One end be pressure relief opening pressure regulation valve port 36, pressure relief opening pressure regulation valve port 36 be equipped with can by the pressure relief opening pressure modulating opening 36 close or open
Pressure relief opening pressure-regulating valve diaphragm 37, pressure relief opening pressure-regulating valve diaphragm 37 are connected on the second iron core, similarly, when the second iron core is mobile,
Pressure relief opening switch valve film 37 moves, as shown in Fig. 2, when pressure relief opening switch valve film 37 is located at right end, by pressure release
Mouthful switch valve port 36 stops closing, is passed through the size of electric current in pressure relief opening switch valve electromagnet 35 when changing, and the second iron core and lets out
Press mouth pressure-regulating valve diaphragm 37 mobile, pressure relief opening switch valve port 36 is connected to the change of the openings of sizes in the first pipe portion 3-1.
Further, in order to realize continuously adjusting for pressure relief opening switch 36 opening degree of valve port, in pressure relief opening switch valve
It is additionally provided with the pressure release reset spring 38 of connection pressure relief opening pressure-regulating valve diaphragm 37, when pressure relief opening pressure-regulating valve diaphragm 37 is mobile by driving,
Overcome the elastic force of pressure release reset spring 38, the position steady and continuous variation of pressure relief opening pressure-regulating valve diaphragm 37, i.e., so that from pressure relief opening
The gas flow consecutive variations of 3-6 circulation control more accurate to realize continuously adjusting for respiratory resistance.
It should be understood that valve body can also be opened using other three-port structures, air inlet in some other embodiment
Other shapes structure can also be used by closing valve port and pressure relief opening pressure regulation valve port, for example, in air inlet switch valve port along air inlet side
To end air inlet pipe is set, several air inlets are circumferentially set in air inlet pipe, and air inlet, which switchs valve film, has certain thickness
Degree opens gas vent when air inlet switch valve film is mobile with respect to air inlet pipe gradually, thus increase sent from air inlet into
Tolerance.
First pipe portion 3-1, which has, is connected to the air inlet switch valve port 33 in breathing valve outlet 3-4, the first pipe portion 3-1
At pressure relief opening pressure regulation valve port 36, breathing valve outlet 3-4 is connected to patient's connector 8 by a gas outlet tube 39, works as trouble as a result,
When person's connector 8 needs to provide pressure of inspiration(Pi) or breath pressure to patient, by the shifting for controlling air inlet switch valve electromagnet 32
It is dynamic, can change from air inlet 3-5 be sent into pressed gas in breather valve number, pass through control pressure relief opening pressure regulator valve electromagnet 35
Movement, can change released from pressure relief opening 3-6 or into gas number, and then adjust breathing valve outlet 3-4 at, patient
Pressure of inspiration(Pi) and breath pressure.
Further, air inlet switch valve electromagnet 32 and pressure relief opening pressure regulator valve electromagnet 35 are by a breather valve closed loop
Controller 6 controls, 35 electricity of breather valve closed loop controller 6 and air inlet switch valve electromagnet 32 and pressure relief opening pressure regulator valve electromagnet

In some embodiments, flow sensor 4 and pressure sensor 5 can also be arranged using other mounting means, such as in addition
Collection tube is connect with gas outlet tube 39, as long as can be realized the flow and pressure information in accurate acquisition gas outlet tube 39,
It is not limited thereto.
Specifically, the input terminal of total processor 7 can obtain following data-signal in real time: pressure in gas outlet tube 39,
The blast pressure of flow, turbofan 2 in gas outlet tube 39 and the mode select signal of patient's input, total 7 basis of processor
The mode select signal of patient's input carries out corresponding calculation process to these data-signals, passes through 39 internal respiration gas of gas outlet tube
The changes in flow rate of body judges the respiratory state of patient, respectively to turbofan 2, air inlet switch valve electromagnet 32 and pressure relief opening
The output control signal of pressure regulator valve electromagnet 35, controls entire Breathing Suppotion equipment and forges by normal ventilation mode or different respiratory muscles
Mode operation is refined, respiratory muscle training mode includes expiratory resistance mode and inspiratory resistance mode.
As shown in figure 3, under normal ventilation mode, the input pressure gas into breather valve 3 of turbofan 2, the stream of patient
Amount change curve is obtained by flow sensor 4, and meets at total processor 7, and total processor 7 analyzes the variation tendency of data on flows,
For example flow first derivative or second dervative (unlimited, can also to replace algorithm using more respiratory triggering) judge the breathing of patient
State, so that output pressure variable signal and pressure change parameter, adjust 3 working condition of breather valve, to adjust intra-airway pressure
Or respiratory resistance.
Expiratory resistance exercise mode, also referred to as noninvasive ventilation treatment mode need to provide expiratory pressure by breathing valve outlet 3-4
Power, the at this time state of breather valve are as follows: the gas delivery port 23 of the air inlet 3-5 connection turbofan 2 of air inlet switch valve, air inlet
Mouth switch valve film 34 is under the promotion of air inlet switch valve electromagnet 32, air inlet switch valve mobile to right side shown in Fig. 2
Diaphragm 34 does not stop air inlet to switch valve port 33, at this point, by adjusting pressure relief opening pressure-regulating valve diaphragm 37 and pressure relief opening pressure regulation valve port
36 relative position changes the gas flow released from pressure relief opening 3-6, to adjust the output connecting with breathing valve outlet 3-4
Endotracheal pressure.
As shown in figure 4, turbofan 2 is sent into pressed gas, patient into breather valve 3 under expiratory resistance exercise mode
Flow curve is at OA sections, patient expiration, at this time by adjusting the opening degree of pressure relief opening pressure regulation valve port 36, can control to obtain
The exercise expiratory pressure needed.
Inspiratory resistance exercise mode needs to provide pressure of inspiration(Pi) by breathing valve outlet 3-4, at this time the state of breather valve are as follows:
Air inlet switchs valve film 34 under the promotion of air inlet switch valve electromagnet 32, mobile to left side shown in Fig. 2, and air inlet is opened
Closing valve film 34 stops air inlet to switch valve port 33, and turbofan 2 is not sent into gas into breather valve, at this point, being let out by adjusting
The relative position of mouth pressure-regulating valve diaphragm 37 and pressure relief opening pressure regulation valve port 36 is pressed, enters gas from pressure relief opening 3-6 when changing air-breathing
Resistance, to adjust the pressure of inspiration(Pi) in the gas outlet tube connecting with breathing valve outlet 3-4.
As shown in figure 5, turbofan 2 is not sent into pressed gas into breather valve 3, patient flow's curve is suffered from BC sections
Person's air-breathing adjusts the opening degree of pressure relief opening pressure regulator valve 36, that is, adjusts the resistance for entering gas from pressure relief opening 3-6, can control
The exercise pressure of inspiration(Pi) needed.
Under this expiratory resistance exercise mode and inspiratory resistance exercise mode, air inlet switchs valve port 33 and only opens and close
Two states are closed, and it should be understood that can also be adjusted by breather valve closed loop controller 6 under some other use demand
Its opening degree, it is flexible and convenient to use.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
