Description

The present invention relates to an apparatus and method for easily performing a urine test on humans or animals via a user terminal. Unlike the conventional urine test, the purpose is to provide a technology that generates test results immediately when urine is attached to the urine strip with a smartphone application and corrects problems that may occur when generating existing test results.

A urination test means a test for semi-quantitatively detecting various types of wastes excreted as urine by examining physical properties such as color and turbidity of urine.

In the case of the conventional quantitative test method in which results are expressed numerically, the quantitative value cannot be confirmed at the site of urine collection, and the urine sample must be transferred to the laboratory and then subjected to the test procedure. It takes more than a day to receive it.

As a result, the accuracy and reliability of workplace checkups and student checkups, which require screening multiple individuals for various diseases at low cost in a short time, are not as accurate and reliable as compared to quantitative tests. However, it became necessary to confirm the test results immediately at the urine collection site (POCT: Point of Care Testing).

In addition, in the drawings, parts that are not related to the description are omitted in order to clearly describe the present invention, and similar parts are denoted by similar reference numerals throughout the specification.

Throughout the specification, when a part is "connected" to another part, it means not only "directly connected" but also "electrical It also includes cases where it is “directly linked”. In addition, when a part "includes" a certain component, it does not exclude other components, unless there is a statement to the contrary. means

The following embodiments are detailed descriptions to aid understanding of the present invention, and are not intended to limit the scope of rights of the present invention. Therefore, inventions of the same scope that perform the same function as the present invention shall also belong to the scope of the present invention.

FIG. 2 is a diagram showing the configuration of a system for performing a urine test according to one embodiment of the present invention.

As shown in FIG. 2, a system for performing a urine test can consist of a user terminal 100, a urine strip 200, and a server 300. As shown in FIG. Also, although not shown in the drawing, the user terminal 100 and the server 300 are interconnected through a communication network.

According to an embodiment of the present invention, a user captures a urine test strip with urine on the user terminal 100 for a urine test, generates a test image, and corresponds to each test item area of the urine test strip in the test image. RGB values are extracted for each of a plurality of pad areas to generate first RGB values for each inspection item.

At this time, the pad region means a region provided on the urine strip 200 and coated with a reagent for testing components contained in urine. Therefore, each reagent has its own standard hue, and when it reacts with urine, it changes to a different hue depending on the health condition of the subject. The first RGB values are the RGB values extracted for the hue of such discolored pad areas.

Further, according to an embodiment of the present invention, a first ratio value is generated through a specific gravity RGB value extracted from a specific gravity pad region and a first RGB value among inspection items, and a standard ratio is obtained. A numerical value for each inspection item is calculated by comparing a second ratio value, which is a ratio between the specific gravity calculated through the color table and each inspection item, with the first ratio value. . Here, the specific gravity is a test item that varies depending on the degree of protein removal in the glomerulus, and in the case of existing urine strips, the specific gravity is simply used to determine the presence or absence of kidney disease.

At this time, the standard colorimetric table defines all hues that can be expressed in the pad area corresponding to each inspection item for urine inspection.

First, the reason why the present invention does not directly compare the first RGB values calculated by the urine test strip 200 with the RGB values calculated by the standard colorimetric table is that the concentration of urine varies depending on the condition of the body of the subject. This is because external factors may play a role, and test results may vary depending on the condition of urine. Therefore, the present invention divides the specific gravity RGB values extracted by the specific gravity by the first RGB values and the RGB values calculated by the standard colorimetric table to generate the ratio values, which are then compared.

In addition, the reason why the urine test is corrected based on the specific gravity in the present invention is that most of the conventionally sold urine test strips include the item of specific gravity, and this is utilized.

As an additional embodiment, the first ratio value and the second ratio value can be calculated by replacing the specific gravity RGB value with the RGB value of the creatinine concentration among the test items instead of the specific gravity RGB value. In this case, test items for creatinine should be provided on the urine strip so that the RGB values for creatinine can be measured. Alternatively, the measured RGB values for creatinine can be received by the user terminal via a separate analyzer.

According to an embodiment of the present invention, the user terminal 100 may mean a terminal for urine examination.

It is also possible to receive a printed inspection image.

Also, first RGB values are generated for each inspection item in the generated inspection image. The ratio between the second RGB value and the specific gravity RGB value generated through the standard colorimetry table is compared with the ratio between the first RGB value and the RGB value for the specific gravity on the inspection image.

