Description
본 발명은 반려동물용 소변검사 스트립에 관한 것으로, 더욱 상세하게는 사용자가 객관적이 색 비교가 가능한 반려동물용 소변검사 스트립에 관한 것이다.The present invention relates to a urine test strip for companion animals, and more particularly, to a urine test strip for companion animals in which a user can objectively compare colors.
개, 고양이 등의 반려동물과 생활을 함께하는 반려인의 증가추세에 따라 질병관리와 그 관리 및 처치 비용부담의 면밀함과 완화 방법의 제시가 시급한 실정이다.As the number of companions who live with companion animals such as dogs and cats increases, it is urgent to present disease management, meticulous management and treatment cost burden, and mitigation methods.
질병관리의 일환으로 반려동물의 건강상태를 손쉽게 확인 가능한 반려동물용 소변검사 스트립이 제안되었다.As part of disease management, a urine test strip for companion animals that can easily check the health status of companion animals has been proposed.
이러한 소변검사 스트립을 이용한 반려동물 소변검사 방법은 비침습적이고 간편하게 반려동물의 건강상태를 확인 가능하지만 검사 결과를 분석하기 위해서는 색이 변한 시험지와 비색표지의 색 비교 과정이 사용자에게는 객관적인 색 비교가 쉽지 않은 문제점이 있다.The companion animal urine test method using these urine test strips is non-invasive and easy to check the health status of the companion animal, but in order to analyze the test results, the process of comparing the color of the colorimetric marker with the test strip that has changed color is easy for the user to compare the color objectively. There is a problem that is not.
즉, 반려동물용 소변검사 스트립은 소변과 스트립에 포함된 시약의 화학반응을 통해 10여 가지의 질병을 조기에 진단할 수 있는 방법으로 유용할 수 있지만 현재 사용된 제품들은 반려동물의 소변검사를 한 후 검사 판독을 위해서 색상이 변한 시약지와 비색표지의 색들을 비교해야 하는 과정이 필요하다. In other words, urine test strips for companion animals can be useful as a method for early diagnosis of 10 diseases through chemical reactions between urine and reagents contained in the strips, but currently used products do not perform urine tests on companion animals. After that, it is necessary to compare the colors of the colorimetric label with the reagent paper whose color has changed for inspection reading.
이러한 소변검사 스트립의 판독 문제를 해결하기 위해 스마트폰을 이용한 판독방법이 제안되었다.In order to solve the reading problem of these urine test strips, a reading method using a smartphone has been proposed.
스마트폰을 이용한 반려동물의 소변검사 스트립 판독은 스마트폰 카메라를 이용하여 소변검사 스트립을 촬영한 후 영상내의 시약지 색상과 기저장된 비색표와의 비교를 통하여 판독한다.In order to read the urine test strip of a companion animal using a smartphone, the urine test strip is photographed using a smartphone camera and then read through comparison between the color of the reagent paper in the image and a pre-stored colorimetric table.
그러나, 스마트폰 기반으로 개발된 반려동물 소변검사 스트립 판독 방법들은 검사단계의 편리성과 휴대성 그리고 검사결과의 정확성을 동시에 만족하지 못하고 있으며 조명 환경 변화에 취약한 모습을 보이고 있다.However, companion animal urine test strip reading methods developed based on smartphones do not satisfy the convenience and portability of the test step and the accuracy of test results at the same time, and are vulnerable to changes in the lighting environment.
특히, 도 1과 같이 스마트폰 카메라를 통해 영상을 획득할 때 주변 조명환경(화이트 밸런스, WB)에 따라 색 좌표가 이동된 색을 얻게 되어 정확한 색상 비교를 할 수 없는 것이 주된 문제점이다.In particular, when acquiring an image through a smartphone camera as shown in FIG. 1, the main problem is that accurate color comparison cannot be performed because a color with color coordinates shifted according to the ambient lighting environment (white balance, WB) is obtained.
그리고, 특정 조명환경에서만 색상 보정이 잘되는 문제와 특정 색상에 대해서는 색상 판도 정확도가 떨어지는 문제점을 가지고 있다.In addition, there are problems in that color correction is performed well only in a specific lighting environment and color matching accuracy is low for a specific color.
따라서, 시험지와 비색표지의 객관적인 색 비교가 가능한 개선된 형태이 반려동물용 소변검사 스트립의 개발이 요구되고 있는 실정이다.Therefore, there is a demand for development of an improved type of urine test strip for companion animals that can objectively compare the color of the test strip and the colorimetric label.
본 발명은 전술한 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 반려동물의 소변과 반응하는 시약지 주변에 관련된 비색표를 배치시켜 검사 결과를 정확하게 판독 가능한 반려동물용 소변검사 스트립을 제공하는 데 있다.The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to arrange a colorimetric table related to the reagent paper that reacts with the urine of a companion animal to accurately read the test result. to provide strips.
