The sealing cover 7 is movably set on one side of the connecting frame 6 through a rotating shaft. The sealing cover 7 plays a sealing role. A groove 8 is opened at the other side of the bottom of the ring block 4. The groove 8 is used to set the corresponding components. A connecting rod 9 is set inside the groove 8. The connecting rod 9 is used to connect the sealing cover 7. The bottom of the connecting rod 9 extends to the outside of the groove 8 and is movably connected to the sealing cover 7 through a rotating shaft. A fixed plate 10 is movably set on the top of the connecting rod 9 through a rotating shaft. The fixed plate 10 is used to set a reset spring 11. A reset spring 11 is set when the top of the fixed plate 10 is fixed at both sides. The reset spring 11 can drive the sealing cover 7 to reset.

[0023] Furthermore, the bottom of the urinary bag 1 is connected to an external discharge pipe 12, wherein the external discharge pipe 12 is convenient for the user to discharge urine to the outside.

[0024] Furthermore, a buckle 13 is fixedly provided on the front surface of the stoma connection bag 2, wherein the buckle 13 is used to connect with the stoma, and an adhesive tape is provided on the front surface of the buckle 13 to facilitate adhesion to the skin.

[0025] Furthermore, the bottom of the anti-backflow tube 3 is connected to a connecting tube 14 , and the bottom of the connecting tube 14 is connected to the urinary bag 1 , wherein the connecting tube 14 serves to connect the anti-backflow tube 3 with the urinary bag 1 .

[0026] Furthermore, the through groove 5 and the ring block 4 are of an integrated design, wherein the through groove 5 is provided on the ring block 4 and adopts an upper and lower opening design to facilitate the circulation of urine.

[0027] Furthermore, the top end of the sealing cover 7 contacts with the bottom end of the ring block 4 , wherein the top end of the sealing cover 7 is in close contact with the bottom end of the ring block 4 in a closed state, thereby playing a sealing role.

[0030] Working principle: When using the device, the user uses the sticky tape on the ring buckle 13 to stick the device to the stoma. When urine passes through the ring block 4 and the stoma connecting bag 2 into the anti-backflow tube 3, the power generated by the falling urine will press the sealing cover 7 set at the lower end of the through groove 5 to tilt, thereby opening a gap at the bottom of the through groove 5 to allow urine to flow downward. When the sealing cover 7 is tilted, it will drive the connecting rod 9 to move, and the movement of the connecting rod 9 will drive the fixed plate 10 to pull the reset spring 11 to stretch. When the urine is discharged, the reset spring 11 will reset due to the loss of the power generated by the falling urine, thereby driving the fixed plate 10 to move, and the movement of the fixed plate 10 will drive the connecting rod 9 to pull the sealing cover 7 to move, so that the sealing cover 7 is parallel to the ring block 4 and in close contact with the bottom of the ring block 4, and the force applied by the reset spring 11 is used to seal, so that the sealing cover 7 will not shake.

[0031] According to the above working process, we can know:

[0032] The anti-backflow urinary stoma device adopts a mechanical pressure sealing design by providing a sealing cover 7, a connecting frame 6, a reset spring 11 and a connecting rod 9, so that the device is tightly sealed and will not be loosened, which greatly improves the sealing effect of the device and avoids urine leakage and backflow, brings convenience to the user, improves the practicality of the device, and meets the user's usage needs.
