Known, autonomic nervous system (Autonomic Nervous System, ANS) be the control system that major part acts under noncoconscious situation, it is mainly to control viscera function, such as, heart rate, digestion, sweat, and breathe, ANS comprises sympathetic nervous system (SNS) and parasympathetic nervous system (PNS), wherein, SNS is normally responsible for attacking or escaping (fight or flight), PNS is then normally responsible for having a rest and digestion (rest and digest), in many cases, PNS and SNS has opposite effect, one of them can activate a physiological reaction, another then suppresses it.

In vascular system, sympathetic nerve activation can make arterial contraction, and then increase vascular resistance and reduce the blood flow of far-end, and when this occurs in human body, the vascular resistance increased is then to cause arterial pressure to increase, in addition, the vein contraction caused because of sympathetic nerve is then to reduce Venous compliance and blood volume, and then increase venous pressure, so, sympathetic nerve activates the whole structure caused, and increases heart output, systemic vascular resistance (tremulous pulse and vein) and arteriotony.

There is quite a large amount of evidence displays, have the control effects of some autonomic nerves to be changed by physiological feedback training.Physiological feedback training is a kind of learning procedure, and in this program, human body is the physiological process that utilization is realized and control controls by autonomic nervous system, at training period, the bio signal changed along with autonomic nervous system in human body, such as, heart rate or skin temperature, can be monitored, and Real-time Feedback is to experimenter, therefore, experimenter just can by this and strengthen needed for reaction, so for the people having hypertension problem, physiological feedback training is the feasible method affecting blood pressure.

In addition, research also shows, control breathing and can affect sympathetic nerve and parasympathetic balance, generally speaking, sympathetic activity by reducing breathing rate (respiration rate), change tidal volume (Tidal volume) and/or increase exhale during/ratio of intake period and being lowered, therefore, by changing the mode of breathing rate, just can non-invasively and reduce blood pressure simply by the mode reducing sympathetic activity.

Detailed description of the invention

The present invention relates to the blood pressure management device simultaneously with blood pressure adjustment function and blood pressure measuring function, and in the present invention, this blood pressure adjustment function is relevant to the physiological feedback program of autonomic nervous system (ANS, Autonomic Nervous System) by execution and realizes.

First, refer to Fig. 1, its display is according to the block schematic diagram of blood pressure management device of the present invention.This blood pressure management device comprises a control circuit, one inflating pulse pressurized bandage, one pump, and an information provider unit, wherein, this control circuit is in order to control the running of this blood pressure management device, this arm-rest belt in order to the limbs around user, and is undertaken inflating and exitting by this pump, produces pressure change, and then detect the blood pressure of user, and this information provider unit is in order to information is supplied to user.

Moreover, in order to realize the object adjusting blood pressure by carrying out physiological feedback, blood pressure management device according to the present invention further comprises a physiological signal sensing unit, to measure the physiological signal changed because of physiological feedback during execution physiological feedback, and wherein, this physiological signal sensing unit comprises a wear structure, and the physiology sensing element to combine with this wear structure, therefore, during extraction physiological signal, this physiology sensing element is arranged at it user by this wear structure.

At this, especially, this physiological signal sensing unit according to the present invention is the form being embodied as wearing, this is because, as everyone knows, the carrying out of physiological feedback needs the lasting one time section preset, such as, 15 minutes or longer time, therefore, that can need not worry physiology sensing element when performing physiological feedback to allow user arranges situation, the present invention is the mode utilizing wear structure to carry physiology sensing element, and make physiology sensing element be arranged at it user for a long time and stably, this is not only conducive to obtaining stable physiological signal, also user is allowed can more intently to perform physiological feedback program.

Therefore, the program utilizing this blood pressure management device of the present invention to carry out physiological feedback training is: first, with it this physiological signal sensing unit is arranged at by this wear structure by user, to continue to obtain physiological signal at training period, then, after starting physiological feedback training, this control circuit performs the calculation formula preloaded, to analyze acquired physiological signal, and/or analysis result and a goal-selling are compared, afterwards, acquired physiological signal, the information of correlation analysis result, and/or be relevant to the information of comparative result, user is supplied in real time by this information provider unit, user is after receiving information, pass through stabilizing the emotions, modes such as body and mind relaxing and adjust self mental and physical, and then affect autonomic nerve, and reaction is on measured physiological signal and the change of information that provides, therefore, user just constantly adjusts mental and physical by learning the change of information, and target-bound physiological status gradually.This i.e. so-called physiological feedback loop.

So, in the present invention, the information that this information provider unit provides can include, but are not limited to, information acquired when utilizing arm-rest belt to carry out blood pressure measurement, such as, pressure value, and average heart rate etc., and the information of carrying out needed for physiological feedback training, such as, represent the information of real-time physiological situation, and guide the information of user head for target physiological situation.

This information provider unit provides the mode of information to comprise, but be not limited to, the modes such as vision, audition and sense of touch, for example, this information provider unit can be embodied as display element and/or light-emitting component, provides information to utilize the modes such as text importing, graphic change and/or cresset change; Or this information provider unit also can be embodied as sounding module, to provide information by the change of sound frequency or volume or the mode of voice; Or this information provider unit also can be embodied as vibration module, and utilize the variation pattern such as power, length as vibration and information is provided.

In addition, this information provider unit also can be embodied as further, information is exported to an external device (ED) via a wire transmission module or a wireless transport module, give user this information to be provided by this external device (ED), wherein, this external device (ED) can be, but being not limited to, a PC, a smart mobile phone, a panel computer or an intelligent watch etc., need be only the device that this information can be supplied to user, therefore, not restriction.

In addition, the form of implementation of this information provider unit also has many selections, and for example, in a preferred embodiment, it is embodied as and is worn on user parts with it and combines, such as, and arm-rest belt and physiological signal sensing unit; Alternatively, in a further preferred embodiment, it is then embodied as and combines with the operation-interface of device, and such as, display screen, display lamp etc., therefore, can select suitable form according to the demand of actual enforcement.

In the present invention, the effect adjusting blood pressure is reached because main purpose is to affect the physiological feedback program of autonomic nervous system by execution, therefore, the physiological signal that this physiological signal sensing unit senses is the physiological signal of the activity can reacting autonomic nerve.

Generally speaking, the activity of autonomic nervous system is by HRV (Heart Rate Variability, heart rate variability rate) analyze and learn, therefore, one of selection of this physiology sensing element can detect the sensor of user heart rate sequence exactly, for example, utilize light sensors pulse, at this, optical sensor refers to have photocell and light receiving element, and utilize PPG (photoplethysmography, light change in volume graphy figure) principle and obtain the sensor of light signal, such as, utilization penetrates mode or reflection mode carries out gauger, or utilize electrocardioelectrode to measure electrocardiogram, all desirable must in order to carry out the heart rate sequence of HRV analysis, in addition, also available pressure sensor obtains heart rate sequence, such as, utilizes arm-rest belt, or by pressure transducer directly as on tremulous pulse, such as Radial artery, draws heart rate sequence by obtaining continuous pulse wave equally.

