Abstract
A treatment system for performing a treatment on a patient may include a treatment fluid preparation device having a pump connected by a fluid channel to a reservoir of a source fluid, the pump conveying the source fluid from the reservoir, through a filter, and combining the source fluid with a concentrate by pumping the source fluid with the concentrate to form a treatment fluid in a batch container. The treatment fluid preparation device may have a controller that controls a heater, the pump, and a memory. The controller starts the heater to warm the treatment fluid in the batch container at a time that is responsive to the treatment time stored in the memory. The controller also detects a pressure property of the filter to determine its integrity and outputs an indication of a failed batch if the pressure property indicates the integrity of the filter is insufficient.
