  • Publication number: 20130087460
    Abstract: A method for treating a surface of a metal implant includes a polishing step, a grafting step. The polishing step includes polishing a surface of a metal implant to remove an uneven, natural oxide layer on the surface of the metal implant and to generate an even oxide layer on the surface of the metal implant. The grafting step includes grafting an anti-adhesion macromolecule on an outer face of the even oxide layer. A covalent bond between the anti-adhesion macromolecule and oxygen atoms on the outer face of the even oxide layer is formed, thus that a macromolecular anti-adhesion layer on the outer face of the even oxide layer can be created. The surface modifying step includes changing a property of the surface of the metal implant with the macromolecular anti-adhesion layer by high temperature and high pressure, providing the metal implant with high hydrophilicity.

  • Publication number: 20120076847
    Abstract: A medical instrument and a manufacturing method thereof are provided. The medical instrument includes a biomedical metal layer and a polymer film. The polymer film is a biodegradable polymer material. The manufacturing method includes the following steps: providing the biomedical metal layer, immersing the biomedical metal layer in a polymer solution, performing a baking process on the biomedical metal layer coated with a polymer film, forming the biomedical metal layer coated with the polymer film, taking out the biomedical metal layer coated with the polymer film to fabricate the medical instrument. The biodegradable polymer film and the biomedical metal layer are combined into the medical instrument, so that a physician performs a surgery more easily. In addition, decomposition time of the polymer film can be preset, so as to achieve efficacy of blocking soft tissue cells having a higher growth rate.

  • Patent number: 7543603
    Abstract: A tube defines a cavity. Normally-open fitting (2) and normally-closed fitting (3) are respectively fitted into the tube to form ports (34),(35) having seats (40),(13). A body secured to fitting (3) defines a chamber (26) to which port (35) leads. Body (4) defines holes (27),(30) leading into chamber (26). A solenoid assembly (6) is slidable within chamber (26), includes a coil, segregates chamber (26) to chambers (7),(29) which communicate respectively with holes (27),(30) and defines a chamber (16), a seat (18), a seal (14) and an orifice (33) leading between seat (18) and seat (13). A rod-piston assembly includes a rod (37) attached to: assembly (6), sealably passing through body (4) into cavity and preventing gas communication between cavity and chamber (7); and a piston with a seal (39). A magnetic rod (15) slides within chamber (16). Spring (17) urges rod (15) towards seat (18) to seal orifice (33). Spring (12) urges assembly (6) towards seat (13) to seal port (35).

  • Patent number: 7334770
    Abstract: An improved pilot-operated, “instant-on”, solenoid isolation valve discloses a new fluid passage route to save cost of drilling a longitudinal hole within the primary piston. Also, a new feature of primary piston assembly with a movable seal piston having a specific circumferential surface matching to valve body chamber to restrict fluid from front side into back side of the primary piston to produce pressure difference to induce instant valve open when solenoid is energized initially. It also introduces a channel hole in the flange of the sleeve assembly as a communication channel of supply of gas into the chambers of the back side of primary piston assembly. The diameter of the channel hole is not critical to determine in this new invent. As long as the size of the hole is smaller than that of the bleed hole, it can maintain pressure difference between the front side and back side of primary piston during valve opening operation.

  • Publication number: 20070175529
    Abstract: A new three-way, two-position in-tube solenoid gas valve assembly comprises a modified in-tube solenoid gas valve and a pair of gas release valves is designed to control pneumatic systems. The modified in-tube solenoid gas valve is a modification based on the previous invention by Wang et al., U.S. Ser. No. 10/924,789. The new modifications are first adding a rod-piston assembly onto the solenoid assembly, a new inlet was added to the valve tube and two outlet fittings were also added. With these modifications, the systems can now work with two directions of gas flows, which is important to control pneumatic systems. To be able to control pneumatic systems properly, two gas release valves are included as part of the assembly. The goal of these two gas release valves is to be able to release gas from pneumatic quickly and completely. These gas release valves are operated based on two compression springs and through gas inputs into the valves.

  • Publication number: 20060043323
    Abstract: A newly designed solenoid gas valve which including a solenoid assembly and inlet & outlet fittings is installed inside a tube. The adoption of in-line inlet and outlet configuration simplifies the procedures required for connecting the pipes and the gas flow is controlled by opening and closing the valve in a piping system. The opening and closing of the valve is operated by the pressure difference with an aid of the magnetic field. A compression spring is attached to the support cylindrical body and held against the inlet end fitting while a moving solenoid assembly is located inside the support cylindrical body. The moving solenoid assembly that consists of a stop, a flange, a sleeve and an electrical coil, is held by a second compression spring that is attached to the inside of the support cylindrical body. A small moving magnetic rod, slides inside the sleeve of the solenoid assembly.
