Description
Technical field
The utility model relates to the monitoring equipment/device of a plurality of physiological parameters, particularly realizes the real-time continuous monitoring equipment/device of a plurality of key physiological parameters.
Background technology
The monitoring of physiological parameter, especially the monitoring that the key physiological parameters that reflects the cardiovascular system function is changed can be the user provides information feedback timely, so that understand its health condition.The statistics of American Heart Association shows that the annual whole world has 16,600, and 000 people dies from angiocardiopathy, and it has become the No.1 killer of harm humans health.The physiological parameter of reflection cardiovascular system function generally includes: heart rate, changes in heart rate rate, blood pressure, blood oxygen saturation and respiratory rate etc.By these physiological parameters are carried out daily monitoring, can make the angiocardiopathy that people early find, early treatment may cause serious consequence.The measurement of these physiological parameters will be finished by different instruments or device usually, that is to say, the measurement of each parameter all needs an independent device.Like this, not only increase user's expense, nor be convenient to daily use.
At present, great majority are applicable to that monitoring device used in everyday is to occur with the form of wrist-watch or other mancarried devices.This class watch style device mainly can provide the monitoring to heart rate.The user is by wearing the above-mentioned physiologic information that obtains that wrist-watch can be real-time continuously.But the information of the sign cardiovascular system function that this device can provide is comparatively limited, only is confined to provide the monitoring of heart rate information.And read information from wrist-watch, may hinder the ongoing activity of user in some occasion.
Other can provide the device of more sign cardiovascular system parameter, and usually volume is relatively large, cannot wear with oneself so that instant these physiological parameters that obtains.Therefore, exploitation is a kind of can wear with oneself and can interference-free provide the device of a plurality of cardiovascular system status informations just to seem particularly important in real time.
The user obtains the information of relevant reflection motion state by wearing glasses, and can find in the laid-open U.S. Patents as the technology of run duration, move distance and movement velocity etc.As United States Patent (USP) 4,526, a kind of spectacle motion time set that electronics shows that has is disclosed in 473.United States Patent (USP) 4,751,691,5,103,713 and 5,258,785 grades disclose relevant eyeglass design structure, the method for especially central display device.But above-mentioned patent has only provided how to realize the different approaches of Presentation Function on glasses, how not to use the physiological parameter that this structural design of glasses is monitored the sign physiological status and relate to.
United States Patent (USP) 5,585,871,5,813,990 and 6,431, propose in 705, not only can measure the information of motion states such as run duration, move distance and movement velocity by wearing spectacles, but also can measure the method for the parameter of temperature and this sign physiological status of heart rate.At United States Patent (USP) 5,585, in 871 and 6,431,705, heart rate measurement device is to be integrated in the project organization of glasses.Sensor is by contacting detected pressures to change or pulse wave with user's the temple or the bridge of the nose, thereby obtains heart rate information, and relevant information projects wearer's viewing area by the mode of fiber optic conduction afterwards.Since limited from above-mentioned two signals that the measuring position obtained, so above-mentioned choice of location is not suitable for the measurement of other physiological parameters.At United States Patent (USP) 5,813, in 990, the sensor clip that detects pulse wave can calculate heart rate by detected pulse number by calculating in one minute on user's ear-lobe.Employed pulse wave detection sensor is infrared photistor and photoelectric detector in this patent, detects pulse wave by transmission mode.
Though all can realize real-time rhythm of the heart continuously by above-mentioned three patents, the switch controlling signal of glasses but will be operated manually, thereby can not realize noiseless formula physiological parameter monitoring veritably.And, in the daily use of reality, only know that heart rate information is inadequate.The parameter of other reflection cardiovascular system state variation situations, as blood pressure, blood oxygen saturation and respiratory rate etc., it also is very important that the user is understood its health.But not having a kind of Wearable eyeglass device at present can carry out real noiseless real-time monitoring to a plurality of physiological parameters.
The utility model content
Technical problem to be solved in the utility model is to have proposed to use the numerical value that glasses or luntttes realize characterizing a plurality of key physiological parameters of cardiovascular system state.The wearer need not to intervene this monitoring device and can obtain the numerical value of above-mentioned physiological parameter in real-time continuous ground, thereby their daily routines are not hindered in daily use.
