Abstract
A peristaltic pump composed of a tubular cylindrical housing closed at opposite ends, a flexible tube wound in single and complete helix circumferentially around the inner wall of said housing with its opposite end portions passing outwardly through two substantially coplanar and tangentially disposed ports in the housing, a rotatable assembly axially disposed within the housing and carrying at least one radially displaceable roller, linearly slidable setting bar means within said rotatable assembly operable to extend said roller into compressive contact with the helix of tubing, and power means for rotating said assembly to cause said roller to traverse said helix to force fluid content of said tubing along same.
