原理:根据高锰酸钾与过氧化氢(通常称“双氧水”)起化学反应产生氧气的原理,取竹筒和瓶子装置而成。其化学反应式是: 2KMnO_4+3H_2O_2=2MnO_2+2KOH+2H_2O+3O_2↑制法:取三节的竹筒一根,中节装洗气瓶。需用氧气时,打开开关,过氧化氢溶液滴入高锰酸钾瓶内,当洗气瓶出现气泡时,即可输氧(装置见附图)。用途:适于没有输氧设备的农村卫生单位急救输氧用。
Principle: Based on the principle of the chemical reaction of potassium permanganate and hydrogen peroxide (usually called “hydrogen peroxide”) to produce oxygen, it is made from bamboo tube and bottle device. Its chemical reaction formula is: 2KMnO_4+3H_2O_2=2MnO_2+2KOH+2H_2O+3O_2 yttrium method: Take one of the three sections of the bamboo tube, the middle section of the loaded gas cylinder. When oxygen is used, open the switch, and the hydrogen peroxide solution is dropped into the bottle of potassium permanganate. When bubbles appear in the gas bottle, oxygen can be delivered (see the figure in the figure). Uses: Suitable for first aid oxygen delivery in rural health units without oxygen delivery equipment.
