Patent number: 12059326Abstract: A medical dressing for prevention of pressure ulcers is described. The dressing has a backing layer, a pad, and a body contact layer, wherein the pad is arranged between the backing layer and the body contact layer. The body contact layer has an adhesive skin contact layer and an anisotropic layer having a first (x) direction and a second (y) direction perpendicular to the first (x) direction. The anisotropic layer is stiffer in the second (y) direction than in the first (x) direction. The dressing reduces shear and compression forces on the skin and in the underlying soft tissue layers and prevents the onset of pressure ulcers.Type: GrantFiled: December 13, 2018Date of Patent: August 13, 2024Assignee: Mölnlycke Health Care ABInventors: Patrick Rodzewicz, Linda Mårlind, Dennis Hansson, Karin Glasmästar, Anna Grou, Conny Jakobsson, Océane Lançon

Patent number: 10744225Abstract: A silicone foam is described that is produced in-situ at a wound site, e.g. in a wound cavity, through a multi-component system, based on a physical foaming process, wherein the gas required to form the foam structure is provided through a blowing agent independently of the curing reaction of polyorganosiloxane components of the multi-component system. Therefore, the blowing agent is provided as a distinct entity of the multi-component system that is, in particular, not the result of any chemical reaction taking place in the multi-component system. A device for producing the foam and the corresponding negative pressure wound therapy kit are also described.Type: GrantFiled: August 24, 2016Date of Patent: August 18, 2020Assignee: MÖLNLYCKE HEALTH CARE ABInventors: Lars Lindgren, Dennis Hansson, Shiva Eibpoosh
