Hi ! Medic Troll here...
anyway, we've all collected stuff. medical stuff is of great importance if you're the designated "doc".
I've stressed "sick call" type supplies. minor wound care, earaches, UTIs, blister care, burn care, rashes, creeping crud like athletes foot, (all can be debilitating if left out of control) etc.
i've stocked cotton balls, silver colloidal solutions, tea-tree oil, lavender oil, suture sets and removers, and lots and lots of "disposables" that will be consumed quickly with dressing changes, etc.
Hygiene is of the utmost importance after SHTF. More have died in wars from disease than wounds, ever. water purification and food care/prep is also the medics job. prevention is better than cure. I stock cheap soap bars by the pound. shampoos by the gallon. i use only antibacterial soap for wound wash and pre-procedure wash. regular soap otherwise. alcohol, whitchhazel, peroxide by the gallon. betadine from a vet supply. calmine lotion, every type of OTC you can get ahold of. dont forget toilet paper by the case. also grooming products like nail clippers, combs, etc.
I hit the dollar stores and spend $50.00 to $100.00 every month. Think basic first aid supplies, bathroom supplies, invalid care supplies, etc.
I have a trauma bag as well that goes with me everywhere I go. except for drugs and a defibrillator I can operate to my skill level and i have cooperation from by base hospital to do so.
SHTF is another sitch alltogether. Simply put, in the absence of an ICU or life saving trauma surgery, if you're seriously hurt in SHTF, you're dead. no amount of prehospital care, drugs, edison medicine, IVs, needle thoracotomies, ETTs, etc will change anything in someone needing care past the first hour. be realistic, all of our training is suited for buying time for the injured, not fixing a damn thing.
I expect to use my trauma bag as well as my other medical supplies, post SHTF, but my expectations of evacuating a seriously injured party to a hospital are low. there will be no additional help, in my case, and people will die in heretofore preventable cases. it's simply what will happen when we revert back to the 1800s.
save who you can. prep for that. good luck with NREMT.
