Hemodialysis internal fistula training device

Abstract

The invention discloses a hemodialysis internal fistula training device. Through the arrangement of a first servo electric cylinder and a second servo electric cylinder, lifting-falling adjustment ona supporting plate can be achieved, the arm of a patient is conveniently lifted, and edemas of the limbs can be reduced; through the arrangement of a first sliding groove, a second sliding groove, a first sliding strip and a second sliding strip, the stability of the supporting plate in the process of lifting and falling can be improved; through the arrangement of a water storage bag, the comfortof elbow support can be conveniently improved; through the arrangement of a ball screw, a screw nut, a connecting block and a forward and reverse motor, horizontal adjustment of a sliding plate can beachieved, and the patient can be conveniently subjected to different kinds of training; through the arrangement of a support, an elastic rope and a gripping ball, the patient can be subjected to gripstrength training; through the arrangement of a finger strength training apparatus, the patient can be subjected to finger strength training; through the arrangement of a second slide rail, a slidingblock, a second spring and a pushing plate, the patient can be subjected to wrist training.

Description

technical field [0001] The invention relates to the technical field of hemodialysis, in particular to a hemodialysis internal fistula training device. Background technique [0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. The whole process of exchanging substances with the principle of convection, removing metabolic waste in the body, maintaining electrolyte and acid-base balance; at the same time removing excess water in the body, and returning the purified blood is called hemodialysis. Arteriovenous fistula is one of the surgical procedures, mainly used for hemodialysis treatment. Arteriovenous fistula is a small operation of vascular anastomosis. The artery near the wrist of the forearm and the adjacent vein are sutured, so that arterial blood flows in the vein after anastom...

Problems solved by technology

[0003] Although the arteriovenous fistula is a minor operation, it will still affect the life of the operator during the maturation process of the arteriovenous fistula, and when the operator recovers unsatisfactorily, it is easy to cause some complications, which is very unfavorable to the operator

At present, there are few exercise devices on the market for the recovery of arteriovenous fistulas to promote the maturity of arteriovenous fistulas. They only rely on the operator's own exercise recovery without professional equipment for the operator to perform standardized and quantitative training. The recovery period of the patient is longer, and complications may also occur
