Description
Technical Field
The utility model relates to the technical field of medical treatment, specifically be an extracorporeal circulation connecting pipe for hemodialysis.
Background
Dialysis is a separation and purification technique that separates small molecules from biological macromolecules by the principle of diffusion of small molecules through a semi-permeable membrane into water (or buffer). Dialysis therapy is a treatment method in which components (solutes or moisture) in body fluid are discharged to the outside of the body through a semipermeable membrane, and is generally classified into hemodialysis and peritoneal dialysis.
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 semi-permeable membrane used for hemodialysis has a thickness of 10-20 micrometers, and the average pore diameter on the membrane is 3 nanometers, so that only small molecules with a molecular weight of less than 1.5 ten thousand and partial medium molecular substances are allowed to pass through, but macromolecular substances with a molecular weight of more than 3.5 ten thousand cannot pass through. Thus, proteins, pyrogens, viruses, bacteria, blood cells, etc. are all impermeable; most of urine components are water, and a large amount of water must be removed from blood to replace kidneys with artificial kidneys, which can remove excessive water only by osmotic pressure and ultrafiltration pressure. The hemodialysis apparatus, which is an artificial kidney, has these functions, and thus adjusts the quality and quantity of blood to be close to physiological conditions.
At present, when a patient clinically performs hemodialysis, if a dialyzer or a venous pot is blocked, blood in a pipeline cannot return to a human body any more, blood coagulation is easy to occur, the blood can only be discarded along with the pipeline, and the blood of the patient is wasted, so that the extracorporeal circulation connecting pipe for hemodialysis is designed.
