Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art under not making creative work premise, the every other embodiment obtained, broadly fall into scope.
The core of the present invention is to provide and a kind of controls the method for respirator humidity, Apparatus and system.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the flow chart of a kind of method controlling respirator humidity provided by the invention.As it is shown in figure 1, the method controlling respirator humidity includes:
S10: judge whether patient is currently suction condition according to the respiratory air flow of patient.If it is, enter step S11, if it does not, enter step S12；
S11: output air-breathing control signal.Enter step S13.
S12: output expiration control signal.Enter step S14.
S13: enter air-breathing mode according to air-breathing control signal and export air-breathing humidification power.
S14: enter expiratory mode according to expiration control signal and export expiration humidification power.
Wherein, air-breathing humidification power is more than humidification power of exhaling.
In the present embodiment, first judging whether patient is currently suction condition according to the respiratory air flow of patient, it is to be understood that under normal circumstances, the breathing state of patient only has two kinds of situations, and a kind of suction condition one is expiration state.Therefore, when the breathing state of patient is not for that state of necessarily exhaling of suction condition.When the breathing state judging patient is suction condition, then output air-breathing control signal, otherwise output expiration control signal.It is understood that air-breathing control signal in the present invention and expiration control signal are control signals two kinds different.Air-breathing control signal is to control the signal of humidifier humidifies when patient's air-breathing, controls the signal of humidifier humidifies during expiration control signal when patient exhales.Since two kinds of control signal differences, then the air-breathing humidification power that humidifier exports after entering air-breathing mode according to air-breathing control signal and the moral integrity humidification power according to output after expiration control signal entrance expiratory mode will be different.Additionally, it is generally the case that the gas that client need humidity is bigger sucks, and the humidity requirement of gas during for exhaling is not high, and therefore, in the present invention, air-breathing humidification power is more than humidification power of exhaling.
The method of control respirator humidity provided by the invention, breathing state according to patient controls the humidification power of humidifier, when patient's air-breathing, controls humidifier and enters air-breathing mode and export air-breathing humidification power, when patient exhales, control humidifier and enter expiratory mode and export expiration humidification power.As can be seen here, the method controls the output of humidifier according to air-breathing and expiration two states, sick Man's Demands can be met at the air-breathing humidification power ensureing the humidifier output when air-breathing, and the expiration humidification power of the humidifier output when exhaling is relatively low, reduce the use cost of respirator, decrease the waste of the energy.
On the basis of above-described embodiment, step S11 includes:

In order to better provide, for patient, the air that quality is higher, in the present embodiment, determine the air-breathing control signal of final output according to the gas flow of humidification pipeline porch and gas moisture signal.
Owing to when power is certain, if gas flow is different, gas humidity is different, the moisture signal of the air of humidifier final draft output is also different.Therefore, in the present embodiment, it is necessary to prestored a humidity calibration rule, have in this rule different gas flow signals and different gas humidity signals corresponding target humidification signal.Therefore, after obtaining gas flow signals and gas moisture signal, humidity calibration rule maps out target humidification signal.This target humidification signal can regard a desirable moisture signal as, it is possible to obtains according to practical experience.In being embodied as, gas humidity signal and target humidification signal can gap to some extent, this gap is exactly require over humidifier gas humidifies to reach the requirement of target humidification signal.
On the basis of above-described embodiment, step S12 includes:
S120: obtain the gas humidity signal of humidification pipeline porch.
S121: judge whether gas humidity signal meets pre-conditioned.
If it is, enter step S122, if it does not, enter step S123；
S122: output keeps the control signal of current power.
S123: output regulates the control signal of current power.
Wherein, expiration control signal includes the control signal keeping current power and the control signal regulating current power.
In the present embodiment, when when expiration state, obtaining the gas humidity signal of humidification pipeline porch, it is judged that it is pre-conditioned whether moisture signal meets.Here the pre-conditioned condition that can be humidifier and disclosure satisfy that the lowest power consumption of requirement.If current gas moisture signal meets requirement, then keep the control signal of current power to humidifier output, if current gas moisture signal is unsatisfactory for requirement, then regulate the control signal of current power to humidifier output.It is to be understood that when expiration state, humidifier can be duty, it is also possible to be off working state, if off working state, then output keeps the control signal of current power that humidifier can be allowed to keep off working state, namely need not humidify gas.
