COVID-19检测是大流行控制的基石。如果操作不当，鼻咽拭子采集可能会很痛苦，分析前样本采集错误可能导致假阴性结果。我们的目标是开发一个现实的和容易获得的合成模拟鼻咽拭子采集。鼻咽拭子采集模拟器通过不同的开发步骤设计：分割，计算机辅助设计（CAD）和3D打印。该模型是使用PolyJet技术3D打印的，该技术允许使用硬材料和软材料进行多材料打印。模拟器在靠近鼻中隔的鼻旁平面中分裂，以便更好地可视化和理解鼻腔标志。该模型能够模拟不同结构元素的柔软度和纹理。模拟器允许用户进行逼真的鼻咽拭子采集。鼻咽后壁上的彩色垫为用户提供实时反馈。模拟器还允许不正确的拭子插入，这从培训角度来看具有明显的益处。用于打印的全面3D文件和制造模拟器的完整说明可通过开放访问链接在线免费获得。 在COVID-19大流行的背景下，我们开发了一种鼻咽拭子采集模拟器，可通过开放访问链接通过3D打印生产，并提供完整的操作说明。
Testing for COVID-19 is a cornerstone of pandemic control. If conducted inappropriately, nasopharyngeal swab collection can be painful and preanalytical sample collection errors may lead to false negative results. Our objective was to develop a realistic and easily available synthetic simulator for nasopharyngeal swab collection. The nasopharyngeal swab collection simulator was designed through different development steps: segmentation, computer-aided design (CAD), and 3D printing. The model was 3D printed using PolyJet technology, which allows multi-material printing using hard and soft materials. The simulator splits in the parasagittal plane close to the septum to allow better visualization and understanding of nasal cavity landmarks. The model is able to simulate the softness and texture of different structural elements. The simulator allows the user to conduct realistic nasopharyngeal swab collection. A colored pad on the posterior wall of the nasopharynx provides real-time feedback to the user. The simulator also permits incorrect swab insertion, which is of obvious benefit from a training perspective. Comprehensive 3D files for printing and full instructions for manufacturing the simulator is freely available online via an open access link. In the context of the COVID-19 pandemic, we developed a nasopharyngeal swab collection simulator which can be produced by 3D printing via an open access link, which offers complete operating instructions.
