I devised my own - I think this is the best thing to do - for your circumstances. For me, I’m not a prepper at all but I did live in a relatively isolated village for a while and mine was built up over about 10 years with the help from medical friends. I’ve just read it to DH and he laughed and said that’s not a normal first aid kit and I suppose it isn’t I think I grew up quite self reliant and I’m not a doctor but I have a fairly good first aid grasp. I’m also autistic so when I did a first aid kit I did brain storm and then add to it.
I have the following in the house:
Big kit:
Tourniquet x2
Tooth first aid kit (emergency)
Pliers
Medical Scissors
Scalpel
surgical thread
Tweezers
Medical gloves x 200
Huge medical pads to stop bleeding different sizes
Syringes
Breathing tube
Foil sheets
compresses and flannels
Bowls
Urine sample bottles
urine strips
Other more normal first aid stuff boxes these are separated and labelled in different boxes eg pain relief :
Thermometers x2 (spare batteries) and nose cones for thermometers
Oxygen monitor
Blood pressure reader
Tweezers, Scissors
Bandages
Sling
Gauze
Pads
Plasters
cotton wool (proper stuff)
wipes
burn gel
medical Tape
Steri strips
Break up ice pads
Heating self adhesives pads (hot water bottle)
Ice cap (put ice inside)
Cold sore patches
sanitary towels
tampons (good to stop bleeding in cuts too)
Sterile cloths
Eye Bath and eye solution
Antibacterial gel & alcohol gel
Alcohol spray
Iodine
Salvon Spray
vaseline
metanium
sudocream
e45
piles cream
immodium
Althete foot cream
thrush cream
uti antibiotics
broad range antibiotics
safety pins
needles
thread
blister pads
antihistamines
epipens
steroids
Pain relief (paracetamol, aspirin, ibuprofen, morphine, naproxen, cocodemol, calpol )
vocal zones
vicks
matches
tablets and filter to make water safe
We also have a car first aid kit / which is a smaller version of the one above. And we have animal first aid kits (antihistamines, general bandages etc and suture kit, alcohol spray and a wound powder etc and these are in the car and in the house).
I do realise we are very first aid kit rich - really large cupboard in downstairs bathroom. I check it twice a year.
I don’t really think we have had to use it much. We have the occasional cut or bruise and occasional antihistamines, I haven’t had to use my EpiPens for 3 years (I know my allergy and although I carry them I haven’t had to use it). DH cut his finger badly a year or so ago and my son did use some of the bleeding things to stop it and cleaned the wound up and steri strips etc but I took him to minor injuries when I got home- as the cut was very, very deep and large. But I do think the first aid my 12 year old did was pretty exceptionally good and saved DH some problems - minor injuries were impressed and double checked it. (Lots of blood in the kitchen to clean up though!)
We are all first aid trained including my son, I think it is a good skill to have.
You don’t need the all above for me it comes from habit of living a bit isolated and being fairly self reliant for over a decade. I was also the person that other people could rely on to have x or y.
Batteries - I have every battery you can want (or fuse) or bulbs. This goes back as I say 20 years when I lived isolated and relied on myself.
