Description

Technical Field

[0001] This invention relates to the field of diagnostic measurement technology, and more particularly to a vaginal muscle strength tester. Background Technology

[0002] The vaginal muscle strength tester is a core medical device for screening pelvic floor dysfunction and assessing pelvic floor muscle strength. It mainly consists of a detection probe, a signal acquisition unit, and a data processing terminal. During the test, the probe is inserted into the vagina to collect data on vaginal wall contraction pressure, thereby assessing the pelvic floor muscle function. During the probe insertion process, due to individual differences in vaginal tightness, direct insertion can easily cause difficulty in insertion, leading to discomfort and pain for the patient. Therefore, in clinical practice, it is usually necessary to use a personal lubricant to reduce frictional resistance and make the vaginal wall fit the probe surface better, thereby improving the accuracy of pressure detection.

[0003] Currently, most conventional vaginal muscle strength testing devices use manual external application of lubricant. The lubricant coating is unevenly distributed and has limited continuous lubrication effect, making it difficult to maintain a stable lubrication effect throughout the entire probe insertion process. Some devices with built-in lubrication channels have a single fluid output mode, which can only achieve unidirectional fluid output and is difficult to automatically switch lubrication modes before and after probe insertion. Furthermore, the fluid output flow rate is difficult to control, and the rapidly flowing lubricant can easily stimulate the vaginal wall to produce reflexive muscle contractions, which can easily interfere with the accuracy of muscle strength test data.

[0004] Meanwhile, the telescopic transmission of existing test instrument probes is mostly a rigid direct-drive structure. It lacks flexible buffering at the moment of contact and start-stop, which easily generates rigid impact. This causes strong stimulation to the vaginal wall tissue, which increases the patient's foreign body sensation and discomfort. Some patients with low tolerance find it difficult to cooperate to complete the test, which restricts the testing efficiency and data integrity. Summary of the Invention

[0005] In view of the problems of uneven and poor continuity of manual external lubrication and the single output mode of the built-in liquid circuit in the existing technology, a vaginal muscle strength tester is proposed.

[0006] Its purpose is to automatically switch between lubrication at the tip and circumferential lubrication of the side wall before and after probe insertion, regulate the flow rate of lubricating fluid, and avoid the fluid flow stimulating the vaginal wall to reflexively contract.

[0007] The technical solution of the present invention is a vaginal muscle strength tester, including a frame, a placement frame fixedly disposed on the outer wall of the frame, and a test component slidably disposed on the outer wall of the placement frame; the test component includes a frame component slidably disposed on the outer wall of the placement frame, a driving component fixedly disposed on the inner wall of the frame component, a movable component slidably disposed on the inner wall of the frame component, a connecting component slidably disposed on the inner wall of the top of the frame component, a rotating component rotatably disposed on the inner wall of the frame component, and a fixing component fixedly disposed on the inner wall of the frame component; The frame component includes a fixed shell slidably disposed on the outer wall of the placement rack, a feed groove opened on the outer wall of the fixed shell, a connecting groove opened on the inner wall of the fixed shell, a mounting hole opened on the top of the fixed shell, a sliding groove opened on the inner wall of the top of the fixed shell, a liquid outlet opened on the side wall of the fixed shell, and a liquid draining hole opened on the top of the fixed shell. The movable component includes a sliding block slidably disposed on the inner wall of the fixed shell, a pushing structure slidably disposed on the inner wall of the sliding block, a connecting ring fixedly disposed on the outer wall of the sliding block, and an air guiding structure fixedly disposed on the outer wall of the connecting ring.

[0008] Furthermore, the driving component includes a servo motor fixedly disposed on the inner wall of the fixed housing, a threaded rod fixedly disposed on the output end of the servo motor, a fixing block fixedly disposed on the inner wall of the fixed housing, a limiting block fixedly disposed on the inner wall of the fixed housing, and a liquid passage pipe fixedly disposed on the inner side wall of the fixed housing.

[0009] Furthermore, the connecting groove is connected to the feed groove, and the inner wall of the sliding block is threadedly connected to the outer wall of the threaded rod.

