Definitions
- the medicine has measuring methods with which the instantaneous nutrition and fitness condition of humans can be determined.
- Blood analyzes provide information on whether sufficient nutrients have been supplied to the body.
- V02max the endurance performance of humans can be objectively determined. This information could be the basis for people to change their behavior in terms of diet and exercise, thereby providing preventative health benefits.
- pulse measurement and pedometer allow to measure the extent of physical activity and to improve physical fitness through targeted training.
- both methods assume that a person has already decided to change their behavior, because the biofeedback works only in connection with physical activity. Both methods are therefore not sufficient to initiate behavioral changes. A determination of the nutritional status is thus not possible anyway.
- the above object is realized by an analysis apparatus according to claim 1 and by a method according to claim 9.
- Preferred embodiments of the apparatus and method are subject of the dependent claims.
- the present application proposes a measuring device and a method for determining the nutritional status, the physical endurance performance (V02max) and the lifestyle related stress to solve the said problems.
- MSS miniaturized spectroscopic system
- RS reflection spectroscopy
- RRS resonance Raman spectroscopy
- Free radicals are permanently produced in human skin as a result of metabolic processes, solar radiation and the influence of environmental pollution and toxins. Normally, these redox processes are well balanced by the antioxidant defense system, but in the case of an obvious increase in free radical concentration, oxidative reactions dominate, leading to oxidative stress conditions.
- Free radical-induced oxidative stress is the main reason for the development of premature skin aging and other skin diseases including skin cancer.
- a protective effect of antioxidants has also been found in reducing the risk of cardiovascular disease.
- the various cutaneous antioxidants include, carotenoids (alpha-carotene, beta-carotene, lycopene, lutein), vitamins (A, C, D, E), enzymes (superoxide dismutase, catalase, glutathione peroxidase) and other substances (flavonoids, lipoic acid , Uric acid, selenium, coenzyme Q10, etc.).
- RRS resonance Raman spectroscopy
- Buckley et al. mentions in 1964 the possibility of carotenoids in human skin by reflection spectroscopy at an excitation of about 480 nm to determine [1]. The influence of other cutaneous chromophores did not make the measurement of carotenoids reproducible.
- a measuring arrangement for the detection of carotenoids is shown in US2009 / 0306521, the aim of which is to reduce the influence of hemoglobin (Hb) on the carotenoid measurement by pressing the Hb out of the tissue by appropriate pressure.
- the measuring arrangement has a bulge, which is deliberately pressed into the tissue during the measuring process.
- the system does not have a light barrier, so even light directly reflected from the surface gets into the spectrometer without having taken the path through the tissue.
- a disadvantage of this arrangement is that the pressure over a certain period of time must be maintained and that when reducing the pressure again hemoglobin can flow back into the tissue. The boundary conditions influencing the measurement result may therefore vary during the measurement.
- the aim of this application is to provide constructive measures to ensure that the absorption conditions of the skin are not changed by the placement of the measuring system and the influence of Hb by the distance (light barrier) between the location of the radiation and the place the detection of the remission light is reduced. Over the distance, it can be ensured that light from tissue depths without blood vessels (epidermis) is analyzed so that the influence of Hb is minimized.
- the light barrier ensures that no light reflected only by the surface is analyzed, but only light that has previously passed through the skin. When measuring is about the size
- the support surface ensures that the absorption conditions of the skin remain unaffected even under increased pressure because the force per unit area falls below a spectroscopically relevant size.

- Figure 8 shows a prediction of VO 2 max values by spectroscopic
- Figure 9 shows the process of determining nutritional status
- a schematic representation of the mobile device is shown in Figure 1.
- a possible optical resolution of the spectrometer is 3 ⁇ 1 nm.
- the most important component is the light barrier (6) between the windows (coupling (4) and coupling (5)), which forces the light Penetrate into the skin and prevent measurements where the light is only reflected from the surface of the skin.
- the light barrier is opaque and represents the distance between the coupling-out window and the coupling window.
- the mobile device uses the tissue underneath its contact surface as a diffusely reflecting substrate.
- the area of the mobile device in contact with the skin surface should therefore be of sufficient diameter to ensure a homogeneous distribution of contact pressure on the skin surface.
- the LED illuminated skin surface corresponds to the dimensions of the decoupling window.
