The specific embodiment
The application can fully be understood by following embodiment explanation, make those skilled in the art to finish according to this, yet the application's scope of patent protection be not limited to the following example.
Be different from the piezoelectricity sound of snoring sensing element that tradition is arranged at cervical region, piezoelectricity change type sound of snoring sensing element according to the present invention is arranged on the nose or nose zone on every side, just, the invention provides a kind of method of the detection sound of snoring of novelty, it is except having good measurement effect, user is also more convenient when measuring use, and manufacturing cost also can further reduce.
Near the sound of snoring pick off of operated by rotary motion nose mostly is mike, if will use a component of piezoelectric conversion time, then is arranged at cervical region more, and the employed component of piezoelectric conversion with disc type outward appearance that mostly is usually, SleepMate as shown in fig. 1
The piezoelectricity sound of snoring pick off of being produced (Piezo Sensor1250), but, because the surface of cervical region changes fluctuation ratio greatly, for example, as long as first rotation, fluctuations will take place in cervical region thereupon, therefore, tend to cause and have suitable diameter and hard disk is difficult to be attached to fully on the cervical region, in other words, still be easy to standing up even finish fixed disc type piezoelectricity conversion sensing element because of the sleeper by the attaching mode, actions such as rotary head and occur floating, situations such as perk, under this situation, the correctness of test can be under suspicion naturally.
Based on shortcoming in this respect, the inventor at how to improve studies.
Since the excessive situation of fluctuations takes place in cervical region easily, and the reason why component of piezoelectric conversion is arranged at cervical region is to be that the sounding position of the sound of snoring is a throat, then just think, if other measuring position is arranged can be obtained sound of snoring signal equally and also can have identical even better during measurement effect, be the good selection of replacement cervical region naturally.
Therefore, the present inventor promptly seeks as the basis with this.At first, the inventor finds, when taking place, the sound of snoring can not only have only throat in vibrative position, all can resonate but spread all over whole respiratory tract, therefore, utilize piezoelectricity change type element as sensing element since be, the respiratory tract of then whole in theory generation vibration can be the position of measuring, and in view of the above, the inventor has selected nose, reached nose zone on every side, because compare with cervical region, it is little that it understands the surface undulation variation that takes place, and the inventor believes, under the help of nasal cavity resonance, the intensity of sound of snoring signal should obtain raising to a certain degree.
As foundation, the inventor promptly experimentizes at this conception with this.At the beginning, the applicant adopts known employed disc type sound of snoring pick off when being arranged at cervical region earlier, finds after just the zone around it being arranged at nose or nose is measured, and effect also can't be compared when being arranged at cervical region.
Therefore, after by analysis, the applicant thinks, should be the diameter of traditional sound of snoring sensing element and thickness excessive and cause be provided with difficult, add docile property deficiency, the vibration that can't respond to nose fully and produced, thus the size of decision change component of piezoelectric conversion, in the hope of obtaining better result.And through after the test again, the inventor finds, reduces the size of component of piezoelectric conversion, for the quite positive help that obtains of sound of snoring signal.
Because nose is a vibration cavity, can reach the good result that enlarges sound of snoring vibration, adding the component of piezoelectric conversion that reduces volume, area can respond to the vibration of nasal cavity fully (whole element itself all can be sensed vibration because of less size integral body, but not has only induction area partly), therefore, under mutual cooperation, measured sound of snoring signal is not only clear, and, even measured signal when being arranged at cervical region greater than known sound of snoring pick off.
And in order to reduce the size of sound of snoring sensing element, the present invention all develops to differ from known sound of snoring pick off part in structure and making.
For can clearer understanding, the applicant carries out rough narration to the structure of known disc type sound of snoring pick off earlier.
At first, well-known, the employed material of component of piezoelectric conversion mostly is combining of a conductive material and a piezoelectricity material, promptly, it is to utilize piezoelectricity material induction user skin because of the vibration that the sound of snoring produced, and then with transfer of vibration to conductive material, and then form the signal of telecommunication.
