Description

The invention relates to a measuring device for bioelectrical impedance analysis (BIA) of the body of a person, wherein a plurality of alternating current leading electrode pairs (here: input electrodes) and several voltage drop measuring sensitive electrode pairs (here: output electrodes) brought into contact with the surface of the body and the bioelectrical impedance of the body segments is metrologically recorded between these output electrodes and the obtained measured values are converted with stored, for example statistical, data into a body structure and visceral risk analysis.

During the measurement, an alternating current in the kHz range generated in a measuring device via the input electrodes in the body of the person generates an electromagnetic field which propagates three-dimensionally between the input electrodes in all tissue layers and is measured with the output electrodes. In order to capture a body region that is as meaningful as possible during the measurement, the electrodes are placed in characteristic prominent areas of the body and connected to a measuring device in such a way that optimal reproducibility is achieved in repetition measurements.

To determine a size related to whole body fat content, for example, a hand-foot measurement of the body's internal impedance is possible with as few as four electrodes. In this case, the person is in each case an input electrode on the right foot and the right hand and in the vicinity of each attached an output electrode, so that an electromagnetic field between the pulse-giving electrodes of the right hand and the right foot is established during the measurement. The measured potential difference between the output electrodes and the strength of the continuous current and the phase shift then represent a measure of the impedance of the body.

In the DE 602 05 976 T2 For the evaluation or estimation of the visceral body fat ratio, a measuring instrument with eight electrodes is described which can be used to measure not only a hand-hand and foot-foot measurement of the bioelectrical impedance, but also the body weight as well as the person's blood pressure and pulse rate. For this purpose, the measuring device is designed in the form of an L-shaped scale, on the foot part of which four foot electrodes and on the lateral handles of which two hand electrodes are respectively arranged. For measurement, the person stands on the foot part so that one toe of the right and one left foot makes contact with the input electrode and the heel of the right and left foot makes contact with the output electrode. At the same time both side handles are touched with the hands, whereby the contact with the there arranged input and output hand electrodes is made.

In order to calculate the proportion of different body fat tissue by determining the bioelectrical impedance of a body, in the DE 11 2008 001 501 T5 a foot-foot and hand-hand, combined with a belly measurement with a total of twelve electrodes proposed. To measure the person in lying position with a fastening unit in the form of a belt four electrodes - two input and two output electrodes on the stomach and by means of cuffs one input and output electrode on the upper limbs, here at the wrists and one input and output electrode attached to the lower limbs, here at the ankles. The abdominal measuring section, which consists of 4 electrodes, measures a total resistance over this measuring section, whereby no partial resistances can be measured for the different fat tissues and therefore a differentiation between subcutaneous and internal fatty tissues is not possible. Likewise, there is no contacting of the abdominal electrodes in combination with the hand and foot electrodes, whereby targeted measuring sections of the upper trunk and the lower abdominal area are not possible.

A disadvantage of known methods for measuring the bioelectrical impedance of a body is the often considerable effort of the wiring, in particular when involving a stomach measurement, namely that a person can not perform such a measurement independently or at the same time only with great difficulty. Also, the necessary placement in the lying position means a procedural overhead compared to a measurement in a standing position.

With the German patent application 10 2013 106 690.9 as well as the European Patent Application 14 749 708.5 , which on 6.02.2019 as EP3048967 has been registered, a method is described, wherein a measurement can be performed autonomously by a person and the measuring sections in each case differentiated include the stomach, the upper body and the arms with. With the German patent application 10 2013 022 145 A1 (2015.04.23), which was initially used as a supplementary supplementary application German patent application 10 2013 106 690.9 was registered, the legs are included in this measurement process.

Starting from the described prior art, it is an object of the invention to provide a measuring device, with the one person in a simple way in a measuring several transversal BIA abdominal measurements with the other longitudinal BIA-abdominal-hand, BIA-hand-hand, BIA-hand-foot, BIA-abdominal-foot and BIA-foot-foot measurements can be performed independently.

