The collection capacity of common nasopharyngeal swabs and irregularities of medical personnel limit the accuracy of PCR testing. This study describes a newly designed 3D-printed swab that is combined with a 3D-printed cover to prevent the extraction of undesired nasal secretions. This swab improved the accuracy of PCR test results. The results of a series of experiments showed that, because of the mucus extraction effect, 3D-printed swabs can replace ordinary cotton swabs. The crisis of the worldwide medical supply shortage can be ameliorated to a certain extent by applying 3D printing technology.
普通鼻咽拭子的采集能力和医务人员的不规范操作限制了 PCR 检测的准确性。本研究描述了一种新设计的 3D 打印拭子，它与 3D 打印盖结合在一起，以防止提取不需要的鼻腔分泌物。这种拭子提高了 PCR 检测结果的准确性。一系列实验结果表明，由于粘液提取效果，3D 打印拭子可以替代普通棉签。通过应用 3D 打印技术，可以在一定程度上缓解全球医疗用品短缺的危机。
