It is about the harvester.

In general, intestinal micro-organisms have been confirmed to be related to diseases such as obesity and diabetes. In particular, in recent years, a high association with brain diseases such as depression, autism, and Alzheimer's has been confirmed, and it is highly variable by acquired factors such as sleep, diet, alcohol, caffeine, and exercise, and the human body in association with microbiome Studies to investigate the mechanism of action in the inner are being actively conducted.

In order to proceed with the study of these gut microorganisms, a method of collecting, purifying and analyzing feces samples is usually used. The stool sample is collected by using a collection kit consisting of a collection paper and a swab-shaped stick, receiving feces at the collection site, collecting it with a cotton swab, and sending it to an analysis institution.

The collection of stool samples using the above method is cumbersome because the patient or the user manually performs it, and the amount or condition of the stool is inconsistent, which prevents accurate analysis. There are disadvantages.

However, the toilet system of the registered patent is intended to measure the user's bowel movements for general biochemical values, etc., not for intestinal microbial DNA testing, and does not create a strict sterilization environment that is most required for intestinal microbial DNA testing. It is impossible to control microbial contamination from environmental factors and use it for highly sensitive intestinal microbial testing. In addition, the environment after the mutation is released from the body is different from the anaerobic environment in the intestine, and if the microorganism in the existing stool is directly biochemically processed and the DNA is not preserved, the microbial composition is greatly changed. Because the cycle of microorganism propagation is 20 minutes, if the stool is left without special treatment, it becomes a composition different from the existing microorganism composition even after a few minutes. For the specificity of intestinal microbial DNA testing, the sterilized stool is frozen at 20 degrees below zero and stored to suppress the growth of microorganisms, or stored in a cell lysis buffer (cell wall crushing solution) to store the DNA in the extracellular solution at room temperature or 4 degrees. How to store in. However, all of these methods bring a certain level of deformation to each microbial composition, causing bias in the data, and have the disadvantage that the maximum storage time is about 3 days at 4 degrees Celsius. In addition, the system of the registered patent is a structure in which the analysis is performed through the collected bowel movement after collecting the entire amount, and it is cumbersome to process it after collecting the bowel movement, and the configuration is in reality complicated to implement the structure, which increases manufacturing cost. However, it is impossible to prevent deformation or damage of collected bowel movements.

It is easy to automatically collect the user's bowel movement in a sterile environment, and prevent the damage of the collected bowel movement and deformation at the DNA level, and it is possible to store it for a long period of time without a separate temperature control device. do.
