Accurate positioning test paper for urine testing

Abstract

The invention discloses an accurate positioning test paper for urine testing. The test paper includes a test piece and a white long-strip thin substrate, wherein the white long-strip thin substrate includes an integrally-formed rectangular plate portion and a handle portion, the test piece is disposed on the rectangular plate portion, the test piece is provided with multiple equally-spaced small test papers, the rectangular plate portion is located outside each small test paper and close to the small test paper and is provided with a black outer frame, a middle portion of the test piece is provided with an insertion prompt line in the width direction, a middle and lower edge of the test piece is provided with an arrow prompt icon in the length direction, a mark of this face up is arrangedbelow the arrow prompt icon, and a round transition is arranged at a corner of the test piece. The test paper is positioned accurately, and the detection result has high precision.

Description

technical field [0001] The invention relates to the medical field, in particular to a test paper block with accurate positioning for urine detection. Background technique [0002] At present, with the improvement of living standards and changes in lifestyles, the incidence of chronic diseases continues to increase, and the number of sick people is also increasing. Early screening and daily management of diseases have become a major problem in family health and public health; through Adding reagent blocks to detect multiple indicators of the body on the test strip can accurately determine the health of the human body, and has good clinical significance for the screening and monitoring of kidney function, liver function, inflammation, diabetes and many other diseases; [0003] Urine testing using test paper is a common method of medical testing, mainly by adding chemical reagents to the reagent block, chemically reacting with the secreted substances in the urine, resulting in ...

Problems solved by technology

[0007] (3) If the detection equipment is used to automatically detect the index, a longer slot is required, which is not conducive to the production, processing and use of the slot;

[0008] (4) Fewer prompts and poor user experience

[0010] (1) During each test, the position of the test paper block will always have a small change, and it is impossible to cut directly from the image by using a fixed position method, and it is very easy to crop inaccurately, resulting in incomplete test paper blocks, or Part of the test strip was introduced, which caused inaccurate test results;

[0011] (2) If the method of reducing the cropping frame is adopted, a large number of useful pixels on the test paper block will be wasted, and the calculation of the color average value will be inaccurate;

[0012] (3) If the color segmentation method is used in the image to obtain the test paper block, it is easy to be disturbed by the color cast and shadow of the camera and make mistakes;

[0013] (4) If the projection method is used to calculate the position of the test paper block, it is required that the test paper blocks in each row are aligned with high precision, and a slight offset will lead to incorrect algorithm results;

[0014] (5) When using an optical lens, especially a fisheye lens to take an image, there are generally different degrees of radial distortion; at this time, the method of realizing the positioning of the test paper block based on line detection, gradient projection, etc. in the image is invalid; and because the test paper It is difficult to predict the degree of distortion of each test paper block due to the small position change of the block