상기와 같은 목적을 달성하기 위한 본 발명의 반려동물용 소변검사 스트립은, 원형의 비색표가 구비된 색지표; 반려동물의 소변과 반응하여 색상이 변하는 시험지가 구비된 시약지;를 포함하되, 상기 비색표 중앙으로 관통공이 형성되며 시험지는 관통공에 배치된 것을 특징으로 한다.The urine test strip for companion animals of the present invention for achieving the above object includes a color indicator provided with a circular colorimetric indicator; Reagent paper equipped with a test paper whose color changes in response to urine of a companion animal; including, but characterized in that a through hole is formed in the center of the colorimetric table and the test paper is disposed in the through hole.
또한, 상기 비색표는 상기 색지표의 길이 방향을 따라 둘 이상 배치되며, 상기 시험지도 시약지의 길이 방향을 따라 둘 이상 배치 것을 특징으로 한다.In addition, two or more colorimetric tables are disposed along the longitudinal direction of the color index, and two or more test maps are disposed along the longitudinal direction of the reagent paper.

It is an exemplary view showing a colorimetric table of a urine test strip for companion animals according to the present invention, and FIG. 5 is an exemplary view showing reagent sheets of a urine test strip for companion animals according to the present invention.
도 2 내지 도 5에 도시한 바와 같이, 본 발명에 따른 소변검사 스트립은, 원형의 비색표가 구비된 색지표와, 반려동물의 소변과 반응하여 색상이 변하는 시험지(기판)가 구비된 시약지로 구성된다.As shown in FIGS. 2 to 5, the urine test strip according to the present invention is a reagent paper equipped with a color indicator having a circular colorimetric indicator and a test strip (substrate) whose color changes in response to urine of a companion animal. It consists of
이때, 상기 비색표 중앙으로 관통공이 형성되며 시험지는 관통공에 배치된다.At this time, a through hole is formed in the center of the colorimetric table, and a test paper is placed in the through hole.
이에 따라, 기존 제품의 문제점인 주변 환경(조명)과 측정시마다 변화하는 색상값에 대한 편차를 최소화하는 디자인으로 설계된다. 즉, 비색표를 원형으로 디자인하여 소변과 반응하는 시약지 주변에 관련된 비색표를 인접시킨 형태의 새로운 소변검사 스트립을 제안했다.Accordingly, it is designed with a design that minimizes the deviation of the surrounding environment (lighting), which is a problem of existing products, and the color values that change at each measurement. In other words, we proposed a new urine test strip in which the colorimetric table was designed in a circular shape and the related colorimetric table was adjacent to the reagent paper that reacts with urine.
결국, 소변 진단 시약지와 진단 스트립 측정 판정 색지표가 서로 인접해있으므로 조명환경에 상관없이 정확한 검사결과 판독 가능하다.As a result, since the urine diagnostic reagent paper and the diagnostic strip measurement judgment color indicator are adjacent to each other, accurate test results can be read regardless of the lighting environment.
또한, 상기 비색표는 상기 색지표의 길이 방향을 따라 둘 이상 배치되며, 상기 시험지도 시약지의 길이 방향을 따라 둘 이상 배치된다.In addition, two or more colorimetric tables are disposed along the length direction of the color index, and two or more test maps are disposed along the length direction of the reagent paper.
그리고, 상기 관통공으로 시험지가 배치되도록 상기 색지표로 시약지가 삽입되도록 구성된다. 관통공으로 시험지가 배치되는 다양한 구조로 변형가능하다.And, the reagent paper is inserted into the color indicator so that the test paper is disposed in the through hole. It can be deformed into various structures in which test strips are placed through the through hole.
한편, 상기 시약지는 시험지(기판)는 PET 또는 PLA로 사용되며, 각각의 검사를 위하여 시험지 조건을 시약과 용량을 기본 formulation으로 사용하며 성분 조절 등을 통하여 최적화 하였다. 각 용액을 혼합하여 상온에서 건조 시킨 후 Backbone card에 붙인 후 Cutter기를 사용하여 스트립 형태로 절단한다.On the other hand, the test strip (substrate) is used as PET or PLA, and the test strip conditions for each test are optimized by using reagents and doses as basic formulations and adjusting components. After mixing each solution and drying it at room temperature, attach it to the backbone card and cut it into strips using a cutter.
도 4에 도시한 바와 같이, 10종 종류의 검사항목별 표준용액을 희석하여 양성 표준물질을 만들고 제작한 스트립을 테스트하여 각 각의 색상에 맞는 pantone의 색상 번호를 조사하고 비색표를 제작한다.As shown in FIG. 4, the standard solution for each of 10 types of test items is diluted to make a positive standard material, and the prepared strip is tested to investigate the color number of pantone for each color and prepare a colorimetric table.