At this, the above-mentioned physiology sensing element that utilizes obtains describing of heart rate sequence (no matter being by detecting pulse wave or electrocardiogram), be to represent the time series utilizing physiology sensing element to obtain user eartbeat interval, and namely HRV analysis is analyze this time series.Therefore, in ensuing content, two kinds of narrating modes are optionally used alternatingly, and both represent identical meaning.

And except carrying out HRV analysis, also the activity of autonomic nervous system is learnt by observing the change situation of the physiological signal affected by autonomic nervous system, such as, heart rate, electrodermal activity (EDA, Electrodermal Activity), limbs end is temperature etc. slightly, wherein, heart rate is subject to the regulation and control of sympathetic nerve and parasympathetic nervous, when sympathetic activity increases, heart rate accelerates, when parasympathetic nervous activity increases, heart rate is then slack-off, therefore learns active growth and decline situation between the two by observing heart rate; In addition, because sweat gland secretion only affects by sympathetic nerve, and when sympathetic activity increases, sweat gland activity increases, therefore the mode by measuring electrodermal activity (EDA, Electrodermal Activity) learns orthosympathetic activity increase and decrease; Moreover, because the blood vessel being sent to acral body skin only affects by sympathetic nerve, when sympathetic activity reduces, vasoconstriction reduces, caliber becomes large, blood flow increase, skin surface temperature rise, therefore also by measure limbs end slightly skin temperature and know by inference sympathetic nerve relative to parasympathetic activity increase and decrease.

At this, be with should be noted that, in the present invention, no matter be the activity analyzed by performing HRV or learnt autonomic nervous system by the change observing the physiological signal affected by autonomic nervous system, during execution physiological feedback program, all relevant information is supplied in real time user by this information provider unit, to carry out the foundation of mental regulation as user, such as, the result that can HRV be provided in real time to analyze, heart rate, electrodermal activity situation, and/or limbs end slightly variations in temperature etc., and, the information provided easily is not limited to only a kind of, various selection can be had.

Analyze for real-time HRV, because HRV analysis analyzes heart rate sequence in a period of time, therefore, the carrying out that real-time HRV analyzes is implemented by the concept of traveling time pane (Moving Window), that is, first determine one computation time section, such as, 1 minute or 2 minutes, afterwards, by the continuous mode that this time section is passed backward, such as, within every 5 seconds, calculate once, just obtain HRV analysis result sustainably, such as, within every 5 seconds, obtain a HRV analysis result, thus the object that real-time HRV analysis result is provided is realized, in addition, also the concept of weighted calculation (weighting) can be adopted, moderately increase comparatively close to the calculated specific gravity of the physiological signal of analysis time, real-time physiological situation is more pressed close to allow analysis result.

Then, refer to Fig. 2, its display is according to the schematic diagram of an embodiment of blood pressure management device of the present invention, in this example, this physiological signal sensing unit is embodied as a finger-worn type optical sensor 11, to detect the continuous pulse wave of user, so, in this case, the heart rate sequence of user is learnt by measured continuous pulse wave, and just can HRV analysis be carried out after obtaining heart rate sequence, and then learn the activity of autonomic nervous system, or, also sympathetic nerve and parasympathetic active growth and decline are known by inference by observing heart rate, at this, though for being arranged at the finger folder form optical sensor of finger tip shown in figure, but also may be embodied as with other forms and be arranged on hands, such as, be embodied as ring form, the belt body being surrounded on dactylus or the form etc. of the left knee being located in finger, and, also that position optical sensor being arranged at finger is not limited to.

In addition, as shown in Figure 3, optical sensor 12 also can be embodied as ear and wear form, the same heart rate sequence learning user by measured continuous pulse wave, and HRV analysis is carried out after obtaining heart rate sequence, and then learn the activity of autonomic nervous system, or, also know sympathetic nerve and parasympathetic active growth and decline by inference by observing heart rate.At this, though for being located in the earclip type optical sensor on ear-lobe shown in figure, but also may be embodied as and be arranged on ear or its contiguous region with other forms, such as, be located on auricle, earplug or be hung on the first-class form of ear, and the position of contact is also unrestricted, such as, near the intersection that can contact ear-lobe, the inner face of auricle or the back side, auricle and head capsule, e.g., tragus (tragus) vicinity, in auditory meatus mouth or auditory meatus, and/or near mastoid (mastoid) after ear etc., therefore, not restriction.

At this, be with should be noted that, although blood pressure management device shown in Fig. 2-3 is all the form that housing 10 separates with arm-rest belt 14, but it is not limited, also the form that housing 10 is carried by arm-rest belt 14 can be embodied as, such as, being arranged at the position etc. of upper arm, forearm or wrist, is all enforceable mode.

Such as, moreover as illustrated in figures 4-5, this optical sensor 13 also can pass through arm-rest belt 14 and is arranged at upper limb, wrist, upper arm, or on forearm, and adopt the advantage of this kind of mode to be, after arm-rest belt completes around the action of limbs, the setting of optical sensor also completes simultaneously, has more convenience.

Fig. 4 A-4B illustrate the housing 10 when blood pressure management device be by arm-rest belt 14 carry time, optical sensor 13 depends on the possible case on arm-rest belt.In Figure 4 A, this optical sensor 13 is arranged in arm-rest belt 14, therefore in this case, this arm-rest belt can have a light-permeable part in the position of this optical sensor relative, the light sent to allow optical sensor passes through, at this, this optical sensor can adopt the light of various wavelength, such as, visible ray or black light can be utilized, if HONGGUANG and infrared ray (IR) etc. are all spendable wavelength band, therefore, this can pass through part and refers to the part formed by the material by visible ray and/or black light, or the part of hollow out, not restriction.

When reality is implemented, this optical sensor 13 of Fig. 4 A can be embodied as the surface being combined in housing 10, or to be separated with this housing 10 and to be electrically connected to the circuit in housing 10 through connecting line, in addition, relation between this optical sensor from arm-rest belt also can have and different arranges selection, such as, this optical sensor can be embedded on the inner surface that this arm-rest belt contacts with upper limb, or it is inner to be arranged at this arm-rest belt, that is in arm-rest belt pouch, or position is between this housing and this arm-rest belt etc., therefore, can change according to actual demand.

In addition, optical sensor 13 also can pass through a dependence structure and is arranged on arm-rest belt 14, and such as, Fig. 4 B shows the situation utilizing magic tape 15, or, be embodied as and be arranged on arm-rest belt through the mode of sandwiched, as shown in Figure 4 C, or, also can utilize the mode of magnetic-adsorption and allow optical sensor adhere on arm-rest belt, such as, can utilize across arm-rest belt two parts that magnetic is attracting each other, one of them parts is arranged on housing or arm-rest belt inside, to attract another parts carrying this optical sensor through magnetic force, and two parts can be embodied as both all has magnetic, or parts have magnetic force, and another parts can be magnetically attracted, not restriction, at this, magnetic force can arrange magnetisable material through the inside in parts, or directly make parts by magnetisable material and reach, in addition, similarly, the material attracted by magnetic force also can be arranged at components interior or in order to forming member.

Further, optical sensor as shown in figures 4 b-4 c, also can be embodied as and can separate with housing, only reconnecting whenever necessary, in addition, extending except utilizing connecting line except the situation of housing, also can be embodied as the mode adopting wireless connections, thus, the setting position of optical sensor can be more free.

