Adaptable wound drainage system
Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.
APPARATUSES AND METHODS FOR NEGATIVE PRESSURE WOUND THERAPY
Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, having an air leak channel separated from a suction channel.
MULTIPLE DRESSING NEGATIVE PRESSURE WOUND THERAPY SYSTEM
Embodiments described herein relate to apparatuses, systems, and methods for the treatment of wounds, for example using multiple wound dressings in combination with negative pressure wound therapy. A negative pressure would therapy apparatus can include a negative pressure source and a controller. The negative pressure source can include inlets configured to couple via fluid flow paths to wound dressings. The fluid flow paths can include pressure sensors configured to measure pressure in the fluid flow paths. The pressure sensors can include a first pressure sensor configured to measure pressure in the first fluid flow path and a second pressure sensor configured to measure pressure in the second fluid flow path. The controller can be configured to operate the negative pressure source and provide, based on measured pressure, indication of at least one operating condition associated with at least one of the fluid flow paths.
NEGATIVE PRESSURE TREATMENT INCLUDING MECHANICAL AND CHEMICAL PUMP
A negative pressure assembly includes a drape, a sealing element, a reactor, and a mechanical pump assembly. The drape covers a dressing site on a patient and seals against the skin upon application of a vacuum while maintaining a negative pressure underneath the drape. When applied to the skin, the sealing element cooperates with the drape to define an enclosed volume covered by the drape and surrounded by the sealing element. The reactor is located with respect to the drape and the sealing element to be in fluid communication with the enclosed volume when the drape is covering the dressing site and is configured to react with and consume a selected gas found in air. The mechanical pump assembly is connectable to the enclosed volume and has a pump chamber in fluid communication with the enclosed volume to draw air from the enclosed volume into the pump chamber.
Systems and methods for tissue healing
Systems, methods and devices are provided for use in a negative pressure wound therapy system for healing a wound in a patient. Various aspects may include an ester-based material adapted to be directly applied to the wound, such as a smooth muscle fistula, without substantially damaging tissue in the wound during dressing changes. The ester-based material may have an affinity for the wound bed surface and/or wound fluid. In addition various aspects may include a device adapted to close the wound, such as a smooth muscle fistula.
Mechanical wound therapy for sub-atmospheric wound care system
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.
FLUID BRIDGE FOR SIMULTANEOUS APPLICATION OF NEGATIVE PRESSURE TO MULTIPLE TISSUE SITES
Disclosed embodiments may relate to devices, systems, and methods for providing negative-pressure therapy simultaneously to a plurality of tissue sites using a single negative-pressure source. For example, a fluid bridge may comprise a plurality of distal ends, each configured to interact fluidly with a tissue site. In some embodiments, each distal end may have an aperture. The bridge may also comprise a port for entry of negative pressure into the enclosed space of the bridge. In some embodiments, each distal end may comprise a one-way valve. The enclosed space of the fluid pathway between the distal ends and the port may be supported in some embodiments, to prevent collapse due to negative pressure and/or compression.

Wound management assembly and negative pressure wound therapy system
The present disclosure relates to a wound management assembly. The wound management assembly comprises a housing and an exudate collector received in the housing. A gap is defined between the housing and the exudate collector to form a channel for fluid passage, wherein the fluid passes into and through the exudate collector and radially enters the channel.
