Description

Feedback-type training for abdominal breath instrument

Technical field

The present invention relates to medical instruments field, more specifically, relate to the feedback-type training for abdominal breath instrument of being with biofeedback effect.

Background technology

Breathing is to keep one of body metabolism and the necessary basic physiological process of other functional activity, and the organ of breathing is lungs, and lungs are subjected to vagus nerve and sympathetic innervation.During the lung expansion, impulsion reaches respiratory center by the vagus nerve centripetal fiber and suppresses to exhale from the alveolar sensor; When lung dwindled, the impulsion of sensing can cause air-breathing again.This reflection claims stretch reflex, and pulmonary stretch reflex that pressurization in the stretching lung of machinery or the lung causes can make blood pressure reduce.This effect also realizes by vagus nerve.In addition, often show as autonomic imbalance in some cardiovascular disease, fan's stop ﹠ go function is impaired.May strengthen fan's stop ﹠ go function by respiratory training, autonomic nerve is restored balance.In addition, have only enough deep breathing to drive away because the body clearing house of not stopping the supple of gas or steam of lung is accumulated in the toxin in the alveolar.The breathing that slows down and deepen us can make the people by constraining to loosening conversion.Can slow down heart beating, blood pressure is tending towards normally, increase the blood flow of digestive system, improve sleep, improve energy, attention and memory.Studies show that the central nervous system of human body has participated in respiratory, breathing can play regulating action to cardiovascular system by sympathetic and parasympathetic nervous, and it mainly shows as respiratory sinus arrhythmia (RSA).The sympathetic nerve hypertonicity is the pathogenic factors of some disease, as hypertension or arrhythmia etc.Sympathetic nerve and parasympathetic nervous be relative equilibrium just often, and parasympathetic tension force shows as sympathetic strong relatively excessively when not enough, and heart rate is accelerated, and blood pressure increases, and enterogastric peristalsis weakens etc.Report is introduced according to the study: the parasympathetic nervous excitement can make blood pressure drops when strengthening relatively, is difficult for the bigger fall of diastolic pressure appearance that descends.Its hypotensive effect can match in excellence or beauty with depressor in some cases, and is more remarkable than simple rest and sleeper effect.

Common most of people gets used to thoracic respiration.It makes respiratory lack efficient, do not use diaphragm muscle when breathing but by means of chest muscle, the lower part of the lobe of the lung is than its middle part and the top more blood that distributing, thoracic respiration can not be got rid of the residual gas of lobe of the lung bottom clean, can not make the bottom of the lobe of the lung obtain more blood exchange.So not only can not make full use of the function of lung, and breathe and also not reach the effect of loosening, can make the people feel slack, not have vigor.

Ventral breathing can maximally utilise lung tissue, fully carries out gas exchange, makes lung tissue obtain healthy exercise.Volume expansion in thoracic cavity can make heart obtain abundant diastole when carrying out ventral breathing, helps the blood supply oxygen supply of cardiac muscle.Owing to every the motion of belly of muscle wall muscle and the variation of intra-abdominal pressure, make abdominal visceral browser obtain natural massage, gastrointestinal motility power increases, and has quickened the air emptying function of stomach and the absorption function of small intestinal.Ventral breathing also makes the function of large intestine increase, and impels the eliminating of intravital refuse of machine and enterogenous endotoxin.

The purpose of training for abdominal breath is in order to strengthen breathing muscle, to improve pulmonary function on the one hand; Be to regulate the human body autonomic nerve on the other hand, thereby reach the purpose of health preserving and treatment cardiovascular disease.

