One kind can microwave and the incubator reused,The incubator includes a fever backpack body and a carrier； Wherein fever backpack body sets the inside of what carrier,It is the supersaturated aqueous solution of inside filling sodium acetate of one pouch of what etc.,It is nonmetallic reactant that one is equipped among the supersaturated aqueous solution of sodium acetate etc.,The supersaturated aqueous solution that the inside of the reactant is equipped with to trigger sodium acetate etc. crystallizes and the crystal seed of the supersaturated aqueous solution substrate of fever； Thereby,Can via microwave to the incubator Repeat-heating,Make the heating method of incubator can be more diversified,It can also the safety that uses of Yi Ti Noboru.一種可微波而重複使用之保暖器，該保暖器包括一發熱包體和一載體；其中發熱包體設於載體的內部，其係於一囊袋的內部填充醋酸鈉等之過飽和水溶液，在醋酸鈉等之過飽和水溶液之中設有一為非金屬之反應體，該反應體的內部設有用以觸發醋酸鈉等之過飽和水溶液結晶而發熱之過飽和水溶液基材之晶種；藉此，可經由微波對該保暖器重複加熱，使保暖器的加熱方式可更多樣化，也可以提昇使用的安全性。
