[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a pipeline fixing device for extracorporeal membrane oxygenation, comprising: an extracorporeal membrane oxygenation machine assembly 1, comprising an extracorporeal membrane oxygenation machine 11, a support plate 12 arranged in the middle of the extracorporeal membrane oxygenation machine 11; a pipeline limiting assembly 2, comprising a mounting frame 21 slidably arranged on the support plate 12, and a limiting member 22 arranged on the mounting frame 21;

[0022] When in use, the pipeline is placed on the mounting bracket 21, and the pipeline can be fixed by the limiter 22 to prevent the pipeline from falling off, thereby affecting the continuity of treatment and the safety of the patient. When in use, the pipeline can be pulled to move the mounting bracket 21 on the support plate 12 to reach the designated position for use, and the position and direction of the pipeline can be conveniently adjusted to meet different treatment needs, which greatly improves the flexibility and adjustability of the device.

[0023] Specifically, the mounting frame member 21 includes a mounting frame body 211, a screw rod 212 is fixedly connected to the lower end of the mounting frame body 211, a threaded ring 213 is rotatably connected to the outer side of the screw rod 212, a pipeline limiting groove 214 is provided on the mounting frame body 211, and a limiting groove 215 is provided on the mounting frame body 211; wherein, a rubber ring is provided on the pipeline limiting groove 214, and the rubber ring can prevent the pipeline from sliding.

[0024] Specifically, the limiting member 22 includes an arc-shaped clamping block 221 , a spring 222 is fixedly connected to one side of the arc-shaped clamping block 221 , and a shifting block 223 is also fixedly connected to the outer side of the arc-shaped clamping block 221 .

[0025] Specifically, the arc-shaped clamping block 221 is limitedly slidably embedded in the limiting groove 215 , one end of the spring 222 is fixedly connected to the arc-shaped clamping block 221 , and the other end of the spring 222 is fixedly connected to the mounting frame body 211 .

[0026] As can be seen from the above, holding the pipeline and pushing the arc block 221 can make the arc block 221 move into the limit groove 215. At this time, the pipeline can be embedded in the pipeline limit groove 214. When the arc block 221 moves, the spring 222 is also compressed in the limit groove 215. When the pipeline is completely inserted into the pipeline limit groove 214, the spring 222 resets and makes the arc block 221 move, so that the pipeline is pressed against the pipeline limit groove 214, thereby playing a fixing role.

[0028] Specifically, the screw rod 212 is limitedly slidably embedded in the arc-shaped guide frame 122 through the threaded ring 213 .

[0029] As can be seen from the above, the support base 112 can support the instrument, a number of movable wheels 113 can facilitate the staff to transfer positions, the support plate body 121 can provide separated support, and the arc-shaped guide frame 122 can facilitate the screw 212 to be fixed through the threaded ring 213, so that the extracorporeal membrane oxygenation machine assembly 1 is fixed.
