In the description of the present invention, "plurality" means more than two, unless otherwise specifically defined.

[0020] like Figures 1-8 As shown, the present invention provides a vaginal wall disinfection and flushing device with a dilating function, comprising a transverse plate 10, a rotating disk 20, an expansion component 30, a control component 40, a spray component 50 and a locking component 60.

[0021] A semicircular groove 11 is formed on each side of the horizontal plate 10. An annular receiving groove 12 is formed longitudinally through the horizontal plate 10. A rotating disk 20 is disposed within and adapted to the annular receiving groove 12. The rotating disk 20 is rotatably connected to the inner wall of the annular receiving groove 12. A socket 21 is formed longitudinally through the center of the rotating disk 20. The rotating disk 20 also has a plurality of guide grooves 22 extending longitudinally and transversely therethrough. The guide grooves 22 are arranged at equal intervals along the circumference of the rotating disk 20.

[0022] There are multiple expansion assemblies 30, each corresponding to a plurality of guide slots 22. The expansion assemblies 30 include guide blocks 31 and expansion rods 32. The guide blocks 31 are in sliding contact with the inner walls of the guide slots 22. The expansion rods 32 are longitudinally mounted on top of the guide blocks 31 and are rotatably connected thereto.

[0023] The control assembly 40 is used to control the multiple expansion assemblies 30 to move inward or outward synchronously.

[0024] The spray assembly 50 includes a water collection box 51, a spray pipe 52, a drain hose 53, and a water pump. The water collection box 51 is positioned below the socket 21 and in close contact with the bottom of the rotating disk 20. The top of the water collection box 51 has a water inlet. The spray pipe 52 is longitudinally positioned within the socket 21 and fixedly connected to the water collection box 51. The outer circumference of the spray pipe 52 has multiple water outlet holes. The first end of the drain hose 53 is connected to the water collection box 51, and the second end of the drain hose 53 extends into the wastewater box. The water pump is used to deliver disinfectant into the spray pipe 52. Specifically, the water pump delivers disinfectant from the medicine tank into the spray pipe 52 via the water inlet hose 54.

[0025] The locking assembly 60 is used to lock the spray pipe 52 on the rotating disk 20 .

[0026] In the initial state, the spray assembly 50 is separated from other components of the device, and the guide block 31 and the expansion rod 32 are both close to the inner side of the guide groove 22 .

[0027] The specific use process of this device is: First, the patient is in a standing position, and the medical staff inserts multiple expansion rods 32 into the patient's vagina. At this time, the patient's legs are placed in the semicircular grooves 11 on both sides of the horizontal plate 10 to clamp the horizontal plate 10.

[0028] Then, the control component 40 is started, and the control component 40 controls the multiple expansion components 30 to move outward synchronously, so that the multiple expansion rods 32 will expand the patient's vagina.

[0029] Next, the medical staff inserts the spray tube 52 into the insertion hole 21 and then locks the spray assembly 50 on the rotating disk 20 through the locking assembly 60. At this time, the top of the water collection box 51 is in close contact with the bottom of the rotating disk 20.

[0030] Next, the medical staff activates the water pump, which draws disinfectant from the medicine tank and delivers it to the spray pipe 52 via the water inlet hose 54. The disinfectant then sprays out from the multiple outlets onto the inner wall of the patient's vagina, providing a disinfectant flush. The flushed disinfectant then flows through the jack 21 into the water collection box 51 and is ultimately discharged into the wastewater box via the drain hose 53.

[0031] Then, during the disinfection and flushing process, the medical staff can control the rotation of the rotating disk 20. In this way, on the one hand, the position of the expansion rod 32 will rotate and will not block the inner wall of the vagina, so that every surface of the inner wall of the vagina is flushed with the disinfectant; on the other hand, during the rotation of the rotating disk 20, the expansion rod 32 will roll on the inner wall of the patient's vagina, thereby covering the inner wall of the patient's vagina with disinfectant. Therefore, this manufacturing can disinfect and flush the inner wall of the patient's vagina in all directions, and the disinfection effect is better.

[0032] Finally, after the disinfection and flushing is complete, the medical staff unlocks the locking assembly 60 and removes the spray assembly 50. The control assembly 40 is activated, controlling the multiple expansion assemblies 30 to move inward synchronously until the guide blocks 31 and expansion rods 32 are close to the inner side of the guide groove 22. The expansion rods 32 are then removed from the patient's vagina.

[0033] In one embodiment, the control assembly 40 includes a rotating ring 41 and a plurality of springs 42 .

[0034] A rotating ring 41 is mounted outside the water collection box 51 of the spray pipe 52 and is rotatably connected to the bottom of the rotating disk 20. Multiple guide plates 43 are fixedly mounted on the outer circumference of the rotating ring 41. These guide plates 43 correspond to the guide slots 22 one by one. Each guide plate 43 is formed with an arcuate slot 44 extending longitudinally and transversely. A transmission rod 46 is positioned within each of these slots. The transmission rod 46 is adapted to fit within the slot, slidingly contacting the inner wall of the slot and securely connected to the guide block 31.

[0035] A plurality of springs 42 are respectively disposed in the plurality of guide slots 22 . A first end of the spring 42 is fixedly connected to an inner wall of the guide slot 22 , and a second end of the spring 42 is fixedly connected to the guide block 31 .

[0036] In this embodiment, the locking assembly 60 includes a fixing ring 61 and a plurality of locking plates 62 .

[0037] The fixing ring 61 is fixedly mounted on the spray pipe 52, and an annular locking groove 63 extending inward is formed on the outer circumference of the fixing ring 61. A plurality of locking plates 62 are respectively fixedly mounted on the plurality of expansion rods 32, and the ends of the locking plates 62 are inserted into the annular locking grooves 63.

