ABSTRACT:
An improved intraosseous injection system including an injection needle constructed of high strength metal to resist bending and buckling mounted within a protective and supportive sleeve. The sleeve includes a retractable cannula for additional protection and support of the needle and a measuring gauge for precise sighting alignment to properly locate the site for an effective anesthetic injection. The movement of the retractable cannula is limited by a stop which operates to position the needle at the correct depth of penetration for delivery of anesthetic to the most effective location.
