A head and neck covering is cut from a flat sheet of foam material to form a body portion of the head and neck covering. The foam material has a first surface cut to form an eye region, mouth region and neck region. The foam material has a second surface opposite the first surface which is continuous other than an opening for intubation. The foam material is compliant so that the body portion conforms to contours of the head and neck of the anesthetized patient. A closure mechanism is attached to the body portion for securing the head and neck covering around the anesthetized patient. The foam material reduces a potential for trauma to the head and neck of the anesthetized patient. A plurality of channels is formed in the foam material. Warm fluid is circulated through the channels to reduce heat loss for the patient.

The invention provides a solid foam wound dressing useful for hemorrhage control and wound repair, as well as methods for making such a wound dressing.

A method of making an absorbent insert for absorbing fluid in a root canal. Forming a body in a pre-compressed state prior to use, having a matrix of absorbent material. The matrix of absorbent material swells upon absorbing fluid after the body in the pre-compressed state has been inserted into the root canal. In the forming process, a sheet of absorbent material is compressed to form a compressed sheet, which is cut and shaped to form an insert. Cutting and shaping is by using complementary split mold halves which together define a cavity corresponding to the body of the insert and stamping the compressed sheet with the split mold halves to form the body of the insert.

A structure for use in repairing a defect in a substrate is provided. The structure includes a first layer and a second layer coupled to the first layer using a first coupling process. The first layer is formed by a plurality of polymeric fibers, and the second layer has a plurality of densities formed by a plurality of polymeric fibers. The first and second layers of the structure are configured to separate after at least one of a predetermined time and an environmental condition.

A method of manufacturing a reduced-pressure abdominal treatment system for treating an open abdominal cavity is provided. In some embodiments, the reduced-pressure abdominal treatment system has an open-cavity treatment device for providing reduced-pressure treatment to an abdominal cavity; a deep-tissue closure device for applying a closing force on a deep-tissue wound; and a surface-wound closure subsystem for providing a closing force on a surface wound. The method of manufacturing may also include providing a reduced-pressure supply subsystem. A method of treatment using a reduced-pressure abdominal treatment system is also disclosed.

A non-woven gauze product and a method and system for manufacturing same. The spunlace device includes a second spunlace machine having a shaping layer on the surface, the shaping layer is provided with pointed projections having tapered tops disposed in a matrix arrangement, each pointed projection has a bottom of rectangular cross-section, the bottom size of each pointed projection is larger than the bottom distance between two adjacent pointed projections. A non-woven cloth having rectangular holes in an array layout is formed by water jetting the fiber-web at the second spunlace machine. The rectangular holes in an array layout are presented in a flat structure having warp and weft, and the dimension of each rectangular hole is larger than the line width of warp and weft. The features of such non-woven cloth are similar to those of gauze, so the non-woven cloth can be a substitute for the current gauze.

A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.

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.

A wound packing material is provided, suitable for use in negative pressure wound therapy, including a body of a porous material, the body including frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body. Methods of manufacturing the wound packing material, and methods of its use are also provided.

A wound dressing includes a patient interface layer, a wicking layer, an absorbent layer, and a cover layer. The patient interface layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The wicking layer, absorbent layer, and cover layer all also have a first side and a second side. A perimeter of the first side of the wicking layer is adhered to the second side of the cover layer, forming an adhesive border surrounding the wicking layer and the absorbent layer, and the wicking layer is configured to peripherally wick perspiration from underneath the adhesive border towards the center of the wicking layer and upwards towards the absorbent layer.
