The inner sides of the two movable concave plates 10 close to each other are rotatably connected to the rotating extrusion rod 11.

[0049] The fixed assembly 6 also includes a toothed plate 15, a driving gear 16 and a first rotating rod 17.

The bottom of the second rotating rod 19 extends to the outside of the first rotating rod 17 located on the vertical inner side of the right-angle movable groove and is provided with a first bevel gear set 20. The second rotating rod 19 drives the first rotating rod 17 located on the vertical inner side of the right-angle movable groove to rotate through the first bevel gear set 20.

[0051] The fixing assembly 6 also includes a third rotating rod 21, a second bevel gear set 22 and a third bevel gear set 23. The third rotating rod 21 is laterally arranged in the right-angle movable groove, and the third rotating rod 21 is rotatably connected to the inner side of the corresponding mounting plate 40. One end of the third rotating rod 21 extends to the outside of the second rotating rod 19 and is provided with a second bevel gear set 22, and the second rotating rod 19 drives the third rotating rod 21 to rotate through the second bevel gear set 22. The other end of the third rotating rod 21 extends to the outside of the first rotating rod 17 located laterally inside the right-angle movable groove and is provided with a third bevel gear set 23, and the third rotating rod 21 drives the first rotating rod 17 located laterally inside the right-angle movable groove to rotate through the third bevel gear set 23.

[0052] The fixing assembly 6 also includes a fixed concave plate 24, a movable plate 25, an extrusion arc plate 26 and a fixed piece 27. The outer side of the movable concave plate 10 away from the rotating extrusion rod 11 is fixedly connected to the fixed concave plate 24. The fixed concave plate 24 and the movable concave plate 10 are both provided with a first movable groove. A movable plate 25 is provided on the inner side of the first movable groove, and the movable plate 25 is clearance-matched with the fixed concave plate 24 and the inner side of the movable concave plate 10 through the two first movable grooves. The movable plate 25 is located on the inner side of the fixed concave plate 24 away from the movable concave plate 10 and is provided with a circular hole. The end of the movable plate 25 close to the rotating extrusion rod 11 is fixedly connected to the extrusion arc plate 26, and the extrusion arc plate 26 has the effect of extruding and limiting the rotating extrusion rod 11. The top and bottom of the movable plate 25 located on the inner side of the fixed concave plate 24 are fixedly connected with fixed pieces 27.

[0053] The fixing assembly 6 also includes a second fixing rod 28, a spring 29, a third fixing rod 30 and a limiting plate 31. The top and bottom of the inner side of the fixed concave plate 24 are fixedly connected with the second fixing rod 28, and the second fixing rod 28 is slidingly connected to the inner side of the fixing plate 27. A spring 29 is provided on the outside of the second fixing rod 28. The spring 29 is located between the fixing plate 27 and the fixed concave plate 24, and the two ends of the spring 29 are fixedly connected to the fixing plate 27 and the fixed concave plate 24 respectively. The top of the fixed concave plate 24 away from the end of the movable concave plate 10 is fixedly connected with the third fixing rod 30. The outer side of the third fixing rod 30 is rotatably connected to the limiting plate 31. A limiting groove is provided at the top of the movable plate 25, and the limiting plate 31 is provided with a limiting matching arrangement with the limiting groove.

[0054] Specifically: after the conduit passes through the inner side of the flow port opened in the fixed plate 8, the first motor 18 is turned on to drive the second rotating rod 19 to rotate, thereby driving the first rotating rod 17 located vertically inside the right-angle movable groove to rotate through the setting of the first bevel gear set 20. At the same time, the setting of the second bevel gear set 22 can drive the third rotating rod 21 to rotate synchronously, and the setting of the third bevel gear set 23 can drive the first rotating rod 17 located laterally inside the right-angle movable groove to rotate synchronously.

[0055] When the two first rotating rods 17 rotate, the driving gear 16 can be driven to rotate synchronously. At the same time, the meshing connection between the driving gear 16 and the two tooth plates 15 can drive the two tooth plates 15 to move toward one end closer to each other and insert into the inner side of the opposite reserved groove, thereby driving the two movable concave plates 10 to move closer to each other.

[0056] When the movable concave plate 10 moves, it can drive the movable block 14 to move synchronously inside the fixed groove plate 12. The sliding connection between the first fixed rod 13 and the movable block 14 can connect and support the movable concave plate 10, and can also guide the moving path of the movable concave plate 10.

[0057] When the two movable concave plates 10 move toward one end close to the outer side of the catheter, the inner side of the movable concave plates 10 can be rotated to connect the rotating extrusion rods 11 close to the outer side of the catheter. At this time, the outer side of the catheter can be clamped by the four rotating extrusion rods 11.

