Abstract: An extracorporeal circulation blood or treatment device (100) comprising an arterial pressure sensor (112) and a blood pump (111) is set up to determine amplitude variation and frequency of the pressure signals received from said arterial pressure sensor (112), calculate a parameter value based on said amplitude variation and said frequency, and issue an alarm if the parameter value exceeds a pre-set threshold value. Such detection aims at monitoring the occurrence of oscillating pressure signals. Such signals indicate an increased risk for hemolysis.

Abstract: Water systems, medical equipment, and apparatus for thermal disinfection comprise a control unit which starts the disinfection of a fluid path by controlling a heating unit to heat water and controlling an actuator to enable heated water to flow into the fluid path. The control unit reads the temperature as measured by a temperature sensor during the disinfection and calculates an achieved disinfection dose. The achieved disinfection dose is compared with a set disinfection dose and the disinfection is discontinued if the achieved disinfection dose corresponds to the set disinfection dose.

Abstract: The present invention relates to a method of controlling a dialysis apparatus, which can be used, e.g., for hemodialysis, hemodiafiltration, or hemofiltration. Numerous alarms occur during treatments creating additional workloads for the operator. The present method of controlling the apparatus allows an automatic switch from a first control mode to another, thus allowing the treatment to continue without operator influence.

Abstract: A method and apparatus of priming or rinse back of an extracorporeal circuit using a dialysis machine comprising a dialysis liquid preparation system. The dialysis machine is used to prepare a saline solution on-line. The extracorporeal circuit is connected to the dialysis machine and primed with the saline solution.

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.
