Description

Non-invasive biometric positioning-based correction system and method using multiple sensors {NON-INVASIVE BIOMETRIC MEASUREMENT BASED CALIBRATION SYSTEM AND METHOD USING MULTIPLE SENSORS}

The present invention relates to a non-invasive biometric information positioning-based correction system and method using multiple sensors.

Recently, non-invasive technologies are not supported by IT companies such as Apple, Google, and Samsung, as well as leading medical companies such as Medtronics, Dexcom, GE, and Philips, and companies such as GlucoTrack, ClucoWage, and CNOGA Medical. Research and development for invasive medical device products are being actively conducted.

In this regard, in the light-based non-invasive field, various wavelengths such as 580 to 900 nm and 850 to 1380 nm have been continuously studied since the early 2000s. And recently, a plurality of light sources having a wide wavelength band are used to increase the related reliability. However, since the complexity of post-processing is increasing due to noise reduction between measured data, a narrow-band based multi-light source processing technology capable of minimizing noise is required.

On the other hand, there is a problem that a number of noise processing occurs due to the'fluctuation source' and the frectal phenomenon of the measuring source due to the thickness and characteristics of the skin that are different for each person, and external light interference. Research is being conducted to minimize noise by using various complex sensor sources such as thermoelectrics.

In the previous measurement and analysis problems, the noise that has the greatest influence depends on the thickness and characteristics of the skin, which differs from person to person. Conventionally, a number of studies using information measured on human fingers and earlobe have been conducted, but separate studies for correcting the aforementioned noise are very insufficient.

In order to correct skin characteristics such as finger and earlobe of a person having 100 color characteristics of 100, a lot of data is required, and one of the fastest methods is to verify the deviation using a light source composed of a recent MEMS LED Array. .

However, these MEMS LED Arrays have different specificities such as individual LED wavelength length, narrow band range, and lens characteristics for each manufacturer, and the photodiode of the receiver also has specific characteristics according to the manufacturer, so crossover according to such deviations A correction method through verification is required. In addition, there is a problem in that the blood glucose level is not constantly measured depending on the amount of other components in the blood.

1 is a diagram for explaining a relationship between a reflective light source and skin characteristics.

When measuring biometric information non-invasively using the light source P1, the refractive index of the subcutaneous tissue and the thickness of the epidermis have a great influence on the measurement result.

In order to know the exact transmission and absorption rate of light (P1), the intensity of the light source (P1) can be analyzed while penetrating the epidermis and analyzing the capillaries and arterioles of the papillary in the dermis. It is most important to control.

In this case, when the light source P1 is used, capillary vessels and arterioles of the papillary dermis can be analyzed in the human dermis through the reflection method, and the transmittance of the arterioles can be confirmed through the transmission method.

However, when the light source (P1) is used, the refractive index of the subcutaneous tissue and the thickness of the epidermis have a great influence on the measurement result. Therefore, in order to know the accurate light transmission and absorption rate, the tissue has transparency to overcome the noise of the epidermis. The intensity of the optimized light source P1 that has no effect on is important.

In particular, since the thickness of the epidermis and the dermis are different for each person, it is necessary to additionally introduce a correction method to accurately verify the characteristics of the main component to the response of light P1 in human blood.

Hereinafter, a non-invasive biometric information positioning-based correction system 100 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 5.

2 is a block diagram of a non-invasive biometric information positioning-based correction system 100 according to an embodiment of the present invention. 3 is a diagram for describing the multiple sensors 110.

The non-invasive biometric information positioning-based correction system 100 according to an embodiment of the present invention includes a multi-sensor 110, a biometric information measurement unit 120, a correction unit 130, and an output unit 140.

The multi-sensor 110 is composed of a transmissive-based sensor and a reflective-based sensor, and specifically, first and second light source array sensors 111 and 115, and first and second photo array sensors 113 and 117 It may include.

Referring to FIG. 3, the first light source array sensor 111 is disposed so that the light source penetrates the user's skin on a transmissive basis.

In addition, the first photo array sensor 113 is disposed perpendicularly to the other side facing one side of the first light source array sensor 111 and spaced apart at a predetermined interval in the vertical direction, and is output from the first light source array sensor 111 and is The light source that has passed through the blood vessel is received.

