Description

소변분석용 스트립 및 이를 이용한 소변분석 방법Urine analysis strip and urine analysis method using the same
본 발명은 소변분석용 스트립에 관한 것으로, 더욱 상세하게는 휴대 단말기에 설치된 어플리케이션을 통해 소변으로 인한 스트립의 반응색을 분석하여 소변을 분석하는 소변분석용 스트립 및 소변분석 방법에 관한 것이다.The present invention relates to a urine analysis strip, and more particularly, to a urine analysis strip and urine analysis method for analyzing the urine by analyzing the reaction color of the strip due to the urine through an application installed in the portable terminal.
종래의 소변분석기는 개인이 휴대할 수 없는 크기의 기계로 구성되어 있고, 종합병원이나 중소 병원에서 환자의 진료 및 치료를 목적으로 개발된 장비로서 질병에 대한 징후를 파악하기 위하여 1차적으로 소변검사를 하고, 그 결과를 반영하여 2차적인 정밀 검사를 위한 임상병리검사 용도로 사용하는 것으로, 대부분이 중대형 장비로서 기기가격이 고가이며, 전문의가 아닌 일반인들의 접근이 허용되지 않고, 검사 후 결과를 알려면 며칠을 기다려야 하는 불편함이 따르기도 한다.Conventional urine analyzer is composed of a machine that can not be carried by the individual, and was developed for the purpose of treating and treating patients in general hospitals or small and medium hospitals. It is used as a clinical pathology test for the secondary overhaul by reflecting the results, and most of them are medium and large equipment, which is expensive, and is not allowed to be accessed by non-specialists. It may be inconvenient to wait a few days to find out.
이러한 문제점을 해결하기 위해, 소변분석용 스트립을 촬영하여 촬영결과를 분석하는 기술이 개발되었다. 즉, 소변분석용 스트립과 분석 기준이 되는 비색을 함께 촬영하여 촬영된 이미지를 비색 분석하는 방법이다. 하지만, 이러한 방법은 스트립과 비색이 별도로 분리되어 있어 동시 촬영 시 주변의 조명에 따른 영향으로 인해 분석결과가 부정확해지는 문제점이 발생할 수 있다.In order to solve this problem, a technique for analyzing a photographing result by taking a strip for urine analysis has been developed. That is, a method of colorimetric analysis of the photographed image by taking the urine analysis strip and the colorimetric that is the analysis standard. However, in this method, since the strip and the colorimetric are separated separately, there may be a problem that the analysis result is inaccurate due to the influence of ambient lighting during simultaneous shooting.
따라서, 본 발명에서는 분석 대상이 되는 스트립 내 색상과 분석 기준이 되는 비색을 인접하게 배치하고, 이외에 색상 고유의 색을 나타내는 표준 색상을 더 배치하여 비색 분석의 정확도를 향상시키고자 한다.Therefore, the present invention intends to improve the accuracy of colorimetric analysis by arranging the color in the strip to be analyzed and the colorimetric which is an analysis criterion adjacent to each other, and further arranging a standard color representing the color unique to the color.

Accordingly, a comparison operation between the discolored color of the reagent pad unit 120 and the colors of the first color unit 132b and the second color unit 134b may be performed more precisely.
또 다른 실시예로, 도 3b에 도시된 바와 같이, 비색부(130) 중 일부는 시약패드부(120)의 타단에만 배치될 수도 있다. 다시 말해, 특정 시약패드부(120)는 제1 비색부(132a)를 제외한 제2 비색부(134a)만 인접하여 배치될 수 있다.In another embodiment, as shown in FIG. 3B, some of the colorimetric portions 130 may be disposed only at the other end of the reagent pad portion 120. In other words, the specific reagent pad part 120 may be disposed adjacent to only the second colorimetric part 134a except for the first colorimetric part 132a.
예컨대, 스트립 몸체부(110) 상에서 1번째 위치에 배치된 시약패드부(120)는 타단에 제2 비색부(134a)만 인접하여 배치될 수 있다. 이에 따라, 상기 위치에 배치된 시약패드부(120)의 변색된 색상은 제2 비색부(134a)의 색상과 비교될 수 있다.For example, the reagent pad part 120 disposed at the first position on the strip body part 110 may be disposed adjacent to only the second colorimetric part 134a at the other end. Accordingly, the discolored color of the reagent pad unit 120 disposed at the position may be compared with the color of the second colorimetric unit 134a.

