Background & Challenge
The world of medicine is an ever-changing landscape since COVID-19 pandemic. As technology changes, medical device manufacturers are turning to lighter, smaller components that can improve the reliability, longevity and performance in the life-saving products and applications. One example is the increasing use of voice coil motors to control the valves in ventilators for patients who have difficulty in breathing on their own.
The construction of a ventilator is straightforward. Requiring only a few components, ventilator machine has traditionally used solenoid valves to control the flow of air. Now, after strictly testing, it becomes clear that the voice coil motor outperforms solenoids in every aspect. High precision, acceleration and lightweight design have come together to revolutionise the way ventilators are made.
With the solenoid valve, you are given an on/off device that requires a spring to activate bi-directional movement, in contrast to the voice coil motor[...]
