The concrete meaning of language in embodiments of the present invention.
Fig. 1 is the structural schematic diagram of the expiration duration instruction device provided in an embodiment of the present invention for spirometer, such as
Shown in Fig. 1, including：Microprocessor 101, gas flow transducer 102 and indicating module 103；The microprocessor 101 specifically includes meter
Shi Danyuan 1011 and control unit 1012, the gas flow transducer 102 are connect with timing unit 1011, the timing unit 1011
It is connect with control unit 1012, described control unit 1012 is connect with indicating module 103；The timing unit 1011 is used in gas
After flow sensor 101 detects expiratory airflow, expiration duration is recorded；Described control unit 1012 is used for according to timing unit 1011
The expiration duration of record, control indicating module 103 indicate expiration duration.
Wherein, microprocessor can be the core processor in spirometer, can also be the microprocessor being separately provided；
If the microprocessor being separately provided, then should be communicated by wired or wireless mode with the core processor in spirometer
Connection；It will be said using the embodiment for using the core processor in spirometer as microprocessor in the embodiment of the present invention
It is bright, but the protection domain of the embodiment of the present invention is without being limited thereto.
Specifically, the exhalation vents in spirometer can be arranged in gas flow transducer 102, and gas flow transducer 102 can be with meter
The connections of Shi Danyuan 1011；When user starts to exhale to spirometer, gas flow transducer 102 detects air-flow, and triggering timing
Unit 1011 starts timing, and the duration that timing unit 1011 is recorded is expiration duration；And timing unit 1011 is single with control
Member 1012 connects, and control unit 1012 can be according to expiration duration in predetermined time or in expiration whole-process control indicating module
The duration of 103 pairs of expiration indicates.
Expiration duration instruction device provided in an embodiment of the present invention for spirometer is touched by the way that gas flow transducer is arranged
It sends out timing unit record expiration duration and control unit and indicating module progress duration instruction is controlled according to expiration duration so that
Gauger understands expiration duration in real time in the measurement process for carrying out forced vital capacity, improves the success of forced vital capacity detection
Rate reduces pendulous frequency and the body burden of gauger, avoids the inadaptable or syncope for causing gauger.
Based on any of the above embodiments, the indicating module 103 includes at least one luminescent device, described to shine
Device integration or the surface of shell for being removably disposed in spirometer；Correspondingly, described control unit 1012 is used for basis
The expiration duration that timing unit 1011 records, timing controlled luminescent device shine.
Specifically, indicating module 103 may be used the mode of indicator light, and the instruction of duration by luminescent device light or
Extinguish to prompt；As shown in figure 3, indicator light 301 can be arranged in the outer surface of spirometer shell, i.e., it is integrated with spirometer
Change or is detachably arranged；Or it is arranged in the external position that can be seen by measured；Wherein, detachable setting is so that lung is lived
Gauge is not used in when measuring forced vital capacity, and indicating module can be removed using as common spirometer, and be implemented below
All kinds of indicating modules in example are detachable, and effect is identical with this, and is repeated no more later.
For example, 1 luminescent device can be set, and when length reaches setting duration (such as 6 seconds) upon exhalation, luminescent device point
It is bright, prompt duration enough；Or the multiple luminescent devices of setting, it can be marked by the luminescent device on the shell of spirometer pair
The duration answered, luminescent device light, and indicate the duration for reaching mark；Such as 2 luminescent devices are set, by the 1st luminescent device
Mark 3 seconds, the 2nd luminescent device side mark 6 seconds, and control unit controlled two photophores respectively at the 3rd second of expiration and 6 seconds
Part lights, to prompt gauger.
It should be noted that luminescent device is arranged in spirometer shell, the loophole being specifically provided on shell
Under, and light transmission hole site is visible to gauger.
Based on any of the above embodiments, the indicating module 103 includes multiple luminescent devices, multiple luminescent devices
It arranges in order；Correspondingly, the expiration duration that described control unit 1012 is used to be recorded according to timing unit 1011, according to arrangement

Specifically, multiple luminescent devices 301 can according to being centainly ranked sequentially, such as sector, circular arc etc. it is regular and
Beautiful spread geometry；As shown in figure 3, LED1~LED6 is indicator light (be luminescent device), VCC is power supply, U1 be with
The microprocessor (including timing unit and control unit) of timing function and control function；When in use, at regular intervals
(at the time of such as at the time of 0.5 second, 1 second) just lights a luminescent device, and (lighting can be by controlling luminescent device power supply
Connection situation), and the sequence lighted putting in order according to luminescent device, until detection terminates or reach 6 seconds (to reach 6 seconds
All indicator lights are all lighted afterwards)；The light beam that indicator light is sent out through the loophole on shell is irradiated from interiors of products
Come, its visible light beam of gauger.
Below in conjunction with Fig. 2 and Fig. 3, it is illustrated when with the quantity of luminescent device being 6：Carrying out forced vital capacity
When detection, gauger starts to exhale, upon exhalation between up to after 1 second, the 1st indicator light is lighted；After reaching 2 seconds between upon exhalation,
1st and the 2nd indicator light are all lighted；And so on, upon exhalation between up to after 6 seconds, the 1st~6 indicator light is all lighted, this
It is secondary be measured after measure next time when starting, 6 indicator lights all extinguish.
Therefore, by according to put in order periodically light each luminescent device one by one can be to gauger's visual indication
Expiration duration.
Based on any of the above embodiments, the luminescent device includes light emitting diode or light bulb.Such as it is single
LED, display formula LED or LCD etc..
Based on any of the above embodiments, the indicating module 103 includes microphone device, the microphone device one
Change or be removably disposed in the surface of shell of spirometer；Correspondingly, described control unit 1012 is used for according to timing unit
The expiration duration of 1011 records, timing controlled microphone device sounding.
Specifically, indicating module 103 can also indicate expiration duration by the way of sounding；Such as in setting
Moment makes a sound long prompt when being carried out to gauger.The setting of microphone device is similar with luminescent device, detachable or one
Change the surface of shell being arranged in spirometer, setting can effectively make a sound in surface of shell, be conducive to auditory tone cues.And
And control unit 1012 can control acoustical generator sounding in given time.
Based on any of the above embodiments, the microphone device includes voice prompting device or buzzer.Specifically, language
The inside of sound prompting device can prestore the voice data for being useful for prompt, such as expiration duration is from 0 second to 6 second,
1012 control voice prompting device of control unit sends out prompt tone corresponding with expiration duration per second；Such as it at the 2nd second, sends out
The sound of " expiration duration is up to 2 seconds " sent out the sound of " expiration duration is up to 3 seconds " at the 3rd second；Loud speaker and buzzer etc.
The similar principle for capableing of microphone device is similar.
Based on any of the above embodiments, the indicating module includes vibrator；Correspondingly, described control unit is used
In the expiration duration recorded according to timing unit, the vibration of timing controlled vibrator.
Specifically, long prompt when indicating module 103 can also be carried out from the mode of vibration；It is similar with above-mentioned microphone device,
It is controlled and is vibrated by control unit 1012 at the time of vibrator can be corresponding to preset duration, to be prompted.
