Low-load bladder urine-volume real-time monitoring and automatic alarming method

Abstract

A low-load bladder urine-volume real-time monitoring and automatic alarming method comprises the following steps of (1) closely attaching a plurality of test electrodes onto a tested part of a patient and measuring an electric impedance value of a bladder in real time through a biological electric impedance measuring device according to a biological impedance technology; (2) selecting appropriate parameters through a digital filter algorithm, removing an interference signal and improving the signal-to-noise ratio of the electric impedance; updating the maximal electric impedance value in real time, and calculating an impedance threshold value and a variation rate of the impedance threshold value; and (3) establishing an expert diagnosis system through medical knowledge and clinical test experience, fuzzing the impedance threshold value and the variation rate of the threshold value, and establishing a fuzzy rule; and realizing the automatic urine discharging alarm according to the judgment of the fuzzy rule so as to remind the patient to urinate in time or notify the medical personnel. Due to the adoption of the method, the urine volume of the bladder can be accurately and dynamically predicted in real time, an alarm for urination can be issued, the patient is reminded of urinating in real time or the state of an illness can be remotely monitored through a wireless network, more safety and convenience in operation can be realized, and the interference resistance is strong.

Description

technical field [0001] The invention relates to a method for real-time monitoring of bladder urine volume, in particular to a method for real-time monitoring of bladder urine volume under low load and an automatic urination alarm method based on bioelectrical impedance. technical background [0002] At present, most of the detection methods of bladder condition use ultrasonic, pressure, displacement and other technical means, all of which are static monitoring methods, which cannot grasp the patient's urine volume in time. For patients with urinary incontinence, cystitis, spinal cord injury and other patients who lack the urge to urinate, it is necessary to monitor the bladder urine volume in real time and remind the patient to urinate in time to prevent complications such as excessive urine accumulation, frequent urination or incomplete urination; at the same time, it can also Remote monitoring is realized by wired (or wireless) communication methods, and the current bladde...

Problems solved by technology

However, considering that the human bladder organ is an extremely complex adaptive system, the mathematical model between its electrical impedance change and urine volume change is extremely complex, and there are obvious individual and spatiotemporal differences, which further complicate the model, so , in the prior art, a simple linear relationship is used to predict urine output, and there must be a huge error
