目前还没有理想的诊断肠道出血疾病的方法,尤其是小肠出血。研究了一种基于颜色识别的智能肠出血检测胶囊系统。吞咽胶囊后,出血检测模块(包含吸收肠液时变色的色敏吸附膜)用于识别肠道出血特征。根据胶片颜色的H和S值的范围,可以应用色调-饱和度-光颜色空间方法来检测渗色。一旦识别出出血特征,立即激活无线传输模块,向外界发出报警信号;体外模块接收信号并发出报警。整个胶囊系统的平均功耗估计约为2.1mW。该系统简单、可靠、有效,为临床诊断肠道出血性疾病提供了一种新的方法。
There are no ideal means for the diagnosis of intestinal bleeding diseases as of now, particularly in the small intestine. This study investigated an intelligent intestinal bleeding detection capsule system based on color recognition. After the capsule is swallowed, the bleeding detection module (containing a color-sensitive adsorptive film that changes color when absorbing intestinal juice,) is used to identify intestinal bleeding features. A hue-saturation-light color space method can be applied to detect bleeding according to the range of H and S values of the film color. Once bleeding features are recognized, a wireless transmission module is activated immediately to send an alarm signal to the outside; an in vitro module receives the signal and sends an alarm. The average power consumption of the entire capsule system is estimated to be about 2.1mW. Owing to its simplicity, reliability, and effectiveness, this system represents a new approach to the clinical diagnosis of intestinal bleeding diseases.
