Unlike a set of lock picks, there is a limited amount of equipment in a doctor's bag. One can use them 3 times in Fallout and Fallout 2. Gives a 20% bonus to the Doctor skill when used.
In Fallout Tactics, the Doctor skill can only be used with one of these items in a character's inventory, or a paramedics bag. Doctor's bags not only heal HP, but also cure status ailments (Conditions). Still confers a 20% skill bonus upon usage.
