Oxygen cannulas are used to deliver supplemental oxygen to patients who require oxygen therapy. Even though the tubing is made of a lightweight material, it can cause soreness behind the ears due to elongated periods of pressure. The tube hooks around the back of the patient's ears and the cannula rests inside the nostrils. The opposite end is attached to an oxygen concentrator. This tube on average carries up to 5 liters per minute which can increase the pressure on the back of the ears. The goal of our project is to figure out a system that could decrease the pressure on the ears. The immense pressure causes sore ears which can be very painful for the patient during and after the use of the device. The challenges that we expect to face are to figure out which material to use to design our product, where it should be placed and how lightweight we can possibly make the design since more weight would only be a burden. The final deliverable will require 3D printing and the design will be made through CAD or a related program. The result will be to produce a product in which patients can use to reduce soreness and discomfort. This issue is faced by many people across the world in hospitals, healthcare centers or even at patients who live at home.
