Abstract
To provide a simple embodiment of a rotor (2) for a fluid pump which is nevertheless very flexible in handling and compressible, in accordance with the invention a conveying blade is provided having at least two struts (12, 13, 14) and a membrane spanned between them in the expanded state, wherein the struts each have at least one joint, in particular more than one joint, which enables an angling in a first direction in a first movement plane and bounds an overelongation beyond an elongation angle of in particular 180° in the opposite second direction. In particular when a plurality of joints (15, 16, 17) are provided at the struts, they, and with them the conveying blades, are particularly flexible for simple compressibility.
Claims2
A conveying blade for a radially compressible and expandable rotor (2) of a fluid pump having at least two struts (12, 12′, 12″, 12′″, 13, 13′, 131′, 13″, 14, 14-, 14″, 1′⋅′, 18, 19, 41, 42, 27, 27′, 27″, 28, 28′, 28*′) and a membrane held thereby in the expanded state, wherein the struts each have at least one joint, in particular more than one joint (15, 15′, 16, 16′, 17, 17*, 15′″, 16′″, 17»″, 21, 21′, 22, 22′, 23), which enables a further going angling in a first direction in a first movement plane than in the opposite second direction within the first movement plane and in the second direction bounds an overelongation of the strut beyond an elongation angle, which preferably amounts from 160° to 200° most preferably from 175° to 185°, characterized in that at least one joint is spaced apart from a hub of the rotor;
- and in that a first section (42) of the strut is pivotably journalled at a second section (41) of the strut.
