我们采用CT扫描衍生的3D打印肺模型和可调谐气流剖面,提出一种高通量体外方法,用于在叶位水平上量化区域肺沉积。

该方案有可能通过实现区域沉积的临床前预测来推动新的靶向肺部治疗药物的开发。该技术结合了解剖学上准确的肺部模型,从患者的 CT 扫描中 3D 打印出来,以快速生成有关潜在治疗效果的个性化预测结果。该技术可用于开发靶向疗法,以最大限度地减少以区域阻塞为特征的疾病(如肺癌或 COPD)的脱靶效应。

按照制造商的说明打印实验组件并完成后处理后,根据制造商的规格,在对流烘箱中对部件进行热固化 8 小时之前,用纯度至少为 99% 的异丙醇仔细清洗用软树脂打印的部件,以去除多余的未固化树脂。然后,用酒精清洗用硬树脂打印的部件,以去除多余的未固化树脂,并在紫外线烘箱中每面固化一分钟。对于凸轮出口盖组件,将椭圆形倒钩管连接底座的一端插入盖子,然后小心地将柔性盖拉伸到椭圆形底座的另一端,特别注意不要使薄底座破裂,并使喷嘴从盖底座的开口中伸出。
