capsule has swallowed to obtain samples of gastric juice and / or intestinalthe canister containing chamber (18) for receiving a fluid having an orifice at (17) which is normally closed and isolated from the outside of the capsule by means of obstruction consistingin a body (21) which are in contact with the fluid properties of time present in the gastrointestinal tractthis causes the communication through the orifice (17) between the head and the outside of the capsule chamber (18) and a sample receiving fluid.in the room are closing means (9, 12)(14) normally held in position for movement by a mass (28) which fits the need of closing means together in such a way that they cannot move.so that the action of the closing means is neutralisee.this mass (28) is sensitive to the contact time of the gut fluid for the closing means (9, 12)14), closing the chamber (18) so that the sample is protected from contamination during the future through the remainder of the digestive tract.using a different mass (21, 28) which will dissolve in stomach acid, which will dissolve after contact with the whole intestine contained alkaline.the capsule can be used to obtain a sample of gastric juice and intestinal juice.an indicator of hcl, lactic acid, free or, alternatively, may be contained in the chamber (18) of the capsule, an indicator which reacts in the presence of hcl,and lactic acid in the sample to change the color of the sample, which makes it possible to see through a transparent part of the capsule wall.
