The innovative Medbac breathing air control system (Medical Breathing Air Control) protects patients against impure compressed air and complies with the monitoring requirements of "Aer medicalis".
A stay in hospital can be a worrying experience. Many people find it particularly hard to depend on technical systems, such as the breathing air supply in an operating room or 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 the so-called "Aer medicalis", meaning the compressed air which, in Medicine, is applied as breathing air.
MedBAC from Beko is a compressed air monitoring system which constanly observes the content and delivery of medical compressed air.
Uninterrupted delivery is also an important factor in the supply of medical compressed air. The high sensitivity of MedBAC helps to immediately detect malfunction, such as an increase in unacceptable gasses of loss of flow or pressure, notifying the service provider via an alarm system. Patients, as well as medical devices are thus protected and reassured at all times.
Sampling unnecessary
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 unauthorised access by a password. All values are displayed numerically and graphically on a TFT screen. The exceeding of a limit value will immediately be detected by the clinic personnel, as the respective value will light up red and signalling contacts will be switched on.
The measuring unit is equipped 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 archiving with automatic read-out is possible on a central server via Ethernet. Medbac operates in a temperature range between 0 and +60 °C and is able to resist an operating overpressure of 16 bar.
