In order to improve a pump hose that is suitable for a peristaltic pump and by means of which transitions within the hose are avoided and which furthermore is operationally reliable, there is suggested a pump hose having a tubular center part (11) to which are arranged at both sides thereof connecting parts (12, 14) for connecting the pump hose (10) to other elements and having flange parts (17, 18) arranged at both sides for insertion into a cartridge part of the peristaltic pump. The tubular center part (11), the connecting parts (12, 14) arranged at both sides thereof and the flange parts (17, 18) arranged at both sides thereof are integrally produced from silicone. The connecting parts (12, 14) each have a head-like shaped sealing surface (16). The sealing surface (16) is surrounded by a substantially circular sealing bulge (20) that protrudes longitudinally beyond the sealing surface (16). The flange parts (17, 18) comprise means for inserting the pump hose (10) in a non-gas-tight manner, preferably also in a non-fluid-tight manner, into the peristaltic pump segment. |

1. A pump hose, particularly a silicone pump hose, for a peristaltic pump, for insertion into a peristaltic pump segment, comprising
a tubular center part, connecting parts arranged at both sides thereof, for connecting the pump hose to other elements, flange parts arranged at both sides thereof, particularly for insertion into a cartridge part of the peristaltic pump,characterized in that
the tubular center part, the connecting parts arranged at both sides thereof and the flange parts arranged at both sides thereof are integrally produced from silicone, preferably from platinum-linked silicone, the connecting parts each have a head-like shaped sealing surface, wherein the sealing surface is surrounded by a substantially circular sealing bulge that protrudes longitudinally beyond the sealing surface, and wherein the flange parts comprise means for inserting the pump hose in a non-gas-tight manner, preferably also in a non-fluid-tight manner, into the peristaltic pump segment, and the said means comprise nubs that are formed towards the tubular center part. |
