Pressure Indicator

Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.

APPARATUSES AND METHODS FOR WOUND THERAPY

Some arrangements disclosed herein relate to devices and methods for treating a wound, comprising applying negative pressure to the wound through a cover applied over a wound, monitoring the internal pressure in the wound, and controlling the closure of the wound by controlling the amount that a wound packing material positioned under the cover collapses within the wound based on the monitored internal pressure. The wound packing material collapse can be controlled to ensure that the monitored internal pressure does not exceed a threshold value. Additionally, some embodiments or arrangements disclosed herein relate to a visualization element to visualize a location of a wound surface. The visualization element can comprise a radiopaque member that is configured to be positioned on or adjacent to a surface of an open wound.
