Description

Brain fatigue countermeasure device for pilot

Technical Field

The utility model relates to mental and physical recovery equipment, in particular to a brain fatigue countermeasure device for a pilot.

Background

Flight fatigue has been a subject of great concern for many years. However, at present, no exact standard exists for research and quantitative evaluation of the occurrence mechanism of the flight fatigue at home and abroad. Fatigue is known to be a group of phenomena involving efficiency and skill damage or loss. As a complaint, it may include sleep insufficiency, interruption or deprivation due to long-term work, increased subjective tiredness, short-time loss of attention, and possibly decreased mental exercise ability. Flight fatigue can be defined as a phenomenon in which flight personnel's flight work ability is lowered, flight operation errors and the probability of occurrence of accidents are increased during the work.

Research shows that the reasons for inducing flight fatigue mainly comprise: intensity of work and duration of flight, physical quality, method of work and proficiency, degree of matching of tool equipment to people, environmental conditions, sleep, psychological burden, nutritional status, and the like. The occurrence mechanism of the flight fatigue is complex, and the flight fatigue can be considered to be the phenomenon that the flight operation capability is reduced due to continuous or repeated tasks and the physical, physiological or psychological stress aggravates the flight fatigue by combining the induction factors of the flight fatigue. While Russian specialists consider that flight fatigue is generated in the professional activities, and the flight fatigue is characterized by fatigue feeling, physiological function change and moderate reduction of the normal function state of pilots.

The causes of flight fatigue of pilots are roughly of the following three types: (1) The strength and load capacity of pilot load, the strength and duration of the workload during flight, duty and ground preparation; (2) The effect of flight stress factors, which in some cases may be the main factor in causing fatigue; (3) Individual factors such as violations of the regimen, dietary regimen, long flight interval, early stage of disease, bad habit, etc. The occurrence mechanism of flight fatigue can be understood from the following three aspects: (1) Effects of flight tasks and biorhythms on sleep arousal function. From a human perspective, flight fatigue is mainly related to the following factors: sleep deprivation or sleep insufficiency, circadian rhythm disturbances of sleep arousal, influence of flight tasks on sleep and circadian rhythms. (2) The effects of sustained flight tasks on brain function and other physiological functions. The basic characteristics of the flying labor are mental labor mainly based on multi-task comprehensive decision, long-time continuous operation can cause brain function fatigue and influence other related physiological and psychological functions, subjective fatigue feeling, especially mental fatigue feeling, is obviously increased, objective cognitive work performance is obviously reduced, and objective index change with larger difficulty is more obvious. (3) Aviation stress factors cause flight personnel to often receive continuous dynamic loads and other stress stimuli, and sports, circulation, respiration and other functional systems continuously respond to the stress factors, so that physical fatigue of the flight personnel is easily caused.

Classification and characteristics of fatigue of the body and the mind of long-endurance flying. According to the occurrence mechanism analysis of the long-endurance flight physical and mental fatigue, the flight fatigue is divided into the following main categories: global fatigue, local fatigue, physiological fatigue, and psychological fatigue. From the viewpoint of service support, it is generally classified into acute fatigue, chronic fatigue and overfatigue according to the occurrence course of flight fatigue.

Acute fatigue is caused by short but intense flight activities. The appearance of the pilot is gait swaying, action misalignment, retardation, pale or reddish skin, dyspnea, excessive perspiration and the like; objectively expressed as an increase in heart rate and respiration volume, unstable pulse and arterial pressure, and a decrease in work performance index.

Chronic fatigue may also be referred to as cumulative fatigue, due to the pilot receiving heavy workload multiple times. The subjective feeling of the pilot is tired before and during flight, weak feeling, headache, insomnia and the like, objective indexes are represented by reduced muscle strength and endurance, reduced visual sensitivity and critical flicker fusion frequency, obviously slowed down working operation and increased false action.

Overfatigue is a state of a pilot's pathological function due to a workload of great intensity over time, characterized by a significant change in physiological function and a drastic decrease in activity efficiency. The objective index of the heart rate is accelerated, the attention and the memory are reduced, pains such as neck, shoulder, waist and the like sometimes occur, the adaptability of the cardiovascular system to physical load is reduced, and the electrocardiogram is characterized by coronary insufficiency and reduces the overload endurance.

From the generation mechanism of flight fatigue and the analysis of the existing state of the flight fatigue, a comprehensive countermeasure device for the physical and mental fatigue of the pilot in long voyage needs to be designed so as to solve the following problems:

(1) After long, high load flights, blood accumulates in the lower extremities, causing hydrostatic transfer of blood from the lower body to the upper body. There are two methods currently in use: in the first method, the sitting position is taken, the two arms are lifted and put down periodically, and the duration of each posture is 8-10 s. At this point, the zero level hydrostatic pressure in the cardiovascular system moves up or down, which is associated with filling and regurgitating a certain amount of blood into the head vessels and reversing phase into the leg vessels, which helps "lavage" the organs. After a large overload flight, the pilot should lift up his hands and maintain this attitude for 8s to 10s. During this time, the heart rhythm automation completes an autoregulation cycle starting from the carotid sinus. In the second method, the prone position is taken, the knee joint is bent by 90 degrees, and the feet are lifted and put down. Taking the lying position for not less than 5min before lifting feet, taking the lying position for not less than 10min after operation, and taking the foot lifting time within 10min. With this approach, blood is redistributed from the lower limb to the head. At this point, the cerebral vessels contract, wherein blood flow is enhanced and blood filling is increased. The lying position allows maximum relaxation of the antigravity muscles subject to overload.

(2) The greater sustained flight trick acceleration effects can cause impaired activity in the neuromuscular, central nervous, cardiovascular and respiratory systems of the body, as well as in visual analyzers. Specific methods should be employed to normalize the reflex responses of the central nervous and neuromuscular systems, eliminate lower body congestion, accelerate the flow of muscle blood that is maximally loaded by static load, and minimize energy consumption to prevent fatigue. These special methods are mainly: electrophysiological methods, neuromuscular device electrical stimulation relaxation, cutaneous biological activity point axon reflex action, pulsed low frequency physiotherapy, central electrical analgesia, biological resonance energy information therapy, and the like; psychological methods, mental self-regulation, autogenous exercise, flight mental therapy on flight exercises, rational mental therapy, hypnotic cues, functional music, etc.

Therefore, there is a need to design a device that can quickly recover the mental, psychological and physical fatigue of a pilot, in conjunction with efficient completion of pilot training and flight tasks, and quick brain recovery.
