[0042] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0043] The present utility model provides a vaginal dilator. Refer to Figure 1 - Figure 2 , which includes an upper vaginal dilating sheet 100, a lower vaginal dilating sheet 200, and a fixing mechanism 300. By providing the fixing mechanism 300, when the upper vaginal dilating sheet 100 and the lower vaginal dilating sheet 200 are opened to a certain angle, the upper vaginal dilating sheet 100 and the lower vaginal dilating sheet 200 are fixed, so that after the vaginal dilator is inserted into the vagina, the upper vaginal dilating sheet 100 and the lower vaginal dilating sheet 200 remain stable, achieving the purpose of facilitating use, reducing the workload, and improving work efficiency.

[0044] Exemplarily, one end of both the upper vaginal dilating sheet 100 and the lower vaginal dilating sheet 200 is arc-shaped. By providing that one end of both the upper vaginal dilating sheet 100 and the lower vaginal dilating sheet 200 is arc-shaped, vaginal scratching is prevented.

[0045] In one embodiment, refer to Figure 3 - Figure 5, the fixing mechanism includes a first connecting member 310, an internal gear ring 320, a second connecting member 330, a pawl 340 and a release mechanism 350. When using the vaginal dilator, press the upper dilating piece 100 and the lower dilating piece 200, so that the upper dilating piece 100 and the lower dilating piece 200 rotate around the axis of the rotating pair, so that one end opens at a certain angle. The pawl 340 projects outward from the radial hole under the elastic action of the elastic reset member 360. The pawl 340 continuously engages with the one-way ratchet teeth of the internal gear ring 320 during the pressing process. When the angle is appropriate, stop pressing. The pawl 340 engages with the one-way ratchet teeth of one of the internal gear ring 320, so that the upper dilating piece 100 and the lower dilating piece 200 are fixed in the open state, and the first connecting member 310 of the upper dilating piece 100 is connected to the upper dilating piece through a rotating pair. The lower dilating piece 200 and the lower dilating piece 200 are kept stable, which can achieve the purpose of being convenient to use, reduce the workload and improve the work efficiency. When it is necessary to take out the vaginal dilator, through the release mechanism 350, the pawl 340 is retracted into the radial hole, and the engagement between the pawl 340 and the internal gear ring 320 is released, so that the opening of the upper dilating piece 100 and the lower dilating piece 200 is reduced until they are closed.

[0046] Exemplarily, the first connecting member 310 is cylindrical.

[0047] Exemplarily, the second connecting member 330 is cylindrical or has a special-shaped structure, and the rotating connection between the second connecting member 330 and the first connecting member 310 and the upper dilating piece 200 is cylindrical.

[0048] In one embodiment, the first connecting member 310 is connected to the upper dilating piece 200 through a rotating pair. This makes the pressing of the upper dilating piece 100 and the lower dilating piece 200 smoother.

[0049] In one embodiment, the number of pawls 340 matches the number of radial holes. The number of radial holes is 3-6, and the present invention does not limit this. For example, in this embodiment, the number of pawls 340 and the number of radial holes are both 4.

[0050] In one embodiment, the release mechanism 350 includes a rotating member 351 and a third connecting member 352. When it is necessary to take out the vaginal dilator, by rotating the rotating member 351, the third connecting member 352 rotates and pulls the pawl 340 at the same time, the spring contracts, and the pawl 340 disengages from the one-way ratchet teeth on the internal gear, so that the openings of the upper dilating piece 100 and the lower dilating piece 200 are closed.

[0051] Exemplarily, the rotating member 351 is cylindrical. The second connecting member 330 is provided with a groove, and the rotating member 351 is installed at the groove and is rotatably connected to the second connecting member 330.

[0052] Exemplarily, the third connecting member 352 is a connecting rod or a pull rope.

[0053] In one embodiment, referring to Figure 5 , the release mechanism 350 further includes a rotating head 380 which is connected to the rotating member. When it is necessary to take out the vaginal dilator, rotate the rotating head 380. The rotation of the rotating head 380 drives the connecting member to rotate, and the connecting rod pulls the pawl 340, causing the spring to contract, so that the pawl 340 disengages from the one-way ratchet teeth on the internal gear, causing the openings of the upper vaginal dilating piece 100 and the lower vaginal dilating piece 200 to close, completing the use, thus achieving the purpose of being convenient to use.

