Claim 10

A bandage, comprising: a tape strip having a pressure-sensitive adhesive on a front surface thereof to secure the bandage on a patient; and an absorbent pad comprising a sheet of nonwoven fabric secured on said front surface of the tape strip, said sheet having an inner layer of substantially hydrophilic fibers, and an outwardly facing first surface layer of substantially hydrophobic fibers, said inner and surface layers being bonded together in substantially isolated highly compacted areas defining adjacent regions of substantially less compaction, said fabric being formed in a repeating series of wave-like undulations substantially throughout the dimensions of the fabric, with the interfiber spaces in said areas being substantially closed, and with the interfiber spaces in said regions being substantially open, said sheet having a central portion for facing the patient, and a pair of side portions extending from opposed sides of said central portion and folded intermediate said central portion and said tape strip.

Claim 11

The bandage of claim 7 wherein said side portions are secured to the adhesive on a central portion of said tape strip.

Claim 12

A bandage, comprising: a tape strip having a pressure-sensitive adhesive on a front surface thereof to secure the bandage on a patient; and an absorbent pad comprising a sheet of nonwoven fabric secured on said front surface of the tape strip, said sheet having an inner layer of substantially hydrophilic fibers, and an outwardly facing first surface layer of substantially hydrophobic fibers, said inner and surface layers being bonded together in substantially isolated highly compacted areas defining adjacent regions of substantially less compaction, said fabric being formed in a repeating series of wave-like undulations substantially throughout the dimensions of the fabric, with the interfiber spaces in said areas being substantially closed, and with the interfiber spaces in said regions being substantially open, said bandage including a smooth organic film covering an outer surface of said pad and having openings extending through the film.

Claim 13

A bandage, comprising: a tape strip having a pressure-sensitive adhesive on a front surface thereof to secure the bandage on a patient; and an absorbent pad comprising a sheet of nonwoven fabric secured on said front surface of the tape strip, said sheet having an inner layer of substantially hydrophilic fibers, and an outwardly facing first surface layer of substantially hydrophobic fibers, said inner and surface layers being bonded together in substantially isolated highly compacted areas defining adjacent regions of substantially less compaction, said fabric being formed in a repeating series of wave-like undulations substantially throughout the dimensions of the fabric, with the interfiber spaces in said areas being substantially closed, and with the interfiber spaces in said regions being substantially open, said bandage including a smooth organic film covering an outer surface of said pad and having openings extending through the film.
