  • Patent number: 6475191
    Abstract: An indwelling needle assembly includes an outer needle hub having an outer needle fixed to the distal end portion thereof, an inner needle hub having an inner needle at the distal end portion thereof, and a needle guard that can accommodate the inner needle and the inner needle hub therein. The needle guard has a double-tube structure including an inner tube and an outer tube, and a connector for connecting the inner needle hub and the inner tube via the proximal end of said needle guard. The needle guard is also expandable by sliding the outer tube toward the proximal end of the inner tube. When the needle guard is extended, the inner needle hub is slid in the needle guard toward the proximal end of the needle guard by the connector.

  • Patent number: 5886780
    Abstract: A refractometer comprising an optical pattern-beam projection system for projecting a pattern,light beam onto the fundus of a tested eye to measure refractive power of the tested eye, and an optical light-receiving system for receiving the pattern light beam reflected at the fundus to compute the refractive power of the tested eye. A deflecting member is inserted into an optical path of the optical pattern-beam projection system for deflecting the pattern light beam with respect to an optical axis of the optical pattern-beam projection system and then projecting the deflected pattern light beam onto the fundus.
