Respirator mask

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a respirator mask.

Background

Respiration refers to the process of gas exchange between the body and the external environment. The respiratory process of a person includes three interrelated links: external respiration, including pulmonary ventilation and pulmonary ventilation; transport of gas in blood; internal respiration refers to the exchange of gases between tissue cells and blood and oxidative metabolism within tissue cells. The normal adult is at rest breathing for a time of 6.4 seconds, with a volume of gas inhaled and exhaled each time of approximately 500 ml, known as tidal volume. When a person inhales forcefully until the person can not inhale any more; then exhaling with force until the time when the exhalation is no longer possible, at which time the volume of exhaled gas is called the lung capacity. The normal adult men have lung capacities of about 3500-4000 ml and women have lung capacities of about 2500-3500 ml.

In modern clinical medicine, a respirator is used as an effective means capable of replacing autonomous ventilation by manpower, is widely used for respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation, and occupies a very important position in the field of modern medicine.
