Description

Apparatus and method for performing a simple urine test {APPARATUS AND METHOD FOR PERFORMING A SIMPLE URINALYSIS}

The present invention relates to an apparatus and method for simply performing a urine test on a person or animal through a user terminal. Unlike conventional urine tests, the purpose is to provide a technology that generates test results as soon as urine gets on a urine strip with a smartphone application and corrects problems that may occur when generating existing test results.

A urinalysis refers to a test that examines the physical properties of urine, such as color and turbidity, and semi-quantitatively detects various types of waste products excreted through urine.

In the case of the conventional quantitative test method in which the results are expressed in numbers, the quantitative value cannot be confirmed at the urine collection site and the urine sample must be transported to a laboratory and then go through testing procedures, so it takes more than a day to transport the sample and receive the results. do.

Accordingly, in workplace examinations and student examinations that require screening for the presence or absence of various diseases at a low cost for a large number of subjects within a short period of time, test results are confirmed immediately at the urine collection site, even if the accuracy and reliability are not as good as quantitative tests. This need (POCT: Point of Care Testing) has led to the need for testing.

For this reason, a method of performing a urine test was developed in which urine is applied to a urine test strip equipped with samples of each component in a predetermined area and the color of each sample changes as a method of urine testing.

Figure 1 shows an example of a standard colorimetric table used conventionally.

Referring to FIG. 1, the color of each test area on a urine test strip soaked in urine is visually read using the color of a standard colorimetric table, or the test is performed using a separate analysis device to increase convenience.

This urine test has the advantage of being a non-invasive method that allows samples to be collected easily without causing any pain to the examinee.

However, urine tests have the problem that the amount of urine excreted varies greatly depending on certain factors, such as the amount of water consumed, foods with diuretic effects, and whether medicines are consumed. In other words, due to the effects of concentrated urine and diluted diluted urine, there is a limitation in that spot urine samples such as urine test strips are greatly affected by the actual concentration depending on the amount of urine.

Additionally, the first ratio value and the second ratio value can be calculated by replacing the specific gravity RGB value with the RGB value for the concentration of creatinine among the test items.

Additionally, the absolute values of RGB values for colors that can be expressed in the pad area of each test item may be different.

Additionally, the types of RGB values that can be expressed in the pad area of each test item may be different.

Additionally, the subject of a urine test may be either a human or an animal.

Additionally, in order to correct the RGB value that can be recognized by the camera of the user terminal before step (a), the second RGB value can be calculated by photographing the color of the standard colorimetric table.

Additionally, in step (a), when photographing the urine test strip, an indicator may be provided to guide the position of the urine test strip.

Additionally, when photographing a urine test strip, if the surrounding illumination is below a preset setting, an alarm message requesting improvement of the photographing environment may be provided to the user.

Additionally, in step (a), if the image quality of the test image is below a preset value or the position of the urine test strip on the test image is above a preset error range, an alarm message requesting retaking may be provided to the user.

Additionally, after step (d), a comparison value for the test results of the specific user and another user may be calculated based on the error between the first RGB value of the specific user and the previously stored first RGB value of the other user.

The present invention can easily and conveniently perform a urine test on a test subject using a smart terminal.

In addition, even if each urine strip manufactured by each company contains the same test items, the colors that appear after the user puts urine on them all appear differently, so the health test results for one person may differ depending on which company's urine strip is used. It may appear differently. However, according to the present invention, there is an advantage that the same test results can always be obtained no matter which company's urine strip is used.

In addition, the accuracy of the test can be improved by correcting variables that may occur in the test results due to differences in the amount of urine discharged depending on the amount of water consumed, food with a diuretic effect, or intake of medicines.

Below, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. In order to clearly explain the present invention in the drawings, parts that are not related to the description are omitted, and similar parts are given similar reference numerals throughout the specification.

Throughout the specification, when a part is said to be "connected" to another part, this includes not only the case where it is "directly connected," but also the case where it is "electrically connected" with another element in between. . Additionally, when a part "includes" a certain component, this means that it may further include other components, rather than excluding other components, unless specifically stated to the contrary.

The following examples are detailed descriptions to aid understanding of the present invention and do not limit the scope of the present invention. Accordingly, inventions of the same scope and performing the same function as the present invention will also fall within the scope of rights of the present invention.

