Description

Vagina adhesion preventing vaginal dilator

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a vagina-dilating device for preventing vaginal adhesion.

Background

Cervical cancer is a global critical public health issue and is one of the common malignant tumors that seriously threaten the global female health. The cervical cancer treatment effect is very optimistic, and the main treatment way is chemoradiotherapy and surgery. Although cervical cancer is a good treatment, a series of complications affecting quality of life are associated with the later rehabilitation process, one of which is severe vaginal adhesion. After vaginal adhesion, the cervix is difficult to see in gynecological examination, and a certain difficulty is brought to tumor recheck. In addition, the life of the couple is affected. Once vaginal adhesions occur, there is currently no good therapeutic measure. Because the vagina is affected by radiotherapy, the vaginal leakage is easily caused by forced separation of vaginal adhesion in operation, and larger complications occur.

The main method is to keep the vagina rinsed for more than one year. The long-term flushing also has the risk of breaking the normal flora of the vagina and inducing vaginitis.

In addition, when the vagina is irrigated, the vagina is only expanded once when the cleaner is inserted, the vagina is lack of continuous reciprocating expansion, and the elasticity of the vagina is difficult to recover. If the vagina is to be expanded reciprocally, the cleaner needs to be continuously taken out and plugged in, and the vaginal pain and infection are easily caused in the taking out and plugging in process. Therefore, the prior art has the problem that the vagina is difficult to continuously and repeatedly dilate.

Detailed Description

The technical scheme of the utility model is clearly and completely described by a specific implementation mode of the embodiment of the utility model with the aid of the attached drawings.

Referring to fig. 1, the utility model relates to an anti-vaginal adhesion vaginal dilator, which comprises a push rod 2 and an air bag 1, wherein the air bag 1 is fixedly connected with the rod wall of the push rod 2. The push rod 2 is internally provided with a vent hole 3, and the vent hole 3 is communicated with the air bag 1. The air bag 1 is inflated by injecting air into the air bag 1 through the vent hole 3, and the air bag 1 is contracted by exhausting air through the vent hole 3. After the air bag 1 is plugged into the vagina, the vagina is expanded by inflating the air bag 1, and the vagina is expanded when the air bag 1 is inflated.

As shown in fig. 2, the device further comprises an inflation pipeline and an inflation plunger, wherein two ends of the inflation pipeline are respectively connected with the inflation plunger and the inflation hole. The inflation plunger injects gas into the balloon 1 through the inflation tube, thereby expanding the balloon 1. The inflation plunger comprises a cylinder 8, a piston 7 and a cam 9, wherein a motor 11 is fixed on the cylinder 8 through a fastener, the cam 9 is in transmission connection with an output shaft of the motor 11, the cam 9 is rotatably connected with the cylinder 8, a rotating shaft 10 of the cam 9 is perpendicular to the axis of the cylinder 8, the piston 7 is slidably connected with the inner wall of the cylinder 8, and the cam 9 abuts against the piston 7. The inflation pipe is connected with the cylinder 8, and when the motor 11 drives the cam 9 to rotate, the cam 9 pushes the piston 7 to move, so that the gas in the cylinder 8 is injected into the air bag 1 through the ventilation pipe 5.

The end of the vent pipe 5 is inserted into one end of the vent hole 3 and connected to the vent hole 3 by adhesion, thereby inputting the gas from the vent hole 3 into the airbag 1. The other end of the vent hole 3 is arranged in the air bag 1.

The cylinder 8 is also internally provided with a spring 6, one end of the spring 6 is abutted against the cylinder 8, and the other end is abutted against the piston 7. The spring 6 is in a compressed state, and the elastic force of the spring 6 keeps the piston 7 against the cam 9. Therefore, when the cam 9 rotates, the piston 7 continuously reciprocates, so that the air is intermittently injected into and exhausted from the air bag 1, and the air bag 1 is intermittently inflated and deflated, thereby continuously expanding the vagina.

After the motor 11 stops working, the elastic force of the spring 6 pushes the piston 7 to move, so that the air bag 1 is contracted, and the air bag 1 is taken out conveniently.

The shape of the air bag 1 is elliptic, and the elliptic shape is convenient for inserting into vagina. One end of the push rod 2 penetrates through the air bag 1 and is fixedly connected with the air bag 1 in a viscose manner. The other end of the push rod 2 is provided with a gripping part 4, the gripping part 4 is of a spherical structure or a disc-shaped structure, and the gripping part 4 is used for increasing the gripping area of the palm, so that the gripping of the push rod 2 is more stable. And the pressure that the gripping portion 4 can also reduce when the palm promotes push rod 2 receives, avoid promoting the too big pressure and cause the palm pain when push rod 2.

In another embodiment, the two ends of the ventilation pipe 5 are respectively connected with the air bag 1 and the inflation plunger. In this case, the vent hole 3 is not provided in the push rod 2. When the push rod 2 pushes the air bag 1 into the vagina, the end of the air inflation pipeline connected with the air bag 1 also follows the air bag 1 to enter the vagina. The simultaneous entry of the duct and the push rod 2 into the vagina may cause a stronger uncomfortable feeling to the vagina than the structure provided with the ventilation hole 3.

The cam 9 is connected with the cylinder 8 through a rotating shaft 10, and the rotating shaft 10 is connected with an output shaft of the motor 11 through a coupler. The rotating shaft 10 is rotatably connected with the cylinder 8, the rotating shaft 10 is provided with a screw hole, and the rotating shaft 10 is fixedly connected with the cam 9 through a locking screw 12.

As shown in fig. 3, the rotating shaft 10 is provided with a plurality of cams 9, and the plurality of cams 9 are different in size and different in pushing distance to the piston 7. Only one cam 9 on the rotating shaft 10 is fixed by a locking screw 12, and the other cams 9 can rotate relative to the rotating shaft 10 when the rotating shaft 10 rotates. For example, the cam 9 is clearance-fitted with the rotation shaft 10 so that the cam 9 can rotate with respect to the rotation shaft 10. Therefore, only the cam 9 fixed by the locking screw 12 can exert a pushing action on the piston 7. The movement distance of the piston 7 can be changed by replacing the cam 9 fixed by the locking screw 12, and the expansion size of the airbag 1 can be changed. The vaginal dimensions of different users are different, and the inflation dimensions of the air bag 1 are changed by changing the mode of the cam 9, so that the device is suitable for different users. This arrangement can increase adaptability to different users.