도 5에 도시한 바와 같이, 10종 반려동물 검사 스트립은 각각 제작한 10종 시약지를 절단하여 제작한다. 10종 시약지에 대한 반응은 용액을 시약지에 침전 및 건조 작업 후 PET 또는 PLA 시험지(기판)에 3~5mm 간격으로 스트립 형태로 절단하여 제작한다.As shown in FIG. 5, 10 types of companion animal test strips are manufactured by cutting 10 types of reagent paper respectively. The reaction for 10 types of reagent paper is prepared by precipitating and drying the solution on the reagent paper, and then cutting into strips at 3-5 mm intervals on PET or PLA test paper (substrate).
도 3에 도시한 바와 같이, 반려동물 진단앱의 화면은 검사 시작화면과 반려동물 기존 검사 결과의 변화추이를 확인할 수 있는 메뉴, 프로그램의 사용자 매뉴얼 연결 메뉴로 구성하며, 사용자 매뉴얼 구성은 웹 서버에서 HTML로 구성한다.As shown in FIG. 3, the screen of the companion animal diagnosis app consists of a test start screen, a menu that can check the trend of changes in the companion animal's existing test results, and a user manual connection menu of the program. The user manual is configured on the web server. Constructed in HTML.
또한, 검사 시작 화면은 10종 검사 스트립의 촬영 시작 버튼과 스트립의 위치를 잡기위한 UI로 구성하고 결과화면은 음/양성 결과를 나타내도록 구성하며 검사결과에 대한 각각의 그래프로 표현하도록 구성한다.In addition, the test start screen is composed of a shooting start button for 10 types of test strips and a UI for locating the strips, and the result screen is composed to display negative/positive results and to express each test result as a graph.
스마트폰을 이용하여 소변검사 스트립을 촬영한 후 촬영된 영상 내에서 검정색선과 스트립 배경(흰색)의 픽셀 값을 추출하여 표 2의 수식을 이용하여 영상내의 색 값을 보정한다.After photographing the urine test strip using a smartphone, the pixel values of the black line and the strip background (white) are extracted from the photographed image, and the color value in the image is corrected using the formula in Table 2.
또한, RGB 색 공간에서는 비색의 단계에서 따른 색 공간에서의 분포를 분석하기 어렵기 때문에 RGB색 공간이 아닌 HSV 색 공간을 이용하여 색 공간에서 색의 분포를 분석한다. 비색이 1 ---> 2 ---> 3 ---> 4단계로 이동할수록 Hue와 Saturation이 동시에 변하고 있지만 그 색 변화가 예측 가능함을 확인할 수 있는데 비색 사이의 관계식을 이용한다.In addition, since it is difficult to analyze the color distribution in the color space in the RGB color space, the color distribution in the color space is analyzed using the HSV color space rather than the RGB color space. As the colorimetry moves from 1 ---> 2 ---> 3 ---> 4 steps, Hue and Saturation are changing at the same time, but it can be confirmed that the color change is predictable. The relational expression between colorimetry is used.
비색의 변화에 따른 Hue 값과 Saturation 값의 변화Changes in Hue and Saturation values according to colorimetric changes
또한, 가변 조명 환경을 위한 알고리즘 개발 및 최적화를 수행한다.In addition, it develops and optimizes algorithms for variable lighting environments.
즉, 소변검사 스트립의 색상 판별에 유리한 HSV와 CMY 색상 모델을 이용하여 Lab색상 모델을 통한 전처리 조명 보정한다.That is, preprocessing lighting is corrected through the Lab color model using the HSV and CMY color models, which are advantageous for color discrimination of the urine test strip.
표 4는 국부적인 조명 변화를 표시한 것으로, RGB이미지를 Lab이미지로 변환하여 밝기 성분인 Lightness채널에 미디언 필터링(Median Filtering)을 통해 조명 이미지를 획득하고 이를 역 변환하여 역 조명이미지를 획득한다.Table 4 shows the local lighting change, converting the RGB image into a Lab image, obtaining a lighting image through median filtering on the Lightness channel, which is a brightness component, and inversely converting it to obtain an inverse lighting image. .
이상, 본 발명의 바람직한 실시 예에 대하여 상세히 설명하였으나, 본 발명의 기술적 범위는 전술한 실시 예에 한정되지 않고 특허청구범위에 의하여 해석되어야 할 것이다. 이때, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 고려해야 할 것이다.In the above, the preferred embodiments of the present invention have been described in detail, but the technical scope of the present invention is not limited to the above-described embodiments and should be interpreted according to the claims. At this time, those skilled in the art should consider that many modifications and variations are possible without departing from the scope of the present invention.