From the above, carrying out training for abdominal breath has and improves and strengthen human body and pay sympathetic tension function.Respiratory sinus rate uneven (RSA) is to spy on human body to pay sympathetic tension force window easily.Respiratory sinus rate uneven (RSA) may be interpreted as: heart rate is accelerated when air-breathing, decreased heart rate during expiration.Under normal circumstances, heartbeat is subjected to vagal regulation and control, and the former activity of cardiac vagal mainly depends on the activity of importing into of pressure receptor, and the latter depends on the height of mean arterial pressure and pulse pressure again.Under the normal condition, this kind is stable is subjected to that inspiratory center is active prevents when importing activity into phasic property.All in reticular formation of brain stem, the region of anatomy is more approaching for respiratory center and vasomotor center, thereby some respiratory reflexs can occur simultaneously with cardiovascular reflex, carried out correct training for abdominal breath after blood pressure can descend.Therefore electrocardiosignal, blood pressure etc. also are the important reference factors of training for abdominal breath.

The method of relevant training for abdominal breath was a lot of in the past, general all is that mode with the literal teaching-guiding occurs, being seen training for abdominal breath instrument, also just ventral breathing amplitude, frequency etc. and the directly related parameter of breathing are detected, and comprise synchronous pilot signal etc., and do not pay the supervision of sympathetic tensile respiratory sinus rate uneven (RSA) to influencing human body, also not to the measuring ability of electrocardiogram, heart rate, blood oxygen saturation, non-invasive blood pressure etc.We can say that in the past training for abdominal breath instrument can not more, more fully reflect the information and the effect of training for abdominal breath.

Biofeedback therapy is a kind of conscious relaxation therapy, it utilizes instrument to extract some biological information (as myoelectricity, Pi Wen, heart rate, breathing, blood pressure, brain electricity etc.) in the body relevant with the outpatients mental state physiological process, mode with vision or audition is shown to patient's (being information feedback) then, patient is by the cognition to these information, association controls the psychological physiological activity of self consciously, and whole body is loosened.

Summary of the invention

The problem to be solved in the present invention provides a kind of training for abdominal breath instrument, when making training for abdominal breath, detect the RSA state in real time, together with the cardiovascular reflex that occurs simultaneously with respiratory reflex, comprise that other relevant physiological signal feedback such as electrocardio, blood pressure signal give by the trainer, energy strengthens by the confidence of trainer to training for abdominal breath, thereby further improves the effect of training for abdominal breath.This is a kind of with biofeedback training and training for abdominal breath a kind of new training mode that combines and the device that embodies this pattern.

The technical scheme of feedback-type training for abdominal breath instrument is among the present invention: comprise by interface, memorizer, sequential and arrange the pico computer that circuit, signal acquisition circuit, bus, power supply and mainboard are formed, key circuit, display and pick off, described pick off inserts described mainboard by signal acquisition circuit, it is characterized in that:

Described pick off is EGC sensor and respiration pickup;

Utilization is from the electrocardio ripple and the respiratory wave signal of described electrocardio and respiration pickup acquisition, calculate respiratory sinus arrhythmia quantitative expression value by described pico computer, on described display, show, make it constantly know from experience, to revise the ventral breathing essential of exercise according to feedback information for feeding back to the trainee, reach the effect of getting twice the result with half the effort.

The feedback method technical scheme that is used in the feedback-type training for abdominal breath instrument among the present invention is: it is characterized in that comprising the steps:

(1), obtains electrocardio ripple, respiratory wave, blood pressure and oxygen saturation signal from electrocardio, breathing, non-invasive blood pressure, oximetry sensor;

Feedback-type training for abdominal breath instrument has both the characteristics of bio signal feedback and respiratory training, in respiratory training, in time the effect of training is fed back to the trainee, make the trainee can know the correctness of own breathing pattern at once, strengthen the confidence and the effect of training.The signal of the collection of present embodiment comprises that blood pressure, abdominal part are inhaled and expiration state, electrocardio, blood oxygen etc., refers to that by blood pressure cuff, inflation bellyband, electrocardioelectrode, blood oxygen folder forms 1 acquisition of input pickup part respectively; Except that this input pickup part 1, the formation of present embodiment instrument for training also comprises by blood pressure module 2; Arrange pico computer that circuit 5, embedded computer board 6, bus, power supply 10 and not shown memorizer form as signal processing by signal acquisition circuit 3, computer interface 4, sequential; Form segment signal output by liquid crystal display 7; Parts such as key circuit 9 as the described mainboard 6 of being connected to of importation can comprise printer 8 in the output.Also being provided with the not shown device of being controlled by described mainboard 6 for blood pressure cuff drum and venting reaches to inflating the device of bellyband charge/discharge gas.

