[0031] The sealing plate 51 and the support rod set on the fixed block 25 cooperate with the grooves set on another fixed block 25 that cooperate with the sealing plate 51 and the support rod to ensure the stability of the fixed block 25 during the movement. The sealing plate 51 can seal the groove between the two fixed blocks 25 to prevent the hemodialysis catheter and its accessories from entering the groove of the fixing block 25 installed on the pressure plate 41 during the fixing process, causing damage to the hemodialysis catheter and its accessories during the fixing process. The spring 6 set on the fixed block 25 is located on the outside of the support rod of the fixed block 25, ensuring the stability of the spring 6 set on the fixed block 25 during the compression process.

[0032] Specifically, a limiting block 31 is provided at one end of the slide plate 4 away from the opening of the outer bag 1 , and a groove cooperating with the limiting block 31 is provided on the side wall of the slide rail 3 .

[0033] The cooperation between the limit block 31 and the side wall groove of the slide rail 3 ensures the stability of the slide plate 4 during movement. The cooperation between the limit block 31 and the side wall groove of the slide rail 3 also plays a limiting role to prevent the slide plate 4 from being completely pulled away from the slide rail 3. The cross-sectional shape of the limit block 31 is T-shaped, which prevents the slide plate 4 from separating from the slide rail 3, thereby ensuring the stability of the slide plate 4 during the use of the device.

[0034] Specifically, a movable groove 21 is opened on the side wall of the inflation port 2, and a sealing plate 24 is installed on the movable groove 21. A stopper 22 is installed on the side wall of the movable groove 21 through a spring 6, and two groups of grooves cooperating with the stopper 22 are provided on the side wall of the sealing plate 24.

[0035] The sealing plate 24 can seal the airway connecting the inflation port 2 and the airbag 12. After the user completes the inflation of the airbag 12, the sealing plate 24 can seal the airway of the inflation port 2 to prevent the air in the airbag 12 from being deflated during the process of the user installing the sealing plug 25 onto the threaded ring 23, which would affect the working effect of the airbag 12. The cooperation between the stopper 22 and the side wall groove of the sealing plate 24 ensures the stability of the sealing plate 24 after it is installed on the moving groove 21. The shape of the tip of the stopper 22 ensures that the user can push the stopper 22 during the process of moving the sealing plate 24, thereby ensuring the stability of the sealing plate 24. The movement will not be hindered. The spring 6 arranged on the block 22 ensures that the block 22 can quickly return to its original position after moving, thereby ensuring the working effect of the block 22. A groove is arranged on the outer side wall of the sealing plate 24, which is convenient for the user to move the sealing plate 24.
