Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sea rescue, concretely relates to a respiratory tract temperature raising instrument for a person with low body temperature falling into the sea. BACKGROUND

[0002] Under normal environmental conditions, respiratory heat dissipation accounts for 10% to 30% of the whole body heat dissipation, and the lower the air temperature, the higher the proportion. Respiratory rewarming is to input heat to the brain stem, the sympathetic nerve of the neck and the pacing area of the chest through inhaling warm (43-45 DEG C) and saturated water vapor air, so as to reverse the respiratory center inhibition caused by hypothermia and improve the perception level. A small amount of heat input can significantly improve the rewarming effect. At the same time, the related areas of the neck, chest and heart contain important organs for maintaining life functions, and respiratory rewarming is also an effective means of providing basic life support. In addition, respiratory rewarming is a non-invasive treatment method of body core rewarming technology, which is the preferred method for treating patients with hypothermia, especially severe hypothermia patients. RES-Q-AIR Model 1000 body core rewarming instrument is widely used in the army of Canada, the United States, Germany, Switzerland and the United Kingdom.

[0003] At present, the on-site rewarming treatment of the personnel falling into the sea in China mostly adopts body rewarming technology, mainly including blanket rewarming, ventilation rewarming and water bath rewarming, and the treatment efficiency is relatively low, which cannot effectively treat patients with moderate and severe hypothermia.

The rewarming sleeping pad and the water storage bag can be folded and stored when not filled with water, so that the whole device is compact in size and convenient to carry. The rewarming treatment can be carried out as soon as possible on the scene, and the rewarming effect of the wounded person is maximized. However, it is also difficult to effectively treat patients with moderate and severe hypothermia. UTILITY MODEL CONTENT