Below be described in detail the work of present embodiment training for abdominal breath instrument.

At first will tie up to abdominal part as the inflation bellyband of the band pressure/electric weight sensing element that produces the air-breathing and expiration status signal of abdominal part, the charge/discharge gas device can be inflated to certain pressure with it automatically under mainboard 6 controls, abdominal respiration causes abdominal part to rise and fall, inflation bellyband pressure is changed, be converted to the signal of telecommunication and represent that breathing rate and its to time changing curve, show on display.As exhale/the inflation bellyband of the band pressure/electric weight sensing element of the pick off of suction condition is an example, its form is not limited to this, any respiration pickup that other is fit to also is available.The data that also have heart rate, blood pressure, blood oxygen saturation that show on display and it are to the changing trend diagram curve of time, and each the expiration and the air-breathing sinus rate that causes uneven (RSA).About passing through of comprising in blood pressure module and the signal acquisition circuit hardware that electrocardioelectrode, blood oxygen saturation electrode etc. become physiological signal into the signal of telecommunication and processing and amplifying constitutes has been current known technology, need not to give unnecessary details.

The method of being obtained RSA by electrocardiosignal has multiple: in general, a normal electrocardio (ECG) signal is made up of a series of waveform, and these waveforms are to distinguish by the zero potential of excitement.Under normal circumstances, these ripples are periodically repeating according to the excitement that sinuatrial node produces.Briefly, a normal ecg wave form is made up of P ripple, QRS wave group, T ripple etc.For concrete each ripple, all corresponding cardiomotility and electrophysiological moment.Compare with other waveforms in the electrocardio, the R ripple has higher amplitude.

In addition by spectrum analysis as can be known, the center frequency-band of QRS wave group is (this frequency is also referred to as the characteristic frequency of QRS wave group) about 17Hz, and bandwidth is about 10Hz, and the frequency of T ripple, P ripple, baseline drift etc. all is beyond the low side of this frequency.More than 2 be the distinguishing feature that the QRS wave group is different from other waveform, the algorithm of various detection QRS wave groups mostly is to utilize its characteristics that are different from other waveform and noise to realize detecting.

Electrocardio QRS wave group detects concrete grammar and mainly contains following several aspect: wave filter method, template matching method, wavelet analysis method, bank of filters method, neutral net method etc.As example, what present embodiment adopted is that amplitude is differentiated and frequency is differentiated the template matching method that combines, and in the electrocardio QRS wave group that detects, analyzes RR interval by shooting, again from analyzing the RSA quantitative values RR interval and the respiratory wave by shooting.

Specify process now about the above-mentioned RSA of obtaining.

At first, explanation is about the extraction of issue N between RR, it carries out like this: to the detected respiratory wave of respiration pickup at every turn by time shaft respiratory wave amplitude M be 0 o'clock time difference as T sample time, then ecg wave form RR interval quantity is in the meantime counted, its numerical value is the N value.Hence one can see that, and the N value is along with inspiratory duration and expiratory duration alternately occur and the numerical value of variation.See Fig. 6.This is based on per half breathing cycle is the quantity of counting N in sample time, intends getting this setting in this example and narrates.Can certainly with a breathing cycle as sample time T count the N value.