Figure 2 is a diagram showing the configuration of a system for performing a simple urine test according to an embodiment of the present invention.

Referring to FIG. 2, a system for performing a simple urine test may be comprised of a user terminal 100, a urine strip 200, and a server 300. In addition, although not shown in the drawing, the user terminal 100 and the server 300 are interconnected through a communication network.

According to one embodiment of the present invention, the user creates a test image by photographing a urine test strip stained with urine with the user terminal 100 for a urine test, and creates a test image corresponding to each test item area of the urine test strip in the test image. RGB values are extracted for each of the plurality of pad areas, and the first RGB value is generated for each inspection item.

At this time, the pad area is provided on the urine strip 200 and refers to an area where a reagent for testing each component contained in urine is applied. Therefore, each reagent has its own standard color, and when it reacts with urine, it changes color to different colors depending on the health status of the test subject. The first RGB value is an RGB value extracted for the color of this discolored pad area.

In addition, according to an embodiment of the present invention, a first ratio value is generated through the specific gravity RGB value and the first RGB value extracted from the pad area of specific gravity among the test items, and the specific gravity calculated through the standard colorimetric table. The second ratio value, which is the ratio between each inspection item, is compared with the first ratio value to calculate a numerical value for each inspection item.

Here, specific gravity is a test item that varies depending on the degree to which proteins are filtered by the glomeruli. 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 colors that can be expressed by the pad area corresponding to each test item for urine testing.

First, in the present invention, the reason why the first RGB value calculated from the urine test strip 200 is not directly compared with the RGB value calculated from the standard colorimetric table is because external factors such as the concentration of urine vary depending on the physical condition of the test subject. This is because the test results also vary depending on the condition of the urine. Therefore, the present invention divides the specific gravity RGB value extracted from the specific gravity with the first RGB value and the RGB value calculated from the standard colorimetric table to generate a ratio value and then performs the comparison.

In addition, the reason why the urine test is corrected based on specific gravity in the present invention is because most of the items of specific gravity are included in the urine test strips sold in the past.

As an additional example, the first ratio value and the second ratio value may be calculated by replacing the specific gravity RGB value with an RGB value for the concentration of creatinine among the test items instead of the specific gravity RGB value. In this case, the test item for creatinine is provided on the urine strip, so the RGB value for creatinine may be measured. Alternatively, the measured RGB value for creatinine may be received by the user terminal through a separate analysis device.

According to an embodiment of the present invention, the user terminal 100 may refer to a terminal that performs a urine test.

At this time, the user using the user terminal 100 may or may not be the subject of the urine test, and the test subject is either a human or an animal, and the subject of the test does not limit the scope of the present invention.

The user terminal 100 may generate a test image by photographing the urine test strip 200 using a camera provided therein.

Additionally, a first RGB value, which is an RGB value for each inspection item, is generated from the generated inspection image. It is characterized by comparing the ratio between the second RGB value and the specific gravity RGB value previously generated through a standard colorimetric table with the ratio of the first RGB value and the RGB value to specific gravity on the inspection image.

At this time, the application for performing a simple urine test may be an application built into the user terminal 100 or an application downloaded from an application distribution server and installed on the user terminal 100.

Additionally, the user terminal 100 refers to a communication terminal that can use a terminal application in a wired or wireless communication environment. Here, the user terminal 100 may be the user's portable terminal. In Figure 1, the user terminal 100 is shown as a smart phone, a type of portable terminal, but the spirit of the present invention is not limited thereto, and as described above, there is no limitation to a terminal capable of mounting a terminal application. It can be borrowed.

To explain this in more detail, user terminal 100 may include any type of handheld computing device (e.g., PDA, email client, etc.), a cell phone, or any other type of computing or communication platform. However, the present invention is not limited to this.

In one embodiment of the present invention, the urine test strip 200 is coated with test reagents of various colors on one side, and when urine is stained, the color of the test reagent changes to various colors depending on the user's health, thereby improving the user's health. It can be a device to inform you of what the status is.

In the conventional case, the urine test strip 200 has the shape of a stick, but if the color of the urine test strip 200 changes depending on the test item and the color of the reagent reacts with urine, the shape does not limit the scope of the invention. .

In one embodiment of the present invention, the server 300 may perform a urine test on behalf of the user terminal 100.

