APPLICATION OF M.blue plus Instruments

The M.blue plus Instruments may only be used
by trained specialist personnel. The selected
pressure level of M.blue can be determined,
adjusted and monitored using the M.blue plus
Instruments. The M.blue plus Compass is
used for localising and reading the adjustable
gravitational unit of M.blue.

The opening pressure for the adjustable grav-
itational unit can be changed before or after
implantation. It is preset by the manufacturer to

1. Localisation
When the M.blue plus Compass is opened, a
circular template becomes visible with which
you can localise the valve in the patient's head
using your index finger (fig. 9).

The direction markings on the template show
the flow direction.
2. Test procedure
In order to determine the selected pressure
level, the compass is then closed again. The
float gauge should now be centred by moving
the instrument in the designated circular mark-
ing (fig. 10). Once the float gauge is centred,
the currently set opening pressure of the gravi-
tational unit can be read off via the line mark on
the float gauge (fig. 10).