[0010] Furthermore, the pushing structure includes a contact rod slidably disposed on the inner wall of the sliding block, an airbag fixedly disposed on the outer wall of the contact rod, and a limiting tube fixedly disposed on the side wall inside the sliding block, wherein the outer wall of the airbag is fixedly connected to the inner wall of the sliding block.

[0011] Furthermore, the air guiding structure includes a fixed ring fixedly disposed on the outer wall of the connecting ring, a sliding ring slidably disposed on the inner side wall of the fixed ring, a movable ring fixedly disposed on the inner side wall of the sliding ring, and air guiding holes symmetrically and alternately opened on the outer wall of the movable ring.

[0012] Furthermore, the connecting component includes a sliding tube slidably disposed on the inner wall of the fixed shell, a connecting frame fixedly disposed on the inner side wall of the sliding tube, a blocking block fixedly disposed on the top of the connecting frame, and a compression spring fixedly disposed on the outer side wall of the sliding tube, wherein the outer wall of the top of the compression spring is fixedly connected to the inner wall of the top of the fixed shell.

[0013] Furthermore, the rotating component includes a rotating disk rotatably disposed on the inner wall of the fixed shell, a clearance hole opened on the inner wall of the central shaft of the rotating disk, through holes symmetrically opened on the inner wall of the rotating disk, and a torsion spring fixedly disposed on the outer wall of the bottom of the rotating disk.

[0014] Furthermore, the fixing component includes a fixing post fixedly disposed on the inner wall of the fixing shell, a top hole opened inside the top of the fixing post, and a side hole opened on the side wall of the fixing post, wherein the side hole is connected to the drain hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Before the probe is inserted, the lubricant flows out from the top drain hole through the fixed column to complete the lubrication of the probe tip. After insertion, the top liquid path is automatically cut off by the sliding block and the blocking block is linked to switch to circumferential lubrication through the side wall drain hole. At the same time, the cavity volume can be adjusted and the liquid flow speed can be controlled by the displacement of the sliding block to avoid the liquid flow stimulation causing muscle contraction and ensure the accuracy of muscle strength test data.

[0016] 2. The contact rod is equipped with an airbag structure. The initial contact is a soft buffer. As the squeezing force increases, the airbag is gradually compressed and the support rigidity is gradually increased to avoid rigid impact. It is adapted to the contact tolerance of human tissue and effectively reduces the foreign body sensation and discomfort during the testing process.

[0017] 3. The air guiding structure adopts an interlaced air guiding hole design. When the sliding block moves, the airflow is limited to form movement damping, which can effectively reduce the vibration and jerking sensation at the moment of start and stop, making the probe extension and retraction process smoother and more comfortable for the subject, while ensuring the positional accuracy during the test.

[0018] 4. The linear movement of the sliding block synchronously drives the switching of the fluid path and the conversion of the drainage mode. The rotating disk with the torsion spring reset realizes the control of the fluid path opening and closing, which is convenient for daily maintenance and clinical operation.

Detailed Implementation

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figure 1 - Figure 5 and Figure 7 According to the first embodiment of the present invention, a vaginal muscle strength tester is provided, including a frame 1, a placement frame 2 fixedly connected to the outer wall of the frame 1, and a test assembly 3 slidably connected to the outer wall of the placement frame 2. The test assembly 3 includes a frame component 31 slidably connected to the outer wall of the placement frame 2, a driving component 32 fixedly connected to the inner wall of the frame component 31, a movable component 33 slidably connected to the inner wall of the frame component 31, a connecting component 34 slidably connected to the inner wall of the top of the frame component 31, a rotating component 35 rotatably connected to the inner wall of the frame component 31, and a fixing component 36 fixedly connected to the inner wall of the frame component 31.

[0023] The frame component 31 includes a fixed shell 311 slidably connected to the outer wall of the placement rack 2, a feed groove 312 opened on the outer wall of the fixed shell 311, a connecting groove 313 opened on the inner wall of the fixed shell 311, a mounting hole 314 opened on the top of the fixed shell 311, a sliding groove 315 opened on the inner wall of the top of the fixed shell 311, a liquid outlet hole 316 opened on the side wall of the fixed shell 311, and a drain hole 317 opened on the top of the fixed shell 311; the movable component 33 includes a sliding block 331 slidably connected to the inner wall of the fixed shell 311, a pushing structure 332 slidably connected to the inner wall of the sliding block 331, a connecting ring 333 fixedly connected to the outer wall of the sliding block 331, and an air guiding structure 334 fixedly connected to the outer wall of the connecting ring 333.

