Health form to determine that device 1 also comprises measuring unit, and this measuring unit is used to measure a plurality of width W of the abdominal part of human body 20, as shown in Figure 2.This measuring unit comprises a pair of contactless distance measuring sensor,, is bearing in supporting leg 3a and the first sensor 6a on the 3b and the second pick off 6b of supporting member 14 respectively that is.First sensor 6a and the second pick off 6b are arranged in the relative both sides of supporting member 14 inherent human bodies 20.Each pick off all is an optical distance sensor, and it has: luminous organ is used for flatly launching light beam (such as but not limited to, infrared beam); And optical receiver, be used for receiving from the light of pick off the place ahead something (for example, human body 20) reflection and be used to produce and the corresponding signal of distance from respective sensor to this pick off the place ahead something.Like this, the spacing between each sensor measurement respective sensor and this pick off the place ahead something.
In Fig. 1 and Fig. 2, arrow LA and LB represent from pick off 6a and the horizontal emitted light beams of 6b.Under state shown in Figure 2, first sensor 6a measures the first space D A between first object's position on itself and the human body 20 and that the first horizontal survey line (from the path of the light beam of pick off 6a) is crossing, and the second pick off 6b measures the second space D B between second object's position on itself and the human body 20 and that the second horizontal survey line (from the path of the light beam of pick off 6b) is crossing.As depicted in figs. 1 and 2, first slotted line is identical with second slotted line.
During first sensor 6a vertically moves, first sensor 6a measures apart from a plurality of first space D A1 to DA4 of a plurality of first (left side) object's position on many on the same vertical plane first parallel, horizontal slotted lines, and each first spacing is positioned between the sensing station of first sensor 6a and first (left side) object's position on the human body 20.When the second pick off 6b vertically moves, the second pick off 6b measures apart from a plurality of second space D B1 to DB4 of a plurality of second (right side) object's position on many second parallel, horizontal slotted lines (it is on the vertical plane identical with the residing vertical plane of first slotted line), and each second spacing is positioned between the sensing station of the second pick off 6b and second (right side) object's position on the human body 20.Therefore, although measuring unit only has two pick offs, each single-sensor can be in a plurality of spacings of measuring a plurality of object's positions on the human body 20 on a plurality of parallel, horizontal lines.In Fig. 3, show the first space D A1 to DA4 and the second space D B1 to DB4 as example; Yet, should be appreciated that the quantity of spacing is not limited to the quantity in the shown embodiment.
Although moved pick off 6a and 6b, because support legs 3a is parallel with 3b, so the interval of the horizontal range on the horizontal direction that is parallel to first slotted line and second slotted line INT remains unchanged between pick off 6a and the 6b.Like this, can estimate a plurality of object width candidate W based on a plurality of first space D A and the second space D B and constant interval INT, it is the candidate item of abdominal part width value Wsbj (that is the maximum among the object width candidate W).For example, when space D A1 and DB1 were positioned at sustained height, object width candidate equaled INT and deducts DA1 and deduct DB1 again.Similarly be that another object width candidate equals INT and deducts DA2 and deduct DB2 again.The 3rd object width candidate equals INT and deducts DA3 and deduct DB3 again, deducts DA4 and deducts DB4 again and the 4th object width candidate equals INT.As being appreciated that according to Fig. 3 each object width candidate W is the distance between one of one of first (left side) object's position and second (right side) object's position.
True abdominal part width value is approximately equal to the maximum among above-mentioned a plurality of object width candidate W.When the vertical dimension that reduces the horizontal survey line at interval and when increasing the quantity of the spacing of measuring, can improve the estimated accuracy of abdominal part width value Wsbj.
With reference to the block diagram of Fig. 4, form the electric structure of determining device 1 with describing health.Circuit in the above-mentioned connecting portion 2 comprise microcomputer 8, this microcomputer 8 be connected with lower member: display 4, manual interface 5, pick off 6a and 6b, driving mechanism 7a and 7b, electrode 15 and umbilicus position indicator 18.Microcomputer 8 is driven by power supply 13, and the processor that comprises memorizer 12 and comprise controller 9, computer 10 and determiner 11.The function of controller 9, computer 10 and determiner 11 is realized by software.

In addition, memorizer 12 stores people's abdominal part width value and the above-mentioned correlation between the waistline.Computer 10 is not only as distance calculator, but also as the waistline computer, i.e. waistline accountant, be used for calculating human body 20 based on this correlation that is stored in memorizer 12 with the corresponding waistline of determined abdominal part width Ws bj.