Conventionally, the urine test strip 200 has the shape of a stick. It does not limit the range.

In one embodiment of the present invention, the server 300 can perform a urine test instead of the user terminal 100. FIG.

For example, when a test image is received from the user terminal 100, the first RGB values are extracted from the received test image, and the second RGB values are generated using the standard colorimetric table as described above. It is characterized by comparing the value with the specific gravity RGB value. Therefore, as an alternative embodiment, the server 300 may be omitted from the system of the present invention and the invention implemented via only the user terminal 100 and the urine test strap 200. FIG.

Meanwhile, the communication network serves to connect the server 300 and the user terminal 100 . That is, the communication network means a communication network that provides a connection path so that the user terminal 100 can transmit and receive data after connecting to the server 300 .

Further, the communication module 110 can serve to receive data requests from the server 300 and transmit data in response thereto.

Here, the communication module 110 may be a device including hardware and software necessary to transmit and receive signals such as control signals or data signals via wired/wireless connections with other network devices.

As an additional embodiment, the communication module 110 need not be provided in the user terminal 100 if the server 300 is omitted from the system implementing the present invention.

Memory 120 records a program for performing a urine test. It also serves to temporarily or permanently store data processed by the processor 130 . Here, the memory 120 may include magnetic storage media or flash storage media, but the scope of the present invention is not limited thereto.

Processor 130 is a kind of central processing unit that controls the overall process for performing a urine test. The steps performed by processor 130 are described below with reference to FIG.

Here, the processor 130 may include any kind of device capable of processing data like a processor. Here, a "processor" is a hardware-implemented data processing device having circuits physically structured to perform the functions expressed in, for example, code or instructions contained within a program. can mean a device. Examples of data processing devices built in hardware include microprocessors, central processing units (CPUs), processor cores, multiprocessors, and ASICs (applications). -specific integrated circuit), FPGA (field programmable gate array), etc., but the scope of the present invention is not limited thereto.

The database 140 may store test images taken for the urine test, second RGB values corresponding to a pre-stored standard colorimetry table, test results, and the like.

Also, in order for the camera of the user terminal 100 to correctly recognize the hue of the urine test strip 200, the standard colorimetry table may be photographed in advance to correct the hue, and the set value for the correction result may be stored in the database 140. can.

FIG. 4 is an operational flowchart illustrating a method for performing a urine test, in accordance with one embodiment of the present invention.

As shown in FIG. 4, in order to perform a urine test, first, the urine test strip 200 with urine is photographed by the user terminal 100 to generate a test image (S310).

The standard colorimetry table and the second RGB values may be pre-calculated and stored in advance prior to beginning the urine test.

Also, the user terminal 100 may be provided with an indicator for guiding the position of the urine test strip 200 when taking an image of the urine test strip 200 . By placing the urine test strip 200 at the position guided by the indicator and photographing it, the user can easily generate a test image for extracting test items and RGB values. However, when the urine test strip 200 is photographed, if the surrounding illuminance is lower than the preset level, an alarm message requesting improvement of the photographing environment may be provided to the user. In addition, if the image quality of the test image is below a preset value or the position of the urine test strip 200 on the test image is above a preset error range, the user terminal 100 requests photography. It will be possible to provide an alarm message to the user.

After step (S310), the user terminal 100 generates the first RGB values for the pad area of each inspection item from the inspection image (S320).

As an additional embodiment, the step of receiving the inspection image or the first RGB values from the other user terminal 100 or the server 300 and capturing the image (S310) may be omitted.

After that, the user terminal 100 generates a first ratio value using the first RGB value and the specific gravity RGB value extracted from the specific gravity pad area among the inspection items, and calculates the first ratio value according to the standard colorimetric table. A numerical value for each inspection item is calculated by comparing the second ratio value and the first ratio value, which are ratios between the specific gravity calculated through and each inspection item (S330).

At this time, as described above, the second ratio value is the value of the pad area of the inspection item in contrast to the hue that can be expressed in the specific gravity pad area based on the RGB values extracted from the standard colorimetric table. It can mean the ratio between hues.

