A kind of lung functions as shown in Figure 1 restore supplemental training device, including are connected to the (four-way pipe 2 of four-way pipe 2 The Axis Cross of lumen is cross or X-shaped) four nozzles at 1, two control valve of expiration mouth and Response Division 4, and resistance Flow tube 5, test section 6 and control centre, two of them control valve are connected at two of four-way pipe 2 opposite ports, expiration mouth 1 with Response Division 4 is connected at other two opposite port of four-way pipe 2.Pass through hose between the expiration mouth 1 and the four-way pipe 2 Connection.Two control valves are respectively No.1 control valve 3.1 and No. two control valves 3.2, and No.1 control valve 3.1 and No. two controls Valve 3.2 is solenoid electric valve, wherein the arrival end of the outlet end connection choke tube 5 of No.1 control valve 3.1, No. two control valves 3.2 outlet end and the outlet end of the choke tube 5 pass through the venturi tube inlet end that hose is connected in test section 6 respectively. The 5 lumen middle section of choke tube is contracting cavity configuration (Fig. 9, Figure 10 .1, shown in 10.2).

As Fig. 1 to Fig. 3, Fig. 8 .1 to 8.2 shown in, the Response Division 4 includes the attachment base 41 connecting with the four-way pipe 2. The attachment base 41 is equipped with axial cavity, is equipped with strain component 42 at the middle part of cavity, the strain component 42 includes elasticity Film 421 and the foil gauge 422 being fixed in elastic membrane 421, the foil gauge 422 are connected with outer lead road.Elastic membrane 421 will be even The cavity of joint chair 41 blocks, under pressure 421 Tensile of elastic membrane and deform, foil gauge can generate synchronous deformation.Even Joint chair 41 can be connected through a screw thread with four-way pipe 2, be strained in component 42 for the annular seating and attachment base 41 of elastic membrane 421 to be arranged Inner cavity between also for be threadedly coupled, and annular seating outer end setting rib hole 423 be used for installing and dismounting, rib hole 423 Internal diameter is greater than the through-hole aperture of its inner end setting, and to prevent in installing and dismounting operation, tool damages elastic membrane.Even The settable cock cap 43 in the port of joint chair, protects elastic membrane 421.

3.1, No. two control valves 3.2 of the No.1 control valve, Response Division 4 and amplifier 66 are connected to the control centre (the incoming signal of the signal and amplifier transmitted containing microprocessing unit to Response Division is analyzed and processed).The control centre It can specifically be set according to the variation of the foil gauge 422 and control opening for 3.1, No. two control valves 3.2 of the No.1 control valve Closed state makes 3.1, No. two control valves 3.2 of the No.1 control valve select one in the conductive state.The control centre can receive The signal that the amplifier 66 transmits is handled, and the real-time pressure and expiratory gas flow of exhaled gas are calculated.

After the gas of exhalation enters four-way pipe, certain internal pressure is formed in the lumen of four-way pipe, is deformed elastic membrane, And then foil gauge is deformed, change its resistance value, 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 value) of foil gauge is different, and foil gauge, to control centre, is being controlled by connection Center can alternately control the opening and closing of two control valves according to the variation of the resistance value size of foil gauge.So foil gauge resistance value is real-time Value be it is corresponding with the real value of breath pressure, the real value of breath pressure thus can be obtained after control centre is handled, very To the waveform diagram of breath pressure variable condition.

The limit section (being assumed to be 0.1a to 1a) of foil gauge resistance value 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 belongs to next interval range.Such as work as resistance value No.1 control valve is opened when in 0.1a -0.35a section, No. two control valves are closed, when resistance value is in 0.35a -0.65a section When No. two control valves open, No.1 control valves closure.And according to respiratory training process or the difference of patient, control can be passed through Center processed adjusts the control situation that specific section corresponds to control valve, can also such as be set as, and resistance value is in 0.1a -0.35a section Or when 0.35a -0.65a section No.1 control valve open, No. two control valves closure, when resistance value be in 0.65a -0.8a section or No. two control valves are opened when 0.8a -0.95a, No.1 control valve is closed.Such design, which can not only be known in training process, exhales Atmospheric pressure state value, and the device can be according to the people and the time set, guarantee training of safety, be effectively performed.

It, can be by the programming module of control centre specifically according to such as the method for operating of two control valves of optimal control Lower thought setting.That is, control valve is not to stand when the resistance value of foil gauge enters adjacent interval range by an interval range It acts, but after entering another section and stablizes (such as 1 second or 2 seconds) the rear movement of maintenance a period of time.

(being obtained by Response Division and test section) signal is analyzed and processed in control centre.It is at least wanted after analysis processing Ask parameter values or the waveform diagrams such as the real-time pressure that can calculate the exhaled gas that can most indicate respiration capability and expiratory gas flow.To letter Number software section being analyzed and processed is not belonging to the claimed range of this patent, the core of this patent be how reliable design, Practical hardware configuration, to obtain in exhalation process with physiologic information parameter existing for expiration behavior.

After signal is passed to control centre's progress noise reduction process by amplifier, entering signal processing and analysis module are carried out each The analytic operation of kind parameter.Control centre can be by the airstream vibration frequency of real-time monitoring, by display device with the shape of waveform Formula is shown, to intuitively show the state change of expiration, observes training effect, can be to incoming signal at Reason, obtains breath pressure changing value and expiration amount changing value and total value.

The resistance value section of two control valve states of the corresponding control in Response Division can be adjusted according to trained progress, or changed The cavity diameter of choke tube, the internal pressure value of (four-way pipe lumen) when changing starting training.Because when exhaled gas, in ventilation pipe There are certain internal pressures, it is possible to make to increase oral cavity and airway pressure in expiratory phase, prevent small airway from falling into too early and close, reduce Alveolar excessive residual gas.So can reduce respiratory rate by resuming training, increase tidal volume, so as to improve alveolar Effective ventilatory volume is conducive to the intake of oxygen and the discharge of carbon dioxide.

It is general that No.1 control valve when originally is required to open, so the choke tube of design acts on shape in four-way pipe by choked flow At internal pressure, the deflection for originally driving foil gauge to occur is not enough to drive No. two control valves to open, and with trained It promotes, after respiration capability is improved, is enough that No. two control valves is driven to be opened in the internal pressure side that four-way pipe is formed, No.1 control at this time Valve closure processed.The interval range of No. two control valves variation is controlled by adjusting foil gauge deformation resistance value, can adjust No. two control valves Opening time.

The Venturi tube being arranged in control centre can be one, and the conducting pipeline that can also respectively correspond two control valves is set Set one.When two Venturi tubes are arranged, control centre is not only analyzed and processed the parameter of its each self-test, but also Integrated treatment is made to the detection parameters of the two, and then carries out comprehensive analysis processing.So a Venturi tube or setting is arranged When two Venturi tubes, the signal analysis and processing mode in control centre is different, and the method taken is also same not to the utmost.
