According to the protection time, oxygen self-rescuer can be 15
minutes, 30 minutes, 45 minutes, 60 minutes types. Compared to
other rescuers, compressed oxygen self-rescuer can be recycled,
which greatly reduced the cost.Compressed oxygen self-rescuer
provide the wearer with clean oxygen as pollution and toxic gases
or hypoxia occurred.
a, using a double-loop circulation breathing, that is breathing
from each unidirectional channel, compared with the reciprocating
breathing pattern, the advantage is resistance, no dust inhalation,
not choking, suction temperature is low, comfortable, safe and
b, Oxygen has three methods: quantitative oxygen, automatic and
manual oxygen supply oxygen supply. Greatly improving the safety
and reliability of respiratory protection.
c, filling oxygen absorber replacement, easy maintenance and
d, protection for a long time, easy to self-help.
e, small size, light weight, easy to carry.
f, can be used repeatedly, the use of low cost.
g, pressure indicators observed to Off, and easy to use.
When uses the oxygen self-rescuer, the cylinder valve
counter-clockwise rotation, high-pressure oxygen from the oxygen
cylinder pressure through the valve to ≥ 1.2L/min enter airbags,
hands off the plate, oxygen nourishing stopped. When the negative
pressure in the respiratory system, the platen inward contraction,
oppression pressure lever to open the body to ≥ 60L/min oxygen
filled balloon and the air bag inflates, air nourishing pole plate
away, oxygen nourishing stopped. If the pressure in the respiratory
system and the exhaust valve than the discharge pressure, the gas
from the exhaust valve overflow. Inhale, oxygen in the air bag has
to enter the body through the mouth. Exhale, exhale through the
hose into the clean gas tank, gas carbon dioxide chant placed in
the clean tank CO2 absorbent, and the remaining gas into the
airbag, according to a breathing cycle.
