The first embodiment is as follows:

referring to fig. 1 to 3, a pressure-regulated vaginal dilation flushing rod includes a flushing core tube 10, an expansion sleeve 20 and a connector 30.

The expansion sleeve is an elastic expansion sleeve made of a silica gel material, in order to enable the front end of the expansion sleeve to generate a large expansion amount during inflation, the wall thickness t1 of the front end of the expansion sleeve is smaller than the wall thickness t2 of the rear end of the expansion sleeve, and the wall thickness of the expansion sleeve is gradually increased from the front end to the rear end.

The expansion sleeve is sleeved on the washing core pipe, and the front end of the washing core pipe is exposed out of the front end of the expansion sleeve. The front end and the rear end of the flushing core pipe are hermetically connected with the expansion sleeve.

The flushing core pipe is provided with an inner hole 11 for circulating flushing liquid, the front end of the flushing core pipe is provided with a group of flushing holes 12, the rear end of the flushing core pipe is provided with a step shaft 16, and the rear end of the expansion sleeve is sleeved on the step shaft 16. The step shaft is provided with six vent holes 13, the vent holes 13 are parallel to the axis of the flushing core pipe and distributed in a surrounding mode, and the vent holes 13 are communicated with the inner cavity of the expansion sleeve and the rear end of the flushing core pipe. The rear end of the flushing core pipe is provided with a mounting stud 14.

The flushing core tube and the expansion sleeve form an integral component.

The connector is provided with a flushing port 31 and an inflation port 32. The flushing port is arranged in the center of the connector, and the inflating port is arranged on the connector in a direction inclined by 45 degrees. The connector is provided with a screw hole 38, the bottom surface of the screw hole 38 is provided with a gas passing ring groove 39, the position of the gas passing ring groove corresponds to the vent hole 13 of the washing core pipe, and the gas charging interface is communicated with the gas passing ring groove 39. The bottom surface of the screw hole is provided with an inner ring seal ring 33 and an outer ring seal ring 34.

The flush core tube and expansion sleeve are mounted as one unit to the connector by mounting studs 14. The air inflation port 32 of the connector is communicated with the inner cavity of the expansion sleeve through the vent hole 13 of the flushing core pipe. The flushing port 31 of the connector is communicated with the inner hole 11 of the flushing core pipe. The inner ring sealing ring 33 realizes the sealing between the flushing interface 31 and the connecting surface of the inner hole 11 of the flushing core pipe, and realizes the sealing isolation between the flushing interface and the inflation interface. The outer ring seal 34 seals the inflation port from the outside, and prevents the gas from leaking out.

As shown in fig. 3, the flushing port 31 of the connector is connected to a flushing line 40, the inflation line is connected to a sealed flushing tank 41 containing a flushing liquid 42, and the flushing tank is provided with a pneumatic line 43 for pressurizing the tank. The inflation interface 31 of the connector is connected with an inflation pipeline 50, and a pressure regulating valve 52 and an exhaust valve 53 are arranged on the inflation pipeline. The irrigation line 40 and inflation line 50 are connected to an inflator 51, which in this embodiment is a hand-pressed inflatable balloon (similar to those used in mercury sphygmomanometers), through a diverter valve 55. The reversing valve 55 is a three-way reversing valve, so that the inflator 51 is respectively communicated with the flushing pipeline 40 or the inflating pipeline 50.

When the flushing operation is performed, the air pump (inflatable balloon) 51 communicates with the flushing line 40, pressurizes air in the flushing tank, and applies pressure to the flushing liquid in the flushing tank, so that the flushing liquid is output through the flushing line 40. When the inflation operation is performed, the air pump 51 is connected to the inflation line 50 to pressurize air in the inflatable sleeve.

In use, the inflation sheath and irrigation core tube assembly is inserted into the vagina to the appropriate depth. When the vagina is washed, the air balloon 51 is pressed by hand to output washing liquid along the washing pipeline, the washing liquid enters the inner hole 11 of the washing core pipe through the washing interface 32 and enters the vagina from the washing hole 12 at the front end of the washing core pipe, and the vagina washing function is realized. When the vagina is dilated, the air balloon 51 is pressed by hand, compressed air enters the air ring groove 39 through the air charging connector 32 and then enters the inner cavity of the expansion sleeve 20 from the six air holes 13 through the air ring groove 39, so that the expansion sleeve is expanded, and the vagina is dilated. For patients with gynecological tumors such as cervical cancer, endometrial cancer, vaginal cancer and the like, the top end of the vagina is a main expansion area, and the front end of the expansion sleeve has a strong expansion effect due to the structure that the wall thickness of the front end of the expansion sleeve is gradually reduced, so that the top end of the vagina has a strong expansion function, and a good vagina rehabilitation effect can be obtained. In different cases, patients need different vaginal dilation degrees, and good effects can be obtained by adopting a targeted vaginal dilation scheme. The inflation pressure of the expansion sleeve can be controlled by the pressure regulating valve 52, so that the expansion amount of the expansion sleeve is controlled, and a proper vaginal dilation effect is obtained. The pressure regulating valve is a valve for opening and discharging air when the inflation pressure reaches a set value, is equivalent to the function of a safety valve, can adjust the set value of the pressure regulating valve, and provides the optimal vaginal dilation effect for patients.

A further vagina expanding method is to adopt a circulating expanding mode (or a pulsating expanding mode) and adopt an exhaust valve 53, when the expansion sleeve reaches the set pressure, the exhaust valve 53 gradually releases gas in the expansion sleeve to enable the expansion sleeve to contract properly, after the expansion sleeve contracts to a certain degree, the expansion sleeve is inflated again to enable the expansion sleeve to reach the set pressure, and the circulation exerts an expanding effect on the vagina. In order to make the air pressure in the expansion sleeve slowly and smoothly drop, the exhaust valve needs to adopt a micro mode, the exhaust valve of the embodiment adopts a needle valve with micro exhaust, and the exhaust volume of the needle valve can be adjusted. If the circulation expansion mode is not needed, the exhaust valve is closed.

To enable the patient to carry out vaginal rehabilitation by oneself and obtain good rehabilitation effect, accurate operation is realized firstly, and convenient operation is realized secondly.

In order to be suitable for different patients, expansion sleeves with different effective lengths L need to be adapted, and according to medical practice, five length specifications of expansion sleeves can be configured, wherein the effective lengths of the expansion sleeves are respectively 40mm, 50mm, 60mm, 70mm and 80 mm.

The setting of the vaginal dilation amount and the dilation length is very important for patients, and each patient needs to set an appropriate dilation amount and dilation length to obtain good vaginal rehabilitation effect. Such work needs to be done by a doctor, but the patient cannot rely entirely on the doctor for vaginal recovery for a long period of time. The invention provides a means for patients to perform vaginal rehabilitation by themselves. The doctor makes a proper vaginal rehabilitation scheme for the patient according to the patient case including measuring the vaginal length after operation or radiotherapy, sets the specification of the expansion sleeve, the pressure of the expansion sleeve, the displacement of the circular expansion and the like, then the patient uses the pressure adjusting vaginal expansion flushing rod of the invention to automatically perform vaginal rehabilitation according to the advice.