The object is achieved procedurally with the characterizing features of claim 1 and device with the characterizing features of claim 5, characterized in that by means of a band-shaped measuring template, which is connected to a measuring module and the left and right in the two middle stencil sections by multiplexer switchable having an input and an output electrode and is additionally positioned with a pair of electrodes on the left template side between the input and output electrode and on the handles of the outer template sections each left and right an input electrode and an output electrode, from the person self-sufficient in a simple At the same time two BIA-belly, one BIA-belly-hand, one BIA-hand-hand, one BIA-hand-foot, one BIA-belly-foot and one BIA-foot-foot are performed, to which the measuring template of the person on the handles - with thumbs-pointing Finger contact in the memory handle on the local electrodes - held horizontally and their middle and outer template sections with the electrodes arranged there by means of an orientation aid on the navel centered and in a standing posture in a relaxed arm position and so reproducible measurement position on the stomach are created. The measuring person stands with both feet on a scale-like measuring surface with two pairs of recessed electrodes, each having an input and output electrode per foot, which differs from the customary fat scales by a mark for the reproducible setting up of the heels and thus that a broader sting is taken with further foot distance and skin contacts of the inner thigh insides are avoided as an abbreviation of the organic conductor configuration.

To produce the defined measuring position, the abdominal measuring template is shaped in such a way that the measurement can be carried out reproducibly, because the arm posture is based on the natural movement and posture behavior. This holding the measuring module to the abdomen requires no additional instructions, as it must be done in contrast to other equipment, such as an exactly to be followed arm posture, which is determined by the distance of the person to the hand contacts of a meter, already a change in the measuring sections conditionally. The memory grip between thumb and forefinger electrodes leads to a unique trace as opposed to ladder configurations with contacts on the palms of the hands, which experience changes as the wrists are adjusted differently.

The more accurately a given conductor configuration can be repeatably taken in subsequent measurements, the more accurate the evaluation of the trace composition can be, because a change in the limb attitude already causes a shape and thus a change in volume, which directly has a change in the conductivity components result.

So that the measurement can be carried out by all persons with small to large abdominal circumferences, according to an advantageous embodiment of the invention, the outer template sections of the measuring template are so flexible that they can be adapted to the abdominal circumference of the person during the measuring process. The center of the template is marked with a marking, for example a recess or a prominent elevation, a "knubbel". For measurement, this marking is applied to the belly button and the abdominal electrodes arranged on the underside of the measuring template are held horizontally against the abdomen. This ensures that the abdominal electrodes are located at the same position laterally from the navel at each measurement.

The abdominal electrodes are arranged symmetrically around the marking (belly button) such that the output electrodes are located, for example, in the waistline to the left and right 7 cm and farther outward the input electrodes are, for example, 11 cm away from the mark on the left and right.

This existing wide configuration is additionally equipped in the new invention with a narrow electrode pair, which is arranged symmetrically between input and output electrode of a template side, so that the electrodes are removed, for example, each 1cm from these electrodes. This short measuring section measures with a low penetration depth and is considered to be sensitive to the subcutaneous fat layer thickness. The further the electrode position, the deeper it is measured into the abdomen, whereby the resistances of the visceral fats are detected.

The measurements made with the aid of the measurement template are used to generate a visceral risk analysis. In summary, the wide abdominal measurement section gives the layer thickness of the subcutaneous fatty tissue and moreover a statement about further internal abdominal compartments, such as the visceral fat. The new invention with integration of the separated subcutaneous fat layer measurement by, for example, 2 cm close electrode position differentiates the previously statistical statement on the proportions of the skin fat and visceral fat impedances, by measuring the subcutaneous fat resistance separately, which can then be differentiated from the total resistance of the example 14 cm wide abdominal measuring distance and thus allows a specific statement about the visceral fat content.

Advantageously, the otherwise complicated measuring units and cabling for the electrodes that are otherwise required in known measuring devices for the measurement are not required.

The paired foot electrodes are symmetrical to each other for the right and left foot, with each footpad electrode surface acting as a signal input electrode and the heel electrodes measuring the voltage drop by being connected to a BIA measurement module by conduction, regardless of whether the measuring electronics in this foot element, as typically integrated in a person-foot scales or in the abdominal template is. This allows BIA hand-foot, BIA-belly-foot and BIA-foot-foot measurements.

The measured values generated at a measuring frequency of, for example, 50 kHz AC pulses are detected by the measuring module and can be used with a connected computer unit or calculation unit for producing a structural and visceral risk analysis. The measuring module, which contains a current pulse generator for the input electrodes and a voltage drop meter for the output electrodes to carry out the measurement, is inventively integrated as a fixed component in the abdominal measuring template or in the scale-like foot element as a measuring platform. Alternatively, the measuring module is designed as a separate device and connected to the measuring template and / or foot element via a corresponding device.

