According to Engineering News, an engineering team from the University of Johannesburg (UJ) has designed and developed a portable 3D-printed mechanical ventilator that has a customisable base plate to treat multiple patients.
The ventilator, named Aura Imprimere, which means “a breeze of air provided by printing”, also allows off-grid operations for up to one and a half hours should electricity supply be cut.
UJ Department of Mechanical Engineering Science head and project team leader Professor Tien-Chien Jen said the “unique 3D-printable ventilator” uses a microcontroller to control the operation of the two motors.
“By adjusting the speed and direction of rotation of the motors, it is possible to obtain a pressure-time profile that is suitable for the respiratory assistance of patients.
“Its components are also designed in such a way that it can be easily assembled, on site in cities, rural areas, or remote areas,” he added.
