Definitions

  • a kit for treating a tissue site may comprise a dressing comprising a contact layer having a tacky surface, a release layer, and a package layer.
  • the release layer may be positioned against the tacky surface of the contact layer, and the package layer may be positioned adjacent a surface of the contact layer opposite the tacky surface.
  • the release layer and the package layer may be joined around a perimeter of the contact layer to provide a sterile compartment around the contact layer.
  • the contact layer may comprise a hydrophobic gel, which may further comprise a plurality of apertures.
  • the release layer may comprise an outer film layer comprising a transparent material and an inner layer comprising a material adapted to assist with heat sealing a perimeter edge of the release layer to a perimeter edge of the package layer.
  • a dressing kit may comprise a dressing and a pouch.
  • the dressing may include a first layer comprising a hydrophobic gel, a second layer comprising a polymer film, and a third layer coupled to the second layer opposite the first layer, wherein the third layer comprises a polymer drape having an adhesive disposed on a first side.
  • the pouch may include a release layer and a package layer.
  • the release layer may be coupled to the first layer of the dressing opposite the second layer of the dressing, wherein the release layer is adapted to be peeled away from the first layer.
  • the package layer may be positioned adjacent the third layer of the dressing. A perimeter edge of the release layer and a perimeter edge of the package layer may be joined so that the pouch forms a sealed compartment around the dressing.
  • Figures 6A-6D are schematic diagrams showing additional details that may be associated with the use of a dressing kit incorporating an example embodiment of a tissue interface, according to some illustrative embodiments.
  • Figure 7 is a functional block diagram of an example embodiment of a therapy system that can provide negative-pressure treatment in accordance with this specification.
  • each of the apertures 245 may have uniform or similar geometric properties.
  • each of the apertures 245 may be circular apertures, having substantially the same diameter.
  • the diameter of each of the apertures 245 may be between about 1 millimeter to about 50 millimeters. In other embodiments, the diameter of each of the apertures 245 may be between about 1 millimeter to about 20 millimeters.
  • geometric properties of the apertures 245 may vary.
  • the apertures 245 disposed in the periphery 235 may have a diameter between about 9.8 millimeters to about 10.2 millimeters.
  • the apertures 245 disposed in the corners 250 may have a diameter between about 7.75 millimeters to about 8.75 millimeters.
  • the release layer 120 may be, for example, a transparent layer, and may be a multilayer film comprising a base film 292 coextruded with an inner layer 294.
  • the material of the inner layer 294 may aid with heat sealing an inner surface of the release layer 120 to an inner surface of the package layer 130 around the dressing 110.
  • the base film 292 may comprise a polyamide or polyester film
  • the inner layer 294 may comprise a low melting-point ionomer-type material.

  • the first layer 220 and the second layer 225 can also substantially reduce or prevent exposure of tissue to the third layer 230, which can inhibit growth of tissue into the third layer 230. If the supply of negative pressure is discontinued, the pressure differential across the fluid restrictions 270 can dissipate, allowing the fluid restrictions 270 to move to their resting state and prevent or reduce the rate at which exudate or other liquid can return to the tissue site through the second layer 225 of the tissue interface 210.
  • the first layer 310 may be a contact layer or sealing layer comprising or consisting essentially of a soft, tacky material suitable for being placed in contact with a tissue site and potentially providing a fluid seal with a tissue site, and may have a substantially flat surface.
  • the first layer 310 may comprise, without limitation a silicone gel, a soft silicone, hydrocolloid, hydrogel, polyurethane gel, polyolefin gel, hydrogenated styrenic copolymer gel, a foamed gel, a soft closed cell foam such as polyurethanes and polyolefins coated with an adhesive, polyurethane, polyolefin, or hydrogenated styrenic copolymers.
  • FIG 4 is an assembly view of another example of a dressing kit 100, illustrating additional details that may be associated with some embodiments.
  • the dressing kit 100 may comprise an example embodiment of the dressing 110, the release layer 120, and the package layer 130 of the pouch 105 of Figure 1.
  • the dressing 110 may comprise a tissue interface 210, which may comprise a first layer 410 and a second layer 420 disposed adjacent to the first layer 410.
  • the first layer 410 and the second layer 420 may be stacked so that the first layer 410 and the second layer 420 are in contact with each other.
  • the first layer 410 may be in the form of a contact layer for being positioned against a tissue site.
  • Figures 6A-6D are schematic diagrams illustrating some aspects of the use of a dressing kit 100, according to some example embodiments. More specifically, Figure 6 A shows an initial state 605 of a dressing kit 100, which may include a tissue interface 210 provided within a sealed pouch 105.
  • the tissue interface 210 may include a first layer 610 comprising a perforated silicone film laminated to a second layer 615 comprising a foam.
  • the first layer 610 may be adhered to the inner surface of a release layer 120 of the pouch 105.
  • the dressing kit 100 may in some instances be used as part of, or in conjunction with, therapy systems configured to deliver negative pressure therapy to one or more tissue sites.
  • a dressing kit 100 may be used for supplying the dressing or dressing material that is applied to the tissue site for use with a negative-pressure therapy system. Since it is often desirable for dressings to include a tacky tissue-facing surface, the disclosed packaging layers of the dressing kit 100 may protect such tacky surfaces prior to application to the tissue site and use with the negative-pressure therapy system.

Abstract

L'invention concerne des pansements et des kits de pansements à emballage intégré, qui peuvent comprendre un pansement comprenant une couche de contact ayant une surface collante et un emballage ayant une première couche d'emballage et une seconde couche d'emballage. La première couche d'emballage peut être positionnée contre la surface collante de la couche de contact et la seconde couche d'emballage peut être positionnée adjacente à une surface de la couche de contact opposée à la surface collante. La première couche d'emballage et la seconde couche d'emballage peuvent être jointes autour d'un périmètre de la couche de contact pour former un compartiment stérile scellé autour de la couche de contact. Dans certains modes de réalisation, le pansement peut comprendre des couches de film supplémentaires et/ou d'autres couches de collecteur.
