    Abstract: A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

    Abstract: Systems and devices for treating a tissue site may include an interface adapted to provide a reduced pressure to a dressing. The interface may include a positive-pressure channel for delivering a positive pressure from a positive-pressure port to a positive pressure outlet. The positive-pressure channel may include a constricted portion configured to provide a pressure drop. The interface may additionally include a reduced-pressure channel adapted to deliver reduced pressure to the dressing that substantially corresponds to the pressure drop. The reduced-pressure channel may be fluidly coupled between the positive pressure channel and a side of the interface body adapted to face the dressing. Other systems and devices are disclosed.

    Abstract: A disc pump includes a pump body having a cavity for containing a fluid. The disc pump also includes an actuator adapted to hold an electrostatic charge to cause an oscillatory motion at a drive frequency. The disc pump further includes a conductive plate positioned to face the actuator outside of the cavity and adapted to provide an electric field of reversible polarity, the conductive plate being electrically associated with the actuator to cause the actuator to oscillate at the drive frequency in response to reversing the polarity of the electric field. The disc pump further includes a valve disposed in at least one of a first aperture and a second aperture in the pump body. The oscillation of the actuator at the drive frequency causes fluid flow through the first aperture and the second aperture when in use.

    Abstract: A wound therapy system and method for clearing fluids from a conduit includes a wound dressing apparatus, a pneumatic pump, a valve, and a controller. The wound dressing apparatus is fluidly coupled to a wound, the pump, and the valve. The controller is configured to determine a volume of instillation fluid that has been delivered to the wound, to operate the pneumatic pump and the valve to apply a negative pressure to the wound dressing apparatus to purge a first portion of the instillation fluid, and to operate the pneumatic pump and the valve during a purge operation to deliver a volume of air through the wound dressing apparatus that is approximately equal to or greater than the volume of instillation fluid to purge a second portion of the instillation fluid from the wound dressing apparatus.

    Abstract: Provided herein is a system and method for mitigating premature light deactivation of light deactivated adhesive drapes. One aspect provides a system comprising a drape, an adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a photochromic layer that may transition between a blocking transmittance state and a non-blocking transmittance state to block or allow certain wavelengths of light to pass through. Some systems may use a combination of a photochromic layer and a filter layer to prevent the adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing one or more of a photochromic layer and a filter layer and applying light to the drape to deactivate the adhesive layer and promote easy, clean, and less painful removal of the drape.
