[0024] Referring to Figures 2 to 4 , in an embodiment of the present utility model, an extracorporeal circulation pipeline fixing device includes: a fixed base plate 1, a chute 2 is opened on the top surface of the fixed base plate 1, a first limiting plate 3 is slidably connected inside the chute 2, a telescopic rod 4 is fixedly connected to the bottom surface of the first limiting plate 3, a second limiting plate 5 is fixedly connected to the bottom end of the telescopic rod 4, a spring member 6 is sleeved outside the telescopic rod 4, an anti-slip rubber ring 7 is fixedly connected to the top surface of the first limiting plate 3, a connecting column 8 is fixedly connected to the center of the top surface of the first limiting plate 3, an arc-shaped clamping member 9 is fixedly connected to the top end of the connecting column 8, an adjusting screw column 10 is screwed on one side of the arc-shaped clamping member 9, a limiting block 11 is fixedly connected to one end of the adjusting screw column 10, a connecting block 12 is rotatably connected to the limiting block 11, a limiting groove 13 is opened on one side of the connecting block 12, and a pipe-clamping arc plate 14 is fixedly connected to the other side of the connecting block 12.

[0025] Referring to Figures 2 to 4 , the fixed base plate 1 is set as a connecting plate structure with a J-shaped side surface. The chute 2 is opened on the top surface of the long plate of the fixed base plate 1. The spring member 6 is sleeved outside the telescopic rod 4, and the top end of the spring member 6 is fixedly connected to the bottom surface of the first limiting plate 3, and the bottom end is fixedly connected to the top surface of the second limiting plate 5. The first limiting plate 3, the telescopic rod 4, the second limiting plate 5, the spring member 6 and the anti-slip rubber ring 7 are all arranged inside the chute 2. The adjusting screw column 10 penetrates through one side of the arc-shaped clamping member 9 and is rotatably connected to the connecting block 12 through the limiting block 11 and the limiting groove 13. The number of the adjusting screw column 10, the limiting block 11, the connecting block 12, the limiting groove 13 and the pipe-clamping arc plate 14 are all set to two groups, and they are symmetrically arranged on both sides of the arc-shaped clamping member 9.

[0026] Adopting the above solution: The first limiting plate 3 and the second limiting plate 5 are elastically connected to each other through the telescopic rod 4 and the spring member 6, which is convenient for flexibly moving and rotating the positions and angles of each group of arc-shaped clamping members 9 after being inserted into the chute 2 by pressing down the first limiting plate 3. After releasing the pressing force, the friction between the first limiting plate 3 and its connecting structure and the chute 2 is increased under the action of the spring member 6 and the anti-slip rubber ring 7, so as to fix the state of the arc-shaped clamping member 9. The extracorporeal circulation pipeline drives the pipe clamping arc plate 14 to limit and clamp the pipeline through the two groups of adjusting studs 10 symmetrically arranged and passing through the arc-shaped clamping member 9.

[0027] Referring to Figure 1 , Figure 2 and Figure 5 , one end of the fixed base plate 1 is movably clamped with a cover plate 15. One side of the cover plate 15 is fixedly connected with a buckle 16. A clamping groove 17 is opened at the position corresponding to the buckle 16 at one end of the fixed base plate 1. A spring telescopic column 18 is fixedly connected to the inner side of the short plate of the fixed base plate 1. The other end of the spring telescopic column 18 is fixedly connected with a clamping plate 19. An anti-slip rubber pad 20 is fixedly connected to the side of the clamping plate 19 facing the inside of the fixed base plate 1.

[0028] Adopting the above solution: The spring telescopic column 18 and the clamping plate 19 are convenient for cooperating with the J-shaped fixed base plate 1 to conveniently clamp and install the whole device on the operating bed board or the operating table board. The anti-slip rubber pad 20 improves the friction between the clamping plate 19 and the table top.

[0029] The working principle of the present utility model is as follows: During use, the appropriate number of arc-shaped clamping members 9 are selected according to the number of extracorporeal circulation pipelines during the operation and inserted into the chute 2. The chute 2 and its connected sliding structure are convenient for adapting to different pipeline quantity requirements and can be flexibly disassembled and assembled. The first limiting plate 3 and the second limiting plate 5 are elastically connected to each other through the telescopic rod 4 and the spring member 6, which is convenient for flexibly moving and rotating the positions and angles of each group of arc-shaped clamping members 9 after being inserted into the chute 2 by pressing down the first limiting plate 3. After releasing the pressing force, the friction between the first limiting plate 3 and its connecting structure and the chute 2 is increased under the action of the spring member 6 and the anti-slip rubber ring 7, so as to fix the state of the arc-shaped clamping member 9. The extracorporeal circulation pipeline drives the pipe clamping arc plate 14 to limit and clamp the pipeline through the two groups of adjusting studs 10 symmetrically arranged and passing through the arc-shaped clamping member 9. The adjusting stud 10 is rotationally connected to the connecting block 12 on one side of the pipe clamping arc plate 14 through the limiting block 11 and the limiting groove 13, which is convenient for controlling the distance between the two groups of pipe clamping arc plates 14 by adjusting the screwing state of the adjusting stud 10 and the arc-shaped clamping member 9, flexibly adapting to different pipeline specifications, and effectively avoiding squeezing the pipeline for the bracket with a relatively fixed size, having higher versatility. The spring telescopic column 18 and the clamping plate 19 are convenient for cooperating with the J-shaped fixed base plate 1 to conveniently clamp and install the whole device on the operating bed board or the operating table board. The anti-slip rubber pad 20 improves the friction between the clamping plate 19 and the table top.
