The COVID-19 pandemic has caused an overload on the health care system on a global scale. Because the disease affects the respiratory system, patients may require ventilator equipment for breathing, and consequently, numerous tracheal intubations have been performed. The video laryngoscope is a medical device that aids this procedure. It is used by anesthesiologists to visualize the anatomical structures of the larynx during tube insertion. Unfortunately, many hospitals worldwide are unable to afford sufficient units of this medical device. To satisfy the high demand, low-cost alternatives employing three-dimensional (3D) printing techniques have been developed for health care professional's use. With the intention of ensuring the efficiency, reproducibility, and security of the 3D-printed laryngoscope, this article presents a novel model with versions for pediatric and adult use, which was developed under the supervision of a medical team. The mechanical performance of 3D-printed prototypes (of the proposed models) was evaluated using mechanical assays, and the results indicated a satisfactory safety factor.

三维印刷喉镜成为对抗 COVID-19 的盟友

COVID-19 大流行已导致全球范围内的医疗保健系统超负荷。由于该疾病影响呼吸系统，患者可能需要呼吸机来呼吸，因此需要进行多次气管插管。视频喉镜是一种辅助此手术的医疗设备。麻醉师使用它在管插入过程中可视化喉部的解剖结构。不幸的是，世界各地的许多医院无法负担足够的这种医疗设备。为了满足高需求，采用三维 (3D) 打印技术的低成本替代品已被开发出来供医疗保健专业人员使用。为了确保 3D 打印喉镜的​​效率、可重复性和安全性，本文提出了一种在医疗团队的监督下开发的新型模型，具有适合儿童和成人使用的版本。使用机械测定评估了 3D 打印原型（拟议模型）的机械性能，结果表明具有令人满意的安全系数。
