DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0023] like Figure 1 , as shown in FIG6 , the utility model provides a ureteral and renal pelvic flushing device, comprising a first flushing liquid container 1 and a second flushing liquid container 2. The first flushing liquid container 1 is connected with a liquid outlet pipe 3, and a first one-way valve 6 is arranged on the liquid outlet pipe 3; the second flushing liquid container 2 is connected with a liquid inlet pipe 5, and a second one-way valve 7 is arranged on the liquid inlet pipe 5. The liquid outlet pipe 3 and the liquid inlet pipe 5 are connected through a three-way pipe 8, and a syringe 9 is connected to the third pipe opening of the three-way pipe 8. The flow direction of the first one-way valve 6 is from the first flushing liquid container 1 to the three-way pipe 8, and the flow direction of the second one-way valve 7 is from the three-way pipe 8 to the second flushing liquid container 2. The second flushing liquid container 2 is also connected with a device connecting pipe 10, and a flow regulating valve 11 is arranged on the device connecting pipe 10.

[0024] When in use, the piston of the syringe 9 is pulled, and under the action of atmospheric pressure, the flushing liquid in the first flushing liquid container 1 flows into the syringe 9 through the first one-way valve 6, and then the piston of the syringe 9 is pushed, and the flushing liquid in the syringe 9 enters the second flushing liquid container 2 through the second one-way valve 7; repeat the above process to make a certain amount of flushing liquid in the second flushing liquid container 2, and then connect the equipment connecting tube 10 to the medical instrument ureterendoscope to flush the patient's renal pelvis.

[0025] A pressure flow meter may be provided between the second flushing liquid container 2 and the flow regulating valve 11 to facilitate the operator of the injector 9 to grasp the pressure in the second flushing liquid container 2 in real time and adjust the pushing and pulling speed of the injector 9 in time.

[0026] like Figure 2-5 As shown, the one-way valve 14 includes a one-way valve housing 15, a one-way valve frame 22, a one-way valve core body 18, a spring 4, a first sealing ring 24 and a second sealing ring 25; the first sealing ring 24 is installed in the first slot 17 on the one-way valve housing 15, the one-way valve housing 15 is connected to the one-way valve frame 22, the one-way valve core body 18 is connected to the one-way valve frame guide hole 23 on the one-way valve frame 22 through the one-way valve core body guide column 19, the second sealing ring 25 is installed on the second slot 21 on the one-way valve core body 18, the one-way valve core body 18 is also provided with a steady flow hole 20 at one end close to the water inlet 16, the spring 4 is installed between the one-way valve core body 18 and the one-way valve frame 22, and the spring 4 passes through the one-way valve core body guide column 19.

[0027] The flushing liquid enters the one-way valve sleeve 15 through the first connecting sleeve 12, and the flushing liquid pressure acts on the one-way valve core body 18, causing the one-way valve core body 18 to move along the flow direction, compressing the spring 4, and separating the matching relationship between the one-way valve core body 18 and the one-way valve sleeve 15, so that the flushing liquid enters the space where the spring 4 is located, and then the flushing liquid enters the second connecting sleeve 13 through several water outlets of the one-way valve frame 22; on the contrary, if the flushing liquid enters the space where the spring 4 is located from the water outlet of the second connecting sleeve 13, due to the close matching between the one-way valve core body 18 and the one-way valve sleeve 15, the flushing liquid cannot enter the first connecting sleeve 12.

[0028] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0029] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
