This utility model discloses a fistula restraint device specifically for hemodialysis patients, belonging to the technical field of fistula restraint devices. It includes an upper arm support strapped to the patient's upper arm and a lower arm support strapped to the patient's forearm. An extendable upper telescopic arm is fixed to the outer wall of the upper arm support, and an extendable lower telescopic arm is fixed to the outer wall of the lower arm support. A connecting member rotatably connects the upper and lower telescopic arms. The connecting member includes an upper connecting seat fixed to the bottom of the upper telescopic arm and a lower connecting seat fixed to the top of the lower arm support. A fixing plate is fixed to the front side of the upper connecting seat. This utility model uses two limiting rings to restrict the angle of the lower telescopic arm strapped to the forearm, allowing the patient's forearm to be restrained by the upper and lower telescopic arms while also allowing for a small range of rotation within the limitation of the limiting rings. This prevents the patient's arm from becoming stiff or numb due to prolonged immobility during hemodialysis, thus improving patient comfort during hemodialysis.