Moreover, Fig. 4 D is then that display light sensor 13 is embodied as integrally formed situation with housing 10, and through the design of structure, this optical sensor 13 can be arranged between arm-rest belt and limbs around time on limbs at arm-rest belt, to carry out the acquisition of signal, and alternatively, this optical sensor also can be embodied as integrally formed with this housing and protrude from outside arm-rest belt, as shown in Figure 4 E, thus, this optical sensor only can be adjacent to limbs by arm-rest belt around the action of limbs, but is not folded between arm-rest belt and limbs, therefore, various possible embodiment is had.

Further, also detachable form can be embodied as between this optical sensor 13 and this housing 10 shown in Fig. 4 D-4E, such as, through electric connector, or through mechanical bonding structures, therefore when using, can be separated from housing, and at this, in particular, this optical sensor also can be embodied as and only carry out mechanical bond between this housing, and acquired signal is then through wireless mode and transmits.Therefore, various possibility can be had, not restriction.

So, when housing be carried by arm-rest belt time, this optical sensor 13 can not be embodied as and combine with this arm-rest belt and/or this housing, not restriction, only need can complete the setting of extracting needed for physiological signal while arm-rest belt is surrounded on limbs.

On the other hand, when housing 10 is embodied as the situation be separated with arm-rest belt 14, this optical sensor 13 only can be arranged on arm-rest belt, such as, can adopt as shown in figs. 4 a-4 c depend on form, directly be arranged on arm-rest belt, or depend on inside arm-rest belt through devil's felt, clip or magnetic force, namely 5th figure shows the situation that optical sensor is located in arm-rest belt edge, and, similarly, wired or wireless connection can be embodied as, and when adopting wired connection, as an example, electric connection line also can be hidden in the gas tube of arm-rest belt.Therefore, various forms can be embodied as on demand, not restriction.

And, in particular, only need through the design of structure, this optical sensor 13 also can be embodied as and can take off on this arm-rest belt or housing and be arranged at other positions of health, such as, and finger, ear etc., thus, just can change setting position according to actual service condition, have more convenience.

At this, be with should be noted, when optical sensor is embodied as wrist freely, forearm, or when the position such as upper arm obtains physiological signal, compared to penetrating mode, being preferably and adopting reflection mode to measure, preferably signal can be obtained.

In addition, this optical sensor, except in order to detect pulse change and then to obtain except heart rate, also can obtain other many physiologic informations about cardiovascular system, such as, blood oxygen concentration, blood volume changes etc., for example, can obtain different blood physiology information by the quantity of adjustment luminous source, such as, when having two luminescence components, just can obtain the information of blood oxygen concentration, more information thus can be provided to give user.

Moreover, electrocardioelectrode also can be utilized to measure electrocardiogram, and then obtain heart rate sequence.And in the present invention, in particular, electrode is also embodied as wearable form, this is because, in the present invention, measure the heart rate sequence during Electrocardiographic main purpose is to obtain physiological feedback, therefore, must contact during whole physiological feedback between maintenance electrode and skin, and when this contact be realized by user positive force time, except causing user inconvenience because of long-time operation, usually also there will be the problem of electromyographic signal interference, so, for such situation, the present invention proposes and utilize wear structure to carry electrode, and by this wear structure the scheme of contact between maintenance electrode and skin, thus, the contact of user owing to need not exert a force between maintenance electrode and skin, therefore more can be absorbed in body and mind relaxing, also the interference of electromyographic signal is therefore allowed to be down in addition minimum, more be conducive to the electrocardiosignal obtaining high-quality, and analysis result more accurately.

As Fig. 6 namely show two electrocardioelectrodes be embodied as respectively wear structure by ear and with ear or ear near contact skin, and wear structure by finger and contact the situation of finger skin, provide the configuration allowing user easily naturally can carry out physiological feedback training; Alternatively, two electrocardioelectrodes also all can be embodied as by referring to wear structure and be arranged at the form on finger; Or electrode also can select to be embodied as the form that wrist is worn, can reach equally initiatively exert a force to user and reducing the effect that electromyographic signal disturbs.

At this, be with should be noted that, although the ear shown in figure wears the form that structure is ear-hang, but be not limited to this, also earplug can be embodied as, the various forms such as the ear clip being sandwiched in ear-lobe or the ear clip being sandwiched in auricle, and its contact position does not also limit, ear-lobe can be contacted, the inner face of auricle or the back side, near the intersection of auricle and head capsule, as, tragus (tragus) vicinity, in auditory meatus mouth or auditory meatus, and/or near mastoid (mastoid) after ear etc., or, also can be embodied as and utilize the mode of magnetic force and be attached on ear, for example, can utilize across ear two parts that magnetic is attracting each other, and electrode be arranged at two parts or the mode wherein on parts and reach, at this, two parts can be embodied as has magnetic, such as, through inside, there is magnetisable material, or itself be the mode of magnetisable material, or be embodied as by can by magnetic attraction material made by, for example, can be embodied as there is magnetic force by parts, and another parts can be magnetically attracted, or, may also be two parts to be all embodied as there is magnetic force, various enforcement possibility can be had, not restriction.

Similarly, refer to that wearing structure also can have different forms of implementation, such as, can be embodied as and be located in finger tip, be located in the left knee place of finger or pass through other forms such as fixing around the belt body of finger, and, be also not limited to that position contacting finger, therefore, can change to some extent according to actual demand, not restriction.

In addition, also be with should be noted, in configuration so, ear-wearing type electrode selectively wears Yu Zuoer or auris dextra, not restriction, but, learn after experiment, the setting position of another electrode has the impact of certain degree for signal quality, wherein, when another electrode is arranged at left upper extremity, the quality of the electrocardiosignal obtained is much better than the signal acquired by right upper extremity, therefore, when carrying out electrocardiosignal in the mode contacting ear and measuring, be preferably the skin of another electrode contact left upper extremity, such as upper arm, underarm, hands wrist, hands is slapped, the places such as finger, to avoid causing signal quality bad because electrode is arranged at right upper extremity, and then cause analyzing generation erroneous judgement.

Moreover, except the form of the above-mentioned electrode be incorporated on wear structure, also can being embodied as the form combined with the housing of device itself or arm-rest belt according to electrocardioelectrode of the present invention, with by realizing electrode contact around the action of arm-rest belt, need not exerting a force by user equally.

When electrode be embodied as combine with arm-rest belt time, according to a preferred embodiment of the present invention, similar above-mentioned optical sensor, electrode combines with this arm-rest belt by a dependence structure, for example, as shown in Figure 7 A, this depends on mechanism can be embodied as a pair corresponding adhesion elements, such as, and magic tape, lay respectively on electrode and arm-rest belt, to realize be combineding with each other between the two; Or as shown in Figure 7 B, this depends on mechanism also can be embodied as a fixture, combines with electrode, is arranged on arm-rest belt in the mode by sandwiched by electrode; Or, as seen in figure 7 c, can be pair of metal fastener, with while combination, realize electrical connection simultaneously.