이격부(131)는 비색부(130)가 스트립 몸체부(110)의 양 측면으로부터 소정 간격만큼 이격됨에 따라 형성될 수 있다. 이에 따라, 스트립 제조 시에 발생할 수 있는 비색부(130)의 손실로 인해 시약패드부(120) 및 비색부(130) 간의 색상 비교에 대한 정확도가 감소하는 문제를 예방할 수 있다.The spaced portion 131 may be formed as the colorimetric portion 130 is spaced apart from both sides of the strip body portion 110 by a predetermined interval. Accordingly, it is possible to prevent the problem that the accuracy of the color comparison between the reagent pad portion 120 and the color portion 130 is reduced due to the loss of the color portion 130 that may occur when the strip is produced.
즉, 본 발명에서는 소정 크기의 스트립 몸체부(110) 상에 비색부(130)를 형성하기 위한 색상지를 인쇄하고, 시약패드부(120)를 형성하기 위한 패드를 롤링 후 커팅함으로써 독립된 복수의 스트립을 제조할 수 있는데, 소정 간격의 이격 공간 없이 일체로 연결된 색상지가 인돼된 스트립 몸체부(110)를 커팅하는 경우, 색상지의 일부가 뜯겨나가면서 미완성된 비색부(130)가 형성될 수 있다.That is, in the present invention, a plurality of independent strips are printed by printing color paper for forming the colorimetric portion 130 on the strip body portion 110 having a predetermined size, and cutting and rolling the pad for forming the reagent pad portion 120. In the case of cutting the strip body part 110 in which the color paper is integrally connected without a space of a predetermined interval, a part of the color paper may be torn off and an unfinished colorimetric part 130 may be formed.
이로 인해, 시약패드부(120) 및 비색부(130) 간의 정교한 색상 비교가 어려울 수 있으며, 이러한 문제를 사전에 방지하기 위해 본 발명의 소변분석용 스트립은 이격부(131)가 포함된 비색부(130)를 구현할 수 있다.Because of this, it may be difficult to compare the precise color between the reagent pad unit 120 and the colorimetric unit 130, in order to prevent such problems in advance the urine analysis strip of the present invention is a colorimetric unit including a spacer 131 130 may be implemented.

At least one or more colors, such as four, may be included in the first colorimetric portion 132a and the second colorimetric portion 134a. For example, the first colorimetric part 132a may include one color, and the second colorimetric part 134a may include the three colors to configure the colorimetric part 130.
여기서, 복수의 색상표 및 마커는 판의 길이 방향에 대해 수직 방향으로 롤링될 수 있다.Here, the plurality of color palettes and markers may be rolled in a direction perpendicular to the length direction of the plate.
이후에, 스트립 판을 기준으로 행 별로 나뉘어진 스트립을 스트립 판의 수평 방향으로 커팅함으로써, 완성된 스트립을 제조할 수 있다.Thereafter, the finished strip can be manufactured by cutting the strip divided into rows based on the strip plate in the horizontal direction of the strip plate.
이때, 비색부(130)에 해당하는 색상표지는 각 행 별로 동일한 열에 위치하게 되는 색상표지 사이에 소정 간격의 이격 공간이 마련되도록 인쇄될 수 있다. 이는, 스트립 판을 커팅 시 발생할 수 있는 색상표지의 손실로 인해 시약패드부(120) 및 비색부(130) 간의 색상 비교에 대한 정확도가 감소하는 문제를 예방할 수 있다. 다시 말해, 소정 간격의 이격 공간 없이 일체로 연결된 색상표지가 인돼된 스트립 판을 커팅하는 경우, 색상표지의 일부가 뜯겨나가면서 미완성된 비색부(130)가 형성될 수 있다.In this case, the color label corresponding to the colorimetric unit 130 may be printed such that a space of a predetermined interval is provided between the color labels positioned in the same column for each row. This may prevent a problem that the accuracy of the color comparison between the reagent pad unit 120 and the colorimetric unit 130 decreases due to the loss of the color label that may occur when cutting the strip plate. In other words, in the case of cutting a strip plate in which the color labels are integrally connected without a space of a predetermined interval, an unfinished color portion 130 may be formed while a portion of the color labels is torn off.
