Abstract

A medical fluid system including: fluid containers and a tube extending from same, each tube including a cap; a pumping cassette including port spikes; a medical fluid machine including: occluders; a shuttle configured to receive the tubes, wherein each tube is associated with one of the occluders; a driving mechanism translating the shuttle; a cap removal device between the cassette and the shuttle; and a control unit programmed to cause: (i) the occluders to pinch their tubes, (ii) cause the driving mechanism to translate the shuttle towards the fluid pumping cassette, the cap removal device engaging the tube caps, (iii) the driving mechanism to translate the shuttle away from the fluid pumping cassette and cap removal device, pulling the tube caps off of the tubes, and (iv) the driving mechanism to translate the shuttle back towards the fluid pumping cassette for the port spikes to spike the occluded tubes.
