Summary of the invention

But, the information of body fat is especially paid close attention to the serviceability of diseases due to habit disturbances such as screening diabetes, hypertension and blood hyperlipemia, about visceral adipose tissue, subcutaneus adipose tissue near the organs and tissues in adhering to, being accumulated in, the importance of its measurement uprises day by day

Particularly, visceral adipose tissue is near the fatty tissue of concentrating the abdominal part be distributed in trunk, according to being judged by the cross-sectional area of the fatty tissue of the abdominal part sectional view picture of bats such as X line CT, MRI.But device volume is big, and in addition, existing irradiated problem also has the expense aspect under the situation that is the X line, is unsuitable for open-air and home-use measurement.Therefore, visceral adipose tissue normally according to organizing dependency or organize dependency to estimate with the degrease of whole body with total body fat, even as screening, can not be guaranteed sufficient reliability.

Recently, also developing following method: the umbilicus at trunk encloses the circumferential arrangement electrode, measures the internal driving of trunk and estimates visceral adipose tissue information.But this method is based on the method that has effective dependency between skeletal muscle tissue layer, subcutaneus adipose tissue layer and the visceral adipose tissue, if will can catch the information of any tissue then can estimate that general information is as prerequisite.Therefore, subjects for the high health of the independence that may have very significant dependency, can expect to obtain good result, but for the different object person of dependency between each tissue, for example visceral adipose tissue significantly loose and with the significantly low subjects's of the dependency of subcutaneus adipose tissue layer, skeletal muscle tissue layer measurement result, will comprise big error.That is to say, even in the method that this is being developed, can think so long as the subjects of the healthy life of can supporting oneself, the umbilical part entire circumference where configured electrodes can both be measured, but when to paralysis/can not self-care person wait, the very big problem of existence when particularly the patient of recumbency measures in bed.

In addition, method in this exploitation makes as the energising of the tissue site of determination object, obtains on the resistance value this point related with interior tissue and can be called high-tech applying from the abdominal surface electric current, but practical situation is because as the problem in the internal structure of the trunk of measuring the position, determined impedance information itself has useful sensitivity hardly to visceral adipose tissue.Promptly, as the trunk of measuring the position is tubbiness, multiple structure, that is to say it is following structure: organize with interior organs and tissues, spine as the visceral adipose tissue of determination object to be presented the very skeletal muscle tissue layer covering of good electrical conductivity, and this skeletal muscle tissue layer is covered by the subcutaneus adipose tissue layer of the non-constant of electric conductivity.Particularly, visceral adipose tissue periphery as determination object, electric conductivity is than the interior organs and tissues of skeletal muscle tissue layer difference and to adhere to, put aside the visceral adipose tissue of structural poorly conductive of internal organs in this dominant and be the structure of complexity, therefore, compared with the skeletal muscle tissue layer, inner electric conductivity becomes and is on duty mutually.Therefore, be configured in around the abdomen even merely electric current is applied electrode, its major part becomes the energising by the skeletal muscle tissue layer, and electric current distribution can be observed from the surface measurement electrode also as dominant Potential distribution in the skeletal muscle tissue layer.And, applying the surface area of electrode or apply distribution of current density by electric current by the decision of the electrode width of abdomen peripheral direction, the information observation in the high spreading resistance zone of the electric current density in the subcutaneus adipose tissue layer under electrode is dominant.

Furtherly, because as the trunk tubbiness of measuring the position, the electric current density that electric current applies under the electrode concentrates the sensitivity in (spreading resistance) regional subcutaneus adipose tissue layer to uprise, and skeletal muscle tissue is compared electric conductivity with fatty tissue quite high, therefore, the major part of having taked to pass through the electric current of subcutaneus adipose tissue layer turns back to the path that applies the electrode side across the relative electric current of skeletal muscle tissue layer by the subcutaneus adipose tissue layer, its result, the distortion significantly in this skeletal muscle tissue layer of the Potential distribution in the inside.Thereby, in the conventional method, the current potential major part of measuring is the information of subcutaneus adipose tissue layer, almost can not expect to as the visceral adipose tissue of determination object, be inside organs and tissues and adhere to, be accumulated in visceral adipose tissue energising around it, can only catch the extremely low information of measurement sensitivity below 10% in whole impedance measurement interval.

In order to avoid these problems, also can consider to prevent the method that this estimation difference enlarges by amassing the long substitution estimator of the high abdominal circumference of dependency with the subcutaneus adipose tissue aspect, but this method is eventually just according to the indirect Estimation of dependency between structure organization, is the measurement method of the energising sensitivity of guaranteeing that abdominal part central authorities are required hardly.That is to say, can't guarantee to depart from each individual error of statistical correlation design, particularly unsound situation, intermediary skeletal muscle tissue layer subcutaneous, that visceral adipose tissue is many be many/few situation etc., may produce significant error.In addition, the subcutaneus adipose tissue aspect is long-pending to be that the subcutaneus adipose tissue layer is outermost configuration because people's trunk is the arrangement design of organizing on the concentric circular with abdominal circumference long correlation height, therefore, and long and its area of the thick decision of subcutaneus adipose tissue by the outside.

