Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis, in particular to a children's hemodialysis catheter fixing belt. Background Art

[0002] Hemodialysis (HD) 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 through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing a concentration similar to that of the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.

[0003] In the existing technology, a hemodialysis catheter fixing device for nephrology is proposed with the publication number of CN214049959U, which includes a fixing box, a catheter fixing plate, a magnetic strip, a fixing card plate, a card block and a push plate, one side of the push plate is fixedly connected with a spring, the other side of the push plate is fixedly connected with a pressing rod, one end of the pressing rod is fixedly connected with a pressing cap, and the lower surface of the fixing box is fixedly connected with a fixing plate. The main advantage of the utility model is to provide a hemodialysis catheter fixing device for nephrology. The device provides a catheter fixing structure, which avoids the movement of the patient's arm during hemodialysis, thereby causing the catheter to fall off, increases the connection stability of the catheter during hemodialysis, avoids secondary intubation caused by the catheter falling off, enables medical personnel to arrange the catheter in order when using it, makes it easier for medical personnel to distinguish the function and direction of the catheter, and is beneficial for medical personnel to organize the catheter when the patient undergoes hemodialysis.

[0004] In order to solve the problem that due to the long hemodialysis time, the child patient may unconsciously move the arm undergoing catheter dialysis, causing the catheter to fall off, requiring medical staff to perform secondary intubation, and even causing infection in severe cases, the existing technology uses magnetic fixation to deal with it. However, although the catheter can be fixed, it is necessary to tie the catheter to the child's arm or thigh. Such operation is likely to cause paralysis of the child's arm or thigh after a long time, causing physical discomfort, which in turn leads to reduced utilization efficiency of the catheter fixing device.
