Oxygen mask for high plateau unit

Abstract

The invention discloses an oxygen mask for a high plateau unit. The oxygen mask comprises a mask body, an elastic strap and a liquid silica gel buffer part. The mask body is a cavity for containing the nose of a person, the cavity is in an inverted T shape, and air holes are formed in the lower portion of the mask body. The liquid silica gel buffer part is arranged on the edge of the mask body. Oxygen pipe inserted connection ports are formed in the two sides of the lower portion of the mask body correspondingly, inner cavities of the oxygen pipe inserted connection ports communicate with a cavity of the mask body, and an inclination angle of 35-80 degrees is formed between each oxygen pipe inserted connection port and the mask body. The elastic strap is connected with the left side and the right side of the mask body. According to the oxygen mask, the oxygen demand of the high plateau unit under the normalized conditions of takeoff, descending and the like can be met; and the oxygen mask is exposed out of the mouth of the human body, so that a flight crew can achieve communication and wear the oxygen mask conveniently, and flight safety is improved.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to an oxygen mask for supplementary use of high-altitude units. Background technique [0002] At present, there is no normalized oxygen mask specially used for high-altitude crews. When the crew is flying on a high-altitude flight, due to the high cabin pressure, supplemental oxygen is required during critical stages such as take-off and descent, and the current on-board emergency oxygen system only supports emergency situations (such as decompression or smoke and poisonous gas) It is not suitable for long-term and normal use of the unit. Plateau flight operation is one of the characteristics of my country's civil aviation transportation that distinguishes it from European and American civil aviation. Solving the problem of supplementary oxygen for on-board personnel brought about by plateau operation has innovative significance for the development of the global civil aviation indust...