An amount below will be discussed: adjacent R R interval difference root-mean-square (RMSSD) also calculates it, and is relevant with radio-frequency component in the frequency-domain analysis because RMSSD has reflected the quick variation of RR interval, its formula such as following (1) formula:

$\mathrm{RMSSD}=\frac{\sqrt{\underset{i=1}{\overset{N-1}{\mathrm{\Σ}}}{({\mathrm{RR}}_i-{\mathrm{RR}}_{i+1})}^2}}{N}\left(\mathrm{ms}\right)---\left(1\right)$

RR interval sum when N is at every turn air-breathing or expiration in the formula (as above-mentioned, N also can add the sum in the air-breathing cycle for exhale at every turn), RR _iAnd RR _I+1Represent preceding 1 and back 1 time span of adjacent two RR intervals respectively, unit is ms.So, the RMSSD reflection of this moment is the average level that changes the air-breathing or expiration RR of respiratory wave interval.Certainly, as above-mentioned, when getting in the breathing cycle when calculating N and counting, the average level that the RR interval changes in its reflection breathing cycle.

Respiratory sinus arrhythmia is relevant with the breathing cycle, and heart rate is accelerated when air-breathing, decreased heart rate during expiration, and its speed cycle just equals a breathing cycle.Relevant according to above-mentioned choosing method with the breathing cycle to N in (1) formula, then calculate the quantitative assessment index that adjacent R R interval difference root-mean-square (RMSSD) can be used as respiratory sinus arrhythmia (RSA).This shows that RSA is the numerical value that constantly changes with expiratory phase and expiration phase.When abdominal respiration is trained when effective, it is big that the excursion up and down of RSA waveform becomes.See Fig. 7, this curve is to calculate the variation with the training time that income value is represented by above (1) formula.The RSA data are used as one of criterion of training for abdominal breath effect in this example.

Should be noted that, it is a kind of in the present embodiment design that the RSA of above example detects step, in fact the analysis of heart rate variability has a lot of methods to select in theory, for example a bottom RSA curve has the trend that rises gradually in the trend curve of Fig. 2 right side, can be after certain training time, observe the training effect, this trend curve is to obtain on for the each air-breathing basis that adds RR interval sum when exhaling at N.In other words, two of this instrument for training N value kinds of selections all are available.This instrument for training is only required and is detected with to breathe relevant respiratory sinus rate uneven, therefore, is necessary to consider the parameter relevant with breathing and respiratory training when design.Exemplify several below:

Because at present in the world the definition of RSA is not restricted to an absolute mathematical formulae, we can be with method commonly used in the statistics, as RR interval meansigma methods RR _AVEWith RR interval standard deviation (SDNN, SD).When choosing RR interval timing statistics scope will with the abdominal respiration training time with pay close attention to content and conform to.

Among the RSA variation of RR interval also the geometric method of available analyses express.In general the geometry method is more suitable in the observation of medium-term and long-term (as 24 hours), it is an innovation that this method is applied in the feedback-type abdominal respiration instrument for training, reason is can identify the type of heart rate variability by playback function with this method, observe the training effect more intuitively, optional 2 hours of observing time was not waited to 24 hours, can carry out the periodic analysis training effect, be convenient to relatively compare mutually with self.Can use the width method of 1. measuring the specified level density histogram, become measurement heart rate variability; 2. using has the shape of mathematical definition to come the match geometric figure, for example uses triangle approximate densities rectangular histogram, with the approximate difference value histogram of exponential curve, uses the parameter evaluation heart rate variability of these mathematic graphs then.Also the method for useful spectrum analysis is also passable.

To sum up, when utilizing RSA to change to come the effect of labelling training for abdominal breath, use be electrocardio ripple and respiratory wave.In computer, be used for abovely extracting R from the electrocardio ripple and involving meter to get the program of N value be routine techniques, need not give unnecessary details.

In view of blood pressure and blood oxygen saturation also are the criterions of the direct effect of training for abdominal breath, at electrocardio, breathe outside the transducing signal and can also detect blood oxygen saturation and blood pressure and heart rate signal, and show, to feed back to the trainee.

The input signal of blood pressure comprises systolic pressure and diastolic pressure, is obtained the input mainboard by blood pressure module by blood pressure cuff.

The input signal of blood oxygen saturation refers to that by blood oxygen folder is through signal acquisition circuit and interface input mainboard.

