Intramuscular injection training model

This is a model for practicing intramuscular injection into the upper arm. This model is not for beginners or students. It is intended to be used by health care professionals who have already learned intramuscular injections to check and review the technique.

This model consists of parts for the arm and mold parts for the muscles.
Print the top and bottom of the mold parts, combine and secure them with tape, and pour in the gel. Choose a gel that is similar to human skin. I recommend Smooth-on's Ecoflex 00-30.
Print out the arm parts and fit the hardened gel. At that time, place a water-absorbent sheet cut to an appropriate size on the backside of the gel.
