Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035]The present invention can be obtained through the experimental process, the change process of the urine volume in the bladder has a strong correlation with the impedance amplitude, and the biggest problem encountered in the measurement of the bioelectrical impedance of the bladder is the influence of the respiratory impedance and whether the bladder enters an empty state. Since the experimental model parameters are based on the urine accumulation process of bladder emptying, the condition of bladder emptying needs to be ensured in the experiment. The process with the largest impedance is taken as its similarity condition, because this condition can ensure the unity of the test state of the tester under different circumstances; then, the moment of the maxim...

Abstract

The invention discloses a non-invasive type urination alarming device based on bioelectrical impedance and a monitoring method. The method includes: a, acquiring human body electrical impedance data via a testing electrode worn at a position, corresponding to the bladder, of the lower portion of the lower abdomen of a patient and realizing filtering, noise reduction and analog to digital conversion; b, searching the maximum point of the data impedance amplitude in an acquisition process in real time; c, dividing a sampling data curve into sections according to sampling rate and physiological characteristics, carrying out fitting operation for sampling data of each section within set time, building a data multi-item type fitting model in a unified manner, and calculating the fitting coefficient of each section of the sampling curve after fitting; and d, building a fitting curve, calculating features of the fitting curve, finally judging whether the urine quantity of the bladder of the patient reaches an alarming point or not according to the features of the fitting curve and the change degree of the fitting coefficients, automatically alarming if the urine quantity of the bladder of the patient reaches the alarming point, and then prompting the patient to urinate in time. The non-invasive type urination alarming device is safer and more convenient in operation, good in anti-interference effect and capable of clearly and accurately displaying and measuring data.

Description

[0001] The present invention requires the patent title of "Non-Invasive Urine Alarm Device and Monitoring Method Based on Bioelectrical Impedance" which was previously applied to the Chinese Patent Office. The application date is June 13, 2011, and the application number is 201110156918.1. The applicant is Guangzhou Ande Biotechnology Co., Ltd. technical field [0002] The invention relates to a medical detection device, in particular to a bioelectrical impedance-based non-invasive urination alarm device and a monitoring method. Background technique [0003] At present, the method for detecting the condition of a patient's bladder mostly adopts ultrasonic technology, and its ultrasonic instrument is bulky, expensive, and inconvenient to carry around. For patients suffering from nephritis, cystitis, urinary incontinence, and patients who cannot sense the bladder urine volume, it is necessary to monitor the bladder urine volume in real time and remind the patient to urinate in...
