Foam wound inserts with high-density and low-density regions, methods for making wound inserts, wound-treatment methods, and wound-treatment systems.

A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply MEA, an oxygen consuming MEA, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.

An oxygen-generating wound dressing is provided. The oxygen-generating wound dressing comprises a housing and a wound contacting layer. The interior of the housing comprises a barrier member to divide the housing into a reactant receptacle and a wound contacting layer receptacle. The reactant receptacle of the housing further comprises a first reactant receptacle, a second reactant receptacle, a check valve disposed between the first reactant receptacle and the second reactant receptacle, a flow regulating device disposed on the second reactant receptacle and a gas deliver tube for fluidly communicating the first reactant receptacle and the wound contacting layer receptacle. The entrance speed of the second reactant into the first reactant receptacle can be controlled by the flow regulating device. The oxygen partial pressure can be maintained preferably and the wound healing can be improved by using the oxygen-generating wound dressing of the present invention.

Disclosed herein are targeted temperature management (“TTM”) systems, pads, and methods thereof for treating burn wounds. A method of a system for TTM can include a pad-connecting step, a pad-placing step, and a fluid-circulating step. The pad-connecting step can include connecting an inlet and an outlet of a pad to a hydraulic system of a control module. The pad can include a multilayered pad body having a conduit layer configured to convey a temperature-controlled fluid provided by the control module. The pad-placing step can include placing the pad on a wounded portion of a patient's body with a sterile, thermally conductive wound-healing layer of the pad body in contact with a burn wound of the wounded portion of the patient's body. The fluid-circulating step can include circulating the temperature-controlled fluid through the conduit layer to cool the wounded portion of the patient's body, thereby treating the wound to promote healing.

Devices and methods for delivering and filtering a gas to a wound site to enhance healing, reduce the potential for bacterial infections, lessen the need for antibiotics and to create a protective and therapeutic gas atmosphere along a treatment site. More particularly, the invention relates to a device arranged to deliver a gas to a treatment site, the device being connectable to a gas source, the device including (i) a first membrane comprising a flexible, microporous polymer body and (ii) a second membrane comprising a flexible nonporous polymer body. Outer edge portions of the second membrane are bonded to outer edge portions of the first membrane to form an interior chamber of the device, the interior chamber of the device confining introduced gas to the interior chamber such that the introduced gas flows out through the pores of the first membrane and is diffused along the treatment site.

A treatment system for applying negative pressure therapy and fluid instillation treatment to a tissue site, particularly an abdominal tissue site, is disclosed. In some embodiments, the treatment system may include a dressing member, a plurality of fluid removal pathways, a fluid instillation matrix, a drape, a negative-pressure source, and a fluid instillation source. Instillation fluid may be delivered from the fluid instillation source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.

Foam wound inserts with high-density and low-density regions, methods for making wound inserts, wound-treatment methods, and wound-treatment systems.

Wound dressings and wound inserts comprising substantially dry reactive agents, methods of forming wound inserts comprising dry reactive agents, and wound-treatment methods.

Occlusive tissue dressings and methods including an elastomeric drape and a liquid component, at least partially cross-linked at least after one of drying and curing, suitable for application at a dressing-to-skin interface in order to create a substantially air-tight seal. The same or a different liquid component may be applied by a user at a tube-to-dressing interface in order to create a similar air-tight seal around the tube, if not occlusively sealed during its manufacture.
