A fluorescent oxygen sensing ink includes at least one organic solvent, at least one polymer binder disposed in the organic solvent, and an oxygen-sensitive fluorescent dye disposed in the organic solvent. The oxygen-sensitive fluorescent dye and the at least one polymer can interact to form a moisture-resistant film. The fluorescent oxygen sensing ink can be incorporated into an oxygen sensing wound dressing.

The current invention describes a method for developing bioactive borate glass (BBG)-hydrogel constructs based on 3D printing technology for healing of burn wounds and low-tomoderate exuding wounds. The hydrogels serve as a water reservoir and binder for BBG, to provide hydration of the BBG-hydrogel construct and to make the bioink printable, while 3D printing technology enables the layer-by-layer deposition of multiple materials including BG and hydrogels such as alginate, gelatin, GelMa, cellulose, chitosan and other like materials, as well as control of pore geometry to increase the available surface area for wound-dressing contact and more favorable cell-biomaterial interactions.

A vented wound dressing barrier includes one or more membrane layers with a plurality of vents. The vents are cut along a perimeter of the vents through the one or more membrane layers. Each vent having a connection portion uncut relative to the one or more membrane layers thereby forming a hinge configured to allow the vents to open for drainage when exposed to fluid underlying the vented wound dressing barrier. The plurality of vents is each cut along the perimeter without removal of any of the membrane layer. The one or more membrane layers with the plurality of vents has a surface for covering a wound, the surface area in the absence of a fluid pressing on the vents having no openings or voids which reduce the surface area of a vented wound dressing barrier area covering a wound.

An open-cavity, reduced-pressure treatment device and system for treating a cavity in a patient's body, such as an abdominal cavity, is presented. In one instance, an open-cavity, reduced-pressure treatment device includes a plurality of encapsulated leg members, each having an interior portion with a leg manifold member and formed with fenestrations operable to allow fluid flow into the interior portion, and a central connection member fluidly coupled to the plurality of encapsulated leg members. The central connection member has a connection manifold member. The open-cavity, reduced-pressure treatment devices, systems, and methods allow for, among other things, removal of fluids.

Methods and apparatuses are disclosed relating to the creation and use of bespoke wound fillers and other wound treatment apparatuses. Some embodiments provide for the creation of bespoke wound fillers based on characteristics of a wound. Certain embodiments also include the use of bespoke wound fillers in combination with negative pressure to treat a wound.

The invention relates to a unit for hemostasis. The unit is configured to be directly applied to a bleeding wound and comprises an envelope enclosing an inner space as well as an effective amount of a hemostatic material disposed within the inner space. Furthermore, the invention relates to an arrangement of two or more such units for hemostasis, the units being coupled to each other. Moreover, the invention relates to a method for producing an arrangement of units for hemostasis. In accordance with the method, an effective amount of a hemostatic material is disposed within an interior region of a starting material, and neck regions are formed on both sides of the charge so as to form an envelope enclosing the charge.

A system for providing reduced-pressure treatment to a moveable tissue site, such as a joint, includes a flexible dressing bolster. The flexible dressing bolster has a first side and a second, inward-facing side, and a plurality of flexion joints formed on the flexible dressing bolster. The system further includes a sealing subsystem for providing a fluid seal over the flexible dressing bolster and the patient's epidermis and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The sealing subsystem and reduced-pressure subsystem are operable to deliver a reduced pressure to the moveable tissue site. The flexible dressing bolster is operable to allow articulation or movement of the moveable tissue site. The sealing subsystem may include a drape with folds. Other systems, apparatuses, and methods are presented.

Systems, methods, and apparatuses for treating a tissue site are described. In some embodiments, the system may include a pouch having an upstream layer, a downstream layer, and an absorbent member enclosed between the upstream layer and the downstream layer. The upstream layer and the downstream layer may each include a hydrophobic side and a hydrophilic side. The hydrophilic side of both the upstream layer and the downstream layer may be positioned facing the absorbent member. The hydrophobic side of both the upstream layer and the downstream layer may form a portion of an exterior surface of the pouch such that fluid incident on the pouch is distributed laterally along the exterior surface of the pouch before being absorbed by the absorbent member.

A penile condom catheter facilitates urine collection and egress of urinary fluids away from the body torso. A circumferential anchoring structure includes a web of flexible strands sized and arranged to at least partially contact a portion of the penis. The anchoring structure provides a flexible yet secure hold against the penis when flaccid and provides an increase in the hold when a longitudinal force is exerted upon the anchoring structure. An annularly circumferential penile skin covering material is affixed to the anchoring structure and sized to fit over at least a portion of the penis. A seal is affixed to at least a portion of a covering material, a covering material orifice, or an anchoring structure. A conduit is affixed to at least one of a covering material, a covering material orifice, a seal and an anchoring structure created to permit the flow of urinary fluid away.

An anisotropic wound drape for treating a wound on a patient includes a flexible sheet for placing over a tissue site. The flexible sheet includes a first isotropic zone, and a second isotropic zone. The first isotropic zone and the second isotropic zone are configured to provide the flexible sheet with anisotropic stretching properties. The anisotropic drape may used as part of a reduced-pressure wound treatment system. Other systems and methods are also presented.