Four electrode method is also used in electrode configuration on trunk usually.This method applies electric current in subjects's body, and, measure by applying electric current and measure the interval potential difference that produces in position the subjects, measure measuring the interval organism electrical impedance in position.When four electrode method is applied to the mensuration position of the tubbiness as the trunk, it for example is under electric current applies electrode that the electric current density that electric current begins to expand is concentrated (being the spreading resistance zone), therefore near the subcutaneus adipose tissue layer, produce big potential difference, occupy major part in the potential difference of voltage measurement electrodes measurements.In order to reduce the influence of this spreading resistance, adopt and guarantee that fully the configuration that electric current applies distance between electrode and voltage measurement electrodes is important.In general mensuration, measure interval long and can fully guarantee to measure under the condition of distance between voltage measurement electrodes, therefore, should fully guarantee so-called S/N sensitivity (N is that influence (noise), the S of spreading resistance is the signal at the voltage electrode measurements).But, under the situation at the mensuration position of tubbiness, in order to reduce N as the trunk, guarantee from electric current apply the distance of electrode and make voltage measurement electrodes away from the time, on the contrary, the voltage measurement electrodes zone distance diminishes, its as a result S diminish S/N variation as a result.And the spreading resistance portion that electric current density is high is a subcutaneus adipose tissue layer portion, because the subjects of the lipophilia of thickness is normally arranged, therefore becomes sizable N, and S/N is variation doubly.Like this, can infer: when four electrode method is used at the mensuration position of the tubbiness as the trunk,, be difficult to guarantee useful S/N sensitivity visceral adipose tissue only by enclose configured electrodes on week at umbilicus.In addition, about S/N, in explanation, further describe for embodiment described later.

Therefore, dispose at the trunk abdominal part of determination object under the situation of actinobolia of whole four electrodes, can consider to apply electrode, perhaps for the skeletal muscle tissue layer is limited the electrode configuration as conductive layer at the conductive layer window portion configuration electric current as aponeurosis (aponeuroses) portion of avoiding the skeletal muscle tissue layer.But electrode configuration this moment error becomes to measuring precision brings the main cause that has a strong impact on.

In addition, at extremity beyond the trunk abdominal part of as far as possible the electrode configuration being shifted to determination object etc. (by in the configured electrodes from the position that trunk is given prominence to as extremity, extremity are thought of as the actinobolia that substitutes from the lead-in wire of trunk) in, realize alleviating of above-mentioned restriction, on the contrary, owing to, can not fully freely select the determination object position of trunk abdominal part from the restriction of the outstanding extremity arrangement of trunk.

The objective of the invention is to solve these the problems of the prior art points, even provide a kind of at poorly conductive interior organs and tissues and the zone of visceral adipose tissue in also guarantee to measure required sensitivity, only just can measure the fatty tissue that is accumulated in trunk, the fatty tissue of particularly adhering to/being accumulated in interior organs and tissues periphery and method and the device that is accumulated in the subcutaneus adipose tissue layer information of hypodermic layer simultaneously by switching.

The specific embodiment

Before describing embodiments of the present invention and embodiment in detail, the measuring principle of the visceral adipose tissue amount of trunk of the present invention is described.The present invention uses the organism impedance information and the health specialization information of each part that is obtained by upper limb (arm), lower limb (lower limb), trunk extremity actinobolia such as (trunk middle parts) basically, can estimate the ratio (V/S) of visceral adipose tissue information (cross-sectional area amount, volume or weight), trunk visceral adipose tissue amount and subcutaneus adipose tissue amount of trunk abdominal part (middle part) and the total adipose tissue mass (trunk stomach fat tissue mass) of subcutaneus adipose tissue amount and visceral adipose tissue amount.

Furtherly, the present invention relates to measure the fatty tissue that is accumulated in trunk easily with high accuracy, particularly adhere to, be accumulated in the method etc. of visceral adipose tissue information of organs and tissues periphery.

Particularly, the present invention can measure the subcutaneus adipose tissue layer information that in the fatty tissue that is accumulated in trunk, particularly is accumulated in hypodermic layer easily with high accuracy.That is,, need the metrical information of abdominal circumference girth and subcutaneus adipose tissue thickness for subcutaneus adipose tissue amount, particularly the cross-sectional area amount (CSA) of calculating trunk.Can guarantee abdominal circumference girth or abdominal part width, thickness etc. by actual measurement, but subcutaneus adipose tissue thickness is different and different according to the position of abdominal circumference on week, individual variation is many.Therefore, importantly determine to measure to estimating the subcutaneus adipose tissue high position of amount serviceability.And, when estimating volume, can calculate by the length information that above-mentioned CSA be multiply by the trunk abdominal part as the subcutaneus adipose tissue amount of abdominal part.Owing to, therefore can estimate trunk abdominal part length by health specialization information with the dependency height of height.

In other words, particularly, the present invention can carry out high-precision estimation by using abdominal circumference girth information and the specific high subcutaneus adipose tissue thickness information of contribution when estimating that trunk abdominal part umbilicus encloses the subcutaneus adipose tissue amount (CSA) at week place.At this moment, abdominal circumference girth information is except the abdominal circumference girth, and abdominal part width or thickness information that umbilicus encloses the portion place also can become useful estimation variable information.According to the multiple recurrence of health specialization information (height H, body weight W, sex SEX, age Age etc.), can guarantee the abdominal circumference girth information that reliability is high by also.

The present invention uses following method for this reason.

(1) uses based on series-parallel equivalent-circuit model of skeletal muscle tissue layer, interior organs and tissues and visceral adipose tissue and suppose organizational information in the organism electrical impedance information that is included in the trunk abdominal part.Interior organs and tissues and visceral adipose tissue are considered to series connection.(thereby, can be by the size of visceral adipose tissue, the variation of prediction energising amount).

(2) in addition, when abdominal circumference length can be guaranteed as health specialization information, as the high accuracy model that the subcutaneus adipose tissue layer is also contained in the equivalent-circuit model, use based on series-parallel equivalent-circuit model of subcutaneus adipose tissue layer, skeletal muscle tissue layer, interior organs and tissues and visceral adipose tissue and suppose.

