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

Abstract

The invention discloses a vesica urinaria urine accumulation real-time monitoring method based on bioelectrical impedance. The method comprises collecting human body electrical impedance data through a testing electrode which is worn on a tested portion of a patient, and according to collected human body electrical impedance data, extracting a time domain feature of the human body electrical impedance data. The time domain feature at least comprises current electrical impedance value, current electrical impedance minimum differential value and current electrical impedance absolute value integral value. Vesica urinaria urine accumulation amount of the patient is calculated based on the time domain feature, the calculated vesica urinaria urine accumulation amount is compared with urine amount threshold value which is set for different patients in advance, and when the vesica urinaria urine accumulation amount achieves and / or exceeds the urine amount threshold value, an alarm is sent. The vesica urinaria urine accumulation real-time monitoring method can precisely forecast urine accumulation amount in the process of urine accumulation, and improves real-time monitoring precision of the vesica urinaria urine accumulation. The invention further discloses a vesica urinaria urine accumulation real-time monitoring device based on the bioelectrical impedance.

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 bladder accumulation 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, 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 bladder urine output monitoring methods cannot meet the abo...

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.
