The Life-Preserving Device is a device used by Freeza's Army.
Vegeta used it after the battle with the Dragon Team on Earth and ultimately being left on the brink of death after by Great Monkey Son Gohan. It's attached in the small spaceships used by Freeza's men. The oxygen from the pipe serves to artificially aid one's breathing.
