Abstract: The present disclosure is directed to transparent, flexible substrates and, in particular, moisture-absorbing substrates for use in wound healing and wearable bioelectronics. Substrates of the present application can be formulated and used as wound dressings, electrodes, and electroceutical devices. Advantageously, in some aspects, substrates of the present application can absorb moisture (e.g., wound exudate, apocrine sweat, eccrine sweat), without swelling while also remaining transparent even with moisture absorption. In other aspects, substrates of the present application can be formulated to exhibit superior mechanical and electrical properties for application to a wide array of bioelectronic applications.

Abstract: 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.

Abstract: A wound therapy apparatus is disclosed herein. In various aspects, the wound therapy apparatus may include a distal layer to contact a wound bed, the distal layer comprised of silicone, and fenestrations disposed about the distal layer pass between a distal side of the distal layer and a proximal side of the distal layer to communicate between the distal side and the proximal side. A pad may cooperate with the proximal side of the distal layer to receive exudate communicated through the distal layer from the wound bed via the fenestrations, in various aspects. Various materials including medicament(s) may be communicated to the wound bed through the distal layer via the fenestrations, in various aspects. A structural member may be included in various aspects to secure the distal layer and pad to a skin surface, in various aspects. Methods of use of the wound therapy apparatus are disclosed herein. This Abstract is presented to meet requirements of 37 C.F.R. § 1.72(b) only, and is not intended to identify key elements of the apparatus, methods, and compositions of matter disclosed herein or to delineate the scope thereof.

Abstract: Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

Abstract: The injection site multi-functional bandage includes a thin, flexible strip of support material with opposing upper and lower surfaces. The support material can be elongated with adhesive portions at opposing ends thereof. The adhesive portions can be covered by a removable cover. A non-adhesive absorbent can be provided between the adhesive portions on the lower surface of the support material. A reservoir including sterilization liquid can be disposed above or below the absorbent. The reservoir can be positioned along a center portion of the support material. An opening can extend through a portion of the absorbent. The opening can be selectively sealable by a releasable flap.