The technical solution adopted in the utility model provides a kind of glasses of monitoring the physiological system parameter, comprising: common Glasses structure is as the carrier of other elements; Be positioned at the bio signal gauge tap of described Glasses structure ad-hoc location, enabling signal to take place in the particular organisms signal that described bio signal gauge tap response user's body sends; Be adapted to be mounted to the sensor unit of the suitable measuring position of user's health, described sensor unit links to each other in wired or wireless mode with described bio signal gauge tap and begins to measure the suitable physiological signal of human body to receive and to respond described enabling signal; With the processor unit that is arranged in described Glasses structure, link to each other in wired or wireless mode with described sensor unit, receive from measuring of described sensor unit physiological signal and calculate described physiological parameter information.
Preferably, the nondestructive measurement of multinomial physiological parameter is realized by utilizing photoelectric sensor to detect the photoplethaysmography signal on ear in the utility model.The measurement of heart rate can realize by the time of calculating between the row photoplethaysmography signal waveform summit; The measurement of blood pressure can be by asking for the time delay between the two row photoplethaysmography signals, and promptly the pulse wave transmission time realizes; Thereby perhaps utilize the correction of upper arm blood pressure waveform to calculate pressure value from the photoplethaysmography signal waveform that ear obtains.The measurement of blood oxygen saturation can utilize the principle of pulse blood oxygen instrument to realize.The measurement of respiratory rate obtains by the photoplethaysmography signal is carried out filtering in certain frequency band.
Different with former device, by fixed light electric transducer on user's ear, this device also can be measured blood pressure, blood pressure change rate, blood oxygen saturation and respiratory rate etc. except measuring heart rate, changes in heart rate rate.Because the sensor volume is little, in light weight, can not cause too much influence to the volume and weight of whole device.
The utility model also comprises a control mode of carrying out the switch of physiological parameter measurement by bio signal.Because physiological parameter measurement of the present utility model utilizes glasses or luntttes to finish, thus the bio signal that is used for switch control all with near the resulting signal eyes for paying the utmost attention to.This mode can be exempted manual operation, really accomplishes noiseless formula measurement, can reduce the volume and weight of device simultaneously to a certain extent, and reduce power consumption.
Useful technique effect of the present utility model is: in order to realize monitoring a plurality of physiological parameters by Wearable device interference-free, the utility model proposes and use the measurement that glasses or luntttes realize characterizing a plurality of key physiological parameters of cardiovascular system state.Because the utility model utilizes bio signal as switch controlling signal, but not adopt traditional manual mode, thus the user by wearing glasses or luntttes just can really be realized complete glitch-free measurement, thereby remedied the deficiency of above-mentioned all devices.

In order to make this Glasses structure be applicable to daily routines, it must be firm, shatter-proof and light and handy.Eyeglass 113 can be selected lighter resin material for use, and mirror holder 112 and picture frame 101 can be selected the poly-third ethene injected plastics material for use.Sensor 105, battery 102, printed circuit unit 104 and 106, microprocessor unit 107, display unit 103 and phonation unit 114 can be placed in mirror holder 112.Be the weight of the whole glasses of balance, but circuit separated into two parts 104 and 106 are positioned over the left and right sides of mirror holder 112 respectively.And sensor 105, battery 102, display unit 103 and phonation unit 114 can be positioned over the left and right sides of mirror holder 112 according to the requirement of weight balancing respectively.Microprocessor unit 107 is except corresponding physiological parameter of calculated signals and storage data that utilization receives, and it also links to each other with voice unit (VU) 114 with display unit 103, the reception and registration of control information.
Circuit is except being placed in mirror holder 112, partly printed circuit unit 104 and 106 also can be placed on sensor array 115,116 and 117 to handle the physiological signal that obtains, comprise and amplifying and filtering, again from sensor array 115,116 and 117 in the wireless data transmission mode, passes to the printed circuit unit 104 and 106 that remainder places mirror holder 112, and allows microprocessor unit 107 carry out the calculating and the data storage of physiological parameter.
In addition, printed circuit unit 104 and 106, microprocessor unit 107, display unit 103, phonation unit 114, display unit 103 and information are inspected pattern 110, also can all be integrated in sensor array 115,116 and 117, to alleviate the weight of glasses, for the user provides more comfortable physiological parameter monitoring.
Function selecting and control module 109 can place on the spectacle frame 112, by button the use pattern of glasses are controlled.Obtain physiological parameter information as selecting with visual manner or with voice mode.Visual manner can obtain real-time information and upgrade, and voice mode can only obtain the information updating of discontinuity, can select the time interval of information updating during use voluntarily.Simultaneously, also can select only a certain designated parameter to be carried out information updating during use.Acoustic pattern also possesses warning function except being used for passing on the updated information.As a certain physiological parameter index has been preset a ultimate value when using, when this parameter surpassed preset value, system will provide alarm so.
