Real-time monitoring and automatic alarm method of low load bladder urine volume

Abstract

Disclosed is a method of real-time monitoring of low urine volume in the bladder and an automatic alarm, which includes the following steps: 1) tightly attaching multiple test electrodes to the test sites of a patient, and real-time monitoring of an electrical impedance value of the bladder with a bio-electrical impedance measurement device according to a bio-electrical impedance technique (101); 2) by means of a digital filter algorithm, selecting suitable parameters and removing interference signals to improve the signal-noise ratio of the electrical impedance, and real-time updating of the maximum value of the electrical impedance and calculating an impedance threshold value and change rate thereof (102); 3) according to medical knowledge and clinical experience, establishing an expert diagnostic system to approximately process the impedance threshold value and the change rate of the threshold value, deciding on an approximate rule and then effecting an automatic urination alarm according to the approximate rule so as to remind the patient of the need to urinate in time or to inform a medical worker (103). By employing this method, the urine volume in the bladder can be dynamically predicted accurately and in real time and a urination alarm is effected, so the patient can be reminded of the need to urinate in time, or the pathogenic conditions can be monitored remotely via a wireless network, which is more convenient and safer to operate and has a strong anti-interference capability.

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