(3) the subcutaneus adipose tissue amount is estimated to be made of the multiple recursion that the abdominal circumference length in the health specialization information is made as main explanatory variable.And, with abdominal circumference long square be made as main explanatory variable.According to ad hoc approach of the present invention, when obtaining dominant trait ground and have the trunk impedance of bed thickness information of subcutaneus adipose tissue layer, this trunk impedance and abdominal circumference long (first power) long-pending is made as main explanatory variable.

(4) use the organism electrical impedance information and the health specialization information of each part that the extremity actinobolia by upper limb (arm), lower limb (lower limb) obtains, obtain the skeletal muscle tissue layer information of trunk abdominal part (middle part), be used to be identified for not definite information that visceral adipose tissue information is estimated.

(5) the definite of interior internal organs organizational information is made of the multiple recursion that the height information in the health specialization information is made as main explanatory variable, is used to be identified for definite information that visceral adipose tissue information is estimated.

(6) can be used to comfortable umbilicus position place X line CT faultage image organize cross-sectional area (CSA:Cross-Section Area (cross-sectional area)), according to the CSA of MRI method and the use in the trunk abdominal part integral body tissue volume amount of DEXA method, MRI method (to the Integral Processing of each section of length direction), weight (can be by according to tissue density's information of studying in advance, calculate from the conversion of volume to weight), the benchmark of organizing that is implemented in multiple recursive analysis (the inspection amount line creating method) use that is used for each tissue of quantification is measured.In the DEXA method, can carry out benchmark to total fatty tissue information of the total of abdominal visceral fat tissue and subcutaneus adipose tissue layer and measure.

(7) in order to use aforesaid method to catch the information of visceral adipose tissue accurately, need to be replaced into the method for certain condition value by the change of breathing the measurement impedance information that waits the trunk that causes, with the impedance measurement sampling period be made as the general breathing cycle 1/2 in, monitor respiratory variations by the time sequence, in maximum and the minima of each judgement breathing cycle breathing cycle and each breathing cycle, can catch the quiet intermediate value of breathing.

(8) and, also can be according to measuring impedance information, carry out the pre-incident survey of the bad influence that brings by storing of diet before measuring and bladder urine etc.Usually, the resistance value of trunk abdominal part in the common subjects colony of health, the information of dominant trait ground reflection skeletal muscle tissue layer.In addition, the information of the skeletal muscle tissue layer of trunk is very little as measured value, to there not being big difference between each individual.Reason is: owing to be the high design of dependency of the antigravity muscle of prosperity with conducting oneself with dignity in the terrestrial gravitation lower support, therefore, particularly not being subjected to the subjects of gravity effect except recumbency or applying the special colony of the project player etc. of stress of deadweight several times, almost is to be determined by body size.Thereby the estimation of the skeletal muscle tissue amount of aforementioned trunk abdominal part can expect to obtain measuring the good achievement of sensitivity from the appendicular skeleton muscular tissue.At this, except skeletal muscle tissue and aforementioned breathing change, to the impedance influences of trunk abdominal part big be the bad influence that brings by storing of diet and bladder urine etc.Thus, collect the resistance value at trunk middle part as population data, during from meansigma methods [mean] and deviation [SD], the influence that is brought by storing of urinating of diet and bladder etc. is in the scope above 2SD as can be known.During accurate general groups such as not excessive consideration player to a certain degree, by with 3SD as standard, can carry out the screening of this influence.

(9) and, determining of the variation portion that causes by local inflammation of the skeletal muscle tissue layer of trunk abdominal part and interior organs and tissues, also can be by relatively from the trunk abdominal part resistance value of the different actinobolia of the electrical path of extremity actinobolia (four kinds), carry out determining to a certain degree.Thereby, the situation inspection of organs and tissues or skeletal muscle tissue layer in can also carrying out from the angle of the body fluid changes in distribution of trunk abdominal part that diseases such as inflammation are arranged.

Describe measuring principle of the present invention below in order in detail based on foregoing method.

1. the trunk consideration method of dividing

When being top/middle part/bottom with torso portion (1), the relation of the prosperity of skeletal muscle tissue is as follows.

(a) the dependency height of trunk top and upper limb portion is particularly with the dependency height of the skeletal muscle tissue of the upper arm of peri position upper arm parts.

(b) the dependency height of lower torso and lower limb portion is particularly with the dependency height of the skeletal muscle tissue of peri position huckle.

(c) the dependency height of the huckle skeletal muscle tissue of trunk middle part and lower limb portion (bigger) because conducts such as the big psoas muscle of the huckle of control lower limb portion, iliposoas muscle occupy skeletal muscle tissue.

(2) skeletal muscle tissue at trunk middle part (abdominal part) is made of abdominal muscles group and dorsal muscles group, and they have the flourishing function as the junction of upper limb and lower limb (left rotation and right rotation action or flexor forwards, backwards etc.).

2. according to the estimation of the trunk of extremity portion middle part skeletal muscle tissue

(3) therefore, the skeletal muscle tissue prosperity (tissue mass) at trunk middle part has confidential relation with the prosperity of the skeletal muscle tissue of upper and lower extremities portion.That is, can estimate the skeletal muscle tissue amount at trunk middle part according to the skeletal muscle tissue amount of upper and lower extremities portion.Trunk middle part skeletal muscle tissue amount is made as the subordinate variable, upper limb portion skeletal muscle tissue amount and lower limb portion skeletal muscle tissue amount are arranged to separately independently explanatory variable, form multiple recursion, thereby, can estimate the skeletal muscle tissue amount at trunk middle part.