For example, the measuring module is inserted into a contact pin strip arranged on the upper side of the measuring template, into which the connecting lines of the electrodes open, or the measuring module is connected to the measuring template via a common line containing the electrode connecting lines or the measuring module integrated in the template or in the base element sends the measured data via radio or Bluetooth to an external evaluation unit.

The multiple BIA-abdominal, BIA-abdominal-hand, BIA-hand-hand, BIA-hand-foot, BIA-abdominal-foot and BIA-foot-foot are not pure fat measurements, but serve body structure analysis, especially in relation to the Water content and the muscle-fat relation. By combining the two BIA abdomens with the BIA-abdominal hand, BIA-hand-hand, BIA-hand-foot, BIA-abdominal-foot and BIA-foot-foot can be in terms of a visceral risk analysis previously existing uncertainties to a large extent and extend as segmental analyzes of the limbs and trunk, the subcutaneous and visceral abdominal fat tissues, as well as the overall body structure analysis.

The method of the present invention uses seven input current-emitting electrodes (both thumbs, both outer plus a multiplexer-switchable and thus dual-functional inner tibial electrode, both heel electrodes) of the gauging template and the foot member, which can be combined into twenty-one possible pair connections.

On the measuring template and the foot element there are eight output electrodes (both index / middle fingers, both inner abdominal electrodes of the wide abdominal measuring section, both inner abdominal electrodes of the narrow subcutaneous fat measuring section, both foot ball electrodes), which can be combined into twenty-eight possible pair connections. In total, 588 measuring distances are possible, which can theoretically be measured consecutively. Real, however, only a few of these measuring sections are necessary for a meaningful calculation.

Further details and advantages of the invention will be explained in more detail with reference to embodiments illustrated in schematic drawing figures.

In the 1 is shown in a front view of the upper body of a person.

In both hands there is an input electrode in the area of the index finger 12 and in the region of the thumb, an output electrode 12 ' , Continue to be on the right and left of the belly button 21 one output electrode each 14 and next to it, offset to the right and left of the belly button 21 one input electrode each 13 , A double function is taken over by the abdominal electrode 14 / 13 as a multiplexer switchable input and output electrode. Thus, the arrangement of the 6 abdominal electrodes makes it possible to measure a long measuring distance with the outer input 13 and the output electrodes 14 , as well as a short measuring distance between the inner ( 13 / 14 ) and outer input electrode 13 and the output electrodes 14 ' ,

Which, with a corresponding activation between them by electrode connection lines ( 19 . 2 ) with an intermediate AC pulse generator ( 17 . 2 - 5 ) connected input electrodes 12 and 13 resulting field lines 20 ' , or the generated electromagnetic fields 20 ( 1 ) are marked accordingly in the upper body of the person. These electromagnetic fields are measured 20 or their attenuation through the via electrode connection lines ( 19 . 2 ) with an intermediate voltage drop meter ( 18 . 2 - 5 ) interconnected output electrodes 12 ' and 14 ,

As the schematic representation of 1 can be clearly seen, can be generated by four input electrodes almost in the entire upper body and abdomen together with the person's arms a metrologically relevant field. By selective combination of individual pairs of electrodes can be very specific individual measuring ranges 23 metrologically capture the body, as in the following drawing figures 2 to 5 is shown schematically by way of example.

In the 2 is a dark highlighted measuring range extending over the right arm 23 drawn, which is to be detected by measurement. To realize the measurement, the input electrodes 12 the left and right forefingers activated and the output electrodes 12 ' of the right thumb and right output electrode 14 The abdominal electrodes measure the voltage drop and the phase shift of this field.

In the 3 comes with identical input electrodes 12 the two index fingers of the 2 made a change in the output electrodes. The output electrode 12 ' of the left and right thumb determine the one in the 3 dark highlighted measuring range 23 the shoulder, the upper rib cage and the two arms (BIA hand-hand). The abdominal electrodes 13 . 14 were not included in the measurement in this example.

In the 4 is the longer of the two measurement sections on the lower abdomen (BIA abdomen) corresponding to the dark highlighted measurement range 23 shown.

For this purpose, only the abdominal electrodes 13 . 14 used in this measurement, with the two outer input electrodes 13 Generate the field and measure the two inner output electrodes, the voltage drop and the phase shift. In this example, therefore, the hand or finger electrodes are not included in the measurement.

