Abstract: A medical information key chain for use in emergency situations with a simple and concise means of quickly identifying the person and emergency medical information, includes a casing, key ring, and an information tag. The key ring would attach the tag to the user's keys. The tag could be manufactured from a variety of materials including but not limited to plastic, stainless steel, brass, pewter, silver, gold and platinum. The medical information key chain would be custom engraved by the wearer with vital identification and emergency medical information. This information would include the wearer's name, the doctor's name, address and telephone number, as well as a list of medications. The medical information key chain may also be engraved with other pertinent medical information such as the wearer's blood type, allergies to medication and recent surgical procedures.
