Specific embodiment

Referring to Fig. 2, it is the circuit diagram according to the present patent application finger-worn type physiology detection apparatus.

Firstly, physiology detection apparatus according to the present invention will include an at least optical sensor, it is electrically connected to a control list Member, and operated by the control of the control unit, and then obtain blood physiology information.

And it is as shown in Figure 2, all components are all connected to control unit in physiology detection apparatus, wherein the control list Member includes an at least microcontroller/microprocessor, and is preloaded with program, to control the communication between hardware component, the control list Member may achieve different hardware component and be connected between external application/external device (ED) of the present patent application physiology detection apparatus Signal transmission, also, it also allows the behavior of device that can be programmed, to respond different operational circumstances and the micro-control Device/microprocessor processed also can be using timer internal (not shown) come generation time stamp or the time difference or for controlling operation.

In the present patent application, optical sensor refers to while having light emitting source, for example, LED and photodetector, for example, Photodiode (photodiode), sensor be and as is well known to utilize PPG (photoplethysmography, light volume change graphy figure) principle, is emitted beam by light emitting source into tissue, And photodetector can receive and penetrate blood or the light reflected through blood in blood vessel, and then by obtaining light because of blood The volume occurred changes and can get blood physiology signal, therefore the commonly referred to as blood physiology signal as acquired by optical sensor For PPG signal, wherein PPG signal, which will include, to be fast moved component (AC Component, AC component), and reaction is passed by artery Pulse wave caused by the myocardial contraction sent, and move slowly at component (DC Component, DC component), response organization's blood The relatively slow variation of volume, for example, breathing chest and abdomen rise and fall, influence caused by sympathetic and parasympathetic activity；In addition, passing through Analyzing PPG signal also can get the physiologic informations such as relevant blood vessel hardness and blood pressure；Furthermore it is learnt through Physiological Experiment, PPG arteries and veins Wave can obtain the situation of each internal organs and heart rate generation harmonic resonance after frequency-domain analysis, thus can be total to this pulse wave heart rate harmonic wave Vibration distribution is applied to the diagnosis of Chinese medicine and the monitoring of blood circulation of human body, for example, the first of liver and Liver Channel and palmic rate Harmonic wave is related, and kidney and kidney channel are related to the second harmonic of palmic rate, and the third harmonic of spleen and the spleen channel palmic rate is related, lung And the 4th harmonic wave correlation and stomach and the 5th harmonic wave of stomach meridian palmic rate of lung channel palmic rate are related.

In general, according to the difference of the type and quantity of the included light emitting source of optical sensor and photodetector, it can The blood physiology information of acquirement is also different, and for example, which may include an at least light emitting source, for example, LED Or multiple LED, it is preferred that green light/infrared light/feux rouges, and an at least photodetector, with obtain pulse rates/heart rate with And the blood physiologies information such as breathing chest and abdomen fluctuating；Wherein, when measuring pulse rates/heart rate, green light and wavelength are in green light Visible light below, for example, blue light, white light, are the main using light source of current measurement heart rate, and mainly focus on AC component Partial interpretation, in addition, being then in relation to the influence that breathing chest and abdomen rise and fall for blood, when a personal breathing, in chest cavity Pressure (so-called intrathoracic pressure) can with each respiratory change, wherein when air-breathing, thoracic cavity can be expanded and intrathoracic pressure is caused to subtract It is few, thus air is pumped into lung, during expiration, intrathoracic pressure increases and forces air that lung is discharged, these intrathoracic pressures change Become also result in via vein return to heart blood volume and heart squeeze into artery blood volume change, and this part Changing can be learnt by analyzing the DC component of PPG signal.

Alternatively, the optical sensor may also comprise at least two light emitting sources, for example, multiple LED, it is preferred that green light/infrared Light/feux rouges, and an at least photodetector, to obtain blood oxygen concentration (SPO2), pulse rates/heart rate, and breathing chest and abdomen are risen The blood physiologies information such as volt, wherein when measurement blood oxygen concentration, need the light emission of two different wave lengths to enter in tissue, utilize blood In oxygen-containing ferroheme (HbO2) and non-oxygen-containing ferroheme (Hb) have different degree of absorption to the light of two kinds of wavelength, and connecing Receive and penetrated, after the light that reflects, the two comparison result can determine blood oxygen concentration, therefore, the measurement of blood oxygen concentration generally for There is more limitation in the setting position of optical sensor, is preferred with the position that light can be squeezed into really in artery, for example, finger, hand Slap inner face, toe, sole etc., and two kinds of different wave lengths then can be, for example, feux rouges and infrared light or two kinds of wavelength Therefore green light, can select suitable light source on demand, not limit if wavelength is respectively the green light of 560nm and 577nm System.

The wave-length coverage of above-mentioned various light sources is that about between 620nm between 750nm, infrared waves are about red light wavelength Greater than 750nm and green wavelength about between 495nm between 580 nm, and when being used to measure, generallys use, illustrate For, red light wavelength 660nm, infrared light wavelength 895nm, 880nm, 905nm or 940nm and green wavelength 510~560 Nm or 577nm, however, it is noted that in actual use, according to the difference for using purpose, other wavelength can also be used Light source, for example, when only heart rate to be obtained, wavelength is less than other visible light sources of green light, also that is, wavelength less than 580nm can It is light-exposed, for example, blue light, is also one of selection, moreover, other than using the single light source of specific wavelength, it is possible to use include The composite light source of the wavelength, for example, white light；Furthermore when obtaining heart rate, in order to eliminate noise, for example, ambient noise, wearing Noise caused by period body action etc., may also set up multiple light sources, (and wavelength is unlimited, can be all green light, it can also be used The light source of his wavelength), and by being handled by digital signal by between PPG signal acquired by different light sources, as adaptability is filtered Wave device (Adaptive Filter) is subtracted from one another etc. and to calculate and achieve the purpose that eliminate noise, therefore there is no limit.

And the control unit then at least will also include AFE(analog front end) (AFE) circuit to reach physiological signal acquirement, with It executes, for example, various for other known to Analog-digital Converter, amplification, filtering and those skilled in the art The hardware and/or software of signal processing since this is well known content, therefore do not repeat.