Further, this dependence structure also can be embodied as has a housing, for accommodating circuit, for example, in order to avoid acquired electrocardiosignal is via connecting line induced environment noise, can process in advance in ate electrode when obtaining signal, such as, amplify, buffering, filtering, the processing of circuit such as digitized, to guarantee the definition of signal, now, just can circuit be placed in housing, also the contact force between electrode and skin is increased by the hardness of housing, accordingly, this housing also can be embodied as the structure with the ergonomics meeting institute contact site further, such as, meet the radian etc. of arm, therefore, not restriction.

And the cause also owing to utilizing this to depend on mechanism, therefore when user does not need to use electrocardioelectrode or when needing to clear up arm-rest belt or when needing to change electrode, such as, be replaced by the electrode of unlike material, just can easily electrode taken off on arm-rest belt and/or change.

At this, the electrode combined with arm-rest belt, can be connected to housing by external connection line, as shown in Figure 7A and 7B, or, when housing is carried by arm-rest belt, also can as seen in figure 7 c, it is hidden in arm-rest belt inside with interelectrode electrical connection, and utilizes the mode of snapping to be arranged at inside arm-rest belt, therefore, not restriction.

So, when reality is implemented, if the housing of device is when being carried by arm-rest belt, just can as shown in Fig. 8 A (adopting the connected mode of Fig. 7 A) and Fig. 8 B (adopting the connected mode of Fig. 7 C), allow be incorporated into electrode contact pressurized arteries and veins band on arm-rest belt around the skin of limbs, upper ear is coordinated to wear structure by the skin near another electrode contact ear or ear again, and complete the electrode configuration of measuring needed for electrocardiogram, or, if housing not by arm-rest belt carried time, as shown in Fig. 8 C (adopting the connected mode of Fig. 7 B), also can coordinate and refer to wear structure and make the mode that another limbs of another electrode contact are pointed, therefore, not restriction.

In addition, when the housing of device be carried by arm-rest belt time, if electrode can be arranged on the housing when arm-rest belt is surrounded on limbs can contact on the position of skin, just provide by the action around arm-rest belt and allow the positive force of electrode contact arm skin, the interference of electromyographic signal can be reduced equally.

In this case, according to the structure of housing of the present invention, as shown in Figure 9 A-9C, be embodied as, on the surface be combined with arm-rest belt, there is an electrode bearing structure 112, to contact the skin of upper arm or forearm when arm-rest belt is surrounded on limbs, therefore, when electrode is arranged on this electrode bearing structure, electrode can complete with the contact of skin is just same in the action of installing arm-rest belt.

For example, as shown in Figure 9 A, this electrode bearing structure 112 can be embodied as the edge be positioned at close to arm-rest belt, and this arm-rest belt is embodied as in the position of this bearing structure corresponding and has an opening 114, therefore, just can realize the contact of electrode 113 between skin around the action of upper arm or forearm by arm-rest belt simultaneously, or as shown in Figure 9 B, also can be embodied as, among arm-rest belt, there is an opening 114, this electrode bearing structure 112 is then positioned at position corresponding thereto, moreover, as shown in Figure 9 C, this electrode bearing structure 112 is embodied as the both sides outer rim being positioned at arm-rest belt, the contact with skin just can be realized thus when not changing the structure of arm-rest belt, at this, although show both sides outer rim in figure all there is this bearing structure, but not limitedly, also can be embodied as and only be arranged at one-sided outer rim.

And further, this electrode bearing structure also can be embodied as tool contractility, such as, realize by adopting telescopic mechanism, or adopt the mode of tool elastic material, to adapt to the change that aeration period may occur, also guarantee the stability of electrode and skin Contact.

And, be with should be noted that, although this electrode bearing structure can be embodied as protruding form as shown in the figure, but be not limited to this, visual housing is different from the combination between arm-rest belt and change to some extent, such as, can also be the bearing structure with surface of shell equal height, only need the contact that can be able to realize when arm-rest belt is surrounded on arm between electrode and skin, not restriction.

Therefore, as shown in Figure 10, when an electrode be arranged at surface of shell and by around arm-rest belt contact by around the skin of limbs time (shell structure as shown in Figure 9 C), as long as coordinate upper ear to wear structure by the skin near electrode contact ear or ear again, the electrode configuration of measuring needed for electrocardiogram just can be completed.Certainly, also can coordinate and refer to wear structure and make the mode that another limbs of another electrode contact are pointed, therefore, not restriction.

Moreover, according to blood pressure management device of the present invention also by measure electrodermal activity and learn autonomic nerve be active in physiological feedback during change, as Figure 11 shows the situation in the change arranging two electrodes and detection of skin electrical activity on hand, or, also learn by measuring acral variations in temperature autonomic nerve be active in physiological feedback during change, as shown in figure 12.

Further, in the wear structure that electrocardioelectrode is set, also optical sensor can be set up, such as, be arranged at finger and wear structure or ear is worn in structure, therefore, by measured electrocardiosignal and pulse wave, just can show that pulse wave reaches the time needed for the sense position of optical sensor from heart, namely so-called pulse wave passing time (Pulse Transit Time, PTT), and due to PTT with affect blood pressure height arteries hardness relevant, therefore just by PTT and arterial blood beginning pressure value between specific relation and calculate the pressure value of reference, thus, the blood pressure trend that just can user be provided during physiological feedback real-time, in addition, similarly, also diverse location can be arranged at by by optical sensor, such as, ear and finger, and obtain same information by the time difference of calculating two place pulse wave transmission.

And those skilled in the art all know, if for calculating corresponding pressure value by PTT, still need to utilize standard blood measuring device to calibrate indispensablely, and have the function of being carried out blood pressure measurement by arm-rest belt due to device according to the present invention simultaneously, therefore, this calibration actions can directly easily be completed by same device, and user obtains the warming up of real-time pressure value during can being implemented in physiological feedback in naturally operating.

In addition, in particular, because the present invention possesses the function of being carried out blood pressure measurement by arm-rest belt simultaneously, therefore, when combination can obtain the physiology sensing element of the physiological signal affected by autonomic nerve, user can be provided in real time to be relevant to the information of blood pressure trend at physiological feedback training period according to blood pressure management device of the present invention.

Only need before physiological feedback training starts, by Measure blood pressure and the step obtaining physiological signal, obtain initial pressure value and physiological signal respectively, and perform measured by physiological signal and this initial pressure value between a calibration procedure, thus, just now measured physiological signal can be considered as being the reference value relative to this initial pressure value, then, after starting to carry out physiological feedback program, only the physiological signal continuing to obtain and this reference value need be compared, just can learn the variation tendency being relevant to pressure value, at this, this physiological signal can be, but do not limit, electrodermal activity, limbs end slightly temperature, heart rate etc.

For example, if the physiological signal detected is electrodermal activity, then only need before physiological feedback program start, obtain pressure value respectively and carry out EDA detection (such as, present with resistance value or electric conductivity value), and this numerical value is considered as a reference value, afterwards, can reduce because sympathetic activity increases based on resistance value, and sympathetic activity increase represents vasoconstriction increase, blood pressure rises, therefore, and just can during physiological feedback, by the rising of resistance value that records in real time or decline, and the information of the variation tendency providing user to be correlated with blood pressure.

In addition, know by inference except blood pressure trend except direct with the change of acquired physiological signal, as previously mentioned, real-time HRV analyzes also can in order to as the basis providing similar information, or aforesaid PTT equally also can be used for knowing blood pressure trend by inference, so there is no restriction.