The second light source array sensor 115 is disposed so that the light source reflects the user's skin on a reflective basis.

In addition, the second photo array sensor 117 is disposed to be spaced apart from the second light source array sensor 115 in a horizontal direction at a predetermined interval, and is output from the second light source array sensor 115 to receive light sources reflected from the skin, precisely blood vessels. do.

Meanwhile, the first and second light source array sensors 111 and 115 may be composed of LED devices capable of generating three or more wavelengths in the range of 480 nm to 1380 nm, for example, IR, RED, GREEN, ORANGE, etc. It can be composed of an LED device.

In addition, the first and second light source array sensors 111 and 115 may be provided with a configuration for condensing the generated light sources, for example, a predetermined optical system for focusing the light sources.

For example, the light source generated from the LED may be condensed by the light condensing unit and incident on a predetermined portion of the finger through a hole in the device in contact with the finger.

The incident light sources are scattered and reflected by blood components in the user's body part.

In addition, the transmitted or reflected light source is collected by a light receiving unit of a predetermined optical system and transmitted to the first and second photo array sensors 113 and 117.

On the other hand, the photo array sensor is packaged like a single optical sensor, which can individually measure 580nm, 640nm, 830nm, 880nm, 940nm, etc., matching individual narrowband LED light sources. It is a group of receiving sensors that are composed of multiple dependently.

In this case, the first and second photo array sensors 113 and 117 may receive light sources from the first and second light source array sensors 111 and 115 in a predetermined unit.

The first and second photo array sensors 113 and 117 may be composed of three or more photodiodes to correspond to the first and second light source array sensors 111 and 115.

In addition, the first and second photo array sensors 113 and 117 may generate a fluorescence spectrum through a reaction of an electric signal for each light source by spectralizing the received light source, and using a predetermined sensing means to generate the spectroscopic fluorescence spectrum. It can detect and convert it into a certain electrical signal.

In addition, the analog-type electrical signal is converted into a digital signal, expressed as a voltage value having an accurate level value, and provided to a biometric information measuring unit described below for each individual wavelength frequency.

In this case, the first and second photo array sensors 113 and 117 may include a configuration for converting a corresponding analog value into a digital value or may be separately provided.

The biometric information measuring unit 120 collects biometric information from the user's blood based on the received voltage values measured from the first and second photo arrays 113 and 117, respectively, before and after pressure is applied to the user's body part. Measure.

Specifically, in the case of the transmission type, the biometric information measuring unit 120 is the wavelength of the light reflection coefficient due to absorption of the light source on the first body part of the user based on the received voltage value measured through the first photo array sensor 113. By analyzing the degree of change in blood, the hemoglobin value in the blood is measured with biometric information.

Similarly, in the case of the reflection type, based on the received voltage value measured through the second photo array sensor 117, the light source transmits and reflects on the user's second body part, and changes in the amount of polarization of the light are analyzed, The hemoglobin value at is measured.

As such, each measured hemoglobin value may be averaged or converted into a glucose value using weight analysis or the like.

At this time, the biometric information measuring unit 120 analyzes the degree of reception according to the wavelength of the light source from the received voltage value by the transmitted or reflected light source through the fluorescence spectrum, and analyzes the intensity of the fluorescence spectrum, the Raman spectrum, and the Beer spectrum. The hemoglobin value in the blood can be measured.

FIG. 4A is an exemplary diagram for explaining the absorption rate of a transmission type light source, and FIG. 4B is an exemplary diagram for explaining a reaction frequency by a reflection type light source.

Typically, before pressure is applied to a body part such as a finger, blood is filled in a blood vessel at the bottom of the finger contacting mechanism.

In addition to glucose and hemoglobin, water, red blood cells, white blood cells, electrolytes, cholesterol, and the like are present in such blood.

When such blood components are under pressure, most of them are pushed out to other places that are not under pressure, and blood components are minimized in the blood vessels of the finger area under pressure.

At this time, when analyzing the measurement area by reflection and transmission, the fluorescence spectrum received by the photo array sensor due to the light source array sensor is the value of the spectral current due to the Ramam characteristic in which molecules are scattered by the light source. It will be different for each wavelength.

