Chapter 4. THEORY OF OPERATION
This section describes the theory of operation for the EverFlo Oxygen Concentrator.
4.1 PNEUMATIC OPERATION
Refer to Figure 4-1 while reading the following discussion.
The room air is drawn into the unit through the air inlet filter by the compressor. The compressed air is routed to
the sieve beds through an electronically controlled Solenoid Valve Assembly. The Solenoid Valve alternates the
airflow to a pair of sieve beds that allows Oxygen production. The Solenoid Valve Assembly also alternates the
flow through the sieve beds to allow purging of the Nitrogen molecules from the sieve beds.
At startup, the valve/sol eno id is de-energized allowing compressed air to flow through both sieve beds until the
pressure sensor builds up to switching pressure. At switching pressure, a 12-volt signal is received at the
valve/solenoid closing off the input and allowing the compressed air to cycle through one of the sieve beds. As
the air is cycled through one of the sieve beds, the molecular sieve material traps the Nitrogen molecules from
the air and allows the Oxygen enriched air to flow through the sieve bed.
At 5 liters of flow, approximately 1/3 of the Oxygen enriched air enters the product tank and the other 2/3 of the
Oxygen enriched air is passed through an orifice in the sieve bed to purge the trapped Nitrogen molecules from
the sieve bed, allowing the sieve material to be ready for Oxygen production during the next cycle.
The concentrated Oxygen is stored in the product tank. The product tank is continuously filled with concentrated
Oxygen and the output from the product tank is regulated at 5.5 psig nominal. The product tank pressure is
continuously monitored using a pressure sensor. The stored Oxygen is delivered to the patient through a
pressure regulator, an externally adjustable flow meter and a microbial filter.
In the beginning, the 230V units, had an orifice built into the purge valve. The
electronically controlled purge valve controls the Oxygen flow timing from one sieve
bed to the other based on the flow meter setting.

4.2 ELECTRICAL OPERATION
The EverFlo Concentrator is a medical device, which produces concentrated oxygen from room air for delivery to
a patient. It uses a molecular sieve and a pressure swing adsorption process to concentrate oxygen from air. The
device consists of filters, a compressor, a sieve canister module, a set of valves, a microprocessor-based
electronic controller PCA, a flow meter and a cooling fan – all contained within a plastic enclosure.
The EverFlo Embedded Software
valves used to generate the oxygen, measures/monitors the pressure & oxygen levels, drives the Elapsed Time
counter (Hour meter), reports exception conditions to the User via visual and audible indicators and provides
diagnostic information to a Host computer via an RS232 communications interface.
—via the microprocessor contained on the PCA Controller—controls the sieve
4.3 PCA CONTROLLER OVERVIEW
All the electric / electronic functions of the EverFlo Concentrator reside on the PCA Controller. A block diagram of
the PCA controller is provided in Figure A. The reader is urged to continually refer to this diagram when reading
the remaining sections of this document.
The PCA controller can be sub-divided into 2 major sections:
1.
Power distribution and DC voltage generation.
2.
Monitoring / Control / User Interface.
Page 12 E
Figure 4-2: EverFlo PCA Controller Block Diagram
VERFLO
TM
SERVICE & TECHNICAL INFORMATION 1039055, VER. 06
4.3.1 POWER
The AC mains power, via the line cord, is brought onto the PCA and the “switched” AC is distributed to the
Compressor, the Cooling Fan and to the AC to DC conversion module. The DC voltages that are generated are
used to power the remaining circuitry.
The PCA contains a 1 Farad “super capacitor” which is used to sound the Audible Indicator when the AC mains
power is absent AND the mains switch is in the ON position. The purpose is to alert the User to the fact that
there has been a loss of AC mains power (that is, an AC mains power failure, a plug removal, a blown fuse). The
circuitry functions as follows:
1.
During normal operation, the capacitor is energized (charged) using the +5 VDC. The capacitor
reaches full charge after approximately ½ hour of system on-time.
2.
The mains switch has a 2nd set of contacts that are used to determine whether the switch is open
or closed. If the switch is closed (in the ON position) and the microprocessor is not functional (no
DC power), then the backup circuitry is such that it will turn on the Audible Indicator, using the
“super cap” as its energy source.
The “super cap” is capable of sounding the Audible Indicator for a period of greater than 8 minutes, given that it
is fully charged.
4.3.2 MICROPROCESSOR AND ASSOCIATED CIRCUITRY
The remainder of the PCA controller electronics is centered around the MSP430F155 microprocessor. The
microprocessor is the only processing element contained in the EverFlo concentrator. In addition to the
microprocessor, the “remaining circuitry” consists of sensors, LEDS, a piezo Audible Indicator, amplifiers / signal
conditioners, communication buffers and discrete components.
The embedded software, in conjunction with the microprocessor and its associated hardware, is used to control
the sieve valves, measure/monitor the pressure & oxygen levels, control the oxygen sensor, drive the Hour
meter, reports exception conditions to the User via visual and audible indicators and provide diagnostic
information to a Host computer via an RS232 communications interface.

