Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a fixing device for an extracorporeal circulation pipeline. Background Technique
[0002] Hemodialysis is a method for treating chronic renal failure, which replaces the function of the kidneys through an artificial kidney (dialysis machine). The hemodialysis pipeline refers to the pipeline system used to guide blood in and out of the dialysis machine during hemodialysis. The hemodialysis pipeline is generally divided into two main parts: arterial pipeline (or inlet pipeline): draws the patient's blood out of the body and sends it into the dialysis machine. This pipeline is usually connected to the patient's artery to ensure that blood can effectively flow into the dialysis machine. Venous pipeline (or return pipeline): returns the blood processed by the dialysis machine to the patient's body, usually connected to the patient's vein.
[0003] During traditional hemodialysis treatment, the pipeline through which blood flows is usually directly placed on the hospital bed, which is rather messy. The messy pipeline increases the difficulty of management and monitoring, and it is easy to have misoperations or miss abnormal conditions of the pipeline, thus affecting the treatment effect. During the treatment process, doctors or nurses need to deal with complex pipeline arrangements, which may increase the operation difficulty and time. The pipeline placed on the hospital bed may be compressed or distorted, which may lead to poor blood flow or even blood vessel rupture, thus affecting the dialysis effect and the patient's safety. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a fixing device for an extracorporeal circulation pipeline, which solves the problems that during traditional hemodialysis, the pipeline through which blood flows is usually directly placed on the hospital bed, which is rather messy. The messy pipeline increases the difficulty of management and monitoring, and it is easy to have misoperations or miss abnormal conditions of the pipeline, thus affecting the treatment effect. During the treatment process, doctors or nurses need to deal with complex pipeline arrangements, which may increase the operation difficulty and time. The pipeline placed on the hospital bed may be compressed or distorted, which may lead to poor blood flow or even blood vessel rupture, thus affecting the dialysis effect and the patient's safety.

[0006] Preferably, side plates are fixedly connected to both side surfaces of the upper clamping plate, and the top of the pressing rod extends to the outer surface of the upper clamping plate.
[0007] Preferably, a pipeline is wound around the surface of the reel. Under normal conditions, due to the elasticity of the first spring, the lower clamping plate slides towards the upper clamping plate.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a fixing device for an extracorporeal circulation pipeline, including a fixing plate 1. A upper clamping plate 2 is fixedly connected to the side surface of the fixing plate 1. Side plates 201 are fixedly connected to both side surfaces of the upper clamping plate 2. The number of the side plates 201 is two. The surface of the side plate 201 is arc-shaped. A slider 3 is slidably connected inside the upper clamping plate 2. A pressing rod 4 is fixedly connected to the center inside the slider 3. The top of the pressing rod 4 extends to the outer surface of the upper clamping plate 2. A first spring 5 is movably installed on the outer surface of the pressing rod 4 at the bottom of the slider 3. The end of the pressing rod 4 is fixedly connected to a lower clamping plate 6. In the normal state, due to the elasticity of the first spring 5, the lower clamping plate 6 slides towards the direction close to the upper clamping plate 2. Tooth blocks 7 are fixedly connected to the opposite surfaces of the upper clamping plate 2 and the lower clamping plate 6 at equal intervals. A rotating shaft 10 is fixedly connected to the surface of the fixing plate 1. A reel 11 is rotatably connected to the outer surface of the rotating shaft 10. A pipeline is wound around the surface of the reel 11. A crank 12 is fixedly connected to the surface of the reel 11. By setting the parallel structure between the upper clamping plate 2 and the lower clamping plate 6, and the tooth blocks 7 on the opposite surfaces of the upper clamping plate 2 and the lower clamping plate 6, when clamping the mattress, the contact area can be increased, the stability after clamping can be strengthened, and the reel 11 can be firmly fixed. By setting the reel 11, the pipeline can be sorted out, and when the pipeline is pulled, through the rotation of the reel 11, the pipeline can be flexibly released, which can effectively avoid unnecessary pulling or stretching of the pipeline, thereby reducing potential damage or destruction;
[0021] A second spring 8 is fixedly connected to the surface of the fixing plate 1. One end of the second spring 8 away from the fixing plate 1 is fixedly adsorbed with a bell 9 through a magnet. The bell 9 is movably connected between the reel 11 and the fixing plate 1 through the elasticity of the second spring 8. Convex blocks 13 are fixedly connected to the surface of the reel 11 close to the bell 9 at equal intervals. The surface of the convex block 13 is arc-shaped. The surface of the convex block 13 abuts against the surface of the bell 9. By setting the second spring 8 and the convex block 13, when the pipeline is pulled, the reel 11 will be driven to rotate. When the reel 11 rotates, through the impact between the convex block 13 and the bell 9, the bell 9 can make a sound, which can remind both the nurse and the patient, thereby improving the safety and effectiveness of the treatment.
[0022] When in use, select the fixing device of the corresponding color, then wind the pipeline around the surface of the reel 11. After winding is completed, hold the side plate 201 by hand and apply pressure to the pressure lever 4. At this time, the pressure lever 4 drives the lower clamping plate 6 to slide downward, and then place the mattress between the upper clamping plate 2 and the lower clamping plate 6. After adjusting the position of the reel 11, stop applying pressure to the pressure lever 4. Through the elasticity of the first spring 5, the lower clamping plate 6 slides toward the upper clamping plate 2 and tightly clamps the mattress. By setting the parallel structure between the upper clamping plate 2 and the lower clamping plate 6, and the tooth blocks 7 on the opposite surfaces of the upper clamping plate 2 and the lower clamping plate 6, when clamping the mattress, the contact area can be increased, the stability after clamping is strengthened, and the reel 11 is firmly fixed. When the pipeline is pulled, through the rotation of the reel 11, the pipeline can be flexibly released, which can effectively avoid unnecessary pulling or stretching of the pipeline, thereby reducing potential damage or destruction. When the pipeline is pulled, it will drive the reel 11 to rotate. When the reel 11 rotates, through the impact of the convex block 13 and the bell 9, the bell 9 can make a sound, which can remind both the nurse and the patient, thereby improving the safety and effectiveness of treatment.