And, because the physiological situation of human body is at any time in change, therefore, by the blood pressure measurement before each physiological feedback training, just naturally can complete recalibration, and obtain meeting the relation between the physiological signal of physiological situation instantly and pressure value.

When using above-mentioned various sensing element to carry out physiological feedback training, the form of implementation of this information provider unit can have various possibility, such as, can be embodied as and wear structure with ear, refer to that wearing the parts such as structure, housing or arm-rest belt combines, not restriction, in addition, information is also exported to external device (ED) by wired or wireless transport module by this information provider unit, therefore, various enforcement can be had to select, not restriction.In addition, provide the mode of information also not limit, present by modes such as audition, vision, senses of touch, such as, sounding module, vibration module and/or display module and/or light-emitting component etc. can be embodied as.

In a preferred embodiment, when with ear wear structure in conjunction with time, due to close with ear, therefore be preferably and be embodied as sounding module, enable voice directly enters ear, provides preferably confidentiality, or, wear structure due to this ear and can contact skin, therefore also vibration module can be embodied as, or, also can be embodied as the display module extended at the moment and/or light-emitting component etc., so, the form be applicable to can be selected according to actual demand.

In addition, the content of information that this information provider unit provides does not limit equally.For example, can be pressure value change or the variation tendency being relevant to blood pressure; Can be measured physiological signal, such as, heart rate, skin resistance, end limb temperature etc.; Can be the analysis result of physiological signal, such as, HRV analysis result; Can be the comparative result with desired value, such as, skin resistance, end limb temperature etc. be relative to the gap of desired value, and the gap of HRV analysis result and desired value; Or also can be the autonomic nerve information of user, such as, sympathetic activity is suppressed and/or parasympathetic nervous activity increases, therefore, not changing on an equal basis and to some extent of the difference providing the content of information can comply with measured physiological signal, user demand, not restriction.

In addition, this information provider unit provides the mode of information also to have various selection in physiological feedback training period, for example, when information is provided when utilizing visual manner, can be embodied as and utilize word and the real-time change showing physiological signal, the real-time analysis result of physiological signal, and the real-time comparative result between desired value, and/or the autonomic nerve information of user, mental and physical is adjusted, to reach targeted physiological condition gradually by understanding the real-time physiological change situation of self to be allowed user by such mode; Or, alternatively, also can be embodied as and utilize the change of figure, luminosity, optical flare frequency etc. and the gap between desired value be supplied to user, comparatively loosen because desired value represents body and mind usually, stable physiological situation, therefore, when more close to desired value, can utilize that graphic change eases up, luminosity diminishes or flicker frequency is slack-off etc. that mode represents, and gap when between desired value larger time, just represent that the body and mind tensity of user is higher, the modes such as graphic change is strong, luminosity becomes large or flicker frequency accelerates just can be utilized to represent.

When information is provided when utilizing audible means, above-mentioned various information can be provided equally, such as, by the mode of voice reminder allow user learn the real-time change of physiological signal, the real-time analysis result of physiological signal and/or and desired value between real-time comparative result etc.; Or, also show by the frequency of sound and/or volume change and gap between desired value, such as, volume is larger and frequency higher expression user mental and physical is more nervous, larger with the gap of desired value, volume is less and frequency is lower, represents that user more loosens, more close to desired value.

When information is provided when utilizing tactile manner, can be embodied as and utilize alerting by vibration whether to reach target zone, or also can by produce the interval of vibration signal and/or the power of vibration etc. and representative and whether reach target zone and/or and desired value between gap, such as, can when exceeding target zone, send vibration and remind user to need to loosen, or also can be, represent that user mental and physical is more nervous by vibration is stronger and vibration interval is shorter, larger with the gap of desired value, vibrate more weak and vibration interval is longer, represent that user more loosens, more close to desired value.

At this, be that no matter used sensing element why with should be noted that, and no matter detected physiological signal why, the information providing formula of this information provider unit is neither restricted.

In the conception of the present invention's another aspect, also carry out physiological feedback by the mode of respiratory daoyin, to reach the effect affecting autonomic nerve activity.This is because, breathe except controlling by autonomic nervous system, also directly can control by sense of independence, wherein, breathing is increase parasympathetic nervous activity during expiration to the impact of autonomic nervous system, and intake period increases sympathetic activity, therefore existing much research is pointed out, sympathetic nerve and parasympathetic balance can be changed by controlling breathing.

According to research contents, breathing rate, tidal volume, and during exhaling/intake period ratio be all the factor of the sympathetic and parasympathetic nervous activity of impact, wherein, speed is slack-off reduces orthosympathetic activity, speed accelerates, and sympathetic activity can be made to increase, for example, the breathing rate of general adult about drops in the scope of 10-18 time per minute, when the speed of breathing can be reduced to the scope of 5-8 time per minute, can contribute to increasing parasympathetic nervous active, in addition, when exhale during/intake period ratio increase time, that is, time during there is expiration longer for intake period, parasympathetic activity can obtain lifting equally.Therefore, in people's physical ability with under the prerequisite realizing control breathing, really sympathetic nerve and parasympathetic active balance is changed by the mode of Autonomous Control respiratory activity, and then improve because autonomic nerve is unbalance or sympathetic activity crosses the abnormal situation of high caused blood pressure, and reach the object of regulation and control blood pressure.

So, in the present invention, namely be by providing the respiratory daoyin signal having and be conducive to the breathing pattern adjusting blood pressure, such as, drop on the breathing rate of 5-8 time per minute that can reduce sympathetic activity, and/or can under the prerequisite of general breathing, during the expiration increased, and provide the mode of giving user by this information provider unit, adjust breathing to allow user can follow this changing pattern, and then realize the effect of adjustment blood pressure.

Wherein a kind of selection of this respiratory daoyin signal is, one fixing steering signal is provided, to impel user, breathing is adjusted to identical with it, and reach the effect of adjustment blood pressure by this, at this, this fixing steering signal can be, such as, contribute to the breathing rate reduced blood pressure, such as, 8 times per minute, or allow exhale during/intake period ratio increase guiding etc., not restriction, and multiple fixing steering signal can be provided, such as, 7 times per minute, per minute 6 times or per minute 5 inferior, and allow user select to meet the steering signal of self-demand voluntarily.

Another kind of selection is then, one gradual change steering signal is provided, and allow the breathing of user tend to gradually desirable breathing rate and exhale during/intake period ratio, for example, this gradual change steering signal may be embodied as and provides breathing pattern slack-off gradually, user is allowed to adapt to gradually, discomfort is caused to avoid speed rapid drawdown, such as, in 1 training section of 15 minutes, within 5 minutes, provide the speed of 10 times per minute above, the middle speed providing 8 times per minute for 5 minutes, and in the end 5 minutes provide the speed of 6 times per minute, in addition, also can be embodied as and increase between respiratory period gradually, such as, in 1 training section of 15 minutes, during within 5 minutes, providing expiration above/intake period ratio be the guiding of 1:1, the middle ratio that provides for 5 minutes is the guiding of 2:1, and within last 5 minutes, provide ratio to be the guiding of 3:1.

