Embodiment Construction

[0014] As shown in the figure, an upper limb immobilizer for hemodialysis includes a base plate 9, a base plate 1, and a left base 2 and a right base 3 symmetrically arranged on the base plate 1, the left base 2 and the right base The arc surface of 3 is provided with a canvas layer and a sponge layer sequentially from the outside to the inside, which is soft and comfortable during use, and the canvas layer can be removed for cleaning after use. One end of the base plate 1 and the bottom plate 9 are hinged to each other, and two struts 10 are symmetrically arranged at both ends of the width direction of the base plate 1, and the two struts 10 are all hinged on the base plate 1, and the two ends of the width direction of the base plate 9 are correspondingly braced. The bar 10 is provided with an adjusting plate 11, and the adjusting plate 11 is provided with a bar-shaped chute 12, and the strut 10 is fixed in the bar-shaped chute 12 on the adjusting plate 11 by bolts, and the le...

Abstract

The invention relates to an upper limb fixing apparatus for hemodialysis. The upper limb fixing apparatus comprises a bottom plate, a base plate, a left base and a right base. The left base and the right base are symmetrically arranged on the base plate, one end of the base plate is hinged to the bottom plate, the base plate is symmetrically provided with two support rods, the support rods are hinged onto the base plate, the bottom plate is provided with adjusting plates which correspond to the support rods, the support rods are fixed into strip-shaped slide grooves in the adjusting plates by the aid of bolts, arc surfaces are respectively arranged on the opposite surfaces of the left base and the right base, the left base is arranged on the base plate via slide rails, the right base is fixedly arranged on the base plate, the lower end of the left base is connected with the lower end of the right base by elastic bandage, and an adjusting bolt is penetratingly arranged in the middle of the bottom of the right base. The upper limb fixing apparatus has the advantages that accidents such as needle dropping and blood vessel piercing in hemodialysis procedures can be prevented, and the upper limb fixing apparatus is safe and reliable; the upper limb fixing apparatus can be adjusted according to different physiques of patients, so that the patients feel comfortable after the limbs of the patients are fixed by the aid of the upper limb fixing apparatus, and normal hemodialysis can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an upper limb immobilizer 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 bloo...