In addition, the finger-worn type physiology detection apparatus applied according to the present invention may also include a wireless transport module, for example, Bluetooth, BLE, Zigbee, WiFi, RF or other communications protocol and/or a USB interface, it is wireless to be carried out with an external device (ED) It links up, wherein the external device (ED) may include, but be not limited to, wisdom mobile phone, tablet computer, laptop, individual calculus Machine or intelligent object wearing device, for example, smartwatch, Intelligent bracelet, wisdom glasses etc., and wireless ditch general rule makes information It can be exchanged between device, but also the operations such as information feedback, long-range control and monitoring can carry out.

Furthermore the finger-worn type physiology detection apparatus applied according to the present invention also may include an electric power mould group, for example, button Type battery (button cell), alkaline battery or rechargeable lithium battery, alternatively, alternatively, there is charging module, for example, sense Inductive charging circuit, alternatively, passing through, selectively, the port USB or spring thimble (pogo pin) charge；In addition, tool selection Ground, the finger-worn type physiology detection apparatus applied according to the present invention may also comprise an information provider unit, it is preferred that a LCD Or LED display component, with display, for example, statistical information, analysis is as a result, the event stored, operation mode, process, battery shape State, or more information；And the finger-worn type physiology detection apparatus applied according to the present invention may also include data storage element, compared with It is a memory goodly, for example, a random access memory (RAM) or an internal flash or a removable memory disk, with storage Physiological signal/the information accessed.

In addition, it is noted that in general, finger-worn type physiology detection apparatus mainly can be divided into two types, first is that, Be divided into different housings between the control unit and optical sensor, and connecting line formed electrical connection by way of, it is another then It is that the control unit and optical sensor fall in the intracorporal form of the same shell, and in the next narration of the present patent application, The contents such as related structure change and operation behavior are then all suitable for this two types, there is no limit.

Then, the finger-worn type physiology detection apparatus applied according to the present invention will also include a finger and wear structure, for passing light Sensor is set on finger, so that an at least optical sensor can be steadily set on finger skin surface, and then is ensured The acquirement of blood physiology information.

Just it has been observed that the present patent application is other than wanting to improve comfort level when wearing, it would also be desirable to provide can basis Use demand it is different and actively in response to physiology detection apparatus, to achieve the purpose that round-the-clock to use, therefore, according to this hair The overall structure of bright application physiology detection apparatus and internal component configuration suffer from design unlike the prior art.

Firstly, ring is preferably divided into two parts by the present patent application: one is not bending with regard in terms of overall structure Part and a deflectable portion, wherein not bending part is used to carry optical sensor, and deflectable portion is then used to will not Deflectable portion is fixed on finger.And it is then described below using configured in this way reason:

It is well known that the shape that the ring round that closed round or open c-type is general ring can mostly use, although The cross section of the finger of human body is not circular, but when ring is by as decorative use, only need to ensure that ring is not fallen off i.e. Can, the identical and not required that they be so of shape between the two, still, when optical sensor is further formed as ring form, the two Between misfitting for shape can but bring great adverse effect.

For example, usually rigid ring when select size, most need consider be can by the joint of finger, and perhaps More people are to prevent ring from falling off by the circumferential differences between joint and non-articular portion, therefore, work as ring when wearing ring Refer to by behind joint, the situation often having is very much, ring round is with more loose situation around finger joint, and this is carry out physiology The situation being least happy to see when measurement, because, it is however generally that, the gap between optical sensor and skin is smaller, acquired signal It is better, and be especially preferably, if slight pressure can be applied to optical sensor according to studies have shown that, make its between skin more For fitting, more preferably effect will be can reach；In addition, difference of the finger of human body with physiological status, it at any time may variation difference Size, for example, body processes state, become fat, Fingers may all be influenced by reducing etc. encloses size, it is known, for example, that i.e. Make on the same day, refer to enclose there may also be significant change, therefore, the not bending property of general rigid ring will be unable to adapt to dynamic The finger of state variation encloses, and is also unable to adjust the pressure with skin contact, is not easy to obtain moderately good signal.And this is also existing Even if finger ring type physiology detection apparatus provides, large-scale product size is available, is also difficult to ensure setting for optical sensor The reason of setting the quality of stability and acquired signal.

Accordingly, the present patent application using deflectable portion and it is adjustable guard against enclose the problem of being designed to deal with this respect.

Fig. 3 A-3B is please referred to, is the signal for wearing physiology detection apparatus according to the adjustable finger of one embodiment of the present patent application Figure, with free both ends, one first free end 101 and one second free end 102, also that is, when it is not arranged at hand When on finger, present it is open band-like, when being measured on finger to be set to, then can by first free end and this Two free ends be combined with each other, and form a ring body, to be sheathed on finger；Also therefore, this, which refers to, wears at least one of structure Point, it especially needs to be formed by bending first free end and second free end of ring body, can be made by deflection material At for example, silica gel, rubber, flexible plastics, cloth etc., there is no limit can also pass through other than it can cooperate digital flexion The elasticity and/or retractility of material itself generate force to finger, help to fix, it helps the setting of optical sensor.

In this case, deflectable portion, which surround the radian formed, will be different from not bending part, thus can It is not only restricted to the rigid ring of tradition and is generally round fixed shape, therefore be remarkably contributing to promote ring entirety and finger watch Compactness between face, is added, and the non-articular portion of finger more allows flexible portion originally i.e. there are the deformable possibility of stress The elasticity divided can show maximum adaptability.

Then, in order to can be combined with each other first free end with second free end, to form ring body, this first from By being provided with the adjustment mechanism being mutually paired, the first adjustment mechanism and second adjustment mechanism on end and second free end, As shown in Fig. 3 A-3B and Fig. 4, having on first free end has multiple positioning on positioning piece and second free end Structure, therefore, when locating piece be combined with each other with location structure, this refers to that a ring body can be formed by wearing structure.

The advantage being designed in this way is, when the locating piece is in conjunction with the location structure of different location, is formed by ring body Size is difference, and has different circular perimeters, in this way, generate the effect of adjustable ring body size, and is suitable for not With finger size, for example, the different fingers of same user or the finger of different users or different time is same One finger, thus it is not necessarily limited to the size bought, quite there is advantage.

Therefore, by the use of the ring body of adjustable size and deflection material, that applies according to the present invention is adjustable Finger wears structure while wearing completion, the not only configuration of achievable optical sensor, moreover it is possible to generate naturally to the finger of wearing Towards the force in the finger cross section center of circle, so make optical sensor reach stablize fitting finger skin state, be quite have it is excellent The mode of gesture.

