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.

Claims

1. An allergy testing apparatus for testing a patient for a plurality of substances, comprising:

a rotatable, drum-like member;

a plurality of spaced apart pricking or piercing means coupled to said drum member and extending substantially radially of said drum member and being spaced apart relative to each other over a circumferential portion of said drum member;

resilient means over said pricking or piercing means for at least partially covering said piercing or pricking means;

substance containing means mounted over said resilient means and including a plurality of substance sources spaced from each other and in registration with respective pricking or piercing means; and

operating means coupled to said rotatable drum-like member for applying said rotatable drum-like member against the skin of a patient and for pressing said rotatable drum-like member in the direction of said skin of said patient to compress said resilient layer to thereby cause said pricking or piercing means to extend through said resilient layer and to pass through said respective substance sources so as to contact a respective substance and to then pierce or prick the skin of a patient, thereby applying the substance in registration with the respective pricking or piercing means to the skin of a patient, and for rolling said drum-like member along the skin of a patient to sequentially apply substances to the skin of the patient at spaced apart locations on the skin of the patient by respective pricking or piercing means, as said drum-like member is rolled along the skin of the patient.

2. The allergy testing apparatus of claim 1, wherein said operating means comprises a handle coupled to said rotatable drum-like member, said handle being operable manually by an operator.

3. The allergy testing apparatus of claim 1, wherein said spaced apart pricking or piercing means comprises a plurality of spaced apart elongated needles.

4. The allergy testing apparatus of claim 1, wherein said spaced apart pricking or piercing means are mounted in a sleeve-like member which is mounted over said rotatable drum-like member, said piercing or pricking means extending radially from said sleeve-like member.

5. The allergy testing apparatus of claim 4, wherein said resilient means comprises a resilient sleeve-like member mounted over said sleeve-like member carrying said pricking or piercing means and covering said pricking or piercing means.

6. The allergy testing apparatus of claim 5, further comprising locating means for locating said sleeve-like means which carries said pricking or piercing means relative to said drum-like member.

7. The allergy testing apparatus of claim 5, wherein said substance containing means comprises a sleeve-like member which is mounted over said resilient means and containing said substance sources in registration with respective piercing or pricking means.

8. The allergy testing apparatus of claim 7, further comprising locating means for locating said substance containing means in a predetermined position relative to said drum-like member for orienting said respective substance sources at a predetermined position relative to said drum-like member.

9. The allergy testing apparatus of claim 8, wherein said substance containing means comprises a sleeve-like member having a plurality of receptacles therein for containing said plurality of substance sources in said respective receptacles;

and means covering said respective receptacles for maintaining said substance sources in said respective receptacles.