In known sound of snoring pick off, shown in Fig. 2 A, Fig. 2 B, it is to utilize a conductive material 10 as bottom mostly, cover a piezoelectricity material 12 more thereon partly, for example, ceramic material, afterwards, between cross-over connection one electrical components 14, for example, a resistance, and external connection, thus, just can be when sensing vibration, the loop is measured in formation one, and all weld/electroplate at these layer/elements/after configuring, last as shown in Figure 1 plastics or the rubber that utilizes again coats it, promptly finishes known disc type sound of snoring pick off.Therefore, obviously, known piezoelectricity sound of snoring pick off has suitable thickness, and, also having and do not include little diameter (especially for being positioned over situation on the face), also it is not easy to be attached at fully the reason of cervical region just for this.
As for sound of snoring sensing element of the present invention, then similar with the prior art shown in Fig. 2 A and Fig. 2 B, it also is the structural principle that adopts conductive material carrying piezoelectricity material, so advantage is, does not need special material, does not also need special process technology, so therefore cost can not increase, just, for the improvement that all greatly reduces on width, thickness in response to sound of snoring sensing element of the present invention, it is all different with known technology on structure and production process.
At first, in configuration aspects, of the present invention is a multiple structure, as Fig. 3 A, shown in Fig. 3 B and Fig. 3 C, this multiple structure comprises a conductive material layer 20, one piezoelectricity material layers 22 and two electric connection layers 24, wherein, this piezoelectricity material layers 22 is by 20 carrying of this conductive material layer, for example, can utilize the mode of coating and piezoelectricity material 22 is arranged on the conductive material 20, to form a coalition with a conducting surface and a piezoelectricity sensitive surface, afterwards, the electric connection layer 24 of the external connecting line of one connection then can be set respectively on this conducting surface and this piezoelectricity sensitive surface, for example, a typical plane joint, as shown in Figure 3A, certainly, the joint of other kind form is feasible equally.
At this will be, this joint can not weld with paying special attention to, only need simply be positioned on conducting surface and the piezoelectricity sensitive surface to get final product, so the plane joint can be preferable selection.As for emphasizing that the reason that can not weld then is, the sound of snoring sensing element that width according to the present invention has significantly dwindled, its easy to make unlike known configurations on weld job, therefore, if when being embodied as with known the same making step, in operation, may increase complexity on the contrary, and, on production process, can reduce the reduction that any step is all being represented cost.
And the present invention is in response to this set-up mode that does not weld the time, then be that piezoelectricity material with this sound of snoring sensing element covers this conductive material fully, and do not adopt known part coverage mode, avoiding under the situation of not welding, the two-sided meeting of conductive material causes short circuit because of contacting same jointing simultaneously.
In addition, if adopt welding step in processing technology, during with the increase fixed effect, then the requirement of the covering relation between this piezoelectricity material and this conductive material is not strict, and need not must be as take complete coverage mode above-mentionedly.
Then, after this multiple structure setting is finished, just can simply its whole parcel/encapsulation be got up, for example, utilize heat-shrinkable T bush or silica gel etc., and the strength by shrink wrapped, even under the situation that is not having welding, jointing is fluid-tight engagement between realization and conducting surface and the piezoelectricity face easily.
Be with should be noted that, compare that the present invention is not arranged at employed resistance in the known technology in the sound of snoring sensing element with known step.
This be because, among technical conceive of the present invention, be in order to simplify known processing technology to reduce cost, also be to cause for fear of reduced volume to improve the processing technology operation complexity, so the processing technology thereof in the sound of snoring sensing element is reduced to minimum as far as possible, so, as previously mentioned, the present invention wishes to reduce as far as possible as welding waits trickleer and may need manually-operated step, to help the automatization of processing technology, also reduce cost, for example, when covering fully in the piezoelectricity material under the situation of conductive material, after finishing under large tracts of land in advance, cuts again making step even can be reduced to, thus, if when adding the step of welding resistance, though then non-infeasible, but still can cause delaying of processing technology.
