Description
Technical field:
The present invention relates to a kind of respiratory training instrument and the methods for adjusting trainer's breathing pattern.
Background technique:
The concept of respiratory training:
A, air-breathing training: air-breathing is a kind of active process, and need lean on actively to shrink expands thoracic cavity, drops intra-pulmonary pressure
It is low；When intra-pulmonary pressure is subatmospheric, air will be sucked in lung.Air-breathing (quiet inspiration) when normal by
Diaphragm and external intercostals are responsible for, when diaphragm is shunk and external intercostals is shunk, diaphragm film location downwards and thoracic cavity simultaneously to
It outside and moves upwards, thoracic cavity volume becomes larger, and relatively, pressure becomes smaller, and the air of atmosphere is just sucked into lung.However, firmly
When air-breathing or deep breathing (forced inspiration), other than diaphragm is shunk, air-breathing is also needed to assist flesh-chest rope mastoid process
The assistance of flesh, trapezius muscle, scalenus and external intercostals, the contraction of chest rope papillary muscle is so that breastbone up mentions, scalene contraction
So that upper rib cage up mentions；The result of these contraction of muscle to lift on width of chest, thoracic cavity space enlargement to the limit.
Inspiratory muscles can be trained by some auxiliary appliances, these equipment provide some impedances appropriate.It trained
Inspiratory muscles can increase the depth and range of breathing, increase the efficiency of breathing, the efficiency of further lifting motion.
In addition, inspiratory muscles training has been widely used for chronic obstructive lung desease patient, due to chest wall physical abnormalities
Unsuitable when (because feeling elated and exultant, air-flow limitation leads to overpressure respiration) is with the ventilation of high demand to exert oneself, the inspiratory muscles of the patient of this group is special
It is not weak, so inspiratory muscles training is especially powerful to these specific groups.
B, exhale training: the mechanism of expiration is because of pressure difference with air-breathing as, but exhaling is because of intrapulmonic pressure
Power is greater than atmospheric pressure.Expiration (passive expiration) when normal, there is no the contractions of muscle, when diaphragm and external fin
Between muscular relaxation when, thoracic cavity becomes smaller, and intra-pulmonary pressure becomes larger, thus air by spuing in vivo.But when external air draught by
Hinder, or for it is some once suffered from or patient with chronic lung disease for, expiration is not exclusively just one and loosens
Process, and need the participation of expiratory muscle.When forced expiration (active expiration), be responsible for exhale internal intercostals and
Abdominal muscle starts to shrink；Internal intercostals contraction makes rib cage is past to move down, and contraction of abdominal muscle compels rib cage toward compressing abdominal viscera is moved down
Make diaphragm toward convex, and thoracic cavity volume is made to be reduced to minimum, intrapulmonic pressure increases to maximum, and intracorporal carbon dioxide could be exhaled largely
Out.Respiratory training feel elated and exultant for the efficiency of internal gas exchanges, there is significant help.
Respiratory training instrument is common respiratory training device, which is formed by the size in setting respiratory air flow channel
Certain resistance carries out weight training.The training method have one it is intrinsic be limited in, training load not only with airflow channel
Gap size it is related, also with airflow rate change and change, respiration rate is faster, and air-breathing is more difficult.Therefore control breathing
Mode is extremely important, and in fact this training method hardly results in accurate monitoring.

Monitoring and feedback of the signal as respiratory air flow speed in data source person's training process of coming analyzing and training, make trainer can be according to anti-
Present the speed that result adjusts expiration, air-breathing.
To solve this technical problem, the technical solution adopted by the present invention is that: will be believed by the collected audio of audio collection device
Number it is transferred to data processor, is converted audio signals by data processor to be constituted the map of coordinate system with amplitude and time
Or the map of coordinate system being constituted with power and time, and trainer is shown to by display, trainer can pass through the steady of map
It is qualitative to adjust respiration rate.
By the display of map, trainer can be visually observed that oneself exhale, air-breathing when air-flow caused by sound
The variation of the amplitude or power of sound, and by self-control, so that the waveform for indicating amplitude or power in map is become gentler, with
This realizes the adjusting to trainer's breathing pattern.
The further technical problems to be solved of the present invention are: providing a kind of using the above-mentioned collected audio of respiratory training instrument
Method of the signal as the lung function parameter of the data source person that comes analyzing and training.
To solve this technical problem, the technical scheme adopted by the invention is that: first with the second acoustical generator replacement first hair
Sound device blows cylinder for second and the second acoustical generator assembles, and then trainer blows cylinder against second and blows, the sound that the second acoustical generator issues
Audio signal is sent to data processor after being acquired by audio collection device by wave, by data processor by the audio signal shape
It is calculated according to the relationship of sound power and time based on sound at the map for being constituted coordinate system with sound power and time, and further
Pulmonary function test (pft) project FEV1 ', the PEF ' and FEV1 '/FVC ' value of frequency, then according to proportionality coefficient by the lung function based on audio
Can test item FEV1 ', PEF ' and FEV1 '/FVC ' value be converted to pulmonary function test (pft) project FEV1 based on gas flow,
The value of PEF and FEV1/FVC, the final lung function data for obtaining tester
The respiratory training instrument acquisition that cylinder, the second acoustical generator and audio collection device are constituted is blown by second using of the present invention
The audio signal arrived, to determine the lung function parameter of trainer, this method be can be effectively reduced because acquiring for analyzing lung function
Data source and the cost paid so that numerous users in daily life can when be often used the present invention and say yes breathing instruction
Practice instrument to detect lung function, timely medical treatment of finding the problem in time.
