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.

Claims26

Dependent claims

A multiple test applicator comprising:

a first scratching barb being cooperatively engageable with a first reservoir on a fluid tray during allergen loading, a first allergen being retainable in said first reservoir, said first scratching barb retaining some of a first allergen when removed from said first reservoir during said allergen loading;
and
a second scratching barb being cooperatively engageable with a second reservoir on said fluid tray during said allergen loading, said second scratching barb opposing said first scratching barb, said second scratching barb cooperatively engaging with said first scratching barb, a second allergen being retainable in said second reservoir, said second scratching barb retaining some of said second allergen when removed from said second reservoir during said allergen loading;
and
a first side handle secured to said first scratching barb, a second side handle secured to said second scratching barb, said first side handle opposing said second side handle, said first side handle and said second side handle configured to fit into one hand of an operator, said first side handle cooperatively engaging with said second side handle such that application of inward pressure on said first side handle and said second side handle during allergen deposition causes said first scratching barb to move in a lateral direction across a first section of skin as said second scratching barb moves in a lateral direction across a second section of skin toward said first scratching barb, said first scratching barb and said second scratching barbgrasping some of said skin, said first scratching barb generating a first scratch and depositing a portion of said first allergen into said first scratch as said second scratching barb generates a second scratch depositing a portion of said second allergen into said second scratch.
