John Lumic's wheelchair
From Tardis Wiki, the free Doctor Who reference
John Lumic's wheelchair was used by its eponymous owner for automated life-support and transport. Such features included a motion control lever, breathing apparatus, and an oxygen tank. Also incorporated were doses of medication which would be taken intravenously. (TV: Rise of the Cybermen)
After Mr Crane damaged the life-support systems, Lumic, judged by his Cybermen as being "in pain", was converted into the Cyber-Controller. After conversion, the wheelchair, along with Lumic's human body, was presumably incinerated. (TV: The Age of Steel)
