Antigen injection assembly

摘要

A tray having a number of spaced, individually spaced cavities extending downwardly therein in which tubular containers are removably disposed that contain biological active liquids. The containers have open tops in which resilient stoppers are sealingly disposed. Each stopper has a longitudinal bore therein that terminates on the upper end in a projecting bubble. Each bubble may be severed from the stopper with which it is associated by cutting transversely through the base of the bubble with a sharp sterile instrument such as a razor blade or the like. Immediately upon the bubble being severed, an elongate sterile applicator is removably and sealingly disposed in the bore associated with that bubble The applicator includes a handle from which a tapered shank projects to terminate in a flat first end from which a number of spaced needle like projections extend, with the projections being of a length that is the depth that is desired to have same penetrate into the skin. When the applicator is slidably removed from the bore in a stopper, a predetermined quantity of the biological active liquid will adhere. When the projections are forced into the skin of a patient the adhering liquid is transferred to the patient. The first end of the shank acts as a stop by contact with the skin of the patient. The applicator assures not only that a predetermined amount of liquid will be injected into a patient, but limits the depth to which such injection will be made. The applicator after use is discarded, and a new sterile applicator is inserted in the bore of a stopper to seal the liquid in the container associated with that stopper from contact with the ambient atmosphere.
