Publication number: 20230015695Abstract: The present invention provide a puncture instrument capable of administering (supplying) a drug solution. The puncture instrument includes a puncture tip section (2); a first tubular body (3) connected to the puncture tip section (2) at the distal end; and an outer tubular body (5) at least partially covering the first tubular body (3). The first tubular body (3) is formed to be rotatable around an axis along the longitudinal direction. The first tubular body (3) has an outer diameter smaller than an inner diameter of the outer tubular body (5). A drug solution supply path (5a) is provided on the outside of the first tubular body (3).Type: ApplicationFiled: June 28, 2022Publication date: January 19, 2023Inventors: Shuji NAKAMURA, Ken MASAMUNE, Kohei MIKI, Katsuyuki SADO, Hirokazu TAKAGAWA, Fumiya IWASHIMA, Akihiro NABESHIMA

Patent number: 11192121Abstract: A blood component separator (1) includes a blood storage vessel (20) that includes a first storage part (21) and a second storage part (22), a slider (30) movable from the first storage part to the second storage part, and a flow path (40f) for communicating an inside and an outside of the storage vessel. When the slider is in the first storage part, the first storage part and the second storage part are in communication with each other. When the slider is inserted into the second storage part, a liquid-tight seal is formed between the slider and the inner peripheral surface of the second storage part and the communication between the first storage part and the second storage part is blocked by the slider. The slider is movable in the second storage part while maintaining the liquid-tight seal between the slider and the inner peripheral surface of the second storage part.Type: GrantFiled: December 20, 2016Date of Patent: December 7, 2021Assignee: TRANSELL Co., Ltd.Inventors: Nariyuki Hamada, Shuji Nakamura, Katsuyuki Sado, Kenta Kaneda