이로 인해, 시약패드부(120) 및 비색부(130) 간의 정교한 색상 비교가 어려울 수 있으며, 이러한 문제를 사전에 방지하기 위해 본 발명에서는 각 행 별로 이격 공간이 형성된 색상표지를 인쇄할 수 있다.Because of this, it may be difficult to precisely compare the color between the reagent pad unit 120 and the colorimetric unit 130. In order to prevent such a problem in advance, the present invention may print a color label formed with a space for each row.
도 6은 본 발명의 일 실시예에 따른 소변분석 방법을 설명하기 위해 도시한 흐름도이다. 후술하고자 하는 소변분석 방법에 있어서, 휴대 단말기의 카메라로 촬영된 영상을 분석하기 위한 어플리케이션을 활용하고자 한다.6 is a flowchart illustrating a urine analysis method according to an embodiment of the present invention. In the urine analysis method, which will be described later, an application for analyzing an image taken by a camera of a mobile terminal is used.
도 1 및 도 6을 참조하면, 단계(610)에서 휴대 단말기는 소변으로 인해 변색되는 시약패드부(120), 시약패드부(120)가 변색 가능한 복수의 색상을 포함하는 비색부(130) 및 어플리케이션의 실행에 의해 촬영하고자 하는 스트립을 인식하기 위한 기준점인 마커부(140)가 구비된 소변분석용 스트립을 촬영한다.1 and 6, in step 610, the mobile terminal includes a reagent pad unit 120 discolored due to urine, a colorimetric unit 130 including a plurality of colors of the reagent pad unit 120 that can be discolored, and The urine analysis strip is provided with a marker unit 140 which is a reference point for recognizing a strip to be photographed by executing an application.
이때, 어플리케이션의 실행에 따라 휴대 단말기의 화면에 표시되는 유효공간 내에 시약패드부(120), 비색부(130) 및 마커부(140)가 모두 포함되도록 위치를 조정해가며 스트립을 인식 및 자동 촬영할 수 있다.At this time, according to the execution of the application to adjust the position so that the reagent pad unit 120, the colorimetric unit 130 and the marker unit 140 are all included in the effective space displayed on the screen of the mobile terminal to recognize and automatically photograph the strip. Can be.
다음으로, 단계(620)에서 휴대 단말기는 마커부(140) 내 복수의 특징점 및 가상의 좌표계 내 좌표점 간의 정합관계에 대한 정합 알고리즘을 이용하여 촬영된 스트립에 관한 영상을 보정한다.Next, in operation 620, the mobile terminal corrects an image of the photographed strip by using a matching algorithm for a matching relationship between a plurality of feature points in the marker unit 140 and coordinate points in a virtual coordinate system.
단계(610)에 의해 촬영된 스트립에 관한 영상은 주변 촬영 환경에 따라 정확하게 인식되지 않을 수도 있다. 즉, 휴대 단말기 및 스트립 간의 높이, 각도 등의 차이로 인해 실제 스트립과 인식된 스트립 간의 인식오차가 발생하여, 소변분석에 따른 분석결과에 부정적인 영향을 미칠 수 있다.The image of the strip photographed by step 610 may not be correctly recognized according to the surrounding photographing environment. That is, due to the difference in height, angle, etc. between the mobile terminal and the strip, a recognition error may occur between the actual strip and the recognized strip, which may negatively affect the analysis result according to the urine analysis.
이러한 문제를 방지하고자, 본 실시예에서는 가상의 스트립 좌표계를 생성하고, 실제 스트립 상에서 설정된 특징점을 상기 좌표계로 모두 이동시키는 과정을 통해 스트립이 언제 어디서 촬영되는지 상관없이 촬영된 스트립의 위치 및 크기를 균일하게 만들 수 있다.In order to prevent such a problem, in the present embodiment, a virtual strip coordinate system is created, and the position and size of the photographed strip are uniformized regardless of when and where the strip is taken by moving all the feature points set on the actual strip to the coordinate system. You can make it.
