[0028] The use steps of the present invention are as follows: the first flexible skeleton 104 and the second flexible skeleton 107 in the device are made of nickel-titanium alloy or other materials with both elastic deformation ability and structural stability. The specific materials can be selected according to actual conditions. The first airbag 105 and the second airbag 108 are supported by the first flexible skeleton 104 and the second flexible skeleton 107 with a crescent-shaped internal cross-section. Therefore, the first airbag 105 and the second airbag 108 in the normal state will form a smaller spherical shape when they are close to each other. By holding the circular shell 101, it is convenient to deliver the first airbag 105 and the second airbag 108 into the vagina of the parturient, and the opposite surfaces of the first airbag 105 and the second airbag 108 are concave to form an elliptical space. When the first airbag 105 and the second airbag 108 are in a crescent-shaped cross-section, the first airbag 105 and the second airbag 108 are in a crescent-shaped cross-section. After the second airbag 108 is delivered into the vagina of the parturient, the first liquid delivery tube 301 is connected to the external disinfectant supply pipeline. The disinfectant injected from the outside will enter the annular water bag 304 through the first liquid delivery tube 301, the second liquid delivery tube 302 and the third liquid delivery tube 303 in sequence. As the disinfectant is continuously injected, the annular water bag 304 will expand and the micropores on the surface will open, thereby allowing the disinfectant to be sprayed into the vagina of the parturient for cleaning and disinfection. During this process, the air pump 201 is started. When the first solenoid valve 210 is opened and the second solenoid valve 211 is closed, the air intake end 203, the second hard tube 206, the second air tube 207 and the second airbag 108 deep in the vagina are in a connected state, and the air outlet end 202, the first hard tube 204, the first air tube 20 5 and the first airbag 105 are in a connected state. When the first electromagnetic valve 210 is closed and the second electromagnetic valve 211 is opened, the air outlet end 202 and the first hard tube 204 are in a blocked state, the air intake end 203 and the second hard tube 206 are in a blocked state, and the air outlet end 202, the first connecting tube 208, the second air tube 207 and the second airbag 108 deep in the vagina are in a connected state, and the air intake end 203, the second connecting tube 209, the first air tube 205 and the first airbag 105 are in a connected state. Therefore, by alternately controlling the opening and closing of the first electromagnetic valve 210 and the second electromagnetic valve 211, the air pump 201 can alternately extract the air in the first airbag 105 and the second airbag 108 through the air intake end 203 and alternately send the air into the corresponding state. In the second airbag 108 and the first airbag 105, when the first airbag 105 is injected with air and expands, it will cling to the inner wall of the vagina to form a solid state, and at the same time achieve the purpose of fixing the cylinder 102 in the vagina. Similarly, when the second airbag 108 is injected with air and expands, it will achieve the purpose of fixing the piston rod 103 inside the vagina. When the first airbag 105 and the second airbag 108 are in a negative pressure contraction state, the volume is small, which is convenient for moving inside the vagina. In this process, the cylinder 102 is started to drive the piston rod 103 to cooperate and expand. When the annular water bag 304 on the surface of the piston rod 103 needs to move deep into the vagina, the second airbag 108 is controlled to expand, the first airbag 105 is contracted, and the cylinder 102 controls the piston rod 103 to contract.At this time, the first airbag 105 will move toward the second airbag 108 in a fixed state, and then the first airbag 105 will expand and be fixed, and the second airbag 108 will shrink. The cylinder 102 controls the piston rod 103 to extend and push the second airbag 108 into the deep of the vagina. This reciprocating process can make the annular water bag 304 on the surface of the piston rod 103 move into the deep of the vagina. Conversely, the first airbag 105 expands first, and the second airbag 108 shrinks later. Finally, the cylinder 102 controls the piston rod 103 to shrink and make the second airbag 108 move continuously toward the outside of the vagina, thereby achieving the purpose of driving the annular water bag 304 to move outward. Under the cooperation of each other, the annular water bag 304 can be driven to move freely inside the vagina by the alternately expanding and shrinking first airbag 105 and second airbag 108, and the movement process is The peristaltic state will not cause abrasions to the vaginal mucosa, which is beneficial to the recovery of the mother. When the air pump 201 inflates the first airbag 105, the first hard tube 204, the first air tube 205, the second hard tube 206, the second air tube 207, the first connecting tube 208, the second connecting tube 209, the first solenoid valve 210 and the second solenoid valve 211 cooperate to completely utilize the gas in the second airbag 108. Conversely, when inflating the second airbag 108, the gas inside the first airbag 105 is completely utilized, and there is no need to connect it to the outside air through a pipeline. This reduces the number of pipelines and improves practicality. In this device, the pipelines and devices that penetrate the first airbag 105 and the second airbag 108 are sealed at the connection to avoid air leakage.

