在临床实践中，出血点（HS）的检查仍然很困难。在本文中，我们描述了一种远程控制胶囊 (RCC) 微系统，该系统具有基于颜色的自动化传感器，用于识别和定位胃肠道 (GI) 的 HS。检测传感器的体外测试表明，当MIF中Hb浓度高于0.05μg/ml时，它能够区分含有和不含血红蛋白（Hb）的模拟肠液（MIF）。因此，该 RCC 系统能够检测 HS 在胃肠道中相对准确的位置。
In clinical practice, examination of the hemorrhagic spot (HS) remains difficult. In this paper, we describe a remote controlled capsule (RCC) micro-system with an automated, color-based sensor to identify and localize the HS of the gastrointestinal (GI) tract. In vitro testing of the detecting sensor demonstrated that it was capable of discriminating mimetic intestinal fluid (MIF) with and without the hemoglobin (Hb) when the concentration of Hb in MIF was above 0.05 g/ml. Therefore, this RCC system is able to detect the relatively accurate location of the HS in the GI tract.
