design description

To keep the tubing from moving and potentially causing accidents, and to keep blood moving by gravity, blood will be drawn from one arm and injected to the other arm ( possibly into the back of the hand vein). The blood-nanoparticle mixing gadget and the collection part will be held behind the chair in a bx-like apparatus.

The picture on the left shows the big picture of the mixing apparatus. 
It will operate by 2 Arduino-controlled servo motors tilting the plate that has the blood-containing bag on top of it. The motors will be in pulley style to ensure that the plate is tilted in all directions. The motors will move the plate by the straps attached to the plate.

The image on the left is of the servo motor. The 2 motors will be attached to 3D printed pieces that rotate the plate.

Here are the front and top views of the 3D printed parts that will be attached to the motor. They will have a rod in the center to allow for rotations.

The figure on the left is of the acrylic plate that will be holding the blood-filled bag. The bag will be clipped to the plate to allow easy removal and avoid bag movements while mixing. The plate also has holes to attach straps and the clips.
