Publication number: 20220023523Abstract: A blood circulation system that can be connected to a human body is provided. The system may include a roller pump, a blood removal line through which blood removed from the human body flows to the roller pump, a blood transfer line that transfers blood, which is sent from the roller pump, to the human body, means for measuring a blood removal rate provided in the blood removal line to measure a blood removal rate parameter of blood flowing through the blood removal line and a control unit, wherein the control unit is programmed to control a blood transfer rate of the roller pump by controlling a rotational speed of the roller pump with a control signal, such that a transfer rate of blood flowing through the blood transfer line is synchronized with a removal rate calculated from the blood removal rate parameter.Type: ApplicationFiled: October 11, 2021Publication date: January 27, 2022Inventors: Yoshinari NIIMI, Masahiro KAMIYA

Publication number: 20200384181Abstract: An artificial heart and lung apparatus (100) includes a roller pump (120); a blood removal line (101); a first blood transfer line (104); a blood removal rate sensor (111); a control unit (140) that performs the linked control of the roller pump (120) in correspondence with a blood removal rate; and a blood transfer rate adjustment unit (160) that instructs the roller pump (120) to transfer a blood transfer rate. The blood transfer rate adjustment unit (160) includes an operation amount input unit to which an operation amount from an arbitrary circumferential position can be input, and which outputs a pulse signal according to the input operation amount, and a counter that adds and subtracts pulse signals output from the operation amount input unit, and outputs a resultant as blood transfer rate adjustment data, and the counter performs a counting operation with respect to the circumferential position of the operation amount input unit when blood transfer control transitions to the normal control.Type: ApplicationFiled: August 24, 2020Publication date: December 10, 2020Inventors: Yoshinari NIIMI, Katsunori TANAKA, Masahiro KIHARA, Munehiro KISHI, Taku MARUYA, Masanori YOSHIHARA, Masahiro KAMIYA

Patent number: 10786617Abstract: The preset invention discloses an artificial heart and lung apparatus (100) including a roller pump (120); a blood removal line (101); a first blood transfer line (104); a blood removal rate sensor (111) and a control unit (140) that performs linked control of the roller pump (120) in correspondence with a blood removal rate. The control unit (140) is capable of detecting that the blood removal rate deviates from a blood removal condition set in advance, and out-of-set condition blood removal is performed.Type: GrantFiled: August 20, 2015Date of Patent: September 29, 2020Assignee: SENKO MEDICAL INSTRUMENT MFG. CO., LTD.Inventors: Yoshinari Niimi, Katsunori Tanaka, Masahiro Kihara, Munehiro Kishi, Taku Maruya, Masanori Yoshihara, Masahiro Kamiya
