Abstract
An injection device includes a housing, a plunger, and a heating unit. The plunger is slidably arranged within the housing thereby performing a plunging movement therein. The heating unit is disposed within the housing for generating a heat energy inside the housing such that a filling material inside the housing can be soften and be transformed into a movable filling material with viscosity by absorbing the heat energy from the heating unit.