Further, if the upper physiological signal sensing unit that uses of collocation is to detect the physiological signal that can react respiratory variations again, user can learn whether the breathing of oneself conforms to respiratory daoyin signal, and the breathing of adjustment in real time oneself, and, if after through one section time, such as, after continuing for some time in training with respiratory daoyin once, or after repeatedly carrying out respiratory daoyin training, still feel to catch up with steering signal, user just can select the another kind of steering signal that can reach closer to physiological condition instantly, to avoid the situation upsetting breathing in order to meet steering signal on the contrary.

Moreover, the above-mentioned acquired information being relevant to breathing pattern, also can be used as the foundation of this respiratory daoyin signal of adjustment, thus the dynamic steering signal giving user and can adjust in real time is provided, namely, by the breath state of user obtained in real time, to learn why and/or whether breathing rate drops in the speed range being conducive to reducing blood pressure, and dynamic conditioning steering signal according to this, and allow user can reach the effect of respiratory daoyin training in the most comfortable mode.

For example, in a preferred embodiment, when recording breathing and having dropped in the default speed range being conducive to reducing blood pressure, such as, during lower than 8 times per minute, namely allow user breathe voluntarily and do not guide, only go beyond the scope at discovery breathing pattern, such as, time too fast, just guide; In a further preferred embodiment, the breathing rate that steering signal orders about user in the mode that section changes is slack-off, if and after guiding speed is slack-off in a special time, when finding that user cannot follow the rhythm of steering signal, then return to the respiratory daoyin speed of last section, and again slack-off after a special time, and by repeating program so, the breathing head for target breathing pattern of user just leniently can be guided.Therefore, can change to some extent according to user physiological status instantly or the demand of reality, and then various dynamic guide mode is provided, not restriction.

Moreover, when respiratory daoyin training is with the use of physiological signal sensing unit, also can be embodied as further, as previously mentioned, detect the physiological signal changed because breathing affects autonomic nerve, to provide the information of relevant autonomic nerve activity at respiratory daoyin training period, and whether breathing adjustment is to the movable impact effect causing expection of autonomic nerve to allow user know, such as, the sympathetic activity decline contributing to blood pressure and reduce whether is achieved.

For example, this information provider unit is while providing this respiratory daoyin signal, also relevant heart rate can be shown in real time, electrodermal activity, the information of acral temperature etc., and/or the information of the synchronicity of the related breathing being calculated by frequency spectrum and obtain and heart rate, therefore, user just can learn the impact of breathing and adjusting and causing for autonomic nerve in real time, such as, whether parasympathetic activity obtains lifting, or whether orthosympathetic activity reduces, thus, the physiological feedback program of carrying out with respiratory daoyin signal of can making concessions has more efficiency.

When reality is implemented, namely as before, just, this information provider unit outside the information providing relevant physiological signal, can export respiratory daoyin signal, for the foundation that user self is breathed as adjustment simultaneously.

At this, when providing this respiratory daoyin signal, as previously mentioned, this information provider unit can be embodied as and the form being worn on user parts with it and combining, the form that also can combine with the operation-interface of device, not restriction, and it provides the mode of this steering signal also to have various selection, such as, vision can be adopted, the mode of audition and/or sense of touch guides, also unrestrictedly.The selection of visual guidance includes, but not limited to graphic change, text importing, luminosity changes, and/or cresset change etc., be all suitable mode, for example, the pattern that meets respiratory variations pattern can be utilized on the display element and guide user and carry out air-breathing and feel elated and exultant; Or represent air-breathing by the number change of LED and feel elated and exultant; Or word can be utilized directly to inform, and user carries out air-breathing and feels elated and exultant.

In addition, when adopting the mode of audition guiding, selecting then to include, but not limited to sound variation and voice, for example, air-breathing can be represented and change of feeling elated and exultant by the power of sound; Or represent air-breathing by different sound kinds and feel elated and exultant, and allowing user follow, such as, tweedle, sound of sea wave, different music track etc.; Or also can be informed user this carries out air-breathing or feels elated and exultant by voice, such as, when just starting to carry out respiratory daoyin training, " air-breathing " and " feeling elated and exultant " voice by meeting respiratory variations pattern indicate and guide the breathing pattern of user, and when detecting that the breathing of user has met the changing pattern for reaching, namely inform that user " continues to maintain present compressing speed ", and stop the voice instruction that " air-breathing " " feels elated and exultant ".Therefore, various selection can be had, can change, not restriction according to the demand of actual enforcement.

Moreover, when adopting the mode of tactile guidance, then be preferably the form that combined by the parts of physical contact with the user and the change of vibration is provided, such as, with arm-rest belt, the parts such as the housing carried by arm-rest belt or the wear structure of physiological signal sensing unit combine, and as the variation pattern vibrated, then do not limit equally, such as, can be embodied as and utilize vibration signal to the expiration reminding user correct and/or inspiration start time point, or only find the breathing pattern of user depart from default target guiding signal too much time just produce vibration and guide.

At this, advantageously, when adopting the mode of audition and/or tactile guidance, user can to close eyes in respiratory daoyin training period tool, more contributes to physical relaxation and breathes adjustment.

In addition, the time of implementation of respiratory daoyin training, also can be changed according to the actual demand of user, such as, fixing several time spans can be provided, such as, 10 minutes, 15 minutes or 20 minutes, select voluntarily for user, in addition, also can be embodied as the physiological situation according to training period and change, not limiting equally.

In addition, in a preferred embodiment, this respiratory daoyin signal (can be fix, gradual change or dynamic steering signal) also can be embodied as via this information provider unit and wire/wireless transport module after exporting this external device (ED) to, such as, smart mobile phone, panel computer, intelligent watch etc., by this external device (ED), this respiratory daoyin signal is supplied to user again, carries out respiratory training for user.

And especially, in a further preferred embodiment, this respiratory daoyin signal is then be embodied as to be produced by this external device (ED) and to be supplied to user, now, this external device (ED) can receive the information of the associated user breathing pattern acquired by this physiological signal sensing unit further from this information provider unit, to be supplied to user while providing this respiratory daoyin signal, or be used as the foundation of this respiratory daoyin signal of adjustment, in addition, the information storage of the associated user breathing pattern of required reception also can get off by this external device (ED) further, using as reference when watching record afterwards.

At this, when this physiological signal sensing unit is embodied as detection breathing, this physiology sensing element can be embodied as the sensor that general common on the market detection is breathed, for example, be located at the respiratory movement sensing element of chest and/or abdominal part, to experience the body cavity fluctuating of breathing and causing, such as, RIP bandage (Respiratory Inductance Plethysmography (RIP, respiratory inductive plethysmograph) effort belt), and piezoelectricity breathes bandage (piezo respiratory effort belt), be arranged at the respiratory air flow pipe of nasal airways, to detect the change of respiratory air flow, and the thermal sensor be arranged between mouth and nose, to respond to the variations in temperature etc. of respiratory air flow.

As shown in figure 13, blood pressure management device according to the present invention is configured with a respiratory movement sensing element, and such as, piezoelectricity breathes bandage sensor or RIP bandage, to obtain the breath signal of user at respiratory daoyin training period.When carrying out respiratory daoyin training, bandage is arranged at chest or abdominal part by user, loosen mood to start to breathe, and adjust the breathing of oneself according to the guiding of the respiratory daoyin signal (and being relevant to the information of the physiological signal changed because of breathing) on display element or sound, and after continuing for some time, complete respiratory daoyin training process.

