As an engineer at Medisystems, I was lucky enough to work on a hemodialysis bloodline for patients with renal failure that improved patient safety and reduced set up complexity for the technicians. While I had partial design input into the bloodless pressure interface (top left picture-used to measure the blood pressure coming out of the patient or the “arterial side,” and post dialysis pump (“venous side”) and the needleless injection site, my main contribution was to the vortex air trap (lower right). The design of the downspout for the blood flow was key to setting up a vortex to trap any air bubbles that may be introduced by an injection or other means. The vortex would draw the air bubbles into its eye and lift them to the top of the chamber thusly reducing machine shut off and increasing safety of the patient.
