Definitions
- the invention relates to an electronic device for highly precise and precise determination of the temperature and detection of the heat of the human body, which enables a nonivasive determination of the glucose concentration in parts of the human body, in particular in human blood.
- the unit of the Celsius temperature is the degree Celsius (° C); it is the same size as the Kelvin.
- Expansion thermometers are contact thermometers which have to be brought into mechanical contact with the measurement object. With them the thermal expansion of a fluid (gas or liquid) or a solid substance is used for temperature measurement.
- thermometers filled with mercury are the best known and most frequently used measuring devices. These are easy to use and do not require any additional devices. With them, measuring accuracies between 39 ° C and 630 ° C can be achieved, which are generally only exceeded by resistance thermometers with great effort. Using a good mercury glass thermometer is in the range between
- thermometer In the case of the resistance thermometer, the temperature-dependent change in the electrical resistance is used as a measure of the temperature. Preference is given to metals and semiconductors whose changes in resistance are large and reproducible. The highest precision in thermometry is achieved with platinum, iron rhodium and germanium resistance thermometers in sections in the range from 1 K to 1340 K.
- thermocouples are the most frequently used electrical thermometers in the temperature range from 1 K to 3000 K. Although the measurement uncertainty is greater than that of the resistance thermometer, thermocouples are much easier to manufacture and have a small spatial extent a short response time and are particularly suitable for measuring temperature differences. Voltage compensators or high-resistance voltmeters are used to measure the thermal voltage.
- Suitable gases for steam pressure thermometers are helium, hydrogen, oxygen and nitrogen. These thermometers are often used in cryogenics. In the range of very low temperatures (0.5 K to 5.2 K), the helium vapor pressure thermometer is one of the temperature measuring devices with very high reproducibility.
- a temperature measurement method can be based on any known connection between a material property and temperature. In addition to the methods already described, e.g. the temperature
- REPLACEMENT LEAF The speed of sound in solids up to very high temperatures, the anisotropy of gamma radiation for T ⁇ 80 mK, the quadrupole nuclear magnetic resonance for 300 K>T> 20 K etc. can be used for temperature measurement.
- Biological rhythms of blood glucose close-knit blood glucose day and night profiles of normal people and the sick show commonalities such as rising in the evening, falling in the night, rising again in the early hours of the morning, despite very different external factors such as age, diet, illness, etc. These similarities seem to reflect an endogenous and vegetative period. Such periodic fluctuations are known as circadian rhythms. This means biological rhythms with a period of about 24 hours. This biological rhythm continues even when two important environmental periodicities such as light and ambient temperature are kept constant.
- both the functions of the whole organism and that of the individual organs and cells are subject to rhythms which are in a certain phase relationship to one another and to the periodic of the environment and are referred to as "circadian organization".
- rhythms which are in a certain phase relationship to one another and to the periodic of the environment and are referred to as "circadian organization”.
- Glycogen, glycogen synthase and phosphorylase and the corresponding blood glucose concentrations show a clear, parallel rhythm.
- the vegetative functions such as pulse, blood pressure, blood circulation, breathing and body temperature are subject etc. also a circadian periodic.
- the activity phases for example, last with individual fluctuations of 8
- the metabolism is catabolic. For example, body temperature, blood pressure and blood glucose concentration. Man is ready to work.
- the invention is based on the object, for the purpose of measuring the temperature of the human body (e.g. surface temperature, temperature in layers near the surface, body cavities and temperature gradients, etc.) and the detection of the heat of the human body to construct a device, the accuracy and precision of which of conventional devices for measuring temperature and recording heat. Furthermore, the present invention has the task of enabling temperature measurement and heat detection with a high spatial and temporal resolution.
- the temperature of the human body e.g. surface temperature, temperature in layers near the surface, body cavities and temperature gradients, etc.
- the present invention has the task of enabling temperature measurement and heat detection with a high spatial and temporal resolution.
- the invention is further based on the surprising finding that there is a high correlation between the circadian fluctuation in the glucose concentration of human glow and the circadian periodic of the body temperature measured at certain suitable points and the sensed heat. This suggests that body temperature and body heat be used to determine blood glucose.
- the invention accordingly describes a method which enables the precise determination of the concentration of blood glucose in the human body by means of extremely precise temperature measurement and heat detection, in a nonivasive manner, ie not harming the body and also contactlessly. The removal of capillary blood from the fingertip or earlobe required for conventional methods for determining blood glucose is therefore no longer necessary.
- a suitable mathematical evaluation algorithm according to the invention should allow the assignment of measured, recorded, processed temperature and heat data to glucose concentrations.
- At least one miniaturized thermistor (NTC resistor) known per se is used for temperature measurement.
- the NTC resistor is located in a suitable holder made of material with the lowest possible coefficient of thermal conductivity and forms a unit with it, the so-called sensor head.
- the geometry of the holder can be of various types. However, it either accommodates the NTC in a cavity in such a way that it is possible to measure the heat radiation emitted by the test object without contact, or it provides the NTC with a suitable place for (touching) measurement of heat emanating from the test object by heat conduction.
- the bracket also has the task of protecting the NTC from destruction or contamination.
- the measuring principle either requires, for example, two measurements in sequence (sequentially) with an NTC or a simultaneous measurement (simultaneous) with, for example, two NTCs. Therefore, a preferred design contains at least two, a particularly preferred design of the device according to the invention contains at least 3 NTCs.
- a preferred design contains at least two
- a particularly preferred design of the device according to the invention contains at least 3 NTCs.
- either two NTCs in an open cavity, spatially offset from one another, are used to measure thermal radiation
- the third NTC sitting on the surface of the holder or in the wall thereof is used to measure heat conduction
- one in an above NTCs sitting in an open cavity serve to measure the heat radiation
- two NTCs sitting on the surface of the holder or in the wall thereof, spatially offset from one another serve to measure heat conduction.
- the sensor head In a preferred design of the sensor head, it is made of wood or a similar material. In a particularly preferred design, the sensor head consists of a hollow body which is sealed tightly by touching or introducing the measurement object. With this arrangement, the measurement can take place under atmospheric pressure or under protective gas. Furthermore, the above Interior can also be evacuated. NTCs (with quasi massless leads) for contact and non-contact measurement are then in a vacuum. Evident interference can be minimized.
- a special electronic circuit converts analog measurement values with a resolution of 24 bit into digital data. This enables temperature measurements with resolutions ⁇ 10 -4 K.
- a (one-chip) microcomputer containing the evaluation algorithm compares the measurement data with
- a digital / analog converter forwards the processed data to a suitable display (liquid crystal display, monitor, etc.), which shows the determined glucose concentration as a numerical value (optionally in mg / dl or mol / 1).
- both the device according to the invention and the individual parts are calibrated.
- the relationship between the measured variables and glucose concentrations is then established in the form of a calibration or analysis function. This is done very simply as follows:
- a measurement process (sequential or simultaneous; see above) provides at least two measured values X ... and X 2i '.
- the blood glucose concentration is determined in a recognized, conventional manner (invasively) with each measurement process. Measurements therefore result in 2 measured values X. and n
- auxiliary functions are created, for example by the measured variable X, and X_ in relation to each other taking into account the biochemical, biological processes of the human body.
- the auxiliary function proves to be particularly necessary to ensure that the matrix effects are to develop analysis methods independent of people.
