At present, domestic ventilators and oxygen generators are relatively popular home medical equipment. Many people are confused about the difference between ventilator and oxygen generator. They regard the ventilator as an oxygen generator and mistakenly think that the ventilator can also produce oxygen. In fact, otherwise, ventilator and oxygen generator are two kinds of medical devices that are essentially different. So, what is the difference between a home ventilator and an oxygen generator?

The difference between home ventilator and oxygen generator is that they use different principles.

The principle of home ventilator: Inhalation action produces negative thoracic pressure during voluntary ventilation, and passive lung expansion causes alveolar and airway negative pressure, which constitutes the pressure difference between the airway opening and the alveoli to complete inhalation; after inhalation, the chest and lungs The elastic retracts, producing the opposite pressure difference to complete the exhalation. Therefore, normal breathing is due to the inhalation of the lungs and the airway mouth through the active negative pressure difference of the body to complete the inhalation, after inhalation of the thoracic and lung elastic retraction produces alveolar and airway mouth passive positive pressure difference and exhale to meet the needs of physiological ventilation.

The principle of oxygen generator: the use of molecular sieve physical adsorption and desorption technology. The molecular sieve is filled in the oxygen generator, which can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected. After purification, it becomes high-purity oxygen, which is generally not suitable for critically ill patients!

By understanding the principles of home ventilator and oxygen generator, it is easy to distinguish between ventilator and oxygen generator. Simply put, the concept of a ventilator is different from that of an oxygen generator. The ventilator is like an air compressor, providing air flow like an electric fan, which is used to help and replace people's breathing. The oxygen generator is like a sieve, screening out the oxygen in the air. There are also two kinds of machines used in the hospital to treat, generally, more serious diseases such as lung disease and heart failure.

The main users of household ventilators are: obese people, abnormal nose development, pharyngeal hypertrophy and thick, uvula obstruction channels, tonsil hypertrophy, abnormal thyroid function, giant tongue, congenital minor jaw deformity and other patients Use for symptoms like snoring and sleep apnea.