At this, as shown in figure 14, also two bandages can be embodied as, unrestricted, and, point out owing to also there being research, ventral breathing is adopted to contribute to increasing parasympathetic activity, therefore, when use two bandages, by being arranged at the mode of chest and abdominal part respectively, whether what carry out with regard to distinguishable user is ventral breathing.

Alternatively, also Ke Tong Over observes blood volume (blood volume) fluctuation of breathing and causing, or learns the change of breathing by measuring heart rate.First, due to the fluctuation that can cause blood volume with air-breathing of exhaling, such as, can in tremulous pulse, vein, and observe in blood capillary, so, by using optical sensor just can penetrate or the light signal that reflects from the blood of experimenter and obtain the information that relevant blood volume fluctuates by analyzing, and then learn the Respiratory behavior of user; Moreover, because heart rate controlled by autonomic nerve, therefore breathing can make heart beating occur change because having an impact to autonomic nervous system, namely, so-called sinus arrhythmia (Respiratory Sinus Arrhythmia, RSA), generally speaking, intake period, can make to palpitate quickly, and then makes heart beating slow down between respiratory period, therefore learns respiratory variations by observing heart rate.So, just can adopt the sensor that can obtain heart rate sequence foregoing, such as, optical sensor, electrocardioelectrode etc., and the information that respiratory variations is provided in respiratory daoyin training period.

In addition, reaction (Relaxation Response) is loosened because the amplitude strengthening RSA contributes to triggering, remove the pressure of accumulation, and reach the effect of raising parasympathetic nervous/sympathetic activity ratio, therefore, by observing the changes in heart rate pattern of user, and when heart rate starts to accelerate, inform that user can start air-breathing by guiding, and when heart rate starts to slow down, inform that user can start to feel elated and exultant by guiding, to reach the effect increasing RSA amplitude, also reach the object of adjustment blood pressure.In addition, the size of amplitude acquired by RSA crest and trough, that is, in a breathing cycle, difference between the maximum of heart rate and minimum, can be relevant to the active height of autonomic nerve, therefore, this information can be provided in real time equally and give user, to regulate the basis of physiological activity as user.

Further, also can be as shown in figure 15, beyond respiratory movement sensing element, upper finger-clipped optical sensor is coordinated to obtain heart rate sequence again, and by such sensor setting, except can because obtaining heart rate more, and confirm that respiratory daoyin is trained outside the impact that causes further, because between breathing and heart rate, harmony and synchronicity represent heart beat rhythm that is more orderly and that coordinate preferably, namely, human body is in compare and loosens, stable state, therefore, also can breathe whether harmonious and synchronous with between heart rate and in order to judge the effect that respiratory daoyin is trained and/or as providing the information of giving user in real time by analysis, for example, such as, frequency-domain analysis can be carried out to heart rate sequence, represent that when frequency spectrum is more concentrated synchronicity is higher between the two, or the phase contrast that also can to calculate in time domain between the two, when phase contrast more hour represents that synchronicity is higher between the two, or, alternatively, ear also can be utilized to wear structure and refer to wear vibrational power flow electrode and obtain electrocardiosignal, then coordinating upper bandage to obtain breath signal, also can reach same effect, or, also can set up electrocardioelectrode contact skin inside bandage, obtain electrocardiosignal.Therefore, can change according to user actual demand and use habit, not restriction.

Should be noted at this, although above-mentioned example is specifically described the mode of enforcement, but the present invention is not limited to the occupation mode in single instance, can to merge between Multi-instance or part merges use, or mutually exchange use between Multi-instance, therefore, above-mentioned example is only some combinations in numerous possible embodiment, and this area knows that the knowledgeable can carry out modifying still not de-category of the present invention according to this usually.

Moreover, conception according to a further aspect of the present invention, in order to the effect allowing user can learn its physiological feedback carried out in real time, blood pressure management device according to the present invention also provides an operating process, can assess training effect immediately to allow user after physiological feedback has been trained.

Figure 16 shows the operational flowchart according to blood pressure management device of the present invention.When user uses according to blood pressure management device of the present invention, first arm-rest belt is surrounded on hands arm, if and when possessing physiological signal sensing unit, set physiological signal sensing unit, such as, electrocardioelectrode or optical sensor etc., afterwards, after pressing start key, blood pressure measurement starts immediately, arm-rest belt carries out inflating and exitting, user is given to obtain pressure value and to show, then, start physiological feedback program, and during physiological feedback, according to the difference of the program of carrying out and measured physiological signal, user can be provided to be relevant to the information of measured physiological signal, the information of relevant autonomic nerve, the trend of relevant blood pressure trend and/or respiratory daoyin signal etc., physiological feedback is performed according to this to allow user, and after training terminates, device starts another blood pressure measurement immediately, that is, arm-rest belt carries out inflating and exitting again, to obtain the pressure value after physiological feedback training, thus, as long as the pressure value before comparing training and after training, user just can learn the effect that physiological feedback is trained.

Therefore, by such flow process, user can natural DIYU overall flow terminate after learn whether the training of performed physiological feedback reaches the object of expection immediately, quite convenient, and, flow process so also makes pressure value change, physiological feedback training process and the relation etc. between pressure value and training all positively go on record, and is conducive to long-term tracking and managing.

Further, above-mentioned operating process also can be embodied as the mode by guiding and realize, such as, by this information provider unit, or this external device (ED) performs a program, and provide in the mode of audition or vision and guide instruction, and user only need be followed instruction and just easily and naturally can be completed physiological feedback and train and learn the effect that training realizes.

For example, first, after device is activated, can first indicate user that arm-rest belt is surrounded on a upper limb body, if and when possessing physiology sensing element, carry out the setting of physiology sensing element, afterwards, blood pressure measurement is carried out by arm-rest belt, to obtain the pressure value before carrying out physiological feedback training, then, user is guided to start to carry out physiological feedback training, and during physiological feedback, according to the difference of the program of carrying out and measured physiological signal, user can be provided to be relevant to the information of measured physiological signal, the information of relevant autonomic nerve, the trend of relevant blood pressure trend and/or respiratory daoyin signal etc., to guide the carrying out of physiological feedback program, and after training terminates, user is then again indicated to utilize arm-rest belt to carry out blood pressure measurement, to obtain the pressure value after training.

At this, this operation guide mechanism presents mainly through the mode of voice, for example, by " please arm-rest belt be bind ", " blood pressure measurement please be start ", " please start to perform physiological feedback training ", " guiding please following screen is breathed ", " please again start blood pressure measurement " etc. and describe and remind user, with the complexity of reduction operation, and in a preferred embodiment, this is then sounding module by combining with ear-wearing type physiology signal sensing unit and realizes, such as, be embodied as the physiology sensing element of earphone forms, with the complexity that simplifies the operation further.

Or, alternatively, also the mode of screen display can be utilized to provide the guide of user operating procedure, or the mode of voice and screen display also can be utilized simultaneously to guide, in addition, external device (ED) also can be utilized further as the medium guiding operating process, such as, smart mobile phone, panel computer etc., therefore, not restriction.

