A wound dressing includes a substrate, an insulating layer, at least one ion sustainable-released body, and at least one electrode. The insulating layer is disposed on the substrate, with the at least one ion sustainable-released body being uniformly disposed at the insulating layer. The ion sustainable-released body includes ions. The electrode is disposed on the insulating layer, and the electrode and the ions are functioned as an electron donor and an electron acceptor respectively.

A dressing for negative pressure wound therapy includes an absorbent layer comprising a gelling absorbent material for absorbing exudate, a peripheral adhesive skin contact layer comprising a hydrocolloid adhesive and defining a window through which the absorbent layer is able to contact a wound, and a cover layer that is water impermeable and air permeable. The cover layer defines an aperture to be used with a pump assembly to provide negative pressure to a wound site.

A wound healing device and method that greatly reduces the risk of infection of an incision or wound by removing fluid from the subcutaneous skin layers. The wound healing device includes a first portion that is positioned external of, and on top of, the wound. At least one strip, cord, finger, member is in fluid communication at one end with the first portion while the second free end of the at least one strip, cord, finger, member is pushed down into the wound, in between the sutures or staples of a closed incision. Both the first portion and the at least one strip comprise fluid absorbable material for absorbing the wound fluid. The device remains in place for approximately 1-3 days after which it is removed. Upon removal, natural temporary “type of fistulae” are formed in the subcutaneous skin layers to continue draining wound fluids upward for another 1-2 days.

Provided are buffered adhesive compositions comprising a high molecular weight non-neutralized polymeric acid and a high molecular weight partially neutralized polymeric acid and products such as wound dressings and ostomy skin barriers incorporating the compositions.

Dressings for treating a tissue site with instillation therapy are disclosed, which may include a dressing having a first layer comprising a polymer film having a plurality of fluid restrictions through the polymer film and a second layer comprising a polymer having a plurality of apertures. The second layer is adjacent to the first layer. The dressing may include an adhesive layer on at least a portion of the first layer. Further, the dressing may include a third layer on the adhesive layer, the third layer being at least partially removable from the adhesive layer so as to expose a portion of the adhesive.

An assembly including a suctioning device suitable for being placed on an incision and/or a wound of a patient to disinfect and/or dry the incision or wound, the device including a drape. The drape includes an outer layer with an upper face and a lower face, the upper face being impermeable, an inner layer, made of non-woven sterile material, including an upper face and a lower face, the lower face to come into contact with the wound and/or the incision. The drape is wound around a limb or around the body of the patient. The assembly also includes a suctioning zone having cavities, a discharge tube connected to the suctioning zone, and a suctioning member is a system for recovering portable or mobile autologous blood.

A wound dressing comprising a breathable film, a fluid-absorption layer and a fluid-wicking layer, use of the wound dressing for treating or preventing wounds and/or for securement of a device that has been at least partially inserted in the skin, and methods of making said wound dressings.

A therapeutic compress assembly, system, and method for treating an area of a user is disclosed herein. The therapeutic compress assembly includes an elastic fabric compress and an absorbent pad. The elastic fabric compress is stretchable in a length direction and a width direction. The absorbent pad is coupled to a first side of the elastic fabric compress. The absorbent pad may be impregnated with a medication or an oil. In use, the therapeutic compress assembly is applied to the area of the user.

A dermal patch includes: an open-cell foam layer; and an adhesive layer arranged thereon and intended for contact with skin. At least a side of the foam layer facing the adhesive layer has macropores whose cavities are spanned at least partially by a barrier layer formed from the foam layer.

Embodiments of apparatuses, systems, methods for monitoring wound pH are disclosed. In some embodiments, a wound dressing includes one or more optical sensors configured to measure a change in color of a pH-sensitive adhesive that changes color in response to changes in wound exudate pH. In some embodiments, the wound dressing may further comprise hydrophilic channels that direct wound exudate to a pH-sensitive material over the optical sensors. Such dressings may also be used in combination with a negative pressure wound therapy system.
