Clinically, sputum with blood which is expectorated by a patient is directly expectorated without staying in the body, and the sputum is usually red and white, for example, sputum with blood filaments; some sputum is eluted after staying in the body and mixing, and the red sputum and the white sputum are mixed, so that blood in the sputum cannot be clearly distinguished; therefore, the color bar 41 may be provided in two for both cases. Wherein, one colorimetric strip is used for carrying out colorimetric treatment on sputum with blood which is not remained in the body of a patient and is directly expectorated; the other color comparison strip is used for carrying out color comparison on expectorated sputum with blood after staying and mixing in the body of a patient.
Medical personnel or patient can judge which color strip of use earlier and carry out the color comparison according to the state of sputum when using the sputum blood content detection means that this application embodiment provided, and then the contrast obtains the blood that contains of sputum and accounts for the ratio.
Specifically, both the colorimetric strips may include a plurality of colored colorimetric blocks, and the colorimetric blocks are sequentially arranged from light color to dark color.
The number of the colorimetric blocks can be set to be 10, the color of the colorimetric block can be prepared by blending red and white, wherein the proportion of red in the colorimetric block can be 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100% in sequence, the larger the proportion of red in the colorimetric block is, the darker the color of the colorimetric block is, the larger the proportion of blood in the sputum is.
Each color block is marked with a color number convenient for recording. Different color numbers are used for representing different colorimetric blocks, so that the color does not need to be described during recording, and the recording of the blood-containing ratio of the sputum is facilitated.
For example, the color numbers of the color patches of one of the color bars 41 can be set to 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, 1-9, 1-10 in sequence, and the larger the number after "-" in the color numbers, the larger the blood content ratio of the sputum is. The color numbers of the color blocks of the second colorimetric strip 42 can be set to be 2-1, 2-2, 2-3, 2-4, 2-5, 2-6, 2-7, 2-8, 2-9 and 2-10 in sequence, and the larger the number after "-" in the color numbers is, the larger the blood content ratio of the sputum is.
