摘要:
A vented wound dressing barrier includes one or more membrane layers with a plurality of vents. The vents are cut along a perimeter of the vents through the one or more membrane layers. Each vent having a connection portion uncut relative to the one or more membrane layers thereby forming a hinge configured to allow the vents to open for drainage when exposed to fluid underlying the vented wound dressing barrier. The plurality of vents is each cut along the perimeter without removal of any of the membrane layer. The one or more membrane layers with the plurality of vents has a surface for covering a wound, the surface area in the absence of a fluid pressing on the vents having no openings or voids which reduce the surface area of a vented wound dressing barrier area covering a wound.

A therapeutic device for promoting the healing of a wound in a mammal is disclosed. An exemplary device comprises a permeable structure having a plurality of depressions formed in a surface thereof. In use, the surface having the depressions is disposed adjacent a surface of the wound. A method of manufacturing a therapeutic device for promoting the healing of a wound in a mammal comprising the steps of providing a permeable substrate, and forming a plurality of depressions into a surface of the permeable substrate to provide the therapeutic device. A method of treating a wound comprises: providing a permeable structure comprising a plurality of randomly disposed fibers and having i) a plurality of wound surface contact elements disposed between end portions of the structure, and ii) a plurality of voids defined by the contact elements; and applying the permeable structure to at least one surface of the wound.
摘要:
A hemostatic pad comprising a bioabsorbable scaffolding material; a lyophilized thrombin powder, a lyophilized fibrinogen powder, and a meltable binder powder, with all powders disposed on the bioabsorbable scaffolding material. A meltable binder such as PEG bonds the lyophilized thrombin powder and the lyophilized fibrinogen powder to the bioabsorbable scaffolding material for improved friability, wettability and performance in a use, such as for hemostatic treatment or sealing at a wound site.
摘要:
A combined compression and absorption dressing/bandage, which includes a short stretch compression bandage and at least one absorptive wound dressing comprising at least one absorbent layer of a non-woven fabric of any one or more of cotton, viscose and polyester fibres, the absorbent layer having an operative inner face and an operative outer face, the at least one wound dressing being bonded to the short stretch compression bandage with its inner face towards the bandage and the outer face facing away from the bandage.
摘要:
A tunnel dressing for use in treating a tunneling wound using negative pressure wound therapy. The tunnel dressing includes an elongate permeable member having a closed distal end for entering the wound and an open proximal end into which an applicator is removably disposed for guiding the dressing into the wound. The tunnel dressing has a support structure adapted to transport wound exudates away from the wound and to resist compression under suction. The tunnel dressing also has a wound contact surface adapted to minimize tissue entanglement to facilitate removal. The support structure and wound contact surface may be formed from the same material or from two adjacent layers of different material.

摘要:
A multi-layered wound dressing includes a moisture-retaining portion for enhancing the healing of a wound. The wound dressing includes an intermediate layer that has both water soluble and water insoluble fibers. An apparatus that includes a cutting tool and a reservoir of liquid to pre-moisten a portion of the dressing may be used to manufacture the dressings.
摘要:
An absorbent article, such as a wound pad, comprising a body of compressed thermoplastic or thermo-set open-celled foam is described, wherein the body has a pattern of ultrasonically made depressions in two opposite sides thereof, the depressions in the opposite sides being coaxial to each other and separated from each other by a common bottom portion which is compressed to a higher extent than the remaining parts of said body. A method for manufacturing such a body is also described.
