Mountaineering Injuries and First Aid

Okay I'm Adam and basically I am basically designing a first aid kit for Mountaineers. It will be carried on the person in some way or another.

I was hoping someone could shine some light on the main injuries as in the most common ones as I don't really know much about the sport so could anyone please shed some light on this ? (volume of injuries and where on the body?)

I presume Mountaineers will have First Aid kits handy in case of an accident minor or major ?

I would like to know what Mountaineers would take with them whilst climbing the mountain ?

Thanks for any help, it is much appreciated guys and girls. Thanks in advance.
