Description

Forearm restraint device for dialysis Technical Field The utility model relates to the field of medical equipment, in particular to a forearm restraint device for dialysis. Background Hemodialysis is an important treatment means for life support of end-stage renal patients, and the purposes of purifying blood and supporting life are achieved by leading the blood of the patients out of the body, removing metabolic waste and redundant liquid in the body through a dialyzer and then returning the blood into the body. Arteriovenous fistulae are the most common vascular access for hemodialysis patients and are known as the "lifeline" of the patient. The peripheral artery and superficial vein of the patient are anastomosed through surgical operation, arterial blood flow is enabled to reach the vein, the vein is enabled to be arterialized after about 4-8 weeks, and the arteriovenous internal fistula is formed, so that vascular puncture is facilitated, and the blood flow requirement required by dialysis can be met when the patient is dialyzed. The current common constraint mode in clinic is to directly constrain the wrist, the hemodialysis patient group is special, the emergency situation is very common in the dialysis process, and the patient may have the dialysis complications such as nausea, vomit, convulsion, skin itch and the like in the dialysis process, and the body is not independently moved due to the small constraint force to the wrist, so that the internal fistula needle is shifted and falls off, and the internal fistula hematoma and other adverse nursing events are caused. Therefore, in order to solve the defects in the prior art, a forearm restraint device for dialysis with a simple structure needs to be designed. Disclosure of utility model The utility model provides a forearm restraint device for dialysis, which solves the problems in the prior art. The forearm restraint device for dialysis comprises a base, a binding belt, two groups of U-shaped plates and a limiting belt, wherein the binding belt is arranged on two sides of the base, a sliding groove is formed in the upper end of the base, a through groove is formed in the side end of the base, the bottom of the U-shaped plate slides in the sliding groove, a fastening bolt penetrating through the through groove is connected to one side of the U-shaped plate in a threaded manner, openings are formed in two sides of the side end of the U-shaped plate, a first fixing block is arranged at the lower end of one side opening of the U-shaped plate, a second fixing block is arranged at the lower end of the other side opening of the U-shaped plate, the limiting belt comprises an elastic belt and a male fastening belt which are integrally connected, one end of the elastic belt is fixed on the first fixing block, and a female fastening belt is fixed on the second fixing block and connected with the male fastening belt through a fastening belt. Further improvement, one side interval of U template is equipped with jack one, the opposite side interval of U template is equipped with jack two, fixed block one inside is fixed with the inserted bar one of matching jack one, fixed block two inside is fixed with the inserted bar two of matching jack two. Further improvement, the spout interval is equipped with three group, U-shaped board bottom is equipped with the T shape slider of matching spout. Further improvement, the base up end and the inside rubber pad that is equipped with of U template. Further improvement, the bandage is symmetrically provided with two groups. Compared with the prior art, the forearm restraint device for dialysis has the beneficial effects that: The openings at two sides of the side end of the U-shaped plate are respectively provided with a first fixed block and a second fixed block, one end of an elastic belt of the limiting belt is fixed on the first fixed block, a male fastening belt at the other end of the elastic belt is fastened with a female fastening belt on the second fixed block, the limiting belt further limits the moving range of the arm of a patient, the U-shaped plate can be used for restraining the wrist and elbow of the forearm of the patient from two sides by matching with the pre-tightened limiting belt, the moving range is reduced, and adverse events such as shifting and falling of an internal fistula needle caused by excessive movement of the arm are prevented; The sliding grooves at the upper end of the base and the through grooves at the side ends are matched with the sliding of the bottoms of the U-shaped plates and the threaded connection of the fastening bolts, so that the U-shaped plates can be flexibly adjusted in position and fixed on the base, forearms of patients are placed in the two groups of U-shaped plates, the movable U-shaped plates can also enable the puncture parts of the forearms to be fully exposed, the operation of puncturing or removing a dialysis needle by a nurse is facilitated, and the condition th
