Control of blood purification device

Abstract

The invention discloses a control of a blood purification device, Including a replacement box, the top of the displacement frame is fixedly connected to a first infusion frame, a second infusion frame, a third infusion frame and a fourth infusion frame, wherein the inside of the first infusion frame is provided with physiological saline and calcium chloride, the inside of the second infusion frameis provided with physiological saline and magnesium sulfate, the inside of the third infusion frame is provided with physiological saline and potassium chloride, and the inside of the fourth infusionframe is provided with physiological saline and glucose. A medicate solution is added into the first infusion frame, second infusion frame, the third infusion frame and the fourth infusion frame. Atthe same time, the display screen is opened to input the parameters to be adjusted, and the parameters are transmitted to the controller. The controller controls the size of the flow control valve toopen and close the flow port, thereby controlling the flow rate of the infusion fluid, thus the invention has the characteristics of automatic control for regulating the formula of the displacement fluid, and reducing the process operation and the human error.

Description

technical field [0001] The present invention relates to the technical field of blood purification devices, more specifically, it relates to the control of a blood purification device. Background technique [0002] Blood purification is called dialysis in daily life. Its meaning is: lead the patient's blood out of the body and pass it through a purification device to remove some pathogenic substances, purify the blood, and achieve the purpose of treating diseases. Blood purification should include: hemodialysis, hemofiltration, hemoperfusion, plasma exchange, immunoadsorption, etc. Peritoneal dialysis does not draw the blood out of the body, but the principles are the same. Hemodialysis is just one of the ways to treat chronic renal failure. [0003] Among them, the hemofiltration mainly depends on the regulation of the replacement fluid. If the liquid is not properly configured, it will lead to serious complications. At present, the replacement fluid used in clinical cont...

Problems solved by technology

Among them, the composition of the finished liquid in bags is fixed, which cannot meet the treatment requirements of all patients; while the self-dispensing liquid in bags can adjust the liquid composition in real time according to the needs of patients' conditions, but it needs to be prepared in a sterile liquid dosing room or under the ultra-clean bench. The various liquids used are filled in 3 liters and then treated

That is to say, the liquid preparation conditions are high, the process is cumbersome, and the cost is high, so a blood purification device control is required.
