Abstract
Abstract A device for effecting multiple skin tests simultaneously on spaced portions of the skin of a nonplanar part of the human body is provided by a plurality of multiple-point pressure puncture heads each connected by an individual, relatively flexible, arm to a relatively rigid handle. In one form of device the points on the heads may be dipped into antigenic material. In a second form, each head has antigenic material preassembled on the multiple-point heads.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A device for effecting multiple skin tests simultaneously on spaced portions of a nonplanar body part comprising, in combination: a relatively rigid, elongated handle; a plurality of multiple-point, skin-puncturing heads located laterally outwardly of both longitudinal sides of the handle, so that the handle does not obstruct view of the puncturing heads when being used to effect skin tests; and a plurality of elongated connector means for connectinG the skin-puncturing heads to the handle; each connector means being of small size dimension relative to its length and being spaced from adjacent connector means so as not to obstruct view of the puncturing heads, each connector means extending longitudinally transversely to the longitudinal axis of the a handle and interconnecting at its distal end to one of the multiple-point heads so that the heads may all be pressured from the single handle to effect a plurality of multiple-point pressure puncture tests simultaneously on spaced portions of the skin of a nonplanar body part, the connector means extending outwardly and angling downwardly of the handle means so as to locate the multiple-point heads in a plane spaced substantially below the handle means.
Claim 2
Independent Claim
190 words
A device for effecting multiple skin tests simultaneously on spaced portions of a nonplanar body part comprising, in combination: a relatively rigid, elongated handle; a plurality of multiple-point, skin-puncturing heads located laterally outwardly of both longitudinal sides of the handle, so that the handle does not obstruct view of the puncturing heads when being used to effect skin tests; and a plurality of elongated connector means for connectinG the skin-puncturing heads to the handle; each connector means being of small size dimension relative to its length and being spaced from adjacent connector means so as not to obstruct view of the puncturing heads, each connector means extending longitudinally transversely to the longitudinal axis of the a handle and interconnecting at its distal end to one of the multiple-point heads so that the heads may all be pressured from the single handle to effect a plurality of multiple-point pressure puncture tests simultaneously on spaced portions of the skin of a nonplanar body part, the connector means extending outwardly and angling downwardly of the handle means so as to locate the multiple-point heads in a plane spaced substantially below the handle means.
Claim 3
Dependent Claim
43 words
A device as in claim 1 wherein each elongated connector means provides a mounting for the multiple-point skin-puncturing head that permits flexing of each connector means in a plurality of directions at the point of connection of the connector means to the handle.
Claim 4
Dependent Claim
26 words
A device as in claim 2 wherein each elongated connector means includes an elbow section intermediate the ends of the connector means to permit additional flexibility.
Claim 5
Dependent Claim
17 words
A device as in claim 1 wherein the handle, multiple-point heads and connector means are integrally molded.
Claim 6
Dependent Claim
44 words
A device as in claim 1 wherein each elongated connector means includes brace means in the plane of the connector means and at the point of connection to a multiple-pointed head so as to rigidify the connection of the head to the connector means.
Claim 7
Dependent Claim
60 words
A device as in claim 1 wherein the handle is an elongated barlike body having a greater height than width so as to have strength for transmitting vertically applied forces from the handle to all the multiple-point heads, while affording maximum visibility of the multiple-point heads during a test-applying operation and affording easy gripping of the handle by the fingers.
Claim 8
Dependent Claim
36 words
A device as in claim 6 wherein the connector means connect to the handle adjacent the lower edge thereof, and the multiple-point heads are located in a plane spaced below said lower edge of the handle.
