The present disclosure describes a wound dressing with one or more integrated pH sensors. The pH sensors can measure the pH at different portions of the wound and dressing. The pH sensors can measure the pH of the wound and dressing at different intervals throughout the wearing of the dressing. The pH sensors can provide real-time feedback during wear time. In addition to providing indications of pH, the pH sensors can provide indications of the wound dressing's level of saturation. The pH sensors can be visual indications that the wound dressing is saturated with fluid and should be changed.

There is provided improved therapy methods and apparatus for treating a patient's brain and spinal cord. The apparatus further relates to a flexible surgical balloon or cap-like device comprising one or more material layers that may have an antimicrobial element. The therapy apparatus may include portals for introducing diagnostic monitoring and/or therapeutic devices, and delivery of therapeutic drug delivery systems. Certain embodiments of the invention have an output emission area positioned to irradiate a portion of the brain with an efficacious power density and wavelength of light for diagnostic and/or therapeutic purposes.

A wound covering device for noncontact wound protection includes a shell and a coupler. The shell, which defines an interior space, has a bottom that is open so that the shell is configured to position over a wound in skin of a user. The coupler is coupled to the shell and is configured to removably couple to the skin of the user. The coupler is configured to retain the shell over the wound to protect the wound.

Provided herein is a system and method for trauma-free application and removal of light deactivated adhesive drapes. One aspect provides a system comprising a drape, at least one photosensitive adhesive portion having a release agent, and at least one acrylic and/or polyurethane adhesive portion, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a removable blocking layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing the removable blocking layer and applying light to the drape to deactivate the photosensitive adhesive portion and promote easy, clean, and less painful removal of the drape. When the photosensitive adhesive portion is deactivated, the acrylic and/or polyurethane adhesive portion maintains adhesion between the drape and the tissue until removal of the drape.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein. Some embodiments may further comprise one or more viewing windows disposed therethrough so as to enable monitoring or examination of fluids contained therein.

An enhanced adhesive bandage sandwich (FIG. 1) for compressing blood vessels and a kit for assembling said bandage sandwich. A bandage or kit can be used as a medicament, particularly, for use in treating varicose veins. A bandage sandwich or kit can be used to compress veins or arteries. A method to produce said bandage sandwich can include providing a first adhesive bandage layer; applying an elastic body to the first adhesive bandage layer; and applying a second adhesive bandage layer to the first bandage layer. The elastic body of the bandage sandwich can be shaped to follow the contours of veins or arteries to be compressed.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising a number of viewing portals that facilitate observation of wound tissue or healthy skin underlying the wound dressing. Some embodiments of the viewing portals are provided by forming through holes in internal dressing layers including absorbent material and transmission material, optionally by providing a plug material within the through holes, and by providing translucent or transparent cover layer and tissue contact layer materials.

An external protective interface is provided for intravenous infusion lines, drive lines, vacuum lines, and monitoring lines for percutaneous access. The interface acts as an airtight seal in concert with a vacuum line to promote accelerated tissue healing to reduce and prevent infection at insertion sites for infusion lines, drive lines, and medical devices. The interface provides additional mechanical stability to an implanted tube or PAD or so as to speed healing around a semi-permanent implanted tube or PAD, as well as connection points for vacuum lines and at least one drive line for the insertion of medical devices. The dense fibroblast ingrowth encouraged by the interface acts to strengthen barriers to infection at the insertion site.

A bandage comprising a base substrate, a wound covering portion, a first side coupling member and a second side coupling member, and a first side and second side adhesive portion. The base substrate includes a central region, a first side region and a second side region, and comprises an elastic member. The wound covering portion is positioned over the central region. The first side coupling member extends over the first side region. The second side coupling member extending over the second region. The first side adhesive portion is positioned on the first side region. The second side adhesive portion positioned on the second side region. A method of use as well as a protective carrier are likewise disclosed.