The embodiment of locating piece and location structure has various possibility.In one embodiment, as shown in figs 3 a and 3b, should It is adjustable to refer to that the band body for wearing structure is embodied as having multiple holes, wherein an at least column is provided on the first free end 101 Body 103 is used as locating piece, and the hole on the second free end 102 is then used as positioning hole 104, and, tool selectively, should The front end that an at least cylinder passes through positioning hole can further have a positioning limiting section 1031, have less times greater than location hole Therefore the width of hole dia, passes through second free end by an at least cylinder to help the fixation of an at least cylinder On positioning hole, which wears structure and can form ring body, to be sheathed on finger, and by making an at least column Body passes through different positioning holes, may achieve the ring body of different circumferential sizes, upper quite convenient operating with, wherein should An at least cylinder is implementable to be multiple, preferably fixes and positions effect to have, and there is no limit for example, can be circle for shape Column, the various shapes such as corner post, square column and this at least a positioning hole hole similarly can be various shape, therefore, there is no limit.

In addition, also implementable hole 105 is distributed on first free end, in this way, this at least a cylinder can be real It applies and provides user as shown, cylinder is embodied as being fastened on the form in hole for removable form and voluntarily adjust position A possibility that setting promotes aesthetic feeling in addition, two band bodies is also allowed to have symmetrical appearance, meanwhile, multiple holes also contribute to being promoted saturating Manner and increase comfort.

Also, can also be further embodied as, hole 105 is additionally set outside positioning hole, further reaches promotion to obtain The effect of air permeability, especially hand are the positions of frequent activity, other than stickiness and sampling effect, when also needing to consider long Between wear the various problems that are likely encountered, and reduce the mode with the contact area between body and skin in this way, really can be effective It reduces and wears the issuable feeling of oppression and heat of institute, along with embodiment so is suitable for various materials, for example, silica gel, rubber Glue, fabric etc., therefore be the selection of suitable tool advantage；In addition, also can provide the effect for referring to and wearing structure fine tuning, this is because hole Setting can make with long axis of body to restraint become smaller, thus except the effect of deflection, then additional generate can small range elasticity Flexible effect, and such effect then facilitates finger is allowed to wear structure and is more bonded finger, is also equal to allow not bending part The optical sensor carried can more stably skin-proximal, can especially realize and stressed best effective slightly is applied to optical sensor Fruit also allows the size of formed ring body that can more adapt to finger size institute in daily life and issuable changes a little.

Wherein, in particular, the finger size size based on size and different users between different fingers has centainly Difference, as generally ring is subdivided into multiple sizes on the market, along with make can for the lesser cross section perimeter of finger The range being adjusted is also small, therefore in the preferred embodiment of the present patent application, the diameter and adjacent holes of each hole Distance between hole has its optimum range, for example, it is preferred that the diameter of hole between 0.5-1.5 millimeters, and adjacent holes Distance between hole, then between 2-3 millimeters, applicant has found distance after testing preferably between the center of circle and the center of circle, so Distance configuration, can it is without offset adapt to various sizes finger.

In another embodiment, as shown in figure 4, locating piece and location structure, which are embodied as the adjustable finger, wears structure With the velcro hair side 201 and velcro hook surface 202 on body, here, hair side in addition to being set as segmentation as shown in figure Outside form, also can continuously it be arranged, for example, one section of hair side of setting, or directly the band is formed using the fabric of tool hair side effect Which kind of form no matter body use, all can reach the effect for being suitable for various sizes finger, therefore, there is no limit, moreover, In one embodiment, it is preferred that this can be further embodied as being made using the fabric of tool retractility with body, for example, fine containing Lycra The cloth of dimension, so that it may provide small-scale telescopic effect by cloth itself, similarly help to finger is allowed to wear structure and be more bonded Finger helps to make the gap between optical sensor and skin to minimize, and then reaches the best setting state slightly to press, And further, in one embodiment, can also open up a hole in cloth, and by shell is sticked in it is therein in the way of into Row is fixed, and further achievees the effect that simplified processing procedure.

Here, it is noted that the above-mentioned embodiment in relation to deflectable portion is for example purposes only, rather than conduct Limitation, any adjustable reshaping refers at the size of ring body and the deflection of tool telescopic resilience wears structure, and all category the present patent application are intended to The range of opinion, it is unrestricted.

On the other hand, the present patent application is in addition to reaching any variation ring body size using deflectable portion and providing steady Fixed to fix fitting strength and telescopic elastic to reach outside the effect slightly to press for optical sensor, also cooperation uses Not bending part, such as the shell 100 as shown in Fig. 3 A-3B and Fig. 4, one provides protective effect, for example, can prevent The fails in compression such as optical sensor, circuit, two provide between light emitting source and photodetector fixed relative position, then can then lead to Hard characteristic is crossed further such that can be evenly distributed by centripetal force caused by deflectable portion, allows optical sensor Contact more average temperature between finger, and then avoid being set to that flexible portion timesharing is issuable to be connect such as the prior art The unstable situation of contacting surface.

Firstly, wearing the design of structure in response to the finger of flexible portion point is so had, the present patent application is set to not bending Light emitting source and photodetector in part are embodied as being disposed adjacent to each other, and as seen in figures 12 a-12 c, such as distance is less than 8mm, And be preferably set on same plane, in this way, no matter be formed by how ring body size changes, light emitting source and light are examined Survey device between relative position will not all become, can improve it is aforementioned in the prior art may because finger size change due to generate displacement Potential uncertain factor, also allow many on sampling stability height.

Here, it is noted that the sampling mode that above-mentioned light emitting source and photodetector are disposed adjacent, as aforementioned institute The reflection sampling mode of meaning, however, just it has been observed that the quantity of light emitting source and/or photodetector used by the present patent application can To be multiple, therefore, according to the difference of arrangement mode, transmitting and the receiving angle of light be will be different, and have various possible realities Apply mode, as long as therefore light emitting source and photodetector arranged adjacent be arranged, and need to be arranged between each light emitting source and photodetector Directly output signal is caused to be easily saturated phenomenon on light leakage to photodetector for preventing the light of light emitting source without human body Light barrier (light barrier) person, be all the scope that the present patent application is advocated, be not only restricted to reality listed herein Apply a content.

