tourniquet is a device used to apply pressure to a limb, effectively stopping or reducing blood flow. They are primarily used in emergency situations to control severe bleeding from a limb, and also in surgical settings to create a bloodless operative field.
Alcohol swabs are small, individually wrapped pads saturated with 70% isopropyl alcohol, used for cleaning and disinfecting the skin before injections, blood draws, or minor surgical procedures. They are also useful for cleaning minor cuts and scrapes, and can be used to disinfect surfaces or medical tools.
