摘要： Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

摘要： 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.

摘要： To reduce the suffering of the patient and enable easier removal of excess fluid such as pleural effusion fluid from the chest space, the disclosure provides a catheter for chest drainage intended for removal of excess fluid from a chest space of a living body and to be placed in the living body in such a manner as to extend from an inside of the chest space to an outside of the living body. The catheter includes a passage member formed of a flexible sheet and having a passage through which the excess fluid is to be drained, and an indwelling member formed of an elastic body and provided at a proximal end of the passage member. The indwelling member has an inlet that allows the excess fluid to flow through. The indwelling member includes a retaining portion spreading in a flange shape and being retainable at a chest wall.

摘要： A mechanical wound therapy (MWT) system includes a connection for a vacuum source, which is routed through an airtight covering to a porous material positioned over the wound. The porous material may be a tubing network interspaced by a netting material constructed of biologically inert or bioabsorbable material. Alternatively, the porous material may be a layered unified dressing in which layers of mesh, netting or thin perforated film are separated and fixedly attached to functional elements of the dressing (e.g., irrigation tubing) or spacers. The vacuum and irrigation systems may be completely separated. An airtight sealing layer or foldable adhesive sealing layer may seal the dressing and facilitate sealing the dressing to the wound margins. Additional modular devices such as a wound approximating system, positive pressure bladders and adjuvant therapy modules as well as enhanced monitoring technology can be added to synergistically increase the capabilities of each dressing.

摘要： In one example embodiment, a system for treating a tissue site is disclosed comprising a dressing adapted to contact the tissue site and provide a fluid seal between a therapeutic environment and a local external environment, and a solution source fluidly coupled to the dressing and adapted to deliver an antimicrobial solution comprising a peroxy α-keto carboxylic acid, such as peroxy pyruvic acid, to the tissue interface. The system may further comprise a negative-pressure source fluidly coupled to the dressing and adapted to provide negative pressure to the therapeutic environment after delivery of the antimicrobial fluid to the therapeutic environment. In another example embodiment, a method for treating a tissue site is disclosed comprising positioning a tissue interface to contact the tissue site, covering the tissue interface and the tissue site with a drape to provide a fluid seal between the therapeutic environment and the local external environment, and delivering an antimicrobial solution comprising peroxy α-keto carboxylic acid to the therapeutic environment before providing negative pressure to the therapeutic environment.

摘要： A wound therapy device includes a wound dressing and a humidifier configured to deliver humid air to a wound site to which the wound dressing is applied. The humidifier may be a remote structure that is fluidly connected to the wound dressing applied about a patient's skin at a wound site. Alternatively, the humidified may be integrated with the wound dressing to define an integral, portable therapy device that may be worn by the patient. The wound therapy device may be a standalone wound treatment device, or may be used in conjunction with other wound treatment devices, such as, e.g., negative pressure wound therapy devices.

摘要： Systems, devices and methods for removing a blood clot (10) from a blood vessel (12). Various uses of suction pressure and positive pressure, proximal and/or distal to the blood clot (10) assist with clot dislodgement and removal. The pressure(s) may be constant and/or cycled/pulsed to assist with clot dislodgement and/or removal. Various further devices assist with separating the clot (10) from the vessel (12).

摘要： A method for treatment of a brain and/or spinal cord includes inserting a flexible catheter into a cerebrospinal fluid space, the flexible catheter including two lumens adapted to allow a fluid to circulate therein in a closed loop within the flexible catheter and the flexible catheter being adapted to be connected to a device for cooling and circulating the fluid. The cerebrospinal fluid in the cerebrospinal fluid space is cooled with the flexible catheter to enable selective central nervous system cooling. The functional status of the brain and/or spinal cord is monitored, and the treatment of the brain and/or spinal cord is modified to adjust for any change in the functional status of the brain and/or spinal cord.