This correlation is to estimate according to the data that record of a plurality of human bodies in advance with adding up.For example represent this correlation, but be not limited thereto with the regression formula of determining based on the measurement result (it is shown in Figure 5) of many people's abdominal part width value that records with CT and waistline.Be expression collinear exemplary regression formula shown in Figure 5 below.
Y＝aX+b
Wherein, " Y " is people's waistline, and " X " is people's abdominal part width, and " a " and " b " is constant.Constant " a " and " b " preferably are respectively 3.01 and-10.2, but they are not limited thereto.Preferably, constant " a " is greater than 2.3 and less than 3.14, and constant " b " is selected according to constant " a ".For example, constant " a " can be 2.49, and constant " b " can be 10.5.
In addition, memorizer 12 stores the body compositions indicator formula that calculates the various body compositions indicators of human body based on bio-electrical impedance and waistline.Computer 10 is also calculated device as body composing meter, be that body composing meter is calculated device, be used for calculating human body 20 based on the body compositions indicator formula with bio-electrical impedance that records with electrode 15 and the corresponding body compositions indicator of waistline that calculates by the waistline computer.The body compositions indicator formula for example can be the formula that is used to calculate as the interior fat index of body compositions indicator well known in the art.
With reference to flow chart shown in Figure 6, form using and operating of definite device 1 with describing health in more detail.Memorizer 12 is for good and all stored and is used to control the computer program that health is formed definite device 1.Microcomputer 8 carries out work according to this computer program.The step of being carried out by microcomputer 8 in the operation of this flow chart is corresponding to the element of this computer program or this computer program.In the present embodiment, memorizer 12 usefulness are acted on the storage medium of storage computation machine program or program element, but another memorizer or storage device can be used as this storage medium.Can adopt semiconductor memory, hard disk, CD, digital versatile disc, floppy disk or other suitable storage mediums for this reason.
After the on and off switch of handling manual interface 5 was switched on, at step S1, the operator formed definite device 1 according to the mode that makes frame 14 be positioned at human body 20 tops with health and is placed on the bed 30.Below operation is the step that microcomputer 8 is carried out according to program.
At step S2, microcomputer 8 determines whether that the measurement of pressing manual interface 5 begins switch.If press, then handle and proceed to step S3, carry out initialization in 8 pairs of whole systems of step S3 microcomputer.For example, the position of 8 couples of pick off 6a of microcomputer and 6b and the data in the memorizer 12 are carried out initialization.
After system initialization, at step S4, with control driving mechanism 7a and 7b synchronously movable sensor 6a and 6b, and being used for start sensor 6a and 6b, to measure (sampling) the first space D A and the second space D B one right as controller 9 for microcomputer 8.
Be appreciated that when processing turns back to step S4 from this flow chart, pick off 6a and 6b just be moved in synchronization and by starting measuring the next right of first spacing and second spacing, thereby scan human body 20 with certain sampling time interval.Each driving mechanism 7a and 7b under the control of controller 9 with identical speed movable sensor 6a and 6b so that this move and measure during pick off 6a and 6b remain on sustained height.Sampling period be multiply by the translational speed of pick off 6a and 6b at interval, obtains sampled distance (the distance interval of horizontal survey line) at interval.For example, when sampled distance be that speed will be 0.02 meter per second when 1 micron and sampling period being 50 milliseconds at interval at interval.
At step S5, microcomputer 8 is as computer 10, be used for based on above-mentioned horizontal range at interval the first space D A that recorded last time of INT and pick off 6a and 6b and the second space D B to calculating up-to-date object width candidate W.

If this up-to-date object width candidate W is bigger, then handle and proceed to step S7, at step S7, determiner 11 is wiped the largest object width that before is stored in the memorizer 12, and in memorizer 12 this up-to-date object width candidate W is stored as new largest object width.That is the largest object width in the determiner 11 updated stored devices 12.Then, processing proceeds to step S8.Otherwise, if this up-to-date object width candidate W is not bigger, then handles and be directly to step S8, and the largest object width in the updated stored device 12 not.
At step S8, microcomputer 8 is used for determining as determiner 11 whether the first sensor 6a and the second pick off 6b arrive it and move boundary 6L (see figure 3).For example, based on the gait of march of pick off 6a and 6b and from the starting position to the length of mobile boundary 6L, come calculating sensor 6a and 6b to arrive the required duration of mobile boundary 6L.With this long in case of necessity being stored in the memorizer 12, and microcomputer 8 has intervalometer, and this intervalometer is used for autobiography sensor 6a and the 6b elapsed time that begins to have advanced is counted.When elapsed time reaches described long time in case of necessity, determiner 11 determines that pick offs have arrived boundary 6L.
