This is the Liquid Enhanced Instrument or as we call it: the LEI unit. This advanced medical instrument is meant to treat slight or medium sized cuts or injuries by releasing a liquid bandage solution. The main unit consists of a disposable liquid bandage capsule that is inserted into the pen like instrument. The pen has a battery compartment that is used to release the liquid and warm it up a little bit to eliminate germs and prevent hardening of the liquid capsule. The capsules can be purchased in minimum packs of five but packs of ten to thirty can be purchased if needed. The liquid does not expire. The screw on cap ensures that no liquid is dispersed when not in use. The LEI medical instrument would definitely be an ideal choice for the three-year trip to Mars!
