[0023] Example:

[0024] like Figure 1 As shown, the utility model provides a vaginal dilator, including a lower duckbill plate 1 and an upper duckbill plate 2. The upper duckbill plate 2 is located above the lower duckbill plate 1, and the upper duckbill plate 2 is movably connected to the lower duckbill plate 1. A fixed block 3 is provided on one side of the lower duckbill plate 1 and the upper duckbill plate 2. The lower duckbill plate 1 is fixedly installed on the bottom of the fixed block 3. An adjusting rod 4 is vertically fixedly installed on the top of the upper duckbill plate 2. A limit bearing 6 is fixedly installed on the top of the fixed block 3. The adjusting rod 4 is passed through the limit bearing 6. The adjusting rod 4 is slidably connected to the limit bearing 6. A reset spring 5 is sleeved on the adjusting rod 4. The reset spring 5 abuts between the upper duckbill plate 2 and the fixed block 3. A flushing pipe 7 is movably clamped at the top of the upper duckbill plate 2. The flushing pipe 7 is located at the outer end of the upper duckbill plate 2 and is fixed with a water storage air bag 8.

[0025] like Figure 2 and Figure 3As shown, the lower duckbill plate 1 includes an integrally formed first support plate 11 and a first outward expansion plate 12, the upper duckbill plate 2 includes an integrally formed second support plate 21 and a second outward expansion plate 22, the fixed block 3 is located at the connection between the first support plate 11, the first outward expansion plate 12 and the second support plate 21, the second outward expansion plate 22, the bottom of the first support plate 11 is fixedly installed with a first mounting bracket 13 near the first outward expansion plate 12, the first mounting bracket 13 is movably connected with a lighting lamp 9, the top of the second support plate 21 is provided with a plurality of equidistantly distributed second mounting brackets 23, the flushing pipe 7 is movably connected to the second mounting bracket 23, the top of the fixed block 3 is provided with a mounting hole 31, and the limit bearing 6 is externally The ring is fixedly installed in the mounting hole 31, and the clamping wing plates 32 are fixedly installed on the left and right sides of the fixed block 3. The adjusting rod 4 includes an integrally formed connecting rod 41, a top plate 42, and a limit block 43. The top plate 42 is located at the top of the connecting rod 41, and the limit blocks 43 are located on both sides of the middle of the connecting rod 41. Key grooves 61 are provided on both sides of the inner ring of the limit bearing 6, and the limit blocks 43 are slidingly connected to the key grooves 61. An adjusting block 62 is fixedly installed on the top of the inner ring of the limit bearing 6. A cleaning nozzle 71 is fixedly installed on the end of the flushing pipe 7 away from the water storage airbag 8. The cleaning nozzle 71 is located at the end of the second support plate 21 away from the second outward expansion plate 22, and a water inlet 81 is fixedly installed on the water storage airbag 8.

[0026] It should be noted that in this embodiment, the surfaces of the first support plate 11 and the second support plate 21 are provided with anti-slip particles, and the anti-slip particles are hemispherical in structure. The lower duckbill plate 1, the upper duckbill plate 2, the fixing block 3, and the adjustment rod 4 are all made of plastic.

[0027] Assembly steps: First, the medical staff put on gloves, disinfect them, take the device out of the sterile bag, hold the clamping wing plates 32 on both sides of the fixed block 3 with one hand, and hold the top plate 42 with the other hand to pull it up. After the limit block 43 is separated from the key slot 61, rotate the adjusting block 62 to drive the key slot 61 and the limit block 43 to be misaligned. The bottom of the limit block 43 abuts against the top of the limit bearing 6, and the flushing pipe 7, water storage air bag 8, and lighting lamp 9 are disinfected. Open the water inlet 81, fill the water storage air bag 8 with cleaning liquid, clip the flushing pipe 7 into the second mounting bracket 23, adjust the position of the cleaning nozzle 71, and clip the lighting lamp 9 into the first mounting bracket 13, and then pull up the top plate 42 again, rotate the adjusting block 62, so that the key slot 61 corresponds to the position of the limit block 43, release the top plate 42, reset the limit block 43, and complete the assembly of the device.

[0028] Usage steps: First, the examinee needs to take the examination position, disinfect the device again, and then spray the lubricant on the surface of the first support plate 11 and the first expansion plate 12, and hold the device tightly on the clamping wings 32 on both sides of the fixed block 3 with your hands. Then, tilt the device 45 degrees and slowly insert it into the examinee's vagina. After it is fully inserted into the vagina, slowly return it to the right position, hold the top plate 42 by hand and slowly pull it up. After the limit block 43 is separated from the key slot 61, rotate the adjustment block 62 so that the key slot 61 and the limit block 4 are separated. 3 is misaligned, the limit block 43 abuts against the top of the limit bearing 6, the examiner's vagina is supported and opened, and the medical staff can observe and take samples from the channel supported by the first support plate 11 and the first outward expansion plate 12. After the inspection is completed, the top plate 42 is pulled upward again, the limit block 43 is separated from the limit bearing 6, and the adjustment block 62 is rotated to drive the key slot 61 to reset, and the top plate 42 is slowly lowered. The reset spring 5 resets and bounces up, driving the upper duckbill plate 2 to fall and reset, and then the device is taken out from the examiner's vagina to complete the inspection operation.

[0029] When flushing is required during the examination, the water storage airbag 8 is directly pressed to squeeze the cleaning liquid in the water storage airbag 8. The cleaning liquid enters the flushing tube 7 from the water storage airbag 8 and is finally transmitted to the cleaning nozzle 71 and sprayed out to clean the examinee's vagina. The cleaning liquid can also be added from the water injection port 81 during the process.

[0030] When the vagina is too dark and needs lighting, the lighting lamp 9 is started to illuminate the inside of the vagina.

[0031] After use, the flushing tube 7, water storage airbag 8, and lighting lamp 9 are removed from the device and can be used again after disinfection. The remaining parts can be directly discarded into the medical waste bin for recycling.

[0032] Working principle: the lower duckbill plate 1 and the upper duckbill plate 2 are installed on the fixed block 3. When supporting, the limit block 43 on the adjusting rod 4 abuts against the limit bearing 6. The position of the adjusting rod 4 is limited by the misalignment of the keyway 61 and the limit block 43, which drives the upper duckbill plate 2 to move upward to complete the support. The vagina can be observed and sampled from the channels of the first outer expansion plate 12 and the second outer expansion plate 22. The first mounting frame 13 is clamped with a fixed lighting lamp 9, which lights up to illuminate the vagina. Cleaning liquid is filled in the water storage airbag 8, and the water storage airbag 8 is pressed to squeeze out the cleaning liquid, which is sprayed from the cleaning nozzle 71 to clean the vagina. The operation is simple and can be assembled in advance. There is no need to place the dilator on the vagina. The first support plate 11 and the first outer expansion plate 12 are provided with anti-skid particles on the surface of the first support plate 11 and the first outer expansion plate 12, which can increase the friction with the inner wall of the vagina, and prevent the vagina from tightening and squeezing out the vaginal speculum during the inspection, causing harm to the examiner, thereby improving the safety of the inspection process. The material of the lower duckbill plate 1, the lower duckbill plate 2, the fixing block 3, and the adjusting rod 4 is set to plastic, which can be directly discarded into the medical waste bin for recycling after use. The production cost is low, which can reduce the use cost of the examiner and improve medical satisfaction.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
