Feces Formation and Defecation

Feces Formation and Defecation

After spending 3 to 10 hours in the large intestine, chyme loses a lot of water and becomes feces, the final product of digestion. Feces consist of undigested dietary fiber such as cellulose, mucus, sloughed-off epithelial cells, and microbes. The descending and sigmoid colon stores feces and uses haustral contractions to dry it out but retains enough water to give it a semi-solid texture.
The mass peristalsis then pushes the feces into the rectum, which stretches the rectal walls to activate...

Area of Science:

Gerontology and Biomedical Engineering
Artificial Intelligence in Healthcare

Background:

China's aging population includes a significant number of disabled elderly individuals requiring incontinence solutions.
Existing incontinence management methods like diapers and medication have limitations.

Purpose of the Study:

To develop an effective and convenient defecation pre-warning system for disabled elderly people.
To address the limitations of current incontinence management through technological innovation.

Main Methods:

Proposed a novel bowel sound acquisition system.
Developed a semi-supervised generative adversarial network (semi-supervised GAN) for defecation prediction using bowel sounds.
Established a network model to analyze bowel sounds for defecation tendency.

Main Results:

The proposed method accurately classified bowel sounds indicating a defecation tendency.
Achieved a classification accuracy of 94.4% for predicting defecation.

Conclusions:

The developed bowel sound acquisition system and AI-based defecation pre-warning method are effective.
This technology offers a promising, flexible, and convenient solution for incontinence management in the elderly population.