Above-mentioned heart rate, breathing rate, RSA, blood pressure and blood oxygen saturation are revealed, and can be the feedback parameters that belongs to the training effect.

Requirement according to the training for abdominal breath method, can further in the memorizer of pico computer, set the ventral breathing bootmode in the embodiments of the invention, it is a kind of expiration of setting and air-breathing to time relation, can have multiple, it can for the trainer select the back be presented on the display by bus.

Example explanation now training method, requirement and bootmode:

The basic demand of ventral breathing is that the utilization abdominal muscles is breathed, and its objective is to make the diaphragm motion.With the air inlet of nose air flue, abdominal part is heaved simultaneously when air-breathing, and diaphragm is promoted; Give vent to anger with the oral cavity during expiration, diaphragm is descended.As shown in Figure 3.

The pattern of breathing: with air-breathing-exhaling is one-period.Basic skills is: air-breathing weak point generally is no more than 3 seconds; It is long to exhale, to exhale the limit for well.As shown in Figure 4.

For the people who accepts respiratory training for the first time, breathing according to fixed model may be incompatible, so training should be incremental.The respiratory training bootmode that present embodiment is introduced has three kinds, is respectively elementary, intermediate, senior third gear, can also set more kinds ofly certainly, or keys in the setting bootmode by the importation.The trainee can select to be fit to the pattern of oneself by button.

Three kinds of bootmodes that table 1. provides for present embodiment, wherein the expiration of fine mode is a batch (-type), exhales 5 seconds for the first time, pauses 1 second; Continue again to exhale 5 seconds, paused 1 second; Exhaled at last 6 seconds.See Fig. 5.

Table 1. is breathed bootmode

	Elementary pattern	Intermediate model	Fine mode
				Breathing rate
	10 times/minute	6 times/minute	3 times/minute
				Inspiratory/expiratory	????1∶2	????3∶7	????1∶9
Inspiratory duration	2 seconds	3 seconds	2 seconds
				Expiratory duration	4 seconds	7 seconds	18 seconds
A training time	20 minutes	30 minutes	30 minutes

Fig. 2 is an exemplary plot of present embodiment indicator screen.There except showing selected bootmode figure (referring to Fig. 2 upper left side), also show (seeing Fig. 2 bootmode figure right side) trainee's abdominal respiration indicator diagram and error scale (deducting trainee's breath signal difference percentage ratio with bootmode represents), allow the trainee can observe oneself respiratory pressure and error size quantitatively, be convenient to adjust at any time breathing state, accurately follow the tracks of " bootmode ", making every effort to error is zero.Training can be set a time span, and for example 20 or 30 minutes, as the training duration.In addition, at set intervals, such as 5 minutes, instrument is measured trainer's blood pressure automatically, and data such as heart rate, breathing, blood oxygen saturation and RSA can be shown to the trainer as the bio signal of feedback together.If it is correct that trainer's breathing pattern is followed guiding, train after 10 minutes the blood pressure 10-20mmHg that generally can descend, RSA can strengthen.The change procedure of heart rate in the training process, breathing rate, blood pressure, blood oxygen saturation, RSA can printout, for trainer or the reference of doctor's postmortem analysis.Fig. 2 bottom is the roll display ecg wave form also.

The workflow of present embodiment instrument for training can represent that this figure understands easily with Fig. 8, need not explain in detail.So-called learning state refers to the learning functionality that this instrument has, can be with trainee's breathing characteristic, rule input instrument, and recorded and stored and report can be the training mode of selecting to be fit to reference are provided.

Fig. 9 is the process of three kinds of bootmode workflows of this example and conversion thereof.

Above said feedback, be that mode with vision is an example, but it also can be audition, for example, with voice the trainer is pointed out.

With a plurality of present embodiment instrument networkings, can be convenient to carry out many many berths of people training for abdominal breath by the unified mode of operation that shows a plurality of extension sets of central machine.
