Abstract

A swallowable capsule for obtaining samples of gastric and/ or intestinal fluids, the capsule defining an inner fluid receiving chamber (18) having an inlet port (17) which is normally sealed off from the exterior of the capsule by way of a blocking means including a mass (21) the properties of which change upon contact with the suitable fluids present in the digestive tract, causing the means to communicate the inlet port (17) with the outside of the capsule allowing a sample of the fluid to be aspirated into the chamber (18). Located within the chamber is a closing means (9, 12, 14) normally maintained in a flow permitting position by a mass (28) which glues the necessary parts of the closing means together in such a way that the parts cannot move, so that the action of the closing means is neutralized. This mass (28) is responsive to contact with the suitable fluids of the alimentary canal to permit the closing means (9, 12, 14) to operate and seal off the chamber (18) so that the sample is secured from contamination during its further travel through the rest of the digestive tract. With the use of a different mass (21, 28), which will dissolve in gastric juice or which will not dissolve until after contact with the alkaline contents of the small intestine, the capsule may be used to collect a sample of gastric juice or intestinal juice, An indicator of free HCl, or alternatively of lactic acid, may be provided in the chamber (18) of the capsule, the indicator reacting to the presence of free HCl, or of lactic acid in the sample to change the color of the sample, which may be viewed through a transparent portion of the wall of the capsule.