That is, according to a plurality of health conditions of the user, the second RGB values regarding all colors that can be expressed by the pad area of each inspection item are calculated, and all colors that can be expressed by the pad area of each second RGB value and specific gravity are calculated. Calculate the ratio between the RGB values of . In addition, the work of constructing an RGB ratio table including a plurality of second ratio values for each inspection item can be performed before step (S310).

At this time, the first and second ratio values may have a preset margin range. Therefore, in step (S330), it is determined whether the margin range of the first ratio value is included in the margin range of the second ratio value, and numerical values for each inspection item are calculated.

After the step (S330), a step of determining the health condition of the subject for each test item based on the numerical value calculated corresponding to the test item and providing the test result to the user may be further included.

At this time, the user terminal 100 indicates whether the health condition of the subject is normal/abnormal based on the numerical value calculated as the test result by a simple symbol such as O/X or "normal"/". It is possible to prevent confusion caused by providing too much information to a non-expert by providing it in the form of a message such as "abnormal".

In addition, as an additional embodiment, when an abnormal determination is displayed for health, the user terminal 100 provides a message (eg, an abnormal suspicious message, etc.) to the user to recognize that the test may be uncertain. A message requesting retesting can be provided with the

As an alternative embodiment, a comparison value for test results of a particular user and other users can be calculated based on the difference between the first RGB values of the particular user and the previously stored first RGB values of other users. .

For example, comparing the RGB value of ascorbic acid extracted from the inspection image of person A with the RGB value of ascorbic acid extracted from the inspection image of person B, and comparing which person has the lower ascorbic acid value. become able to.

FIG. 5 can be an illustration of a table for comparing ratio values based on RGB values, according to one embodiment of the present invention. RGB values are configured such that each of the R value, G value, and B value has a numerical value, but in the table of FIG. It is created on the assumption that it is configured based on one value.

As shown in FIG. 5, a specific gravity pad area 510, an ascorbic acid pad area 520, and a ratio table 530 can be seen in the drawing.

The specific gravity pad area 510 and ascorbic acid pad area 520 illustrated in the drawings can be a collection of tables that can be included in a standard colorimetric table and expressed in response to the test subject's urine.

At this time, the number of colors that can be expressed is different for each inspection item, and as described above, the specific gravity pad region 510 included in the universal inspection item can be used as the inspection reference.

A ratio table 530 may represent a second ratio value for specific gravity that ascorbic acid can have.

For example, the first column could be the four grids that ascorbic acid can have, and the second column would be the standard hue RGB values (second RGB values) that each grid has. is. In the illustration, these are assumed to be 10, 20, 30 and 40 respectively.

In fact, the reagents of the urine test strip 200 may develop color in intervals with continuous values, rather than being perfectly matched in hue as in the ascorbic acid pad region 520 of the standard colorimetric chart. Thus, like the third column, the actual second RGB values will have a preset margin.

Further, in FIG. 5, the specific gravity pad area 510 is composed of 7 grids, and the difference in specific gravity values is assumed to be 0.005. As a result, when the specific gravity is divided into the RGB values for each grid, the grid value of each ascorbic acid appears as an RGB value ratio table 530, as in the yellow shaded area. Therefore, if the first RGB value falls within the actual margin range, the corresponding health condition is determined as the health condition of the user.

At this time, when the margin value is large, the range of each second ratio value in the ratio table is widened, and there may be a section where different second ratio value ranges overlap. If the first ratio value belongs to the overlapping section, the user terminal 100 may further include correcting the overlapped result value after step S330.

For example, although the second ratio values illustrated in FIG. 5 were calculated based on specific gravity, other second ratio values calculated using other components, including creatinine, in addition to specific gravity. Through the comparison of , a correction can be made so that the first ratio value can belong to the non-overlapping interval. On the other hand, it is also possible to calculate a plurality of second ratio values corresponding to each of the R value, the G value, and the B value, and to correct the inspection result through comparison of the first ratio values. This is an example and corrections can be made in other ways as well.

FIG. 5 illustrated in the present invention is an example for explaining the present invention, and the numerical values and colors described in the drawings do not limit the scope of the present invention.

An embodiment of the present invention can also be embodied in the form of a recording medium including computer-executable instructions, such as program modules, executed by a computer.

Computer-readable media can be any available media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. Computer-readable media may also include computer storage media. Computer storage media includes volatile and nonvolatile, separable and non-separable implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules, or other information such as data. Includes all type media.
