ABSTRACT:
A clamp for controlling the flow through a hose or flexible tubing such as is used in intravenous systems comprises a pair of parallel leg members joined by a curved end portion, each leg containing elements capable of clamping down on the tubing when the clamp is brought into closed position. The clamp contains a catch arm which sits on a flexible arm member at the free end portion of the clamp, and retains the upper leg member when the clamp is closed. Optionally, this catch arm can be multi-tiered, allowing the clamp to be closed at a variety of positions, each restricting a different amount of flow. When clamped, the clamping elements from each leg are alongside each other, crimping the tubing at two slightly separated points, and maximizing the clamping effect on the tubing. There are openings through the curved end portion and through the flexible arm member to receive the tube, and to retain it in position to maximize the effect of the clamp.
