An Oxygen Mask Mould is an emergency rescue device that provides oxygen to passengers. If the cabin suddenly loses airtightness or encounters other hypoxic conditions, passengers can get oxygen masks to supplement oxygen at any time.

The oxygen mask provides a way to transfer the oxygen needed for breathing from the storage tank to the human lungs. There are mainly medical oxygen masks, aviation oxygen masks and oxygen masks used by airline passengers, which play an important role in curing diseases and protecting the safety of passengers and pilots. Mainly made of plastic, silicone, or rubber.

After the airplane reaches a certain altitude, pressurize the cabin. If the aircraft cabin loses pressure, it will cause hypoxia, and passengers will feel dizzy, lose consciousness, and even endanger their lives under hypoxia. In the case of cabin depressurization at different altitudes, the duration of hypoxia that people can withstand is different. The higher the flight altitude, the less time to withstand. In civil aviation airliners, each person’s seat is equipped with a personal oxygen mask for emergency use, so there is no need to fight to avoid pulling the oxygen mask and delaying use.

The oxygen mask is connected to the automatic coupling through a slender rubber oxygen supply tube and a bayonet joint. Oxygen continuously flows into the air storage bag of the mask. The gas storage bag first stores gas, and when it expands, it can hold a certain amount of oxygen. When the passenger takes a deep breath to empty the air storage bag, the air intake valve on the Medical Mould can let in oxygen.
