Stasis chamber
A stasis chamber (also called a stasis unit, stasis pod, stasis tube, bio-pod, hibernation pod, or life support canister) was a device used to preserve life. It was often a coffin-shaped device designed for the preservation of critically injured or terminally ill patients until their conditions could be stabilized in a fully equipped medical facility.

The stasis unit suspended all ular activity and disease processes, keeping the patient from succumbing to their illness or injury for an indefinite period. The device was not meant for saving a dead patient. However, it could preserve brain activity for a few hours at most. 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. (; ; ) 

The stasis chamber at Cold Station 12 contained over eighteen thousand stasis globes, each containing an Augment embryo. An access code was required in order to enter the stasis chamber. The chamber was breached by Doctor Arik Soong and the Augment Lokesh in 2154. ()

Stasis units became standard equipment on Starfleet vessels, including the  and  starships.

The subjects of a failed Cardassian experiment involving psychotropic drugs were left in stasis tubes aboard Empok Nor when the station was abandoned. The soldiers were accidentally reawakened when a salvage team from Deep Space 9 arrived in 2373. ()

When Kathryn Janeway and Chakotay were infected with an insect-transmitted virus on a planet in the Delta Quadrant in 2372, The Doctor kept them in stasis chambers while he searched for a cure. After he was unsuccessful, the chambers were sent down to the planet so that the infection would not spread to the rest of the crew. ()

 vessels were equipped with stasis chambers. ()

In late 2374, the entire crew of Voyager entered stasis units for protection, while Voyager crossed a Mutara class nebula that emitted lethal levels of subnucleonic radiation. Only The Doctor and Seven of Nine remained awake to operate the ship. ()

The crew of the  modified a stasis chamber into a multiphasic chamber in the 2370s to first study, then exploit nucleogenic lifeforms. ()
