A-mode ultrasound based urination monitoring and alarming device and method

Abstract

The invention provides an A-mode ultrasound based urination monitoring and alarming device and method. The device comprises an A-mode ultrasonic probe with angle adjustable, an A-mode ultrasonic transceiving module, an ultrasonic signal processing module and an alarm module, wherein the A-mode ultrasonic transceiving module comprises a pulse signal generator, an ultrasonic transceiving control module and a signal filtering and amplifying circuit; and the ultrasonic signal processing module comprises a signal analyzing and processing module and an A / D data acquiring circuit. The device and the method have the following advantages: the device is simple, is convenient to carry, is powered with batteries, can realize continuous monitoring of urine volume in the bladder and has strong usability; and the device signal analyzing and processing procedure in the method is simple and is lower in cost.

Description

technical field [0001] The invention belongs to the technical field of medical detection, and relates to an A-type ultrasound-based urination monitoring and alarming device and a monitoring and alarming method. Background technique [0002] For normal people, when the bladder is full to a certain extent, there will be a urge to urinate from time to time, prompting people to urinate. For some patients with mental retardation, patients with spinal cord injury, some elderly people and infants, these people either do not have the urge to urinate, or they cannot control urination due to neurodevelopmental reasons. Many of these patients with urinary incontinence need special help Nursing, the workload of the nursing staff is huge, by monitoring the bladder in real time and implementing the urination warning device, the work intensity of the nursing staff is greatly reduced. In addition, the urination warning device can also promote the treatment of urinary incontinence caused by...

Problems solved by technology

[0003] A commonly used nursing method in clinical practice is urinary catheterization, that is, a catheter is inserted into the bladder to drain urine, but this method is invasive and may lead to secondary infection of the urinary tract

At present, several methods, technologies and instruments for detecting bladder urine volume have been published, such as B-ultrasound detection method based on imaging to estimate urine volume using formulas, portable urine volume detector using three-dimensional volume calculation method to calculate urine volume, etc., but These detection methods or detectors are not suitable for continuous urine volume detection, nor do they have the function of early warning of urination

However, the disclosed method of urination warning by calculating bladder urine volume needs to use multiple ultrasonic probes or scan the entire bladder by probes to calculate the urine volume. The system is too complicated and the cost is very high.
