Blood treatment systems

A blood treatment system comprising:

• A dialysis treatment apparatus comprising:
• A housing;
• A bundle of hollow fibers within an interior of the housing, the hollow fibers defining lumens;
• An arterial patient line connected to a first end of the housing, the arterial patient line configured to be connected to a vasculature of a patient and comm unicative with the lumens of the hollow fibers;
• and
• A venous patient line connected to a second end of the housing opposite of the first end, the venous patient line configured to be connected to the vasculature of the patient and communicative with the lumens of the hollow fibers,
• Wherein the arterial and venous patient lines are each less than a meter in length;
• A blood treatment machine comprising:
• A blood treatment module including a structure for releasably coupling with the dialysis treatment apparatus;
• A blood treatment machine console that controls the treatment module;
• and
• An arm extending between the blood treatment machine console and the treatment module such that the treatment module is cantilevered from the blood treatment machine console by the arm, wherein the arm comprises one or more sensors operable to determine motion of the treatment module in relation to the blood treatment machine console.
