Abstract

What is proposed is a swallowable capsule (1) configured to obtain fluid samples from the gastrointestinal (GI) tract of a subject comprising: an outer shell (2) surrounding an interior space (17); the outer shell (2) having at least one shell opening (3) serving as an inlet port that allows a fluid sample to enter into the swallowable capsule (1); a sampling chamber (21) which may hold one or more samples obtained from the GI tract; a piston (5) which is moveable in the interior space (17); a gas drive unit comprising a pressure generating device (10) that may build up pressure on one side of the piston (5) to propel the piston (5) in the interior space (17); the piston (5) having: a first seal portion (8) that closes the at least one shell opening (3) in a first position of the piston (5) thereby preventing fluid exterior to the swallowable capsule (1) from entering into the capsule (1); at least one piston opening (9) that may be arranged flush with the shell opening (3) in a second position of the piston (5) thereby allowing fluid exterior to the swallowable capsule (1) to enter into the capsule (1); a second seal portion (7) that closes the at least one shell opening (3) in a third position of the piston (5) thereby preventing fluid exterior to the swallowable capsule (1) from entering into the capsule (1); a microprocessor (12) configured to control the gas drive unit so as to consecutively propel the piston (5) in a forward direction (A) from the first position to the second position and to the third position. The gas drive unit eliminates the need for complex and space-occupying mechanics and is also very energy efficient.