[0024] Reference Figure 1 - Figure 6 The driving component 32 includes a servo motor 321 fixedly connected to the inner wall of the fixed housing 311, a threaded rod 322 fixedly connected to the output end of the servo motor 321, a fixing block 323 fixedly connected to the inner wall of the fixed housing 311, a limiting block 324 fixedly connected to the inner wall of the fixed housing 311, and a liquid passage pipe 325 fixedly connected to the inner side wall of the fixed housing 311. The connecting groove 313 is connected to the feed groove 312, and the inner wall of the sliding block 331 is threadedly connected to the outer wall of the threaded rod 322.

[0025] Specifically, under normal conditions, lubricating fluid enters the cavity formed by the top of the movable part 33 and the inner cavity of the fixed shell 311 through the fluid inlet tube 325. After the probe is inserted into the vagina, the servo motor 321 starts and drives the threaded rod 322 to rotate, causing the sliding block 331 to move away from the top along the inner wall of the fixed shell 311. The cavity volume expands accordingly, and the flow rate of the lubricating fluid slows down to avoid the fluid flow stimulating muscle contraction and interfering with the detection results. The fixed block 323 and the limiting block 324 limit the displacement of the sliding block 331. After the probe is in place, the servo motor 321 drives the threaded rod 322 in the opposite direction, causing the sliding block 331 to move towards the top of the fixed shell 311. The cavity volume shrinks, and the lubricating fluid remaining inside is squeezed outward.

[0026] Reference Figure 1 - Figure 8 The pushing structure 332 includes a contact rod 3321 slidably connected to the inner wall of the sliding block 331, an airbag 3322 fixedly connected to the outer wall of the contact rod 3321, and a limiting tube 3323 fixedly connected to the side wall inside the sliding block 331. The outer wall of the airbag 3322 is fixedly connected to the inner wall of the sliding block 331.

[0027] Specifically, the probe is wrapped in the outer layer of the fixed shell 311. During the upward movement of the sliding block 331, the contact rod 3321 of the pushing structure 332 first contacts the connecting frame 341 of the connecting component 34. The contact rod 3321 is subjected to a reaction force and retracts into the sliding block 331, squeezing the airbag 3322 along the limiting tube 3323. This causes the airbag 3322 to be gradually compressed and the supporting rigidity of the contact rod 3321 to be gradually increased until the contact rod 3321 is blocked by the limiting tube 3323, achieving a rigid support state.

[0028] Reference Figure 1 - Figure 9 The air guiding structure 334 includes a fixed ring 3341 fixedly connected to the outer wall of the connecting ring 333, a sliding ring 3342 slidably connected to the inner side wall of the fixed ring 3341, a movable ring 3343 fixedly connected to the inner side wall of the sliding ring 3342, and air guiding holes 3344 symmetrically and alternately opened on the outer wall of the movable ring 3343.

[0029] Specifically, during the up-and-down movement of the sliding block 331, the connecting ring 333 drives the air guiding structure 334 to move synchronously. When the sliding block 331 moves upward, the gas in the upper chamber of the air guiding structure 334 is compressed, pushing the sliding ring 3342 and the movable ring 3343 to slide downward along the inner wall of the fixed ring 3341. Among the two rows of air guiding holes 3344 that are staggered on the side wall of the movable ring 3343, the upper row of air guiding holes 3344 is blocked by the inner wall of the fixed ring 3341, and the lower row of air guiding holes 3344 moves to below the fixed ring 3341. The air in the upper chamber can only flow slowly through the top air guiding hole 3344 and the lower row of air guiding holes 3344. By limiting the airflow velocity, the movement damping is increased, the vibration of the sliding block 331 at the moment of starting and stopping is weakened, the movement stability is improved, the discomfort during the detection process is reduced, and the accuracy of the muscle strength test data is ensured.

