  • Patent number: 9592656
    Abstract: A seal formed of laminated films adhered to a peel strip. The seal includes a target area free of adhesive, and adhesive surrounding the target area. The seal is formed so that the target area is visually distinguished from the surrounding adhesive to facilitate accurate placement of the seal on a medical container by a user. The use of a large adhesive dot pattern enhances the peripheral edge of each adhesive dot to provide a prominent and visual lattice. The prominent and visual lattice distinguishes the adhesive areas of the seal from the non-adhesive areas. The lattice boundary surrounding each adhesive dot is still prominent and visible when a clear and transparent adhesive is applied to selected surfaces of the seal.

  • Patent number: 8920590
    Abstract: A seal formed of laminated films adhered to a peel strip. The seal includes a target area free of adhesive, and adhesive surrounding the target area. The seal is formed so that the target area is visually distinguished from the surrounding adhesive to facilitate placement of the seal on a medical container by a user. The use of a colored adhesive, reflectivity of the adhesive, a colored laminate, or a colored target background can be utilized to make the target area visually different from the surrounding adhesive.

  • Patent number: 8002113
    Abstract: A medical seal dispenser having a container molded of plastic and having clamshell portions hinged together. The clamshell portions of the container can be locked together when in a closed position. One clamshell portion includes a core holder for holding a roll of medical seals. The core holder includes speed bumps that are raised or domed protrusions on the core holder to provide rolling friction to the roll of medical seals during dispensing. This controlled rotation of the roll prevents spooling if the carrier strip is pulled out of the container too quickly.

  • Patent number: 4638796
    Abstract: A method for dressing wounds to prevent adherence of the covering dressing to the wound includes applying a surfacing barrier (20) as an interpositional material between the wound and covering dressing. The barrier is an extruded, nonwoven polymeric material permeable to blood and serum and having an air permeability between about 300 and about 1140 ft..sup.3 /min./ft..sup.2 and a thickness of between about 0.5 mils to about 3.0 mils. The barrier is positioned over the wound and surrounding area and conformed to the shape of the body being treated. The covering dressing is then applied over the barrier.
