15. A patient transport apparatus comprising:
-
a support structure having a head end, a foot end opposite said head end, a right side extending between said head end and said foot end, and a left side extending between said head end and said foot end, opposite said right side; a drive wheel assembly comprising; a drive wheel; and a powered drive system coupled to said drive wheel; a pair of handles each having a first end coupled to one of said head end or said foot end of said support structure, said pair of handles also having a second end opposite said first end; and a rotatable throttle coupled between said second ends of said pair of handles, wherein a length of said rotatable throttle, defined lengthwise between said second ends of said pair of handles, is sufficiently long such that a user may operate said rotatable throttle from a position along said right side or said left side of said support structure. - View Dependent Claims (16)
