A wound treatment apparatus is provided for treating tissue damage, which comprises a fluid impermeable wound cover sealed over a site for purposes of applying a reduced pressure to the site. The apparatus also can include a cover with protrusions on its surface for purposes of monitoring pressure at the site. One or more sensors can be positioned under the cover to provide feedback to a suction pump controller. The apparatus can have a miniature and portable vacuum source connected to the wound cover.

A pressure-sensing compression bandage having a plurality of pressure sensors provided to indicate the pressures applied by and/or the pressure gradient created by, the applied bandage at various locations along its length when the bandage is applied to a limb or other extremity.

A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.

Provided is a patch including at least one pressure-absorbing member, the pressure absorbing member formed of a resilient material and having at least a first surface, the at least first surface is configured with a plurality of projections extending therefrom and a plurality of channels crossing one another at a plurality of intersections, an outermost surface of said plurality of projections lies along a projections plane of the pressure-absorbing member, the projections being deformable when subjected to pressure applied to the patch, so as to absorb at least some of the applied pressure.

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 and a stabilizing structure that may aid in wound closure.

A method and apparatus for treating edema is disclosed. The method may include obtaining a compression garment comprising material having an end stretch. At least one gauge may be applied to the material. The compression garment may be applied to a patient. During the applying, the material may be stretched until the at least one gauge indicates that a proper amount of stretch has been reached. The at least one gauge may be tuned so that the material arrives at or near end stretch at substantially the same time that the at least one gauge indicates that the proper amount of stretch has been reached.

Disclosed is a marking method for marking a radiation therapy positioning note, comprising in sequence: a preparing step of providing a radiation therapy positioning sticker, wherein the radiation therapy positioning sticker includes a pattern layer and a release layer disposed on an outer surface of the pattern layer, and the radiation therapy positioning note is formed on the outer surface of the pattern layer; a transferring step of attaching the radiation therapy positioning sticker onto a predetermined note position of a radiation therapy target object in a manner that an inner surface of the pattern layer faces forward the predetermined note position and covers the predetermined note position; and a removing step of peeling off the release layer from the outer surface of the pattern layer to outwardly expose the radiation therapy positioning note, which is formed on the outer surface of the pattern layer covering the predetermined note position.

In some embodiments, a wound dressing that incorporates a number of sensors or sensors separate from the wound dressing can be utilized in order to monitor characteristics of a wound as it heals or to identify one or more risk factors or conditions that may precipitate a wound. In some implementations, a wound dressing configured to be positioned in contact with a wound includes a substantially flexible substrate supporting one or more sensors. The one or more sensors can include temperature sensors, conductivity sensors, multispectral optical measurements sensors, pH sensors, pressure sensors, colorimetric sensors, optical sensors, ultraviolet (UV) sensors, or infrared (IR) sensors.

Carefully coordinated patches having camouflaging and/or benefit properties can be formed for application to a desired region of human skin. The patches include a flexible film having a first, adhesive, outwardly facing major surface and a second outwardly facing surface which is textured to correspond to skin covered by the patch during use; wherein the flexible film further comprises at least one pigmented region and at least one region adapted to modify one or more optical properties selected from the group consisting of light transmission, light reflection, and light absorption. Methods of custom use of such patches may include 3D printing processes.

Wound therapy dressings are provided. The wound therapy dressings may include at least one selectively transparent layer with a refractive index in a range wherein interaction between the selectively transparent layer and fluids from a treatment site switches the selectively transparent layer from a first, opaque state to a second, transparent state. Dressings that include multiple layers may include polymer films with a plurality of fluid restrictions, a manifold, a transparent polymer drape, and a hydrophobic polymer layer. The dressings may further include negative pressure therapy treatment input devices. A method of use wherein the dressings are used to monitor fluid flow, exudate, and maceration around a treatment site is also provided.
