Abstract
A tube clamp closes a flexible tube by applying a pinching force to walls of the flexible tube. The clamp includes a housing connected to a circular flange, the circular flange including a tubular wall surrounding a central bore and including at least one slot in the tubular wall sized to accept the flexible tube. A pinching element is positioned inside the central bore and is rotatable about a central axis of the circular flange. The pinching element includes a pinching projection that has a cross-sectional shape bound by a partial circle, and the partial circle has a radius substantially same as an inner radius of the tubular wall.
