Adjustable internal arteriovenous fistula protector

Abstract

The invention discloses an adjustable internal arteriovenous fistula protector which comprises an angle adjusting supporting device and an internal fistula protection sleeve. The angle adjusting supporting device comprises a base, a supporting plate and a supporting plate, one end of the supporting plate is hinged to one end of the base, one end of the supporting plate is hinged to the other end of the base, and the supporting plate can support the bottom face of the supporting plate through the free end of the supporting plate. The internal fistula protection sleeve comprises a U-shaped supporting groove, hollowed gridding cloth is fixedly arranged on an upper gap of the U-shaped supporting groove, a zipper for opening and closing the hollowed gridding cloth is arranged in the middle of the hollowed gridding cloth, and hook and loop fasteners are arranged on the upper surface of the supporting plate and the lower end of the U-shaped supporting groove. The angle can be adjusted; the adjustable internal arteriovenous fistula protector is hung on the breast to protect an operation limb when a patient gets off the bed to stand, the limb on the other side can freely move, and limb swelling caused by ptosis is avoided. A layer of cotton cushion middle zipper is arranged at the limb containing position, a warmth keeping function is achieved, and meanwhile, the accessory function of the postoperative limb can be observed conveniently.

Description

technical field [0001] The invention relates to the medical field, in particular to an adjustable arteriovenous fistula protector. Background technique [0002] Hemodialysis is the most commonly used renal replacement therapy for patients with end-stage renal disease worldwide, accounting for 70% to 80% of all patients undergoing renal replacement therapy. Epidemiological studies in my country show that the number of patients with renal replacement therapy is more than 11% per year. Speed ​​increases. [0003] The prerequisite for hemodialysis is to have a reliable vascular access, and the quality of vascular access will directly affect the patient's dialysis and quality of life. The hospitalization rate of maintenance hemodialysis patients due to vascular access problems is still as high as 20%, which brings huge medical pressure and heavy economic burden to families and society. [0004] Arteriovenous fistula is a commonly used vascular access for maintenance hemodialysis...

AI Technical Summary

Problems solved by technology

The maturation of internal fistula is a complicated process. Clinically, in order to reduce the edema of the patient's surgical limb after surgery, the patient is instructed to raise the surgical limb higher than the heart or >30°. After 3 days, perform fist clenching exercises. No studies have shown the effect of different elevation angles on edema

Clinically, the patient's compliance is poor, and the expected effect cannot be achieved at all.

Postoperative limb swelling does not subside, functional exercise is not up to standard, affecting the maturity of arteriovenous fistula

[0005] At present, the clinical solution after arteriovenous fistula surgery is to use pillows or back pads to elevate the fistula-side limbs, but the pillow has disadvantages such as poor support, easy deformation, difficult to grasp and fix the angle, and the back of the hand is swollen after 3 days. Patients cannot perform functional exercises well and have poor compliance
