Stasis Unit
From Star Trek : Freedom's Wiki
Containing device that supports life by slowing down all biological activity within the perimeter of the unit. The device is designed to work with stasis medication, but can work without it.
Stasis units contain a generator that will support life at very decreased rates and are used for transport of critically injured patients for treatment at a medical facility. Portable stasis units can also be used in the field, coming both in collar form (Class B) and 5cm x 5 cm form (Class C).
