Stasis chamber

Stasis chambers (also called stasis unit, stasis pod, stasis tube, or bio-pod) were a coffin-shaped device designed to preserve life if it's occupant were critically-injured or terminally-ill until their conditions could be stabilized in a fully-equipped medical facility.

Specification
These stasis units suspended all cellular activity and disease processes, keeping the patient from succumbing to their illness or injury for an indefinite period of time. The device was not meant for saving a dead patient, except in a few cases. Time was required to get the ailing patient into the unit before they succumbed, presumably so that more time was available as they came out of stasis to effect proper treatment.

Stasis units were standard equipment on Earth's and Starfleet's DY-100, Galaxy, Defiant, Danube, and Intrepid-class starships.

History
The earliest use of this technology could be traced back to the 15th century. In 1484, a Vaadwaur battalion used stasis units to survive the bombardment by the Turei and their allies. They had planned come out of stasis 5 years after the bombardment, but their controls were damaged and they stayed in stasis for 892 years. They were by the USS Voyager (NCC-74656) in 2376.

In the latter half of the 20th century, Earth equipped it DY-100 ships with these units because of long voyages between planets. One of the last Augment dictators, Khan Noonien Singh had himself and his crew put into stasis chambers aboard the SS.
