Multifunctional pilot helmet

Abstract

The invention discloses a multifunctional pilot helmet. The helmet comprises a superfine elastic bristle structure electroencephalogram collecting device and a blood flow condition detecting device. The superfine elastic bristle structure electroencephalogram collecting device comprises a brain electrode beam array, the brain electrode beam array is composed of a plurality of brain electrode beams, the brain electrode beams are superfine elastic conductive bristle bundles, and the superfine elastic conductive bristle bundles are composed of a plurality of superfine elastic conductive bristle ; and the blood flow condition detection device identifies blood oxygen signal characteristics by collecting subcutaneous blood oxygen concentration change signals of the pilot and indicates whether the blood flow condition of the head of the pilot is normal or not. The multifunctional pilot helmet can make elastic contact with the scalp to conduct good electrical connection so as to accurately collect electroencephalogram signals, can also collect blood oxygen concentration change signals of the cerebral cortex of the pilot, identifies blood oxygen signal characteristics and indicates whether the blood flow condition of the head of the pilot is normal or not.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a multifunctional pilot helmet. Background technique [0002] When the pilot is flying with high maneuverability, the continuous positive acceleration will transfer the blood to the lower half of the body, reduce the arterial blood pressure at the level of the brain, and reduce the blood flow in the brain, which will cause brain tissue ischemia and hypoxia, which will easily cause loss of consciousness and flight visual impairment, resulting in Misjudgment poses a great threat to flight safety. Therefore, it is necessary to monitor the pilot's physiological state in real time, especially parameters such as EEG, eye blood flow and blood pressure, facial skin color changes, and breathing. Forewarning. [0003] Spatial disorientation, also known as flight illusion, refers to the wrong perception of the aircraft and its own position, attitude, and trajectory during flight. If this kind ...

AI Technical Summary

Problems solved by technology

Because the pilot cannot realize the occurrence of the flight illusion in time and lacks effective countermeasures, spatial orientation disorder may cause serious flight accidents, resulting in huge economic losses and personal injuries
