Semiautomatic health monitoring type intelligent toilet bowl device and occult blood detection method thereof

Abstract

The invention discloses a semiautomatic health monitoring type intelligent toilet bowl device and an occult blood detection method thereof. The semiautomatic health monitoring type intelligent toiletbowl device comprises an occult blood detection module. The occult blood detection module consisting of a light source and an optical sensor is used; the light source is arranged on a handheld light source pen; penetration light generated by penetrating light beams emitted out by the light source through an excreta water solution is guided and emitted to the optical sensor through a light guide tube; the detection function for detecting whether occult blood signals exist in the excreta or not is realized; the occult blood detection module is used for detecting whether blood exists in the excreta in the excreta water solution in the toilet bowl or not, and is not used for detecting whether cancer exists or not; in the detection process, no biochemical reagent needs to be added into the excreta water solution in the toilet bowl; the feces collection or urine collection from the excreta water solution in the toilet bowl is not needed, so that the occult blood detection used for the toiletbowel is very convenient; and the application is wide. The whole design of the device is precise; the structure is simple and compact; the effective detection function is realized; the cost is low; and the device is suitable for being popularized and used.

Description

technical field [0001] The invention relates to an intelligent toilet, in particular to a semi-automatic health monitoring intelligent toilet device and a detection method for occult blood. 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 and treatment of colorectal cancer in China. [0003] The early symptoms of colorectal cancer are fecal occult blood, and the early symptoms of bladder cancer and ureteral cancer are urine occult blood. Therefore, detection of fecal occult blood has become one of the key technologies for disease prevention. ...

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
