Design and manufacture of ventilators

Abstract

A ventilator is a product that is being focused, researched, developed and manufactured on a large scale to serve the treatment of patients with respiratory difficulties as well as patients with COVID-19. With this topic, ventilators are designed and manufactured based on the operating principles of conventional ventilators, improved with some features to suit each user. Squeeze frequency may be varied to accommodate the common patient and patients with COVID-19. The mechanical design of the bag gripper arm is simulated based on the operation of the human hand. The squeeze force comes from two sides of the Ambu bag so it is not deformed much. It can control the speed of the bag, control the amount of gas to supply to the patient. Control circuits using Arduino can easily develop new functions.
