Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 95 words
An adhesive bandage comprising: a. adhesive tape; b. an absorbent pad carried by the tape, which is smaller in its length than the tape; and c. a release sheet releasably attached to the tape on the side of the adhesive overlaying the whole pad; said release sheet having: d. a blister having an open side facing the pad; and e. a rupturable capsule containing a medicine therein, which is placed in the blister; said blister being more rupture-resistant than said capsule and serving to direct medicine from the capsule when ruptured onto said absorbent pad.
Claim 2
Dependent Claim 95 words
An adhesive bandage comprising: a. adhesive tape; b. an absorbent pad carried by the tape, which is smaller in its length than the tape; and c. a release sheet releasably attached to the tape on the side of the adhesive overlaying the whole pad; said release sheet having: d. a blister having an open side facing the pad; and e. a rupturable capsule containing a medicine therein, which is placed in the blister; said blister being more rupture-resistant than said capsule and serving to direct medicine from the capsule when ruptured onto said absorbent pad.
Claim 3
Dependent Claim 14 words
An adhesive bandage claimed in claim 1, wherein the capsule is made from gelatin.
Claim 4
Dependent Claim 31 words
An adhesive bandage claimed in claim 1, wherein the medicine is dissolved into or suspended in a vegetable oil selected from the group substantially consisting of sesame, peanut and olive oil.
Claim 5
Dependent Claim 23 words
An adhesive bandage claimed in claim 1, wherein the blister portion is designed in a form of superior arc or modified superior arc.
Claim 6
Dependent Claim 22 words
An adhesive bandage claimed in claim 1, wherein the capsule is designed in a form of sphere, cylinder, cone or square column.
Claim 7
Dependent Claim 20 words
An adhesive bandage claimed in claim 1, wherein the release sheet is provided with a slit at one end thereof.
Claim 8
Dependent Claim 16 words
An adhesive bandage claimed in claim 1, wherein the blister portion and/or the capsule is transparent.
Claim 9
Dependent Claim 159 words
An adhesive bandage storable with a non-medicated pad which can be easily and simply converted to a medicated pad prior to application of the bandage to a wound; said adhesive bandage comprising: a. adhesive tape having an adhesive side and an adhesive-free side; and b. an absorbent pad carried by the tape on the adhesive side thereof; and c. a release sheet releasably attached to the tape on the adhesive side thereof; said release sheet having: d. a blister having an open side facing the pad; and e. a rupturable capsule in the blister; and f. free-flowing medicine in the capsule; wherein the blister is more rupture-resistant than is the capsule such that application of pressure on the outside of the blister causes the capsule to rupture and further causes the medicine to leave the capsule through the rupture and the open side of the blister to impregnate the pad thereby converting the non-medicated pad to a medicated pad.
Claim 10
Dependent Claim 159 words
An adhesive bandage storable with a non-medicated pad which can be easily and simply converted to a medicated pad prior to application of the bandage to a wound; said adhesive bandage comprising: a. adhesive tape having an adhesive side and an adhesive-free side; and b. an absorbent pad carried by the tape on the adhesive side thereof; and c. a release sheet releasably attached to the tape on the adhesive side thereof; said release sheet having: d. a blister having an open side facing the pad; and e. a rupturable capsule in the blister; and f. free-flowing medicine in the capsule; wherein the blister is more rupture-resistant than is the capsule such that application of pressure on the outside of the blister causes the capsule to rupture and further causes the medicine to leave the capsule through the rupture and the open side of the blister to impregnate the pad thereby converting the non-medicated pad to a medicated pad.
Claim 11
Independent Claim 170 words
A method of painlessly applying an adhesive bandage to a wound while avoiding decrease in efficacy of the medicine during prior storage; said method comprising: I. providing an adhesive bandage comprising: a. adhesive tape; and b. an absorbent pad carried by the tape; and c. a release sheet releasably attached to the tape on the side of the adhesive; said release sheet having: d. a blister having an open side facing the pad which open side is capable of receiving a pressure-rupturable capsule containing a medicine; and then II. inserting the capsule into the blister; and then III. applying pressure to the pressure-rupturable capsule to release the medicine while confining the medicine to the blister while causing the medicine to leave the blister through its opened end and impregnate the pad thereby forming a freshly-impregnated, medicated pad; IV. detaching the release sheet from the adhesive tape prior to application of the adhesive bandage to the wound; and V. painlessly applying the adhesive bandage with freshly-impregnated, medicated pad to a wound.
Claim 12
Independent Claim 170 words
A method of painlessly applying an adhesive bandage to a wound while avoiding decrease in efficacy of the medicine during prior storage; said method comprising: I. providing an adhesive bandage comprising: a. adhesive tape; and b. an absorbent pad carried by the tape; and c. a release sheet releasably attached to the tape on the side of the adhesive; said release sheet having: d. a blister having an open side facing the pad which open side is capable of receiving a pressure-rupturable capsule containing a medicine; and then II. inserting the capsule into the blister; and then III. applying pressure to the pressure-rupturable capsule to release the medicine while confining the medicine to the blister while causing the medicine to leave the blister through its opened end and impregnate the pad thereby forming a freshly-impregnated, medicated pad; IV. detaching the release sheet from the adhesive tape prior to application of the adhesive bandage to the wound; and V. painlessly applying the adhesive bandage with freshly-impregnated, medicated pad to a wound.
Claim 13
Dependent Claim 83 words
An adhesive bandage comprising: a. adhesive tape; b. an absorbent pad carried by the tape, which is smaller in its length than the tape; c. a release sheet releasably attached to the tape on the side of the adhesive overlaying the whole pad; said release sheet having; d. a blister having an open side facing the pad, and e. a rupturable capsule containing a medicine therein, which is placed in the blister; and f. a screen interposed between the pad and the capsule.
Claim 14
Dependent Claim 83 words
An adhesive bandage comprising: a. adhesive tape; b. an absorbent pad carried by the tape, which is smaller in its length than the tape; c. a release sheet releasably attached to the tape on the side of the adhesive overlaying the whole pad; said release sheet having; d. a blister having an open side facing the pad, and e. a rupturable capsule containing a medicine therein, which is placed in the blister; and f. a screen interposed between the pad and the capsule.
