Abstract

The present invention is directed to an intradermal injection system adapted for multiple mass use, particularly for mass diagnostic testing such as the Heaf Multiple Puncture Tuberculic Test. The structure includes an elongated finger grip skin puncture applicator with a set of puncture points mounted in the base face of the applicator. Associated with the applicator is a solution holder having therein an antigen well of pre-determined capacity. An escape channel leading to an overflow well removes any excess antigen from the well. Upstanding from the center of the antigen well is a centering and stop element which cooperates with a correspondingly shaped depression inside the base of the applicator so that the applicator may be centered in the antigen well with all of the applicator puncture points wetted by the antigen solution therein to a pre-determined level.

Claims

1. An intracutaneous applicator system comprising an intradermal applicator member removably received in a solution supply holder, said member and holder cooperating to apply solution to said applicator for intradermal injections, said applicator having a base injection surface, a plurality of puncture or scarifying means located on said surface and projecting therefrom, a centrally located depression in said surfacE, a first well in said holder, an upstanding projection in said first well of a predetermined shape and extending into said depression to center the applicator member in relation to said first well and limiting the depth of penetration of said base surface and puncture means into said first well, an overflow well located in said holder, an escape channel means in the top of said holder and communicating with both said wells whereby excess solution placed in said first well will pass to said overflow well to limit the amount of solution in said first well to a predetermined level, said level being related to the limited depth of penetration of said applicator by said upstanding projection so that only said puncture means are coated with said solution and not said base surface thus facilitating that an accurately determined amount of solution will be on said applicator when used on a patient.

2. A system as in claim 1 wherein said upstanding projection has a peripheral ridge thereon, the shape of said projection and depression being such that said ridge is sized to contact the area of said base surface to limit the depth of penetration of said applicator into said first well, said ridge also acting as a visual indicator for determining when said first well has a predetermined amount of solution therein.

3. A system as in claim 1 wherein the top of said holder is generally depressed, said first well and upstanding projection being located in the center of said depressed top and said overflow well being located adjacent said first well.

4. A system as in claim 1 wherein said upstanding projection and said depression are both frustro-conical in shape and said puncture or scarifying means are integral with an insert piece located on said base surface, said insert piece having a central aperture overlying the opening of said depression, said puncture or scarifying means being equally spaced from said depression.