A measurement of the left upper body and trunk (BIA-belly-hand), in the 5 as dark highlighted measuring range 23 is possible with the following electrode combination: The input electrodes are 12 of the left index finger and 13 of the right abdominal electrode. Output electrodes are 12 'of the right thumb and the left of the abdominal electrodes 14 , However, slightly modulated but adequate ranges of measurement could be the combinations of the input electrodes 12 of the left index finger and 13 of the left abdominal electrode with the potential difference measuring output electrodes 12 ' of the right thumb and one of the inner abdominal electrodes 14 such as 14 ' ( 1 . 6 ) produce.

In particular, the electrode combinations of 4 and 5 , in which abdominal electrodes and hand electrodes are used simultaneously, can be carried out in a simple manner with a measuring template according to the invention and complement each other in the quality of the statement about the medically relevant "visceral risk".

In the 6 is a schematic perspective view of the structure of such a measuring template 2 shown as a sketch. The band-shaped measuring template 2 consists of a band-shaped molded body 3 on his top 4 in the area of its outer template sections 15 . 16 left and right with handles 8th . 9 is provided. With these handles 8th . 9 can the measurement template 2 held by their band-shaped form only with a differentiated memory grip with the thumbs from above under primary use of the index finger from below in a predetermined by this grip position physiological arm posture and created on his own stomach. To support a reproducible measurement, this arm posture is one of the essential prerequisites in terms of an as identical conductor configuration as possible. as well as the optimal contacting of the electrode surfaces with the abdominal surface, through the flexible template sections 6 . 7 . 15 . 16 is achieved, so that they are holding the measuring template 2 can adapt to the transversal waist circumference.

In each of the handles 8th . 9 there is an input electrode 12 and an output electrode 12 ' , They are arranged one behind the other so that they are held while the measuring template is being held 2 inevitably come through the thumb-index finger memory handle in contact (in the drawing figure 6 is only the output electrode 12 ' visible). On the bottom 5 the band-shaped measuring template 2 are located 6 Electrodes arranged. These electrodes define a short measuring distance here, for example, over the left side of the template in the area 6 the template is positioned with the input electrodes 14 / 13 and 13 as well as the narrower output electrodes placed therebetween 14 ' and one over both sides 6 and 7 the stencil extending long measuring distance with the outer input electrodes 13 and the inner output electrodes 14 and 14 / 13 , The electrode 14 / 13 has a dual function as input and output electrode and is switched over for the measurement of both lines each by multiplexer and thus used differentiated. The output electrodes 14 and 14 / 13 are left and right, for example, 7 cm and the input electrodes 13 left and right, for example, 11 cm from the one with a marker 11 provided template center away. The input and output electrodes of both measuring sections are arranged in pairs in a congruent manner, so that the output electrodes 14 ' the short measuring distance have a distance of for example 2 cm from each other.

The marks 11 . 11 ' and 11 " the center of the template serve as an aid to place the center of the template on the belly button before the measurement ( 21 . 1 ) to be able to position.

As in 6 ' Depending on the design, this marking can be displayed from an omission 11 or a hole 11 ' in the template or even from a prominent element, such as a rounded cone 11 " consist. The exact positioning on the belly button and the resulting predetermined levels of transverse and longitudinal alignment of the template are essential for the repeat accuracy of all participating measuring sections of the abdominal electrodes 13 . 14 . 13 / 14 and 14 'with each other and in combination with all other electrodes 12 . 12 ' the hand and 29 . 30 the foot elements 27 ( 7 . 8th , 8 ', 8 ").

In the illustrated embodiment, no electrode connection lines are shown, since these are integrated in the measuring template and in one at the top 4 the measuring template 2 arranged contact pin strip 10 lead. The current pulse generators, voltage drop meters and multiplexers required for the measurement are likewise not shown, since they are components of the measuring module 1 with display and control buttons 1' which are in the contact pin header 10 is designed to be inserted.

In the 7 is shown in a front view of the lower torso and the legs of a person standing on a foot-measuring element. Under both feet is located in the area of the heel an output electrode 30 and in the field of football an input electrode 29 ,

The corresponding with an activation between the interconnected by electrode connecting lines with an intermediate current pulse generator input electrodes 12 . 13 and 29 resulting field lines 20 ' , or the generated electromagnetic fields 20 are corresponding to those in upper body and arms ( 1 ) in the lower torso and the legs of the person.