And then there are many may for the combination between deflectable portion and not bending part.In one embodiment, this refers to It wears structure and is embodied as that there is an accommodating space 300, as shown in figure 5, to accommodate a shell 100, and this is then provided in the shell Optical sensor, the control unit and other circuit units, in this way, by hardness possessed by the shell, the accommodating Space and the shell form not bending part, wherein the implementable shell is with inner space to accommodate circuit The form of component, also be embodied as being used in circuit external filling such as resin can thus change material and form the form of hard shell, and Optionally, the shell is implementable for removable form；Alternatively, further, it can also be as shown in Figure 9 A, the accommodating space It is embodied as being mutually clamped with the hull outside structure of the not bending part, to achieve the effect that limit and fixation, therefore, not have It is restricted.

In addition, first free end and second free end also are embodied as being incorporated into shell opposite sides, such one Come, which has independently formed the not bending part, and in this case, same there are many may.

For example, in one embodiment, the section of deflectable portion as figs. 6 a-6 h illustrate and not bending part The schematic diagram of figure and deflectable portion combines between the two using combining hole 401 and reaching in conjunction with cylinder 402, is scheming In 6A-6D, this combines cylinder to be implemented as on a shell 100 of the not bending part, and relatively, the combined hole Hole is then embodied as being located on the deflectable portion 400, therefore, passes through the deflectable portion by the combination cylinder on the shell On this combine hole, which can be fixed on the shell；In addition, this combines cylinder in Fig. 6 E-6H Then to be carried by the engaging member 403 in addition used, in this case, then be on the shell and the deflectable portion all Can correspondingly have in conjunction with hole, for this combine cylinder also cross and reach fixed effect, for example, utilizing material, knot Structure and achieve the effect that mutual close-fitting and interfere, and the engaging member is in addition to as shown in Fig. 6 E-6H with from the left-hand of figure Right passing through combines outside hole, also is embodied as passing through to the left from the right of figure, there is no limit.

And in particular, this combine cylinder and this combine hole set-up mode be, this combine cylinder long axis direction It is about in parallel and hole in conjunction with this hole on the deflectable portion with finger position normal to a surface direction is worn Be formed by face then with to wear finger position normal to a surface direction about perpendicular, and in this way, either phase In conjunction with or it is detached from one another be all convenient to reach, be the selection of a tool advantage.

It combines the front end of hole that can further have one to combine limiting section 4021 in addition, this combines cylinder to pass through, has big In the width for combining hole diameter, to help this to combine the limit and fixation of cylinder, for example, can shape at L-shaped (Fig. 6 C) or T shape (Fig. 6 A) or other shapes (Fig. 6 E, 6G)；And the material of the engaging member has biggish range of choice, for example, can be used hard Material, such as metal, plastics, can also be used by hardness be modulated to compared with softwood matter, such as rubber, silica gel；In addition, the combined hole Hole and this to combine cylinder then implementable be various shape, for example, round, rectangular, polygon, asymmetrically shape etc., therefore, There is no limit.

Alternatively, other forms can also be used and reach combination between the two, for example, Fig. 7 A shows the feelings using sliding slot Shape and Fig. 7 B show the situation using holding section, for example, using setting shaft, such as metal rotating shaft, and the shell with two sides Body engaging；In addition, combination between the two can also be completed by the design of structure while manufacture, for example, shell point can be made It for upper and lower two parts, and will be directly located in body between two parts up and down, the mode that embedment is projected can also be used to reach band Combination between body and shell.

Moreover, above-mentioned various integrated structures may be implemented in the two sides of shell, unilateral side also may be implemented in, it can also two sides point Therefore integrated structure etc. that Shi Yong be not different can have various possibility, and derivative knot is generated even from previous embodiment Structure variation, it is unrestricted as long as the combination and fixation that may achieve between the two also fall within the range to be advocated of the present patent application.

Further, it is preferred that the not bending part is implementable for a concave surface, with close to finger Ergonomic structure, also that is, at finger setting position cross section periphery, for example, this concave surface and finger cross section is outer Week is least partially overlapped, and the part being overlapped includes at least the setting position for having optical sensor, can not in this way, be set to Optical sensor in flexed portion, so that it may by this concave surface more successfully close to finger surface, so that physiology The acquirement of information is more stable.

Here, it is that the concave surface is unlimited for which kind of form, for example, it may be arc, polygonal, irregular shape etc. is all It is feasible, also, it is preferred that further there is change in shape, example at the position of concave surface setting optical sensor 500 It such as, can be in locally be embodied as plane (Fig. 8 A) or protrusion (Fig. 8 B) etc., to reinforce optical sensor and the stickiness of skin and contact Stability also promotes the quality of sample signal simultaneously.Therefore, it is preferred that emphasis is, indent, which is formed by space, can accommodate finger, and The optical sensor being set on concave surface may achieve the steady contact with finger, therefore be not only restricted to above-mentioned cited shape.

When the not bending part is embodied as with concave surface, other than using general common plane battery, example Such as, rectangular battery outside button cell, in one embodiment, it is preferred that arc battery can also be used, is more in line with finger arc Degree, it will help reduce the thickness of the not bending part.

And when the not bending part is embodied as with concave surface, it is preferred that the concave surface is formed by arc Degree can adapt to different finger sizes, for example, the different fingers of same user or the finger of different users, citing and Speech can choose in the size distribution of general ring, fall in intermediate partially large-scale size, for example, U.S.'s ring finger size No. 10-12, and be changed based on this radian, then light sensor is cooperated to be to be arranged at single position, For example, the middle of the concave surface, in this way, which intermediate size bigger than normal is in addition to that can ensure thicker finger size energy Outside being enough inserted in, it equally can also allow between the not bending part with optical sensor and thinner size finger reach well contacting, have Help expand the range of applicable finger size.

In addition, the long axis direction length of the not bending part of tool concave surface, also that is, its radian covering finger is crosscutting The range of face periphery, equally also quite important, for example, coverage area is excessive to may cause adaptable finger size model It encloses and becomes smaller, coverage area is too small, sense of stability and polarization may be made to reduce, it is thus preferable to be, for example, selection covering The range of the about 180 degree of finger cross section periphery, or about 120 degree of ranges, or about 90 degree of range, or between 60-210 degree it Between suitable range, there is no limit.

