An air hole connected to the flushing chamber 1 is opened at the upper end of the box body 18. A liquid outlet pipe 3 connected to the flushing chamber 1 is fixed on the box body 18. A liquid return pipe 4 connected to the waste liquid chamber 2 is fixed on the box body 18. The liquid return pipe 4 and the liquid outlet pipe 3 are both in an inverted L shape as a whole.

[0023] The box body 18 is provided with a filling port connected to the flushing chamber 1, and a cap is threadedly sealed on the filling port. The box body 18 is provided with a discharge pipe connected to the waste liquid chamber 2, and a valve is installed on the discharge pipe.

[0024] The liquid guide assembly is connected to the housing 18, and the liquid guide assembly can squeeze out the flushing liquid in the flushing cavity 1 through the liquid outlet tube 3 and flush the uterine cavity. The flushing liquid forms waste liquid after flushing the uterine cavity. The liquid guide assembly can collect the waste liquid in the uterine cavity into the waste liquid cavity 2 through the liquid return tube 4.

[0025] The liquid guide assembly includes a first branch pipe 13 connected to the vertical portion of the liquid outlet pipe 3, the first branch pipe 13 is fixedly connected to the box 18 and connected to the flushing chamber 1, and one end of the first branch pipe 13 away from the liquid outlet pipe 3 is close to the inner lower end of the flushing chamber 1. A third one-way valve 11 is installed on the first branch pipe 13, and the third one-way valve 11 only allows the flushing liquid in the flushing chamber 1 to enter the liquid outlet pipe 3 through the first branch pipe 13.

[0026] A fourth one-way valve 14 is installed on the liquid outlet pipe 3 above the connection between the first branch pipe 13 and the liquid outlet pipe 3 . The fourth one-way valve 14 only allows the liquid or gas in the liquid outlet pipe 3 to be discharged through the upper end of the liquid outlet pipe 3 .

[0027] The straight portion of the liquid return pipe 4 is connected to the waste liquid chamber 2. Specifically, the straight portion of the liquid return pipe 4 is provided with adjacent concave portions and convex portions, and the lower end of the concave portion of the liquid return pipe 4 is connected to the waste liquid chamber 2 through the second branch pipe 16.

[0028] A fifth one-way valve 15 is installed on the vertical portion of the liquid return pipe 4 , and the fifth one-way valve 15 only allows gas or liquid to enter the liquid return pipe 4 through the upper end of the liquid return pipe 4 .

[0029] The rubber bag 10 is also provided with a spherical shape. The rubber bag 10 is elastic. A cushion 12 is fixed inside the rubber bag 10. The cushion 12 divides the rubber bag 10 into an independent outlet cavity 19 and a return cavity 20. The outlet cavity 19 is connected to the lower end of the liquid outlet pipe 3, and the return cavity 20 is connected to the lower end of the liquid return pipe 4. A sixth one-way valve 17 connected to the return cavity 20 is fixed at the lower end of the rubber bag 10. The sixth one-way valve 17 only allows the gas in the return cavity 20 to be discharged to the outside of the rubber bag 10 through the sixth one-way valve 17.

[0030] When flushing the patient's uterine cavity, the upper ends of the liquid outlet tube 3 and the liquid return tube 4 are inserted into the patient's uterine cavity. When the rubber bag 10 is pressed, the space in the outlet cavity 19 and the return cavity 20 is reduced. Since the third one-way valve 11 only allows the flushing liquid in the flushing cavity 1 to enter the liquid outlet tube 3 through the first branch pipe 13, and the fourth one-way valve 14 only allows the liquid or gas in the liquid outlet tube 3 to be discharged through the upper end of the liquid outlet tube 3. When the rubber bag 10 is pressed, the third one-way valve 11 is closed and the fourth one-way valve 14 is opened, and the gas in the outlet cavity 19 is discharged through the liquid outlet tube 3.

[0031] After the rubber bag 10 is released, the rubber bag 10 is restored under the elastic force of the rubber bag 10. During the restoration process of the rubber bag 10, the space of the outlet cavity 19 gradually increases. During the gradual increase of the space of the outlet cavity 19, the fourth one-way valve 14 is closed, the third one-way valve 11 is opened, and the flushing liquid in the flushing cavity 1 can enter the outlet pipe 3 through the first branch pipe 13, and the flushing liquid entering the outlet pipe 3 can enter the outlet cavity 19. When the flushing liquid is stored in both the outlet cavity 19 and the outlet pipe 3, the flushing liquid is discharged from the upper end of the outlet pipe 3 after the rubber bag 10 is pressed, and the patient's uterine cavity can be flushed. During the squeezing and restoration process of the rubber bag 10, the flushing liquid in the flushing cavity 1 is continuously drawn out and discharged through the upper end of the outlet pipe 3.

