At present, lung ventilator has the function that flowing gas in corrugated hose (such as air) is humidified and pressurizeed.Exhale
Suction machine is internally provided with heater, and heater to the water (or other aqueous solution) in water pot by constantly heating
Afterwards, gas, which flows through the water surface, will become moistening, while being heated to gas, thus being brought for user more comfortably makes
With experience.It is additionally provided with blower fan inside lung ventilator, extraneous gas can be drawn into inside lung ventilator and while can be with by blower fan
Certain pressure is applied to the gas entered in corrugated hose, so contributes to further enhance using effect.Go out in user
When now breathing is stagnated, blower fan can further raise the pressure into the gas of breathing machine pipeline by increasing rotating speed
Power, to maintain the gas exchanges between user and lung ventilator, it is ensured that still maintaining just when breathing is stagnated occurs in user
Normal gaseous metabolism.
When the heater in lung ventilator is heated, rated power is generally kept in tens watts (such as 30W), so
It can ensure that the evaporation rate of moisture is maintained near a steady state value so that the gas in breathing machine pipeline is maintained at a conjunction
Near suitable humidity, usage experience reaches most preferably.Too high power may be such that the evaporation rate of moisture is too fast, cause breathing
Gas in machine pipeline, which is excessively moistened, or gas temperature is too high causes patient to be in dangerous situation, and usage experience is deteriorated.It is too low
Power then may be such that the evaporation rate of moisture is too low, cause gas in breathing machine pipeline excessively to be dried or gas temperature
It is too low, equally also usage experience can be deteriorated.

Order performs shown or described step.
Solve lung ventilator inner heating device and blower fan has to rely on large power supply when meeting job requirement and powered
Problem, the present inventor passes through in-depth study, has searched out the rational technique scheme that can be solved the above problems.Because
The course of work that blower fan moment accelerates typically all maintains shorter, in a period of this is shorter, even if stopping to the wet of gas
Degree, which is adjusted, will not also produce more obvious change there is provided the humidity of the gas to user.Even if moreover, being user
The humidity of the gas of offer can produce certain change, and the gas relative to moistening is the comfortable experience that brings of user, far not
Blower fan can be offset can not accelerate brought potential risk in the acceleration.
Therefore, in the demand that blower fan has moment to accelerate, more inessential is just become to the demand that water is heated.Based on this
Analysis, can accelerate both demands to carry out Time-sharing control heating and blower fan, can temporarily be controlled when accelerating demand there is blower fan
Refrigerating/heating apparatus stops the power of heating or reduction heater, resumes work again after blower fan completes acceleration demand.
In the Poewr control method of the lung ventilator of the embodiment of the present invention, the lung ventilator includes power supply, heater and wind
Machine.As shown in figure 1, the Poewr control method of the lung ventilator of the embodiment of the present invention, mainly comprises the following steps.
Step S110, power supply is powered for heater and blower fan simultaneously when, monitors the instantaneous work(during blower fan operation in real time
Rate.
Step S120, compares the instantaneous power of blower fan and the size of the first predetermined power in real time, if the instantaneous work(of blower fan
Rate is more than or equal to the first predetermined power, then goes to step S130, otherwise go to step S140.Wherein, the first predetermined power quilt
It is preset as recognizing whether blower fan enters the working condition instantaneously accelerated.If the instantaneous power for real-time monitoring blower fan exceedes
First predetermined power, then illustrate that blower fan just enters the working condition instantaneously accelerated.Generally, the appearance of such case be for
The pressure value of the gas in breathing machine pipeline is improved, thinks that the user of lung ventilator maintains normal gas exchanges, it is to avoid make
There are the situations such as apnea in user.
Step S130, when the instantaneous power for comparing blowing machine is more than or equal to first predetermined power, reduction heating
The instantaneous power of device, such as, the second power is reduced to by heater from previous a certain power.Now, heater is produced
Raw heat will decline.Heat produced by heater declines, and only can somewhat change by water pot to a certain extent
Other moistening degree, will not significantly affect the use feeling of user.
Step S140, when the instantaneous power for not comparing blowing machine is more than or equal to first predetermined power, explanation
The power and job state for maintaining blower fan previous, it is not necessary to reduce the instantaneous power of heater, maintain heater to work as
Preceding heating-up temperature and power output.
For the instantaneous acceleration of blower fan short time, heater suitably reduces working power or directly stops heating, warp
The moistening degree for crossing the gas of water pot also only has human body slight change inconspicuous, and this slight change is unlikely to substantially to change
Become the impression that user moistens degree to gas, also do not interfere with the using effect that user uses lung ventilator.Therefore, it is of the invention
Embodiment, when blower fan instantaneously accelerates, actively reduce the instantaneous power of heater, do not changing user's usage experience
In the case of, it is possible to prevente effectively from the events such as apnea occurs in user, the security function of lung ventilator is improved, while also reducing
The high power requirement of power supply in lung ventilator, the power of power supply need not meet instantaneous acceleration and the heater of blower fan simultaneously
Normal heating.So as to reduce the requirement in terms of power compared with prior art so that slightly low power power supply also can
The work of blower fan and heater in competent lung ventilator, it is only necessary to which the power of power supply can match the instantaneous acceleration demand of blower fan
And demand when heater and the equal normal work of blower fan (work of non-momentary boost phase), it is not necessary to can simultaneously
The normal operation of instantaneous acceleration and heater with extension set.Moreover, it is contemplated that typically also being got over to the smaller power volume of power
It is small, therefore embodiments of the invention also reduce the volume of power supply in lung ventilator, so as to be beaten for the further miniaturization of lung ventilator
Good basis down.
In embodiments of the invention, when blower fan instantaneously accelerates to maintain the normal gas exchanges of user to be used to avoid
Person occurs after the situations such as apnea, and the instantaneous power of blower fan can lower again, it is to avoid provide pressure for a long time for user