Therefore, as long as the suitable finger ergonomics such as shape, volume of the not bending part shell, even with It, also can be by referring to that the deflection ring body size adjusting for wearing structure and elasticity fine tuning compactness are arranged such as the stiff shell of plastics In finger surface, this also quite has advantage for the manufacturing.

And it is equally applicable that, the not bending part is also implementable not have concave surface, as shown in Fig. 5 and Fig. 9 A, Under this situation, as long as the bottom of the not bending part can be limited in the range of general finger width, by adjustable Advantage is used brought by the deflectable portion of whole size, is equally suitable for different finger sizes, and is set to thereunder Optical sensor then can equally have good and stable contact between finger, and signal needed for obtaining, and will not be to wearing Finger generates excessive burden, is all feasible mode therefore, and is next to have the not bending part of concave surface Main embodiment narration, is equally applicable to the not bending part for not having concave surface, there is no limit.

Furthermore in order to enable light, successfully self-emitting light source enters finger and reflected light detector, is set to light sensing Material between device and finger should be selected as light-permeable material, also that is, the transparent material of optical source wavelength that light emitting source is issued, For example, the eyeglass (lens) of light-permeable, the encapsulating material of light-permeable, a part of shell of light-permeable etc., there is no limit.

On the other hand, it since the physiology detection apparatus of the present patent application uses the class ring form around finger, therefore wears Position can generally fall in the finger joint where proximal phalanx or middle phalanx, as shown in Figure 9 A, however, unrestrictedly, by this hair It is bright to apply for that the deflectable portion used carry out size adjusting, and can provide the force towards finger cross section center of circle direction And elastic telescopic a little, even if being set to finger joint where distal phalanx can also easily reach good as shown in Figure 9 B Fixed effect, and the stability in order to further ensure that setting, where being arranged at distal phalanx when finger joint, this, which refers to, wears knot Structure can be further provided with an anticreep drop piece 601, as shown in Figure 9 C, to provide the usage experience more felt at ease；In addition, when setting When being placed in finger tip, similarly, it is preferred that other than the adjustable finger illustrated such as Fig. 3 A-3B can be used and wear structure, The fabric of tool retractility can be used as deflectable portion, and as locating piece and determined using the hook surface and hair side of velcro Bit architecture achievees the effect that stable fitting with the flexible nature by fabric, therefore, is not provided with position limitation, can be according to reality Border use demand and select.

Furthermore this refers to that wear structure also implementable for replaceable form, for example, be embodied as multiple fingers wear structure all can be with Same shell combines, to be changed to different tape body lengths, and/or be changed to different adjustment mechanisms etc., more broadly to fit Answer the size difference of various fingers and finger position, for example, the thickness difference of male and female finger, same user compared with The size of finger joint where finger joint where size difference and proximal phalanx between thick finger and thinner finger and distal phalanx Difference etc., for example, form as figs. 6 a-6 h illustrate, user manual operation can execute easily deflectable portion with Combination and releasing between not bending part, thus replacement of the different length with body can be carried out, and in particular, when using such as When this conveniently replaced structure, even if the not bending part is embodied as not having two free ends, such as Fig. 6 C-6D and 6G- Shown in 6H, and it is to provide multiple kinds of length selections, and is pacified by the length that user's selection is most suitable for itself finger size Dress is equally the form of suitable tool advantage.Therefore, there are various possibility, do not limited by illustrated embodiment.

According to the finger sectional view of the distribution map (please referring to Figure 10) of blood vessel in finger and Figure 11 A-11C it is found that finger Interior arterial vascular distributing position is the direction for falling in finger two sides and being biased to the centre of the palm, it is, falling in finger cross section lower half Portion.

In this case, if blood oxygen concentration to be obtained and other physiologic informations, as previously mentioned, two kinds of wavelength can be used Light source, for example, the green light or infrared light and feux rouges of two kinds of wavelength, are preferably set to finger cross for optical sensor The lower half of section, it is ensured that incident light and reflected light path pass through artery, obtain enough signal quality, another party to determine If single wavelength light source, such as green light can be used need to only obtain pulse rates/heart rate in face, infrared light, feux rouges etc., and can It is set in the upper half or lower half in finger cross section, it is, the acquirement of blood oxygen concentration has stringenter limitation, in addition to It needs outside two kinds of wavelength light sources, it is also necessary to which optical sensor is disposed proximate to the finger cross section lower half of artery, another party Face, the acquirement of pulse rates/heart rate at least only needs single wavelength light source to may achieve, and the limitation of sample position is smaller, so And multiple or multi-wavelength light source can be also added, to obtain more preferably signal quality, therefore without limitation.

And two kinds of very huge detection demands of such difference, it is generally difficult to utilize same detection device in the prior art Adjustable finger to reach, but apply through the invention wears physiology detection apparatus, and such target becomes feasible.

This is because it is by not bending part and adjustable that the adjustable finger of the present patent application, which wears physiology detection apparatus, Deflectable portion the two of domain body size is combined to be formed, and therefore, tool is advantageously that the not bending part can basis The change of measurement demand and convert different setting positions, also that is, dynamically changing measurement position, also therefore, light source select It selects, in the case of the mutual cooperation of allocation position and mode of operation, aforementioned two kinds of measurements will all can be performed, and be no longer limited by list Kind measurement method, thus can realize the round-the-clock finger-worn type physiology detection apparatus used.

In actual use, for example, it as shown in Figure 11 A-11C, only needs simply according to physiologic information to be obtained Type and the position for moving the not bending part, so that it may different physiologic informations is obtained, in this way, either detect blood The demand of oxygen concentration or the demand for detecting other blood physiology information, can all be satisfied, for example, dense when needing to obtain blood oxygen When spending, moves the not bending part and optical sensor is made to fall in the position where arteries 701, also that is, finger 700 The lower half in cross section, for example, be rotated by 90 ° to side (Figure 11 A), or the bigger angle of rotation is to finger pulp (Figure 11 B), with The optical sensor is set accurately to obtain signal from the position of blood vessel, in addition, when being intended to obtain other blood physiology information, For example, then the limitation of sample position becomes smaller when heart rate, for example, the upper half (Figure 11 C) in finger cross section can also obtain, phase When convenient；Furthermore alternatively possible situation is, according to using opportunity, signal type to be obtained and signal quality difference and The position of the mobile not bending part, for example, for same index finger, finger joint where distal phalanx is common blood Oxygen concentration obtains position, and even if optical sensor to be set to the upper half of distal phalanx place finger joint, may also obtain blood Oxygen concentration (Fig. 9 B, 9C), and finger joint where proximal phalanx or middle phalanx is then suitble to be worn (figure during daily routines 9A)。

So binding site can be mutually adjusted simultaneously by elasticity provided by the deflectable portion and its two free end Reach the characteristic that dynamic adjusts ring body size, no matter the not bending part is arranged at which position of finger, can all obtain Good fixation also makes the optical sensor reach stabilization with being bonded between skin, and ensures signal quality.

