Abstract
Systems for controlling medical treatment procedures such a dialysis are disclosed, including a fluid flow inlet for feeding a treatment fluid to a medical treatment device such as a dialyzer, a fluid flow outflow path for withdrawing contaminated fluid from the medical device, a diversion channel for diverting a fluid flowing in the fluid flow inlet path from a point in that path upstream of the medical treatment device in order to bypass the medical treatment device, and a solvent supply, a cartridge containing a cleaning composition, and a connector for connecting the cartridge to the solvent supply and to the fluid flow inlet path, so that solvent can be mixed with the cleaning composition in the cartridge, and the mixture can be passed through the fluid of inlet path in order to clean the fluid flow in the path when the diversion channel diverts the fluid past the medical treatment device. Methods for controlling the flow of treatment fluids through medical treatment devices are also disclosed.
