Patent number: 11896754Abstract: A wound dressing apparatus includes a wound dressing member dimensioned for positioning relative to a wound bed. The wound dressing member including an internal vacuum reservoir and has a port in communication with the vacuum reservoir for applying subatmospheric pressure to the vacuum reservoir to facilitate removal of fluid from the wound bed. The wound dressing member includes a visual pressure indicator associated therewith for indicating a level of pressure within the vacuum reservoir. The visual pressure indicator includes color indicia having a plurality of colors corresponding to a condition of the pressure within the vacuum reservoir. The wound dressing member includes a lower absorbent member positionable adjacent the wound bed and an upper member which at least partially defines the vacuum reservoir. At least one of the top member and the lower absorbent member has the visual pressure indicator mounted thereto.Type: GrantFiled: October 30, 2019Date of Patent: February 13, 2024Assignee: Smith & Nephew, Inc.Inventors: Kurt Haggstrom, E.

Patent number: 11737925Abstract: A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.Type: GrantFiled: March 18, 2022Date of Patent: August 29, 2023Assignee: Smith & Nephew, Inc.Inventors: Kurt Haggstrom, Alain Tranchemontagne, Loredana Jinga