For example, when receiving an inspection image from the user terminal 100, the first RGB value is extracted from the received inspection image, and the ratio RGB value and contrast are compared with the second RGB value previously generated through a standard colorimetric table as described above. It is characterized by:

Therefore, in an optional embodiment, the server 300 may be excluded from the system of the present invention, and the invention may be implemented only through the user terminal 100 and the urine test strap 200.

Meanwhile, the communication network serves to connect the server 300 and the user terminal 100. In other words, the communication network refers to 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. Communication networks include, for example, wired networks such as LANs (Local Area Networks), WANs (Wide Area Networks), MANs (Metropolitan Area Networks), and ISDNs (Integrated Service Digital Networks), or wireless networks such as wireless LANs, CDMA, Bluetooth, and satellite communications. may encompass, but the scope of the present invention is not limited thereto.

Figure 3 is a diagram showing the configuration of a user terminal according to an embodiment of the present invention.

Referring to Figure 3, the user terminal 100 according to an embodiment of the present invention includes a communication module 110, a memory 120, a processor 130, a database 140, a color extraction module 150, and a sample inspection module. Includes (160).

In detail, the communication module 110 provides a communication interface necessary to provide transmission and reception signals between the user terminal 100 and the server 300 in the form of packet data in conjunction with a communication network. Furthermore, the communication module 110 may receive a data request from the server 300 and transmit data in response.

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

As a further embodiment, if the server 300 is excluded from the system implementing the present invention, the user terminal 100 does not need to be equipped with the communication module 110.

The memory 120 records a program for performing a simple urine test. Additionally, it performs a function of temporarily or permanently storing 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.

The processor 130 is a type of central processing device that controls the entire process for performing a simple urine test. Each step performed by the processor 130 will be described later with reference to FIG. 4.

Here, the processor 130 may include all types of devices that can process data, such as a processor. Here, 'processor' may mean, for example, a data processing device built into hardware that has a physically structured circuit to perform a function expressed by code or instructions included in a program. Examples of data processing devices built into hardware include a microprocessor, central processing unit (CPU), processor core, multiprocessor, and application-specific integrated (ASIC). circuit) and 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 urine tests, second RGB values corresponding to pre-stored standard colorimetric tables, test results, etc.

In addition, so that the camera of the user terminal 100 can correctly recognize the color of the urine test strip 200, a standard colorimetric table is taken in advance to perform color correction, and the settings for the correction results are stored in a database ( 140).

Although not shown in FIG. 2, some of the second RGB values and test results corresponding to the test image taken for the urine test and the previously stored standard colorimetric table are stored in a database (not shown) physically or conceptually separated from the database 140. city) can be saved.

The color extraction module 150 may be a module for extracting RGB values from colors that can be expressed in the inspection image or the pad area included in the standard colorimetric table.

Therefore, the color extraction module 150 extracts RGB values from an inspection image captured from a camera module provided in the user terminal 100 or an inspection image received from outside, or extracts RGB values from a previously input standard colorimetric table. You can.

The sample inspection module 160 may be a module that calculates a numerical value for each inspection item by comparing the first RGB value extracted from the inspection image and the second RGB value extracted from the standard colorimetric table after correcting them with the specific gravity RGB value. .

Figure 4 is an operational flowchart showing a method for performing a simple urine test according to an embodiment of the present invention.

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

Before starting the urine test, the standard colorimetric table and the second RGB value may be calculated and stored in advance.

Additionally, when performing imaging of the urine test strip 200, the user terminal 100 may be provided with an indicator to guide the position of the urine test strip 200. By placing the urine test strip 200 in a position guided by the indicator and taking pictures, the user can create a test image that facilitates the extraction of test items and RGB values.

However, when photographing the urine test strip 200, if the surrounding illumination is below a preset setting, 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 the preset value or the position of the urine test strip 200 on the test image is above the preset error range, the user terminal 100 may provide the user with an alarm message requesting filming. It will exist.

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

In an additional embodiment, the step (S310) of receiving the inspection image or the first RGB value from another user terminal 100 or the server 300 and performing photography may be omitted.