- the MSS is designed so that the light is used from a depth of up to 200 ⁇ for the detection of carotenoids.
- Figure 2 shows a reference spectrum and a typical reflection spectrum of the human skin measured on the palm of the hand.
- an opal acrylic glass sample was used.
- FIG 3 shows the negative Iog10 of the diffuse reflection of human skin in vivo.
- the spectrum is normalized with the reference spectrum.
- the small dent in the diffusely reflected spectrum in the range between 458 nm and 472 nm (see Figure 3) results from the absorption of carotenoids in the skin.
- the cross validation is done with the random segment method. Four major components were used to predict with the regression vector the RRS values that correlate with the concentration of carotenoids in human or animal skin.
- the RRS measurements were validated with HPLC reference data from biopsies of human and animal skin.
- Figures 4 show calibration curves in vivo from the palm of human skin (4a) and in vitro from uterine skin (4b) based on RRS.
- a correlation coefficient of R 0.85 was achieved.
- the results for RS are displayed on an arbitrary scale.
- human skin as a single numerical value in the range of 1 to 12 and for the uterine skin in the range of 1 to 20. The values can be converted into nmol / g of skin.
- the RRS and RS measurements were made on the same skin area and the RRS measurement was then used as reference values.
- Calibration measurements for human skin were made in vivo on both palms of healthy subjects and for bovine skin in vitro on excised healthy uterine skin. The stability of the measurements was determined by the standard deviation of the measured values not more than 10%. Typically, different series of consecutive measurements on the skin of a subject will yield a standard deviation of less than 5%.
- Figure 5 shows the optical density of a subject's palm over a wider range of wavelengths when illuminated with a white light source (SL1, Stellar.net) and using the Hamamatsu C10988MA spectrometer.
- the light was irradiated onto the skin via a 300 ⁇ m fiber with a stainless steel sleeve and the diffuse reflected light was imaged with a lens onto the slot of the spectrometer.
- the emitted light was collected over a distance of 1 mm.
- the spectra show the absorption bands of oxygenated and deoxygenated hemoglobin at around 415/420 nm, 542 and 577nm / 555nm.
- the measurement range is located between the Soret band and the two absorption bands above 500 nm.
- the two spectra which come from closely spaced positions, show the influence of the scattering properties of the skin.
- human skin is a complex, inhomogeneous, multi-layered, strongly scattering and absorbing medium with a high anisotropy factor.
- the reduced scattering coefficient p s is higher than the absorption coefficient ⁇ 3 obtained by in vitro and in vivo measurements by various methods.
- the randomly inhomogeneously distributed chromophores influence the optical properties ⁇ ⁇ and ⁇ ⁇ of the skin layers. Therefore, the reflection spectra are determined by the scattering properties of the skin and also by the chromophores in the skin. Strong absorbers reduce the backscattered light by absorption into the respective wavelength range where the bands lie. For example, blue light at 465 ⁇ 25 nm penetrates only about 150-200 pm deep the skin (mean path length associated with the high absorption coefficient of the present wavelengths).
- the human skin contains various chromophores that are able to absorb light in the blue region of the optical spectrum and that could potentially affect the reflectance measurements.
- the most common are the carotenoids, melanin, flavin adenine dinucleotide (FAD), reduced FAD (FADH 2 ), deoxygenated hemoglobin or oxygenated hemoglobin, bilirubin, and water.
- the epidermis contains no blood vessels, so hemoglobin and bilirubin can be found for the first time in the basal membrane, which is a border between the epidermis and the dermis. Their concentration increases deep in the dermis with increasing blood content.
- the thickness of the epidermis varies depending on the skin area between 50 ⁇ and 600 ⁇ .
- blood chromophores such as hemoglobin and bilirubin
- the reflectance measurements were therefore performed on the palm of the hand where the epidermis has the greatest thickness (up to 600 ⁇ ).
- the high ⁇ 3 of hemoglobin as well as the scattering properties influence the diffuse reflection, as shown in Figure 5.
- the distance between the coupling window and the coupling window was chosen so that on average only backscattered light from up to 200 ⁇ is obtained.
- the depth distribution of carotenoids in the human epidermis is inhomogeneous with a strong concentration gradient from the skin surface to the deeper layers of the epidermis.
