A medical dressing, specifically adapted to comprise a machine-readable tag for allowing efficient and safe inspection during use of the medical dressing is described. A medical dressing arrangement and to a computer implemented inspection method applied in conjunction with the medical dressing is also described.

One aspect of the present disclosure is directed to a device for providing light to the surface of a subject, comprising an array of a plurality of light emitting modules, wherein the plurality comprises four light emitting modules, each module of the plurality is flexibly connected to another module of the plurality, and two of the modules of the plurality comprise a polygonal perimeter having 4, 5, or 6 major sides, a light source, and a longest apex-to-apex dimension for a module of 5-50 millimeters, and, optionally, a non-adherent member configured to be adjacent to the subject.

The disclosed technology relates to materials for the detection of wounds, e.g., chronic wounds or infected wounds, including compositions, substrates, kits, dressing materials, and articles, and systems containing such compounds. The disclosed technology further relates to methods of using these compositions, kits and systems in the diagnosis and/or detection of chronic or infected wounds based measurement of pH. Additional disclosure relates to methods of characterizing wounds based on pH of wounds or wound fluids and using such information to treat, manage, and follow-up patients suffering from chronic or infected wounds.

In-vivo fluid monitoring devices and methods are disclosed herein. An example device is configured for patients which monitors increases and decreases of fluid retention in patients with various clinical conditions such as heart and renal failure pre-operation and post operation thus allowing physicians to more accurately detect said fluid retention gains through a mechanism directly or indirectly connected to circulatory stocking which act as a conduit to detect said fluid changes through skin electrolysis and alterations respective to fluid changes directly corresponding with galvanic skin response measurement changes.

A conduit for treating a tissue site with reduced pressure may include a primary lumen and at least one secondary lumen. A wall of the conduit may include a first wall material and a second wall material. The first wall material may comprise a substantially non-absorbent material that is vapor impermeable and liquid impermeable. The second wall material may comprise an absorbent material that is vapor permeable and liquid impermeable. The second wall material may be positioned in fluid contact with the at least one secondary lumen. Other systems, apparatus, and methods are disclosed.

A light therapy apparatus includes a pad comprising at least a first layer and a second layer and a side scattering light guide mounted between the first layer and the second layer and having a first end and a second end. The first end and the second end extend in parallel with each other externally from the pad, the side scattering light guide extends from at least one of the first end or the second end in a sinusoidal shape or an inward extending circular spiral between the first layer and the second layer, and at least one of the first layer or the second layer is translucent.

The present invention relates to apical wound debridement methods for wound healing by altering the geometry of the wound. Further, the methods of the invention enhance wound healing, either when used alone or in combination with STERIS trips or other wound healing grafts and medical devices. Further, use of the methods of the present invention on various locations such as but not limited to the foot, ankle, leg, back, neck, arms, hands and face results in wound recovery.

In some embodiments, a wound monitoring and/or therapy apparatus includes a wound dressing configured to be positioned in contact with a wound, the wound dressing comprising one or more sensors configured to obtain measurement data of at least one of the wound or periwound. The apparatus can also include a controller configured to maintain a device clock indicative of a non-real time clock, receive measurement data obtained by the one or more sensors, and transmit measurement data to a remote computing device according to a security protocol, the security protocol comprising including the device clock associated with the measurement data in the transmission.

Provided herein is a system and method for coupling a wearable therapy system to a dressing and detaching the wearable therapy system from the dressing. One aspect provides a system including a drape with a switchable adhesive layer and a therapy system adhered to the drape via the switchable adhesive layer. The therapy system includes one or more radiation sources that can emit radiation wavelengths (e.g., light or electromagnetic waves) to impinge upon the adhesive and deactivate the adhesive when it is desired to remove the therapy system from the drape.

A system for analyzing a wound fluid. The system includes a transparent layer, a membrane layer, and an indicator layer that contains a colorimetric or fluorescent indicator reagent for detecting pH, a nitrite, an enzyme, a reactive oxygen species, a reactive nitrogen species, a nucleic acid, or a combination thereof. The membrane layer is impermeable to blood clots and cellular debris and is permeable to wound fluid. Also provided are methods for analyzing a wound fluid and for detecting biological fluid on biomedical instruments and waste materials using the system.
