Background
In the prior art, when hemodialysis is performed, a hemodialysis machine is mainly implemented equipment, and mainly comprises a blood pump, a compound pump, a dewatering pump, a pressure sensor, a temperature sensor, a conductivity sensor, a data processing system, a display screen and other components. Hemodialysis machines are extracorporeal circulation devices for removing metabolites, abnormal plasma components, and accumulating drugs or toxins in the body, etc. from the blood, to correct electrolytes in the body and maintain acid-base balance. The hemodialysis machine works on the principle that the dialysate passes through the dialyzer to perform solute dispersion, permeation and ultrafiltration with the blood of a patient, the acted blood returns to the body of the patient, and the dialyzed liquid is discharged as waste liquid.
For different dialysis patients, doctors can give different hemodialysis treatment prescriptions, wherein the blood flow and the dialysate flow can be floated, however, if the dialysis machine is detected under the condition of no operation, the detection result can be inaccurate; if the detection is performed during the treatment of the patient, if the operation is not proper, an alarm can be triggered to stop the treatment, and the safety risk exists. Therefore, in the simulation operation process of the dialysis machine, it is particularly important to realize dynamic detection of dialysis parameters, and record, store, calculate and derive detection results in real time.
However, after the hemodialysis machine in the hospital and the dialysis center is operated for a long time, the screen display value and the actual value are different due to equipment abrasion and aging, so that the treatment effect of the same patient is different when the same dialysis parameter treatment is performed by different dialysis machines, and the fine differentiated treatment cannot be performed on the patient. When the same patient is treated by the same dialysis machine, the actual treatment data and the prescription data are different, and the ideal treatment effect cannot be achieved. Currently, the mass detector of the hemodialysis machine is used for correcting the temperature, the pH value, the pressure and the conductivity of the hemodialysis machine mainly through a pressure gauge and a conductivity meter. But neglects parameters such as blood flow rate, dialysate flow rate, ultrafiltration volume, fluid replenishment volume and the like, and real-time recording, storage, calculation and derivation of monitoring data cannot be realized. In addition, the dynamic detection of parameters of the dialysis machine is not performed in the simulated operation, so that the detection process lacks accuracy and safety.
In summary, how to accurately detect parameters of dialysis machines used in clinical dialysis in hospitals and dialysis centers is a problem to be solved by those skilled in the art.
