Roller pincher for setting the regulation cross-section of a flexible tubing
First Claim
1. A roller pincher for setting a regulation cross-section of a flexible tubing which is connectable to a medical fluid container, the roller pincher comprising:
- an elongate pinch housing being U-shaped in cross-section with two sidewalls and with a web wall connecting said side walls;
a pinch roller which acts on the flexible tubing positioned in said housing, said pinch roller being arranged longitudinally displaceable in said sidewalls, said pinch roller having an annular notch on one circumferential corner region for forming the regulation cross-section of the flexible tubing in cooperation with said pinch housing, wherein said pinch housing in a transition region from said web wall to one of said sidewalls which is distant to said annular notch of the pinch roller, said transition region comprises an inner elongate side guide surface for the flexible tubing held between the web wall and the pinch roller, said side guide surface projecting into said pinch housing and running inclined to a longitudinal middle plane of said housing.

Abstract
An elongate pinch housing is provided which is U-shaped in cross-section with two sidewalls and with a web wall connecting these. A pinch roller is longitudinally displaceable in these sidewalls with an annular notch at its one circumferential corner region for forming the regulation cross-section of the flexible tubing. The pinch housing in its transition region from the web wall to that sidewall which is distant from the annular notch of the pinch roller is provided with an inner, elongate side guide surface for the flexible tubing. The side guide surface projects into the pinch housing and runs inclined to its longitudinal middle plane so that the flexible tubing inserted in the pinch housing is subjected to a transverse movement.

15. A roller pincher arrangement for a flexible tube, the arrangement comprising:
-
a pinch roller having a circumferential corner region defining an annular notch;
an elongate pinch housing having a U-shaped cross-section with first and second sidewalls and with a base wall connecting said side walls, said pinch roller being arranged in said pinch housing with said annular notch being arranged adjacent said first sidewall and forming a regulation cross-section of the flexible tube in cooperation with said pinch housing, said pinch housing having a transition region from said base wall to said second sidewall, said transition region including an inner elongate side guide surface for the flexible tube held between said base wall and said pinch roller, said side guide surface projecting into said pinch housing and running inclined to a longitudinal middle plane of said housing.