Trunk middle part skeletal muscle tissue amount [MMtm]=a0 * lower limb skeletons muscular tissue amount [MMl]+b0 * upper limb skeletal muscle tissue amount [MMu]+c0 ... formula 1

At this, a0, b0, c0 are recursion coefficient, are constants.

(4) in addition, from before research as can be known, about the skeletal muscle tissue amount of extremity,, can carry out the estimation of skeletal muscle tissue amount according to measuring interval impedance measurements and this siding-to-siding block length information.

Lower limb skeletons muscular tissue amount [MMl]=a1 * Ll ²/ Zl+b1 ... formula 2

Upper limb skeletal muscle tissue amount [MMu]=a2 * Lu ²/ Zu+b2 ... formula 3

At this, a1, a2, b1, b2 are recursion coefficient, are constants.Ll is the length of lower limb, and Lu is the length of upper limb portion, and Zl is the resistance value of lower limb portion, and Zu is the resistance value of upper limb portion.

(5) if common object person then also can estimate extremity long (particularly, pressing the height information serviceability height of sex) by health (individual) specialization information such as height, body weight, sex, ages

(6) similarly, variable as an illustration, also upwards the estimator of the skeletal muscle tissue amount of lower limb portion and trunk middle part skeletal muscle tissue amount adds health specialization information such as sex, age, body weight, thereby, also can proofread and correct some variations by the matter of growing flourishing and nervous system that age growth brings and tissue with adding up.

(7) in addition, the mensuration of the reference side when making multiple recurrence estimator is used the skeletal muscle tissue amount of obtaining by MRI method, DEXA method.

(8) in addition, as the simpler method that can expect to improve precision is following method: except obtain trunk and extremity long letter breath by mensuration, when estimating trunk and extremity long letter breath, the impedance information of extremity portion is directly added the estimator of trunk middle part skeletal muscle tissue amount according to health specialization information such as heights.

Trunk middle part skeletal muscle tissue amount [MMtm]=a3 * H ²/ Zl+b3 * H ²/ Zu+c3

... formula 4

At this, a3, b3, c3 are recursion coefficient, are constants.H is a height, and Zl is the resistance value of lower limb portion, and Zu is the resistance value of upper limb portion.

(9) as the method that can expect further to improve precision, when further obtaining stem length information, consider the distortion of estimator as described below by mensuration.

For formula 1～3,

(10) when expectation further improves precision, there is shortcoming, but the method for using extremity peri position portion information is arranged the contained property increase of measuring (diminishing simplicity).By voltage measurement electrodes is contacted or is attached on the knee joint elbow, can enoughly measure identical extremity actinobolia and measure with extremity.That is, owing to compare with lower limb or upper limb information from amphi position, the information conduct of the peri position portion except that amphi position portion and the related information of the skeletal muscle tissue at trunk middle part, serviceability is higher.That is, upper arm (upper limb peri position) has big dependency with trunk top, and thigh (lower limb peri position) has big dependency with lower torso, also has useful relation between the trunk upper, middle and lower.Therefore,, measure huckle skeletal muscle tissue amount, upper arm parts skeletal muscle tissue amount and be used for the estimation approach of the skeletal muscle tissue amount in the middle part of the trunk, also can make estimator with order same as described above for upper and lower extremities portion skeletal muscle tissue amount.

(11) conduct has following consideration method for the example of the consideration method of the skeletal muscle tissue of trunk:

(a) the trunk upper and lower since with the dependency height of upper limb portion and lower limb portion, regard top as upper limb portion, regard the bottom as lower limb portion.

(b) the trunk upper and lower is combined with the trunk middle part, regard trunk as.No matter be which method, the object person is arranged to common healthy people or the scope that can support oneself live approaching with it, thereby, the dependency height that each is mutual, therefore any consideration method big difference can not occur.

3. trunk constitutes the electrical equivalent circuit modelling of tissue

(12) impedance of the trunk of obtaining by the extremity actinobolia is the information at trunk middle part.About this impedance, in explanation, be described in detail embodiment described later.

(13) can think that trunk mainly constitutes by subcutaneus adipose tissue layer, skeletal muscle tissue layer (abdominal muscles group, dorsal muscles group), interior organs and tissues with attached to the visceral adipose tissue in its gap.Osseous tissue not being enumerated as constituting tissue, is because the dependency of the amount of osseous tissue and skeletal muscle tissue layer is very high, can consider as the organizer of one.Specific insulation also comprises myeloid tissue etc. in vivo, thereby electric conductivity is fairly good, can think to have characteristic near skeletal muscle tissue layer or interior organs and tissues.Thereby, represent these four when organizing with electric equivalent-circuit model, organs and tissues and visceral adipose tissue in series constituting, subcutaneus adipose tissue layer and skeletal muscle tissue layer constitute in parallel with this placed in-line complex tissue layer respectively.About this equivalence circuit model, will in explanation, be described in detail embodiment described later.According to this model, for the energising to the trunk length direction, stream has dominant electric current in the skeletal muscle tissue layer.Visceral adipose tissue is because in the peripheral clearance attached to interior organs and tissues, therefore when not having visceral adipose tissue or visceral adipose tissue after a little while, interior organs and tissues presents the electric conductivity near skeletal muscle tissue, therefore, electric current is energized to interior internal organs tissue sides.In addition, visceral adipose tissue is many more, reduces more to the energising amount as the complex tissue layer of the complex of interior organs and tissues and visceral adipose tissue.Modular form when representing the measurement impedance at trunk middle part and constituting its four to organize with equivalent-circuit model can be expressed as follows.

