Rehydration therapy liquid inlet and outlet balance system control circuit

Abstract

The invention discloses a rehydration therapy liquid inlet and outlet balance system control circuit which comprises a main controller, a blocking and air detecting unit, a single-board computer expansion unit, a battery charging and protecting unit, a motor driving unit, a weighing unit and a power supply unit. The blocking and air detecting unit, the single-board computer expansion unit, the motor driving unit, the weighing unit and the power supply unit are all connected with the main controller; and the battery charging and protecting unit is connected with the power supply unit. According to the invention, by arranging the weighing unit, the weight of an infusion bag and the weight of a urine bag can be weighed in real time, the urine flow speed is calculated through the main controller, the infusion speed is automatically adjusted in a feedback mode according to the urine flow speed, the motor driving unit drives a motor, an effect of enabling liquid in an infusion tube to directionally flow at a certain speed is achieved, balance of the intake and output volumes of liquid is implemented, liquid balance in the human body is guaranteed, and the sufficient blood volume is guaranteed while the urine volume is increased.

Description

technical field [0001] The invention relates to the technical field of hydration therapy. Specifically, it is the control circuit of the fluid balance system for hydration treatment. Background technique [0002] With the use of iodine-containing contrast media, its safety has received increasing attention. Contrast media-induced acute kidney injury is one of the common complications of coronary artery diagnosis and interventional therapy, and is accompanied by serious adverse outcomes; hydration therapy can Effectively reduce the risk of contrast-induced nephropathy; such a diuretic effect can be achieved by using large-dose diuretics and forced diuresis. In theory, furosemide protects the kidneys from contrast agent toxicity by reducing renal medullary hypoxia, but this method In fact, it has been proven to be harmful. It will affect the fluid balance in the human body, and it will not be possible to increase urine output while ensuring adequate blood volume. Contents o...
