Catheter (10) provided with a flexible catheter tube (4) having a tip (3) of the catheter tube (4) to be introduced into the small intestines of humans or animals, the tip (3) being provided with an engagement body (1; 2) on which the peristalsis of viscera is able to engage in order to introduce the catheter (10). The engagement body is formed by at least one thickening (1; 2) provided with a bore which is in communication with the catheter tube (4). Preferably, two thickenings (1, 2) having a certain weight are attached, as a result of which an effective, as it were automatic, introduction of the catheter (10) is produced by a combination of gravity and engagement of gastric and intestinal peristalsis on the thickenings (1, 2). |