And the basis so performing flow process easily is just, blood pressure management harness of the present invention has multi-functional, except the autonomic nerve that can detect user is movable, respiratory daoyin is provided, carry out HRV measurement and analysis, and outside the information etc. of synchronicity that regarding heart rate and breathing be provided, also blood pressure measuring function is had, so, user is in order to adjust blood pressure while performing training, in same device, just can confirm whether the object that blood pressure adjusts realizes, quite there is efficiency, and, in order to carry out physiological feedback training, user only need perform outside the action needed for blood pressure measurement, the action of physiological signal sensing unit is worn in extra increase, there is no complicated operation sequence, simply facilitate again.

Moreover, because the hardware device realized needed for blood pressure measurement and physiological feedback training has mass part to share, such as, control circuit, information provider unit etc., therefore under the prerequisite of multi-functional, more cost-effective.

At this, last result display can have various different mode, such as, the pressure value measured by before and after respiratory daoyin training can be shown simultaneously, or the difference etc. between display two pressure values, in addition, also can show the time span of training jointly, and allow user know the time length of training and pressure value change between relation, therefore, not restriction, is mainly to allow user understand the change of pressure value.

In addition, allow user complete blood pressure measurement and physiological feedback to train and except learning the flow process of training effect, blood pressure management device according to the present invention also has another notification mechanisms, as shown in figure 17 except above-mentioned simultaneously, when it can find that pressure value is too high after blood pressure measurement, such as, during higher than a preset value, user is reminded to carry out physiological feedback training, to carry out blood pressure adjustment, thus, user just then can carry out physiological feedback training naturally, quite convenient.

At this, the mode of prompting can have different selections equally, such as, screen display, cresset shows, sound or voice reminder, and/or vibrating alert etc., in addition, about the comparison preset value of hyperpiesia, can by user sets itself or the setting value following device itself, such as, the blood pressure standard of WHO, not restriction.

Moreover, refer to Figure 18, because HRV analyzes the information that can provide autonomic nerve, therefore, when the physiological signal acquired by the physiology sensing element that this physiological signal sensing unit possesses, when can obtain heart rate sequence according to this and carry out HRV analysis, then blood pressure management device according to the present invention just can be embodied as further, also physiological signal extraction is carried out while Measure blood pressure, with after blood pressure measurement terminates, except pressure value, also HRV analysis result is provided and give user, for example, by using optical sensor, electrocardioelectrode, and/or the physiology sensing element such as pressure transducer, and while blood pressure measurement, obtain the time series of user eartbeat interval, afterwards, again HRV analysis is carried out to this time series, to obtain the information about autonomic nerve activity by this.

Wherein, this HRV carried out analyzes can have different choice on demand, such as, frequency-domain analysis (Frequency domain) can be carried out, general power (the Total Power assessing overall heart rate variability degree is can be used to obtain, TP), high frequency power (the High Frequency Power of parasympathetic nervous activity can be reacted, HF), low frequency power (the Low Frequency Power that sympathetic activity or sympathetic nerve and parasympathetic nervous regulate and control result simultaneously can be reacted, LF), and the LF/HF (low high frequency power ratio) etc. of sympathetic/parasympathetic active balance can be reacted, in addition, also can after carrying out frequency analysis, the state distributed by observed frequency and learn the harmony analysis matrix that autonomic nerve operates, or, also time-domain analysis (Time Domain) can be carried out, and obtain the SDNN that can be used as the index of overall heart rate variability degree, can be used as the SDANN of the index of long-term overall heart rate variability degree, can be used as the RMSSD of the index of the overall heart rate variability degree of short-term, and can be used to R-MSSD, NN50 and PNN50 etc. of assessing high frequency closedown among heart rate variability degree.

And in this case, if when there is hypertension, just the association between hypertension and autonomic nervous system can be judged further by HRV analysis result, such as, whether be caused because orthosympathetic activity is too high or autonomic nerve is unbalance, quite convenient.

Afterwards, when analyze from HRV found that hypertension is relevant to autonomic nervous system time, except the information of this association is supplied to except user, user also can be reminded further to perform physiological feedback training, and again physiological signal is measured after physiological feedback has been trained, carry out HRV analysis, to learn whether the equilibrium condition of autonomic nerve is improved.

In addition, because the time of carrying out needed for HRV analysis is longer, therefore, also can as shown in figure 19, be embodied as when finding that pressure value is too high, such as, during higher than a preset value, then user is reminded to carry out HRV measurement, to judge that whether hypertension is relevant with autonomic nerve by HRV analysis result.

After blood pressure measurement and physiological feedback have been trained, according to blood pressure management device of the present invention, by built-in memorizer, the blood pressure measurement of user can be stored in real time and chronically, and record the process of user training simultaneously, therefore, by the record like this according to time sequencing, the alternate analysis result that the present invention can provide user to be different from independent blood pressure measuring device or physiological feedback training devices.

First, the most directly, compare with pressure value afterwards before execution training can be provided.By time of origin interior during record order, except learning the pressure value difference before and after secondary training as previously mentioned immediately, user also can trace back to the blood pressure before certain training, and the blood pressure after how many times training, the record of the training only needing comparison to experience, just clearly can know that the time span and number of times etc. of training bring impact to blood pressure.

For example, user can be selected some time points, such as, before not yet carrying out physiological feedback training, measured pressure value is worth as reference, then, carried out training just to compare with this reference value at every turn, such as, set and automatically produce comparative result by system, thus, user just can obtain clear and definite quantized values, such as, the relation between training cumulative frequency and blood pressure, this continues contributing to increasing user the power that carries out training.And because the effect of physiological feedback training has accumulative effect, long-term observation understands the impact that adjusts blood pressure of physiological feedback by more contributing to.

In addition, because the blood pressure of people in one day is different along with time and activity, therefore the reference value of Different periods can also be set, such as, the reference value in morning, noon, evening, allow the reference value of measured pressure value and close temporal proximity after physiological feedback training compare, avoid causing incorrect judgement; Or user also can freely be selected reference value and set up benchmark according to self-demand, carry out self the most helpful analysis, therefore, not restriction.

In sum, according to the blood pressure management device that can provide blood pressure adjustment and blood pressure measurement two kinds of functions of the present invention simultaneously, it is trained by physiological feedback and provides user to adjust the approach of blood pressure, and, during execution physiological feedback program, in order to obtain the physiology sensing element of the physiological signal being relevant to autonomic nerve activity, be be arranged at it user by the form of wearing, contact long-time and stable between physiology sensing element and human body can be provided, to obtain the physiological signal of high-quality, and, due to the blood pressure measuring function possessed simultaneously, also allow user can the effect that adjusts blood pressure of real-time confirmation physiological feedback, in addition, according to blood pressure management device of the present invention, also helping by providing respiratory daoyin signal user to perform physiological feedback program, effectively can reach the effect of adjustment blood pressure equally, in addition, by according to the physiological feedback training process of sequence of event and blood pressure measuring value, user easily can monitor the change of pressure value, and physiological feedback trains the impact brought blood pressure change, contributes to the object more effectively realizing adjusting blood pressure.