The imaging mode of display unit 103 has multiple choices, and as LCD, LED and CRT etc., its detail can find in aforesaid United States Patent (USP).Equally, the concrete implementation detail that information is inspected pattern 110 also can find in aforesaid United States Patent (USP), repeats no more here.Phonation unit 114 can place on the spectacle frame 112 in nearly ear place or user's the cochlea (use earplug).
Sensor array 115,116 and 117 is made up of at least three photistors and three photoelectric detectors at least, and its particular location that contacts with ear 201 is shown in Fig. 2 a.In three photistors, one 115 top wavelength is selected in the infrared wavelength coverage, and following two 116 and 117 wavelength are selected in respectively in the wavelength coverage of infrared and ruddiness.Usually in infrared wavelength coverage, 940nm can be selected, and in the red light wavelength scope, 660nm can be selected.Corresponding photoelectric detector is to the light activated element in the above-mentioned wavelength coverage.Because ear 201 place's institutional frameworks are thinner, photistor preferably adopts transmission mode work, adopts this mode can obtain stronger signal.But also can adopt the reflection mode to work.Its detected signal is the photoplethaysmography signal, and this signal and heartthrob are synchronous, and therefrom the parameter of Ti Quing can reflect the health condition of cardiovascular system.
In the utility model, the sensor 116 that is positioned at the ear bottom can have different contact positions with 117 with ear.Because the photoplethaysmography signal is easier to be subjected to the motion interference of noise, we have made optimized choice to sensor array and ear position contacting.Position as the sensor among Fig. 2 a 117 is selected in the utility model, and its position is far away from face.Sensor 117 positions among Fig. 2 b are then nearer from face.We found through experiments, and are subjected to the motion The noise less from face position far away.Therefore in the present embodiment, the optimum seeking site of sensor 117 be from face position far away, and its position range is probably to be about 0.5～1.0cm from face.
The utility model is except that can be with the switch of manual mode by the button control physiological parameter measurement, and also the bio signal that can utilize health to send comes gauge tap.This design has reduced manual operation, has therefore reduced the interference of measuring the user.Also provide possibility simultaneously for reducing components consume and power supply power consumption.Because physiological parameter measurement of the present utility model utilizes glasses to finish, thus the bio signal that is used for switch control all with near the resulting signal eyes for paying the utmost attention to.
In preferred embodiment one, utilize the bio signal of pressure change signal as gauge tap, it obtains by a pressure transducer 105a and finishes.Pressure transducer 105a by device in mirror holder 112.The degree of tightness of mirror holder 112 is adjustable, contacts effectively with user's face to guarantee pressure transducer 105a.When the user carried out the opening and closing movement of eyes, the muscle of around eyes was tightened up, and pressure transducer 105a will obtain corresponding pressure change signal.This pressure signal just can be used as the control signal of switch through amplification, filtering and/or the amplification again of circuit unit 104 and 106, and glasses are started to measure one or more physiological parameters.
In preferred embodiment two, utilize the bio signal of electronystagmogram trace signal as gauge tap, it obtains by three electrode 105b and finishes.When eyes moved, the electric signal between cornea and the retina can change thereupon.In human body, this electric energy is generally 0.05 to 3.5mV, and the distance that the eyes of making peace greatly move is directly proportional.This electromotive force information is called as the electronystagmogram trace signal.As long as on user's face, just can obtain the electronystagmogram trace signal to five electrode pastes.By measuring this signal, just can estimate moving of eyes.During measurement, pair of electrodes is placed on the left and right sides of eyes, is used for measuring moving horizontally of eyeball; Another is used for measuring the vertical moving of eyeball to then being placed on the upper and lower of eyes, and remaining one is placed on forehead as the reference point.The concrete practice of the metering circuit of electronystagmogram trace signal is at document Automatic Detection and Operant Reinforcement ofSlow Potential Shifts, J.M.Siegel, M.B.Sterman and S.Ross, Physiology﹠amp; Behavior, 23,1979, have a detailed description among the 411-413, therefore, repeat no more here.In addition, it will be understood by those skilled in the art that the electrode of measuring reference signals can omit, and only adopt pair of electrodes can realize above-mentioned purpose to measure the electronystagmogram trace signal.Again, a ground connection can be arranged in the aforementioned pair of electrodes, therefore, only use an electrode also can record the electronystagmogram trace signal in the practice.
