Medical Machine

The Medical Machine consists of a sealed pod filled with a healing liquid. An injured individual is placed inside, and the chamber is sealed while the restorative fluid accelerates the body's natural healing processes. Depending on the severity of the injuries, recovery can take anywhere from minutes to several hours. The technology was standard equipment aboard Frieza Force vessels and bases.

Vegeta was placed in a Medical Machine after arriving on Planet Namek with severe injuries. The healing process inadvertently benefited him due to the Saiyan trait of growing significantly stronger after recovering from near-fatal wounds. Goku also used one of these machines on Frieza's ship after his brutal battle with Captain Ginyu.

The machines saw continued use beyond the Namek Saga. In Dragon Ball Super, Tagoma and Seven-Three were shown using similar technology. Bardock was also depicted using a Medical Machine in the TV special "Bardock: The Father of Goku," placing the technology's usage as far back as before Planet Vegeta's destruction. The Medical Machine functions as a technological counterpart to Senzu Beans and Dende's healing abilities.
