Abstract
A heatable hose (1), in particular a respiration hose, having a flexible hose wall (4), shall guarantee through its design that a contact of the electric conductors or heating wires (14, 16) accommodated in the hose (1) and, thus, a short circuit, is excluded. For this purpose, the hose (1) is equipped with a plurality of reinforcing ribs (8, 12, 20, 22), each of which winds around the hose wall (4) in the manner of a helical line and which form together a multiple-threaded helical line, at least two reinforcing ribs (8, 12) being provided, each of which encloses a heating wire (14, 16) designed for heating the hose. Each heating wire (14, 16) is preferably a single-conductor wire.
Claims19
A heatable hose (1) comprising:
- a flexible hose wall (4);
- a plurality of reinforcing ribs (8, 12, 20, 22), each of which winds around the hose wall (4) in the manner of a helical line and which form together a multiple-threaded helical line, at least two reinforcing ribs (8, 12) being provided, each of which encloses a heating wire (14, 16) designed for heating the hose (1);
- wherein the reinforcing ribs (8, 12, 20, 22) have different cross-sectional shapes and/or cross-sectional dimensions;
- and
- wherein exactly one reinforcing rib (8, 12, 20, 22) protrudes over the other reinforcing ribs (8, 12, 20, 22) in a direction normal to the hose axis.
A heatable hose comprising a hose wall that is flexible, and at least two reinforcing ribs each winding in a helical line around the hose wall that together form a multiple threaded helical line, with at least one of the ribs enclosing a heating wire for heating the hose, with at least two of the ribs having different cross-sectional shapes and/or dimensions, and with exactly one of the ribs protruding over the other ribs in a direction normal to the hose axis.
