Definition of vacuum
By the application of medical aspiration devices, vacuum is normally given as the difference
(in absolute figures) between absolute pressure and atmospheric pressure or as negative values
in kPa. In this document, the indication of -10 kPa for example always refers to a pressure range in
kPa below atmospheric ambient pressure (according to EN ISO 10079:1999).
Regulated pressure
The pressure is regularly checked and adjusted by Thopaz + . The set pressure corresponds
to the pressure of the entire Thopaz + system.
Safety pressure limit
The adjustable pressure range for Thopaz + is -0,1 to -10 kPa (-100 mbar, -75 mmHg, -100 cm-
H2O). If pressure values greater than -7 kPa (-70 mbar, -53 mmHg, -70 cmH2O) are set, the
following warning appears in the display: too high pressure levels can cause pain and/or serious
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 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 function is disabled if the maximum filling capacity of the canister is
exceeded.
