Problems solved by technology

[0004] Nephrology hemodialysis filter is the basic instrument for hemodialysis. During the process of hemodialysis, the patient's blood pressure will fluctuate. Most of the existing dialysis filters cannot correct the blood pressure, and the patient will feel uncomfortable. Functional nephrology hemodialysis filter has not been found, pending further research and development

Abstract

The invention discloses a hemodialysis filter for nephrology, which includes a dialysis tank and a sphygmomanometer. The dialysis tank includes a primary dialysis tank, a secondary dialysis tank and a tertiary dialysis tank. The tank and the third-stage dialysis tank are connected end-to-end in sequence through connecting pipes, and the upper inlet of the first-stage dialysis tank is connected with the blood inlet. , to detect the blood pressure of the user in real time, and automatically control the speed of hemodialysis, thereby reducing the impact of dialysis on the blood pressure of the user. At the same time, the Hall sensor 2 is installed inside to detect the blood return speed. The reasonable proportion of the replacement fluid and the addition of an exhaust tank can effectively prevent gas from entering the blood.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nephrology hemodialysis filter. Background technique [0002] Hemodialysis, referred to as hemodialysis, is also called artificial kidney or kidney dialysis in popular terms. It is a kind of blood purification technology. Using the principle of semi-permeable membrane, through diffusion, various harmful and redundant metabolic wastes and excess electrolytes in the fluid are removed from the body, so as to purify the blood, correct the water-electrolyte and acid-base balance. [0003] According to different treatment methods, it can be divided into intermittent hemodialysis treatment and continuous hemodialysis treatment. In addition to being used in chronic renal failure replacement therapy, it is also widely used in acute renal failure caused by different reasons, multiple organ failure, severe trauma, acute necrotizing pancreatitis, hyperkalemia, hypernatremia, acute...
