Particularly, it is not possible to administer drug by wrong route due to the fact that the injector orifice (22) is not compatible with the cannula diameter. Besides, due to the fact that the orifice (22) has an amorphous structure, integrity of oral mucous membrane can be maintained.
  • the notches (23, 24) included on the body (2) and the piston (3) enables to administer drug at a safe speed by facilitating gripping and preventing slipping and avoids airway aspiration.
