  • Publication number: 20200383836
    Abstract: A medical dressing is described for prevention of pressure ulcers. The dressing has a gel pad having a low compressive strength; i.e. from 5 kPa to 60 kPa at a strain of 50%, as measured by the compression test described herein. The dressing reduces the shear and compression forces on the skin and in the underlying the soft tissue layers and prevents or mitigates the onset of pressure ulcers.

  • Patent number: 10744225
    Abstract: 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.
