Simulación de una cabina segura adaptable en camillas para atender a pacientes con enfermedades infectocontagiosas

Abstract

This work describes the design and manufacture of a prototype of a safe cabin for patient care, in order to protect the lives of health personnel and the need to adapt to the Coronavirus crisis in a short time, it has been embodied this solution. For the development of this design, it was considered measures of existing stretchers on the market in order to have actual measurements that were used to design and simulate the prototype, for the final design the recommendations of the doctors were taken into account. The new cabinet is a small revolution for patient care, the design and assembly was done in Autodesk Inventor software and the simulation in Xflow software. It was considered two stages : In the first stage, a totally closed cabin was simulated, this to understand the behavior of the fluid under real conditions and parameters , where it was obtained a maximum speed of 13.25 m/s in a time of 0.26 seconds. In the second stage, the open cabin was simulated where the distance that the particles travel in an outdoor environment is visualized, obtaining a distance of 0.7 m at a time 0.5 seconds, so the same maximum speed obtained was 14.4 m/s at 0.25 s considering the vertical position of the manikin and that the fluid hits the walls of the cabin. The flow velocity from the mouth to the closest part to the protection cabinet whose distance is 157 mm, the sneeze 1 was simulated in 0.3 seconds and the sneeze 2 lasted 0.5 seconds, resulting in average speed in the closed cabinet ranging from 3. 31 m/s up to 13. 25 m/s, while in the open car the average speed ranges from 3.49 m / s to 13.96 m / s. But the number of oscillated drops varied greatly. The results obtained were compared with other previous studies related to the behavior of a sneeze, obtaining similar results to those studies and whose average speed ranged is between 12 and 15 m/s.