[0032] When the rubber bag 10 is pressed, the fifth one-way valve 15 only allows gas or liquid to enter the liquid return pipe 4 through the upper end of the liquid return pipe 4, and the sixth one-way valve 17 only allows the gas in the return chamber 20 to be discharged to the outside of the rubber bag 10 through the sixth one-way valve 17. Therefore, when the rubber bag 10 is pressed, the sixth one-way valve 17 is opened, the fifth one-way valve 15 is closed, and the gas in the return chamber 20 is discharged through the sixth one-way valve 17.

[0033] When the rubber bag 10 is released, it is restored under the elastic force of the rubber bag 10, and the space of the return cavity 20 gradually increases during the restoration of the rubber bag 10. At the same time, the fifth one-way valve 15 is opened, the sixth one-way valve 17 is closed, and the waste liquid in the patient's uterine cavity enters the return liquid pipe 4 through the upper end of the return liquid pipe 4.

[0034] When the waste liquid flows through the lower convex portion of the liquid return pipe 4 , the waste liquid in the liquid return pipe 4 can enter the waste liquid chamber 2 through the second branch pipe 16 .

[0035] In this embodiment, during the process of pressing and releasing the rubber bag 10, the flushing liquid can flush the patient's uterine cavity. At the same time, the waste liquid in the uterine cavity can be collected.

[0036] Embodiment 2:

[0037] The other features of this embodiment are the same as those of the embodiment, except that:

[0038] Reference Figure 4-Figure 5 As shown, the liquid guiding assembly includes a second piston 8 connected in a sliding and sealing manner in the waste liquid chamber 2 and a first piston 7 connected in a sliding and sealing manner in the flushing chamber 1 .

[0039] A first one-way valve 5 is fixed on the box body 18 above the first piston 7 . The first one-way valve 5 is connected to the flushing chamber 1 . The first one-way valve 5 only allows the gas outside the box body 18 to enter the flushing chamber 1 .

[0040] A second one-way valve 6 is fixed on the box body 18 above the second piston 8 . The second one-way valve 6 is connected to the waste liquid chamber 2 . The second one-way valve 6 only allows the gas in the waste liquid chamber 2 to be discharged to the outside of the box body 18 .

[0041] Air pipes 21 are fixed to the box body 18 below the first piston 7 and the second piston 8 . The two air pipes 21 are connected to the flushing chamber 1 below the first piston 7 and the waste liquid chamber 2 below the second piston 8 , respectively.

[0042] A seventh one-way valve 31 is installed on the liquid outlet pipe 3 , and the seventh one-way valve 31 only allows the flushing liquid in the flushing cavity 1 to be discharged through the upper end of the liquid outlet pipe 3 .

[0043] An eighth one-way valve 41 is installed on the liquid return pipe 4 , and the eighth one-way valve 41 only allows waste liquid in the uterine cavity to enter the liquid return pipe 4 through the upper end of the liquid return pipe 4 .

[0044] A vertical push rod 9 is fixed to the lower end of the first piston 7 and the second piston 8. The push rod 9 passes through the bottom plate of the box body 18. The push rod 9 is slidably connected to the bottom plate of the box body 18. The lower ends of the two push rods 9 are fixedly connected by a connecting rod 22.

[0045] In this embodiment, when it is necessary to flush the patient's uterine cavity, the first piston 7 and the second piston 8 are driven by the connecting rod 22 and the push rod 9 to move upward in the flushing cavity 1 and the waste liquid cavity 2. Since the first one-way valve 5 only allows the gas outside the box 18 to enter the flushing cavity 1, the second one-way valve 6 only allows the gas in the waste liquid cavity 2 to be discharged to the outside of the box 18, the seventh one-way valve 31 only allows the flushing liquid in the flushing cavity 1 to be discharged through the upper end of the liquid outlet pipe 3, and the eighth one-way valve 41 only allows the waste liquid in the uterine cavity to enter the liquid return pipe 4 through the upper end of the liquid return pipe 4. During the upward movement of the first piston 7 and the second piston 8, the seventh one-way valve 31 is opened, the first one-way valve 5 is closed, the second one-way valve 6 is opened, and the eighth one-way valve is closed. The flushing liquid above the first piston 7 can be discharged through the liquid outlet pipe 3 and flush the patient's uterine cavity. In this process, the flushing liquid will not be discharged through the first one-way valve 5.

[0046] During the upward movement of the first piston 7 and the second piston 8 , the air in the waste liquid chamber 2 above the second piston 8 is discharged through the second one-way valve 6 .

[0047] When it is necessary to collect the waste liquid in the uterine cavity, the first piston 7 and the second piston 8 are moved downward. During the downward movement of the first piston 7 and the second piston 8, the second one-way valve 6 and the seventh one-way valve 31 are blocked, and the eighth one-way valve 41 and the first one-way valve 5 are opened, so that the waste liquid in the uterine cavity can enter the waste liquid chamber 2 through the return pipe 4. During the downward movement of the first piston 7 and the second piston 8, the air outside the box 18 can enter the flushing chamber 1 through the first one-way valve 5 to compensate the pressure of the flushing chamber 1.
