Emergency kit types?

Should a emergency kit have a specific type? For example, should it be focused in general treatment or in other more specific situations? Because in a general treatment you may not have tools for a more specific treatment.

 

I think you would need a specific type of kit based on your situation. For example if you have someone with you that has certain ailments you might want to have things in your kit that cater to there needs. Or if your going somewhere and you assess the dangers you could face you can modify your kit to be prepared for those types of situations.
