Instructions for use – Infinity Acute Care System – Monitoring Applications VG6.n
– The LAN-based IT-network uses TCP/IP
communication protocols. It must be capable of
supporting either unicast (static or dynamic
addressing requiring ARP or RARP), as well as
multicast and broadcast transmissions. It needs
to allow the use of the Internet Group
Management Protocol (IGMP version 2).
Dräger medical devices send out data packets
on the IT network. Dräger products like
CentralStation monitors, Gateways, or other
bedside monitors, which are configured to
receive these data packets, use the Internet
Management Protocol to join or leave an IP
Multicast group. An example of this data flow is
bedside devices sending out their patient data
using IP multicasting. A CentralStation monitor
can join into each multicast channel to capture
and display bedside patient data information.
– Dräger devices may also require that the IT-
network provides support for three dedicated,
independent virtual local area network (VLAN)
connections for bedside medical devices,
mobile patient monitors, and for access to the
Health Delivery Organization (HDO) clinical
network. Additional information can be obtained
from your DrägerService representative.
– Besides direct network connections, other
possible communication interfaces include:
Serial data connections, conforming to EIA
RS-232 (CCITT V.24/V.28) for MEDIBUS-
based products, paging interfaces, and
connections to 3rd party medical devices.
IEEE 1073 conformant interfaces (Medical
Information Bus) for connections to 3rd
party medical devices (IEEE 1073.3.2 or
1073.3.1 and 1073.4.1).
Serial data connections, conforming to USB
2.0, for human interface devices (mouse,
keyboards, mass storage devices such as
flash disks, CD drives, etc.).
–
Security
for Dräger wireless products is
implemented using the Advanced Encryption
Standard (AES) WPA2, with pre-share key
administration at the time of installation.
Security for selected Dräger clinical IT products
includes SSL and additional capabilities defined
in the Medical Device Disclosure for Medical
Device Security (MDS2) form.
– There are potential hazardous situations that
can result from the failure of the IT-Networks to
provide the characteristics required to meet the
purpose of the medical device connection to the
IT Network. Dräger products will attempt to
detect and mitigate these potentially hazardous
situations. Related to this medical device, these
situations may include:
Untimely delivery of data (alarm
annunciation/parameter values
exchange/etc.), depending on a “reliable
distributed alarm system or not”
Data not sent or sent to the wrong device
Missing data
Patient data intercepted/corrupted
Incorrect time stamp on data
Alarms not detectable in time due to unsafe
distributed alarm system or alarm present at
network interruption
Alarm pause/audio pause reset due to
network interruption
Data privacy lost due to missing
firewall/virus protection
Wrong equipment settings/wrong or no
alarms due to missing firewall/virus
protection
