SYSTEM FOR MULTI-SITE SKIN TESTING AND COMPONENTS THEREOF

摘要

This invention is a system for making multi-site skin tests primarily for use by allergists making use of a multi-head applicator (5), and a matching multi-well dip well tray (20). The applicator (5) has an elongated handle (6) with arms (8) extending transversely from opposite sides having downwardly extending legs (7) terminating in multi-pointed ends or heads (12) capable of picking up and retaining small quantities of liquid skin testing substances. The multi-pointed ends or heads (12) occupy the same plane and are arrayed in a pattern suited for simultaneously making multi-site skin tests. The applicator (5) cooperates with a multi-well dip well tray (20) with a plurality of dip wells (22) arrayed in patterns which match the pattern in which the multi-pointed ends or heads (12) on the cooperating applicator (5) are arrayed. The individual dip wells (22) have a capacity to hold quantities of skin testing substances or medicaments equaling many times the volume of a single dose or increment that is picked up by one of the multi-pointed ends or heads (12) on an applicator (5). Both the applicator (5) and dip well tray (20) have guidance formations thereon whereby the user can readily orient the multi-point pickup ends or heads (12) on the applicator (5) with the dip wells (22) so that the heads can be readily and accurately lowered into the matching dip wells (22) without damaging the points (12) of the applicator (5).
