The invention relates to a device for fixing a hose segment of a hose line in the form of a loop for a device with which a liquid is delivered to a patient or removed from the patient via a hose line, in particular for monitoring the vascular access in an extracorporeal blood treatment. In addition, the invention relates to a hose line (7) for delivering a liquid to a patient or removing a liquid from a patient, using such a device for fixing a hose segment of the hose line, and a device (22) for monitoring the delivery and/or removal of a liquid, which has a device of this kind for fixing a hose segment of the hose line. The fixing of a hose segment is based on the use of the combination of a guide piece (28, 30) and of a securing piece (29, 31). With the guide piece (28, 30), the intersecting portions (27A, 27B) of the hose segment forming an eye (34) are fixed in such a way that the eye forms a loop (27) that closes together under a tensile load. With the securing piece (29, 31), that portion of the hose segment forming the eye, lying between the intersecting portions, is fixed such that, when the loop is closed, that portion of the hose segment forming the eye, lying between the intersecting portions, does not slip through the guide piece (28, 30). In an alternative embodiment, the intersecting portions of the hose segment are fixed, to form a loop (27), only by a guide piece (28) designed as a ring-shaped body. |
