Working principle: the compression preventing device for the femoral vein catheterization based on blood purification adopts the bed body fixing support to suspend and fix the suspended bearing seat 1 and support the suspended bearing seat 1, at the moment, the U-shaped compression preventing frame 5, the upper clamping plate 6 and the lower bearing plate 7 are utilized to realize clamping and limiting of a femoral vein catheterization pipeline for blood purification, so that discomfort caused by the compression of the pipeline on a human body is prevented, the supporting and limiting of the pipeline is also provided, and the contact part of the pipeline and the human body is prevented from being compressed;
when the anti-compression U-shaped frame 5, the upper clamping plate 6 and the lower bearing plate 7 are used for clamping the blood purification femoral vein catheterization pipeline, the pipeline is firstly attached to the bottom of the second rubber block 701, and then the whole of the lower bearing plate 7 and the positioning clamping plate 8 is in butt joint with the anti-compression U-shaped frame 5;
during installation, the positioning clamping plate 8 is clamped with the inside of the anti-compression U-shaped frame 5, and meanwhile the push handle 904 is pulled, so that the push handle 904 drives the sliding column 903 and the locking rod 901 to integrally transversely move and press the second spring 902, when the locking sleeve 9 is positioned between the two groups of positioning blocks 501, the push handle 904 is loosened, the sliding column 903 and the locking rod 901 are pulled and pushed to move by using the second spring 902, the locking rod 901 is inserted into the locking hole 502, and further the installation of the whole lower bearing plate 7 and the positioning clamping plate 8 on the anti-compression U-shaped frame 5 is realized;
finally, the position of the upper clamping plate 6 is adjusted to enable the upper clamping plate 6 to drive the first rubber block 601 to move, and the pipeline is clamped and limited through the first rubber block 601 and the second rubber block 701, so that the pipeline is supported, and the pipeline is prevented from being pressed against a body;
when the position of the upper clamping plate 6 is adjusted, the rotating handle 6021 is directly rotated, so that the rotating handle 6021 drives the adjusting screw 602 to rotate, and the adjusting screw 602 pushes the upper clamping plate 6 and the first rubber block 601 to integrally move.
After the first rubber block 601 and the second rubber block 701 clamp the blood purification femoral vein catheterization pipeline, the pipeline is supported and simultaneously subjected to double buffering, when the pipeline is pulled by external force, the whole anti-compression U-shaped frame 5 is synchronously driven to move, the anti-compression U-shaped frame 5 drives the connecting pipe 4 to move, the connecting pipe 4 drives the sliding block 301 to move, the sliding block 301 presses the first spring 302 and simultaneously applies thrust to the damper 303, so that the preliminary buffering of stress on the pipeline is realized;
after the pipeline is stressed, the second rubber block 701 at the bottom and the lower bearing plate 7 are simultaneously applied with thrust, so that the lower bearing plate 7 moves, the lower bearing plate 7 extrudes the metal elastic sheet 702 to deform, and the gravity center between the lower bearing plate 7 and the positioning clamping plate 8 is close to form secondary buffering, thereby avoiding unstable phenomenon caused by overlarge stress of the pipeline and preventing the pipeline and the body part from being pressed;
the deformation of the metal elastic sheet 702 buffers the thrust, and meanwhile, the compression rod 703 is driven to move and extrude the pressure sensing alarm 704, when the pressure sensing alarm 704 exceeds a set threshold value, the pressure sensing alarm 704 alarms, on-site personnel is prompted to observe whether a pipeline and a body connection part have a shift or loose phenomenon or not, the pipeline is prevented from being separated from the body part after being stressed too much, and safety early warning is achieved.
To sum up, this prevent compression device based on blood purification femoral vein intubate utilizes unsettled carrier seat 1 and bed body fixed bolster to realize supporting the device wholly fixedly, through prevent oppression U-shaped frame 5, go up grip block 6 and lower carrier plate 7 realize providing the centre gripping spacing to blood purification femoral vein intubate pipeline, realize the pipeline and support, avoid the pipeline oppression health, when the pipeline receives external force, the pipeline can receive the preliminary buffering of buffer tank 3 and connecting pipe 4 and the secondary buffering of metal shell fragment 702, avoid the pipeline to receive external force and make pipeline and body junction part receive the compressive force too big and appear shifting or drop the phenomenon, simultaneously, when metal shell fragment 702 takes place deformation, synchronous can drive depression bar 703 extrusion pressure sensor alarm 704, real-time supervision atress degree carries out the safety precaution, when the pipeline atress exceeds the buffering degree of preventing the oppression device, real-time alarm, in time suggestion medical staff inspection blood purification femoral vein intubate pipeline, guarantee that the pipeline is connected stably, guarantee blood purification treatment process security.
