Kangaroo™ Connect Enteral Feeding Pump | 4

Wireless Features
The wireless feature of the Kangaroo Connect pump is initially disabled unless
activated by a specific type of feeding set. Through the use of a wireless enabled
Kangaroo Connect pump and a communications hub, clinicians will be provided
with the ability to acquire and display nutritional delivery data from the pump
within a website called the Kangaroo Connect Portal.
The wireless technology used within the Kangaroo Connect pump and
communications hub is built on the IEEE 802.15.4 standard which transmits in
the ISM band (2.4GHz). A patented combination of short range and long range
wireless provides seamless wireless capability for the pump.
The following are required in order to utilize the wireless capability of the
Kangaroo Connect Pump:
1. Kangaroo Connect pump with short range wireless chip (located in but
initially disabled in ALL Kangaroo Connect pumps)
2. Either a:
• Kangaroo Connect wireless communication hub (WCH) with 3G wireless
capability, or
• Kangaroo Connect WiFi/Ethernet communications module (WiFi
module) with WiFi/Ethernet capability
3. Kangaroo Connect ENtelliSet Feeding Set (designed to enable the short
range wireless chip in the pump when loaded in the pump)
4. Internet access
Wireless Quality of Service
The wireless communication feature of the Kangaroo Connect pump was
designed to add multiple features and benefits without compromising pump
safety. In the event of an intermittent or failed wireless connection, the pump
feeding operation is designed to work independently of any wireless connection
and will continue to operate normally and safely. Therefore, the patient can be
confident their pump will continue to work properly even if there is a wireless
delay, loss of signal, or wireless failure. The communication system is designed
to take advantage of the time when a connection is available and wait for a
connection to be restored when it is not. The pump will store data for up to 30
days, for upload when a connection is available. As the pump is designed to be
ambulatory, loss of wireless capability is expected to be a common occurrence.
The Kangaroo Connect pump wireless system has an acceptable latency of 25
seconds for message exchanges. (Typical latency is approximately 5 seconds.)
However, this latency is not a concern because the data is not being used in
real time. Since the pump confirms that all transmitted data is received by the
Kangaroo Connect Portal before it is deleted, any data not acknowledged will
be resent at a later time within the 30 day window. Considering the acceptable
latency and a low signal priority on the network, the following table shows the
network access time required by the pump to prevent any loss of stored data
based on the probability of network data loss:
Probability of Network Data Loss Network Access Time Required (Hours)
Probability of Network Data Loss Network Access Time Required (Hours)
0% 6.3
10% 6.9
20% 7.8
30% 8.9
40% 10.4
50% 12.5
60% 15.6
70% 20.8
80% 31.3
90% 62.5
Wireless Safety
The following pump features were specifically designed
to ensure patient safety related to use of the wireless
communication feature:
1. The pump only provides alarms directly from the
pump to a user/ clinician. The pump does not provide
real time communication of alarms though the
wireless communications feature, but rather logs
historical alarm events. This prevents confusion as to
how the pump alarms (only through the pump itself)
and prevents the condition where loss of wireless
connection could cause a missed alarm.
2. The pump is designed to operate independently of any
wireless communications, allowing it to continue to
provide safe and effective enteral nutrition to a patient.
Therefore, the patient can be confident their pump will
continue to work properly even if there is a wireless
delay, loss of signal or wireless failure.
3. The wireless data communicated by the pump is
encrypted for patient security and protection. No
confidential patient information is communicated
from the pump to internet, so privacy remains intact
and secure.
4. With medical device hacking being a heightened
concern, this pump has been designed from the
ground up to prevent wireless intrusions seen on older
medical devices. This pump was tested to the latest
standard of penetration testing to help safeguard
against possible intrusions.
System Configuration / Operation
No additional system configuration is required to operate
the wireless communication feature. Refer to Section 5 –
System Setup for instructions on how to install the WCH or
WiFi module.
Operating Distances and Ranges
For the wireless capability to work properly, the pump must
be within 300 feet of the WCH or WiFi module with direct
line of sight. Obstructions such as walls and doors will
reduce this range. Strength of the wireless signal between
the pump and WCH or WiFi module can be determined by
looking at the wireless icon on the pump screen.
Wireless Coexistence
Wireless coexistence testing has been performed on the
wireless communication feature of the Kangaroo Connect
pump. Testing established on the intended environment
included multiple sources of possible interference such as
Wi-Fi connections, Bluetooth devices, cellular connections,
cordless phones, and microwaves, with no degradation
of signal noted. Should a coexistence issue be suspected,
turn off or relocate any other electronic devices located
near the pump or WCH or WiFi module which might
generate interference.
