4.2 Adaptation
First ventilate the system until the patient
sinks into the material by adding air via the
valve (
A
) using the hand pump included in
delivery. A gel-type consistency should be
aimed for.
Avoid bloating of the system.
Prior to positioning the patient, adjust the
support system so that the granules in
the cushion cannot slip about. This takes
place using the pump included in delivery
through ventilation or the removal of air
through vacuum so that a soft, defor-
mable consistency is achieved. Assist the
patient to sink into the material by pus-
hing the filling material under the pati-
ent or away as applicable. In this way, you
can for example support a patient with severe scoliosis by pushing the
system granules into the required areas in advance. For prone position,
you should push the granules of the first third of the system together before
placing the patient into the cradle in order to create a wedge shape. As
soon as the required sinking depth is achieved, you can start with correc-
tion work.
The aim is to achieve as symmetrical a position as possible within the scope
of the illness symptoms. To do this, it is necessary to model the filling material
from the outside towards the patient in the manner described above. For sta-
ble lateral guidance, you require a support surface with a large volume. You
should shift the material required for the purpose from the edges of the system.
Once the required correction has been achieved, remove the air via the
vacuum system using the pump until the achieved firmness no longer per-
mits deformation. If you subsequently wish to change the achieved po-
sition again, add just enough air with the pump until the system can be
deformed once more. Then the system is vacuumed to its maximum
extent once more. If the intention is to permanently preserve the po-
sition this way, it is essential that the host connection between the
pump and the system are interrupted, as otherwise small quantities
of air can penetrate into the system via the valve.
The valve only closes tightly when the hose is removed from the
quick coupling.
