Description
Technical field
The utility model relates to a kind of temperature regulation system, is specifically related to a kind of refrigeration mechanism following human brain self, makes the brain heated up because of high strength mental labour recover the temperature regulation system of normal temperature.
Background technology
Generally speaking, teenager (more than 16 years old) and adult brain tissue heavily about 1.35kg, 2% of percentage of liveweight, but the blood supply required for it accounts for 15% of cardiovascular output quantity, the 20%-30% of total oxygen consumption when required oxygen amount accounts for human body rest state.Because brain cell metabolism is vigorous, therefore, certainly will produce a large amount of heat in human brain active procedure, brain also becomes the high yield hot-zone of human body, and human body is when rest, and the quantity of heat production of whole brain unit mass is higher than 6 times of the average quantity of heat production in other positions.Multinomial research shows, the mean temperature of brain is between 37.4 DEG C-38.2 DEG C, not only high than shell temperature, also be significantly higher than core temperature (rectal temperature simultaneously, 36.7 DEG C), state that when body surface and core are in normal temperature range, brain may be in " high heat ".
Meanwhile, function of brain cell is complicated and tender and lovely especially, very high to the requirement of temperature constant, even if trickle variations in temperature all can have influence on cerebral function.Under normal circumstances, except central nervous system is to (hypothalamus impels body to dispel the heat and heat production when receiving thermostimulation and cold stimulation) except the constant adjustment of temperature in brain, brain self also has a set of cooling mechanism, i.e. the counterflow exchange of incidence artery and vein blood vessel blood and Bidirectional Blood Flow.Human body scalp, face and Jugular vessel and artery are closely adjacent in position, due to the high diffusion (conduction and convection) of this place's heat, define arteriovenous blood in blood vessels adjacent during reverse flow along with considerable heat exchange, be called counterflow exchange.Such mechanism make arteria carotis blood before entering brain tissue precooling to a certain extent, be conducive to the maintenance of the normal encephalic temperature of human body; And Bidirectional Blood Flow phenomenon refers to that Head And Face exists so-called vena emissaria, when hyperpyrexia, Head And Face is perspired and is caused sweat cooling, and the blood of catching a cold directly flows to encephalic by skin surface through vena emissaria (as guided the vena ophthalmica of forehead and top, face blood), is brain cooling.That is, blood flow is just as fin, and the temperature of intracranial vessel blood flow and speed are the key factors determining that whether normal brain temperature is.
Human body in certain extreme cases, after the cognitive operation of such as high strength, the temperature adjuster system of above-mentioned brain self there will be exception, this is because the contraction diastole of blood vessel is by neuro regulation and control, and cerebral cortex neural directly domination and regulating plant nervous system, require mental skill for a long time and can cause cerebral cortex subregion overacfivity, unified coordination function is not normal, sympathetic activation and parasympathetic nerve is suppressed, cause the vasotonia spasm of brain, blood is slowly retarded by silt, arteriovenous blood back flow exchanges and Bidirectional Blood Flow mechanism is obstructed, the abnormal temperature of encephalic is caused to raise.
Encephalic temperature raises the symbol being not only brain fag, also can damage brain cell, affect metabolism, make various neurotransmitters (acetylcholine, norepinephrine, serotonin, glutamic acid etc.) abnormal distribution in the prefrontal lobe of responsible cognitive learning ability (memory, notice etc.) and hippocampus, then had influence on individual information processing capability, as judgment decline, planned difference, executive capability die down, rigidity of thinking, maintenance note and motivation difficulty etc.
We after sleep insuffience or long-time mental labour through often yawning, in fact be exactly by unfolding facial muscles, the blood flow of Head And Face blood vessel is speeded, promotes that exchange process comes to brain cooling, but depend merely on " yawning " when situation is more serious and cannot recover brain temperature regulation mechanism.
Children and youth, personnel's brain activity amount of mental worker and Long-term night shift is higher, encephalic temperature is also a little more than common people, such as be in the junior three, high three stages review the student of the key period of preparing for the examination, the study of attending class of every day is all powerful great mental labour, and often there is the phenomenon of preparing for the examination of staying up late, the most easily there is above-mentioned said vegetative nervous disorder, encephalic temperature also can increase thereupon, brain is under " high heat " state, not only cognitive ability can be had influence on, learning efficiency is caused to decline, brain tissue also can damage to some extent, cause long-term harmful effect.This kind of crowd enough can buy the product of the nutriment of some brain tonics or coffee, refrigerant oils usually; but it just supplements nutriment needed for brain work or short time Stimulation of The Brain tissue is excited; do not allow brain recover normal operating temperature and operation power, Long-Time Service also can have influence on human hormone's secretion and adolescent growth is grown.Therefore, require mental skill period in high strength, use a product that can reduce encephalic temperature in time, allow brain recover normal ability to work while restoring consciouness, it is vital that protection cerebral tissue and function are not damaged.
