3.3 Gas feed
In order to operate the medin-NC3®, it must be supplied with oxygen from an external source that meets the
following condions:
Medicinal oxygen:
- 300 to 700 kPa (=3.0 to 7.0 bar)
- Oxygen content: ≥ 99.5%
- H2O ≤ 67 ppm (V/V) (free from condensate)
Ambient air:
- Provided by an integrated blower
Aenon:
The funconality of the medin-NC3® can only be guaranteed if the oxygen supplied to it is free from condensate
water, oil and contaminants. If this is not guaranteed, the medin-NC3® could be damaged.
In order to avoid res, oxygen must not come into contact with oil or grease. It is therefore essenal to ensure that
all parts of the medin-NC3® and the CPAP system which come into contact with oxygen (e.g. gas feed tubes, O
2
inlet
to the medin-NC3®, paent outlet, paent tubes and Medijet®) remain free from oil and grease.
Gas feed connecons:
The medin-NC3® can be ed as standard with NIST or DISS gas feed connecons as the customer prefers. The
tube kits to connect the device to the external gas source must also meet the selected standard.
3.4 External data interfaces
The medin-NC3® can be connected to a system for archiving and processing paent data.
Aenon:
Only devices and systems which are approved for medical use and which meet the relevant electrical safety and
EMC standards may be connected to the medin-NC3® data interfaces. Integraon into such systems can lead to risks
for paents, operators or third pares which were not previously known. The person in charge of the integraon
must determine, analyze, evaluate and manage these risks.
Changes to the system can lead to new risks. Such changes include, for example:
• Changes to the conguraon
• Connecon of addional elements
• Removal of elements
• Update of connected devices
• Upgrade of connected devices
3.4.1. RS232 data interface
The RS232 data interface of the medin-NC3® can be used to retrieve internal device data. In addion, there is the
opon to prompt an export of the trend data in the trend by pressing the corresponding buons. The interface
delivers live data during normal operaon or trend data during export which must be received and saved by a
computer or data management system. Serial data with the following sengs are issued:
