Abstract: A punch (1) with a shell (2) having an insertion opening (35) for material, which is to be punched, and punching pins (26) in connection with the opening as well as a lever mechanism (55), driven by an electric motor and designed to transmit punching force to the punching pins, which motor drives a gear reduction set with a small gear wheel (66) and a large driven gear wheel (64). An eccentric shaft (62) is eccentrically mounted in the latter wheel with concentric pins (63) in relation to the driven wheel, which concentric pins are mounted in the shell (2).

Abstract: The present invention relates to a diagnostic method used to indicate the migration of a medicament through the digestive apparatus and resorption during this migration, with the use of a negative MRI-contrast agent and a positive contract substance, introduced into gelatin capsules. The gelatin capsules are arranged as inner capsules in a common outer capsule, which is provided with barium sulphate in such an amount, relative to the specific gravity of the contents of the stomach, so that the capsule will be able to sink through the contents of the stomach and reach the small intestine without a substantial time-delay. The invention also relates to a diagnostic apparatus to carry out the diagnostic method.
