How The Eclipse 2 Works

14
Introduction
The Eclipse 2, Personal Ambulatory Oxygen System with AutoSat Technology is a portable medical
device used to extract oxygen from the atmosphere, concentrate it to greater than 90% and present it to
the patient. The device will operate in continuous flow or Pulse Flow Modes. In Continuous Flow Mode
the oxygen is provided at a constant flow rate between 0.5 and 3.0 LPM. In Pulse Flow Mode, oxygen is
supplied in a bolus at the beginning of each inspiration, providing a selectable range setting of flow
between 1.0 and 6.0. A setting of 1 in Pulse Flow Mode delivers the equivalent amount of oxygen
(FIO2) as a Continuous Flow Mode setting of 3 LPM.
The Eclipse operates from either external power or from an internal rechargeable Power Cartridge. The
system includes a “Smart Battery” charger that recharges the internal Power Cartridge whenever the
Eclipse is connected to external power. The system monitors and controls both the power source and
the Power Cartridge charger.
ATF® Concentrator Module
The Eclipse uses a passive system to separate oxygen from air. Air flows into the Eclipse where it is
filtered and then enters the compressor. Pressurized air flows from the compressor into the ATF®
Concentrator Module where it is separated into oxygen and nitrogen components. The air separation
process uses a rotary valve system to force air through a series of pressurized sieve beds. Through a
process known as “pressure swing adsorption,” nitrogen molecules are collected on an adsorbent
material allowing the concentrated oxygen to be forced through a sieve bed into the product tank. The
nitrogen molecules are then purged from the adsorbent material using a vacuum pressure cycle.
Oxygen flows from the product tank through a HEPA filter and past a sensor that measures flow and
concentration. A flow control valve regulates the flow of concentrated oxygen presented to the patient.
The process is continuously repeated during operation.

15
Compressor and Compressor Enclosure
The Eclipse compressor is a two-cylinder, variable speed wobble piston compressor, driven by a highly
efficient Brushless DC (BLDC) motor. When air flows into the compressor enclosure, it passes through
an air intake filter/muffler that muffles sound and filters out impurities. Using one cylinder, the
compressor takes in filtered air and delivers it to the ATF Module under pressure. The second cylinder
draws a vacuum on the ATF module and exhausts nitrogen rich gas to the exhaust vent.
Using a multifaceted approach, sound, heat, and vibration generated by the compressor are mitigated by
the compressor enclosure. Vibration and structure-borne noise are addressed by the dual axis gimbal
that supports the compressor and the tubing that connects the compressor to the ATF module. The rigid
walls of the compressor enclosure and the sound adsorbing foam that lines it diminish the radiated noise.
The centrifugal blower mounted within the compressor enclosure serves to efficiently draw cooling air in
over the compressor cylinders while simultaneously pushing exhaust gas out of the concentrator.
Power Distribution
The Power Manager takes external power that comes into the Eclipse from the power supplies or Power
Cartridge and monitors and controls power distribution to the rest of the Eclipse system. The Power
Manager drives the compressor, ATF module motor, blower, and provides power to the control module.
In addition, when the unit is connected to an external power source, the power manager monitors and
controls the recharging of the Power Cartridge.
Control Module
The control module is at the center of nearly all Eclipse functions. The module constantly monitors
dynamics such as temperatures, pressures, product flow and concentration, and user input. It
determines proper compressor and ATF motor speeds needed in order to provide optimum system
performance. In addition, this system supports the operation of the Control Panel and its indicators.
The Control Module utilizes a proprietary ultrasonic flow and concentration sensor and a flow control
valve to accurately control the flow of oxygen in Continuous and Pulse Flow Modes.
Figure 2: Flow Sensor Diagram

16
Control Panel
The control panel provides a user interface consisting of a membrane panel keyboard, Liquid Crystal
Display (LCD), external power present indicator, Power Cartridge capacity indicator, alarm status
indicators, and an audio transducer. The user interface informs the user of the system status and allows
the user to set the desired flow rate and flow mode.
Figure 3

18
Continuous Flow Mode
The user may set the Eclipse oxygen flow rate and mode. Continuous Flow Mode delivers a constant
flow of oxygen to a patient by means of tubing and a nasal cannula at rates between 0.5 LPM and 3.0
LPM. Within the Eclipse, concentrated oxygen is stored in a 500ml product tank at pressures in the
range of 5 to 9 psi. This pressure gives Continuous Flow Mode the capability to deliver the indicated flow
rate to the patient even if extension tubing is used, up to 50 feet long. In addition, the Eclipse
Continuous Flow Mode is fully compatible with humidifier use.
Pulse Flow Mode
The Eclipse Pulse Flow Mode delivers a high flow of oxygen at the very beginning of each inspiration.
The approach is based on the manner in which gas is absorbed into a patient’s airway. Eclipse users
may select pulse volume delivery rates at settings between 1 and 6. Regardless of setting, the pulse
profile is a simple square-wave pulse based on a 16-ml/liter volume. (Refer to “Pulse Profiles” table
below). Pulse durations are no less than 100 milli-seconds. Pulse durations do not exceed 450 milli-
seconds due to dead space considerations.

Table 1: Pulse Profiles
The fundamental approach to triggering and controlling the oxygen bolus in Pulse Flow mode is as
follows:
The user may select a pulse trigger sensitivity in settings ranging from 1 to 6. The pulse will be triggered
when the system meets all of the following criteria:
•The cannula pressure has dropped below the trigger point (typically between 0.15 and 0.45
cmH20)
•At least 1¼ seconds has passed since the last pulse began

19
Provider Mode Functions
Providers can access provider mode software functions using the control panel. All provider mode
information is displayed on the LCD. The software shall advance the following display mode when the
“No Smoking” icon is pressed:
1. Alarm Code (AC)
2. Hours of Operation (H)
3. 9-volt Battery Status (9V)
4. Software Version (SW)
5. Pulse Sensitivity (PS)
6. LCD Contrast (CT)
Alarm Code
While in Continuous Flow Mode, pressing the “No Smoking” icon displays the current Eclipse alarm code
on the LCD. This code may be used to help diagnose conditions indicated by the alert and alarm
indicators. The LCD will show “AC=”. Refer to the “Provider Maintenance” section for further
information.
Hours of Operation
The Eclipse hour meter provides valuable information on hours of operation. Providers may display the
total number of hours of operation using the control panel. The display counts up to “99,999.9” hours,
then rolls over to “00000.” The LCD will show “H=”. Refer to the “Provider Maintenance” section for
further information.
9-Volt Battery Status
The status of the 9-Volt Battery is provided. This is the actual voltage of the 9-Volt battery. The LCD will
show “9V=”.
Software Version
Providers may occasionally need to obtain the software version on the Eclipse to perform maintenance.
The provider may display software version numbers for both the Control System and the Power Manager
software using the control panel. Refer to the “Provider Maintenance” section for further information.
Pulse Mode Sensitivity Adjustment
During patient setup, a qualified clinician may adjust the Pulse Mode sensitivity to best suit patient
inspiratory effort. The LCD will show “PS=”.
LCD Contrast
Providers may need to adjust the LCD contrast. The contrast may be set from O to 10, with 10 being
the highest contrast. The LCD will show “CT=”.

20
Service Mode Functions
Factory maintenance or service updates may sometimes be required on the Eclipse. Factory and
qualified factory-trained technicians can access service mode software functions by using the Service
Port located on the back of the unit. The Service Port is not for patient use.
