Description

Technical Field

[0001] The utility model belongs to the technical field of cervical dilators, and in particular relates to an airbag type cervical dilator with a protective function. Background Art

[0002] The female cervix is ​​located at the lower part of the uterus. The length of the cervical canal of an adult female is about 3CM. The center of the cervix is ​​a long fusiform lumen that is slightly flattened from front to back. It is mainly composed of connective tissue and also contains smooth muscle fibers, blood vessels and elastic fibers. During gynecological and obstetric surgeries such as IUD removal, IUD placement, artificial abortion, and curettage, due to the tight cervical opening, a cervical dilator is often needed to dilate the cervical opening to achieve the purpose of the operation. A balloon cervical dilator is a device that physically dilates the cervix. It uses a balloon placed into the cervical canal, which is then inflated to gradually soften and dilate the cervix and promote the opening of the cervical opening. The balloon dilation device dilates the cervical canal by physical methods, promotes the progress of labor, and shortens the labor process. It has a certain promoting effect on increasing the rate of vaginal delivery. However, most of the existing balloon cervical dilators directly insert a balloon into the cervix to dilate the cervix, and leave a balloon on the outside of the cervical opening to dilate the vagina, which is convenient for observing the condition of the cervix. During the process of retaining the balloon, a certain amount of secretion fluid will be produced inside the vagina. If the fluid is not cleaned, as the cervix expands, the balloon will pump up and down along the cervical opening, which may bring a certain amount of secretion fluid into the uterus. During the retention of the cervical dilator, it may cause infection inside the cervix. Utility Model Content

[0009] In order to facilitate the use of this device and improve its practicality:

[0010] As a further improvement of the above technical solution: a check valve is provided at the proximal end of the main pipe and the first branch pipe and located on the inner side of the inflation head, and a one-way valve is provided on the second branch pipe.

[0011] The beneficial effects of this improvement are as follows: a check valve is arranged on the main pipe and the first branch pipe, which can facilitate the inflation of the cervical air bag and the vaginal air bag to dilate the cervix or release the gas in the cervical air bag and the vaginal air bag to facilitate the removal of the device from the patient's body; a one-way valve is arranged on the second branch pipe, which can prevent the backflow of liquid and cause cervical infection when absorbing the liquid in the vagina, thereby improving the practicality of the device.

[0012] To reduce your chances of getting a cervical infection:

[0013] As a further improvement of the above technical solution: the number of the liquid pipetting heads arranged on the annular tube is several, and the several liquid pipetting heads are evenly distributed on the side wall of the annular tube.

[0014] The beneficial effect of this improvement is that a plurality of liquid suction heads are arranged on the annular tube, which can increase the speed of liquid absorption and expand the range of liquid absorption, thereby reducing the probability of cervical infection.

[0015] In order to protect the cervix and avoid cervical infection when using a cervical dilator:

[0016] As a further improvement of the above technical solution: the main pipe is connected to the cervical airbag, the first branch pipe is connected to the vaginal airbag, the second branch pipe is connected to the annular pipe, and the main pipe, the first branch pipe and the second branch pipe do not interfere with each other.

[0017] The beneficial effects of this improvement are: the main tube, the first branch tube and the second branch tube do not affect each other, and each performs its own function. When in use, the cervical air bag and the vaginal air bag can be inflated successively to prevent the cervical air bag from slipping out of the cervix. After insertion, the second branch tube can also extract the secretory fluid in the vagina to prevent it from flowing back into the cervix when the cervix dilates and causing cervical infection.
