Background

Hemodialysis (HD) is one of the alternative treatments for the kidney of patients with acute and chronic renal failure. The method comprises the steps of draining blood in vivo to the outside of the body, enabling the blood and electrolyte solution (dialysate) with similar body concentration to be inside and outside one hollow fiber through a dialyzer consisting of a plurality of hollow fibers, and carrying out substance exchange through dispersion, ultrafiltration, adsorption and convection principles, so as to remove metabolic waste in the body and maintain the balance of electrolyte and acid and alkali; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis. The principle of hemodialysis is that solutes move from a high concentration solution to a low concentration direction through a semipermeable membrane. Hemodialysis involves the movement of solutes and the movement of water, i.e., the blood and dialysate are contacted and subjected to material exchange in a dialyzer (artificial kidney) by means of a semipermeable membrane and a concentration gradient, so that metabolic wastes and excess electrolytes in the blood move to the dialysate, and calcium ions, bases and the like in the dialysate move to the blood; the hemodialysis equipment is popularized and used to save most kidney disease patients, the existing hemodialysis device is transmitted and operated through a hemodialysis pipe component, the hemodialysis pipe component is cleaned and installed after being used, the dialysis pipe component is inconvenient to install in the existing means, so that the workload of medical workers is greatly increased, the working efficiency is reduced, the temperature of blood which is returned after the hemodialysis operation is finished is close to the temperature of a human body, otherwise, the bearing capacity and the activity of the heart of the patient are reduced, and the life risk of the patient is brought; to this end, a hemodialysis tube unit and a hemodialysis apparatus are proposed.