The system pressure test is used to verify the proper operation of the EverFlo Compressor and Sieve Canister
Assemblies.
If pressures are not within the normal operating pressure, it does not necessarily indicate an issue
with the concentrator. T he F ina l Test located in the Testing Chapter of this manual is the only test
to be used when deter mining a k nown good E verFlo Concentrator from a Concentrator requir ing
repair.
1.
Run the unit with the front and rear cabinets in place for a minimum of ten minutes.
2.
Set the flow to 5 LPM (1 LPM for units equipped with pediatric flow meters).
3.
Turn off the Everflo Oxygen Concentrator.
4.
Remove the front and rear cabinets from the unit.
5.
Disconnect the yello w pressure tubing from the f itting on th e PCA. Using the pres s ur e gau ge, “T”
fitting, and pressure tubing supplied with the Concentrator tool kit, connect to the Pressure
Regulator as shown below.
6.
Turn the unit on and allow the unit to cycle for at least two (2) minutes to stabilize.
7.
Hold the pressure gauge in a vertical position.
8.
Verify press ures a gains t the tab le below. This table is a ref erence gui deli ne for s ystem press ures
and troubleshooting. If a value is measured outside of these ranges, it may not mean the unit has
a fault. If the Outlet Pressu re and Out let Oxygen values are w ithin tolera nces, and the u nit is not
alarming, the unit should be considered acceptable.

Вопросы и ответы покупателей
-
Ответ администратораДа, вы можете использовать автомобильный инвертор. Обратите внимание — лучше приобретать инвертор 1000 Вт и подключать его напрямую к акб автомобиля, Т.к предохранители и проводка прикуривателя может не выдержать нагрузки.
-
Ответ администратораПрибор производится в США
-
Ответ администратораEverflo используется с канюлями или маской — на выбор. Также, концентратор можно подключать к ИВЛ аппарату. Прибор имеет постоянный поток — подходит для приготовления кислородных коктейлей, для этого вам понадобиться специальный шейкер и смесь для образования пены (имеются в продаже). Для подбора комплекта оборудования, позвоните нам или пришлите запрос на почту info@medpribor.pro
-
Ответ администратораШланг с резьбой для подключения увлажнителя находиться внутри концентратора в отсеке с фильтром тонкой очистки. Отсоедините защитный кожух на задней стенке концентратора — там вы увидите фильтр и шланг.
-
Ответ администратораДа, вы можете использовать любую дистиллированную воду. Дешевле всего ее приобрести в магазине авто-запчастей.
-
Ответ администратораВо-первых это единственный кислородный концентратор способный работать круглосуточно. У него есть специальный разьем для крепления и подключения станции наполнения кислородных баллонов.
Во-вторых — цена для торгующих организаций гораздо интереснее чем на филипс.