Also therefore, adjustable finger provided by the present patent application, which is worn physiology detection apparatus and realized, round-the-clock is suitable for making With and all can obtain the target of high quality physiological signal and approximate physiological information, for example, during activity on daytime, in order to Hand motion might as well be hindered, optical sensor can be set to the upper half in finger cross section, obtain heart rate etc., to allow user Physiological change during solution activity is also conveniently watched via various information provided by information provider unit, furthermore, so Moulding is similar with general ring, beautiful and do not show lofty, is quite suitble to routine use, on the other hand, during sleep, due to Hand activities demand is less, therefore even if optical sensor is set to finger cross section lower half or is set to distal phalanx institute It is also without prejudice in finger joint, at this point, other than heart rate, with regard to can also further obtain blood oxygen concentration, with understand more with sleep phase The information of pass, for example, whether there are the information such as Sleep Apnea symptom and sleep quality during sleep.

Moreover, even if there is the monitoring requirements of blood oxygen concentration during activity on daytime, since formed ring body size can be certainly By adjusting, therefore can be measured by replacement allocation position, for example, habit is worn in the third finger when measuring heart rate usually, and It is also replaceable to such as food other than it can rotate directly down to finger lower half and measure when having blood oxygen concentration measurement demand On finger or thumb, the not bending part is placed using the larger space for less influencing hand grasping between this two finger, For example, index finger is towards the side of thumb, in this way, even if measurement for a long time be also it is feasible, break through the limit on the opportunity of using System, and blood vessel thicker in index finger or thumb is also because there is biggish blood flow, it is possible to provide signal noise ratio (S/N Ratio) Preferable signal, in addition, also can be moved to finger joint where distal phalanx if only needing the measurement of progress short time, it is equally feasible Mode quite there is advantage moreover, need to can only be readily accomplished by adjusting the binding site with body.

Therefore, it for user will be that operation is simple, conveniently, and carry-on physiological detection equipment vdiverse in function.

It is following then describe and how to configure light emitting source and photodetector, function is used to achieve the effect that maximize.

Since the main target of the present patent application is all to obtain desired blood physiology information under any circumstance, Therefore, light emitting source how is selected and configures, and photodetector how is arranged just to become critically important.

In one embodiment, the finger-worn type physiology detection apparatus of the present patent application is embodied as having simultaneously that there are three types of wavelength Light source, for example, the first light emitting source generates the light of first wave length, such as infrared light supply, the second light emitting source generates the light of second wave length, If red light source and third light emitting source generate the light of third wavelength, such as green light source, for example, Figure 12 A-12C show three The arrangement of kind wavelength light source and photodetector may, wherein in fig. 12, single infrared light supply 81 and single red light source 82 are used to obtain blood oxygen concentration with one of photodetector 91, and green light source 83 is then embodied as two, and with another light Detector 92 is used to obtain heart rate；In Figure 12 B, each infrared light supply 81, red light source 82 and green light source 83 and single light Detector 90 is used to obtain blood oxygen concentration and heart rate；In fig. 12 c, single photodetector 90 in addition to single red light source 82 and single infrared light supply 81 obtain outside blood oxygen concentration, also obtain hearts rate with three green light sources 83.

In other embodiments, three kinds of wavelength light sources are also implementable selects for other, for example, first wave length, the second wave Long and third wavelength light is all embodied as green light, or, the light of first wave length and second wave length be embodied as green light and The light of third wavelength is embodied as infrared light or feux rouges etc., therefore, there is no limit；Furthermore above-mentioned light emitting source and photodetector row Column mode is also for example purposes only, can have different arrangement modes according to actual needs, also without limitation.

Found by above-mentioned, the luminescence component of green light be implemented as it is multiple, for example, two or three luminescence components, and such as Advantage brought by this set-up mode is, since the measurement of heart rate is mostly during daily routines, have biggish probability occur because Hand activities, shaking and influence being bonded between optical sensor and skin, therefore, the setting of such multiple luminescence components can reach The effect being further compensate for, when the light that wherein some luminescence component is issued, which can not be successfully, is reflected into photodetector, The luminescence component of still another position is available, or when multiple luminescence components can all obtain signal, can also increase reflection Path helps to obtain signal noise than good and high quality signal, therefore either in terms of signal acquirement or physiologic information, There is positive help.

In another embodiment, then it is embodied as the light emitting source with two kinds of wavelength, for example, feux rouges and infrared light, as preceding It states, other than it can obtain blood oxygen concentration, feux rouges or infrared light also can be used for obtaining heart rate, or be embodied as the green of two kinds of wavelength Light, similarly suitable the present patent application can the not bending part of dynamic mobile position novel embodiment.

In addition, in the selection of photodetector, when detecting blood oxygen concentration, due to containing other light sources in environment, It is preferred that lesser size may be selected in the photodetector for receiving infrared light, it is saturated to avoid because of environment light；On the other hand, To receive the photodetector of green light, then biggish size may be selected, increase effective reflected light, and further takes and can obstruct Other light sources, such as low frequency infrared light, processing procedure, to obtain the signal for having preferable S/N ratio.

Therefore, in the selection of optical source wavelength and quantity, there can be various change, as long as can reach raw needed for acquirement The effect for managing information, is all enforceable form, there is no limit.