Ztm=ZFS//ZMM//(ZVM+ZFV) ... formula 6

At this,

The whole impedance in trunk middle part: Ztm

The impedance of subcutaneus adipose tissue layer: the ZFS... specific insulation is big.

The impedance of skeletal muscle tissue layer: the ZMM... specific insulation is little.

The impedance of interior organs and tissues: ZVM... thinks near the specific insulation of skeletal muscle tissue layer.

The impedance of visceral adipose tissue: ZFV... thinks that specific insulation equates with subcutaneus adipose tissue or is littler than it a little.The synthetic decomposition of fatty tissue is faster than subcutaneus adipose tissue, thinks that therefore interior blood vessel of tissue and blood flow volume are many.

And it is with the electrical characteristic between impedance decision tissue, not as determine the electrical characteristic between tissue with specific insulation ρ [Ω m].According to last relation of plane, usually in order to concern the electrical characteristic value of each tissue of explanation down.

ρ?MM<<ρ(VM+FV)<ρ?FS

ρ?VM<<ρ?FV

ρ MM=ρ VM, perhaps ρ MM＜ρ VM

ρ FV=ρ FS, perhaps ρ FV＜ρ FS

At this,

The specific insulation of subcutaneus adipose tissue layer: ρ FS

The specific insulation of the interior organs and tissues of skeletal muscle tissue layer inboard and the complex tissue layer of visceral adipose tissue: ρ (VM+FV)

The specific insulation of skeletal muscle tissue layer: ρ MM

Therefore, the comparison of the electrical characteristic between each tissue is as follows.

Fig. 6 is the figure that schematically shows trunk abdominal part (middle part) structure, and the tissue that constitutes the trunk abdominal part may be thought of as subcutaneus adipose tissue layer (FS), skeletal muscle tissue layer (MM), interior organs and tissues (VM), attached to the visceral adipose tissue between its crack (FV).When trunk is switched on, can think that most electric current switches on to the skeletal muscle tissue layer.Because the electric conductance of skeletal muscle tissue layer is electrically organized than other.Organs and tissues is connected with visceral adipose tissue in thinking, can predict the variation of energising amount as can be known according to the size of visceral adipose tissue.

Fig. 7 is the figure that the structural table of the trunk abdominal part of Fig. 6 is shown electrical equivalent circuit, showing and omit the simplification trunk abdominal part equivalent circuit that the subcutaneus adipose tissue layer is considered, is the trunk abdominal part equivalent circuit of considering with the method for the method 1 in the preceding paragraph " 3. trunk constitutes the electrical equivalent circuit modelling of tissue " (14).In addition, Fig. 8 is the figure that equally the trunk abdominal part structural table of Fig. 6 is shown electrical equivalent circuit, showing and do not omit the trunk abdominal part equivalent circuit that the subcutaneus adipose tissue layer is considered, is the trunk abdominal part equivalent circuit of considering with the method for the method 2 in the preceding paragraph " 3. trunk constitutes the electrical equivalent circuit modelling of tissue " (15).In addition, the symbol that in these figure, uses as previously mentioned, Ztm represents the impedance that trunk middle part is whole, ZFS represents the impedance of subcutaneus adipose tissue layer, ZMM represents the impedance of skeletal muscle tissue layer, the impedance of organs and tissues in ZVM represents, and ZFV represents the impedance of visceral adipose tissue.And, as previously mentioned, in the equivalent circuit of Fig. 7,

Relational expression set up, in the equivalent circuit of Fig. 8,

Relational expression set up.

＜subcutaneous fat is measured or the selection of subcutaneous fat and interior fat is measured 〉

Particularly explanation is used for the technology that subcutaneous fat is measured or the selection of subcutaneous fat and interior fat is measured.

Fig. 9 carries out modeled figure with the sketch map of trunk shown in Figure 6 with the abdominal circumference week cross section of umbilicus height.As shown in the drawing, the trunk cross section comprises: be positioned at outermost subcutaneus adipose tissue layer (FS), be positioned at the inboard skeletal muscle tissue layer (MM) of its next-door neighbour, the visceral adipose tissue (FV) that is positioned at the most inboard organs and tissues (VM) and surrounds it.

Figure 10 is the figure that the sketch map of Fig. 9 further is expressed as electrical equivalent circuit.For example, apply electric current (I) among electrode 10e, the 10f when applying at electric current, when measuring potential difference (V) by

current measurement electrode

11e, 11f, near the impedance (ZFV1, ZFV2) of the visceral adipose tissue about near the impedance (ZFS1, ZFS2) of the subcutaneus adipose tissue layer the resistance in this equivalence circuit mainly shows as before and after the umbilicus, the impedance (ZFS0) of the subcutaneus adipose tissue layer around the abdomen, umbilicus before and after the impedance (ZMM1, ZMM2) of the skeletal muscle tissue layer of each side and the umbilicus also shows as near the impedance (ZVM) of the interior organs and tissues the trunk center.

Figure 11 represents further to simplify the circuit of Figure 10.Owing to think that ZFS1 and ZFS2 are roughly the same sizes, at this they are expressed as the ZFS of identical value, in addition, ZMM1 and ZMM2 or ZFV1 and ZFV2 are expressed as ZMM, ZFV respectively.In addition, omitted and thought electric conductivity than being starkly lower than other regional ZFS0.Can omit its this point, can clearly learn according to the record of preceding paragraph " 3. trunk constitutes the electrical equivalent circuit modelling of tissue " (13).

