Hospital Network - Brainlab Buzz Navigation System And Technical User Manual

Hospital Network

4.7 Hospital Network
Network Requirements
The hospital network must comply with the following definition according IEEE 802.3:1000BASE-T
or 100BASE-TX.
The following requirements apply to LAN wiring:
• Category 5 or better for 10/100 Ethernet
• Category 5e or better for Gigabit Ethernet
NOTE: The customer must take ISO / IEC 11801 requirements into account.
Warning
Connecting the device to a hospital network is creating a ME system according to IEC
60601-1. Brainlab recommends that the hospital network components are compliant with
an adequate IEC standard.
Network Precautions
Connecting the Buzz Navigation (Ceiling-Mounted) to a hospital network that includes other
equipment might result in previously unidentified risks to patients, operators or third parties.
The hospital should identify, analyze, evaluate and control risks arising by connecting the Buzz
Navigation (Ceiling-Mounted) to a hospital network.
Subsequent changes to the hospital network may introduce new risks and require additional
analysis. Changes to the hospital network include:
• Changes to the hospital network configuration
• Connecting additional items to the hospital network
• Disconnecting items from the hospital network
• Updating or upgrading equipment connected to the hospital network
It is recommended to use an adequate separation device for the network (LAN) interface with a
rating of minimum 1 MOOP and a dielectric strength of minimum 1.5 kV.
Only operate the equipment in secured networking environments. Make sure the network is
protected against unauthorized access (e.g., user authentication, firewall, etc.) and against
malicious software. If connected to an insecure network, the equipment functionality
cannot be guaranteed (e.g., due to possible malicious/non-secure software infections).
When integrating the Buzz Navigation (Ceiling-Mounted) into a wireless network, select an
adequate encryption (e.g., WPA2) to protect patient data from unauthorized access.
Network Information Flow
The intended information flow from the Buzz Navigation (Ceiling-Mounted) to the hospital network
and other devices in the hospital network is:
• Patient data transfer: Buzz Navigation (Ceiling-Mounted) receives data from a server inside
the hospital network of the hospital (e.g., PACS server)
• Remote access, Streaming or session sharing: the Buzz Navigation (Ceiling-Mounted) sends
data to a streaming client inside the hospital network of the hospital
Potential Hazards of Network Failure
The following hazardous situations could result if the hospital network or data coupling does not
meet the requirements listed in this section:
• Patient treated incorrectly due to:
78
- Network failure during patient data transfer
- Malware (e.g., viruses) causing PC to miscalculate data
