Abstract

The invention discloses an online monitoring method and system of creatinine content in hemodialysis dialysate. The method comprises the steps of preparing hemodialysis dialysate samples with different creatinine contents in sample cups, performing spectra collection on the hemodialysis dialysate samples by using a Fourier transform near infrared spectrometer, building a near infrared spectroscopy-based quantitative identification model of creatinine content in hemodialysis dialysate, sending the identification model to a central processing unit, performing near infrared spectra collection ondialysate from the outlet of a hemodialysis dialyzer by using an online monitoring probe, sending near infrared spectrum of creatinine content in the collected dialysate from the outlet of the dialyzer to the central processing unit, comparing, by the central processing unit, quantitative identification models of creatinine content in two dialysates, and if the content including a detection liquidexceeds a preset value, sending an alarm instruction to an alarm by the central processing unit. The method effectively reduces man-made errors and system errors, the model has a high accuracy rate,and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical testing and measurement, in particular to an online monitoring method and system for creatinine content in hemodialysis fluid. Background technique [0002] At present, blood purification is widely required in clinical treatment. Taking dialysis treatment of kidney disease as an example, there are about 2 million patients with end-stage renal disease in my country, 400,000 of whom are receiving hemodialysis treatment, which is increasing at a rate of more than 10% every year. Patients have a great demand for dialysis treatment. [0003] Hemodialysis uses the principle of semi-permeable membrane to introduce the patient's blood and dialysate into the inner and outer sides of the dialyzer at the same time. With the help of the solute gradient, osmotic gradient and diffusivity on both sides of the membrane, through diffusion, convection, and removal of toxins, etc., Through this method, excess water...
