4.3 Intended purpose
4.4 Intended patient population
A travel drive is an electrical transport device and is attached to a manual wheelchair. The objective of
the electrical transport device is to make movement with a manual wheelchair easier for a self-propelled
person and to increase or fully take over the force generation for the movement of the wheelchair. This
shallmaintainautonomousmovementandincreasemobilityandexibilityforthepatient.
The travel drive can be used indoors and outdoors on level surfaces and upward and downward slopes.
The devices are controlled by the patients themselves.
The intended patient population includes all persons who are able to sit independently.
Users of the SERVO may have a maximum total weight of 200 kg together with their wheelchair and the
SERVO travel drive.
