Patent number: 7780848Abstract: A single needle hemodiafiltration apparatus is provided. The single needle hemodiafiltration apparatus includes circuits for blood supply from a patient and blood return to a patient, a dialysis fluid supply system for supplying a dialysis fluid, and a system for controlling the blood flow and dialysis fluid flow in a separation device which is equipped to perform filtration and back-filtration operations. A controller is provided that controls, in a series of coordinated operations, the flow of blood from the patient into the separation device, the flow of filtration fluid and back filtration fluid, and the return of blood to the patient.Type: GrantFiled: June 18, 2004Date of Patent: August 24, 2010Assignee: JMS Co.Inventors: Sung-Teh Kim, Kunihiko Yamanaka, Naritomi Maeda, Katsunori Masaoka, Kayoko Segawa, Chieko Yamamoto

Patent number: 7441666Abstract: It is intended to provide asymmetric porous films which are usable in blood dialysis, plasma separation, etc. and particularly excellent in the performance of selectively separating (fractionating) plasma protein, show little endogenous coagulation, complement or quinine activily and have an extremely high biocompatibility. Porous films made mainly of a synthetic polymer and having an asymmetric structure wherein, in the sectional structure, a dense layer substantially not charged at least on the outermost surface is provided in the side on which a liquid to be treated is loaded and at least part of the film other than the outermost surface is negatively charged. In the above films, the dense layer non-charged at least on the outermost surface serves as a size barrier while the part of the film other than the outermost surface serves as a charge barrier.Type: GrantFiled: April 18, 2002Date of Patent: October 28, 2008Assignee: Asahi Kasei Kuraray Medical Co., Ltd.Inventors: Sung-Teh Kim, Chieko Yamamoto, Toshinori Koizumi, Masatoshi Saitoh, Shunji Maniwa

Publication number: 20080251433Abstract: Provided is a hemodialyzer in which deterioration in membrane performance of a hollow fiber with time can be grasped accurately during dialysis and the performance can be recovered quickly and positively. The hemodialyzer, constituted by connecting an artery side blood circuit (2) having a blood pump (7) to the artery side of a dialyzer (1), connecting a vein side blood circuit (3) to the vein side of the dialyzer (1), and connecting a dialysate supply line (4) and a dialysate discharge line (5), respectively, to the side face of the dialyzer (1), is provided with a detector (15) for determining the pressure in the blood circuit, and a detector (16) for determining the pressure in the dialysate line, in which transmembrane pressure is calculated based on the determined pressures, and reverse filtering is performed by the dialyzer (1) when the transmembrane pressure exceeds a predetermined level.Type: ApplicationFiled: March 31, 2006Publication date: October 16, 2008Applicants: JMS CO., KITAKYUSHU INSTITUTE OF BIOPHYSICSInventors: Sung-Teh Kim, Chieko Yamamoto, Kayoko Segawa, Kunihiko Yamanaka, Katsunori Masaoka

Publication number: 20080156729Abstract: An apparatus for blood dialysis composed at least of a hemodialyzer (a) whereby blood is brought into contact with a dialysate via a semipermeable membrane and thus purified; a blood circulation system (b) composed of a blood circuit in the arterial side whereby blood is taken out from a patient and flown into the hemodialyzer and another blood circuit in the venous side whereby the blood flown out from the hemodialyzer is returned to the patient; a dialysate supplying/discharging system (c) for supplying and discharging the dialysate composed of a dialysate-supply line for supplying the dialysate to the hemodialyzer and a dialysate-discharge line for discharging the dialysate flown out from the hemodialyzer, and a means (d) of controlling the back-filtration speed. Owing to this constitution, individual steps from the preparation of the dialysis (treatment) to the completion of the treatment and the change from a specific step to the next step can be safely, surely and quickly carried out in most cases.Type: ApplicationFiled: September 27, 2007Publication date: July 3, 2008Applicants: JMS CO., LTD, KITAKYUSHU INSTITUTE OF BIOPHYSICS CO., LTD.Inventors: SUNG-TEH KIM, MASAHIRO TAOKA, CHIEKO YAMAMOTO, Kunihiko Yamanaka, KATUNORI MASAOKA

Publication number: 20060138049Abstract: A novel single needle hemodiafiltration apparatus and a novel single needle hemodiafiltration method for purifying blood with excellent removal performance via extracorporeal circulation with a single needle type are provided. The single needle hemodiafiltration apparatus includes a blood supply system for supplying blood, a dialysis fluid supply system for supplying a dialysis fluid and a system for controlling a movement of a fluid between the two supply systems, and a filtration/back-filtration liquid supply unit provided in the dialysis fluid supply system is controlled in conjunction with a blood pump provided in the blood supply system so that blood is removed from the body synchronously with the filtration and returned to the body synchronously with the back-filtration, thereby enabling extracorporeal circulation with the single needle. At a time of filtration, substances are removed by diffusion and ultrafiltration. At a time of recirculation in the blood circuit, substances are removed by diffusion.Type: ApplicationFiled: June 19, 2003Publication date: June 29, 2006Inventors: Sung-Teh Kim, Kunihiko Yamanaka, Naritomi Maeda, Katsunori Masaoka, Kayoko Segawa, Chieko Yamamoto
