A phototherapy device, system, and method for treating acne and/or acne scarring, includes a light emitting device configured and arranged to emit light from a bottom surface thereof; and an attachment portion having an aperture therethrough configured to permit light through. The attachment portion is configured to retain the device to a user's skin and bathe the skin with phototherapeutic light from the light emitter. Attachment of the device may be preceded with the application of synergistic fluid, ointment, gel, cream, lotion, foam, soap, or other solutions which may or may not consist of known topical acne treatment agents, augment device attachment to the skin, and/or have photodynamic properties. The light emitted may be any wavelength, combinations of wavelengths, intensity, pulse frequency, and exposure duration.

This disclosure relates to a wound care device which contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device contains a perforated adhesive layer.

A dressing for treating a tissue site with negative pressure may include a first layer having a first side, a second side, and fenestrations having a raised edge extending from the first side. The raised edge is configured to expand in response to a pressure gradient across the first layer. The dressing also includes a second layer adjacent to the first side. The second layer includes a manifold. The dressing also includes a cover coupled to the second layer opposite the first layer. The cover includes a polymer drape.

Disclosed embodiments relate to wound care materials and methods that comprise a self-gelling composition, configured to form a gel upon contacting fluid. The self-gelling composition is a substantially homogeneous mixture, and comprises fluid-absorbent particles loaded with iodine-based antimicrobial agent, a dehydrated hydrogel powder, and a polymer base, configured to allow dispensing the self-gelling composition from a syringe or tube and to prevent the self-gelling composition from gelling prior to contacting fluid. The gel performs one or more of the following tasks during a wear time, when applied at the wound: absorbing fluid or exudate, releasing iodine-based antimicrobial agent, achieving antimicrobial activities at the wound, remaining structurally integral and cohesive, protecting the wound from exposure to microorganisms, and facilitating healing. After a wear time of at least three days, the gel can be removed in two pieces or less and leave less than 5% residue by weight.

Devices and methods herein remove water from human or animal biological waste fluids using one or more forward osmosis filters. The devices allow for the volume of liquid or semi-liquid waste, including potentially infectious liquid waste, to be filtered to reduce potential exposure of healthcare staff to infectious liquid waste. On a hospital, healthcare staff, or individual patient basis, removing water and concentrating the waste can reduce challenges in management and disposal of the waste. Devices herein use forward osmosis to manage and filter, using one or more suitably sized filter(s), biological fluid exudate from wounds. The devices can be constructed to transport water present in the exudate away from a wound. The wound treatment devices herein not only allow for fluid from wounds to be filtered but also provide structures that can protect wounds from external contaminants, including bacteria and viruses. The wound treatment devices can be incorporated into negative pressure wound therapy systems, if desired.

A medical dressing is described having a substrate with a first chemical compound, said substrate having a first surface, wherein said medical dressing further includes an adhesive layer having a skin-facing surface to adhere said medical dressing to a dermal surface, wherein at least a portion of said skin-facing surface has a coating with a second chemical compound. Also described is a method of manufacturing such a medical dressing.

A dressing for negative pressure wound therapy includes an absorbent layer comprising a gelling absorbent material for absorbing exudate, a peripheral adhesive skin contact layer comprising a hydrocolloid adhesive and defining a window through which the absorbent layer is able to contact a wound, and a cover layer that is water impermeable and air permeable. The cover layer defines an aperture to be used with a pump assembly to provide negative pressure to a wound site.

An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.

Wound dressings displaying improved adhesion and breathability and methods for their manufacture, the wound dressing comprising a backing layer, a layer of pressure-sensitive adhesive and a perforated layer of silicone gel, wherein the layer of pressure-sensitive adhesive is disposed between the substrate and the perforated layer of silicone gel, and wherein the layer of pressure-sensitive adhesive is moisture-permeable.