If pick off no show boundary still 6L then handles and turns back to step S4,, measure next first spacing and next second spacing at step S4.If pick off arrives boundary 6L, then handle and proceed to step S9.The largest object width that is stored at last in the memorizer 12 is defined as abdominal part width value Wsbj.At step S9, microcomputer 8 is carried out the subroutine of the waistline and the body compositions indicator that are used to calculate human body 20.Then, at step S10, microcomputer 8 serves as display controller, is used to make display 4 to be presented at the value and the body compositions indicator of the waistline that step S9 calculates.Microcomputer 8 control display 4 are so that display keeps a period of time with shown waistline and body compositions indicator.Because display has at least temporarily kept shown value, thus finish measure after the operator can easily confirm shown value, even and finish measure after pick off unexpectedly mobile, also can avoid changing shown image.After step S10, processing finishes.
With reference to flow chart shown in Figure 7, form the definite operation of device 1 in step S9 shown in Figure 6 with describing health in more detail.At step S11, microcomputer 8 reads the regression formula of the correlation between expression abdominal part width value and the waistline from memorizer 12.
At step S12, microcomputer 8 is as computer 10 (waistline computer), is used for calculating based on this regression formula and determined abdominal part width the waistline Y of human body 20.
At step S13, microcomputer 8 is measured bio-electrical impedance by mode well known in the art based on the signal that provides from electrode 15.Then, at step S14, microcomputer 8 reads the body compositions indicator formula that is used to calculate body compositions indicator.At step S15, microcomputer 8 is as computer 10, is used for calculating human body 20 and bio-electrical impedance that record and the corresponding body compositions indicator of waistline that the calculates index of interior fat (for example, about) based on this body compositions indicator formula.Can calculate body compositions indicator by disclosed mode in TOHKEMY 2006-288735 communique (2006 open).By reference its disclosed full content is incorporated into this.Body compositions indicator for example include but not limited to subcutaneous fat area, subcutaneous fat thickness, abdominal part total fatty area, interior fat area, torso portion fat than the fat of, whole health than and abdominal muscles thickness.After having calculated body compositions indicator, handle the step S10 that proceeds in the main routine shown in Figure 6.

As shown in Figs. 8 to 11, what waistline accountant 101 comprised is portable supporting member 114, rather than the supporting member in first embodiment 14.As shown in Figure 10 and Figure 11, supporting member 114 flatly is placed on the front surface of human body 20.Supporting member 114 is provided with horizontal adjustment auxiliary unit 119 (for example, level indicator or angular transducer), be used for assist operator with supporting member 114 be adjusted to level (that is, with the floor or the bed 30 surperficial parallel).
Supporting member 114 has contact site 120.Contact site 120 is the recesses that can be contained in the curved shape on the front surface of abdominal part of human body 20.Contact site 120 can stably be positioned on this front surface supporting member 114 (waistline accountant 101).In addition, rely on contact site 120, reduced the change of supporting member 114 with the relative position of human body 20.Can make this front surface distortion though place supporting member 114, with inventor's experience, this abdominal part distortion is less than the caused influence to waistline of breathing to the influence of waistline.Therefore, even supporting member 114 directly is placed on the abdominal part, also can highly reproducibly accurately measure waistline.
In addition, supporting member 114 has the umbilicus position indicator 118 of the residing reference position of umbilicus N that is used in reference to the body 20 of leting others have a look at.Umbilicus position indicator 118 is through holes that (but being not limited to) is formed on the centre of supporting member 114.Can see that by umbilicus position indicator 118 mode of umbilicus N is next with respect to human body 20 positioning support spares 114 according to making.Positioning support spare 114 makes it possible to accurately measure abdominal part width value Wsbj in this way, and does not have the error that is caused by the mistake location.Like this, umbilicus position indicator 118, horizontal adjustment auxiliary unit 119 and contact site 120 assist operator accurately are positioned at the position that can highly reproducibly measure waistline with waistline accountant 101, and this position is on the residing outside of umbilicus N.
As shown in Figure 9, driving mechanism 7c is arranged on the supporting member 114, is used for pick off 6c is moved in a scope with respect to supporting member 114.The type of the driving mechanism that is adopted is identical with type in first embodiment.By means of driving mechanism 7c, pick off 6c is moved horizontally, shown in the dotted line among Figure 10 and Figure 11 along supporting member 114 (that is, along with floor or bed 30 parallel directions).
During pick off 6c moves horizontally, one pick off 6c measures apart from a plurality of space D C of a plurality of measuring positions on a plurality of parallel vertical slotted lines on the same vertical plane, and each spacing is between the sensing station and the measuring position on bed 30 or the human body 20 of pick off 6c.
