Abstract: A catheter clamp having a rounded open proximal side, a mirroring distal end, a planar bottom surface, and a top surface is provided. The top surface extends from the proximal side toward the distal end, the proximal side of the catheter clamp being formed such that the top surface can be moved in a vertically swinging position. The distal end of the clamp includes a locking lip that extends from the upper inside surface of the distal end. The top surface has a clamping surface which extends in a perpendicular direction from the top surface. The top surface is engaged beneath the locking lip such that the clamping surface clamps an inserted catheter tube, thereby stopping the flow of liquids through the catheter clamp. The top surface can be easily disengaged to release liquids through the catheter tube.
