Health-monitoring type intelligent closestool device and occult-blood detection method thereof

Abstract

The invention discloses a health-monitoring type intelligent closestool device and an occult-blood detection method thereof. The health-monitoring type intelligent closestool device comprises an occult-blood detection module. The health-monitoring type intelligent closestool device is characterized in that the occult-blood detection module is formed by combining a light source, an optical sensor and a first microcontroller. Excrement particles in aqueous excrement solution are washed away from a detection area by a water channel, a telescopic pipe extends out to be above the aqueous excrementsolution to carry out detection of occult-blood signals on the aqueous excrement solution, and backlight generated by a reflecting sheet irradiates towards the optical sensor, so that an over-the-airremote detection function for whether the occult-blood signals are contained in the excrement is realized, not only is the intensity of the backlight increased greatly, but also the scattering angle of the backlight can be effectively controlled, the optical sensor can receive and analyze the occult-blood signals more effectively, the signal-to-noise ratio is increased, the detection accuracy is greatly enhanced and the detection effect and efficiency are improved; the health-monitoring type intelligent closestool device is precise in whole design and simple and compact in structure, has high-efficiency detection function, is low in cost and is suitable for promotion and application.

Description

technical field [0001] The present invention relates to a detection device, in particular to a health monitoring smart toilet device and its detection method for occult blood, in particular to a device embedded in a smart toilet that can be extended to an aqueous solution of excrement by means of a photoelectric and mechanical structure A health monitoring smart toilet device and a blood occult detection method for automatically detecting whether an occult blood signal is contained in an 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 car...

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
