The working principle of breather valve 3 are as follows: spacing between first 34 adjusting knob of turning knob and upper spring sliding block 301, when two
When person's spacing reduces, spring is extruded between the two, so that the spring is more difficult to be deformed.At this point, respiratory pressure valve film 30
In upper vent, and 30 outer diameter of respiratory pressure valve film is matched with upper vent internal diameter, and respiratory pressure valve film 30 seals upper vent
It is stifled；
Breather valve 3 is additionally provided with pressure inductor, can monitor 3 pressure of breather valve, and pressure inductor is specific breather valve 3
Set-up mode is well-known technique.
From exhalation 31 air inlet of lid, which upwards pressure to respiratory pressure valve film 30, when the power of the air pressure makes
When holding spring and being extruded, respiratory pressure valve film 30 is moved up along limited post 320, is left when respiratory pressure valve film 30 is moved to
When upper vent, gas from valve body 32 is left between the two, so that pressure in valve body 32 be reduced；
At this point, respiratory pressure valve film 30 is held under spring is pressed down against effect upper, respiratory pressure valve film 30 is come back to
In blow vent, upper vent is blocked；In conjunction with Fig. 4, when knob 34 moves down, then to hold spring and more squeezed, then
Respiratory pressure valve film 30 receives bigger downward power, at this point, the gas that exhalation lid 31 enters needs bigger pressure could will
Respiratory pressure valve film 30 jacks up；Conversely, the air pressure that respiratory pressure valve film 30 is jacked up needs is smaller；
Upper spring sliding block 301 and lower spring block 302 are used to abut holds spring above and below；When knob 34 rotates, above and below
Holding spring may also rotate with it, and spring directly will not apply radial power to respiratory pressure valve film 30 at this time, avoid breathing
The loss of pressure valve film 30.
The lid 10 is additionally provided with pressure limiting valve 17, explosion-proof valve；The humidification bottle 1 is additionally provided with pressure gauge, while pressure sensing
Device is also communicated with pressure gauge, monitors pressure value in pressure gauge.
The respirator is respiration nose stopper, nose cup or breathing intubation.
A kind of working method of the utility model are as follows:
Gas source air and oxygen enter from two gas source interfaces 22 respectively, adjust flow by two flow control valves 25,
Two gas source interfaces 22 can be controlled by atomization mixing switching valve 26 to communicate with mixing chamber or atomization gas delivery outlet 24 respectively；
When atomization mixing switching valve 26 switches to mixing chamber, the gas of gas source interface 22 is into such as mixing chamber；When atomization is mixed
When conjunction switching valve 26 switches to atomization gas delivery outlet 24, the gas of gas source interface 22 enters atomization gas delivery outlet 24；
Such as: output gas total flow 11L/min exports oxygen concentration 50%.Then pass through calculating: 50%=(0.21Vair+
VO2)/(Vair+VO2), Vair+VO2=8L/min is obtained；Oxygen: 4L/min, air 7L/min.Two flowmeters carry out not as needed
It is exported with gas flow；
It is to mix switching valve by atomization that whether gas enters atomization delivery outlet with mixing chamber is entered by flow control valve out
26 decisions；Being atomized switching valve can be the valve body for being radially provided with a through-hole, be well-known technique, when needing to be atomized by one
Atomization mixing switching valve 26 is transformed into atomization shelves, and gas enters atomizer 13 by nebulization channel, another atomization mixing switching valve
26 switch to mixing chamber, carry out unilateral gas atomization, and the gas of two gas source interfaces 22 respectively enters mixing chamber and a mist at this time
Change gas delivery port 24, is mixed in humidification bottle 1 after being atomized well with another gas come out by mixing chamber, complete unilateral mist
Change mixing；When two atomization mixing switching valves 26 switch to mixing chamber ventilation, the gas of two gas source interfaces 22 enters mixed
Chamber is closed to be mixed；When two atomization mixing switching valves 26, which are switched to, to be communicated with atomization gas delivery outlet 24, two gas source interfaces
22 gas passes through atomization gas delivery outlet 24 and enters in humidification bottle 1.
Switch to mix shelves if not needing atomization, two gases enter humidifying pipe 14 after mixing chamber mixes, through gurgling
Through breathing delivery outlet output after simple humidifying.Both sides can be atomized mixing switching valve simultaneously if you need to increase output gas humidifying degree
26 conversion shelves are all transformed into atomization shelves, carry out bilateral atomization, and two kinds of gases after atomization is good are mixed in humidification bottle 1, mixed
High humidity gas after good is exported through pneumostome.
Gas enters mixed gas air inlet 11 from mixed gas delivery outlet 23, downwards then along humidifying pipe 14, due to
14 lower end of humidifying pipe there is not Yu Shuizhong, so that the gas come out from humidifying pipe 14 is through the simple humidifying of gurgling；
The atomization mixing switching valve 26 of mixer 2 is opened, and corresponding gas can also pass through gas from atomization gas delivery outlet 24
Pipe enters atomization port 12, then by atomizer 13 by water atomization in bottle body, to the humidification in humidification bottle 1；
Patient is supplied oxygen from breathing port 18 by the gas of humidification.Due to the respiration of human body, exhale in people
When, the exhaust gas of exhalation leaves whole device from the breather valve of breathing tube end.
Below it is some comparative tests of the utility model:
Two-flow atomizing mixer and market sky oxygen mixer output gas humidity contrast table
Two-flow atomizing mixer is the usage mode that the utility model is not turned on heating function；Two-flow atomization heating is mixed
Clutch is the usage mode that the utility model opens heating function.
