    摘要： A system and method for the temporary closure of a wound, especially an abdominal wound, to facilitate re-entry, final closure, and long term healing of the wound. An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a site healing promoting manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material (36) enclosed by sheets of elastomeric material (38) punctuated by a number of appropriately placed holes (34). Multiple layers of porous foam may also be used. A suction tube connector (16) is provided on an upper surface of a layer of foam (12) for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope, and through the foam. If multiple foam layers are employed, the lower layer(s) of foam are of a finer porosity while the upper layer of foam is coarse. An adhesive elastomeric sheet (14) covers the entire wound dressing and seals the edges to the skin surrounding the wound. An appropriate vacuum device is attached to the suction tube connector.

    摘要： A mobile safety fall arrest cart is provided. The mobile safety fall arrest cart is configured to move along an edge of an elevated surface as a worker works along the edge. The worker is connected to the cart with a safety line. If the worker falls from the elevated surface, the weight of the worker causes a spike assembly to move from a stowed configuration to a deployed configuration. In the deployed configuration, a spike member engages the elevated surface so as to assist in arresting the worker's fall.

    摘要： Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a desirable combination of physical and chemical properties. Crosslinked bulk materials are heated to a compression deformable temperature, and pressure is applied to change a transverse dimension of the material. After cooling and stress relieving, a treated bulk material is obtained that has enhanced tensile strength in the axial direction orthogonal to the dimension change. In preferred embodiments, medical implant bearing materials are machined from the treated bulk material with the in vivo load bearing axis substantially parallel or coincident with the axial direction of the treated bulk material.

    摘要： An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The method comprises providing a flexible film having a plurality of holes therein and placing the flexible film in the wound. The flexible film has a first, patient-facing side and a second side. The method includes placing a porous pad on top of the second side of the flexible film. The flexible film and porous pad are sealed within the wound with a drape that is positioned in contact with an area of skin surrounding the wound. A negative pressure is provided to the porous pad for drawing a flow of exuded fluids from the wound.
