Description
Technical Field
The invention relates to the technical field of hemodialysis, in particular to a hemodialysis internal fistula training device.
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. Arteriovenous internal fistula is one of surgical operations and is mainly used for hemodialysis treatment. The arteriovenous internal fistula is a small operation for blood vessel anastomosis, wherein an artery at the part of a forearm close to a wrist and an adjacent vein are sutured, so that arterial blood flows in the anastomosed vein to form an arteriovenous internal fistula, and the blood vessel of the arteriovenous internal fistula can provide sufficient blood for hemodialysis treatment and guarantee the sufficiency of the dialysis treatment. The radial artery and the cephalic vein at one wrist of a patient are connected, so that arterial blood directly impacts into the vein wall for a long time to cause the local venous blood pressure to rise and the vein wall to thicken and expand, and the cephalic vein can obtain sufficient blood flow after several months, and can be repeatedly punctured on the vein wall to meet the requirement of long-term hemodialysis. The arteriovenous internal fistula solves the problem of the vascular access of the uremia patient for long-term dialysis, and is the most safe, most economic and longest-lasting vascular access at present.
Although arteriovenous internal fistula is a minor operation, the life of an operator is affected in the maturation process of the arteriovenous internal fistula, and some complications are easily caused when the recovery of the operator is not ideal enough, so that the arteriovenous internal fistula is very unfavorable for the operator. At present, few exercise devices aiming at postoperative recovery of arteriovenous internal fistula are available in the market to promote maturation of arteriovenous internal fistula, an operator can carry out standard and quantitative training only by means of exercise recovery of the operator without professional devices, the recovery period of the operator is long, and complications can be caused.
