Patent number: 9764123Abstract: A needle-less connector includes a housing having a drug solution flow path, and an elastic valve body. An end surface of the housing on a side of a tip end opening of the drug solution flow path constitutes a protruding support surface whose center section protrudes and slopes in a direction of a foot, and the elastic valve body is superposed onto the protruding support surface in a state of close contact therewith. Insertion of a male luer into a slit of the elastic valve body causes expanding deformation of the elastic valve body along the protruding support surface. A flexion section is formed on a sloped surface of the protruding support surface, and the sloped surface has different tilt angles on a foot section side and on a crest section side of the flexion section.Type: GrantFiled: February 12, 2013Date of Patent: September 19, 2017Assignee: NIPRO CORPORATIONInventors: Yoshihiko Sano, Hiroshi Matsuo, Ken Suzuki

Patent number: 8129664Abstract: An induction heater which has an electrical conductor between a heating coil and a top plate. The electrical conductor has an extended portion formed downward from its outer periphery. The extended portion has a connector at its tip for coupling to a low-potential part. A thermal-connection reducing means is provided on the extended portion. A cross-sectional shape near a bent portion of the extended portion is made uniform. With the above structure, the electrical conductor has both the functions of decreasing the buoyancy and electrostatic shielding. This structure uses a smaller number of components, eliminates the risk of electric shock to the human body, and prevents uplift of an object to be heated. The thermal-connection reducing means reduces heat conduction to a connected part. Accordingly, a highly reliable and compact apparatus becomes available.Type: GrantFiled: January 27, 2006Date of Patent: March 6, 2012Assignee: Panasonic CorporationInventors: Toshihiro Keishima, Hiroshi Matsuo, Miyuki Kani
