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. ...

This week, the Power Puff Girls worked to come up with a better design for the collection device. One aspect of the collection device that kept causing problems was the base. Having a lose base created canals and pathways that the fluid would travel through, and was not the same during each test. The new idea was to attach a bag to a thin acrylic piece shown in Figure 1. This would keep the base flat and contains a small hole in the corner for the fluid to leave the system. A more descriptive design will be shown once the apparatus is put together. Figure 1: The base portion of the collection apparatus to be placed on the magnets. Also, the girls worked to make the re-circulation device smaller. During testing, calculations were made, and we found that the rate the fluid was flowing during the previous testing was too quick. In order to reduce this, we reduced the volume of the re-circulation device and the tubing.  This should allow for the fluid to flow through at a rate o...

This past week, we tested the two different re-circulation gadgets. To be able to test them, we printed their leads to keep the flow inside.  The following is the link to the two videos that demonstrate the recirculation.  testing the two recirculation gadgets We also made a test protocol for our project:  Test Protocol: The following is the picture of our testing system:
