Disaster and Non-Electrified CPAP / Auxiliary Breathing Device Concept for Developing AreasUtilizing the motor structure devised the other day.At the same time, devising a CPAP system that does not use electricity at all at night.Evaluation: 4.2.

The structure is simple and can be made with commercially available parts. Reliability testing of safety valves and pressure control is key.It is effective as an alternative to CPAP in disaster or power outage environments. However, comfort verification during long-term use is necessary.It is easy to deploy on-site and has low training costs. Optimization in terms of weight, size, and hygiene management is needed in the future.