Under state shown in Figure 10, pick off 6c measure itself and and the crossing bed 30 of vertical survey line (from the path of the light beam of pick off 6c) between space D C.Space D C under this state is the altitude datum ELE of pick off 6c no better than, and ELE is the vertical dimension between the bottom of pick off 6c and supporting leg 3a and 3b.On the other hand, under state shown in Figure 11, another space D C between the crossing object's position of that pick off 6c measures itself and human body 20 and another vertical survey line (from the path of the light beam of pick off 6c).
Be appreciated that from Figure 10 the space D C that records is very big when pick off 6c is not in human body 20 tops.Otherwise as shown in figure 11, when pick off 6c was positioned at human body 20 tops, the space D C that records was less.Therefore, can be based on two end SE that relatively come human body 20 and TE to the size of space D C and at least one threshold value, and can estimate at two the end SE of human body 20 and the abdominal part width value Wsbj of the human body 20 between the TE.This is the General Principle that device 101 is realized the abdominal part width measure.When the horizontal range that reduces the vertical survey line at interval and when increasing the quantity of the spacing of measuring, can improve estimated accuracy to abdominal part width value Wsbj.
With reference to the block diagram of Figure 12, will the electric structure of waistline accountant 101 be described.Fig. 4 of the block diagram among Figure 12 and first embodiment is similar, but in Figure 12, that be electrically connected with microcomputer 8 is pick off 6c and driving mechanism 7c, rather than pick off 6a and 6b and driving mechanism 7a and 7b.In addition, do not use electrode 15 and umbilicus position indicator 18.
Replace control pick off 6a and 6b to be used for range finding and control driving mechanism 7a and 7b and be used for movable sensor 6a and 6b, controller 9 control pick off 6c are used for measuring distance DC and control driving mechanism 7c is used for movable sensor 6c.

With reference to the flow chart shown in Figure 13 A and Figure 13 B, will using and operating of waistline accountant 101 be described in more detail.The step of being carried out by microcomputer 8 in the operation of this flow chart is corresponding to being stored in the computer program in memorizer 12 or another memorizer or the storage device or the element of computer program.Step S51, S52 and S53 after the energising is identical with step S1, S2 and S3 among Fig. 6 of first embodiment, so they is not described in detail.Yet, at step S53, the position of 8 couples of pick off 6c of microcomputer rather than the position of pick off 6a and 6b carried out initialization.In addition, functionally or physically be provided with enumerator in microcomputer 8, the number of times that is used for space D C being sampled to above pick off 6c is positioned at human body 20 time is counted.At step S53,, Counter Value " i " is reset to zero (default value) in order to carry out system initialization.
At step S54, microcomputer 8 as controller 9 with start sensor 6c, thereby pick off 6c measure its with beds 30 between initial vertical interval.Microcomputer 8 obtains this initial vertical interval thus and it is stored in the memorizer 12 benchmark elemental height ELE as pick off 6c.
At step S55, microcomputer 8 is pressed constant speed movable sensor 6c as controller 9 with control driving mechanism 7c.As a result, pick off 6c measures one of (sampling) space D C.Be appreciated that when processing turns back to step S55 according to this flow chart, pick off 6c just be moved and by starting measuring next space D C, thereby scan human body 20 with certain sampling time interval.
At step S56, computer 10 calculates poor between last spacing of measuring and the benchmark elemental height ELE.At step S57, microcomputer 8 is used for determining as determiner 11 whether the vertical survey line of pick off 6c is positioned at human body 20 tops.This is determined by determining whether above-mentioned counter values " i " is equal to or greater than 1 and realizes.
If " i " less than 1 (pick off 6c is not above human body 20), then handles and proceed to step S58, at step S58, determiner 11 is used for determining as the end detector whether the slotted line of pick off 6c arrives first end (beginning end) SE of human body 20.This determine by the difference that relatively in step S56, calculates be stored in that threshold value P in the memorizer 12 realizes.If should be poor greater than P, then the slotted line of pick off 6c have arrived beginning end SE.Should determine with following determine identical: when pick off 6c measured space D C less than another threshold value, determiner 11 definite pick off 6c had arrived the beginning end SE of human body 20.
If (this difference is not more than P) that determining in step S58 negated then handled and turned back to step S55,, next space D C is sampled at step S55.If determining in step S58 is sure (this difference is greater than P), then handle and proceed to step S59, at step S59, microcomputer 8 increases progressively 1 with Counter Value " i ".
If counter values " i " is equal to or greater than 1, then determining in step S57 is sure, and handles and to be directly to step S59 (without step S58), just advances above human body 20 because pick off 6c has known in system.
