Diseño de un generador de flujo para un dispositivo de asistencia respiratoria de presión positiva de dos niveles (BIPAP)

Abstract

Nowadays, the need for medical equipment for the treatment of respiratory diseases is growing more and more and the state’s expenditure for the acquisition of the same is very large, so the objective of designing the flow generator of the respiratory assistance devices such as BiPAP; opens the way to be able to manufacture ours at national level thus reducing the budget for the acquisition of these. The Technical Project focused on the design of the generator under conventional parameters of operation, this implies the development of the flow system and the control system in charge of supplying positive pressure with a driver of speed variation of the centrifugal ventilator together with a programmable control board, for the configuration of the treatment that the patient needs; the selection of the manufacturing materials and elements necessary for its operation was carried out. The behavior of the flow generator was analyzed by means of a multiphysical computational analysis, this was very useful since it allowed us to establish the operating range of the device, for the development of the manufacturing and assembly process. As a result, a virtual mock-up was created with all the information about the design process, including all the parameters contemplated in the design process of the flow generator, simulation results, manufacturing drawings and assembly drawings. Resulting in a solid project that is ready to be put into test operation.
