Patent number: 11331454Abstract: The present invention provides a needle tip protector of a novel structure for an indwelling needle, which enables improvements in safety, etc. as compared with conventional needle tip protectors. A needle tip protector 10 for an indwelling needle includes a tubular peripheral wall 58, and is externally attached over a needle hub 22 of an indwelling needle 16 and moved toward a needle tip 14 side so as to cover the needle tip 14. Detents 74, 74, which are to be detained with the needle hub 22 at a position in a movement of the protector toward the needle tip 14 side of the indwelling needle 16 so as to inhibit backward movement of the protector to the proximal end side of the indwelling needle 16 and to prevent the needle tip 14 from being reexposed, are formed within an inside enclosed by the peripheral wall 58, and are integrally molded with the peripheral wall 58.Type: GrantFiled: June 2, 2017Date of Patent: May 17, 2022Assignee: NIPRO CORPORATIONInventors: Yoshiei Ono, Kohzo Ishikura, Tatsuya Kudo, Takeshi Yamaguchi

Patent number: 9101749Abstract: An indwelling catheter including: a hollow catheter base having a tip and a back end, the back end being able to receive and connect a male connector; a tube provided at the tip of the catheter base; a flexible hemostasis valve installed inside the catheter base; a pusher installed at a back of the hemostasis valve; and a pusher guide installed between the pusher and the catheter base. The pusher has a hollow constitution whose taper reduces in diameter facing its tip. The pusher guide is able to restrict a position of the pusher at a first position where the pusher does not push open the hemostasis valve and a second position where the taper of the pusher is positioned inside the hemostasis valve and pushes open the hemostasis valve.Type: GrantFiled: October 2, 2012Date of Patent: August 11, 2015Assignee: NIPRO CORPORATIONInventors: Hiroyuki Nakagami, Tatsuya Kudo, Tomohiro Uchimura

Patent number: 8900199Abstract: A needle tip protector is configured in such a manner that a flexible plate is provided to a protector main body over which an action ring is mounted and that the flexible plate undergoes flexural deformation when the action ring is moved to a predetermined position relative to the protector main body. When the flexible plate undergoes flexural deformation, a needle tip of an inner needle to which the protector main body is mounted is protected by a protection part placed at a distal end of the flexible plate. The needle tip protector is also provided with a slip-stop mechanism for preventing the action ring from slipping out of the protector main body in an axial direction of the needle.Type: GrantFiled: October 1, 2009Date of Patent: December 2, 2014Assignee: Nipro CorporationInventors: Katsunori Kawai, Tatsuya Kudo, Hiroyuki Nakagami