[0054] In one embodiment, referring to Figure 2 , the vaginal dilator further includes a lighting lamp 400.

[0056] In one embodiment, the heating module 500 includes a heating wire 510, a battery 520 and a switch 530. The heating wire 510 is installed inside the upper vaginal dilating piece 100 and the lower vaginal dilating piece 200; the lower vaginal dilating piece 200 is provided with a handle 210, the battery 520 is installed inside the handle 210, and the switch 530 is installed at the bottom of the handle 210. Before use, turn on the switch 530, and the battery 520 supplies power to the heating wire 510, so that the heating wire 510 heats the upper vaginal dilating piece 100 and the lower vaginal dilating piece 200 to make their temperatures consistent with the body temperature, and then use is carried out.

[0057] Exemplarily, a charging hole 211 is provided at the bottom of the handle 210, and the battery 520 is charged through the charging hole 211.

[0058] In one embodiment, referring to Figure 1 - Figure 2 , the vaginal dilator further includes a plurality of air bags 600, an air charging pipe 700, a first one-way valve 800 and an air charging head 900. The air bags 600 are adhesively bonded to the surfaces of the upper vaginal dilating piece 100 and the lower vaginal dilating piece 200. A connecting pipe is connected to the bottom of the air bag 600, the connecting pipe is connected to the air charging pipe 700, the other end of the air charging pipe 700 is connected to the first one-way valve 800, and the bottom of the first one-way valve 800 is connected to the air charging head 900. After the vaginal dilator is fully dilated, the air charging head 900 inflates the air bags 600 to make them expand. When the first one-way valve 800 is in place, the gas in the air bags 600 cannot flow out in the reverse direction. The expansion of the air bags 600 fixes the vaginal dilator, which can achieve the purpose of preventing slipping, ensuring stability and improving work efficiency.

[0059] Exemplarily, the material of the airbag 600 is polyurethane, which has good elasticity and wear resistance.

[0060] Exemplarily, the inflation head 900 is a press - inflatable ball. A second one - way valve 910 is connected to the bottom of the press - inflatable ball, and the second one - way valve 910 prevents the gas in the press - inflatable ball from flowing out in the reverse direction.

[0061] In one embodiment, the air - charging pipe 700 is provided with a deflation valve 710. By setting the deflation valve 710, it is convenient to deflate.

[0062] In one embodiment, anti - slip pads 110 are bonded to the surfaces of the handle 210 and the upper vaginal dilator piece 100. By setting the anti - slip pads 110, it can prevent hand - slipping and facilitate operation.

[0063] In one embodiment, the heating module 500 further includes a control main board 540, which is used to control the heating wire 510 to maintain the temperature at 37 degrees after heating and not continue to heat to avoid scalding.

[0064] The specific implementation method is as follows:

[0065] Before use, turn on the switch 530 to make the heating wire 510 heat the upper vaginal dilator piece 100 and the lower vaginal dilator piece 200. After their temperature is consistent with the body temperature, put the vaginal dilator into the vagina. Then, press the handle 210 and the upper vaginal dilator piece 100 simultaneously, so that the upper vaginal dilator piece 100 and the lower vaginal dilator piece 200 rotate relative to each other. The pawl 340 extends outward from the radial hole under the elastic action of the elastic reset member 360, and the pawl 340 continuously meshes with the one - way ratchet teeth of the internal gear ring 320 during the pressing process. When the angle is appropriate, stop pressing. The pawl 340 meshes with the one - way ratchet teeth of one of the upper vaginal dilator piece 100 and the lower vaginal dilator piece 200 and the internal gear ring 320, so that the upper vaginal dilator piece 100 and the lower vaginal dilator piece 200 are fixed in the open state. Press the inflation head 900 to inflate the airbag 600, making it expand, and the expanded airbag 600 fixes the vaginal dilator. When disassembling, open the deflation valve 710, let the air out of the airbag 600, then rotate the rotating head 380. The rotation of the rotating head 380 drives the third connecting member 352 to rotate, and the third connecting member 352 pulls the pawl 340, the spring contracts, so that the pawl 340 disengages from the one - way ratchet teeth on the internal gear, and the opening of the upper vaginal dilator piece 100 and the lower vaginal dilator piece 200 closes, completing the use.
