I am looking for a Quality First Aid Kit.

Not one of those Cheap kits you see in Tesco with plaster and some alcohol in them.

I am talking about a REAL First Aid Kit the kind you hope is available when you have a severe Injury and are unable to get to a Hospital immediately.

Something like this

I know Thais don't have any training in emergency First Aid and I have been told most Thais will not even go to training if it is free.

But I need something like this in my home and my Wife will be going to Training as have I.

Any help would be appreciated.

I would suggest getting the training then putting together the kit. There's "First Aid" (band-aids and alcohol) and Trauma Kits (Stay alive long enough for the ambulance to get through traffic, what passes in LOS for an EMT to poke you with a stick and get you to an emergency room doctor that may or may not have a clue). Knowing what to do, will give you a pretty good idea of what you need.

The link you showed would do little to deal with the serious stuff that could kill you before you could get to a hospital (major arterial bleed etc). The only two items that you need in a real trauma kit that you can't easily get in Thailand are a CAT tourniquet and ChitoGauze (or Quickclot). The rest are basic things you can get at any pharmacy. If I lived in a house I would include a chest seal and decompression needle for tension pneumothorax as break-ins and shootings seem not terribly uncommon. May seem paranoid, but they don't expire and it can be used to save your neighbors as well as yourself. I know more foreigners who get in serious accidents here than I do who catch STDs, so owning a good trauma kit makes as much sense as using condoms. Reasonable precautions for a statistically significant risk.
