3 Using the chair
3.1 Precautions for use – basic safety rules
Before seating a patient, make sure that both axle locks are in their locked
positions.
Always gently seat the patient in the chair. Do not let the patient fall into the
chair. It can result in damaging or unbalancing the medical device and can
result in the patient falling on the ground. Never release the primary frame
lock when there is no patient in the chair.
Be aware that the worst mechanical position is secondary frame horizontal
with the patient facing the primary frame. In this position, be careful that the
patient doesn’t move excessively and do not apply strong shocks on the
medical device.
Whenever a position is selected following rotation of the secondary frame,
it is important to check that the mechanical locking system is correctly
engaged. Before the primary frame is released, the patient should be
informed what type of movement to expect as well as of the probability of
vertigo during the maneuver. Throughout the various maneuvers, it is
recommended that the operator keeps talking with the patient to provide
reassurance.
Never release both axles of rotation at the same time.
The operator must never be alone in the room with the patient when using
the chair. In case of inability on behalf of the operator during a session, a
secondary operator will have some instructions fixed to the wall to explain
how to free the patient.
Always use the handles to manipulate the device. Failure to use the
handles during maneuvers may incur pinch / trapping danger and potential
damages.
During maneuvers, mind not to pull out the wire of the foot switch.
No one except the operator and the patient may stand closer than 2 meters
from the chair.
