A protective dressing includes an outer dressing and an adhesive layer. The outer dressing includes an opening and a cavity sized to receive a phase-change material (PCM) insert inserted through the opening. The adhesive layer is configured to adhere to a patient's skin surrounding an anatomic site. When adhered to the patient's skin, the PCM insert modifies the patient's skin at the anatomic site. The PCM insert may be removed and replaced with another PCM insert. For example, a warm PCM insert may be replaced with a refrigerated PCM insert. The opening of the outer dressing may be self-sealing. The opening of the outer dressing may be sealed with an upper layer dressing coupled to the PCM cooling insert.
RE-CLOSABLE WOUND DRESSING WITH INCREASED ADHESIVE LAYER
A re-closable wound dressing is provided. A base layer is operable to be attached to a skin of a patient. The base layer forms a pre-fabricated aperture through which a wound of the patient is accessible. A cover layer is coupled with the base layer. The cover layer is operable to cover the pre-fabricated aperture, and is permanently adhered to the base layer along at least a portion of the cover layer. The base layer and the cover layer are made of like materials.
APPARATUSES AND METHODS FOR NEGATIVE PRESSURE WOUND THERAPY
Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.
IMPROVED WOUND DRESSING MEMBER
The present invention relates to an improved wound dressing member, characterized in that the improved wound dressing member is a laminate comprising: a main body having an opening formed in the central portion thereof, wherein the opening is operable and closable by means of a cover; a cover sheet laminated on top of the main body; a release paper laminated below the main body; and the cover sheet capable of opening or closing the opening by being form-fitted into the opening.

Wound dressing garment
A wound dressing garment is provided. The wound dressing garment includes a wearable garment including a portion having a hole configured to receive a wound dressing therein in combination with the wound dressing. The wound dressing includes a border connecting the wound dressing to the wearable garment where the border extends around the perimeter of the hole to locate the wound dressing therein. The wound dressing may include one or more additional layers including a hydrogel layer. A method for treating wound or preventing bed sores using the wound dressing garment is also provided.
Two-part bandage with replaceable wound covering portion
A two-piece bandage is useful for treating wound on a patient. The bandage includes a boundary portion including a bottom surface comprising adhesive for attaching the boundary portion to skin of a patient, an open window in the middle of the boundary portion permitting one to view a wound through the open window, and a top surface. The top surface includes a first portion of the top surface surrounding the open window including a flat surface and a second portion of the top surface including an uneven surface. The bandage further includes a plurality of replaceable wound covering portions, each replaceable wound covering portion comprising a padded section comprising a material to dress the wound.
Arithmetic coding for information related to sample adaptive offset processing
An image coding method includes: performing context arithmetic coding to consecutively code (i) first information indicating whether or not to perform sample adaptive offset (SAO) processing for a first region of an image and (ii) second information indicating whether or not to use, in the SAO processing for the first region, information on SAO processing for a region other than the first region, the context arithmetic coding being arithmetic coding using a variable probability, the SAO processing being offset processing on a pixel value; and performing bypass arithmetic coding to code other information which is information on the SAO processing for the first region and different from the first information or the second information, after the first information and the second information are coded, the bypass arithmetic coding being arithmetic coding using a fixed probability.
Self contained wound dressing with micropump
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.
Bandage which enables examining or treating a wound without removing the adhesive
The base of this bandaging system is attached to the skin around a wound by adhesive and supports the edges of the lid, which covers the wound and can easily be removed and replaced or re-used many times to facilitate examining or treating the wound while the base remains in place. The bandaging system has multiple embodiments to accommodate various situations. An embodiment with generally planar components is very simple but may cause vertical pressure on the skin near the wound when the lid is removed or attached. Such pressure is avoided by alternative embodiments in which the components have non-planar parts. Some embodiments have a hinge on an edge of the lid which allows the wound to be uncovered without detaching the lid. The components which latch lids to bases contribute to making the systems easy, quick, convenient, and comfortable to use.
