　　When a bee stings (蜇) you, it doesn't just ruin your fun.The insect puts venom (毒液) into your skin, causing pain and swelling.But a chemist in Denmark believes he's come up with a simple device that will draw the venom back out of the wound, bringing victims relief.

　　Martin Wenckens got the inspiration for the Bee­Patch (蜜蜂膏药) from a home treatment he saw shown on a Danish television program.After getting stung, a person would put a slight wet sugar cube over the wound.The idea is that through osmosis - the movement of a fluid from an area with a lower concentration of molecules (分子) to an area with a higher concentration - fluid moves from the small hole up into the sugar cube, carrying the venom along with it.

　　Because exposed sugar may attract more insects, Wenckens thought he could improve on the treatment.He put sugar inside a patch that can be worn like a bandage.The side touching the skin has a thin layer through which fluid can move."After you get stung, place the patch on the injured skin and leave it for one hour，" Wenckens says."This will lower both pain and swelling." He cautions that people with insect allergies should continue to use medications recommended by their doctors.

　　Wenckens designed the Bee­Patch especially for children, but he reports that lifeguards and soccer players are also using it."In many schools in Denmark, the Bee­Patch is already a part of first aid kits，" he says."To have invented a small patch that can be used by so many people of course makes me very proud."
