Problems solved by technology

In clinical practice, doctors usually only rely on the patient's chief complaint to understand the patient's medical history, and the patient's description of the amount and degree of hemoptysis is often vague; Give a qualitative description of the improvement or aggravation of the disease through longitudinal comparison, and it is impossible to quantify the blood content in the sputum coughed up by the patient each time

Embodiment 1

[0052] figure 1 It is one of the structural schematic diagrams of a tool for detecting blood content in sputum provided in the embodiment of the present application.

[0053] Such as figure 1 As shown, the tool for detecting blood content in sputum includes a base body 1 on which a height measurement area 2 , an area calculation area 3 and a colorimetric area 4 are arranged.

[0054] Wherein, the height measuring area 2 is provided with a height ruler 21, and a scale line is arranged on the height ruler 21. The minimum unit of measurement of the height ruler 21 can be millimeters or centimeters.

[0055] For example, 0cm, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm and 10cm are sequentially set on the height ruler 21 .

[0056] Since the sputum coughed up by a patient is usually collected on paper towels or waste containers in clinical practice, and the sputum is approximately round, the height ruler 21 can be used to measure the height of the sputum.

[0057] The area calcu...

Embodiment 2

[0074] figure 2 The second structural schematic diagram of a tool for detecting blood content in sputum provided by the embodiment of the present application.

[0075] Such as figure 2 As shown, on the basis of Embodiment 1, the blood content detection tool in sputum provided by this embodiment also includes a single-chip microcomputer (not shown in the figure) and a button group 22 of a height measurement area connected to the single-chip microcomputer, and an area calculation area The button group 32 of the color comparison area, the button group 42 and the touch screen 5. Wherein, the single-chip microcomputer can specifically adopt the single-chip microcomputer of MCS-51 series.

[0076] Each button in the button group 22 of the height measurement area is in one-to-one correspondence with each height value provided on the height gauge 21 . Each key in the key group 32 of the area calculation area is in one-to-one correspondence with the area of ​​the circle correspond...

Abstract

The invention provides a sputum blood content detection tool and a sputum blood content detection method, and the sputum blood content detection tool comprises a base body, and the base body is provided with a height measurement area, an area calculation area and a colorimetric area; a height gauge is arranged in the height measuring area and is used for measuring the height of the obtained sputum; the area calculation area is provided with a plurality of slits, and the area of a circle with the length of each slit as the diameter is marked corresponding to each slit; the obtained diameter ofthe sputum top surface is compared through the slit to obtain the area of the sputum top surface; obtaining the volume of the sputum according to the height of the sputum and the area of the sputum top surface; the colorimetric area is provided with a colorimetric strip, and the colorimetric strip comprises a plurality of colorimetric blocks with colors; the colorimetric blocks are sequentially arranged from light color to dark color; the colorimetric blocks are used for performing colorimetric treatment on sputum flushed out by the patient to obtain the blood-containing ratio of the sputum. According to the method, the blood content in the sputum can be quantified, so that a patient or a medical worker is helped to quantitatively describe the blood content in the sputum.

Description

technical field [0001] The application belongs to the technical field of medical auxiliary devices, and in particular relates to a detection tool and detection method for blood content in sputum. Background technique [0002] The descriptions of bloody sputum in the existing medical literature include bloody sputum, bloody sputum, and bloody sputum. In clinical practice, doctors usually only rely on the patient's chief complaint to understand the patient's medical history, and the patient's description of the amount and degree of hemoptysis is often vague; A qualitative description of the improvement or aggravation of the disease is given through longitudinal comparison, and the blood content in the sputum coughed up by the patient cannot be quantified each time. Contents of the invention [0003] In order to overcome the problems existing in the related technologies at least to a certain extent, the present application provides a detection tool and detection method for b...
