[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at similar concentrations to the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body and maintain electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The entire process is called hemodialysis.
[0003] At present, the extracorporeal fixing device of the hemodialysis tube fixes and clamps the dialysis tube by a simple clip. However, the simple clip fixing device is easy to squeeze the dialysis tube, thereby causing the flow rate to change during blood circulation. Moreover, other fixing devices are poor in stability when fixing the dialysis tube, and the dialysis tube is easy to fall off, resulting in poor use effect. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an in vitro fixing device for a hemodialysis tube, applied to a dialysis machine, the hemodialysis tube includes a dripping bucket and a connecting tube, a dripping bucket is arranged on the right side of the dialysis machine, and connecting tubes are arranged at the top and bottom ends of the dripping bucket, the in vitro fixing device for the hemodialysis tube also includes: a fixing mechanism, which is arranged on the right side of the dialysis machine.
[0006] The baffle rotates, and then the user picks up the drip bucket and inserts the connecting pipe into the slot block. The user then moves the drip bucket downward and inserts it into the slot block. The user then loosens the baffle, and the baffle rotates and fits with the top block through the torsion spring inside the connection between the baffle and the slot block to block the connecting pipe.
[0007] Preferably, a through slot is provided on the right side of the slot block.
[0008] Preferably, a torsion spring is processed at the connection between the baffle and the slot block.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is arranged such that when the extracorporeal fixing device of the hemodialysis tube is put into use, the work of hemodialysis for the patient is achieved through the coordinated use of the dialysis machine, the drip bucket and the connecting tube, and the work of fixing the dialysis tube during use is achieved through the use of the fixing mechanism. The coordinated use of the above-mentioned structure solves the problem that the current dialysis tube fixing device is unstable in fixing the dialysis tube during use and is prone to falling off, and is prone to squeezing the dialysis tube, thereby causing a change in the blood flow rate.