이를 위해, 상기 정합 알고리즘 중 하나인 호모그래피(homography)를 이용할 수 있다. 구체적으로, 스트립에 포함된 제1 마커부(142) 및 제2 마커부(144)로부터 추출된 4개의 특징점 및 가상의 스트립 좌표계 내 좌표점 간의 정합관계에 대한 호모그래피를 이용하여 촬영된 스트립에 관한 영상을 보정할 수 있다.To this end, homography, which is one of the matching algorithms, may be used. Specifically, the strip photographed using homography for the matching relationship between the four feature points extracted from the first marker part 142 and the second marker part 144 included in the strip and the coordinate points in the virtual strip coordinate system. You can correct the related image.
호모그래피는 호모지니어스(homogeneous) 좌표계에서 평면물체의 2차원 이미지 변환관계를 설명할 수 있는 가장 일반적인 모델이며, 이 모델은 자유도가 8이기 때문에 호모그래피를 결정하기 위해서는 최소 4개의 매칭쌍이 필요하다.Homography is the most common model that can explain the two-dimensional image transformation relation of planar objects in homogeneous coordinate system. Since this model has 8 degrees of freedom, at least four matching pairs are required to determine homography.
이에 따라, 본 발명에서는 상기 어플리케이션을 통해 제1 마커부(142)를 구성하는 2개의 마커 내 각 코너점과 제2 마커부(144) 내 2개의 코너점을 가상의 스트립 좌표계 내 좌표점과 매칭쌍으로 입력하여 기하학적인 관계를 산출할 수 있고, 산출된 관계를 기반으로 영상을 보정할 수 있다.Accordingly, in the present invention, matching each corner point in the two markers constituting the first marker unit 142 and two corner points in the second marker unit 144 with the coordinate points in the virtual strip coordinate system through the application. The geometric relationship may be calculated by inputting the pair, and the image may be corrected based on the calculated relationship.
다음으로, 단계(630)에서 휴대 단말기는 보정된 영상으로부터 시약패드부(120)의 변색된 색상 및 비색부(130)의 색상을 비교하여 시약패드부(120)의 변색된 색상을 분석한다.Next, in step 630, the portable terminal analyzes the discolored color of the reagent pad unit 120 by comparing the discolored color of the reagent pad unit 120 with the color of the colorimetric unit 130 from the corrected image.
분석에 앞서, 특정 위치를 기반으로 시약패드부(120)의 영역 및 비색부(130)의 영역을 분리시켜 색상비교를 위한 영역을 확보할 수 있다.Prior to analysis, the area of the reagent pad unit 120 and the area of the colorimetric unit 130 may be separated based on a specific position to secure an area for color comparison.
이후에, 분리된 시약패드부(120)의 영역 및 비색부(130)의 영역의 중심에서 일정 크기의 윈도우인 ROI(Region of Interest)영역을 설정하여 시약패드부(120)의 변색된 색상 및 비색부(130)의 색상을 추출할 수 있다. 여기서, 추출되는 색상은 하기 수학식 1에 기초하여, ROI 영역 내의 색상에 대한 색상값의 평균값을 활용할 수 있다.Subsequently, the ROI (Region of Interest) region, which is a window of a predetermined size, is set at the center of the separated reagent pad unit 120 and the region of the colorimetric unit 130 to change the color of the reagent pad unit 120. The color of the colorimetric unit 130 may be extracted. Here, the extracted color may utilize an average value of color values for colors in the ROI region based on Equation 1 below.

The color located at the closest distance among the plurality of colors included in the colorimetric unit 130 around the reagent pad unit 120 may be matched with the discolored color of the reagent pad unit 120. For reference, Equation 2 regarding the distance is as follows.

도 12a 및 도 12b 는 종래의 소변분석용 스트립을 이용한 소변분석에 대한 실험 결과이고, 도 13a 및 도 13b 는 본 발명의 일 실시예에 따른 소변분석용 스트립을 이용한 소변분석에 대한 실험 결과이다.12A and 12B are experimental results for urine analysis using a conventional urine analysis strip, and FIGS. 13A and 13B are test results for urine analysis using a urine analysis strip according to an embodiment of the present invention.
