[0028] Please see Figures 1-4This utility model provides a backflow prevention urostomy device, including a urostomy bag 100, and the inside of the urostomy bag 100 is equipped with a conical guide plate 150, a flexible baffle 160 and a float plate 180 for preventing backflow.

[0029] The urinary ostomy bag 100 has an opening 110 at its front end. Inside the opening 110 is a fixation patch 120 for fixing the urinary ostomy bag 100 to the patient's wound. When installing the fixation patch 120, the installation site is first cleaned and dried, and then the fixation patch 120 is fixed with glue.

[0030] The fixing patch 120 has limiting loops 121 fixedly installed at both ends. Straps can be attached to the limiting loops 121 to secure the urostomy bag 100 to the patient's waist, preventing it from falling off due to strenuous exercise. A urine discharge tube 130 for draining urine is fixedly installed at the lower end of the urostomy bag 100. A limiting collar 131 for limiting the limiting band 141 is installed in the middle of the urine discharge tube 130. A sealing plug 140 for sealing the urine discharge tube 130 is installed at one end of the urine discharge tube 130. The limiting band 141 is a flexible connecting band, facilitating the sealing plug 140 to seal one end of the urine discharge tube 130.

[0031] The upper end of the inner cavity of the urostomy bag 100 is equipped with a conical guide plate 150 and a flexible baffle 160 for guiding urine flow. The conical guide plate 150 and the flexible baffle 160 divide the inner cavity of the urostomy bag 100 into a drainage chamber 10 and a urine storage chamber 20. Multiple first connecting blocks 161 are fixedly installed on the outer walls of the left and right sides of the flexible baffle 160. When the left and right sides of the flexible baffle 160 are close together, the first connecting blocks 161 on the left and right sides of the flexible baffle 160 are equidistantly distributed in a crisscross pattern, which facilitates pressing the lower end of the flexible baffle 160 and preventing urine backflow.

[0032] The urine storage chamber 20 is equipped with a float plate 180 for use with the flexible baffle 160 to prevent urine backflow. A second connecting block 181 is fixedly installed at one end of the float plate 180, and a limit slider 182 is fixedly installed at one end of the second connecting block 181.

[0033] The upper end of the urine storage chamber 20 is equipped with a limiting block 170 for limiting the float 180. A first limiting groove 171 for limiting the second connecting block 181 is provided on one side of the limiting block 170, and a second limiting groove 172 for limiting the limiting slider 182 is provided on one side of the first limiting groove 171.

[0034] When the patient lies on their side, the urine pushes the float 180, causing the float 180 to slide from the lower end of the second limiting groove 172 to the upper end of the second limiting groove 172. The end of the float 180 near the flexible baffle 160 pushes the first connecting block 161, causing the first connecting blocks 161 on both sides of the flexible baffle 160 to cause the left and right sides of the flexible baffle 160 to stick together, thereby preventing urine backflow and avoiding urinary tract infection in the patient.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
