Hemodialysis dry weight intelligent assessment device

Abstract

The present invention provides an intelligent evaluation device for hemodialysis dry weight, which is used for evaluating the dry weight required by hemodialysis patients for hemodialysis. The linear model of the relationship between the point and the weight after differential dialysis, and based on the least square method to solve the optimal parameters of the linear model to form the overall trend model of the individual body weight of the hemodialysis patient; the local regression model construction department, based on the Gaussian kernel function method to obtain weight data set and perform local regression correction on the overall trend model of body weight to form a local weight regression model; the dry weight prediction department will input the current hemodialysis time point into the overall weight trend model and local regression model, and combine the body weight after dialysis The index average is used to obtain the predicted dry weight; and the dry weight adjustment unit adjusts the predicted dry weight according to the correction factor corresponding to the patient characteristics of the patient to obtain the dry weight of the patient to be hemodialysis.

Description

Technical field [0001] The present invention is in the field of medical devices, particularly, to a hemodialysis Dry Weight intelligent evaluation device. Background technique [0002] Hemodialysis as a primary means of end-stage renal solution can effectively remove excess water from the blood, metabolic wastes, correction of electrolyte and acid-base balance disorders, and finally to reach dry weight at the end of dialysis patients. Dry weight is the most important treatment parameters hemodialysis patients, representative of the load of maintenance hemodialysis patients suitable fluid state. Physicians often require hemodialysis patients analyzed for the state and adjust the amount of dialysis, hemodialysis patients in order to ensure the dry weight as close to the ideal dry weight. [0003] Refers to the lowest body weight over the dry weight after the hemodialysis patient can tolerate performed, due to the different actual physical condition of the patient and each patient o...

Problems solved by technology

However, this assessment requires special equipment, and its clinical use is limited because blood volume is affected by the regulation of intracellular and extracellular fluids and body position

[0009] Therefore, the above methods are difficult to accurately calculate the dry weight of the patient. During the hemodialysis treatment, it is based on the comprehensive consideration of the hemodialysis doctor based on the patient's clinical symptoms or signs, supplemented by biochemical or physical detection methods. Relying on the personal experience of hemodialysis physicians, experienced hemodialysis physicians are significantly more accurate in estimating dry weight of patients than general physicians

However, there is a shortage of professional medical teams in my country, and the level of hemodialysis centers is not balanced. Therefore, it is often difficult for patients to achieve the ideal dry weight in clinical hemodialysis treatment.
