MEDBAC - Monitoring System for Medical
Air
How pure is your breathing
air?
MEDBAC breathing air control system
(Medical Breathing Air Control) protects patients against
compressed air impurity and complies with the production monitoring of
Aer
medicalis(Medical Air).
A stay in hospital is never a pleasant
experience. The pain, the worries about health, the fear of an
operation. Many people find it particularly worrying to depend on
technical systems, such as the breathing air supply in the OR(operating
room) or ICU(intensive care unit). The demands on the operation of
the life-saving systems are correspondingly high. Therefore, the European Pharmacopoeia
stipulates exact limit values for the composition of Aer medicalis, meaning the compressed
air which, in Medicine, is applied as the breathing air.
MEDBAC Medical air
monitoring
Medbac allows hospital operators to keep track of
these important gas types.
- Carbon dioxide, CO2
- Oxygen, O2
- Carbon monoxide, CO
- Water vapour, H2O
- Oil vapour/residual oil, HC
- Sulphur dioxide, SO2
- Nitrous gases, NOX
Monitoring of the values is implemented via a
microprocessor controlled online process with integrated, permanent
data storage. Therefore, sampling and laboratory evaluations are no
longer required.
The alarm values are adjustable and protected
against unauthorized access by a password. All values are displayed
numerically and graphically on a TFT screen.
Medbac is also equipped with 4~20mA potential free
contacts can be linked up with monitoring stations. Any
exceeding of a limit value will alert the clinic/hospital personnels.
Online monitoring of Medical Air
The measuring station equips with a web server. The recorded signal curves can be
displayed simultaneously via a PC. The screen display has an event
memory. In addition, data acquisition can be done via an Ethernet
connection.
MEDBAC operates in a temperature range
between 0 and +60 °C and is able to resist an operating overpressure
of 16 bar. The valid breathing air limit
