at the opening of the chamber. Under the elastic compression of the elastic support strip 22, the silicone material at the opening of the chamber is squeezed against each other, which can seal the chamber. Thus, during the process of the device entering or leaving the vagina, the secretions inside the vagina will not enter the chamber, achieving accurate sampling at different depths.

[0059] During sampling, the positioning end 13 is moved to the outside of the support frame by adjusting the adjustment component 1. At this time, the brush head 34 located on the outer wall of the end cap 33 is exposed. Medical staff can rotate the entire device by rotating their hands, and then scrape the secretions on the vaginal wall by rotating the brush head 34. A small amount of secretions will also be concentrated on the inner wall of the ring groove 35, thereby achieving sampling. After the force on the pressing plate 15 is removed, the positioning end 13 with the end cap 33 enters the support frame again and forms a closed chamber containing secretions again, which can then be removed.

[0060] Before the device is inserted into the vagina, a water-soluble lubricant can be applied to the outer wall of the positioning sleeve 31 to reduce the friction between the inner walls of the positioning sleeve 31, thereby improving the sampling efficiency and reducing damage to the vaginal wall.

[0061] For locking component 4;

[0062] Please see Figure 7 and Figure 8 The locking assembly 4 includes two fixing blocks 41 integrally connected to the outer circumference of the sliding sleeve 17 and located near the through opening 112. A positioning shaft 42 is fixed between the two fixing blocks 41 and mounted outside the through opening 112. The positioning shaft 42 is equipped with a rotatable and cylindrical pressing seat 43. The position where the positioning shaft 42 is connected to the pressing seat 43 is offset from the axis of the pressing seat 43. A paddle 44 is integrally connected to the outer circumference of the pressing seat 43.

[0063] Inside the through-hole 112, there is also a pressure seat 45 that can move radially along the sliding sleeve 17. The upper end of the pressure seat 45 has an arc groove 46, and the extrusion seat 43 is embedded in the arc groove 46. The insert 47 is integrally connected to the lower end of the extrusion seat 43. Positioning plates 48 are integrally connected to both sides of the insert 47. The insert 47 can be embedded in the sliding groove 12 to achieve radial extrusion of the positioning rod 11.

[0064] A vertical rod 49 is vertically fixed at the upper end of the support block 113 on the inner wall of the through-hole 112. The vertical rod 49 passes through the positioning plate 48 and is slidably connected to it. A second spring 410 supporting the positioning plate 48 is also sleeved on the vertical rod 49.

[0065] It should be noted that the locking component 4 is designed for the sliding sleeve 17, which can fix the sliding sleeve 17 to the positioning rod 11. Therefore, when the device needs to be cleaned and disinfected in the future, the positioning end 13 can be used to move the end sleeve 33 to the outside of the support frame. At this time, the outer surface of the entire silicone sleeve is exposed. Then, the locking component 4 locks the sliding sleeve 17, so that the device is covered. Thus, when cleaning and disinfecting in the future, medical staff do not need to continuously press the pressing plate 15, which reduces manpower consumption. At the same time, the cleaning operation will be more convenient and the cleaning effect will be better.

[0066] In the locking assembly 4, the paddle 44 can drive the pressing seat 43 to rotate. The pressing seat 43 and the pressure seat 45 are always in contact. The connection position between the pressing seat 43 and the positioning shaft 42 is off from the axis of the pressing seat 43. Therefore, when the pressing seat 43 is in contact with the pressure seat 45 at its near point, the pressure seat 45 is in its highest position. At this time, the insert 47 is not in contact with the positioning rod 11, so the sliding sleeve 17 can move relative to the positioning rod 11.

[0067] When the lever 44 drives the pressing seat 43 to rotate, so that the far point contacts the pressing seat 45, the pressing seat 45 moves toward the axis of the sliding sleeve 17, so as to drive the insert 47 to move together. At this time, the insert 47 is embedded in the sliding groove 12 and squeezes the positioning rod 11, thereby limiting the sliding sleeve 17 and stabilizing it on the positioning rod 11.

[0068] The vertical rod 49 is used to position the pressure seat 45 and the insert 47, while the second spring 410 can exert a spring force on them. When the pressing seat 43 moves from the far point to the near point to contact the pressure seat 45, the spring force of the second spring 410 causes the pressure seat 45 to move upward with the insert 47 to contact the restriction of the sliding sleeve 17.

[0069] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