Below with reference to Figure 12 the interelectrode distance in the four electrode method and the relation of spreading resistance are described.Figure 12 is the figure of the relation of expression interelectrode distance and spreading resistance.Among the figure, with the part 30 expression spreading resistance zones of round dotted line.The electric current that applies electrode from electric current expands in subjects's the body after applying gradually, but the zone after just applying, is in the resistance region, does not expand so greatly, and therefore, electric current density is compared with other zones and become very high in these zones.Thereby when too closely disposing electric current and apply

electrode

10e, 10f and

voltage measurement electrodes

11e, 11f, the potential difference of measuring in

voltage measurement electrodes

11e, 11f is influenced by the very big of electric current in the resistance region.

For example, as as can be known by aforementioned formula 31, between the impedance (ZVM) of the impedance (ZFV) of the impedance (ZMM) of the impedance (ZFS0) of the subcutaneus adipose tissue layer around near the impedance (ZFS) of the subcutaneus adipose tissue layer the umbilicus and the abdomen, skeletal muscle tissue layer, visceral adipose tissue and near the interior organs and tissues the trunk center, there is following relation.

ZFS>>(ZVM+ZFV)>>ZMM

Therefore, almost do not have the liftoff potential difference measurement impedance ∑ Z1 of I-V electrode spacing, become as follows near when configuration.

Hence one can see that, because the influence of spreading resistance, ZFS is amplified to several times, therefore, dominant in the information of this ZFS.

Reduce the influence of spreading resistance, needs increasing electric current applies the distance between electrode and the voltage measurement electrodes.For example, the I-V interelectrode distance is guaranteed about 10cm and potential difference measurement impedance ∑ Z2 during configuration is as follows.

Obviously, by enlarging the I-V interelectrode distance, how many influences of spreading resistance diminishes, but only separates this degree, and the information of ZFS is still dominant.

In order to inquire in detail the influence of this spreading resistance, as shown in figure 13, consider to guarantee to be configured about 10cm so that between the I-V electrode among

electrode

11e, 11f, 11g, the 11h and between the V-V electrode phase mutual edge distance become situation about 1/3.But, establish

electrode

10e, 11e or

electrode

10f, 11h for almost there not being aforementioned I-V electrode spacing liftoff near configuration.The potential difference measurement impedance ∑ Z3 of this moment is as follows.

At this moment, the relation of measured voltage decline (potential difference) becomes as follows substantially between electrode.

V1＝I×ZMM//(ZVM+ZFV)

V2＝V3＝I×2×ZFS

10～20 the deviation of 1～2 or the N of S in the following formula is to be caused by the individual differences of the thickness of subcutaneus adipose tissue layer and the development degree of skeletal muscle tissue layer.From this result as can be known, even regulate interelectrode distance, also can guarantee sufficient S/N hardly.

In addition, because most of electric current is switched on dominantly, therefore, can not fully guarantee the energising sensitivity of the complex tissue layer of inside organs and tissues and visceral adipose tissue in the skeletal muscle tissue layer.That is, if the electric current of the skeletal muscle tissue layer of will flowing through is made as I1, will flow through is made as I2 as the interior organs and tissues of determination object and the electric current of visceral adipose tissue, then becomes as follows.

V1＝I×ZMM//(ZVM+ZFV)＝I1×ZMM＝I2×(ZVM+ZFV)

I＝I1+I2，

Thereby, become as follows.

Hence one can see that, promptly allows to get rid of the influence of spreading resistance, and in the electric current of the skeletal muscle tissue layer of flowing through also reaches and flows through 2～5 times of the electric current of organs and tissues and visceral adipose tissue, therefore, it is the further variation of S/N characteristic as a result.Like this, in the mensuration position of the tubbiness as the trunk, even adjust interelectrode distance, also because apply the interelectrode distance decision upper limit by electric current, therefore, the improvement of S/N characteristic is limited.

Figure 14 represents to be used for obtaining with the method identical with Fig. 6 an example of the electrode layout method of subcutaneus adipose tissue layer information.According to this electrode layout method, be not only subcutaneus adipose tissue layer information, measure visceral adipose tissue information in the time of can also be as the information of same that is separated from each other.Device of the present invention has the voltage measurement electrodes that is used to measure the voltage measurement electrodes of visceral adipose tissue and is used to measure the subcutaneus adipose tissue layer, by optionally switch these electrode configurations by switch unit, can measure visceral adipose tissue information and subcutaneus adipose tissue layer both information.The simultaneously-measured purpose of both sides is, to measure variable error main cause in the mensuration of breathing etc. etc. than breathing the fast sampling timing of change, by measure two mensuration simultaneously under equivalent environment, can relatively remove this error main cause.Thereby, except that breathing, also consider the influence that heart beating and other bodies are moving etc.Except that pick up speed, also can reach same purpose in the smoothing processing in same mensuration environment etc.