In this way, the scattering of hemoglobin, which is the main component, is analyzed by a plurality of light sources between 480nm and 1380nm of the projected light source array sensor by the response frequency of light to the main component of white blood cells in blood vessels, and various components of red blood cells are During the reaction, an optical frequency component including a glucose component is scattered and the amount of blood sugar can be predicted through Raman analysis, which appears large at a specific wavelength.

In this process, the biometric information measurement unit 120 designates and removes the remaining elements other than the hemoglobin value and the glucose value among the biometric information that can be calculated from the measured received voltage value of red blood cells in the blood, so that the hemoglobin value in the blood and the The glucose value can be measured more accurately.

To this end, the biometric information measuring unit 120 accurately measures the hemoglobin value and glucose value by analyzing the difference in absorption and reflection of at least three wavelengths or more from the received voltage values from the first and second photo array sensors 113 and 117. can do. For example, the wavelength of electromagnetic waves used before and after pressure is applied to the user's body part may be within 1380 nm, and the upper light source frequency band is excluded as it may affect the internal tissues of the human body.

In addition, the biometric information measuring unit 120 may predict the amount of blood glucose by analyzing the Raman spectrum which is scattered about the amount of glucose and dissolved oxygen in the blood vessel among the fluorescence spectrum and is large at the corresponding wavelength.

The correction unit compares the biometric information measured by the biometric information measuring unit 120 with the invasive data D1 prepared in advance and calculates a correction value for correcting the output voltage of the multiple sensors 110.

In this case, an exemplary embodiment of the present invention uses the multiple sensors 110 to measure the accurate glucose value and hemoglobin value, and at the same time, the hemoglobin value and the glucose value measured by the invasion using the previously prepared invasive data (D1) are used as a reference. Can be used as a value.

Such invasive data (D1) may be previously measured and input by a blood glucose meter, a glucose meter, etc., and in an embodiment of the present invention, the invasive data (D1) only needs to be prepared once or only when necessary, and repeatedly It differs from the conventional invasive based technology in that it is not required.

The correction unit 130 compares the hemoglobin value and glucose value, which are invasive data D1 prepared in advance, and the hemoglobin value and glucose value obtained by the biometric information measuring unit 120, and the first light source array sensor 111 and A correction value for correcting one or more output voltages of the second light source array sensors 115 is calculated.

In addition, the correction unit 130 additionally calculates and outputs a correction value for correcting the timing of at least one of the first and second light source arrays 111 and 115 in addition to the correction value of the output voltage based on the comparison result. It can be provided as the unit 140.

The output unit 140 controls to increase or decrease the output voltage of the multi-sensor 110 based on the correction value calculated by the correction unit 130.

In this case, when the multi-sensor 110 is composed of the first and second light source array sensors 111 and 115 and the first and second photo array sensors 113 and 117, the output unit 140 is based on the correction value. Accordingly, it may be composed of a first output unit 141 that increases or decreases the output voltage of the first light source array sensor 111 and a second output unit 143 that increases or decreases the output voltage of the second light source array sensor 115. .

Thereafter, when the first and second light source array sensors 111 and 115 are driven according to the corrected output voltage, and the resultant measurement result is provided to the correcting unit 130, the correcting unit 130 returns the invasive data D1 ), it is possible to determine whether or not to perform an additional correction process.

Meanwhile, in an embodiment of the present invention, the light source array sensors 111 and 115, the photo array sensors 113 and 117, and the output unit 140 are not necessarily composed of two pairs, but are expanded to various numbers as necessary. It is possible.

5 is a block diagram illustrating the correction unit 130 and the output unit 140.

The correction unit 130 compares the invasive data D1 prepared in advance with a value measured by the biometric information measurement unit 120 to correct one or more output voltages of the first and second light source array sensors 111 and 115 A correction value for correcting the light wavelength timing and a correction value for correcting the light wavelength timing may be calculated, and for this, the LED control unit 131 and the light wavelength timing control unit 132 may be included.

The optical wavelength timing control unit 132 transfers the calculated optical wavelength timing correction value to the LED control unit 131, and the LED control unit 131 includes the optical wavelength timing information and output voltage information in the correction value, and the first and second output units ( 141, 143).

The first and second output units 141 and 143 receiving the digital signal-based correction values are converted into analog signals for driving the LEDs, and the first and second light source array sensors ( 111, 115) output voltage and light wavelength timing can be controlled.