[0030] Example 2, refer to Figure 1 - Figure 10 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the connecting component 34 includes a sliding tube 342 slidably connected to the inner wall of the fixed shell 311, a connecting frame 341 fixedly connected to the inner side wall of the sliding tube 342, a blocking block 343 fixedly connected to the top of the connecting frame 341, and a compression spring 344 fixedly connected to the outer side wall of the sliding tube 342. The outer wall of the top of the compression spring 344 is fixedly connected to the inner wall of the top of the fixed shell 311.

[0031] Specifically, as the sliding block 331 continues to move upward, the rigid contact rod 3321 pushes the connecting frame 341 and the sliding tube 342 upward along the sliding groove 315, compressing the compression spring 344. Simultaneously, the connecting frame 341 drives the top blocking block 343 to move upward, blocking the top hole 362 and side hole 363 of the fixing column 361, cutting off the liquid path of the top drain hole 317. At this time, the lubricant flows out from the bottom hole on the side of the fixing column 361 in the mounting hole 314, flows into the flow channel where the drain hole 316 is located through the opening on the side wall of the sliding tube 342, and finally is discharged outward from the drain hole 316 on the side wall of the fixing shell 311, realizing circumferential side wall lubrication, adapting to the lubrication needs of the vaginal wall. The discharge pressure can be adjusted by controlling the moving speed of the sliding block 331 to adapt to different usage scenarios.

[0032] Reference Figure 1 - Figure 10 The fixing component 36 includes a fixing post 361 fixedly connected to the inner wall of the fixing shell 311, a top hole 362 opened inside the top of the fixing post 361, and a side hole 363 opened on the side wall of the fixing post 361. The side hole 363 is connected to the drain hole 317.

[0033] Specifically, before the probe is inserted into the human body, lubricating fluid flows upward through the cavity into the fixing post 361 of the fixing component 36. After entering the interior of the post through the top hole 362, it flows out through the side hole 363 on the side wall and connects to the drain hole 317, and is discharged outward from the top of the fixing shell 311, thus lubricating the outer wall of the probe tip and reducing frictional discomfort during insertion. The rest of the structure is the same as that in Embodiment 1.

[0034] Example 3, referring to Figure 1 - Figure 11 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the rotating component 35 includes a rotating disk 351 rotatably connected to the inner wall of the fixed shell 311, a clearance hole 352 opened in the inner wall of the central axis of the rotating disk 351, through holes 353 symmetrically opened in the inner wall of the rotating disk 351, and a torsion spring 354 fixedly connected to the outer wall of the bottom of the rotating disk 351.

[0035] Specifically, under normal conditions, the torsion spring 354 drives the rotating disk 351 to maintain its initial position. The through hole 353 on the rotating disk 351 is aligned and connected with the fluid pipe 325. The lubricant enters the cavity through the through hole 353 and the fluid pipe 325. The clearance hole 352 in the middle of the rotating disk 351 provides a through clearance space for the threaded rod 322 to avoid structural interference. When it is necessary to cut off the fluid passage, rotating the rotating disk 351 causes the through hole 353 to be misaligned with the fluid pipe 325, which blocks the lubricant passage. After releasing the handle, the torsion spring 354 drives the rotating disk 351 to automatically reset, restoring the fluid passage connection. The remaining structure is the same as that in Embodiment 2.

[0036] Based on embodiments 1-3, the working principle of the present invention is as follows: During operation, the frame 1 and the placement frame 2 serve as the overall supporting foundation. The test component 3 is slidably placed along the outer wall of the placement frame 2. The test component 3 uses the fixed shell 311 of the frame component 31 as a carrier, and internally carries the driving component 32, the moving component 33, the connecting component 34, the rotating component 35, and the fixing component 36. This completes the switching of lubricating fluid passages, the adjustment of flow rate, the multi-directional drainage control, and the pneumatic buffering during movement, thereby improving the comfort and stability of the testing process.