At step S60, determiner 11 is used for determining as the end detector whether the slotted line of pick off 6c arrives the second end (final end) TE of human body 20.This determine by the difference that relatively in step S56, calculates be stored in that threshold value Q in the memorizer 12 realizes.Threshold value Q can be identical or different with above-mentioned threshold value P.If this difference is equal to or less than Q, then the slotted line of pick off 6c has arrived final end TE.Should determine with following determine identical: when pick off 6c measured space D C greater than another threshold value, determiner 11 definite pick off 6c had arrived the final end TE of human body 20.
If (this difference is greater than Q) that determining in step S60 negated then handles and turn back to step S55, at step S55, next space D C is sampled, because pick off 6c still advances above human body 20.
If determining in step S60 is sure (this difference is not more than Q), then handle and proceed to step S61, at step S61, controller 9 is measured spacing and is stopped driving mechanism 7c movable sensor 6c as measuring terminator (that is, measuring the termination device) and stopping pick off 6c.In addition, microcomputer 8 keeps the current numerical value " i " of sample counter, then based on this numerical value, computer 10 is as distance calculator and calculate and detect the sensing station of first end SE and detect gap length Lint (in Figure 11) between the sensing station of the second end TE.This gap length Lint equals the abdominal part width value Wsbj between first end SE and the second end TE.Realize calculating by sampled distance being multiply by at interval counter values " i " to gap length Lint, wherein sampled distance be at interval the sampling period at interval with the product of the gait of march of pick off 6c.Computer 10 is stored in abdominal part width value Wsbj (Lint) in the memorizer 12.
At step S62, microcomputer 8 reads above-mentioned regression formula (that is the correlation between abdominal part width value and the waistline) from memorizer 12.
At step S63, microcomputer 8 is as computer 10 (waistline computer), is used for calculating based on the abdominal part width value Wsbj (X of regression formula) of this regression formula and the human body 20 that calculates the waistline Y of human body 20.Computer 10 is stored in waistline Y in the memorizer 12.At step S64, microcomputer 8 serves as display controller, is used for making display 4 to show the waistline that is stored in memorizer 12.After step S64, be used to calculate the processing end of waistline.
In the above-described 2nd embodiment, show the supporting member 114 of rod.Yet the shape of supporting member 114 is not limited thereto.For example, replace the supporting member 114 in second embodiment, can adopt similar to the supporting member 14 in first embodiment to be roughly rectangle and the open frame in one of them limit.
In the above-described 2nd embodiment, come counting period length L int based on sample counter numerical value " i ".Yet, be not intended to limit the invention to present embodiment.In an alternative embodiment, can in driving mechanism 7c, incorporate the range encoder (not shown) into and measure gap length Lint.When determiner 11 when this range encoder notice pick off 6c has arrived first end SE, this encoder begins to measure described length.When determiner 11 when this range encoder notice pick off 6c has arrived the second end TE, this encoder stops measuring length L int.
Because benchmark elemental height ELE is the vertical dimension between the bottom of pick off 6c and supporting leg 3a and 3b, so needn't measure above-mentioned initial vertical interval in practice.Therefore, can in advance benchmark elemental height ELE be stored in the memorizer 12.
In the above-described 2nd embodiment, first end and the second end are based on the space D C that records and are definite.Yet, in an alternative embodiment, determiner 11 (end detector) can determine that pick off 6c has arrived first end SE when pick off 6c output error signal, and determines that pick off 6c has arrived the second end TE during output error signal once more at pick off 6c.This alternative embodiment is being favourable under the following situation: the datum water level that is fit to that does not all have to measure the initial vertical interval from pick off to it in the mobile range of pick off 6c in each side of human body 20.According to this alternative embodiment, can not use benchmark elemental height ELE and described threshold value.
In another alternative embodiment (not shown), the operator can manually move pick off 6c when pick off 6c samples to space D C at interval with certain sampled distance with respect to frame 14.
In another alternative embodiment shown in Figure 14, the measuring unit of waistline accountant 101A comprises a plurality of contactless distance measuring sensor 6c that is fixedly supported upon on the supporting member 114.These pick offs 6c equidistantly separates each other, and measures apart from a plurality of space D C of a plurality of measuring positions on many vertical parallel slotted lines respectively.In this embodiment, thereby, pick off 6c do not need above-mentioned driving mechanism 7c, so can easily make this device because being fixed to supporting member 114.In addition, because do not need movable sensor 6c automatically or manually, so simplified use to this device.When the quantity of pick off increases, can improve estimated accuracy to abdominal part width value Wsbj.
