The gynecological diseases are usually accompanied by symptoms such as increased vaginal secretion, vaginal inflammation and the like, taking cervical cancer as an example, the cervical cancer is a common gynecological malignant tumor, the treatment modes mainly comprise operation treatment, radiotherapy and chemotherapy, and for middle and late cervical cancer patients in radiotherapy, chemotherapy and near-distance afterloading treatment, after the radiotherapy dosage reaches a certain range, the mucosa of the vaginal wall and the endoconch of the cervical canal of the patient are fibrillated due to the radioactive inflammation, so that vaginal stenosis and adhesion are formed, the drainage of the uterine cavity is not smooth, and the pyorrhea and effusion of the uterine cavity are caused.

In order to solve the problems, a means of washing the vagina is generally adopted to relieve symptoms of congestion, edema and the like of vagina mucosa, simultaneously, the vagina mucosa washing device also has the effects of preventing vagina adhesion and stenosis, and can also timely remove tumor necrotic tissues after radiotherapy and chemotherapy and increase the sensitivity of the radiotherapy and chemotherapy. After the radiotherapy, white pseudomembranous covering tumor mainly comprising fiber exudation and white blood cells is formed on the cervical and vaginal mucosa, and generally disappears after about 3 months of the radiotherapy, and at the stage, if the vaginal irrigation is not continuously matched, the symptoms of adhesive vaginitis and/or vaginal stenosis can be caused or aggravated because vaginal secretion is increased and necrotic cast cannot be completely discharged out of the body. Therefore, vaginal irrigation is required during all late hospitalizations for cervical cancer, except for heavy bleeding and menstrual periods.

For patients with vaginal adhesion, currently, hospitals generally adopt vaginal dilators to dilate the vagina and then flush the vagina, most of the vaginal dilators are of duckbill structures, and the head of the vaginal dilator needs to be opened after entering the vagina, so that the width of the head of the vaginal dilator stretching into the vagina is still larger, the size of the vaginal dilator is still larger for patients with severe vaginal adhesion, and pain of the patients can be increased undoubtedly. Moreover, after the vagina is dilated, the vagina dilator still needs an additional flushing structure to send flushing fluid into the vagina while keeping the dilated state, so that another person needs to operate the vagina dilator, and a part of conservative patients cannot accept the operation, so that the part of patients cannot be cleaned, and the symptoms of adhesive vaginitis and/or vaginal stenosis are aggravated.

The specific implementation process of this embodiment is as follows:

initially, the elastic air bag 13 is located in the limiting groove 12, and the flushing pipe 36 and the connecting pipe 22 are both separated from the liquid inlet 34. When the vagina adhesion is serious, a patient slides the piston 31 to the lower end of the pressurizing cylinder 3 manually, then the flushing liquid is added into the pressurizing cavity 32 from the liquid inlet 34, then the right end of the connecting pipe 22 is connected with the liquid inlet 34, and then the flushing head 1 is slid into the vagina. The push rod 33 is pushed upwards to slide the piston 31 upwards, so that the flushing liquid is pushed into the negative pressure groove 11, the pressure in the negative pressure groove 11 is increased, the elastic piece 14 is expanded outwards, and the inner wall of the vagina is slightly expanded outwards. At this time, the irrigation passage 15 is opened, and the irrigation liquid flows out from the irrigation passage 15 to irrigate the inner wall of the vagina.

When the vaginal pressure sensitive adhesive is used by a patient with a slight vaginal adhesion, the irrigation tube 36 is connected to the fluid inlet 34 after the irrigation fluid is introduced into the pressurizing chamber 32.

When the piston 31 is pushed to slide, the piston 31 enters the flushing chamber to further increase the pressure in the elastic layer 4, so that the elastic layer 4 expands slightly further outwards, and a gap is formed between the elastic layer 4 and the elastic air bag 13. The washing liquid finally flows out from the washing hole 41 to directly wash the inner wall of the vagina. After the flushing is finished, the flushing head 1 is slid outwards.
