INGESTIBLE CAPSULES FOR SAMPLING INTESTINAL CONTENTS

摘要

One example device includes a capsule housing defining an interior cavity and a plurality of inlet ports; a piston disposed within the interior cavity and proximate to a first end of the capsule housing, the piston configured to seal an inner perimeter of the interior cavity to prevent movement of material past the piston; a biasing element positioned between within the interior cavity and between the piston and the first end of the cavity, the spring in at least a partially compressed state; an enteric material disposed within the interior cavity, the enteric material positioned between the piston and a second end of the cavity, the second end opposite the first end, the enteric material positioned to prevent movement of the piston by the biasing element towards the second end of the cavity.
