Patent ID: 11696722

Abstract:
A multiple test applicator has a first and second scratching barb in cooperative engagement with each other and a first and second reservoir in a fluid tray each filled with a first and second allergen. During allergen loading, the first allergen is loaded onto the first scratching barb as the second allergen is loaded onto the second scratching barb. Then, during allergen deposition the applicator is removed from the fluid tray and the first scratching barb moves laterally across the patient's skin as the second scratching barb moves laterally across the patient's skin toward the first scratching barb. The first scratching barb then scratches the epidermis at a first test site as a trace amount of the first allergen is deposited into a first site as the second scratching barb scratches a second site as a trace amount of the second allergen seeps into the second site.
