Claim 7

adhesive on said one surface of said backing sheet member. 2. The laminated medicinal bandage according to claim 1 wherein said internal backing sheet member carries two calibrated scales spaced from each other, the calibration of each scale being different from the calibration of the other scale.

Claim 8

In a method for the topical treatment of angina pectoris and Raynaud's disease wherein nitroglycerin ointment is used locally to provide a systemic effect in the treatment, the improvement which consists of administering controlled quantities of nitroglycerin ointment to the skin or mucosa from a laminated medicinal bandage attached to the skin of a patient, said laminated medicinal bandage consisting of two layers: (a) the first layer comprising a backing sheet member having oppositely facing surfaces and predetermined perimeter dimensions and having a layer of adhesive on one of said surfaces thereof; (b) the second layer comprising: 1. an internal backing sheet member having predetermined perimeter dimensions less than those of said backing sheet member and having a calibrated scale on one surface thereof for accurate measurement of an ointment dosage applied thereto and adapted for contacting the skin, the surface of said internal backing sheet member opposite said one surface thereof being secured by said adhesive layer on said one surface of said backing sheet member extends about the perimeter of said internal backing sheet member between the respective perimeters of said internal backing sheet member and said first layer; and 2. an annular releasable backing layer covering said annular portion of said adhesive layer and surrounding the perimeter of said internal backing sheet member, said releasable backing layer and said internal backing sheet member being in the same plane and composed of the same material; (c) whereby said annular releasable backing layer may be removed and said bandage, with the ointment on said surface of said internal backing sheet member, secured in place on the skin by said annular portion of said adhesive on said one surface of said backing sheet member.

Claim 9

In a method for the topical treatment of angina pectoris and Raynaud's disease wherein nitroglycerin ointment is used locally to provide a systemic effect in the treatment, the improvement which consists of administering controlled quantities of nitroglycerin ointment to the skin or mucosa from a laminated medicinal bandage attached to the skin of a patient, said laminated medicinal bandage consisting of two layers: (a) the first layer comprising a backing sheet member having oppositely facing surfaces and predetermined perimeter dimensions and having a layer of adhesive on one of said surfaces thereof; (b) the second layer comprising: 1. an internal backing sheet member having predetermined perimeter dimensions less than those of said backing sheet member and having a calibrated scale on one surface thereof for accurate measurement of an ointment dosage applied thereto and adapted for contacting the skin, the surface of said internal backing sheet member opposite said one surface thereof being secured by said adhesive layer on said one surface of said backing sheet member extends about the perimeter of said internal backing sheet member between the respective perimeters of said internal backing sheet member and said first layer; and 2. an annular releasable backing layer covering said annular portion of said adhesive layer and surrounding the perimeter of said internal backing sheet member, said releasable backing layer and said internal backing sheet member being in the same plane and composed of the same material; (c) whereby said annular releasable backing layer may be removed and said bandage, with the ointment on said surface of said internal backing sheet member, secured in place on the skin by said annular portion of said adhesive on said one surface of said backing sheet member.
