Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a vaginal function exercise device. Background Technology

[0002] The vagina is a crucial part of the female reproductive system, playing a vital role not only in childbirth but also closely related to the urethra, anus, and pelvic floor muscles. With age, childbirth, and other factors, the function of the vagina and surrounding tissues may decline, leading to a range of health problems such as vaginal laxity, sexual dysfunction, and urinary incontinence. Therefore, maintaining or restoring vaginal function is essential. Vaginal delivery, in particular, can damage the pelvic floor muscles, reducing vaginal tone. As women age, declining estrogen levels can cause thinning of the vaginal walls, decreased elasticity, and even dryness and laxity. Lack of pelvic floor muscle exercise can result in insufficient support for the vagina and surrounding areas, impacting daily life. Conditions such as diabetes and obesity can affect muscle tone and elasticity. Vaginal rehabilitation is necessary after vaginal radiotherapy or other gynecological treatments. During this process, proper vaginal dilation techniques directly affect the rehabilitation outcome, including the control of dilation location, amount, and process. However, due to the involvement of gynecological treatments, patients often prefer to perform vaginal rehabilitation procedures themselves, but existing rehabilitation devices make it difficult for them to accurately perform these procedures.

[0003] In Chinese Patent 202122470497.1, the currently used vaginal douche allows patients and their families to insert it into the vagina for douching, but it does not have a dilation function. The commonly used vaginal speculum is a vaginal speculum used for gynecological examinations. This type of vaginal speculum requires a high level of medical literacy from the operator, and it is difficult for ordinary patients and their families to perform at home. The operation is inconvenient and it is difficult to achieve vaginal rehabilitation exercises. Therefore, this invention proposes a vaginal function exercise device to solve the problems existing in the prior art. Summary of the Invention

The lower pump body 14 pumps air to expand the expansion unit 23, and then the lower pump body 14 exhausts air to contract the expansion unit 23. This process is repeated to achieve the vaginal exercise function. The expansion unit 23 can be made of any one of the following materials: silicone, natural latex, TPU, TPE, synthetic latex, or polyurethane balloon.

[0030] The front end of the exercise body 2 is equipped with a camera 24. The camera 24 is electrically connected to the third port of the controller body 1 through the power supply signal line 5. A liquid nozzle 25 is fixedly installed at the front end of the insertion rod 22. The control panel 8 can realize functions such as setting the spraying time and spraying force of the liquid nozzle 25 by controlling the pump assembly. The control panel 8 is electrically connected to the camera 24, which can provide real-time image feedback to the display screen. The liquid nozzle 25 has its outlet end passing through the front end of the insertion rod 22 and is located on the side wall. The liquid nozzle 25's inlet end is connected to the outlet end of the connecting tube 21. The connecting tube 21 is located inside the insertion rod 22. The inlet end of the connecting tube 21 passes through the side wall of the tail end of the insertion rod 22 and is connected to the first connecting hose 3. The bottle contains saline or medication. Then, the top cap 12 is screwed into the bottle and placed upside down in the outer fixed bracket 11. When the upper pump body 9 is an air pump, by activating the upper pump body 9, air is pumped into the bottle. The air gathers at the top of the upside-down bottle, squeezing the saline or medication into the guide tube 13, and then pumping the liquid to the liquid nozzle 25 to achieve rinsing or medication administration. The air guide tube 20 is fixedly connected inside the fixed base 17. One end of the air guide tube 20 is connected to the hollow chamber inside the insertion rod 22, and the other end of the air guide tube 20 is connected to the second connecting hose 4.

[0031] The shooting end of the camera 24 is fixedly connected to the inner side of the front end of the insertion rod 22. The wiring end of the camera 24 is fixedly connected to the front end of the inner tube 19. The inner tube 19 is located inside the insertion rod 22. The bottom end of the inner tube 19 passes through the fixed base 17. The power supply signal line 5 is electrically connected to the camera 24 through the inner tube 19.

[0032] A pump body housing 26 is provided on the outer side of the lower pump body 14. An annular inner wall 27 is fixed inside the pump body housing 26. A turntable 28 is provided on the inner side of the annular inner wall 27. The turntable 28 is rotatably connected to the annular inner wall 27. Multiple sets of extrusion bearings 31 are rotatably connected to the inner side of the turntable 28 at intervals. A pump body hose 30 is provided between the extrusion bearings 31 and the inner wall of the annular inner wall 27. One end of the pump body hose 30 is connected to the second connecting hose 4, and the other end of the pump body hose 30 is connected to the built-in storage box 15.

[0033] A gear 29 is rotatably mounted on the top of the turntable 28. A rack 32 is meshed on one side of the gear 29. A guide block 33 is slidably connected to the rack 32. The guide block 33 is fixedly installed inside the pump body housing 26. A motor 34 is fixedly installed on one side inside the pump body housing 26. The output shaft of the motor 34 is connected to the crankshaft 35. A crankshaft connecting rod 10911 is hinged to one end of the crankshaft 35.

[0034] This vaginal function exerciser is used by the patient holding the exercise body 2 and inserting it into the vagina. Activating the controller body 1 causes the expansion unit 23 located in the middle of the exercise body 2 to expand and contract, thus exercising the vagina and restoring its function. Simultaneously, the controller body 1 pumps saline solution or therapeutic medication to the exercise body 2, and the flushing tubing at the front of the exercise body 2 irrigates or administers medication to the vagina, facilitating vaginal cleaning and medication treatment. The bottle contains saline solution or medication. The top cap 12 is then screwed into the bottle and placed upside down in the outer fixing bracket 11. When the upper pump body 9 is an air pump, activating it pumps air into the bottle, where the air gathers... The top of the inverted bottle squeezes saline or medication into the guide tube 13, and then the liquid is pumped to the liquid nozzle 25 for rinsing or medication administration. By starting the motor 34, the crankshaft 35 and crankshaft connecting rod 10911 drive the rack 32 to reciprocate in the guide block 33. The rack 32 drives the turntable 28 through the gear 29, which in turn drives several compression bearings 31 to move and compress the pump body hose 30. One end of the pump body hose 30 is connected to the atmosphere or the built-in storage tank 15, pumping fluid into the insertion rod 22 to expand the expansion unit 23. The reciprocating motion of the rack 32 changes the rotation direction of the turntable 28, thereby changing the pumping direction and realizing the expansion and contraction of the expansion unit 23. By changing the speed of the motor 34, the expansion and contraction frequency of the expansion unit 23 can be changed.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
