In long-term survival, you might run out of medical supplies and have to improvise with found objects. Here are some that might prove useful:
Bandages: Don’t throw away old sheets! Cut them into strips to make bandages. Also, maxi pads and other feminine hygiene products are useful additions to your stockpile of dressings.
Tourniquet: A bandanna and a stick can be repurposed to help stop bleeding. Wrap the bandanna 2 inches or more above the wound, then tie a knot to hold it in place. Place a stick on top of the knot, then tie it to the bandanna with another knot. Twist the stick to apply more pressure on the bleeding limb.
The pillow splint: To immobilize and protect an orthopedic injury, consider wrapping the limb with a pillow and some duct tape. Add two boards for further stability, especially in fractures.
The improvised stretcher: Commonly found items left behind in abandoned homes can be repurposed for use as stretchers, among other things. Consider ironing boards, chairs or broomsticks with jackets or shirts, blankets, rope and more.
Wound closure: Duct tape can be used to approximate wound edges of lacerations. Make two cuts on each side and fold over, adhesive-toadhesive, to make a non-adhesive area and then place tightly to close the skin. Make sure the non-adhesive area is over the cut itself.
Pain relief: The green underbark of willow trees contains salicin, from which the first aspirins were made. Cut into strips to make a tea.
Prevent infections in various wounds: When there’s no antibiotic ointment, utilize the antibacterial action of raw, unprocessed honey by spreading some over burns and other wounds. Then, cover the wound with a dressing.
Portable toilet: A 5-gallon bucket and a plastic garbage bag can be used to make a perfectly serviceable toilet. For more comfort, add a product called “the Luggable Loo” as a seat. Cover human waste poured into a hole with sand or kitty litter.
