発明の名称 (英語) IMPLANTABLE HEMODIALYSIS DEVICE NEW
発明の概要(英語) [Problem] To provide a hemodialysis device that reduces the risk of accidents and infections and can remove waste products to a sufficient degree.
[Solution] A hemodialysis device which includes: a hemodialysis filtration membrane 5 inside a first housing 3; an arterial-side blood circuit 7 for flowing blood into the first housing 3; an intravenous side blood circuit 11 for flowing out the blood from the first housing 3; a dialysate introducing unit 21 that is connected to the first housing 3 and introduces a dialysate into the first housing 3; a dialysate discharging unit 31 that is connected to the first housing 3 and is for discharging the dialysate that has been through the housing; and an extracorporeal first connecting unit 25 for connecting a dialysate feed unit of an extracorporeal dialysate feed device with the dialysate introducing unit 21.
従来技術、競合技術の概要(英語) BACKGROUND ART
Patent Publication 5385763, the hemodialysis device is described. A patient in need of artificial dialysis 3 and 2 or once the visit is not without artificial dialysis. For this reason, artificial dialysis by the visit, the patient's QOL is reduced significantly. For this reason, a state in which the home dialysis patient home dialysis is performed has been proposed. Home dialysis, hemodialysis treatment or peritoneal dialysis therapy to a patient at home can be performed. Home dialysis, compared to artificial dialysis by the visit, the degree of freedom in life, relatively slow degradation of kidney function is called. On the other hand, also in home dialysis, the dialysis device and the operation itself, require puncturing. Therefore, dialysis of the attendant is necessarily in the home becomes necessary and, an accident risk of infection.
Japanese Patent Laid-Open Patent Application 2017-158814, the implant is an artificial kidney blood filtration device of the type described. By using the artificial kidney dialysis was continued for 24 can be performed, a small risk of accident or infection. On the other hand, in the artificial kidney, such as creatinine and urea components to remove waste products of the performance may not be sufficient.
