Embodiment Construction

[0015] In a preferred embodiment, the stabilizing wire is applied to the outside of the membrane tube.

[0016] In another preferred embodiment, the stabilizing wire is applied to the inside of the membrane tube.

[0017] In yet another preferred embodiment, the stabilizing wire is loosely inserted into the membrane tube.

[0018] The membrane tube generally has a cross-sectional circumference (inner side) of 6 mm to 200 mm, preferably 9 mm to 100 mm, particularly preferably 12 mm to 80 mm, in particular 10 mm to 20 mm.

[0019] The film tubing preferably has the property that the inside does not exhibit stickiness at typical medical institution heat treatment temperatures, especially at the sterilization temperature of 121°C.

[0020] Therefore, the inner surface of the membrane tube is generally preferably roughened. The structure can be formed eg by embossing, and the roughening preferably takes place in extrusion by choosing a suitable die shape.

[0021] This roughness...

Abstract

A film tube containing a stabilization filament has a low tendency to kinking and is suitable in particular for use in the medical sector in medical devices.

Description

technical field [0001] The invention relates to a membrane tube, a manufacturing method of the membrane tube and its application in the field of medical technology. Background technique [0002] A problem that frequently arises in the field of medical technology is the transfer of liquids, preferably sterile, from one container to another or into the human body, for example in the case of infusions. [0003] Currently, in medical institutions, fluids are mainly delivered through specially made tubes. Such tubes are expensive to manufacture, all the more so given the tense financial environment for health systems around the world. In addition, the tubes are often prone to kinks, resulting in blockage of the tubes. [0004] Therefore, in medical institutions, there is a need for a device for delivering liquids that overcomes the disadvantages of known systems, in particular that can be produced at low cost and that is less prone to kinks. [0005] So-called membrane tubes a...
