O2 self-save device

According to World Health Organization data, approximately 400,000 people worldwide die from fires each year, with 75% of these deaths being attributed to smoke and toxic gases. Therefore, we aim to design an "O₂ self-save device".

This device through the redox reaction of carbon dioxide and water vapor with potassium superoxide, a clean oxygen source is produced for the victim to breathe, reducing the risk of choking or even death for people on the fire scene. It is equipped with integrated goggles, oxygen masks, Lights, sirens, and other equipment that can reduce fire hazards as much as possible and improve fire survival rates.

The overall design is designed to be convenient, fast, intuitive to use, and effective in protection. It is hoped that it can reduce the number of victims who die due to thick smoke, improve the survival probability at the fire scene, prolong the waiting time for rescue, and increase the chance of self-escape.

The product is mainly composed of a mask, a chemical tank, and an airbag bag. When you open the box, you will pull out the latch at the same time, and the airbag will be inflated. There is a disposable seal on the top of the box to confirm whether the product has been used, and the outer box will be painted with luminous light. The paint makes it easier to know the location of the self-rescuer in the dark. The mask is used to isolate smoke from irritating the eyes. The light bar above can illuminate the escape route. The reflective strips and alarms on the straps allow rescuers to know more smoothly about the position of the trapped person.

When normal breathing begins, the carbon dioxide and water vapor in the human mouth will be sent to the chemical tank through the breathing tube to start a reaction and will be transferred to the chemical tank through the one-way valve. The reaction will then be transferred from the outlet on the other side to the airbag and pass through the particle filter. Then it passes to the breathing tube and enters the human mouth.
