发高烧的病人在急救时常常需要用冰袋来降温。在一时找不到冰块的情况下,可以采用本发明的冰袋。本发明采用化学制冷剂,可以迅速致冷。这种化学致冷剂分为 A 和 B 两种药剂,使用时只要将这两种药剂混合于乙烯袋中即可。A 剂为100克硫酸钠+水合物;B 剂为30克硝酸钠(也可以加入硝酸钙),经混合后4分钟,温度为-8℃。30分钟后为-2.5℃,1小时后为
Patients who have a high fever often need ice packs to reduce their temperature during first aid. In case ice can not be found for a moment, the ice pack of the present invention can be used. The invention adopts chemical refrigerant and can rapidly cool. This chemical refrigerant is divided into A and B two agents, when used as long as the two agents can be mixed in a vinyl bag. A dose of 100 grams of sodium sulfate + hydrate; B agent is 30 grams of sodium nitrate (calcium nitrate may also be added), after mixing for 4 minutes, the temperature was -8 ℃. -2.5 ° C after 30 minutes and after 1 hour
