UMAG magnets used in Ventilator
NdFeB Permanent Magnets
In 2020, the CPAP devices are widely used to support patients affected by Covid-19. Ventilator is a crucial medical equipment which enables to treat respiratory failure, reduce complication and prolong patient‘s life.
Ventilator Magnet
Exhalation valve is a necessary component of the ventilator. Most of current exhalation valves are utilizes voice coil motor to drive the diaphragm to do linear displacement and this displacement will change the throttle area of fluid channel to dominate the on-off and flow rate, thus inhale and exhale can be controlled. Ventilator magnet is essentially a voice coil motor magnet. The voice coil motor in the exhalation of ventilator is composed of a ventilator magnet situated within a moving coil and all of two are inside of a ferromagnetic cylinder. Coil will be magnetized when current run through the coil and repels against the magnets, thus producing an in and out motion.
UMAG is now supplying NdFeB magnets to one of famous ventilator manufacturer, their equipments are widely used for patients treament in all of world.
