  • Publication number: 20230329918
    Abstract: A pressure-reducing dressing is adapted for securing medical equipment to the skin of a human body, and includes a skin contact pad adapted for locating the medical equipment, a water barrier laminate positioned on the skin contact pad, and a release sheet. The water barrier laminate includes a body layer and an adhesive layer formed on a side surface of the body layer that faces the skin contact pad and adhered to the skin. The body layer has a positioning portion and two divisional portions extending from the positioning portion and spaced apart from each other by a separating gap. The release sheet is attached to the adhesive layer of the water barrier laminate.

  • Publication number: 20230293353
    Abstract: A wound patch includes a main body made of a non-woven fabric and having opposite first and second surfaces, an adhesive layer disposed on one of the first and second surfaces of the main body, a waterproof layer disposed on the other one of the first and second surfaces of the main body, and a plurality of pore-forming sections penetrating through the main body, the adhesive layer, and the waterproof layer. The adhesive layer is attached to a wound when the adhesive layer and the main body are stretched by an external force.

  • Patent number: 11064764
    Abstract: A hidden drainage system for shoes, configured on the outsole of a shoe, in which the two sides of the outsole are provided with a plurality of curved sections that are curved inward; the top of the outsole is provided with a plurality of transverse drainage troughs and several longitudinal drainage troughs; each of the transverse drainage troughs extends along the direction of the width of the outsole, and both ends are communicated with each of the curved sections, so that the two ends of each of the transverse drainage troughs will not be exposed on the side face of the outsole; the longitudinal drainage troughs extend along the length of the outsole and are communicated with each of the transverse drainage troughs; thus, water entering the shoe will flow into each of the transverse and longitudinal drainage troughs, and be discharged from each of the transverse drainage troughs.

  • Patent number: 7409783
    Abstract: This invention relates to an improved spike installed in a sole of a shoe and consists of a receptacle having a base and several connecting seats integrated around the edge of the base in one piece flexibly moving in proportion to the base. Several spikes are installed unto individual connecting seats extruding the sole. Accordingly, each connecting seat and partial spikes are wrapped up by the flexible sole. When spikes receive an external force causing connecting seats to deviate slightly and simultaneously, the elasticity of the sole material and elastic recovery of each connecting seat are used ingeniously to create proper grip.

  • Patent number: 5765331
    Abstract: An improved light weight wall structure for buildings is disclosed. It contains: (a) a skeletal frame having a plurality of posts for quick assembly; (b) a plurality of gusset sub-panels and base board sub-panels disposed in overlapping and alternate relationship fastened to the skeletal frame; (c) connection means provided in each junction between adjacent sub-panels for securely adjoining the sub-panels together; (d) a slurry retention device disposed on at least one major surface of a selected number of sub-panels; (e) a wall facing layer applied to the sub-panels in the form of a setable slurry, so as to increase the strength of the wall structure; and (f) a protection plate mounted on a portion of the wall structure that is most likely to be damaged.

  • Patent number: 5595035
    Abstract: A built-up post for use in a building is disclosed. It includes: (a) an upper post resembling a long column, the upper post having a first end to be fixedly connected to a steel girder or a ceiling of a building, and a second end having a longitudinal hole, the longitudinal hole having an inner wall with an internal thread; (b) a lower post resembling a long column, one end to be fixedly connected to a steel girder or a floor of a building, the other end having a longitudinal hole, the inner wall of the longitudinal hole having an internal thread; and (c) an intermediate post resembling a long column, each end thereof having a long thread for screwing into the longitudinal holes of the upper and lower posts. The upper post, intermediate post and lower post are joined in alignment with each other, with the long threads of the intermediate post being screwed into the longitudinal holes of the upper and lower posts, respectively.

  • Patent number: 5177918
    Abstract: A shock-absorption wall structure comprising a framework of elastic beams having a light steel frame covered with a certain number of base plates is disclosed. The base plates have at least two or more rows of parallel sheets in the upper/lower sides or left/right sides and a plurality of inclined sheets and/or rolling sheets to make paving slurry even and quick, and enable the slurry to evince a strong adhesive force. Each elastic beam includes a pair of truss bodies interconnected by number of long bolts and springs with each long bolt penetrating through a respective pair of truss bodies. The springs are accommodated within the truss body and then a cover plate is attached on one side of the elastic beam. By this arrangement, the internal stress of the wall arising from an earthquake or working vibration can be absorbed by each spring to prevent the wall from cracking or collapsing.
