Description

Measuring urine sugar concentration device

The present invention relates to a device capable of measuring liquid concentration, in particular to a device capable of measuring urine sugar concentration.

The high or low value of urine sugar indicates that the glomerular and filtrated blood sugar is too high, so that the renal tubules cannot fully absorb it, and it is excreted in urine as urine sugar. Generally speaking, when the blood sugar exceeds 180mg/dL, there will be sugar in the urine. If the urine sugar test results are positive, it means that the subject may have risks such as diabetes, pancreatitis, liver disease, and thyroid disease.

High urine sugar is often one of the causal relationships that determine high blood sugar. However, because the current blood sugar test is an invasive blood test, it causes a psychological burden on the subject, thus reducing the willingness of the subject to continue testing. Therefore, it is often found that the above-mentioned lesions have been caused by the high blood sugar level after the testee delays the test.

In addition, the urine glucose test is currently mainly based on the enzyme method, of which the glucose oxidase method is the most common. However, although the cost of test paper detection is low, for end users, the test paper measurement time needs 30-60 seconds, and there is no real-time. Furthermore, human eyes may easily cause human error when interpreting the color change of the test paper, thus lacking in efficiency. At the same time, there is a storage problem with the test paper, which is easy to deteriorate due to air and moisture, thus affecting the judgment of the performance of urine sugar.

When the second incident light beam enters the inside of the main body, the second incident light beam hits the first light-transmitting surface, exits the inside of the main body from the first light-transmitting surface, enters the first accommodating space, and passes through the first light-transmitting surface.

Please refer to FIG. 4A to FIG. 4C , which are schematic diagrams of reflected light of the apparatus for measuring urine sugar concentration of the present invention. As shown in the figure, the light-emitting surface 14 of the main body 1 is arranged on the side opposite to the light-incident surface 15, and the first incident light beam L1 reflected by the interface 100 passes through the light-emitting surface 14, the first light-emitting port 21 of the housing 2, and After the second light outlet 22, it is incident on the first light sensor D1. It can be seen from the principle of optics that to measure the first incident light beam L1 passing through the light exit surface 14, the first light exit port 21 and the second light exit port 22, it is necessary to set the angle and area of the light exit surface 14 and the first light exit port 21 and the second light exit port 22. The aperture of the light outlet 22 is configured. Furthermore, according to Snell's Law, given the refractive index of the medium of the main body 1 and the incident angle of the first incident light beam L1 incident on the interface 100, the first incident light beam L1 can pass through different media The medium refractive index of urine Q is calculated from the range of reflection angles produced by the interface of refractive index (different solutions) 100°. The larger the refractive index of urine Q, the more light is refracted, and the less reflected light is, and the reflected light of the first incident light beam L1 received by the first light sensor D1 is less (as shown in Figure 4A and Figure 4B shown), therefore, the preset inclination angle θ and area of the light-emitting surface 14 can be defined and configured according to the range of the first incident light beam L1 incident on the range of the medium refractive index of different urine Q, and the corresponding reflection angle range, And calculate the caliber size of the first light exit 21 and the second light exit 22, that is, the preset inclination angle θ and the preset area of the light exit surface 14 and the apertures of the first light exit 21 and the second light exit 22 are based on The reflection angle of the first incident light beam L1 from the interface 100 is set, and the preset inclination angle θ is set with the interface 100 as a reference angle.

In a preferred embodiment of the present invention, the first light source S1 is arranged in a through hole 261 of the outer wall 26 of the casing 2, and is arranged corresponding to the normal position of the center of the light incident surface 15 of the main body 1, so that the first light source S1 The incident light beam L1 can averagely enter the light incident surface 15 . The first light sensor D1 is disposed on the second light outlet 22 of the casing 2 so as to receive the first incident light beam L1 passing through the light outlet surface 14 , the first light outlet 21 and the second light outlet 22 evenly.

