Description
Technical field
The present invention relates to human secretory object detecting method technical field, more particularly to a kind of quickly detection sweat intermediate ion are dense
The detection method of degree.
Background technique
Human body during exercise, due to internal heat production increase, so the sweat gland in each area skin of Whole Body will be secreted
Sweat, it is especially most with positions such as forehead, neck, trunk front and back, waist, the back of the hand and forearms；Perspiring is conducive to keep human body
Interior temperature distributes heat, while can also take away the internal rubbish that a small amount of human body is generated by movement.In sweat Baidupedia
The chapters and sections that keep the skin wet point out that main ingredient is water in sweat, are also mingled with some electrolyte in water, these electrolyte are main
It is sodium ion and chloride ion, general there are also a small amount of potassium and calcium.Under prolonged movement, containing for sodium is clipped in the sweat of loss
Amount is general most, and the loss of sodium ion just can not in time adjust the physiological changes such as body fluid and temperature.
In tired situation or under the movement of superpower physical load, sodium, the potassium content of sweat can change human body,
Sodium, potassium ion changes of contents can react the fatigue state of human body, under normal circumstances, during the motion, because in human body
The loss of sodium, potassium ion, sodium, potassium concentration of the human secretory in sweat can be lower and lower, " the food and strong of 3 phases in 2001
Health " " sodium potassium imbalance cause a disease the more " text point out, if the concentration of sodium, potassium ion as low as to a certain degree when, can lead to human body group
The metabolic disorder of cell and the dysfunction of each organ of whole body are knitted, threat to life is also possible to when serious, because in high-intensitive fortune
Under dynamic, sodium, the potassium concentration of sporter are changed and is measured in real time and monitors, makes adjustment in time, can be avoided movement
Person because largely sweating, lose and lead to the injury to sporter's body by body Inner electrolysis mass flow.
Application No. is the Chinese patent documents of CN201510315471.6 to disclose after a kind of movement gold in sporter's sweat
Belong to the detection method of element, detection method includes the sweat of sporter after collecting movement, sweat is filtered, in qualitative determination sweat
The type of metallic element draws atomic emissions intensity-concentration standard curve of metallic element, quantitative determines metallic element in sweat
Content；The general method for collecting sweat use is first collected to sweat using sweat patch or sweat collection bag, then again
The sweat of collection detects the ion concentration in sweat using ion analysis equipment, but in this case just pretty troublesome, and
And detection needs certain time, will lead to the lag of testing result, it can not be to the ion concentration in the sweat of human secretory
It is detected in real time, is unable to dehydration and the fatigue conditions of real time reaction sporter, therefore be badly in need of a kind of quickly detection sweat at present
The detection method of liquid intermediate ion concentration.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of detection method of quickly detection sweat intermediate ion concentration, we
Method can during the motion, and the sodium ion in sweat and potassium ion generated in real time to sporter is measured in real time, real
The dehydration of Shi Fanying sporter and fatigue conditions are reminded sporter to make movement adjustment and supplement electrolyte in time, be can be avoided
Sporter because largely sweating, lose and lead to the injury to sporter's body by body Inner electrolysis mass flow.
