Embodiment Construction

[0012] As shown in the figure, a limb immobilization device for hemodialysis includes a base plate 1 and a left base 2 and a right base 3 symmetrically arranged on the base plate 1. The opposite surfaces of the left base 2 and the right base 3 are uniform. It is an arc surface, and the arc surfaces of the left base 2 and the right base 3 are sequentially provided with a canvas layer and a sponge layer from the outside to the inside, which are soft and comfortable during use, and the canvas layer can be removed for cleaning after use. The left base 2 is arranged on the base plate 1 through the slide rail 4, the slide rail 4 is arranged on the two ends of the length direction of the left base 2, the right base 3 is fixedly arranged on the base plate 1, the left base 2 and the right base 3 The lower end of the left base 2 is connected by an elastic bandage 5, the upper end of the left base 2 is hinged with an arc-shaped fixed cover 6, and the other end of the arc-shaped fixed cove...

Abstract

The invention relates to a limb fixator for hematodialysis. The limb fixator comprises a baseplate, a left base and a right base, opposite faces of the left base and the right base are arc surfaces, the left base is arranged on the baseplate through a sliding rail, the sliding rails are arranged at two ends of the left base in the length direction, the right base is fixedly arranged on the baseplate, the lower ends of the left base and the right base are connected through an elastic bandage, an arc fixing cover is hinged to the upper end of the left base, an elastic fixing strip is arranged at the other end of the elastic fixing cover and connected with the right base through an magic tape, an adjusting bolt is penetratingly arranged in the middle of the bottom of the right base, and a threaded rod of the adjusting bolt penetrates the right base to be disposed in a gap between the left base and the right base. By the limb fixator which is safe and reliable, accidents such as needle falling and blood vessel puncture during hematodialysis can be prevented, the limb fixator can be adjusted according to different physiques of patients so as to make the patients to feel more comfortable after limb fixation, and normal operation of hematodialysis is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a limb fixation device for hemodialysis. Background technique [0002] Hemodialysis is one of the effective treatment measures for patients with chronic renal failure and uremia. Establishing vascular access is the prerequisite for hemodialysis and the lifeline for hemodialysis patients. At present, more than 80% of uremia patients in our country need hemodialysis treatment, and the dialysis time of the patients is more than 4 hours. During the dialysis process, the patients are prone to needle removal and blood vessel puncture during sleep, sitting up and involuntary activities. The commonly used part of hemodialysis is generally the arteriovenous fistula of the upper extremity. Simply put, the arteriovenous fistula is to anastomose the arterial end and the venous end of the blood vessel of the upper extremity to make the vein arterial and increase the venous blood f...
