Abstract:
Valve arrangement for control of a fluid through-flow between a first and a second fluid space comprising:a flexible tubing piece (2) of elastomer material, having deformed and undeformed states, said tubing piece having an outer wall side adapted to be in contact with the first fluid space (5', 14) and a lumen (6) adapted to be joined with the second fluid space (9,24),at least one through slot (11) in the wall of the flexible tubing piece (22) which is closed when the flexible tubing piece (2) is in the undeformed state due to inherent restoring force of the elastomer material and which can be opened by deformation of said flexible tubing piece (2), andan actuation part (10, 19) on said tubing piece (2) by which the tubing piece (2) can be deformed for control of fluid flow through said at least one slot (11),wherein the actuation part is formed as a tube piece (10) disposed in the lumen (6) of the flexible tubing piece (2) and ending in front of said at least one slot (11).
