Description

Body fat measuring device

Technical field

The present invention relates to body fat measuring device and upper limb unit, more particularly to internal organ can be measured with impedance method The body fat measuring device and upper limb unit of fat mass.

Background technique

All the time, the measurement of visceral fat mass is by the abdomen according to X ray CT (Computed Tomography) What fault plane was surveyed.For this purpose, visceral fat mass could be measured in the presence of the medical institutions only in the equipment for possessing X ray CT The problem of.Even MRI (Magnetic Resonance Imaging) can also carry out abdomen tomography identical with X ray CT The photography of image, but thick-and-thin is still needs to large scale equipment.Therefore, subject itself can not at home easily Measure visceral fat mass.

Therefore, it as the method for easy measurement visceral fat mass, advocates use impedance method in recent years.

For example, disclosing the body according to subject in Japanese Laid-Open Patent Publication 7-79938 bulletin (hereinafter referred to as patent document 1) The impedances of body specialization information and four limbs calculates visceral fat mass.In special open 2000-152919 bulletin (hereinafter, patent Document 2) in disclose with hand and abdomen conductive contact, provide electric current to hand and abdomen, find out human body impedance, thus measure upper half The body fat rate of body.Thus, it is possible to grasp subcutaneous fat endomorphy type or interior fat endomorphy type.In special open 2002- In No. 369806 bulletins (hereinafter, patent document 3), disclose according to the biological information (waist or gender etc.) of measurement person and The voltage value etc. of abdomen calculates the technology of visceral fat mass.

In addition, proposing keeps subject easy and simplicity in the case where the impedance of abdomen determination of electrode abdomen is arranged Abdomen is attached to the abdomen ground motion of oneself by ground with electrode.

In above patent document 3, subject is disclosed by the way that the band for being provided with multiple electrodes in advance is wrapped in abdomen And electrode is allow to contact abdomen.

In turn, it as the technology of contraposition, is disclosed in special open 2002-282241 bulletin (hereinafter, patent document 4) Use hand keep and become device basis matrix on be provided with for the navel of person to be measured to be aligned as base position Navel position configuration part.As navel position configuration part, it is embedded in and penetrates through from the front of matrix to the hole at the back side and be uprightly arranged Clava.

Patent document 1: Japanese Laid-Open Patent Publication 7-79938 bulletin

Patent document 2: special open 2000-152919 bulletin

Patent document 3: special open 2002-369806 bulletin

Patent document 4: special open 2002-282241 bulletin

However, not disclosing the information by energetically obtaining subcutaneous fat amount in Patent Documents 1 to 3 to calculate Visceral fat mass.Therefore, problem is, not can avoid the influence of the subcutaneous fat of abdomen, can not Accurate Determining.Separately Outside, it does not record in patent document 4 and acquires visceral fat mass this point.

In addition, for the device disclosed in the patent document 4, person to be measured is needed using feeling to set claval navel position It is consistent with the navel of itself to determine portion.

Alternatively, the face of setting display unit 21 is not provided with hinge 33, subject surveys to confirm in the state of measuring posture Determine as a result, its inclination can be made in advance.

Alternatively, display unit 21 and/or input unit 22 can be only fitted to the back side (the opposite face with face 130) of main part 110. In this way, upper limb unit 1 can be made to minimize.

Body fat measuring processing in first embodiment of the invention shown in the flow chart of Fig. 6, it is pre- as program It is first stored in storage unit 27, which is read by arithmetic processing section 26 and executes, to realize the function of body fat measuring processing Energy.

Referring to Fig. 6, arithmetic processing section 26 accepts the input (step of subject's information including build information (waist) S2).The subject's information accepted herein is for example by 27 blotter of storage unit.

Then, arithmetic processing section 26 is standby until the instruction for having measurement to start (in step s 4 for " no ").Work as detection When measuring the instruction of beginning out (being in step s 4 "Yes"), arithmetic processing section 26 sets electrode (step S6).More specifically It says, control terminal switching part 14, using two pairs of electrodes H1, H2, F1, F2 as electric current electrode, connects it with constant current generating unit 12 It connects.In addition, making electrode H1 and electrode H2 short circuit, make electrode F1 and electrode F2 short circuit.In turn, 26 control terminal of arithmetic processing section is cut Portion 14 is changed, using two pairs of electrodes H3, H4, F3, F4 as voltage electrode, connect it with voltage detection department 13.In addition, making electrode H3 and electrode H4 short circuit, make electrode F3 and electrode F4 short circuit.

Then, arithmetic processing section 26 controls constant current generating unit 12, applies from electrode H1 and electrode H2 to electrode F1 and electrode F2 Add constant current (step S8).In this state, arithmetic processing section 26 make voltage detection department 13 detect electrode H3, H4 and electrode F3, Potential difference (step S10) between F4.

Impedance computation portion 261 calculates impedance Z w (step S12) according to the potential difference meter detected in step S10.Herein The value of calculated impedance Z w is for example by 27 blotter of storage unit.

Then, arithmetic processing section 26 switches voltage with electrode (step S14).More specifically, arithmetic processing section 26 is controlled Voltage is switched to electrode B, C from electrode H3, H4, F3, F4 with electrode by terminal switching part 14 processed.As a result, in terminal switching part 14 In, cut off the connection of electrode H3, H4, F3, F4 and voltage detection department 13, connection electrode B, C and voltage detection department 13.

Then, in the state of applying constant current to electrode F1 and electrode F2 from electrode H1 and electrode H2, arithmetic processing section 26 Voltage detection department 13 is set to detect the potential difference (step S16) between electrode B, C.Wherein, when in the shape for flowing into electric current to four limbs When detecting the potential difference of abdominal electrode under state, such as it can apply from one in electrode H1, H2 one into electrode F1, F2 Electric current.

Impedance computation portion 261 calculates impedance Z t (step S17) according to the potential difference detected in step S16.Herein The value of calculated impedance Z t is for example by 27 blotter of storage unit.

Then, 26 switching electric current of arithmetic processing section is with electrode (step S19).More specifically, control terminal switching part 14, electric current is switched into electrode A, D from electrode H1, H2, F1, F2 with electrode.As a result, in terminal switching part 14, electrode is cut off The connection of H1, H2, F1, F2 and constant current generating unit 12, connection electrode A and electrode D and constant current generating unit 12.

Then, arithmetic processing section 26 controls constant current generating unit 12, to application electric current (step between electrode A and electrode D S20).In this state, arithmetic processing section 26 makes voltage detection department 13 detect the potential difference (step between electrode B and electrode C S22).Impedance computation portion 261 calculates impedance Z s (step S24) according to the potential difference meter detected in step S22.It calculates herein The value of impedance Z s out is for example by 27 blotter of storage unit.

Then, visceral fat mass calculation part 262A according to inputted in step S2 build information (waist), impedance Z t, Visceral fat area Sv (step S26) is calculated with impedance Z s.Visceral fat area Sv is calculated by above-mentioned formula (1).
