Videolaryngoscopes have been designed to improve the success rate of tracheal intubation on the first attempt; however, their high cost, especially in low- and middle-income countries, is a major disadvantage. Considering the clinical importance of this device, the Engineering School in partnership with the Anesthesiology Department developed a videolaryngoscope using three-dimensional (3D) printing technology at a more affordable cost. The methodology consisted of three stages: prospecting, modeling and prototyping, and realistic simulation on airway mannequins. The primary objective was to describe the creation and development process of the prototypes. The secondary objective was to determine the final production cost. This was an applied project utilizing an exploratory and descriptive approach. The study was developed during the COVID-19 pandemic, between May 2020 and June 2021, at the School of Engineering and in the realistic simulation room at the university hospital. Ten prototypes were produced before the final product, and they were subjected to strength and bending tests and evaluated on airway training mannequins to simulate the procedure conducted by anesthesiologists. As a result, we obtained a resistant, and low-cost device, named VLG3DUFF.
视频喉镜的设计目的是提高首次气管插管的成功率；然而，其高昂的成本，尤其是在低收入和中等收入国家，是一个主要缺点。考虑到该设备的临床重要性，工程学院与麻醉科合作，利用三维（3D）打印技术以更实惠的成本开发了一种视频喉镜。该方法包括三个阶段：勘探、建模与原型制作以及在气道模型上进行逼真模拟。主要目标是描述原型的创建和开发过程。次要目标是确定最终生产成本。这是一个采用探索性和描述性方法的应用项目。该研究于2020年5月至2021年6月在新冠疫情期间，于工程学院和大学医院的逼真模拟室开展。在最终产品之前制作了十个原型，并对其进行了强度和弯曲测试，并在气道训练模型上进行评估，以模拟麻醉医生进行的操作。结果，我们获得了一种耐用且低成本的设备，名为VLG3DUFF。
