20100262092 | DRESSING - A dressing for the application of topical negative and/or positive pressure therapy to a wound is described together with a method for creating the dressing, the dressing comprising in use: an optional layer of a pressure resistant porous material adjacent a surface of a wound to be treated; a first layer of a flexible wound covering and sealing material on top of the optional pressure resistant porous material adapted, in use, to surround the wound and seal against sound tissue to form, in use, a first sealed cavity with the wound; a first conduit having a first end adapted to communicate with an interface between said optional layer of porous material and said first layer of flexible wound covering and sealing material and a second end adapted to communicate with vacuum means to establish a negative pressure, in use, between said first covering and sealing material layer and a wound surface; a resiliently compressible wound packing material on top of said first layer of covering and sealing material; a second conduit having a first end adjacent said resiliently compressible wound packing material and a second end adapted to communicate with positive or negative pressure generating means; and a second layer of flexible covering and sealing material over said resiliently compressible wound packing material to form, in use, a second sealed cavity above said first sealed cavity and said wound. | 10-14-2010 |
20110028917 | WOUND MANAGEMENT - A method and apparatus are disclosed for delivering at least one agent to a wound site. The method includes the steps of providing a delivery tube having an outlet at a wound site, covering the wound site with a drape and introducing agent at an agent inlet port of the delivery tube. The agent passes along the delivery tube through the drape to the wound site. The agent can be a wide variety or mixture of fluids such as but not limited to pain relief medicament, anti-biotics, saline solution and/or hydrating fluid. | 02-03-2011 |
20110028921 | PORTABLE WOUND THERAPY APPARATUS AND METHOD - Methods and apparatuses are disclosed for providing topical negative pressure to a wound. One such apparatus comprises a waste canister for collecting and holding wound exudate and at least one pump arranged to urge wound exudate along a flow path from the wound to the waste canister. The pump can be further configured to deliver a single factory set pressure. Accordingly, the pressure delivered to the wound would be determined by the pressure set for the pump along with the parameters associated with the flow path, such as whether a leak or a blockage occurs. | 02-03-2011 |
20110171543 | POWER GENERATION - A method and apparatus are disclosed for generating electrical power during negative pressure therapy. The apparatus includes a fuel cell, comprising an anode element and a cathode element, arranged to collect biological fluid from a wound site to which a negative pressure is applied and electro-oxidize a component of the biological fluid at the anode element and/or electro-reduce a component of the biological fluid at the cathode element. | 07-14-2011 |
20110172612 | Negative Pressure Wound Therapy Device - Apparatus for the application of topical negative pressure, or vacuum, therapy to a wound site. | 07-14-2011 |
20110251567 | APPARATUS FOR ASPIRATING, IRRIGATING AND CLEANSING WOUNDS - 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. | 10-13-2011 |
20120143156 | FLUID COMMUNICATION PATH - An apparatus and method are disclosed for providing a fluid communication path to a wound site through a drape. The apparatus comprises a body portion having a lower surface and an upper surface, at least one connection port, at least one suction port and at least one fluid communication passageway between the connection port and the suction port. A connector at an end of at least one tubular conduit is locatable through the drape into an orifice in the connection port to thereby provide a fluid communication path through the drape between the tubular conduit and the wound site. | 06-07-2012 |
20130018338 | AUXILIARY POWERED NEGATIVE PRESSURE WOUND THERAPY APPARATUSES AND METHODS - 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. In some embodiments, the pressure controller can control the pump without using a processor, and can have other features such as an intermittent delay function and an anti-stall mechanism to reduce the energy consumption of the apparatus. | 01-17-2013 |
20130144233 | SUSTAINED VARIABLE NEGATIVE PRESSURE WOUND TREATMENT AND METHOD OF CONTROLLING SAME - Disclosed herein are systems and methods for providing reduced or negative pressure, and more particularly cyclical reduced pressure, to treat a wound. The system can include a wound dressing, a fluid collection container, a suction source, filters, and conduits. In addition, the system can include a control device and sensors. The sensors may be configured to monitor certain physiological conditions of a patient such as temperature, pressure, blood flow, blood oxygen saturation, pulse, cardiac cycle, and the like. Application of cyclical reduced pressure between two or more values below atmospheric pressure may be synchronized with the physiological conditions monitored by the sensors. Certain embodiments of the system utilize an air reservoir and one or more valves and pressure sensors or gauges to allow for rapid cycling of the level of reduced pressure within the wound dressing between two or more reduced pressure values. | 06-06-2013 |
