Abstract
Abstract An organizer, particulary useful in a dental clinic practicing operative dentistry, comprises a portable tray having compartments defined thereon to retain at least one syringe, a needle encased within a protective sheath, and a hermetically sealed cartridge containing a liquid anesthetic or other liquid drug or medication adapted to be administered to a patient. In the preferred embodiment of this invention, one of the needles encased within an opened protective sheath is mounted in the same compartment as the syringe and aligned therewith whereby the syringe can be readily attached to the needle. A reciprocal finger button is mounted on the tray and has a detent engageable with the protective sheath to facilitate removal of the syringe and the attached needle from the sheath.
