The body recalibrator is the perfect tool for on the job injuries no matter the severity. The recalibrator heals any injuries the user has sustained and heals them fully, even lost limbs are regrown. This is possible via the philosophers blood within the recalibrator; special proteins read the user's Dna and rebuild the body based on it, once the blood is in the system it will last for 5 hours before the proteins die. Birth defects are not healed due to them being embedded in the dna, But limb loss, lobotomies, and cancer cells can all be fixed with just a stab from the body recalibrator! 

Warning: NOT INTERSPECIES These are built for only a select group of species with humans and lacopus being the default. To change the species insert a drop of blood from the desired species and insert into the tip of the recalibrator. Then wait, if the philosophers blood is a mix of colors then the blood will now work. If it is a solid color then it will not work on that species.