Please refer to FIG. 5A to FIG. 5D , which are schematic diagrams of the first incident light beam entering the device for measuring urine sugar concentration according to the present invention. Actually, in order to measure the reflected light after the first incident light beam L1 is incident on the main body 1 and to measure the light after the second light beam L2 passes through the urine Q, in the embodiment of the present invention, the first light source S1 and the second light source S2 include halogen lamps, gas lamps, lasers, LEDs, or other light emitting elements. For the reflected light after the first incident light beam L1 is incident on the main body 1, the light beams generated by the light sources used are emitted 360 degrees outward, and for the first half of the light incident on the main body 1, It can be divided into four parts of light as shown in Fig. 5A to Fig. 5D. As shown in FIG. 5A , when the first incident light beam L1 is incident on the interface 100 of the main body 1 , the reflected light is emitted toward the light-emitting surface 14 and enters the first light sensor D1 . As shown in Figure 5B, when the first incident light beam L1 is incident on the main body 1, since there is no surface or interface 100 that can cause reflection in the incident direction, the incident light beam is directly directed towards the main body 1 for external injection. As shown in FIG. 5C, when the first incident light beam L1 is incident on the light-emitting surface 14 of the main body 1, since the incident angle of the first incident light beam L1 just forms an angle of total reflection with the light-emitting surface 14, the reflected first The incident light beam L1 is incident toward other directions of the qian main body 1 , and is emitted toward the outside of the qian main body 1 . As shown in FIG. 5D, when the first incident light beam L1 is incident on the third light-transmitting surface 13 of the main body 1, the angle of reflected light generated by it is not emitted toward the light-emitting surface 14, but toward other parts of the main body 1. The direction shoots outward. Accordingly, the first light sensor D1 disposed at the second light outlet 22 only receives the reflected light incident on the interface 100 of the main body 1 .

Please refer to FIG. 6 , which is a schematic diagram of the relationship between urine concentration and absorbance in the present invention. Since the concentration of urine Q will cause a difference in absorbance, the concentration of urine Q can be calculated by measuring the absorbance of urine Q. According to the Beer–Lambert law, when a parallel light is incident on the sample vertically, the light-absorbing substance of the sample absorbs part of the photon energy, which weakens the intensity of the transmitted light, and the absorbed energy (A) is related to the sample absorption coefficient ( α), optical path (sample length) (L), and concentration (c) are positively correlated, expressed as follows:

The absorbed energy can be regarded as the absorbance (A), so when the light passes through the sample, part of the energy is absorbed by the sample, and the rest of the light passes through the sample, so the energy of the incident light (I ₀ ) and the transmitted light (I) can be The absorbance of the sample is calculated by the difference, and the absorbance is defined as follows

Moreover, after the second incident light beam L2 is incident on the first reflective surface 16, it is reflected by the first reflective surface 16 and then transmitted to the urine Q. The urine Q absorbs part of the photon energy to weaken the intensity of the transmitted light, and then passes through the second light reflection Surface 17 is reflected to the second light sensor D2. The higher the concentration of urine Q, the more light energy is absorbed, so the intensity of transmitted light is weaker. From the ratio of light source intensity to transmitted light, the absorbance can be known, and then the concentration of urine Q can be calculated.

Please refer to FIG. 7 , which is a schematic diagram of the relationship between urine sugar concentration, absorbance and refraction in the present invention. Since the concentration of urine Q is different, the light absorption ratio of light will also be different. Therefore, different urine concentrations will have different urine sugar characteristic curves A, B, and C. However, the present invention can measure the absorbance and refraction of urine, and judge the urine sugar characteristic curves A, B, and C by measuring the absorbance of urine, and then measure the refractive index after the light enters the urine Q, namely The refractive index of urine, according to the refractive index and the urine sugar characteristic curves A, B, and C judged based on the absorbance, calculates the corresponding urine sugar concentration. In one embodiment of the present invention, the casing 2 further includes a storage module (not shown), which stores a database, and the database contains a plurality of urine sugar characteristic curves for the processing module to quickly calculate and compare urine sugar concentration.

For example, the absorbance corresponding to the urine sugar characteristic curve A is a%, the absorbance corresponding to the urine sugar characteristic curve B is b%, the absorbance corresponding to the urine sugar characteristic curve C is c%, and a>b>c, and through this The urine refractive index measured by the invention is n. Accordingly, when calculating the urine sugar concentration, the urine sugar characteristic curve A can be determined based on the absorbance a% calculated above, and then the corresponding urine sugar characteristic curve A and the calculated refraction can be calculated as n The urine sugar concentration is x (mg/dl).
