DC Motor Solution for Breathing Apparatus

With the pandemic severely spreading around the world, countries at the height of the epidemic, except for the need for masks and protective clothing, are in urgent need of a medical device: breathing apparatus.

What is Breathing Apparatus?

In modern clinical medicine, among many medical devices are indispensable instruments to save lives, such as respirators or ventilators. As an effective means to replace ventilation, the ventilator has been widely used in clinical practice for various diseases occupying a vital position. The ventilator produces positive pressure during the inhalation phase, and the patient will push the gas into the lungs. When the pressure rises to a certain level, the breathing machine stops the supply of air, and the exhalation valve opens successively. The patient’s chest and lungs will collapse passively, producing exhalation.

Breathing Apparatus

We can divide the clinical application of ventilators into two categories: the first type is based on mainly respiratory diseases, including pulmonary infection, non-distension of the lung, asthma, and pulmonary edema, which affect pulmonary gas exchange function. At this point, ventilator treatment mainly improves the pulmonary gas exchange, increases the oxygen concentration in the blood, and removes carbon dioxide. The second one is mainly used in surgical operations, which is conducive to the recovery of anesthesia, the maintenance of normal respiratory function, the reduction of respiratory muscle movement, and the reduction of oxygen consumption.


A ventilator is a device that can replace, control or change normal physiological respiration, increase pulmonary ventilation, improve respiratory function, reduce respiratory energy consumption, and save cardiac reserve capacity. It can also prevent and treat respiratory failure and save the lives of patients.

How the Respirator Motor Work

The motor is the core of the ventilator control system. When the ventilator is working in good condition, sensors “sense” changes in respiratory mechanics and control the Voltage and Speed of the DC motor to cause the ventilator relief valve to close. Once the air supply is interrupted, the negative pressure of the pipe resulting from the patient’s inhalation is controlled by the motor driving the valve plate while the motor gearbox regulates the air intake. The air is piped to ensure the patient’s supply of air and avoid suffocation.


DC motors are commonly used in safety devices. When either of the two gases is used up or no longer meets the requirements of use, the motor control valve from the other gas immediately and automatically switches to maintain the gas supply. The latest motor (RS-555PHVC2-3262RD) developed and manufactured by Kinmore Motor enables the ventilator to meet customer’s needs. Customized motor technical parameter service is adopted to reduce the loss, improve product quality, and reduce customer purchase costs.