Therefore, resistance is not to be arranged among the sensing element, get final product but only need be positioned at arbitrary place of measuring on the loop (by sensing element and external device (ED) 26 formed measurement loops), so, in the present invention, this resistance is arranged on the external connecting line of this sound of snoring sensing element or is arranged among the device 26 that is connected with sound of snoring sensing element, as shown in Figure 4, thus, the step of welding resistance can be omitted equally.
So far,, not only obtain on the fabrication schedule to simplify, on manpower and material resources cost, also all obtain to save, the more important thing is that the volume of sound of snoring sensing element has obtained reduction really by the step of omitting welding resistance and connecting connecting line.
In addition, if when seeking contacting between sensing element and (nose) skin than driving fit, before encapsulation, also can insert convex object 28 in advance, shown in Fig. 5 A, Fig. 5 B, to help the realization convex, to meet the outward appearance that nose rises and falls, then be to be arranged at single face (Fig. 5 A) or two-sided (Fig. 5 B) as for this convex object, the present invention is unrestricted.
According to above-mentioned steps, structure and after the sound of snoring sensing element that completes, test through this case inventor confirms, be arranged at nose or nose this Improvement type multilamellar sound of snoring piezoelectricity sensing element on every side, its detected sound of snoring signal is not only quite clear, also quite sharp, promptly, according to the measurement effect of sound of snoring piezoelectricity sensing element of the present invention not because this is in order to the structure-improved of realizing reduced size and simplify fabrication schedule and decay to some extent, on the contrary, it becomes integral body on the contrary because of reducing of size all can carry out induced sensing element, has quite good measurement effect.
It is but, most important that still its restriction on being provided with is quite little.
Because this motion that can take place when sleep of nose is fewer, the influence of also more not stood up, leaning to one side to oppress, therefore, be arranged at the mode of cervical region, simply go up many according to mode of the present invention compared with tradition, it is quite obvious to add the vibration that nasal cavity produces, this makes that more the intensity of detection signal is quite enough, thus user be no longer necessary for fixing and spent sizable time, for example, stick many adhesive tapes, also can not feel uneasy because of a large amount of adhesive tapes of cervical region.
In addition, sound of snoring sensing element according to the present invention is when reality is implemented, the consideration reason of decision volume size mainly contains two, first, compared to cervical region, nose, and the zone around the nose is obviously less, second, be arranged at sensing element on the face, under the identical situation of effect, be the smaller the better naturally, to reduce foreign body sensation, therefore, the sound of snoring sensing element of made to have broken away from traditional cervical region component of piezoelectric conversion because of the excessive shortcoming that breaks away from easily of contact area, also allows attaching comparatively convenient promptly in the effort that reduces aspect diameter and the thickness according to the present invention, and, the further advantage that reduced volume more can bring manufacturing cost to reduce.
Say again, because when carrying out the sleep-respiratory state-detection, need the sensing element that is provided with quite a lot of, even among the simplest test, also can use two kinds pick off usually, with as the most basic mutual correction.And rule of thumb, under the situation that adopts sound of snoring pick off, what Chang Gongtong used is exactly respiration pickup, no matter is breast abdominal respiration sensing or respiratory air flow sensing, so, in this case, if as known technology sound of snoring pick off is arranged at cervical region the time, then user is bound to such an extent that bearing at least two connecting lines on one's body, promptly, article one, be connected on the face or the breast abdomen, another is connected to cervical region, and is obviously inconvenient to some extent.
Because the respiratory air flow pick off is arranged on the face the respiration channel, therefore, if can be in conjunction with conception of the present invention, all be under the situation about being arranged on the face then in the sound of snoring and two kinds of pick offs of respiratory air flow, the idea that both are combined is easy to naturally and can realizes, thus, the quantity of connecting line also can be reduced naturally, improves user degree of convenience in the use.
Moreover, take a broad view of whole sleep detection, especially needs are detected electrocardio, brain, myoelectricity, eye movement, breathe, the sound of snoring, the complete PSG (polysomnography) of various physiological signals such as blood oxygen detects, among numerous required pick offs, place the pick off of cervical region that one of the sound of snoring is only arranged, so, when if sound of snoring pick off is arranged on the face according to the present invention, the pick off that then is arranged on the face just can combine, for example, utilize identical connecting line together, to realize reducing the purpose of connecting line complexity, the relative wish that also promotes user acceptance test.