종래의 소변분석용 스트립을 이용한 소변분석 및 본 발명의 일 실시예에 따른 소변분석에 사용된 소변분석용 스트립은 모두 10개의 시약패드부를 구비하고, 각 시약패드부의 양단에 복수의 색상을 포함하는 비색부를 구비한다.Urine analysis using a conventional urine analysis strip and the urine analysis strips used in the urine analysis according to an embodiment of the present invention are all provided with 10 reagent pads, each of the reagent pads includes a plurality of colors A colorimetric part is provided.
이때, 10개의 시약패드부 중 스트립의 일단에서 타단 순으로의 배치 기준에 따라, 제1 시약패드부의 변색된 색상은 비색부에 포함된 3가지의 색상과 비교하였고, 제2 시약패드부의 변색된 색상은 비색부에 포함된 5가지의 색상과 비교하였고, 제3 시약패드부의 변색된 색상은 비색부에 포함된 6가지의 색상과 비교하였고, 제4 시약패드부의 변색된 색상은 비색부에 포함된 4가지의 색상과 비교하였고, 제5 시약패드부의 변색된 색상은 비색부에 포함된 4가지의 색상과 비교하였고, 제6 시약패드부의 변색된 색상은 비색부에 포함된 6가지의 색상과 비교하였고, 제7 시약패드부의 변색된 색상은 비색부에 포함된 6가지의 색상과 비교하였고, 제8 시약패드부의 변색된 색상은 비색부에 포함된 5가지의 색상과 비교하였고, 제9 시약패드부의 변색된 색상은 비색부에 포함된 4가지의 색상과 비교하였고, 제10 시약패드부의 변색된 색상은 비색부에 포함된 5가지의 색상과 비교하였다.At this time, the discolored color of the first reagent pad portion was compared with three colors included in the colorimetric portion according to the arrangement criteria from one end of the strip to the other end of the ten reagent pad portions. The color was compared with the five colors included in the colorimetric part, and the discolored color of the third reagent pad part was compared with the six colors included in the colorimetric part, and the discolored color of the fourth reagent pad part was included in the colorimetric part. The discolored color of the fifth reagent pad portion was compared with the four colors included in the colorimetric portion, and the discolored color of the sixth reagent pad portion was compared with the six colors included in the colorimetric portion. The discolored color of the seventh reagent pad portion was compared with six colors included in the colorimetric portion, and the discolored color of the eighth reagent pad portion was compared with the five colors included in the colorimetric portion, and the ninth reagent. The discolored color of the pad part is colorless It was compared to the four colors that are included in the tenth discolored color reagent pad portion was compared with the color of the five contained in the colorimetric section.
종래의 소변분석용 스트립 및 본 발명의 일 실시예에 따른 소변분석용 스트립은 모두 동일한 형태의 시약패드부 및 비색부를 구비하되, 기준 색상정보를 표시하는 표시부가 포함된 마커부의 구비여부에 있어 차이가 있다.The conventional urine analysis strip and the urine analysis strip according to an embodiment of the present invention are all provided with a reagent pad portion and a colorimetric portion of the same type, the difference in whether there is a marker portion including a display unit for displaying the reference color information There is.
즉, 종래의 소변분석용 스트립을 이용한 소변분석의 경우, 스트립 상의 양단에 기준 색상정보를 표시하는 마커부가 구비되어 있지 않은 스트립을 이용하였고, 본 발명의 일 실시예에 따른 소변분석용 스트립을 이용한 소변분석의 경우, 스트립 상의 양단에 기준 색상정보를 표시하는 마커부가 구비된 스트립을 이용하였다.That is, in the conventional urine analysis using a strip for urine analysis, a strip having no marker part displaying reference color information at both ends of the strip was used, and the strip for urine analysis according to an embodiment of the present invention was used. In the case of urine analysis, a strip having a marker part displaying reference color information at both ends of the strip was used.
또한, 시약패드부의 변색된 색상에 대한 색상값 및 비색부의 색상에 대한 색상값 간의 좌표값 차이를 나타내는 거리(Distance)에 기초하여, 시약패드부의 색상 및 비색부의 색상 간의 색상 비교를 수행하였다. 참고로, 거리(Distance)에 기초하여 산출된 좌표값 차이가 작을수록 유사한 색으로 판단할 수 있다.Further, a color comparison between the color of the reagent pad part and the color of the non-color part was performed based on a distance indicating a difference between the color values for the discolored color of the reagent pad part and the color values for the color of the non-color part.
