The attachment plate (shown in grey) is custom designed to a 3D scan of the patient's arm, and contains attachment points for rubber tubing and thrill motors. The rubber tubing allows for fluid to be pumped through this vein, and the thrill motors give a realistic sensation of blood pumping through the arm. A sheet of silicone covers the device on top, and creates a skin-like barrier. The patient can then practice using their needle, and learning what it is like to put this needle through skin, and maneuver it into the vein. The rubber and silicone parts are removable by design, and can be replaced when needed to allow the patient ample practice and mistakes before performing the procedure on themselves.