Because the utility model only utilizes a kind of mode of electrooculography signal as switch control, rather than the measurement of moving as eyeball, so only need three electrode 105b.A pair ofly be used for measuring electric signal, its laying method can be a level, also can be vertical, and an other conduct is with reference to point.These electrodes 105b is installed in mirror holder 112.The degree of tightness of mirror holder 112 is adjustable, contacts effectively with user's face to guarantee electrode 105b.With a pair of electrode 105b that places in a horizontal manner is example, as long as the user moves to left eyeball or move to right three times continuously, resulting electronystagmogram trace signal is through amplification, filtering and/or the amplification again of circuit unit 104 and 106, just can be used as the control signal of switch, glasses are started to measure one or more physiological parameters.With a pair of electrode 105b that places with vertical mode is example, as long as the user will move on the eyeball or move down three times continuously, resulting electronystagmogram trace signal is through amplification, filtering and/or the amplification again of circuit unit 104 and 106, just can be used as the control signal of switch, glasses are started to measure one or more physiological parameters.
Fig. 3 a, 3b are that the method synoptic diagram is put in two placements as measurement electrooculography signal electrode.In Fig. 3 a finding, a pair of be used for measuring electrooculography signal electrode 105b1 and 105b2 can be level be placed on temple 301 positions, and just be put in before the volume 302 as reference point electrode 105b3.In Fig. 3 b finding, electrooculography signal electrode 105b1 can be the vertical upper and lower that is placed on any eyes 303 with 105b2, and reference point electrode 105b3 just is put in volume preceding 302.These electrooculography signal electrodes are to select for use steel disc and device in mirror holder 112.
Fig. 4 is the key diagram of electrooculography signal.With the horizontal positioned method is example, does not do anyly when mobile with respect to reference point when eyeball, and electromotive force information is zero.Faint eye electromotive force information can move with respect to reference point along with eyeball what and change to some extent.What for example produced when eyeball moves right is positive potential information, and what produced when eyeball is moved to the left then is negative potential information.
The principle that realizes each physiological parameter measurement in the utility model is described below in conjunction with Fig. 5 a to 5d.
In the utility model, the measurement of physiological parameter utilizes the photoplethaysmography method to realize.Easy to use, the safety of photoplethaysmography method, and long-time the use also can not be caused user's discomfort.Utilize the device of photoplethaysmography method detection signal to generally include a sensor unit, it has a light-emitting device, as photistor, light is injected into the surface of measuring position, as finger, ear-lobe or forehead and a reception electro-optical device, as photoelectric detector, detect from the light of measuring position reflection or transmission.Because arteriopalmus causes the variation of volume of blood flow in the blood vessel, so the also corresponding change of the absorption of light, reflection and scattering.Therefore, receive also corresponding the changing of the detected light intensity of electro-optical device, this light intensity signal can be further processed and analyze after being converted into electric signal.
As previously mentioned, sensor array 115,116 and 117 detected signals are the photoplethaysmography signal, and it and heartthrob are synchronous.Therefore, shown in Fig. 5 a, the time interval (intervali) between the point can calculate heart rate value at the bottom of adjacent two summits of this signal or adjacent two by calculating.In order to reduce the error of calculation, we adopt average (Ave-interval) in ten time intervals to calculate instantaneous heart rate (HR), shown in formula (1) and (2).Also can calculate the changes in heart rate rate by this time interval, it is the standard variance in a certain number of time interval.
Because the material of two kinds of main extinctions in the blood, oxyhemoglobin and haemoglobin are different to the degree of absorption of light in red range and infrared light scope, therefore can determine arterial oxygen saturation by the light that utilizes two kinds of wavelength.As previously mentioned, place the photistor with different wave length, promptly two of ruddiness and infrared light photistors 116 and 117 can obtain two row photoplethaysmography signals simultaneously in same measuring position.At first this two column signal is carried out filtering and amplification.Direct current and AC portion with ruddiness and infrared signal separates then, and according to the principle of pulse blood oxygen instrument, we just can obtain arterial oxygen saturation by these two signals again.Its physical circuit is realized and can be found in " Designof Pulse Oximeters " by J G Webseter.Fig. 5 b has provided the synoptic diagram of the AC portion of the photoplethaysmography signal that the light by different wave length obtains.The calculating of arterial oxygen saturation is finished by following formula:
SpO
2＝110-25R (4)
AC wherein
RThe AC portion of the photoplethaysmography signal that representative is obtained by ruddiness, DC
RThe direct current component of the photoplethaysmography signal that representative is obtained by ruddiness; AC
IRThe AC portion of the photoplethaysmography signal that representative is obtained by infrared light, DC
IRThe direct current component of the photoplethaysmography signal that representative is obtained by infrared light.By asking for the ratio (3) between them, and utilize experimental formula (4), can try to achieve arterial oxygen saturation.
