Bioelectrical impedance based urge incontinence recognition method

Abstract

The invention discloses a bioelectrical impedance based urge incontinence recognition method comprising the following steps of: calculating an electrical impedance signal of the bladder by using a bioelectrical impedance measuring device, carrying out analog-to-digital conversion and digital filtration on the electrical impedance signal, and then, sending the electrical impedance signal to a host computer; carrying out down-sampling treatment on the electrical impedance signal by the host computer by using a time interval prolonging method to obtain data values of a plurality of sampling points, fitting an electrical impedance amplitude curve, and extracting a characteristic parameter of the electrical impedance amplitude curve; and if the host computer judges that the characteristic parameter of the electrical impedance amplitude curve accords with a reference model, judging that a patient has the symptom of urge incontinence by the host computer, and sending an alarm signal. The bioelectrical impedance based urge incontinence recognition method disclosed by the invention can be used for realizing the noninvasive monitoring for the urge incontinence through establishing the reference model for detecting and judging the urge incontinence, and has the advantages of no invasion, on injury, convenience for detection and low cost.

Description

technical field [0001] The invention relates to the technical field of urinary incontinence detection, in particular to a method for identifying urge urinary incontinence based on bioelectrical impedance. Background technique [0002] Urinary incontinence is the loss of self-control of urination due to bladder sphincter damage or nerve dysfunction, causing urine to flow out involuntarily; and urge urinary incontinence can be caused by strong local stimuli such as partial upper motor neuron lesions or acute cystitis, The patient has very severe symptoms of urinary frequency and urgency, and urinary incontinence occurs due to the strong uninhibited contraction of the detrusor muscle. Usually secondary to a serious infection of the bladder. For patients with urge urinary incontinence, it is necessary to detect the symptoms of urge urinary incontinence in a timely and effective manner, so that the patients can seek medical treatment in time, formulate effective treatment and ev...

Problems solved by technology

[0003] At present, when examining patients' urgency urinary incontinence clinically, urodynamic detectors are often used for testing, but the equipment is bulky, complicated to operate, and requires invasive examination of patients. In addition to being inconvenient to carry around, It also causes great harm to patients

The prior art proposes a portable bladder urine volume detection device, which measures the electrical impedance amplitude, phase angle, real part, and imaginary part of the human tissue obtained by detecting the bioelectrical impedance of the sick part of the body, and through these The parameters of the equivalent circuit model of human tissue derived from the relevant parameters are used to judge whether the urinary bladder volume is within the safe range or whether the accumulated urine is exhausted, but the device fails to perform quantitative or qualitative detection of the human body characteristics of urge urinary incontinence , so it is not possible to detect whether the subject is a patient with urge urinary incontinence in time or to detect in real time whether the patient has urge urinary incontinence
