The purpose of this study was to develop disposable oxygen cylinder residual alarm with the light and sound for the oxygen cylinders as part of the medical engineering collaboration. We co-developed, with two local manufacturing companies, the original alarm device, which is measured in the remaining quantity of the gas stored in an oxygen cylinder and is visually displayed in an LED and sound, and performed verification tests through the oxygen cylinders managing inside the hospital. As a result, we could appropriately monitor the remaining quantity of the oxygen cylinder through the LED and the sound without depending on a visual check of a user, and also could reduce the event of an empty oxygen cylinder and a burden on a monitoring person when simultaneously monitoring the remaining quantity of the oxygen cylinder. This device was thought to improve patient safety during oxygen therapy by successfully establishing a speedy and appropriate process.
