INTRODUCCIÓN. Extensión de la ingeniería concurrente a entornos en los que se considera la sostenibilidad. OBJETIVO. Establece el marco conceptual y los cambios metodológicos que deben introducirse para su desarrollo. MÉTODO. La investigación se desarrolla bajo un enfoque mixto y bibliográfico. Se basa en el análisis de varios proyectos en entornos donde la sostenibilidad es esencial. RESULTADOS. Además de un marco conceptual para estos proyectos, el aspecto metodológico más destacado es la inclusión de una etapa previa en el ciclo de diseño de análisis del entorno. DISCUSIÓN Y CONCLUSIONES. Hoy día, la ingeniería concurrente, debe abarcar la sostenibilidad de los recursos naturales y de la propia vida humana.

This article shows the design of a device to automatize an Ambu Spur II manual respirator. The aim of this compassionate medicine device is to provide an emergency alternative to conventional electric respirators—which are in much shortage—during the present COVID-19 pandemic. To develop the device, the classical method of product design based on concurrent engineering has been employed. First, the specifications of the machine have been determined, including the function determining the air volume provided at every moment of the breathing cycle; second, an adequate compression mechanism has been designed; third, the control circuit of the motor has been determined, which can be operated via a touchscreen and which includes sensor feedback; fourth, the device has been materialized with readily available materials and market components, mostly of low cost; and fifth, the machine has been successfully tested, complying with sanitary regulations and operating within desirable ranges. The device has been already manufactured to supply respirators to several hospitals around the Catalan Autonomous Community in Spain, but can also be replicated in developing countries such as Ecuador.
