Description

Intelligent sensing-based urination difficulty and urinary incontinence integrated monitoring and diagnosis system Technical Field The invention relates to the technical field of medical monitoring, in particular to an intelligent sensing-based urination difficulty and urinary incontinence integrated monitoring and diagnosing system. Background Urination disorders are a common urinary system disorder involving multiple physiological processes such as urine storage from the bladder, urination and discharge to the urethra. With aging population and changes in lifestyle, the occurrence rate of urination difficulty and urinary incontinence gradually increases, and the quality of life of patients is significantly affected. However, despite the progress made in the relevant diagnostic arts in modern medicine, accurate diagnosis of urination disorders still faces many challenges. Dysuria and urinary incontinence are key technical problems in relation to whether bladder emptying is complete, detrusor contractility, assessment of bladder pressure, measurement of urine flow rate, assessment of urethral and bladder outlet obstruction. First, whether bladder emptying is a complete basis for diagnosing dysuria. The normal functioning of bladder function depends not only on its ability to store urine, but also requires complete emptying during urination. Traditionally, residual urine volume (PVR) assessment is used to measure whether urination is complete, but this method can only provide static results, lacks dynamic and real-time bladder emptying monitoring, and has difficulty accurately reflecting the urination function status of the bladder. Therefore, how to accurately evaluate whether bladder emptying is complete in real time through innovative techniques becomes a big challenge in current diagnosis. Second, detrusor contractile function is a critical factor in the bladder urination process. Normal contraction of detrusor is a precondition for maintaining smooth urination, but the contraction intensity and coordination of detrusor are often affected by various factors, and the existing ultrasonic and electromyography monitoring technology cannot accurately measure the contraction pattern of detrusor and the relation between detrusor and urination, so that a plurality of causes of difficult urination cannot be identified and treated in time, and therefore, how to accurately evaluate the contraction function of detrusor by combining high-resolution dynamic ultrasonic and electromyography monitoring becomes a technical problem to be solved urgently. Bladder pressure is another important factor affecting urinary incontinence. The pressure change of the bladder directly reflects its dynamic capacity to store and urinate. Traditional bladder pressure assessment often relies on invasive methods such as urodynamic examination, which not only is inconvenient for clinical widespread use, but may also cause discomfort to the patient. Therefore, how to monitor the pressure change of the bladder in real time by combining the noninvasive ultrasonic technology with the pressure sensor so as to evaluate the bladder compliance and the detrusor function is a problem to be solved in the diagnosis of urination disorder. In addition, measurement of the urine flow rate is of great importance in diagnosis of urination disorders, but accuracy is often affected by factors such as fluctuation of the urine flow, instability of the urine flow speed and the like, and it is difficult for the existing ultrasonic technology to accurately measure the urine flow rate under the condition of low flow rate or irregular flow rate, so that accurate diagnosis cannot be obtained in many cases. Finally, urinary and bladder outlet obstruction are often the source of urination disorders, but how to accurately assess the location, type and effect of obstruction on urination remains a difficulty in clinical practice. Although the traditional imaging examination can provide certain morphological information, the traditional imaging examination has great limitation in the aspects of dynamic monitoring and real-time evaluation of obstruction conditions. Therefore, how to use the ultrasonic radiography technology and the pressure sensor to monitor the pressure change and the shape change of the urethra and the bladder outlet in real time, and help to evaluate whether the obstruction exists or not is a key point for solving the problem of urination disorder.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: Urination difficulty and urinary incontinence integrated monitoring and diagnosing system based on intelligent sensing comprises: the bladder emptying evaluation module is used for tracking the shape and capacity c