Figure 15 to Figure 18 shows the concrete electrode configuration example that is used to obtain subcutaneus adipose tissue layer information (not being visceral adipose tissue information).At this, Figure 15 is that expression is configured in the figure that electric current in the left and right sides aponeurosis (aponeuroses) portion 15 applies the impedance measurement configuration example of the subcutaneus adipose tissue layer under electrode 10e, the 10f, V2 represents right front sidepiece subcutaneus adipose tissue layer measurement potential difference, and V3 represents left front sidepiece subcutaneus adipose tissue layer measurement potential difference.Figure 16 is that expression is configured in the figure that near the electric current of the portion umbilicus A applies the impedance measurement configuration example of the subcutaneus adipose tissue layer under the electrode 10f, and V2 represents that the subcutaneus adipose tissue layer of portion is measured potential difference near the umbilicus.Figure 17 is the figure that electric current that expression is configured in umbilicus A bottom applies the impedance measurement configuration example of the subcutaneus adipose tissue layer under the electrode 10f, and V2 represents that the subcutaneus adipose tissue layer of umbilicus bottom measures potential difference.Figure 18 is that expression is configured in the impedance measurement configuration example that electric current in the flank portion 16 applies the subcutaneus adipose tissue layer under the electrode 10f, and V2 represents that the subcutaneus adipose tissue layer of flank portion 16 measures potential difference.

In order to obtain subcutaneus adipose tissue layer information (specifically, being current potential difference, resistance value), utilize spreading resistance at this.Spreading resistance is captured as undesirable impedance usually, but, particularly the spreading resistance that applies under the electrode of electric current can be represented the information relevant with the subcutaneus adipose tissue layer, therefore, can obtain useful subcutaneus adipose tissue layer information by measuring this regional potential difference.

In order to measure spreading resistance, possess: at least one electric current applies electrode pair; Can measure by apply from this electric current potential difference that electric current that electrode pair applies produces among the subjectss, at least one voltage measurement electrodes is right.At this, be included in electric current and apply a electric current in the electrode pair and apply electrode, for example electric current and apply electrode and be used as to the thin position of subcutaneus adipose tissue layer or to the thin position of the belly of muscle portion of belly of muscle portion that does not have the skeletal muscle tissue layer or skeletal muscle tissue layer and apply electric current, another electric current applies electrode, for example electric current and applies the position (perhaps subcutaneus adipose tissue layer determination object position) that electrode 10a is used as to the subcutaneus adipose tissue bed thickness and apply electric current.

On the other hand, be included in a voltage measurement electrodes 11e of voltage measurement electrodes centering, be configured in electric current and apply on the dominant position of influence of the spreading resistance under the electrode, promptly apply electrode and dispose near electric current.Relative therewith, another voltage measurement electrodes 11f, be configured in that electric current applies that the influence of the spreading resistance under the electrode alleviated away from the position on (applying electrode with respect to aforementioned currents) more than or equal to position near the triple distant place of the distance of a voltage measurement electrodes 11e configuration, promptly be configured in and be not subjected to or be difficult to be subjected to electric current to apply on the position that the subcutaneus adipose tissue layer under the electrode influences.Position as the former (one) voltage measurement electrodes 11e of configuration, for example have near trunk adheres to the umbilicus position of subcutaneus adipose tissue layer easily, the position of the very heavy back savings subcutaneus adipose tissue layer of flank portion (ilium rib rising wood), side back etc., reflection individual differences, as the configuration latter's the position of (another) voltage measurement electrodes 11f, for example be the position that is difficult to adhere to the fat tissue layer that reflects individual differences of near (the conjoint tendon membranous part of outer oblique abdominal muscle and rectus abdominis m.) etc. between umbilical part and the ilium rib rising wood, subcutaneus adipose tissue layer.Apply the configuration of the voltage measurement electrodes that electrode is provided with near electric current, electric current is applied electrode as full week at center on any position, also can catch identical information even be positioned at.For example, as shown in figure 15, each voltage measurement electrodes is applied on the position of electrode position being configured near the relative left and right sides electric current that with umbilicus and spine is central shaft, also can measure the subcutaneus adipose tissue layer of left and right sides sidepiece.

By apply from electric current electric current that electrode applies between voltage measurement is with

electrode

11e, 11f, voltage measurement is with potential difference measurement values that produce between electrode 11g, the 11h, potential difference V2, the V3 etc., can think proportional with impedance (ZFS) value of subcutaneus adipose tissue layer portion, also with the thickness (L of subcutaneus adipose tissue layer _FS) the proportional impedance information of information.If the impedance of spreading resistance portion is made as Δ Z, will be equivalent to the constant that electric current applies electrode area and be made as A0, then as follows.

ΔZ∝ZFS∝L _FS/A0∝L _FS

Therefore, the cross-sectional area amount AFS of subcutaneus adipose tissue layer can obtain by following formula.

AFS=Lw * L _FS=aa0 * ZFS * Lw+bb0 ... formula 45

In addition, in following formula, Lw is abdominal circumference length, is the abdomen circumference that aa0, bb0 are the constants of men and women's different value.

Obtain visceral adipose tissue information (current potential difference, resistance value etc.) for subcutaneus adipose tissue layer information of same the time, need be provided with the configuration different with the voltage electrode configuration that is used to measure subcutaneus adipose tissue layer information, another group voltage measurement electrodes is to (above result at least, in order to measure subcutaneus adipose tissue information and visceral adipose tissue both information simultaneously, need at least two voltage measurement electrodes to).