[0029] Example 2: Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, the difference between the embodiment and the drain assembly 4 is that the drain assembly 4 includes a rectangular shell 401 , a handle 402 is fixedly connected to the top of the rectangular shell 401 , and a diaphragm pump 404 is installed at the bottom of the rectangular shell 401 .

[0030] A three-way proportional valve 405 is installed at the input end of the diaphragm pump 404. The two input ends on the front and bottom of the three-way proportional valve 405 are fixedly connected to the first water suction pipe 406 and the second water suction pipe 411 respectively. The front end of the first water suction pipe 406 is fixedly connected to the first connecting pipe 407. The first connecting pipe 407 is installed inside the first airbag 105 and both ends extend to the outside. The front end of the first connecting pipe 407 is fixedly connected to the second connecting pipe 410.

[0031] The second connecting tube 410 is fixedly connected to an annular shell 408 at one end away from the first connecting tube 407. The second connecting tube 410 and the annular shell 408 are both bonded to the front outer surface of the first airbag 105. A plurality of hose heads 409 are fixedly connected to the annular shell 408 at equal intervals.

[0032] The usage steps of the present invention are as follows: when using the device to flush and clean the vagina of a parturient, when the disinfectant remains in the vagina and is difficult to flow out in time, since the input end of the diaphragm pump 404 is connected through the three-way proportional valve 405, the first water suction pipe 406, the first connecting pipe 407, the second connecting pipe 410 and the annular shell 408 on the surface of the first airbag 105, the inside of the annular shell 408 will be in a low-pressure state after the diaphragm pump 404 is started, so that the hose head 409 around the annular shell 408 generates suction. At this time, the distance between the hose head 409 and the inner wall of the vagina is small, and the generated suction can absorb the excess disinfectant in time and discharge it to the outside through the output end of the diaphragm pump 404, avoiding the problem of excessive disinfectant flowing into the deep part of the vagina and being difficult to clean, causing infection, thereby improving the nursing effect of the device. In addition, by holding the handle 402, it is convenient to take the rectangular shell 401 and the diaphragm pump 404 inside.

[0033] Example 3: Figure 1 Figure 10 As shown, the difference between the embodiment and the embodiment is that the front end of the second water suction pipe 411 is fixedly connected to a plane shell 412, the interior of the plane shell 412 is a cavity and openings 413 are provided on the outer surface near the bottom.

[0034] A fixing sleeve 403 is fixedly connected to the top of the rectangular shell 401, and the rear end of the first liquid delivery tube 301 passes through the inside of the fixing sleeve 403. An air injection nozzle 106 is fixedly connected to the rear surface of the first airbag 105 near the edge, and a sealing cap is threadedly connected to the rear end of the air injection nozzle 106. The cross-sections of the first flexible skeleton 104 and the second flexible skeleton 107 are both crescent-shaped.

[0035] The steps of using the present invention are as follows: when the diaphragm pump 404 is started to absorb the excess disinfectant inside the vagina, the three-way proportional valve 405 controls the flow rate through the input end of the diaphragm pump 404, so that the suction force generated by the diaphragm pump 404 is two and acts on the first water suction pipe 406 and the second water suction pipe 411 at the same time, and the suction force generated by the second water suction pipe 411 is larger. At this time, since the second water suction pipe 411 and the plane shell 412 are in a connected state and the plane shell 412 is surrounded by openings 413, the plane shell 412 is placed on the bed outside the vaginal opening of the parturient. The suction force generated by the openings 413 on the surface of the plane shell 412 can absorb the disinfectant that naturally flows out and falls on the bed and then discharge it to a designated position through the output end of the diaphragm pump 404, thereby solving the problem that a large amount of disinfectant will remain on the bed during the cleaning of the parturient's vagina and improving the use effect of the device. The gas injection nozzle 106 is mainly used to replenish gas into the first airbag 105.

