A dual-purpose arteriovenous fistula warning ring

Abstract

A dual-purpose internal arteriovenous fistula warning ring comprises a flexible band-shaped body, wherein the middle of the front side of the band-shaped body is provided with an injection operation forbidding sign, and hook-and-loop fasteners are arranged at two ends of the band-shaped body. An adhesive sticker is arranged on the back side of the band-shaped body. Tearable folding lines are arranged at the positions, close to the hook-and-loop fasteners, of the band-shaped body respectively. A pair of through holes is symmetrically formed in two sides of the injection operation forbidding sign of the band-shaped body. A pair of oblique folding lines are symmetrically arranged on two sides of the injection operation forbidding sign and are located on the through hole on the side and the injection operation forbidding sign. The dual-purpose internal arteriovenous fistula warning ring is simple in structure, convenient to manufacture and convenient to use. When the dual-purpose internal arteriovenous fistula warning ring is used, the warning ring is firstly worn on the arm on the side the internal arteriovenous fistula is simulated and is fixed through the hook-and-loop fasteners to play a warning role. After an internal arteriovenous fistula operation, the warning ring on the wrist can be dismounted and is fixed and adhered to the clothes of the arm on the affected side through the hook-and-loop fasteners to continue to play the warning role and can be also folded into a silk ribbon through the folding lines to be fixed to the clothes of a patient.

Description

technical field [0001] The invention relates to a dual-purpose arteriovenous fistula warning ring, which belongs to the field of auxiliary medical devices. Background technique [0002] With the acceleration of the aging population, the incidence of chronic kidney disease worldwide is increasing year by year. Epidemiological studies in my country show that the prevalence of CKD in Chinese adults was 10.8% in 2012, and the number of patients with renal replacement therapy is increasing at an annual rate of 11%. increment. Hemodialysis is the most commonly used renal replacement therapy for patients with ESRD worldwide. Well-functioning vascular access is essential for adequate dialysis in hemodialysis patients. Compared with other vascular access, autogenous arteriovenous fistula has the advantages of long service life, fewer complications, lower mortality rate, lower hospitalization rate and lower cost rate, so the concept of "internal fistula first" vascular access has bee...

Problems solved by technology

A marker pen should be used to mark the blood vessels of the upper extremity on the side where internal fistula operation is to be performed. However, this feature is not obvious and cannot be regarded as a mark with a fixed meaning, and it is easy to disappear. Therefore, a design that can solve the above problems is needed
