Abstract
A solution circuit apparatus for a blood purification system having an extracorporeal blood circuit. The solution circuit apparatus includes a solution source; a warmer having a temperature sensor; a bypass branch; a delivery branch communicating with the extracorporeal blood circuit; a pump; a switch; and a control unit configured to set the solution circuit apparatus into one of a solution delivery condition and a solution stop condition. In the solution delivery condition the switch interrupts the bypass branch, and the pump delivers solution via the warmer and through the delivery branch. In the solution stop condition the switch interrupts the delivery branch, and the pump recirculates solution through the warmer via the bypass branch. In the therapy stop condition the pump rate is dependent on the output of the temperature sensor.
