Abstract: Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus includes a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus includes algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site.

Abstract: One implementation of the present disclosure is a negative pressure wound therapy (NPWT) system, according to some embodiments. In some embodiments, the system includes an instillation system configured to provide instillation fluid to a wound site, and a controller. In some embodiments, the wound site includes a wound and a wound dressing. In some embodiments, the controller is configured to provide a first quantity of instillation fluid for a first instillation cycle. In some embodiments, the controller is configured to determine a second quantity of instillation fluid for a second instillation cycle based on the first quantity and a reduction factor. In some embodiments, the second quantity of instillation fluid is less than the first quantity of instillation fluid. In some embodiments, the controller is configured to adjust an operation of the instillation system to provide the second quantity of instillation fluid to the wound site.

Abstract: This disclosure describes devices, systems, and methods related to two-piece dressings. In one aspect, a two-piece dressing includes a drape including a first light switchable adhesive, and a pad. The pad includes a second light switchable adhesive configured to couple the pad to the drape and a light source configured to emit light and activate at least the second light switchable adhesive. In another aspect a two-piece dressing includes a drape and a pad. The pad is configured to be coupled to the drape and to a light source, and the pad includes a light switchable adhesive configured to couple the pad to the drape. The light source is configured to emit light to activate the light switchable adhesive to decouple the pad from the drape, and the pad is configured to direct the light to activate second light switchable adhesive to decouple the drape from a tissue site.

Abstract: Some illustrative embodiments of an instillation assembly for treating a tissue site may include a fluid distribution lumen and a fluid hub that may define a fluid instillation pathway. The fluid distribution lumen may be defined by a first film layer and a second film layer, and the fluid hub may be positioned in fluid communication with the fluid distribution lumen. The instillation assembly may be used in combination with a reduced-pressure assembly that may define a reduced-pressure pathway separate from the fluid instillation pathway.

Abstract: A mobile device and method for using a mobile device to disinfect by eliminating bacteria, viruses, and pathogens is provided. The mobile device includes a disinfecting light emitting diode that emits UVC light only in the range of 200 nm to 220 nm to disinfect without harming human tissue. Disinfecting of an object or surface can be accomplished using the mobile device by turning on the LED to provide UVC light in a range of 200-220 nm and holding the mobile device about 0.5 to about 3.0 inches from an object to be disinfected.

Abstract: An illumination device having a plurality of light emitting diodes is provided. The light emitting diode may include a plurality of semiconductor layers at least one of which has a light emitting surface which may include a rough surface pattern having a pre-determined pattern. The pre-determined pattern may include one or more impurity regions with each region having a recess for guiding current across the light emitting surface and maximizing the emission of light (i.e. light intensity) of the illumination device. Each recess may include a lower internal portion having a bottom contact point located on a bottom surface and an upper internal portion integrally connected to the lower internal portion by a plurality of center contact points. The gaps created between the center and bottom contact points in adjacent recesses may act as spark gaps allowing for the current to flow through the entire light emitting surface.

The light emitting diode may include a plurality of semiconductor layers at least one of which has a light emitting surface which may include a rough surface pattern having a pre-determined pattern. The pre-determined pattern may include one or more impurity regions with each region having a plurality of peaks and valleys for directing the flow of current and causing an increase in the emission of light to reflect outwards from the light emitting surface while decreasing light reflected into the light emitting surface and as a result reducing the dissipation of heat. The plurality of impurity regions may be arranged such that a checkered pattern or configuration is formed by alternating the direction of the peaks and valleys in each region.

The illumination device may include an alternate current to direct current converter, a current regulator for receiving an output of the alternate current to direct current converter and a light source, containing the one or more of light emitting diodes, for receiving the regulated current from the current regulator. The regulated current may be applied to the one or more light emitting diodes causing the light emitting diodes to illuminate. The one or more light emitting diodes may be connected in series and each light emitting diode may include a light emitting surface having rough surface pattern for maximizing the light intensity of the light emitting diodes while minimizing the heat dissipating from the light emitting diodes.
