As a result of the pandemic, cases requiring endotracheal intubation have increased to support breathing through mechanical ventilation; this procedure is necessary when a patient cannot breathe on their own due to respiratory failure. For it, the laryngoscope is used. Even when using a laryngoscope, it is possible to injure the patient due to poor visibility at intubation. As a solution, some video-laryngoscopes present many advantages, such as reducing injuries, lowering the number of attempts to secure the airway and the image’s quality, and easy recognition of laryngeal structures. However, this type of device is not accessible to many health institutions due to the price. Therefore, this study proposes the design of a video-laryngoscope in the Computer-Aided-Design (CAD) software and constructed by additive manufacturing. For this design, the identification of the needs of the medical personnel in the anesthesiology and emergency medicine departments from the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (INCMNSZ) was taken into account. The design specifications provided by the users were used to create a proposal solution at the conceptual design level. The material and camera for the prototype instrumentation are presented with the model’s geometric parameters. Subsequently, virtual modeling of the device was carried out, and rapid prototypes were built to validate the performance of the design proposal. The final device was constructed by Selective Laser Sintering (SLS) using Nylon 12 as a construction material. Finally, the device was evaluated using airway simulators with the support of medical specialists to determine its functionality. |
