The control valve 3, Response Division 4 and amplifier 5 are connected to described control unit (containing microprocessing unit to Response Division
The incoming signal of the signal and amplifier of transmission is analyzed and processed).Described control unit can be according to the foil gauge 422
The specific keying for setting and controlling number control valve 3 of change.The gas that described control unit can detect according to sensing element
Stream mode, after setting and controlling control valve 3 to open, time for closing again, usually in the later stage of exhaling, when sensing element detects
During less than there is the air-flow flowed through, the control valve having been switched on just is controlled to close.In other words, the deformation to caused by foil gauge when internal pressure
Amount reach control unit setting make control valve open in the range of after, control unit then drives control valve to be opened, even if (every
It is secondary) end of breath formed internal pressure no longer control unit setting make control valve open in the range of, control valve also will not
Automatic closure, i.e., now control valve still it is electric, it is in the conduction state.Described control unit can receive the amplifier transmission
Signal handled, calculate the real-time pressure and expiratory gas flow of exhaled gas.
After the gas of exhalation enters three-way pipe, certain internal pressure is formed in the tube chamber of three-way pipe, is deformed elastic membrane,
And then foil gauge is deformed, change its resistance, the size for forming internal pressure is big by the diameter of expiration ability and choke tube contracting cavity configuration
Small influence.Internal pressure is different, and the deflection (resistance) of foil gauge is different, and foil gauge is being controlled by connection to control unit
Unit can control the keying of control valve according to the change of the resistance size of foil gauge.So the instantaneous value of foil gauge resistance is with exhaling
Corresponding to the instantaneous value of atmospheric pressure, the instantaneous value of breath pressure, or even expiratory pressure thus can be obtained after control unit is handled
The oscillogram of power variable condition.Before control valve is not turned on, the real-time change state of foil gauge can reflect expiration initial shape
The physiological parameter information of state.
During using the vent line for setting choke tube, dependence is contracting cavity configuration.The general vent line is instructed for early stage
Practice.In the internal pressure that threeway tube cavity is formed, the deflection to caused by foil gauge, the corresponding resistance model for making control valve events
Enclose, be greater than by choke tube formed blow gas pressure, can to caused by foil gauge maximum value.Certainly, in training process
In, it is not that can not set resistance corresponding to foil gauge deformation less than the blow gas pressure formed by choke tube, can be to strain
Maximum value caused by piece, to get more parameter values, there is more accurate, comprehensive understanding to the process for training of exhaling.
The limit section (being assumed to be 0.1a to 1a) of foil gauge resistance is divided into multiple sections, concretely 0.1a-
0.35a, 0.35a -0.65a, 0.65a -0.8a, 0.8a -0.95a etc., end value belong to next interval range.Such as choke tube
The internal pressure of formation, it is 0.4a foil gauge is deformed upon the corresponding resistance limit, then can set foil gauge deform upon pair
When the resistance answered is less than 0.4a, control valve can not be opened.(if the choked flow effect of choke tube in itself has one to set the tone
Between main plot, then under different conditions, corresponding upper limit resistance have it is multiple, so setting typically is made into foil gauge resistance pair
That answers can start the scope of control valve, the maximum rating for the internal pressure that can be formed with reference to choke tube).
In a word, foil gauge deforms upon, and when its change in resistance is in the range of which kind of, just starts control valve, specifically logical
Cross control unit flexible modulation, it is necessary to according to the people and the time and different.Such design can not only know expiratory pressure in training process
