Disclosed embodiments relate to apparatuses and methods for a skin perfusion pressure determination device. In some embodiments, a skin perfusion pressure determination device can include a sensor module having a first sensor for sensing a first parameter associated with a pressure exerted on a target area by the sensor module and a second sensor for sensing a second parameter associated with an amount of blood perfusion at the target area. In some embodiments, the first sensor and the second sensor can be arranged such that, when the sensor module is pressed against the target area the first sensor produces an output corresponding to the sensed first parameter and the second sensor produces an output corresponding to the sensed second parameter.

Bacteria-responsive core-shell nanofibers and a process for the preparation thereof are described. The nanofibers release of an antibacterial agent in response to the presence of bacteria. The core of the nanofiber comprises a biocompatible polymer together with an antibacterial agent such as a quaternary ammonium compound, for example benzyl dimethyl tetradecyl ammonium chloride (BTAC). Surrounding the core is shell comprised of a bacterially degradable polymer, which is susceptible to break-down by bacterial enzymes such as lipase, or to acidic pH conditions. The shell may comprise, for example, polycaprolactone (PCL) and poly(ethylene succinate) (PES). The nanofibers may be incorporated into wound dressings.

A natural peptide comprising a cellular growth promoting fragment of a protein selected from SEQ ID NOs: 1 to 13, and a composition comprising a plurality of growth promoting peptides, is described. Also disclosed is the use of the peptides and compositions in prevention of ageing of human skin, treatment of diseases or conditions characterised by damaged epithelial cells or tissue such as colon cancer and peripheral inflammatory disorders, and wound treatment. Specific pea and rice protein derived peptides are described in SEQ ID NOs: 15 to 505, and 546 to 704.

A bandage system lances a skin tag from a person's body and thereafter projects the wound created. The system has a base layer that is adhesively attached to the person such that the skin tag passes through an opening of the base layer. A cutter is located atop the base layer and uses a pair of blades that are squeezed together to cut the skin tag protruding through the opening. After cutting, a protective layer is adhered to the base layer such that a medicine laden absorbent pad on the protective layer overlays the opening on the base layer absorbing any blood from the wound and applying the medicine to the wound. Thereafter, the system is worn as a typical bandage.

A method, performed in an accessory device, for communicating the operating state of a wound dressing comprising an absorbent core layer is disclosed, wherein the accessory device comprises an interface configured to communicate with one or more devices of a wound dressing system, the one or more devices comprising a monitor device, and/or a wound dressing configured to be placed on a skin surface of a user, the method comprising: obtaining monitor data from the one or more devices, the monitor data being indicative of a condition of the wound dressing; determining an operating state of the wound dressing based on the monitor data, wherein the operating state is indicative of a degree of wetting of the absorbent core layer of the wound dressing; and communicating the operating state of the wound dressing via the interface.

A wound dressing is disclosed. A wound dressing comprises a first adhesive layer, an electrode assembly, a monitor interface and a multiplexer. The first adhesive layer comprises a proximal surface configured for attachment of the wound dressing to a skin surface of a user. The electrode assembly comprises a plurality of electrodes including a first set of first electrodes. The monitor interface is configured to form a mechanical and electrical connection with a monitor device. The monitor interface comprises a coupling part and a plurality of terminals including a first terminal. The multiplexer comprises a number of N input pins and a number of M output pins. The N input pins include a first set of first input pins for connection to first electrodes of the first set of first electrodes, the first set of first pins including a first primary input pin and a first secondary input pin, and the M output pins include a first output pin. The first primary input pin is connected to a first primary electrode of the first set of first electrodes and the first secondary input pin is connected to a first secondary electrode of the first set of first electrodes, and the first output pin is connected to the first terminal of the monitor interface. The multiplexer is configured to connect the first primary input pin to the first output pin in a first multiplexer configuration and to connect the first secondary input pin to the first output pin in a second multiplexer configuration.

A surgical recovery process for improving the adhesion of the skin to substrate after procedures such as liposuction. A kinetic tape is adhered outside of the surgical area and then stretched along a midline of the abdomen over the rectus abdominis muscles and then adhered to the skin to pull the skin into a better position for healing. Additional segments of kinetic tape are similarly anchored to the skin outside of the surgical area to pull skin over the side muscles of the abdomen. The kinetic tape remains applied for a period of days and may optionally be reapplied to be continually refined the healing process.

Disclosed herein are wound bandages that employ electromagnetic elements to accelerate wound healing and therefore reduce the time that such bandages must be worn. In embodiments, a wound bandage can include self-contained electromagnetic circuitry that can be energized to provide low frequency electromagnetic energy to a wound while the bandage is worn over the wound to promote wound healing.

The present invention relates to a wound volume measuring method and device, wherein the method comprises the steps of: disposing a foam dressing on a wound site; hermetically sealing the wound site by attaching a film dressing on skin adjacent to the wound site; supplying a negative pressure to the hermetically sealed space formed between the film dressing and the wound site, and thereby discharging fluid into the hermetically sealed space; measuring the flow of the fluid discharged from the hermetically sealed space; and calculating the volume of the wound site on the basis of the measured fluid flow.

A system for subatmospheric pressure therapy in connection with healing a wound is provided. The system includes a wound dressing cover dimensioned for positioning relative to a wound bed of a subject to establish a reservoir over the wound bed in which subatmospheric pressure may be maintained, a subatmospheric pressure mechanism including, a housing, a vacuum source disposed in the housing, and a collection canister in fluid communication with the vacuum source. The system further includes an exudate conduit in fluid communication with the wound dressing and the collection canister for collecting exudate removed from the reservoir and deposited in the collection canister under influence of the vacuum source and a vent conduit in fluid communication with the collection canister and the wound dressing for introducing air into the reservoir to facilitate flow of exudate through the exudate conduit.
