The MEDI-DART Projectile, Extension, or Crossbow syringe, invented by a group of central Alberta ranchers, makes medicating pasture cattle easy and less stressful for livestock. The MEDI-DART systems are easy to use and inject larger doses of medication than other medicating systems.
MEDI-DART is used to give a single intramuscular or subcutaneous injection to livestock without restraining the animal. MEDI-DART also self-ejects once the injection is completed. At the end of the injection, a push rod is pushed ahead, which removes the needle from the animal for easy retrieval of the syringe.
