CPAP Machine Motor

As the world is struck by the pandemic, there’s been a sharp increase in the need for CPAP machines to treat patients with difficulty in breathing. ZHAOWEI can provide gear motor solutions for not only CPAP machines, but also other medical devices…

What is CPAP?

CPAP, the abbreviation for continuous positive airway pressure, is a form of positive airway pressure (PAP) ventilation. CPAP therapy is widely used in the treatment of obstructive sleep apnea (OSA), and pre-term infants whose lungs have not fully developed to supply enough oxygen and support breathing.

The CPAP machine is basically a small box that has a motorized fan inside. The fan, driven by a gear motor, quietly draws air from the room through a filter and gently pressurizes it to send the air to users. Another key component is the mask, which consists of frame, cushion, and headgear. There is a tube to connect the motor and mask, passing the air through a heated humidifier and then delivering it to the mask interface.