Afterwards, the user terminal 100 generates a first ratio value through the specific gravity RGB value and the first RGB value extracted from the pad area of specific gravity among the test items, and each of the specific gravity values calculated through the standard colorimetric table. A value for each test item is calculated by comparing the second ratio value, which is the ratio between test items, with the first ratio value (S330).

At this time, the second ratio value may refer to the ratio between the colors of the pad area of the test item compared to the color that can be expressed in the pad area of the specific gravity, based on the RGB value extracted from the standard colorimetric table as described above. there is.

In other words, the second RGB values for all colors that can be expressed by the pad area of each test item are calculated according to the user's multiple health conditions, and all the colors that the pad area of each second RGB value and specification can express are calculated. The ratio between RGB values for color is calculated. In addition, the task 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 margin range of a preset 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 a numerical value for each inspection item is calculated.

After step S330, a step of determining the health status of the test subject for each test item based on the values calculated in response to the test item and providing the test result to the user may be further included.

At this time, based on the value calculated as a test result, the user terminal 100 displays the result of whether the health status of the test subject is normal/abnormal through a simple symbol such as O/X or a message such as “normal”/”abnormal.” By providing it in this format, confusion caused by providing too much information to non-experts can be prevented.

In addition, in an additional embodiment, when an abnormal determination of health is displayed, the user terminal 100 requests the user to re-test along with a message recognizing that the test may be uncertain (e.g., a suspected abnormality message, etc.). A message can be provided.

In an optional embodiment, a comparison value for the test results of a specific user and another user may be calculated based on an error between the first RGB value of a specific user and the previously stored first RGB value of another user.

For example, by contrasting the RGB value of ascorbic acid extracted from the test image of person A with the RGB value of ascorbic acid extracted from the test image of person B, it is possible to compare which person's ascorbic acid level is lower. There will be.

Figure 5 may be an example of a table for comparing ratio values based on RGB values, according to an embodiment of the present invention. The RGB value consists of R, G, and B values each having separate numerical values, but the table in Figure 5 shows that the RGB value is based on one average value or one representative value of the R value, G value, and B value. It was written assuming that it was composed.

Referring to FIG. 5, the specific gravity pad area 510, ascorbic acid pad area 520, and ratio table 530 can be confirmed in the drawing.

The specific gravity pad area 510 and the ascorbic acid pad area 520 shown in the drawing may be included in a standard colorimetric table and become a collection of tables that can be displayed in response to the urine of the test subject.

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

The ratio table 530 represents the second ratio value compared to the specific gravity that ascorbic acid can have.

For example, the first column can be the four lattices that ascorbic acid can have, and the second column can be the RGB values (second RGB values) of the standard colors of each lattice. In the example, these are assumed to be 10, 20, 30, and 40, respectively.

In fact, the reagent of the urine test strip 200 does not perfectly match the color of the ascorbic acid pad area 520 of the standard colorimetric table, and the color of a section with continuous values may be expressed. Therefore, like the third column, the actual second RGB value has a preset margin.

Additionally, in FIG. 5, the specific gravity pad area 510 is composed of seven grids, and the difference in specific gravity values is assumed to be 0.005. Accordingly, when the specific gravity is divided by the RGB value for each grid, the grid value of each ascorbic acid is displayed in the 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 state is determined to be the user's health state.

At this time, when the margin value increases, the range of each second ratio value in the ratio table widens, and a section in which the ranges of different second ratio values overlap may occur. If the first ratio value belongs to the overlapping section, the user terminal 100 may further include a step of performing correction on the overlapping result value after the above-described step (S330).

For example, the second ratio value shown in FIG. 5 was calculated based on specific gravity, but through comparison with other second ratio values calculated using other components including creatinine in addition to specific gravity, the first ratio value was calculated as above. Correction can be performed so that it falls within the non-overlapping section of . On the other hand, the inspection results may be corrected by calculating a plurality of second ratio values corresponding to each of the R value, G value, and B value and comparing them with the first ratio value. This is just an example, and correction may be accomplished in other ways as well.

Figure 5 shown in the present invention is only an example for explaining the present invention, and the numbers or colors described in the drawing do not limit the scope of the present invention.

One embodiment of the present invention may also be implemented in the form of a recording medium containing instructions executable by a computer, such as program modules executed by a computer. Computer-readable media can be any available media that can be accessed by a computer and includes both volatile and non-volatile media, removable and non-removable media.