Here, it is noted that according to can be seen that in the finger sectional view of Figure 10 Vessels of hand distribution map and Figure 11, hand The center of finger is phalanges 702, therefore when the upper half for being arranged at finger cross section obtains heart rate, for example, using green light or red When outer smooth, the position of centre is preferably avoided, and be set to the finger upper half there is relatively abundant physiological tissue and higher blood The left and right sides of flow, to obtain signal noise than preferable signal；In addition, it is preferred that by the arrangement of multiple light emitting sources For the direction parallel or perpendicular to blood vessel, also that is, the long axis direction of finger, so that passing through the road of blood vessel between different light sources Diameter difference reduces, and helps to obtain and improves signal quality.

Further, the finger-worn type physiology detection apparatus applied according to the present invention, in addition to obtaining blood using optical sensor Physiologic information, also provided with other physiological sensing components, to obtain other physiologic informations.

In one embodiment, control unit can be electrically connected to by setting electrode and obtain electro physiology signal, wherein electricity Pole may be disposed on the surface of ring interior side contacts finger, may also set up in ring outer surface, for example, when in inside And outside is when being all arranged electrode, by making the electrode in outside contact other positions of body, for example, body, another upper limb, under Limb, head etc., by the measurement of executable electro-cardio signal；When two electrodes are arranged in inside, then skin can be obtained from finger Electric signal, the especially needed above-mentioned spinning movement of this situation, because the measurement of skin electric signal is with by handing in autonomic nerve The sweat gland state that determines of activity of sense nerve and the Skin Resistance changed, and be then distributed with sweat gland abundant on the inside of hand, It is exactly the lower half in cross section for finger, it therefore, can be freely by electrode rotary to finger by spinning movement The lower half in cross section is more conducive to the acquisition of skin electric signal.

Therefore, the finger-worn type physiology detection apparatus of the present patent application is also implementable for according to the setting of not bending part The difference of position and obtain different types of physiological signal, for example, on the not bending part simultaneously be provided with light biography In the case of sensor and electrode, so that it may obtain blood physiology signal and electro physiology signal respectively and shifting one's position, example Such as, heart rate can be obtained in the finger upper half and lower half, and obtains skin electric signal in finger lower half, alternatively, Blood oxygen concentration can be obtained in finger lower half, and obtain electro-cardio signal etc. in the finger upper half and lower half；In addition, It can also be used to obtain the electro-cardio signal of different heart projection angles, for example, when the not bending part is set to the finger upper half When, electro-cardio signal acquisition is carried out using the exposed electrode on the outside of the other hand touching ring, is formed by the heart to obtain two upper limbs Dirty projection angle electro-cardio signal, also that is, lead I in limb lead, and when being set to finger lower half, then in operation compared with It is easily that touching body trunk by the hand of wearing apparatus makes exposed electrode contact body skin, so can then obtains Limb and trunk are formed by heart projecting angle electro-cardio signal, for example, LA-V5 lead or LA-V6 lead, therefore be all implementable And combination quite helpful for daily physiology monitoring.

In another embodiment, it may also set up temperature sensor, to obtain the body temperature information and/or environment temperature of user Information, when being especially embodied as ring form, user has very big probability that can use in daily life, thus can be used for supervising Daily Temperature changing is surveyed, helps user to know more about the physiological change of itself, or provide variation of ambient temperature.

Here, it is noted that include in the obtainable physiologic information in the finger upper half, but be not limited to, heart rate/arteries and veins It fights rate, ecg information, myoelectric information etc., in finger lower half, obtainable physiological signal then includes, but does not limit, blood oxygen Concentration, heart rate/pulse rates, skin power information, ecg information, myoelectric information, temperature etc., therefore, combinations of the above are only to lift Example explanation, rather than limit, it can be selected according to actual use demand.

It in another embodiment, then is that can add accelerometer, for example, three axis (MEMS) accelerometer, with definition device Posture in three-dimensional space, and it is then the body gesture that can be directly related to user, wherein the accelerometer can return The measured acceleration value in all x, the tri- dimension directions y, z, and according to these numerical value, it can derive and obtain various In relation to posture, the information of movement, for example, in daily life, can be used to the daily routines (actigraph) for recording user, For example, moving distance, step counting, calorie consumption etc.；And during sleep, then it can be mentioned by understanding the activity situation of hand For the information in relation to body action, for example, turning over, if it has fallen asleep, the information such as sleep state, not only for understanding user's Physical condition is helpful, can also be when interpreting other physiological signals as auxiliary, for example, being used to move using adaptive filter Except, because of noise caused by body action, and then having more accurate judgement in PPG signal.

According to the conception of another aspect, the finger-worn type physiology detection apparatus of the present patent application is also quite appropriate for sleep period Between use.

As previously mentioned, the PPG signal according to acquired by optical sensor, can obtain as pulse rates/heart rate, blood oxygen are dense Degree, chest and abdomen breathing such as rise and fall at the blood physiologies information, and these blood informations then similarly help to interpret the life during many sleeps Phenomenon is managed, for example, a kind of quite valued symptom is sleep disordered breathing, and optical sensor institute in sleep study field The blood physiology information that can be provided then facilitates to understand sleep disordered breathing.

One of sleep disordered breathing is sleep apnea (Sleep Apnea), and general there are three types of types: resistance Plunger type sleep apnea (Obstructive Sleep Apnea, OSA), maincenter type sleep apnea (Central Sleep Apnea, CSA) and mixed type sleep apnea (Mixed Sleep Apnea, MSA), hereafter referred to collectively as exhale Suction event (Breathing Event).

Obstructive sleep apnea (OSA) is mainly characterized by during sleep, wholly or partly due to the upper respiratory tract Block and formed the phenomenon of the reduction of a period of time internal respiration air-flow or suspension, moreover, usually under the saturation degree of blood oxygen concentration It drops (desaturation), OSA is a kind of common sleep disordered breathing, and there are about 25~40% in middle aged population to be affected.

Maincenter type sleep apnea (CSA) is caused by going wrong because of the mechanism that is breathed of brain driving muscle, So that there is the stopping of short time in the nerve driving of breathing muscle, and these not equal transition possibility from 10 seconds to 2 to 3 minutes It can continue the time in entire evening, maincenter type sleep apnea is similar to obstructive sleep apnea, can be in sleep period Between cause gradually to suffocate, as a result cause individual from sleep by of short duration wake-up (arousal), and second wind simultaneously Function, and also with obstructive sleep apnea similarly, maincenter type sleep apnea can lead to cardiac arrhythmia, high blood The diseases such as pressure, heart disease and heart failure.