- the highest concentration was found on the skin surface and in the upper layers of the stratum corneum. This can be explained by the continuous secretion of carotenoids via sweat glands and / or sebaceous glands to the skin surface.
- the ratio between the highest carotenoid concentration, measured at a depth of 6 ⁇ 2 ⁇ and the concentration at a depth of 24 ⁇ was found to be about 7 ⁇ 2.
- the carotenoid concentration in the deepest epidermis, the stratum basale is high, which may be related to the diffusion processes of Carotenoids from blood, lymph and adipose tissue. Consequently, the epidermal carotenoids are ideal components for detection with the mobile device.
- the redox cofactors, FAD and FADH2 which play an important role in cellular metabolism, can be found in the highest concentrations in living cells, i. in the deep layers of the epidermis (stratum spinosum and stratum basale). However, these cell layers are not significantly affected by the measurement with the mobile device.
- epidermal chromophores such as the protein-bound amino acids tryptophan and tyrosine as well as nicotinamide adenine dinucleotide (NAD +) reduced NAD + (NADH), urocaninic acid, fatty acids, DNA, vitamin E and proteins, absorb predominantly in the UVB portion of the optical spectrum and therefore have no effect on the performed measurements.
- NAD + nicotinamide adenine dinucleotide
- NADH nicotinamide adenine dinucleotide
- urocaninic acid urocaninic acid
- fatty acids DNA, vitamin E and proteins
- Water has a minimum absorption coefficient in the blue region of the spectrum and thus has no influence on the measurements carried out.
- the mobile device is therefore ideal to measure fast, safe and reliable carotenoids on the palm of the human or the uterine skin and thus to make statements about the antioxidant potential. It can thus be used as a biofeedback system for in vivo monitoring, helping the user to improve their health behavior. Measuring stress
- the stress resulting from the individual lifestyle can be determined. Since the concentration of antioxidants in the skin change rapidly under particular conditions, e.g. By drinking alcohol, little sleep, etc., the resulting stress can be individually calculated for good health. By daily measurements over a longer period, e.g. 14 days, the data represent a more or less typical behavior of the person, which leads to the respective carotenoid concentrations. This means that the mean value of the measured concentration reflects the individual behavior in relation to health care. By comparing the mean with a current carotenoid reading, expressed as a percentage of change, the current behavior can be assessed, with the mean and current reading being able to be enhanced by additional values, particularly measurements from the detection of other vital parameters (e.g., weight).
- other vital parameters e.g., weight
- a positive number means that a person at an individual level advances their health care, while a negative number demonstrates the opposite.
- the number promotes the attitude of the individual with regard to the behavioral changes in the lifestyle necessary for health care. It also allows people to compare their behavior, even if they have different levels of antioxidants.
- carotenoid measurements on the cow udder a screening for the separation of milk from diseased animals can be performed. Due to the fact that the carotenoid concentration in the skin falls in the case of a disease, the relevant milk can be automatically collected via a bypass in a separate vessel if the result is appropriate. Contamination of milk from healthy cows is avoided. A subsequent medical examination decides whether a disease is present or not and whether the quality of the milk still complies with the legal provisions. The advantage of this application is above all economical with regard to the health of the animal and avoidance a contamination of healthy milk. When integrating the MSS into the milking system, the carotenoid measurement can be carried out automatically. When implemented as a mobile handheld system, several animals can be measured with the same device.
- the physical endurance capacity of the human can be determined spectroscopically. In WO 2007/085435 this is done via the measurement of cytochrome C oxidase.
- the enzyme cytochrome c oxidase is located at the end of the respiratory chain (mitochondria) and is responsible for the reduction of oxygen to water. The released energy is used by the muscles. Similar to the detection of antioxidants, the measurement can be carried out by reflection spectroscopy with excitation in the wavelength range of 500nm to 900nm. Since diet and physical fitness have a lasting effect on human health, it is of great benefit if biofeedback data can be made available to the individual using the same spectroscopic system.
- a mobile device with which the concentration of carotenoids and cytochrome C oxidase can be determined must be specially designed, since the spectroscopic measurement takes place in different wavelength ranges. Because short-wave and long-wave and light penetrate different depths into the skin, the width of the light barrier (6) and the window size for irradiation (4) and for detecting the remitted light (5) must take this difference into account.
