A chemically modified cellulose/alginate co-spun (seacell) fiber, a wound dressing made therefrom and a preparation method thereof. The seacell fiber is subject to a chemical modification through which a hydrophilic carboxymethyl group is introduced into the cellulose structure making the chemically modified seacell fiber more absorbent. The modified cellulose has a degree of substitution of 0.05-0.5; the seacell fiber has a linear density of 0.5-5 dtex and a fiber length of 5-180 mm. The seacell fiber has hygroscopic and gel-forming properties, while retaining its active ingredient of algae particles.

Wound dressings and wound inserts comprising a porous film layer and at least a channel, wound inserts of forming wound inserts comprising a porous film layer and at least a channel, and wound-treatment wound inserts.

A wound care device for delivering topical oxygen therapy and negative pressure wound therapy for treatment of a wound. The wound care device may include an oxygen supply membrane electrode device (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 negative pressure wound therapy to a wound. The wound care device may be operated to provide simultaneous topical oxygen therapy and negative pressure wound therapy, continuous oxygen therapy with intermittent negative pressure wound therapy, and alternating oxygen therapy and negative pressure wound therapy.

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.

A treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.

A combination therapy pad that includes a first layer and a second layer operatively coupled to the first layer. A fiber-optic array is disposed between the first layer and the second layer. A third layer is operatively coupled to the first layer. The third layer includes a vacuum tube in fluid communication with a vacuum source and a therapeutic fluid tube in fluid communication with a therapeutic fluid source. The third layer provides at least one of vacuum therapy and therapeutic fluid treatment to a wound area.

An apparatus and system for fluidly connecting a reduced-pressure source to a dressing and a method for manufacturing and using the same include a base having an aperture and a wall having a peripheral portion coupled to the base. The wall may form a cavity in fluid communication with the aperture. The apparatus also may include a conduit port fluidly coupled to the cavity and adapted to receive a conduit. The base may be adapted to couple to the dressing, and the wall may be adapted to collapse from a first position to a second position in response to a supply of reduced pressure from the reduced-pressure source.

Wound dressings and wound inserts including a porous film layer and at least a channel, forming wound inserts including a porous film layer and at least a channel, and wound-treatment wound inserts.

Tapes and methods including an unbacked construction of at least one liquid layer adhesive that has been at least one of dried and cured. Occlusive tissue dressings, tapes and methods including an elastomeric drape and, for backed drapes and some unbacked drapes, 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 of an elastomeric drape to create a similar air-tight seal around the tube, if not occlusively sealed during its manufacture. Featured are unbacked tapes, a drape with liquid sealant component, a liquid layered drape with liquid sealant component, and a liquid layered drape.

According to an illustrative embodiment a method to promote healing of a wound is provided comprising contacting the wound with a biologically active composition comprising a lipoic acid derivative and gelatin. In another embodiment a wound dressing is provided comprising a scaffold coated with a biologically active composition comprising a lipoic acid derivative. In a further embodiment, a system is provided for treating a tissue site of a patient, the system comprising a reduced-pressure source to supply reduced pressure, a manifold to distribute reduced pressure to a tissue site and a scaffold coated with a biologically active composition comprising a lipoic acid derivative. Methods for producing such a system and scaffold are also disclosed.
