Concealed fecal occult blood detecting device and method

Abstract

The invention discloses a concealed fecal occult blood detecting device and method. The device comprises an occult blood detecting module for detecting whether a fecal aqueous solution in a toilet contains an occult blood signal, the occult blood detecting module is electrically connected to an intelligent toilet, and the intelligent toilet can be fixed on the toilet in an openable or closeable manner; the toilet is provided with a blow-off pipe, and the occult blood detecting module is disposed on the blow-off pipe. The occult blood detecting module formed by combining a light source, an optical sensor, a first microcontroller, and a DC-DC conversion module is used, the light source and the optical sensor are concealed in the blow-off pipe of the toilet, and an optical lens and a light guide tube guide the beam emitted by the light source to penetrate the fecal aqueous solution to generate penetrating light and irradiate the penetrating light onto the optical sensor, thereby realizingthe function of detecting whether the feces contains an occult blood signal; and the device is precision in overall design and simple and compact in structure, has an efficient detection function andlow cost, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a detection device, in particular to a built-in fecal occult blood detection device and a method thereof. Background technique [0002] According to the National Cancer Institute, colorectal cancer accounts for 8% of all cancer cases in the United States, ranking fourth in incidence and second in mortality. 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 ranking first in the world. Therefore, it is of worldwide significance to carry out the prevention and treatment of colorectal cancer in China. [0003] The initial symptom of colorectal cancer is fecal occult blood, and the initial symptom of bladder cancer and ureteral cancer is urine occult blood. Therefore, detection of fecal occult blood has become one of the important key technologies for disease prevention. The existing occult blood detection method adopts the immune method for occul...

AI Technical Summary

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

[0004] In addition, the Chinese invention 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 is necessary to add The fluorescent agent and the oxidizing agent are combined with the blood in the feces or urine in the toilet, and provide an excitation light to irradiate to judge whether there is fluorescence; on the other hand, for the general public, this method requires additional Steps, and will produce chemical consumables, inconvenient to use

[0005] The announcement number is 1998339728, and the Japanese patent with the publication date of December 22, 1998 discloses a stool component inspection device. The device and method mainly have the following problems: one is that it must have a stool collection program; the other is that it is necessary to add additional dilution liquid; third, must have a cleaning program

[0006] The U.S. patent with the notification number US7223604B1 discloses Methods and kits for the detection of erythrocytes. The patent mainly has the following problems: one is to use fluorescence to detect whether it contains occult blood signals; the other is to add a reacting solution, and this reacting solution contains a strong reducing agent with multiple substances; third, the processing before optical analysis is too complicated, and it is not suitable for ordinary people to operate at home

[0009] In addition, even if the existing toilet device is equipped with an occult blood detection module and has the function of occult blood detection, the detection position of the occult blood detection module is unreasonably set, for example, the occult blood detection module is not built in the toilet, so that the occult blood detection module is subject to many interferences , which greatly reduces the precision and accuracy of occult blood detection, and also brings a lot of inconvenience to the operation during the detection process