[0036] The effect and working principle achieved by the entire mechanism are as follows: the relatively arranged first airbag 105 and the second airbag 108 in the device are supported by the first flexible skeleton 104 and the second flexible skeleton 107 with a crescent-shaped internal cross-section. Therefore, the first airbag 105 and the second airbag 108 in the normal state will form a smaller sphere when close to each other. By holding the circular shell 101, the first airbag 105 and the second airbag 108 can be conveniently delivered into the vagina of the parturient, and the opposite surfaces of the first airbag 105 and the second airbag 108 are concave to form an elliptical space. After the first airbag 105 and the second airbag 108 are delivered into the vagina of the parturient, the first liquid delivery tube 301 is connected to the external disinfectant supply pipeline, and the disinfectant injected from the outside will pass through in sequence. The disinfectant enters the annular water bag 304 through the first liquid delivery pipe 301, the second liquid delivery pipe 302 and the third liquid delivery pipe 303. As the disinfectant is continuously injected, the annular water bag 304 will expand and the micropores on the surface will open, so that the disinfectant is sprayed into the vagina of the parturient for cleaning and disinfection. In this process, the air pump 201 is started. When the first solenoid valve 210 is opened and the second solenoid valve 211 is closed, the air suction end 203, the second hard tube 206, the second air tube 207 and the second air bag 108 deep in the vagina are in a connected state, and the air outlet end 202, the first hard tube 204, the first air tube 205 and the first air bag 105 are in a connected state. When the first solenoid valve 210 is closed and the second solenoid valve 211 is opened, the air outlet end 202 and the first hard tube 206 are in a connected state. 204 is in a blocked state, the air intake end 203 and the second hard tube 206 are in a blocked state, and the air outlet end 202, the first connecting tube 208, the second air tube 207 and the second air bag 108 deep in the vagina are in a connected state, the air intake end 203, the second connecting tube 209, the first air tube 205 and the first air bag 105 are in a connected state, so by alternately controlling the opening and closing of the first solenoid valve 210 and the second solenoid valve 211, the air pump 201 can alternately extract the air in the first air bag 105 and the second air bag 108 through the air intake end 203 and alternately send the air into the second air bag 108 and the first air bag 105 in the corresponding state. When the first air bag 105 is injected with air and expands, it will cling to the inner wall of the vagina to form a solid state. The purpose of fixing the cylinder 102 in the vagina is achieved. Similarly, when the second airbag 108 is injected with air and expands, the purpose of fixing the piston rod 103 inside the vagina is achieved. When the first airbag 105 and the second airbag 108 are in a negative pressure contraction state, the volume is small, which is convenient for moving inside the vagina. In this process, the cylinder 102 is started to drive the piston rod 103 to cooperate and expand. When the annular water bag 304 on the surface of the piston rod 103 needs to move deep into the vagina, the second airbag 108 is controlled to expand and the first airbag 105 is contracted. The cylinder 102 controls the piston rod 103 to contract. At this time, the first airbag 105 will move toward the second airbag 108 in a fixed state. Then the first airbag 105 is expanded and fixed, and the second airbag 108 is contracted.After the cylinder 102 controls the piston rod 103 to extend, it pushes the second airbag 108 deep into the vagina. This reciprocating process can make the annular water bag 304 on the surface of the piston rod 103 move deep into the vagina. Conversely, the first airbag 105 expands first, and the second airbag 108 contracts later. Finally, the cylinder 102 controls the piston rod 103 to contract, which can make the second airbag 108 continuously move toward the outside of the vagina, thereby achieving the purpose of driving the annular water bag 304 to move outward. Under the cooperation of each other, the annular water bag 304 can be driven to move freely inside the vagina by the alternate expansion and contraction of the first airbag 105 and the second airbag 108, and the movement is in a peristaltic state, which will not cause abrasions to the vaginal wall mucosa, and is conducive to the recovery of the mother. During the process of inflating the first airbag 105, the air pump 201 cooperates with the first rigid tube 204, the first air pipe 205, the second rigid tube 206, the second air pipe 207, the first connecting pipe 208, the second connecting pipe 209, the first solenoid valve 210, and the second solenoid valve 211 to fully utilize the gas in the second airbag 108. Conversely, when inflating the second airbag 108, the gas inside the first airbag 105 is fully utilized, and there is no need to connect it to the outside air through a pipeline. This reduces the number of pipelines and improves practicality. When the present device is used to flush and clean the vagina of a parturient, if disinfectant remains inside the vagina and is difficult to flow out in time, the input end of the diaphragm pump 404 is connected through the three-way proportional valve 405, the first water suction pipe 406, the first connecting pipe 407, the second connecting pipe 410 and the annular shell 408 on the surface of the first airbag 105. Therefore, after the diaphragm pump 404 is started, the inside of the annular shell 408 will be in a low-pressure state, thereby causing the hose head 409 around the annular shell 408 to generate suction. At this time, the distance between the hose head 409 and the inner wall of the vagina is small, and the generated suction can absorb the excess disinfectant in time and discharge it to the outside through the output end of the diaphragm pump 404, thereby avoiding the problem of excessive disinfectant flowing into the deep part of the vagina and being difficult to clean, causing infection, thereby improving the nursing effect of the present device. During the process of absorbing excess disinfectant inside the vagina by starting the diaphragm pump 404, the three-way proportional valve 405 controls the flow rate through the input end of the diaphragm pump 404, so that the diaphragm pump 404 generates two suction forces that act on the first water suction pipe 406 and the second water suction pipe 411 simultaneously, and the suction force generated by the second water suction pipe 411 is larger. At this time, since the second water suction pipe 411 and the plane shell 412 are in a connected state and the plane shell 412 is surrounded by openings 413, the plane shell 412 is placed on the bed outside the vaginal opening of the parturient. The suction force generated by the openings 413 on the surface of the plane shell 412 can absorb the disinfectant that naturally flows out and falls on the bed and then discharge it to a designated location through the output end of the diaphragm pump 404, thereby solving the problem of a large amount of disinfectant remaining on the bed during the cleaning of the parturient's vagina and improving the use effect of the device.
