Problems solved by technology

This kind of color chart, which is identified and produced by naked eyes, lacks uniform standards and objectivity
At the same time, the problem of color difference is not considered in the process of making the existing hematuria color comparison card, so the error is relatively large

Embodiment Construction

[0021] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments are used for detailed descriptions, as follows:

[0022] A kind of preparation method of hematuria color card is characterized in that, comprises the following steps:

[0023] Firstly, the whole blood is serially diluted, and the results of each ratio point after dilution are saved. In one preferred embodiment of the present invention, the specific ratio point results are: 100%, 64%, 32%, 16%, 8% %, 4%, 2%, 1%, 0.5%, 0.25%, 0.125%, 0%. This ratio is also the preferred ratio for hematuria comparison in clinical practice. Save the results of each ratio point after dilution, which is also convenient for further photography.

[0024] Then take pictures of the results of each ratio point of the multiple dilution and import them into the computer. After the photos of the results of each ratio point of the multiple ...

Abstract

The invention provides a production method of a blood urine colorimetric card. The production method comprises the following steps: (1) carrying out multiple proportion dilution on whole blood and storing each proportion point result after dilution; (2) photographing each proportion point result of the multiple proportion dilution and importing the results into a computer; after a picture of eachproportion point result of the multiple proportion dilution is imported into the computer, carrying out chromatic aberration checking on the picture of each proportion point result in the computer; (3) analyzing the picture of each proportion point result of the multiple proportion dilution through the computer to obtain a RGB (Red, Green and Blue) value corresponding to each proportion point result; (4) producing the colorimetric card by utilizing the RGB value corresponding to each proportion point result. The production method provided by the invention has the beneficial effects that 1, when the color of blood urine is judged, subjective judgment of medical personnel is reduced and the objectivity of judgment is enhanced; 2, a finished product is produced by adopting the RGB numerical values so that the consistency of the finished product is ensured; 3, the chromatic aberration checking is carried out in a production process so that errors are reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a color card for judging the color of hematuria. Background technique [0002] In the current medical process, the judgment of the color of hematuria basically depends on the subjective judgment of medical staff. For example, the making method of one of the hematuria color comparison cards in the prior art is: take pictures of the urine appearances of different colors, take 182 pictures in total, and then compare this group of pictures by doctors, head nurses and responsible nurses. Yes, screen out the most representative 8 photos, that is, the range from dark red to light red, divide them into 8 color levels in turn, and make them into a color comparison card. This kind of color chart, which is identified and produced by naked eyes, lacks uniform standards and objectivity. At the same time, the problem of color difference is not considered in the process of making the existing hematuria col...
