The internationally-used Thermal blanket is actually made of aluminum foil.
Thermal blankets need to be insulated as the name implies. When it is cold, it can be wrapped around the body or the parts that are susceptible to freezing. It can reflect the heat emitted by the human body and achieve the effect of heat preservation. A drop in body temperature can exacerbate the injury of the injured person, and the wrapped thermal blanket is a protection for the injured patient. In addition, when the injured patient is wrapped in a thermal blanket, indicating that the person has been injured and has passed the primary first aid, the medical staff will give priority to further examination and treatment, and the chance of being injured will increase. When the field is killed, the thermal blanket is wrapped around the body, using its reflective effect to help rescuers find their targets. The thermal blanket is tough, lightweight, soft and malleable and can be used as a stretcher. Of course, this stretcher is only a temporary measure for short-distance use. Pay attention to the synchronous operation when using, otherwise it will be easily torn and the patient will be injured.
