Regulated pressure
The pressure is regularly checked and adjusted by Thopaz. The set pressure corresponds to
the pressure of the entire system including the patient.
Safety pressure limit
The adjustable pressure range for Thopaz is -0,1 to -10 kPa (-100 mbar, -75 mmHg). If pressure
value is greater than -7 kPa (-70 mbar, -53 mmHg) are set, the following warning appears in
the display: too high pressure can cause pain and injuries to the patient. This warning must
be acknowledged with «OK» before the pressure can be increased further.
Tube flushing
Flushing of the tubing occurs approximately every 5 minutes or when Thopaz detects
a siphon and prevents clogging of the patient tubing.
Safety chamber in canister
For appropriate, safe operation Thopaz must be in an upright position. If Thopaz tips,
the special construction of the safety chamber in the upper region of the canister protects
the hydrophilic filter from premature clogging. The pressure is maintained. Important:
immediately set Thopaz upright again. This feature is disabled if the maximum filling
capacity of the canister is exceeded.
Overflow protection / bacteria filter
A hydrophilic overflow protection / bacteria filter in the canister as well as in the tube sets
(in the connector to Thopaz) protects Thopaz from the entry of fluids and protects the
environment from contamination.
Leakage warning (does not correspond to «Leak in system» alarm)
A significant and sustained increase in the flow rate indicates that there is a leakage in
the system or an irregularity in the course of therapy. This function can be switched on
as required - see chapter 11.
