  • Apparatus for aspirating, irrigating and cleansing wounds
    Patent number: 8398614
    Abstract: An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

  • AUXILIARY POWERED NEGATIVE PRESSURE WOUND THERAPY APPARATUSES AND METHODS
    Publication number: 20130018338
    Abstract: A negative pressure wound therapy apparatus that can include a wound dressing, a fluid collection device, a vacuum pump comprising a pump motor, and tubing can be powered by auxiliary power sources such as high efficiency batteries, photovoltaic panels or cells, fuel cells, combustion generators, human powered generators, or other mechanical, electrical, or chemical power sources such as hand operated dynamos or wound springs, or any combination of the foregoing. Additionally, the apparatus can include a high efficiency pressure controller for controlling the output of the vacuum pump.

  • Apparatus for cleansing wounds with means for supply of thermal energy to the therapy fluid
    Patent number: 8348910
    Abstract: An apparatus (1) for cleansing wounds (5) in which irrigant fluid from a reservoir connected to a conformable wound dressing (2) and wound exudate from the dressing are moved by a device (18) (which may be a single pump or two pumps) for moving fluid through a flow path (6, 7, 9, 10) which passes through the dressing with a means for providing simultaneous aspiration and irrigation of the wound, and means for supplying thermal energy to the fluid in the wound. The former provides a desired balance of fluid at a controlled nominal flow rate that removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing over the wound bed. The latter maintains a temperature at the wound bed under the wound dressing at a level that promotes wound healing.

  • WOUND CLEANSING APPARATUS WITH SCAFFOLD
    Publication number: 20120259297
    Abstract: An apparatus for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid containing a physiologically active material from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. A biodegradable scaffold underlies the dressing on the wound bed to promote tissue growth. The cleansing means (which may be a single-phase, e.g. micro-filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing, an assembly comprising the dressing and scaffold, and a method of treatment using the apparatus.

  • Apparatus and method for filter cleaning by ultrasound, backwashing and filter movement during the filtration of biological samples
    Patent number: 8273253
    Abstract: The present application is directed to the separation of—a solid fraction from a fluid sample particularly a therapeutic cellular fraction from a biological sample such as a bone marrow sample by a porous filter (2) which separates a filtration unit (1) into an upper pre-filtration chamber (3) into which a fluid sample (4) requiring cell separation is introduced and a lower post-filtration chamber (5) into which a fluid (6) capable of transmitting an acoustic standing wave is introduced. An acoustic element (8) is coupled to a substrate (7) which is located within and at the bottom of the lower chamber (5) and which resonates in response to the acoustic generating element (8) and generates a standing wave through the two fluid phases and the filter to agitate the sample (4). Simultaneously, a cyclic process of vacuum draw (9). causes movement of the sample (4) downwards through the filter (2).

  • SYSTEMS AND METHODS FOR CONTROLLING OPERATION OF A REDUCED PRESSURE THERAPY SYSTEM
    Publication number: 20120165764
    Abstract: Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor the duty cycle of a source of negative pressure and, based on the monitored duty cycle, determine whether a leak is present. The controller can be configured to provide an indication that a leak is present. For example, the controller can be configured to suspend and/or pause the delivery of therapy, and to restart the delivery of therapy due to a timeout, request from a user, etc. In addition, the controller can be configured to pause and/or restart the delivery of therapy upon a request from the user, such as in response to the user operating a switch.
