AI Technical Summary
The balloon of existing catheters has a small contact area with the bladder wall, which can easily compress the bladder and cause pain or urinary tract infection.
The catheter is designed with multiple drainage holes and a double-ring balloon structure. The drainage holes are used to drain urethral fluid, and the double-ring balloon forms a frustum shape that is larger at the front and smaller at the back to reduce bladder pressure. Combined with a one-way valve and quick-release components, it improves assembly efficiency and sealing.
It reduces pressure on the bladder wall, lowers the risk of urethral injury and infection, and improves assembly efficiency and sealing.
