Through setting up joint body 18 can be when cervix therapentic equipment is in not using state, fold and deposit rubber tube 21.

For ease of understanding, the operation of the cervical treatment apparatus of the present application will be described.

As shown in fig. 2, the valve 17 of the second balloon 9 is first closed, and then the second balloon 9 is continuously pressed to continue injecting air into the second chamber 3b until the piston 2 moves to its extreme position to the left. The first end 1a of the administration catheter 1 is inserted into the liquid medicine bottle, and then the valve 17 of the second balloon 9 is opened to connect the second cavity 3b with the atmosphere, at this time, the piston 2 will move to the right under the action of the compression spring 11, so that the liquid medicine in the liquid medicine bottle is sucked into the first cavity 3 a. Thus, the filling of the liquid medicine is completed.

The valve 17 of the first balloon 6 is opened to flatten the elastomer 4, and then both the administration catheter 1 and the elastomer 4 are inserted into the vagina of the patient. The valve 17 of the first balloon 6 is closed, and the first balloon 6 is continuously pressed, so that the elastic body 4 is expanded, and the administration catheter 1 is fixed. At this point, the fixation of the administration catheter 1 in the vagina is completed.

The medical fluid in the first cavity 3a can be injected into the vagina of the patient from the first end 1a by closing the valve 17 of the second balloon 9 and then continuously pressing the second balloon 9. At this point, the injection of the liquid medicine is completed.

When the valve 17 of the first balloon 6 is opened, the elastic body 4 will return to a flat shape due to its own elasticity, thereby facilitating the removal of the administration catheter 1. Subsequently, after the cervical therapeutic apparatus is sterilized, the rubber hose 21 can be inserted into the engaging body 18 for fixing.
