TUBE RETENTION DEVICE FOR A ROLLER PUMP HEAD

摘要

A tube retention device includes first and second wall surfaces having a first attachment point and a second attachment point, respectively. A first clamp component, having a first tube-engagement surface, is pivotably coupled to the first wall surface at the first attachment point, and configured to rotate about an axis at least approximately normal to the first wall surface. A second clamp component, having a second tube-engagement surface, is pivotably coupled to the second wall surface at the second attachment point, and configured to rotate about an axis at least approximately normal to the second wall surface. The clamp components may be configured to rotate, in opposite directions and in response to application of force by a tube piece upon the tube-engagement surfaces, from an open position to a closed position, where the tube piece is retained between the clamp components when the clamp components are in the closed position.
