Compact Portable Backpack Pulse Flow1-5 Gear Medical Oxygen
Concentrator With 93+/-3% Purity For Asthma Therapy
Oxygen is a prescription drug in European and American countries
and Japan. According to different needs of users, doctors will give
appropriate prescription suggestions. Therefore, the quality of
oxygen (including oxygen concentration, pressure and flow), the
time of oxygen intake and the accuracy of oxygen flow are very
important for users' home health care and oxygen therapy.
What Is a Portable Oxygen Concentrator?
Portable oxygen concentrators are battery-operated devices that
provide supplemental oxygen to people who “require greater oxygen
concentrations than the levels of ambient air,” says Sanul
Corrielus, M.D., a board-certified cardiologist based in
Philadelphia. “Oxygen concentrators draw oxygen from your immediate
environment,” he adds, meaning they don’t require refillable oxygen
canisters or tanks, which makes maintenance and upkeep easy.
Pulse portable oxygen concentrator is to sense the user's breathing frequency through the chip and
sensor , so that the oxygen concentrator can adapt to the user's
breathing rhythm, control the oxygen flow, to provide users with
suitable for the user's needs of oxygen supply.
The traditional way of providing oxygen is to turn on the oxygen
and keep pumping it out whether the patient is breathing in or
breathing out.
Pulse type (on demand) Portable oxygen generators are different in
that, they provide oxygen only when they detect that the patient is
inhaling.
Pulse portable oxygen concentrator adopts high technical, pulse
oxygen supply is commonly used in portable oxygen making machine,
oxygen can be used 100%, when inhaling oxygen, such a benefit is to
save oxygen, more comfortable when intaking oxygen, unlike
continuous oxygen supply which has continual oxygen to the nasal
cavity.
The characteristics of pulse oxygen concentrator
Pulsed (also known as intermittent flow or on demand) POCs are the
smallest machines, usually weighing about 2.2 kg.
Because they are small and light, patients do not waste energy
gained from treatment by carrying them.
Their ability to conserve oxygen is key to keeping the device
compact without sacrificing oxygen supply time.
Most current POC systems provide oxygen on pulse (on demand)
delivery and are used in conjunction with nasal catheters to
deliver oxygen to the patient.
Main components and principles:
The POC operates on the same principle as a household oxygen
generator, using PSA technology.
The main components are small air compressor/molecular sieve
tank/oxygen storage tank and solenoid valve and pipeline.
Workflow: A circulating internal compressor compresses air through
a molecular sieve filter system
The filter is composed of silicate particles of zeolite, which
adsorb nitrogen molecules
The atmosphere is about 21% oxygen and 78% nitrogen; And 1% of the
other gas mixture
So the filtration process separates the nitrogen from the air and
concentrates the oxygen.
When the desired purity is achieved and the pressure of the first
molecular sieve tank reaches about 139Kpa
Oxygen and a small amount of other gases are released into the tank
When the pressure drops in the first cylinder, nitrogen is released
The valve closes and the gas is vented into the surrounding air.
Most of the oxygen produced is delivered to the patient and some is
sent back to the screen.
To wash away the residue in the nitrogen and prepare the zeolite
for the next cycle.
The POC system functions as a nitrogen scrubber that consistently
generates up to 90% of medical-grade oxygen.
Advantages compare with home oxygen concentrator:
Medical treatment allows patients to use oxygen therapy 24/7,
Compared with overnight use alone, the mortality was reduced by
about 1.94 times.
Helps improve endurance by allowing users to perform longer
sessions.
Helps increase endurance in daily activities.
Compare that to carrying around an oxygen tank
POC is a safer option because it provides purer gas on demand.
POC units are consistently smaller and lighter than tank systems
and can provide longer oxygen supplies.
Use at night
It is not recommended for patients with decreased oxygen saturation
due to sleep apnea, and a CPAP machine is usually recommended.
POC at night is a useful therapy for patients with desaturation due
to shallow breathing.
Especially with the advent of alerts and technology that can detect
slower breathing during sleep and adjust flow or push volume
accordingly.

Pressure Swing Adsorption Working Principle
First, air from the ambient atmosphere is compressed into
high-pressure air. This gas is then transferred into a vessel or
column which is filled with the adsorbent material (activated
carbon, zeolite, etc.). The selection of the adsorbent depends on
the gas to be extracted. This system is then pressurised and
depressurised cyclically, wherein the low sorbing gas will
gradually leave the column first, followed by the other gases.
There are four main phases of the pressure swing adsorption
process:
- Adsorption: The adsorber starts off pressurized with pure gas. The
impure gas is fed into the column which contains the adsorber.
Adsorption takes place and the pure gas is released from the top of
the column. This takes place until the adsorber has reached its
adsorption capacity.
- Depressurization: The adsorber is depressurized over in several
small steps to recover additional pure gas still in the adsorber.
Once all pure gas has been recovered, the desorbed impurities are
dumped into the PSA off-gas line.
- Regeneration: The adsorbent is purged with high-purity gas at
constant off-gas pressure to further regenerate the adsorbent bed.
- Repressurization: The adsorber is repressurized with pure gas and
is now ready to receive more feed gas to start the process over.
