AI Technical Summary
Existing ventilators rely on oxygen cylinders for oxygen supply, resulting in large and heavy devices that limit their application in oxygen-scarce areas, especially in high-altitude regions where their usage time is short and they are inconvenient to carry.
The device employs an integrated adsorber and a breathing chamber structure that mimics a lung. It adsorbs carbon dioxide and uses oxygen from the air for assisted breathing. Combined with the clamping rib design of the shell structure, the device achieves compactness and stability.
It enables autonomous assisted breathing in high-altitude areas, reduces dependence on oxygen cylinders, improves the structural stability and portability of the device, and extends its usage time.
