The oxygen nasal suction tube is the most comfortable oxygen inhalation tool. It has a variety of lengths to transfer oxygen from the oxygen meter of the buoy-type oxygen inhaler to the nostril of the oxygen inhaler, inserting the nostril instead of blocking the nostril. It's like putting a glass tube in a water glass and injecting paint into the water through the tube. The faster the tube injects the paint, the faster the color of the water changes. When we breathe, when we inhale, oxygen will be mixed in the air and inhaled into the lungs. The greater the flow of oxygen, the more mixed oxygen. The more, the oxygen concentration in the air will continue to increase, thereby realizing the adjustment of the oxygen concentration.
