Document Type and Number:
WIPO Patent Application WO/2018/133660
Kind Code:
A1
Abstract:
Disclosed are a gastrointestinal microorganism collection capsule and a collection system. The gastrointestinal microorganism collection capsule comprises one or more autonomous sample collecting and separating apparatuses. The collecting and separating apparatus comprises a capsule shell (6) and a capsule shell bottom cap (5), with at least one fluid flow channel (7) being formed on the capsule shell (6). A sample separating apparatus is provided in the capsule shell (6), and the sample separating apparatus comprises a piston (8) located on one side of the fluid flow channel (7), a spring (12) located between the piston (8) and the capsule shell (7) or the capsule shell bottom cap (5), and a limiting apparatus connected to the piston (8). The collection system comprises at least one gastrointestinal microorganism collection capsule and a capsule collection and detection apparatus. The gastrointestinal microorganism collection capsule can collect samples as far as the distal small intestine and proximal colon sections; samples of gastric fluid or intestinal fluid are automatically collected after the capsule reaches different positions in the gastrointestinal tract; after collecting samples of gastric fluid or intestinal fluid, the fluid flow channel (7) is completely closed, ensuring that microorganism samples are not contaminated; and after the capsule is excreted, the capsule collection and detection apparatus can notify a user to gather the capsule.