- Fig. 6 shows a corresponding arrangement in which, for example, the width of the light barrier about 0.5 mm and the size of window (4) about 3x3 mm and of window (5) 3x2 mm.
- the necessary LEDs can be arranged in one or more rows on the illumination unit (8).
- the LEDs required to detect the carotenoids should be closest to the light block (6). Their spacing can be e.g. about 1 mm.
- the reference values for the calibration were determined by spiroergometric tests.
- the correlation coefficient for the detection of carotenoids ( Figures 4a and 4b) was based on the same design of windows and light barrier.
- Figure 6 shows the possible structure of the mobile device consisting of a spectrometer (1), an optical unit (2) and an electronic unit (11) for the control and processing as well as for the transmission of data to a central server on which e.g. the calculation of the substance concentrations takes place.
- the miniaturized spectrometer has e.g. a replicated holographic grating covering a large wavelength range e.g. 390nm - 970nm is designed.
- the optical unit (2) is a monolithic device containing an imaging optical element (7) (eg mirror or lens) for directing the light from the sample to the entrance slit of the connected spectrometer unit (1)
- Recording for a lighting unit (8) is used, which consists of one or more light sources (eg LED) for illuminating a sample (10), such as human skin.
- a light source eg LED
- the use of only one LED with an emission spectrum of 440 nm to 490 nm as a light source is useful for measuring the carotenoids.
- the optical unit (2) has two windows (4,5) of translucent material and a contact surface (9) for placing the mobile device on the sample for measurement (eg, skin).
- Windows (4) allows the illumination of the sample (eg tissue);
- Window (5) allows light to pass from the sample to the imaging optical element.
- a clamping device which compensates for thermal influences.
- the housing of the mobile device (3) protects the optical unit (2) in such a way that by placing the device on the sample no impermissible external forces on the monolithic device and the connected spectrometer (1) act.
- the construction also prevents the influence of other external sources (e.g., light, dust, moisture)
- the illumination unit may preferably consist of a carrier with high heat capacity or e.g. be implemented as a copper plate or as a copper-containing carrier for bonding Nacktchip LED.
- the lighting unit is connected to the electronic unit (11) for controlling and regulating the light source. It is placed in the optical unit and fixed. If several LEDs with the same emission spectrum are used as the light source, which are located at different distances from the light barrier and are switched on one after the other, the light scattered back out of the skin contains location information which enables a more precise concentration determination.
- the optical unit can preferably be produced by injection molding.
- the window (4, 5) the insertion of a separate glass or plastic plate or a two-component injection molding is possible.
- the optical quality of the windows is adapted accordingly.
- the contact surface (9) and windows (4, 5) are at the same level.
- the contact surface (9) Similar as shown in Fig.7, on the contact surface (9) different levels can be realized, for. B. to reduce the sweating of the skin during a measurement or to achieve certain design effects.
- the size of the contact surface is selected accordingly. A size of 16cm 2 and a diameter of about 45mm with a round geometry is a possible reasonable size.
- a spectroscopic reference for calibration may be housed in a removable cap enclosing contact area (9) and windows (4, 5).
- a measurement with cap is made at a selected time and the result is integrated into the calibration algorithm of the mobile device.
- the cap simultaneously protects the windows (e.g., against scratches) when the user places the mobile device e.g. transported in a handbag or backpack.
- the spectroscopic system of the mobile device can also be realized by using a diode array which replaces the spectrometer unit (1). If multiple LEDs are used, each emitting a small and spectrally different wavelength range, the lighting is controlled by the electronic unit (11) so that the LEDs are turned on in succession, so that only light with a small spectral range on the imaging optical element (3) reaches the diode array. Alternatively, it is also possible to dispense with the imaging optics. In this case, LEDs and diodes can be bonded together on the illumination unit, which is then designed so that the light barrier of the optical unit is located after placement of the illumination unit between LED and diodes.
- the advantage of using the diode array is smaller size and lower total cost of the mobile device.
- a Farby-Perot filter array with a plurality of different central wavelengths can be used, which is placed on a substrate or directly on the pixels of a CMOS / CCD array. Since the individual pixels only reach specific wavelengths of light, location information can be extracted from the light scattered back from the skin. In addition to determining the depth of the measured concentrations, these also enable a separation of signal and scatter, which increases the accuracy of the measurement.
