Vesica urinaria urine accumulation real-time monitoring method and device based on bioelectrical impedance

Abstract

A vesica urinaria urine accumulation real-time monitoring method and device based on bioelectrical impedance. The method comprises the steps of: collecting human body electrical impedance data through a testing electrode which is worn on a tested portion of a patient; extracting a time domain feature of the human body electrical impedance data according to the collected human body electrical impedance data, wherein the time domain feature at least comprises a current electrical impedance value, a current electrical impedance minimum differential value, and a current electrical impedance absolute value integral value; calculating a vesica urinaria urine accumulation amount of the patient based on the time domain feature; comparing the calculated vesica urinaria urine accumulation amount with a urine amount threshold which is preset for different patients; and sending an alarm when the vesica urinaria urine accumulation amount reaches and / or exceeds the urine amount threshold. The vesica urinaria urine accumulation real-time monitoring method and device can accurately predict the urine accumulation amount in the process of vesica urinaria urine accumulation, and improve real-time monitoring precision of vesica urinaria urine accumulation.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a method and device for real-time monitoring of urinary cysts based on bioelectrical impedance. Background technique [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, and it is impossible to grasp the urine volume of patients in time. For patients with urinary incontinence, cystitis, spinal cord injury, etc., 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 urination, excessive urination, or incomplete urination. Remote monitoring is achieved through wired (or wireless) communication methods, and the current bladder and urine volume monitoring methods cannot meet the above requirements. [0003] Bioelectrical impedance technology utilizes t...

AI Technical Summary

Problems solved by technology

However, considering that the human bladder organ is an extremely complex adaptive system, the conductivity of urine is constantly changing during the process of bladder accumulation, and it has been confirmed by literature that in the stage before bladder accumulation (especially half an hour before measurement) , the contact resistance of the electrode rises more obviously

Therefore, it can be seen that the prediction of urine volume based on the drop in impedance (threshold value) must have the problem of low accuracy and large interference; at the same time, the existing technical research has not considered the evaluation of the autonomic nerve regulation function of patients with urinary insufficiency.