Figure 19 to Figure 22 represents to be used to measure the concrete electrode configuration example of subcutaneus adipose tissue layer information or while (optionally) measurement subcutaneus adipose tissue layer information and visceral adipose tissue both information.At this, Figure 19 is that expression is configured in the figure that electric current on visceral adipose tissue and the left and right sides aponeurosis (aponeuroses) 15R of portion, the 15L applies the impedance measurement configuration example of the subcutaneus adipose tissue layer under electrode 10f, the 10e, V1 represents visceral adipose tissue measurement potential difference, V2 represents right front sidepiece subcutaneus adipose tissue layer measurement potential difference, and V3 represents left front sidepiece subcutaneus adipose tissue layer measurement potential difference.Can think that the left and right sides organized layer of organism is smoothly symmetrical substantially, therefore

Be configured in addition with electric current and apply the close voltage measurement electrodes all around of electrode, use the electrode of any configuration can both obtain same measurement result.Figure 20 is that expression is configured in the figure that electric current near portion visceral adipose tissue layer and the umbilicus A and the left aponeurosis (aponeuroses) 15L of portion applies the impedance measurement configuration example of the subcutaneus adipose tissue layer under the electrode, V1 represents visceral adipose tissue measurement potential difference, the subcutaneus adipose tissue layer was measured potential difference near V2 represented umbilicus, and V3 represents left front sidepiece subcutaneus adipose tissue layer measurement potential difference.Figure 21 is that expression is configured in the figure that electric current on visceral adipose tissue and right aponeurosis (aponeuroses) 15R of portion and the left aponeurosis (aponeuroses) 15L of portion applies the impedance measurement configuration example of the subcutaneus adipose tissue layer under electrode 10f, the 10e, V1 represents visceral adipose tissue measurement potential difference, V2 represents right abdomen subcutaneus adipose tissue layer measurement potential difference, and V3 represents left front sidepiece subcutaneus adipose tissue layer measurement potential difference.Figure 22 is that expression is configured in the figure that electric current on visceral adipose tissue and a plurality of position applies the impedance measurement configuration example of the subcutaneus adipose tissue layer under the electrode, V1 is by representing visceral adipose tissue measurement potential difference with the combination of I1, V2 is by representing forward right side portion subcutaneus adipose tissue layer measurement potential difference with the combination of I1, V3 measures potential difference by near portion's subcutaneus adipose tissue layer representing umbilicus with the combination of I2, and V4 is by representing left abdomen subcutaneus adipose tissue layer measurement potential difference with the combination of I3.

Figure 24 to Figure 26 represents actual electrode configuration example.Figure 24 is configured in voltage measurement electrodes than umbilicus to enclose the figure of week by top, Figure 25 is configured in voltage measurement electrodes than umbilicus to enclose the figure of week by the bottom, Figure 26 and Figure 24 are same, are voltage measurement electrodes to be configured in than umbilicus enclose week by top but draw the locational figure of aponeurosis (aponeuroses) of 21 positions by the tendon on top a little than the umbilicus A of rectus abdominis m..

＜utilized the mensuration of the interior fat etc. of rectus abdominis m. 〉

The following describes the mensuration of interior fat of having utilized rectus abdominis m. etc.By skeletal muscle (rectus abdominis m.) organized layer is utilized as imaginary electrode layer,, can guarantee measurement sensitivity to visceral adipose tissue to increasing electric current energising amount than skeletal muscle tissue layer interior organs and tissues and visceral adipose tissue in the inner part.The collocation method of the rectus abdominis m. organized layer imagination electrode that Figure 27～Figure 29 represents to use in the present invention.Figure 27 is the figure that the actual configuration of trunk abdominal part is shown from face side and rear side, and Figure 28 is the figure that schematically shows the structure of Figure 27.Figure 29 is the figure that Figure 27 is represented as equivalent circuit.

As shown in figure 27, rectus abdominis m. organized layer 30 correctly is arranged with muscle fiber along trunk length direction rule, when near stem length passes to 50KHz to the highly sensitive frequency current of muscle fiber the time, induction dominant trait earth-current becomes conduction guide in rectus abdominis m. organized layer.Other outer oblique abdominal muscle organized layer 31 mobile obliquely muscle fibers are compared energising property variation with rectus abdominis m. organized layer 30.

Particularly, in the torso length direction, under the chest and between back waist obliquely on the interval of trunk energising, the machine direction of outer oblique abdominal muscle organized layer 20 is with respect to energising direction arranged vertical, become the highest condition of specific insulation, therefore, low as the function of power-on boot.

As shown in figure 28, the structure outside-in of trunk abdominal part is expressed as the bedded structure of the tissue of subcutaneus adipose tissue layer (FS), skeletal muscle tissue layer (MM), visceral adipose tissue (FV) and interior organs and tissues (VM).This is also such as shown in Figure 6.And skeletal muscle tissue layer (MM) is divided into the skeletal muscle tissue layer (MM2) of the trend of muscle fiber obliquely beyond rectus abdominis m. organized layer (MM1) and the rectus abdominis m. organized layer.

ρ?MM1<<ρ(VM+FV)<ρ?FS

ρ?VM<<ρ?FV

ρ?MM1<ρ?MM2

ρ MM2=ρ VM or ρ MM2＜ρ VM

ρ FV=ρ FS or ρ FV＜ρ FS

At this,

The specific insulation of subcutaneus adipose tissue layer: ρ FS

The specific insulation of the complex tissue layer of interior organs and tissues and visceral adipose tissue: ρ (VM+FV)

The specific insulation of the rectus abdominis m. organized layer in the skeletal muscle tissue layer: ρ MM1

The specific insulation of the skeletal muscle tissue layer of the trend of muscle fiber obliquely beyond the rectus abdominis m. organized layer: ρ MM2

Therefore, when replacing with impedance information, above-mentioned formula 31 is expressed as.

Ztm＝V1/I＝ZMM2//(ZVM+ZFV)

At this, Ztm is the resultant impedance of the trunk abdominal part that replenishes in

voltage measurement electrodes

36 and 37, when being made as ZMM two ZMM2, becomes Ztm=ZMM//(ZVM+ZFV), and this is identical with above-mentioned formula 44.Therefore, can measure the visceral adipose tissue amount by above-mentioned method.