- a manufactured according to application EP 2057446 Fabry-Perot Filter array also has the advantage that it can be produced inexpensively despite high spectral resolution.
- Figure 9 shows the process of determining nutritional status, physical endurance capacity (V0 2 max) and life style adoptedem stress
- the spectral information can be transmitted via Bluetooth, WLAN or USB to a mobile phone or a computer and transmitted from there to a central server, which evaluates the data and displays the result on the user interface. Transmission and processing of data can be carried out as described in DE 10 2006012 681.
- the user receives an application software. After installation, he can automatically connect to the portal and the central server by activating an app on his computer or mobile phone. After registering with the server in a first step, all results are then displayed in a secure and only accessible area.
- the user When the user is connected to the portal / server for the first time, or before the start of a measurement, he or she can fill out a kind of history questionnaire, which automatically assigns the measured result and the answers given. In this way, the causes of measurement results can be identified.
- additional correction algorithms can also be located on the server which compensate for assembly or production tolerances, so preferably for all devices uniform algorithm can be used.
- the correction algorithms can be determined during the assembly of the devices and stored either in the mobile measuring device and in the data transmission to the central server or they are transmitted after the assembly process with a device identifier directly to the server.
- the user When registering the user, in addition to certain personal identification data (including billing requirements), the user must also transmit a measurement spectrum of their mobile measuring device. In addition to the spectral information, this measuring spectrum also contains the device identifier, so that it is then possible to associate the measuring person and the measuring device.
- To analyze the measurement data can then be the correction algorithm that was determined during the assembly for the respective meter. This procedure has the advantage that no device number has to be transmitted by the customer manually or by scanning a barcode.
- a preferred solution on the server may have an additional database containing detailed information about the ingredients of food, e.g. For example, the amount of antioxidants (vitamins), protein, fat or carbohydrates, calories, etc. content.
- the user can automatically calculate the amount of ingredients added to the body by selecting foods. For example, for foods that he has consumed on that day or that he wants to consume in the coming days or the entire week. Comparing the calculated amount of antioxidants with the carotenoid level measured with the mobile device in the skin optimizes dietary habits, e.g. by choosing better suitable foods with higher antioxidant content. At the same time, this comparison also allows an assessment of stressful lifestyle factors (see anamnesis questionnaire) and thus also supports a targeted change in behavior. In this way it is possible to improve preventive health behavior overall.
- the customer can choose from a database another trader or manufacturer for his fruit or vegetables, if the comparison between measurement and calculated antioxidants low the effectiveness of the food shows.
- Coaching information about manufacturers and suppliers in close proximity the user receives from the database hosted on the server.
- the client may also receive individual coaching through an expert database, which informs him of his measurement results and using the goals, preferences (preferred foods, sports activities, lifestyle, etc.) entered by the customer in the database, but also handicaps (eg allergies, musculoskeletal system, physical handicaps) makes individually tailored suggestions (eg special cooking recipes, training plans), to improve the antioxidant level and / or the physical endurance capacity. If the customer agrees to receive all available information on the basis of the measured result, a very individual coaching is possible, which helps him to significantly improve his health status with the help of biofeedback.
- an empirical prevention value is determined which reflects the current status of the user in his efforts to improve his or her health Preserving his health reflects.
- the relationship between the two measured values may be e.g. in a normalized scale, with the help of a special function, within certain limits, be multiplicative, so that a high value on the one hand offsets a low value on the other hand.
- Both measured values can also be located in a two-dimensional coordinate system, thus enabling the identification of health and risk areas in which the user is currently located. Since all measurement data is stored on the server, a preferred solution based on the past can also calculate the future course of the prevention value, showing the user where he will be in the future and what impact his present behavior will have in the long run.
- the meaningfulness of the prevention value can be further increased if the calculation takes into account the distance covered by walking / running during the day (eg by using an electronic pedometer).
- the user must store the data in the database (eg in the medical questionnaire).
- An interesting and user-friendly application in this sense is when the spectroscopic integrated into a body scale. Every morning, when the user measures his body weight barefoot on the scales, the carotenoids can be measured automatically, because the sole of the foot, like the palm, is an ideal place to measure the antioxidants. Physical endurance performance can also be determined at this location.