These electromagnetic fields are measured 20 or their attenuation induced by the body tissues, with the electrode connection leads 19 between the input electrodes 12 (eg 19 . 2 ) and with a voltage drop meter (eg 18 . 2 - 5 ) via the interconnected output electrodes 12 ' . 14 and 30 (eg 7 ) is interposed. As the schematic representations in 1 and 7 can be clearly seen, can be generated approximately in the entire body, the trunk and abdomen together with the arms and legs of the person a metrologically relevant field. On the drawing of the field lines 20 ' and fields 20 through the entire body as when activating the input electrodes 12 and 29 was omitted for reasons of clarity. By selective combination of individual pairs of electrodes can be very specific individual measuring ranges 23 metrologically capture the body, as in the drawing figures 2 to 5 is shown schematically by way of example.

In 8th . 8th' , 8 "are in different oversight foot measuring elements 26 shown. The element in 8th corresponds in shape and size of a "normal" bathroom scale. A weighing function can be an element of this foot measuring element. For all foot gauges, there is an output electrode in the heel area for both feet 30 and in the area of the forefoot and football an input electrode 29 located. For the correct placement of the feet are two schematic illustrations of different foot sizes 28 and 28 ' applied. One arrow each and one boundary line 31 , which may also be formed as a noticeable bump, should represent the marking for the heel. Furthermore, this foot-measuring element 26 with a display 32 to display the measured values and optionally the weight, as well as according to need and equipment the results of the analyzes show. In this foot can optionally also the measuring device 1 to get integrated. The connection socket 33 . 33 ' provides the possibility of the foot-measuring element 26 with the measuring module 1 or, depending on the design, optionally with the abdominal measuring template 2 by means of electrode lines 34 connect to.

Optionally, these electrode connection leads can also be integrated into a stand, wherein the stand also serves as a carrier and holding and loading device for the abdominal template 2 and the measurement module 1 can serve. An embodiment in the form that a display, for example a tablet computer on this stand controls the menu-guided measurement by means of an integrated computer unit and optionally also this display module controls the BIA measuring device 1 contains is also provided.

The focus is always on the simple operability of the ideally self-executable by Laity measurement process.

Optionally, for example, in bedridden persons this foot measuring element 26 find application in supine position where the element is employed at right angles to the bed surface and the person positions the feet according to the markings or leaned against the lower bed wall or integrated in the hospital bed in the foot-side inner wall.

The wide and split shape of the foot element 8th' and 8th "meet the requirement from practice that increasingly obese people the required isolated measuring position of the two thighs from each other on a normal scale platform 7 . 8th can not comply with, which can result in incorrect measurements by shortened measuring distances. Depending on the design, the wide and divided foot elements 27 ' . 27 " be equipped with a weighing function or space-saving can be arranged in the same form training detachable on a scale platform to place them independently if necessary for the measurement process, for example, next to the scale.

On the in 9a and 9b The schematic abdominal transverse sections at belly button height shown are the metrologically relevant tissues and organs as shown in the magnetic resonance imaging (MRI) and the two transversal abdominal measurement areas 20 . 20 ' drawn on the front of the abdomen. Essential for the differentiability of different fatty tissue in the form of subcutaneous fat 38 and visceral fat 39 is the selection of the measuring section length, so that the long measuring distance ( 9a) between the input electrodes 13 and the output electrodes 14 . 14 / 13 the electric field 20 penetrates into the deeper abdominal regions and the short measuring distance ( 9b) between the input electrodes 13 . 14 / 13 and the output electrodes 14 ' the depth of penetration is limited and thus sensitive to the subcutaneous fatty tissue. The sum of the impedance which is induced by the long measuring section also in deeper body regions impulses must be reduced by the resistances of the Unterhautfettgewebes, in order to achieve an independent statement quality over the Viszeralfett.

In 10 a person in the exemplary stationary measurement position with "natural" ie physiological attitude of the limbs is shown wherein all tracks in the form of the limbs and the trunk are measured as measuring sections in the entire length and measurement errors are avoided as by the torso applied limbs 40 by the foot electrode assembly 29 . 30 over a wide foot platform 26 be contacted and the angled arm posture 40 by the arrangement of the handles 8th . 9 done an attitude of abdominal measurement template 2 with a memory handle.
