The kit looks good. The only application that I can think of for this type of kit in civilian life would be to keep it in the car. (Unless you are in law enforcement in which case you should probably carry it at all times to treat gunshot and stabbing wounds).

The types of injuries this kit would treat, all involve some sort of severe bleeding, something not commonly encountered in everyday life, except perhaps for car accidents.

I have a Bloodstopper and some maxipads in my car kit for severe bleeding, plus some 4x4s and Durapore tape for the less severe one. Tourniquete can easily be improvised. As far as nasopharyngeal airway, this could be an overkill unless one knows how to use it well.