[0037] Before use, connect the lubricant delivery pipe to the feed groove 312 on the side wall of the fixed shell 311. The lubricant flows into the chamber where the rotating part 35 is located through the connecting groove 313. Under normal conditions, the torsion spring 354 drives the rotating disk 351 to maintain its initial position. The through hole 353 on the rotating disk 351 is aligned and connected with the liquid pipe 325. The lubricant enters the cavity formed by the top of the moving part 33 and the inner cavity of the fixed shell 311 through the through hole 353 and the liquid pipe 325. The clearance hole 352 in the middle of the rotating disk 351 provides a through clearance space for the threaded rod 322 to avoid structural interference. When it is necessary to cut off the liquid path, rotate the rotating disk 351 to make the through hole 353 and the liquid pipe 325 misaligned, which can block the lubricant passage. After releasing, the torsion spring 354 drives the rotating disk 351 to automatically reset and restore the liquid path connection.

[0038] Before the probe is inserted into the human body, the lubricating fluid flows upward through the cavity into the fixing post 361 of the fixing component 36. After entering the interior of the post through the top hole 362, it flows out through the side hole 363 on the side wall and connects to the drain hole 317. It is discharged outward from the top of the fixing shell 311 to lubricate the outer wall of the probe tip and reduce the friction discomfort during the insertion process.

[0039] After the probe is inserted into the vagina, the servo motor 321 starts to drive the threaded rod 322 to rotate, which drives the sliding block 331 to move away from the top along the inner wall of the fixed shell 311. The cavity volume expands accordingly, the flow rate of the lubricating fluid slows down, and the fluid flow stimulates the muscle contraction to avoid interfering with the detection results. The fixed block 323 and the limiting block 324 form a limiting constraint on the displacement stroke of the sliding block 331.

[0040] The probe is wrapped in the outer layer of the fixed shell 311. After the probe is in place, the rotating disk 351 is rotated to cut off the lubricant supply passage. The servo motor 321 drives the threaded rod 322 in the reverse direction, which drives the sliding block 331 to move towards the top of the fixed shell 311. The cavity volume is reduced, and the lubricant left inside is squeezed outward. During the upward movement of the sliding block 331, the contact rod 3321 of the pushing structure 332 first contacts the connecting frame 341 of the connecting component 34. The contact rod 3321 is subjected to a reaction force and contracts into the sliding block 331, squeezing the airbag 3322 along the limiting tube 3323. This causes the airbag 3322 to be gradually compressed and the support rigidity of the contact rod 3321 to be gradually increased until the contact rod 3321 is blocked by the limiting tube 3323, achieving a rigid support state.

[0041] As the sliding block 331 continues to move upward, the rigid contact rod 3321 pushes the connecting frame 341 and the sliding tube 342 upward along the sliding groove 315, compressing the compression spring 344. Simultaneously, the connecting frame 341 drives the top blocking block 343 to move upward, blocking the top hole 362 and side hole 363 of the fixing column 361, cutting off the liquid path of the top drain hole 317. At this time, the lubricant flows out from the bottom hole on the side of the fixing column 361 in the mounting hole 314, flows into the flow channel where the drain hole 316 is located through the opening on the side wall of the sliding tube 342, and finally is discharged outward from the drain hole 316 on the side wall of the fixing shell 311, realizing circumferential side wall lubrication, adapting to the lubrication needs of the vaginal wall. The discharge pressure can be adjusted by controlling the moving speed of the sliding block 331 to adapt to different usage scenarios.

[0042] During the up-and-down movement of the sliding block 331, the air guiding structure 334 is synchronously displaced through the connecting ring 333. When the sliding block 331 moves upward, the gas in the upper chamber of the air guiding structure 334 is pressurized, pushing the sliding ring 3342 and the movable ring 3343 to slide downward along the inner wall of the fixed ring 3341. Among the two rows of air guiding holes 3344 that are staggered on the side wall of the movable ring 3343, the upper row of air guiding holes 3344 is blocked by the inner wall of the fixed ring 3341, and the lower row of air guiding holes 3344 moves to below the fixed ring 3341. The air in the upper chamber can only flow slowly through the top air guiding hole 3344 and the lower row of air guiding holes 3344. By limiting the airflow velocity, the movement damping is increased, the vibration of the sliding block 331 at the moment of starting and stopping is weakened, the movement stability is improved, the discomfort during the testing process is reduced, and the accuracy of the muscle strength test data is ensured.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
