Rewarming device for wounded person

Abstract

The invention provides a rewarming device for a wounded person. The rewarming device comprises a carbon heating module, an electric heating module and a rewarming bag body. The carbon heating module and the electric heating module are arranged, so that the device can be suitable for field use and can also be suitable for rear use; two electric heating tube sets are arranged in the electric heating module, one electric heating tube set can be used for body surface heating, the other electric heating tube set can be used for breathing rewarming, and therefore body surface rewarming and breathing rewarming can be conducted at the same time; combustion waste gas and hot air are separated in a bent mode through the arranged carbon heating module, the hot air used for rewarming is prevented from making direct contact with combusted compressed carbon blocks, and safety is improved; the bag body is provided with a bag body air inlet connector and a bag body air return connector, so that rewarming hot air forms closed-loop circulation, the temperature in the bag body is convenient to control, and rewarming complications caused by sudden rising of the temperature in the bag body are avoided.

Description

technical field [0001] The invention relates to the technical field of rewarming, in particular to a rewarming device for the wounded. Background technique [0002] At present, the existing rewarming devices are suitable for single scenarios, such as rewarming devices using fuel oil heating and rewarming devices using water bath heating, which have complex and bulky structures and poor portability; and rewarming devices using electric heating have large power consumption In the low temperature environment, the efficiency of the battery itself will be significantly reduced, and it is difficult to perform in the harsh environment of the emergency scene. These rewarming devices are difficult to adapt to field use. Moreover, the existing rewarming device has a single rewarming method, most of which can only heat the wounded body surface, and if the body surface rewarming temperature is not well controlled, it will lead to overheating (overheating will easily cause a large area o...

AI Technical Summary

Problems solved by technology

[0002]Currently, the existing rewarming devices are suitable for a single scenario, such as the rewarming device using fuel oil heating and the rewarming device using water bath heating are complex and bulky in structure and poor in portability ; Another example is that the electric heating rewarming device has the disadvantage of large power consumption. In a low temperature environment, the performance of the battery itself will be significantly reduced and it is difficult to perform in the harsh environment of the emergency scene. These rewarming devices are difficult to adapt to field use.

Moreover, the existing rewarming device has a single rewarming method, most of which can only heat the wounded body surface, and if the body surface rewarming temperature is not well controlled, it will lead to overheating (overheating will easily cause a large area of ​​body surface temperature to rise suddenly and cause a large amount of low-temperature blood to surge. into the heart, causing the heart temperature to drop rapidly by 1-2°C, leading to cardiac arrest, and at the same time, the expansion of peripheral blood vessels, resulting in insufficient effective blood circulation and rewarming shock), resulting in rewarming complications
