Description
Technical field
The present invention relates to a kind of first aid dressing for traumatic surface, be specifically related to a kind of first aid dressing for cold district traumatic surface and preparation method thereof.
Background technology
People are out of doors during operation, injured always unavoidable, and show as wound more.Wound generally refers to because of tumbling down, external force collision, weapons damage, and insect and animal biting, scalds, the paathogenic factor such as burning, cold injury and the skin and flesh muscles and bones and the internal organs that cause are injured.The traumatic condition of wound shows as that multiple location multimachine reason is complicated and changeable, and traumatic surface, as do not processed in time, traumatic infection very easily occurs, or Massive Bleeding, can cause the serious pathological changes such as stupor, tic, YANG-depletion collapse.
Especially in the wild, and lower Huo Han in the winter district of some temperature be also often attended by the generation of cold injury.Because China is located in northern warm area, three northern areas of China are colder winter, and some areas minimum temperature reaches-30～-40 ℃, in the wild or at durante bello, because worsening condition is also very easy to occur cold injury.The reason of cold injury mostly is ambient temperature and reduces, keep warm measure is unfavorable, next is that wind speed accelerates to increase limbs thermal loss, cold adds strong wind, the effect of cold injury will obviously be accelerated, and is originally unlikely to cause the low temperature of cold injury, because wind speed is large, just can cause cold injury, in addition tired, hungry, to have a delicate constitution etc. be all the important inducement of cold injury.Cold injury, according to there being inorganization freezing process, is divided into the property freezed cold injury and the non-property freezed cold injury.Be exposed to for a long time or repeatedly under cold and moist condition, due to local organization poor circulation, histotrophic nutrition obstacle and what occur is the non-cold injury of freezing without the cold injury in the melting process of freezing.Sometimes temperature is 10～0 ℃ of left and right, and heat-retaining condition is poor, when particularly humidity is larger, the non-cold injury of freezing also can occur, and comprises chilblain, immersion foot and trench foot, and severe frostbite is due to thrombosis, disturbance of blood circulation, finally causing endures cold organize destroyed.
If nearer apart from medical institutions when the injured residing region of the wounded, can wait for the relief of hospital.But if injured residing region is far away apart from medical institutions, just can only rely on Field Force's self and mutual medical aid, if necessary medical rescue cannot must be implemented in time, the harm meeting that health is caused is larger.
