Description

带 CCD的红外线热扫描胶囊小肠镜系统 技术领域
本发明涉及医疗器械， 具体是一种可以进入小肠进行检查的医用胶囊小肠镜系统。 背景技术
胶囊内窥镜全称为 "智能胶囊消化道内镜系统" ， 又称 "医用无线内镜" 。 原理是受检 者通过口服内置摄像与信号传输装置的智能胶囊， 借助消化道蠕动使之在消化道内运动并拍 摄图像， 医生利用体外的图像记录仪和影像工作站， 了解受检者的整个消化道情况， 从而对 其病情做出诊断。 胶囊内镜具有检查方便、 无创伤、 无导线、 无痛苦、 无交叉感染、 不影响 患者的正常工作等优点， 扩展了消化道检查的视野， 克服了传统的插入式内镜所具有的耐受 性差、不适用于年老体弱和病情危重等缺陷， 是消化道疾病尤其是小肠疾病诊断的首选方法。
美国专利 5， 604， 531提出了一种口服胶囊式的无线电内窥镜系统， 该消化道照相胶囊由 光学成像、 照相和图像传输三部分组成， 当病人吞下该胶囊内窥镜后， 胶囊中的微型摄像机 能将拍摄的胃肠内部清晰图像通过信号发送给体外的图像记录装置， 录制完毕后， 该图像记 录装置中的影像被提取出来进行分析， 从而了解胃肠疾患。 该法具有操作简单、 检查方便、 无创伤、 无痛苦、 无交叉感染等优点， 但也存在其不足之处： 其内核是电子 CCD (电荷耦合 元件） 光学成像系统， 由于受到能量、 储存和体积等制约， 胶囊小肠镜的图像分辨率较低， 而且寿命较短， 不能很好地满足医生做诊断的要求。
医用红外线成像来源于军工技术， 使用已有 40多年的历史。红外线热扫描通过检测人体 表面的热辐射强度来诊断疾病。 人体是一个新陈代谢基本平衡的热辐射体， 如果某一区域的 新陈代谢出现异常的活跃或减低， 则表示该部位发生了病理性病变。 热成像技术通过对人体 表面进行扫描， 获得人体表面区域的热辐射强度分布图， 并使用温度值对热辐射强度加以量 化， 热辐射强度越高， 温度值越高， 同时在电脑屏幕上用颜色来显示不同温度值。 由于细胞 病变部位的热辐射非高即低， 图的颜色就出现异常， 由此可为诊病提供依据。 红外线热扫描 成像系统具有以下优点： 由于在扫描过程中只接收人体细胞代谢中产生的热辐射， 对人体无 辐射、 无损伤， 还能对人体各部位快速断层扫描、 彩色成像， 具有多点、 多区域、 断层扫描 等多种检测功能， 能够对多种疾病进行早期定性诊断， 是对 B超、 CT、 MR等其他形态学诊断 方法的重要补充。 发明内容