[0038] In this embodiment, the top of the fixing ring 61 is provided with an annular guide surface 64 that is inclined downward and extends outward. The bottom of the locking plate 62 is provided with an arcuate guide surface 65 that is inclined upward and extends inward. The arcuate guide surface 65 is adapted to the annular guide surface 64.

[0039] In the initial state, the end of the locking plate 62 is located just above the insertion hole 21 , and the spring 42 is in a naturally extended state.

[0040] After inserting the spray tube 52 into the insertion hole 21, the medical staff pushes the spray tube 52 upward until the annular guide surface 64 contacts the curved guide surface 65. As the spray tube 52 continues to be pushed upward, the annular guide surface 64 and the curved guide surface 65 act to simultaneously push the multiple locking plates 62 outward by the fixing ring 61. The expansion rods 32 are also pushed outward, thereby stretching the patient's vaginal wall. As the spray tube 52 continues to be pushed upward, when the locking plates 62 align with the annular locking grooves 63, the springs 42 force the ends of the locking plates 62 firmly into the annular locking grooves 63. The springs 42 continue to exert an inward force on the guide blocks 31 and locking plates 62, thereby firmly locking the spray assembly 50 to the rotating disk 20. At this point, the multiple expansion rods 32 continue to stretch the patient's vaginal wall, and the top of the water collection box 51 is in close contact with the bottom of the rotating disk 20.

[0041] It is worth noting that this design allows medical staff to push the spray tube 52 upward. On the one hand, the annular guide surface 64 and the arc-shaped guide surface 65 can be used to automatically open the patient's vaginal wall by the multiple expansion rods 32; on the other hand, under the action of the spring 42, the end of the locking plate 62 is automatically inserted into the annular locking groove 63, thereby stably locking the spray assembly 50 on the rotating disk 20.

[0042] Because both the annular guide surface 64 and the annular locking groove 63 are annular in structure, medical personnel do not need to align the annular guide surface 64 with the arcuate guide surface 65, nor do they need to align the head of the locking plate 62 with the annular locking groove 63. During operation, medical personnel only need to push the spray tube 52 upward, and the arcuate guide surface 65 will automatically fit together with the annular guide surface 64. When the top of the water collection box 51 is in close contact with the bottom of the rotating disk 20, the end of the locking plate 62 will automatically insert into the annular locking groove 63, further facilitating the operation of medical personnel.

[0043] When the disinfection and flushing is completed and the spray tube 52 needs to be removed, the medical staff controls the rotating ring 41 to rotate, and the inner wall of the arc groove 44 will push the transmission rod 46 and the guide block 31 to move outward until the end of the locking plate 62 leaves the annular locking groove 63. Then the medical staff takes out the spray tube 52 downward and loosens the rotating ring 41. At this time, under the action of the spring 42, the guide block 31 and the expansion rod 32 are close to the inner side of the guide groove 22, and then the multiple expansion rods 32 can be taken out from the patient's vagina.

[0044] In one embodiment, the locking plate 62 is in close contact with the top of the rotating disk 20 .

[0045] When the spray assembly 50 is locked on the rotating disk 20 , the locking plate 62 is in close contact with the top of the rotating disk 20 . Therefore, the design of the locking plate 62 can also prevent the disinfectant solution after disinfection and flushing from flowing out of the guide groove 22 .

[0046] In one embodiment, a pull plate 45 is fixedly mounted on the rotating ring 41 to facilitate medical staff in controlling the rotation of the rotating ring 41 .

[0047] In one embodiment, a drive assembly 70 is further included. The drive assembly 70 includes a first gear 71, a rotating shaft 72, a second gear 73, and a handle 74. The first gear 71 is fixedly mounted on the rotating disk 20. The rotating shaft 72 is rotatably connected to the bottom of the horizontal plate 10. The second gear 73 is fixedly mounted on the rotating shaft 72 and meshes with the first gear 71. The handle 74 is fixedly mounted on the rotating shaft 72.

[0048] When the driving component 70 is working, the medical staff can control the rotation of the handle 74, and the handle 74 will drive the rotating shaft 72 to rotate. Under the action of the first gear 71 and the second gear 73, the rotating disk 20 will rotate, and then drive the multiple expansion rods 32 to rotate. The expansion rods 32 will roll on the patient's vaginal wall, thereby covering the patient's vaginal wall with disinfectant. Therefore, this manufacturing can disinfect and flush the patient's vaginal wall in all directions, and the disinfection effect is better.

[0049] In one embodiment, binding components 80 are respectively provided at both ends of the transverse plate 10 .

[0050] The binding assembly 80 includes a first binding strap 81 and a second binding strap 82, which are respectively arranged on either side of the horizontal plate 10. The first end of the first binding strap 81 is fixedly connected to the horizontal plate 10, and the second end of the first binding strap 81 is fixedly mounted with a Velcro loop 83. The first end of the second binding strap 82 is fixedly connected to the horizontal plate 10, and the second end of the second binding strap 82 is fixedly mounted with a Velcro hook 84.

[0051] After the patient's legs are placed in the semicircular grooves 11 on both sides of the horizontal board 10 and the horizontal board 10 is clamped, the medical staff can glue the Velcro fur surface 83 and the Velcro hook surface 84 together. In this way, the first binding strap 81 and the second binding strap 82 will bind the device to the patient's legs to prevent it from falling, making it easier for medical staff to operate.

[0052] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as illustrative and non-restrictive in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description, and all changes that come within the meaning and range of equivalents of the claims are intended to be included therein.

[0053] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
