Excrement occult blood detection device hidden in intelligent toilet and method thereof

Abstract

The invention discloses a high-effect excrement occult blood detection device hidden in a toilet. The detection device comprises an occult blood detection module. The detection method comprises the following steps: adopting the occult blood detection module formed by combining a light source, an optical sensor and a first microcontroller, stretching the occult blood detection module into an aqueous solution of excrements to perform occult blood signal detection on the aqueous solution of excrements, enabling light beams of a particular wavelength emitted by the light source to directly come into the excrement-containing aqueous solution in the toilet, and enabling backlight generated by a reflector plate to irradiate the optical sensor, so that the function of detecting whether the excrements contain the occult blood signal or not is realized. The intensity of the backlight is greatly improved, the scattering angle of the backlight can be effectively controlled, the optical sensor caneffectively receive and analyze the occult blood signal, the signal to noise ratio is improved, the detection accuracy is greatly enhanced, and the detection effect and efficiency are improved; and moreover, the device is precise in overall design and simple and compact in structure, has the high-efficiency detection function and low cost, and is suitable for popularization and application.

Description

technical field [0001] The present invention relates to a detection device, in particular to an excrement occult blood detection device built in an intelligent toilet and its method, in particular to a detection device built in an intelligent toilet that can be extended with photoelectric and mechanical structures Excrement occult blood detection device and method for automatically detecting whether the excrement aqueous solution contains occult blood signal in the excrement aqueous solution. Background technique [0002] According to the National Cancer Institute, in the United States, the incidence of colorectal cancer accounts for 8% of the total number of cancers, the incidence rate ranks fourth, and the mortality rate ranks second. In China, the incidence of colorectal cancer accounts for 18.6% of the world, and the death toll accounts for 20.1% of the world, both of which rank first in the world. Therefore, it is of worldwide significance to carry out the prevention a...

Problems solved by technology

The existing occult blood detection method adopts the immunoassay occult blood detection, which mainly has the following problems and disadvantages: First, the stool specimen must be collected by itself, and then sent back to the hospital to wait for the test results, which loses speed and convenience, and brings unnecessary waste to the test. Trouble; the second is that when collecting stool samples, only about 1 gram is collected. After arriving at the hospital, the hospital only uses about 6 mg of it for testing. Since occult blood is not evenly distributed in the stool, it is easy to fail to collect occult blood during the test. False negatives are produced, which reduces the detection efficiency and the detection effect is poor; the third is that the tumor or polyp itself is intermittent bleeding, not continuous bleeding, so it is also possible that the tumor or polyp may not be detected on the day or the day before the stool sample is collected. Bleeding, resulting in false negative test results, reducing the detection efficiency, and the detection effect is poor

In addition, the Chinese utility model patent with the announcement number CN104254621A and published on December 31, 2014 discloses a device and method for remotely measuring blood in human feces and urine. The device and method mainly have the following problems: On the one hand, it must Add fluorescent agent and oxidant to the toilet, combine with the blood in feces or urine, and provide an excitation light to irradiate to judge whether there is fluorescence; on the other hand, for the general public, this method needs to increase Extra steps, and produce chemical consumables, inconvenient to use
