Hospital Network

General Information
Users must identify, analyze, evaluate and control the risks that may occur when connecting the
Curve system to a network or data coupling where other equipment is connected.
Making changes to the network/data coupling could introduce new risks that require additional
analysis. These changes may include, but are not limited to:
• Changes in configuration
• Connection or disconnection of additional equipment
• Update or upgrade of connected equipment

Safety
Network Precautions
When integrating the Curve system into a wireless hospital network, select an adequate
encryption (e.g., WPA2) to protect patient data from unauthorized access.
Streaming the display content of the Curve system or using session sharing may create
high traffic load on the hospital network.
Potential Hazards of Network Failure
The following hazardous situations could result if the hospital network or data coupling does not
meet the requirements listed above:
• Patient treated incorrectly due to:
• Unwanted exposure of the patient to anesthetics or radiation due to:
Technical User Guide Rev. 1.1 Curve Dual Navigation Station Ver. 1.2
Value
• Minimum: 2 Mbit/s (e.g., for patient data transfer)
• Recommended: 10-50 Mbit/s (e.g., for streaming and remote access)
• Optimum: 100 Mbit/s - 1Gbit/s (e.g., for session sharing)
• Minimum: ≤ 100 ms
• Recommended: ≤ 25 ms
• Optimum: ≤ 2 ms
• Only connect equipment to a secured network
• Network protected against unwanted access (e.g., user authentication,
firewall, etc.)
• Network protected against malicious software
• Secured wireless network
- Hacked WLAN connection
- Malware (e.g., viruses) causing PC to miscalculate data
- Inability to transfer patient data to the equipment due to latency from a high number of
wireless devices in same frequency range (e.g., 2.4 GHz / 5 GHz)
- Network failure during patient data transfer