Mixed type sleep apnea (MSA) refers to obstructive sleep apnea and maincenter type sleep apnea The situation that the two mixedly appears.

Apnea anoxic index (Apnea Hypoxia Index, AHI) is the one of sleep apnea severity A index combines the quantity of apnea (apnea) and low pass gas (hypopnea), can assess sleep simultaneously to provide One whole sleep apnea severity scale of (breathing) interruption times and oxygen saturation degree (blood oxygen level), In, AHI is to calculate acquisition and the total hourage divided by sleep by apnea and low pass gas event, usual AHI value Be divided into, be for 5-15 times per hour it is slight, it is severe that 15-30 times is moderate per hour per hour > 30.

Other than AHI, research is confirmed, another important indicator of assessment or detection sleep apnea is oxygen saturation It spends index of unsaturation (Oxygen Desaturation Index, ODI), refers to during sleep oxygen level in blood per hour Decline a degree of number from baseline, it is however generally that, the representation of ODI has, the number of oxygen saturation decline 3% (ODI3%) and oxygen saturation decline 4% two kinds of number (ODI4%), for ODI unlike AHI, AHI is further comprised can It can cause sleep awakening (awaken) or awakening (arousal), but not influence the event of oxygen level, and be confirmed through research, There is certain correlation between ODI and AHI and sleep apnea, can be effectively used for diagnosis OSA, and since ODI is from blood oxygen Concentration calculation and obtain, therefore ODI also belongs to one kind of the raw information of blood.

The patient of most of OSA can generate more OSA events when facing upward the sleeping position lain, this is because facing upward on when lying Respiratory tract is easier to be affected by gravity and generate and collapse, and in the literature, is formally diagnosed as Postural OSA (Positional OSA, POSA) foundation be that AHI value is greater than a certain critical value with the non-difference faced upward when lying in facing upward to lie, for example, POSA wherein one The common definition of kind is to be greater than twice of the non-AHI value faced upward when lying or more in facing upward AHI value when lying；It is learnt by research, POSA's Popularity rate increases with the severity of OSA and is successively decreased, and 70%~80% POSA patient tool is slightly serious to the OSA of moderate Degree, wherein slight OSA patient's highest in Asia has 87% patient that can be classified as POSA.

Another common sleep disordered breathing is snoring, influences 20%~40% in total population, such generation noise Symptom when being due to sleep upper respiratory tract air-flow by when soft tissue that vibration occur to generate, OSA and serious beat Snore be studied confirm it is highly relevant with many clinical symptoms, such as daytime drowsiness, melancholia, the formation of hypertension, ischemic Heart disease, cranial vascular disease etc., and wherein, it is most normal with the symptom occurred in OSA for snoring, and it is also universal to snore It is considered the premonitory phenomenon of OSA generation, the origin cause of formation based on the two is all related with the narrow physiological phenomenon of the upper respiratory tract, appearance of sleeping Also the same severity for affecting snoring symptom of gesture.

According to studies have shown that along with the evolution of upper respiratory tract stenosis, it is often the case that first generate and sleep The relevant snoring symptom of posture, when more serious then even if it is non-face upward lie when start to be easy to happen snoring, and start to develop into slight OSA, and the generation snored and the correlation of sleeping posture are gradually reduced, further, OSA severity also by with sleep appearance Gesture is relevant slightly to moderate, eventually becomes the severe situation less relevant with sleeping posture.

Sleeping posture training (Sleep positional Training, SPT) is that one kind can treat POSA and Postural The postural training device of a new generation has been developed in the method for snoring in recent years, by the central axes of body, for example, neck, chest Attitude sensor is arranged in portion or abdomen, for example, acceleration transducer, and when the sleeping position for detecting user is to face upward to lie, warp By generating faint vibration warning, and promotes user to change sleeping position and lies to avoid facing upward, pointed out via many research reports, By this simple effective therapeutic modality, i.e., avoidable patient faces upward in sleep to lie, and then OSA event is greatly reduced Quantity occurs.

Only, such training method still has improvable space, for example, since the patient of OSA or snoring have difference tight The differences of Physiological of weight degree and individual, therefore before being trained, if evaluation function can be provided, specific aim just can be provided Training program and expected information in relation to training effect；In addition, during SPT, if can also provide sleep and breathing letter Breath, can will also adjust whereby the parameter setting of device, to achieve the purpose that improve training effect.

And the finger-worn type physiology detection apparatus of the present patent application, as previously mentioned, acquired PPG signal is in addition to that can obtain Blood oxygen concentration to calculate outside ODI value, in addition, can also cause the heartbeat of relativity too slow due to obstructive sleep apnea and The increase of PPG pulse wave amplitude, increases sharply there are also the heart rate occurred after the respiratory obstruction and strong blood vessel is received Contracting, and root is pointed out it was found that having report, for having sleep disordered breathing patient, is occurred compared to heart rate (HR/PPI) Variation, respiration case and awakening are more to variation caused by PWA and/or PA.

Wherein, as shown in figure 13, PPI is spaced (Peak-to-peak interval) between referring to peak value: it is defined as PPG Time difference in signal between two continuous peak values.Firstly, the peak value (Peak.amp) in each period of detection PPG signal, and The time label of all Peak.amp points is stored in array buffer, PPI is calculated as between continuous P eak.amp point Time difference, in order to obtain accurately as a result, the zone of reasonableness of PPI value can be set, for example, PPI<0.5 seconds (>120 beat/min) Or PPI>1.5 second (<40 beats/min) are considered as exception and are removed.

PWA refers to pulse wave amplitude (Pulse wave amplitude): it is defined as peak amplitude (Peak.amp) and wave Difference between paddy amplitude (Valley.amp), Peak.amp and Valley.amp are the minimum and maximum vibrations in each PPG period Width point.Firstly, all Peak.Amp and Valley.amp points are all detected as the local maxima and smallest point of PPG signal, if When appearance the case where lacking Peak.amp point, Valley.amp point immediately is also rejected, finally, by from immediately preceding Valley.amp is subtracted in Peak.amp to calculate PWA.Since Peak.amp and Valley.amp point only detects in pairs, otherwise Give up, therefore, PWA value will not be caused to malfunction due to one of value loses, in addition, if there are any exceptions Peak.amp point then excludes them by the filter mentioned in PPI feature extraction.
