Patent number: 8834400Abstract: Artificial kidney for gradual, and at least semi-continuous, blood treatment, wherein a blood stream is fed from a body of a living human or animal being into the artificial kidney, where anticoagulation is first effected, blood cells and molecules of large and medium molecular weight, such as proteins, are then primarily separated from plasma and fed back to the blood stream, regulating a water and salt balance by diverting excess plasma water and further removing from the blood stream, plasma or plasma water accumulated and toxic substances, by removal of specific electrolytes and waste products and wherein purified or partially purified plasma and plasma water is being carried back to the blood tract of the body.Type: GrantFiled: May 9, 2012Date of Patent: September 16, 2014Assignee: Relitech B.V.Inventors: Franciscus Peter Houwen, Henk Van Middendorp, Jacobus Cornelis Musters

Publication number: 20110161016Abstract: The invention relates to a system and method for analyzing a fluctuating flow of a mixture of gases having an optionally variable frequency. The system can be used to determine momentary presence and quantity of at least one selected gaseous component in the fluctuating flow. The system uses at least one electronic sensor adapted to generate a measurement signal representative of at least one of the presence and quantity of the at least one gaseous component. The at least one electronic sensor has a response rate slower than the frequency of the fluctuating flow and the measurement signal is subjected to a correction to construct a momentary corrected signal that equals, or at least closely resembles, at least one of the momentary presence and quantity of the at least one gaseous component. In particular the correction includes a compilation of inverse filtering and moving average filtering.Type: ApplicationFiled: June 10, 2009Publication date: June 30, 2011Applicant: Relitech B.V.Inventors: Henk Van Middendorp, Johannes Martinus Esse Van Den Burg, Adrianus Lambertus Johannes Maria Nikkelen, Gerrit Van Den Brink
