Hemodialysis monitoring and nursing control system and method based on Internet of things

Abstract

The invention belongs to the technical field of hemodialysis, and discloses a hemodialysis monitoring and nursing control system and method based on the Internet of things. A hemodialysis monitoring and nursing control system based on the Internet of things comprises a heart rate detection module, an arteriovenous pressure detection module, a blood flow detection module, a temperature detection module, a central control module, a bacteria filtration module, a dialysis module, an internet-of-things communication module, an evaluation module, an alarm module and a display module. An urea kineticmodel is analyzed by the evaluation module, the urea clearance rate, the dialysis time and the blood urea nitrogen before and after dialysis of a dialyzer are used for calculating urea distribution volume, and therefore, the protein decomposition rate is calculated, in consideration of individual conditions of different patients, a calculated result is consistent to an actual proteolysis condition; and meanwhile, the safety of hemodialysis is improved through the alarm module.

Description

technical field [0001] The invention belongs to the technical field of hemodialysis, and in particular relates to a hemodialysis monitoring and nursing control system and method based on the Internet of Things. Background technique [0002] Hemodialysis, clinically means the removal of some waste products in the blood through a semi-permeable membrane. Hemodialysis is one of the safer, easier and widely used methods of blood purification. Dialysis is the movement of solutes from a solution of high concentration to a solution of low concentration through a semipermeable membrane. Hemodialysis includes the movement of solutes and water, that is, the blood and dialysate exchange substances in the dialyzer (artificial kidney) through semi-permeable membrane contact and concentration gradients, so that metabolic waste and excess electrolytes in the blood are transferred to the dialysate. Move, the calcium ions and bases in the dialysate move to the blood. If the mixture of alb...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: in the existing hemodialysis process, the calculation of proteolysis is relatively rough, and the individual conditions of different patients are not considered, which will cause a large gap between the calculation results and the actual proteolysis; at the same time, There are a large number of patients undergoing hemodialysis for a long time, and the hemodialysis room in the hospital is basically in a saturated state. One hemodialysis medical staff may need to monitor the hemodialysis of multiple patients at the same time, which is time-consuming and laborious, and the safety is low.
