Abstract:
An allergy testing apparatus for testing a patient for a plurality of allergies at the same time comprises an actuating member resiliently suspended from a frame member and which is movable relative to the frame member. A plurality of spaced apart substance sources are mounted in the frame member below the actuating member. A plurality of spaced apart needles or the like are mounted on the actuating member and extend in the same direction so as to pierce the respective substance sources during movement of the actuating member toward the skin of a patient to apply the substances to the skin of a patient. According to another feature of the invention, the device is shaped like a rotatable, drum-like device, having a plurality of layers. The needles or the like are covered over by a resilient layer, and substance containing means are mounted over the resilient layer and in registration with the respective needles. When the device is pressed against the skin of a patient, the resilient layer compresses, permitting the needles to pierce the substance containers to apply the substances to the skin of a patient.