The calculating of blood pressure can be finished by dual mode:
Embodiment one
Place diverse location and two identical photistors of wavelength by making up two, we can obtain two row photoplethaysmography signals, exist certain time delay between these two signals, as from shown in Fig. 5 c.This time delay is called as the pulse wave transmission time.To normal adults, under its rest state, be 20～30 milliseconds from the time delay between the measured photoplethaysmography signal in ear upper and lower, and under the motion state, be 10～20 milliseconds.All introduced the method that the theory of utilizing the pulse wave transmission time is come calculating blood pressure in many documents and the patent.The pulse wave transmission time is meant that pulse arrives the mistiming between two differences when same artery transmits.This time delay is proved to be with blood pressure certain relation, and it can reduce with the rising of blood pressure.Therefore,, the relation between pulse wave transmission time and the blood pressure is calibrated, promptly find the relation between pulse wave transmission time and the blood pressure by utilizing the standard blood pressure instrument.Afterwards, just can utilize this time estimated blood pressure value.Its concrete computing method can be referring to United States Patent (USP) 4,869, and 262 and 5,649,543 etc., repeat no more here.
The common pulse wave transmission time is to determine jointly by the photoplethaysmography signal that electrocardiosignal and finger place obtain, and its sample frequency is elected 1000 hertz usually as.The scope in this pulse wave transmission time is probably at 100～200 milliseconds, greater than the pulse wave transmission time that obtains from ear.Therefore, when utilizing this method, the resolution that how to improve system under the prerequisite that does not increase system hardware and/or power consumption is very crucial.Hertz still can detect the photoplethaysmography signal though reduce sample frequency to 1000, but for obtaining from ear, has only 20～30 milliseconds pulse wave transmission time, but fail enough resolution is provided as sample frequency with 1000 hertz, so the sample frequency of optimizing in the present embodiment is chosen as 2000～3000 hertz to improve resolution.
Embodiment two
The another kind of method of calculating blood pressure is to utilize the waveform of upper arm blood pressure that the photoplethaysmography signal waveform that obtains from ear is proofreaied and correct.Thereby only utilize a train wave shape, promptly sensor obtains the information of blood pressure.At this moment need not to use sensor 115.The document of having delivered points out, exists certain relation between the waveform of radial artery blood pressure waveform and the photoplethaysmography signal that obtained by the finger place.Can be referring to document Modeling the relationship between peripheral bloodpressure and blood volume pulses using linear and neural networksystem identification techniques, John Allen and Alan Murray, Physiol.Meas., 20,1999,287-301 and Noninvasive assessment of thedigital volume pulse comparison with the peripheral pressure pulse, Sandrine C.Millasseau and Franck G.Guigui, et al., Hypertension, 36,2000,952-956.Similarly, the transport function of the relation between the photoplethaysmography signal at sign radial artery blood pressure waveform and ear place also can obtain.By utilizing one can carry out the device that continuous blood pressure measures from wrist and obtain the radial artery blood pressure waveform, and compare, can obtain this transport function, finish calibration steps with the photoplethaysmography signal waveform that the ear place obtains.It is pointed out that this calibration process is that object relies on.Therefore before using, calibrate respectively each user.Its concrete computing method can be referring to United States Patent (USP) 6,616,613.
Shown in Fig. 5 d, significantly also include the information of breathing in the photoelectricity plethysmogram signal.The respiratory rate of normal adults is per minute 10～20 times.The method of utilizing photoelectricity volume signal extraction respiratory rate is in recent years in the literature by extensive discussions, as document Respiratory rhythm detection withphotoplethysmographic methods, Dieter Barschdorff and Wei Zhang, Proceedings of IEEE-EMBS, pp912-913,1994 and Monitoring of heartand respiratory rates by photoplethysmography using a digitalfiltering technique, K.Nakajima, T.Tamura and H.Miike, Med.Eng.Phys.Vol.18, No.5, pp365-372,1996.Choose suitable wave filter and carry out low-pass filtering, can obtain respiratory waveform, thereby calculate respiratory rate.
