Allergy testing apparatus and method
First Claim
1. An allergy testing apparatus for testing a patient for a plurality of allergies at substantially the same time, comprising:
- a frame member;
an actuating member resiliently suspended from said frame member by suspending means;
actuating means on said actuating member for moving said suspended actuating member relative to said frame member;
a plurality of spaced apart substance sources mounted in said frame member below said actuating member for carrying respective substances which are to be applied to the skin of a patient for testing; and
a plurality of spaced apart pricking or piercing means on said actuating member and extending in substantially the same direction, each pricking or piercing means being associated with a respective substance source, said pricking or piercing means being movable from an inactive position out of contact with the skin of a patient to an active position for pricking or piercing the skin of a patient and applying an associated substance from said respective substance source to the skin of the patient when moved from said inactive position to said active position;
said actuating member being movable relative to said frame member against the resiliency of said resilient suspending means for moving said plurality of pricking or piercing means from said inactive position to said active position to contact said substances contained in said plurality of spaced apart substance sources, respectively, and to apply the respective substances to the pricked or pierced skin of the patient at substantially the same time with said substances being spaced apart on the skin of said patient.

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. Adjustable length substance carrying means are also disclosed.
