The invention will be further described with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1, the medical catheter according to the present embodiment comprises a hose body 1, the hose body 1 has an open connection end 2 and a closed introduction end 3, the hose body 1 is provided with a urethral catheterization hole 4 close to the introduction end 3, the urethral catheterization hole 4 communicates the outside with the inside of the hose body 1, the hose body 1 is provided with a branch pipe body 5 close to the connecting end 2, a first air bag 6 surrounding the branch pipe body 5 is arranged in the branch pipe body 5, a second air bag 7 surrounding the hose body 1 and close to the leading-in end 3 is arranged in the hose body 1, a first air path 8 for communicating the second air bag 7 with the first air bag 6 is connected between the second air bag 7 and the first air bag, the branch pipe main body 5 is provided with a second air path 9 communicated with the first air path 8, the second air path 9 is connected with a one-way valve 10 communicated with the outside in series, and the one-way valve 10 is communicated from the outside to the direction of the second air path 9.

Wherein, the setting of link 2 for the installation urine bag carries out the collection to the urine.

The one-way valve 10 has a better gas sealing effect, is not easy to leak gas, and is easy to retain gas in the air bag and the gas circuit after long-time use; if the gas needs to be discharged, the check valve 10 is manually opened, and the outside is communicated with the second gas path 9.

In the present embodiment, after the introduction end 3 of the tube body 1 is inserted into the bladder, the first air passage 8 and the second air passage 9 are supplied with air through the check valve 10, so that the first air bag 6 and the second air bag 7 are inflated to fix the introduction end 3 to the bladder and prevent the air from escaping, and the second air bag 7 outside the body is communicated with the first air bag 6 inside the bladder, so that the air volume of the first air bag 6 remaining in the bladder can be observed in real time, and the air can be appropriately supplied to prevent the air from escaping.
