ABSTRACT:
A system for making multi-site skin tests primarily for use by allergists making use of a multi-head applicator and a matching multi-well dipwell tray. The applicator has an elongated handle with arms extending transversely from opposite sides having downwardly extending legs terminating in multi-pointed ends or heads capable of picking up and retaining small quantities of liquid skin-testing substances. The multi-point ends or heads occupy the same plane and are arrayed in a pattern suited for simultaneously making multi-site skin tests. The applicator cooperates with a multi-well dipwell tray with a plurality of dipwells arrayed in patterns which match the pattern in which the multi-pointed ends or heads on the cooperating applicator are arrayed. The volume of testing substance or medicament in a dipwell will equal many times the volume of a single dose or increment that is picked up by one of the multi-pointed ends or heads on an applicator. Both the applicator and dipwell tray have guidance formations thereon whereby the user can readily orient the multi-point pick-up ends or heads on the applicator with the dipwells so that the heads can be readily and accurately lowered into the matching dipwells without damaging the points of the applicator. The handle of the applicator also has formations on it which prevent the applicator from being used wrong-end-to.