[0058] At the same time, the elastic setting of the spring 29 can push the fixed plate 27 to move toward one end of the rotating extrusion rod 11, thereby driving the movable plate 25 fixedly connected to the fixed plate 27 to move toward one end of the rotating extrusion rod 11, and the movable plate 25 drives the extrusion arc plate 26 to fit the outer side of the rotating extrusion rod 11. The extrusion arc plate 26 cooperates with the extrusion limiter on the outer side of the rotating extrusion rod 11 to limit the rotation effect of the rotating extrusion rod 11, thereby achieving a fixing effect on the catheter.

[0059] When the position of the catheter needs to be adjusted, the circular hole provided in the movable plate 25 can be pulled to move the movable plate 25 toward the end away from the rotating extrusion rod 11. At this time, the movable plate 25 will drive the extrusion arc plate 26 to break away from the extrusion fit with the rotating extrusion rod 11, and at the same time drive the two fixing plates 27 to slide outside the second fixing rod 28, thereby exerting an extrusion effect on the spring 29.

[0060] The rotation position of the third fixing rod 30 and the limiting plate 31 is set away from the center of the circle of the limiting plate 31. When the limiting groove opened on the top of the movable plate 25 moves to the end of the fixed concave plate 24 away from the movable concave plate 10, the limiting plate 31 can be rotated to the inner side of the limiting groove opened on the top of the movable plate 25, thereby fixing the position of the movable plate 25. At this time, the rotating extrusion rod 11 loses the extrusion limiting cooperation of the extrusion arc plate 26 and can be rotated inside the movable concave plate 10, so that the catheter can be directly dragged and the catheter position can be adjusted conveniently.

[0061] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.

[0062] Example 3

[0063] This embodiment 3 is used to further disclose the specific structure of the adjustment component 7 on the premise of the above embodiment. By cooperating with the adjustment component 7 and the structure of the above embodiment, the setting of re-adjusting the part of the catheter clamping and fixing is achieved. After the device is fixed to the edge of the bed, the position of the catheter can be readjusted according to actual conditions, thereby further improving the flexibility of adjusting the catheter position.

[0064] The catheter fixing device provided in Example 1 and Example 2 is further optimized. Specifically, Figure 9-10As shown, the adjustment assembly 7 includes a second motor 32, a turntable 33, a scissor-type telescopic frame 34, a movable foot 35, a fourth fixed rod 36 and a fixed foot 41. A circular movable groove is opened on the top of the fixed concave box 1, and the second motor 32 is fixedly connected to the bottom of the inner side of the circular movable groove. The output end of the top of the second motor 32 is fixedly connected to the turntable 33. The turntable 33 and the circular movable groove are set with a clearance fit. The two ends of the top of the turntable 33 are installed with a scissor-type telescopic frame 34, and the top and bottom of the same side of the scissor-type telescopic frame 34 are installed with fixed feet 41. , and movable feet 35 are installed on the top and bottom of the other side of the scissor-type telescopic frame 34, and the fixed feet 41 are fixedly connected to the corresponding bottom of the movable platform 5 and the top of the turntable 33 respectively. A second movable groove is provided at both ends of the bottom of the movable platform 5 and the top of the turntable 33 away from the fixed feet 41. The position of the second movable groove corresponds to the movable foot 35, and the movable feet 35 extend to the inside of the second movable groove and are slidably connected to the inside of the second movable groove. A fourth fixed rod 36 is fixedly connected between the two movable feet 35 located below.

[0065] The adjustment assembly 7 also includes a fixed block 37, an electric push rod 38 and a fixed ring 39. The top of the turntable 33 is fixedly connected to the side away from the fourth fixed rod 36 with a fixed block 37, the side of the fixed block 37 close to the fourth fixed rod 36 is fixedly connected to the electric push rod 38, and the output end of the electric push rod 38 is fixedly connected to the fixed ring 39, which is arranged to wrap around the outside of the fourth fixed rod 36.

[0066] Specifically, by turning on the electric push rod 38 and driving the fixing ring 39 to move toward the side close to the fixing block 37, the fourth fixing rod 36 inside the fixing ring 39 can be driven to move synchronously. When the fourth fixing rod 36 moves toward the fixing block 37, the movable feet 35 at the bottom of the scissor-type telescopic frame 34 can be driven to move synchronously, thereby stretching the scissor-type telescopic frame 34 upward, thereby raising the height of the movable platform 5 on the top, and thus raising the catheter on the top of the movable platform 5 to a suitable height.

[0067] At the same time, through the setting of the second motor 32, the turntable 33 can be driven to rotate inside the circular movable groove, so that the movable platform 5 can be synchronously rotated on the top of the fixed concave box 1 through the connection setting of the scissor-type telescopic frame 34, thereby further improving the adjustment range of the catheter on the top of the movable platform 5, thereby further improving the convenience of the operation.

[0068] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.
