6 and 7, the portable urine analyzer 300 has a mounting groove 311 for inserting the urine test kit 100 into the housing 310, and the inside of the housing 310 functions as a dark room. and measuring the reflection values for each color of the PCB 320, the LED 330, and the reagent pad unit 12 of the urine test strip 10 inside the housing 310, respectively. The sensor 340 is disposed, the LED 330 and the detection sensor 340 are disposed on the upper part of the urine test kit 100 disposed in the mounting groove 311 , and the LED 330 mounted on the PCB 320 . A diaphragm 350 is disposed between and the detection sensor 340 , and a lens 360 for a uniform optical effect is disposed under the LED 330 .

The PCB 320 is equipped with a low-power Bluetooth module (not shown) and a USB port (not shown), and can transmit/receive data to and from a smartphone (not shown) through the low-power Bluetooth module, and provide health to the smartphone. An application that provides a care service is installed, and it is possible to perform commands such as power on/off of the portable urine analyzer, device calibration, measurement, etc., and transmit the measured data to the management server 400 (see FIG. 1), and urine Analysis results and the like may be provided to the user.

The USB port also serves the purpose of communicating with a PC or a laptop computer, but another important purpose is to supply power to the portable urine analyzer so that it is possible to omit the installation of accessories such as an adapter or a battery to the portable urine analyzer, thereby improving portability. can be promoted

The LED 330 is sequentially irradiated with light in the red (R), green (G), and blue (B) wavelength bands to the urine test strip 10 of the urine test kit 100 .

Thereby, the urinalysis strip 10 generates concentration distribution and reflected light corresponding to changes in concentration.

The detection sensor 340 is a photodiode and optically reads a change in the color of the strip by measuring the reflectivity reflected from the urine test strip.

In the measurement method using the portable urine analyzer 300 configured as described above, the reflectivity (R, G, B standards) for each wavelength is calculated using Equation 1 below to determine HSI (Hue (hue), Saturation (saturation), Hue (color) is obtained according to the Intensity) model.

The H value according to the above formula has a value of 0 to 360, and has a value of 0 for red, 120 for green, and 240 for blue. And, H value can be applied to occult blood test, protein test, glucose test, acidity test, and concentration test of specific gravity without any abnormality.

In addition, the H value is often difficult to determine when saturation is low due to the characteristics of Hue (hue). Saturation), so there is a limit to the judgment based on the color value according to the HSI model, so it is necessary to use other criteria.

Accordingly, the concentration is determined using Equation 2 below, which is a new standard for classifying colors at a ratio of red (625 nm) and green (530 nm).

Y: Concentration determination value

In a test using an actual urine sample, in the case of bilirubin test, urobilinogen test, ketone body test, nitrite test, and white blood cell test, it is better to use T as an index of judgment, and for other component tests, it is better to use H as an index for judgment better results can be obtained.

The urine test device according to the present invention as described above can contribute to the improvement of public health by making a small portable urine analyzer 300 that can fit the urine test kit 100 and distributing it to consumers at low cost, and has high accuracy, Since it can be linked with the communication network of a portable telecommunication company, it can be used conveniently anytime, anywhere, and has the advantage of facilitating the establishment of a home treatment and telemedicine system.