In addition, than tool advantage ground be, since employed little according to the general tradition of volume ratio of sound of snoring sensing element of the present invention, therefore, provide if necessary detect redundant with as timing, sound of snoring sensing points more than one can also be set, for example, may be embodied as two sensing elements, for example, be arranged on the both sides of nose or nose peripheral region or the same side all can, so, when reality is implemented, more selectivity can be arranged.
As for selecting being provided with aspect the position of sensing element, test according to the present application people, except nose itself, zone around the nose, for example, in nasal bone (between two), two cheekbones and the formed quadrilateral area of oral area, as shown in Figure 6, also can be used as the position of measuring sound of snoring vibration, promptly, the setting of sound of snoring sensing points is not limited on the nose, use habit that can the person of being used and elasticity to some extent also can cooperate other pick off, for example, the respiratory air flow pick off is provided with the position and adjust.
So far, according to above-mentioned, the present invention is in order to produce the piezoelectricity conversion sensing element of sound of snoring signal, it not only can obtain clearly sensing signal, volume is also small and exquisite many, therefore, is well suited for really being arranged at user on the face, and, can also further reduce manufacturing cost by the simplification on structure and the production process.
And after finishing sound of snoring piezoelectricity conversion sensing element, as Fig. 7 A, shown in Fig. 7 B, in the time of if it will being arranged on the zone around nose or the nose, the help that then small and exquisite sound of snoring piezoelectricity conversion sensing element 30 needs by an attachment features 32, wherein, this attachment features 32 can be that a tool is fit to carry out the adhesive plaster that nose is provided with external form on every side, film, promptly, one attachment features (Fig. 7 A and Fig. 7 B) through design, perhaps, this attachment features also can merely be exactly general adhesive tape, for example, and breathable adhesive tape, in other words, the function of this attachment features is exactly to be this sensing element is attached at zone around nose or the nose, as shown in Figure 8, as for other as external form, aspects such as material are then unrestricted.
In addition, this attachment features is when being attached at nose or nose peripheral region with this sensing element, the quantity of the sensing element that it can be provided with also can be according to need and is different, for example, can homonymy or not homonymy etc. be provided with two, certainly, also be to fix with the respiratory air flow pick off.
As for employed this piezoelectricity material, then aforesaid is common piezoelectricity material, and for example, monocrystalline class (single crystal) is as quartz, tourmaline, LiNbO
3, LiTaO
3In crystal, thin film class (thin film), as ZnO etc., polymer class (polymer), as PolyVinylidene Fluoride (PVDF) etc., ceramic-like (ceramic) is as BaTiO
3, cobalt lead titanates (PZT) etc., and composite (composite material), as PVDF-PZT etc., this conductive material then can be chosen as metal.Under the situation that adopts known material, just can not increase cost because of manufacturing difficulty.
In sum, the invention provides a kind of piezoelectricity conversion sensing element of measurement sound of snoring electricity physiological signal of novelty, and utilize it to produce the method for sound of snoring electricity physiological signal, wherein, though what adopted is employed piezoelectricity material of known sound of snoring pick off and conductive material, but be different from utilization under the situation of the structure of known technology and processing technology, the present invention has realized that volume is little many, the novel piezoelectric conversion element that easier attaching and signal sensing ability are better, in addition, except the structure of improvement sound of snoring piezoelectricity sensing element, the present invention also moves to user nose or nose zone on every side with the position of sound of snoring sensing from cervical region, not only solved the shortcoming of floating easily when being arranged at cervical region, the probability that can combine with other pick off on the face also is provided, alleviated the too complicated problem of connecting line when carrying out the sleep disordered breathing detection, and, under the situation that adopts the less piezoelectricity conversion sensing element of volume, except allow the enforcement that is arranged at nose or nose peripheral region more convenient, relatively also reduced the burden of cost, therefore, novel sound of snoring sensing element according to the present invention was different from really in the past and is more more progressive than known technology.
