[0020] like Figures 1 to 5 As shown, the utility model provides a new type of urinary catheter, a cannula 2 is fixedly installed on the left side of the catheter 1, an airbag 3 is fixedly installed on the middle part of the cannula 2, an air injection tube 4 is fixedly installed above the airbag 3, a bracket 5 is fixedly installed inside the air injection tube 4, a telescopic rod 6 is fixedly installed on the right side of the bracket 5, a spring 7 is sleeved on the outer side of the telescopic rod 6, a sealing plate 8 is fixedly installed on the side of the spring 7 away from the bracket 5, a limiting plate 9 is fixedly installed inside the air injection tube 4, the interior of the limiting plate 9 is hollow, and the inner diameter value is smaller than the diameter value of the sealing plate 8, a fixing sleeve 10 is sleeved on the side of the air injection tube 4 away from the airbag 3, and an airbag 2 11 is fixedly installed on the side of the fixing sleeve 10 away from the air injection tube 4.

[0021] The main function of the airbag 2 11 is to press the airbag 2 11 to inject air into the airbag 1 3 through the air injection tube 4 after the cannula 2 is inserted into the bladder, thereby expanding the airbag 1 3 and achieving a fixation effect.

[0022] Among them, a connecting block 12 is fixedly installed on the outside of the cannula 2 close to the catheter 1, and a limiting clamping ring 13 is fixedly installed on the outside of the connecting block 12. The limiting clamping ring 13 is located on the right side of the airbag 1 3.

[0023] The main function of the limiting clamp ring 13 is to fix the gas injection pipe 4 to prevent the gas injection pipe 4 from being pulled during normal activities.

[0024] A fixing block 14 is fixedly installed above the conduit 1 , the gas injection pipe 4 is located inside the fixing block 14 , and the fixing block 14 is located on the left side of the fixing sleeve 10 .

[0025] The main function of the fixing block 14 is to fix the side of the air injection tube 4 close to the airbag 2 11 to prevent the air injection tube 4 from shaking back and forth due to the soft material.

[0026] A thread 15 is provided on the side of the catheter 1 away from the cannula 2 , a connecting sleeve 16 is engaged on the right side of the thread 15 , a storage bag 17 is fixedly installed on the right side of the connecting sleeve 16 , and a bandage 18 is fixedly installed on the front side of the storage bag 17 .

[0027] The main function of the bandage 18 is to tie the bandage 18 to the leg after the catheter 1 is installed to prevent the storage bag 17 from shaking and pulling due to its heavy weight, thereby increasing its comfort.

[0028] The sealing plate 8 is located on the left side of the limiting plate 9 , and the telescopic rod 6 and the spring 7 are both located inside the gas injection tube 4 .

[0029] The main function of the telescopic rod 6 and the spring 7 is to always provide elastic force to the telescopic rod 6 so that the sealing plate 8 and the limit plate 9 are fitted together, thereby sealing the inside of the gas injection pipe 4 to prevent gas leakage after gas is injected.

[0030] There are three connecting blocks 12, all of which are located on the right side of the airbag 1 3, and the limiting clamp 13 is in a circular ring shape.

[0031] The main function of the three connecting blocks 12 is to fix the limiting clamp ring 13 on the surface of the cannula 2 to prevent shaking, thereby affecting the normal gas injection of the gas injection tube 4.

[0032] The working principle and use process of this utility model:

[0033] First, insert the cannula 2 into the bladder. Then, insert the balloon 2 11 through the fixing sleeve 10 onto the surface of the gas injection tube 4. Press and inject gas into the gas injection tube 4 to inflate the balloon 1 3 and get it stuck in the opening of the bladder, thus fixing the cannula 2.

[0034] At this time, the spring 7 will continue to provide elastic force to press the sealing plate 8 against the surface of the limiting plate 9, so that the interior of the gas injection pipe 4 is sealed to prevent gas leakage. The gas injection pipe 4 is fixed by the limiting clamp 13 and the fixing block 14, thereby preventing the gas injection pipe 4 from shaking or pulling at will.

[0035] Secondly, after the catheter 1 is installed, the connecting sleeve 16 is engaged with the thread 15 to connect the storage bag 17 to the catheter 1. At this time, the bandage 18 is tied to the thigh to fix the storage bag 17 to prevent the storage bag 17 from shaking and pulling due to its heavy weight, which may affect the patient's comfort.

[0036] Finally, when the interior of the storage bag 17 is almost full, the connecting sleeve 16 is engaged with the thread 15, so that the storage bag 17 can be disassembled and replaced.
