ABSTRACT:
A safety slide clamp to prevent free flow when tubing is disconnected from an I.V. administration device comprises a blade formed with a tear-drop shaped aperture through which the tubing is positioned. The aperture includes an enlarged portion and a narrow portion which is tapered to form a slot that is engageable with the tubing to prevent flow therethrough. A base formed with a well is attached to the pump and is adapted to slidably receive the blade of the slide clamp. Retaining means formed on the base are spaced to support the blade and retain the tubing in a recess between the fingers and the base. Placement of the tubing into the recess and subsequent insertion of the blade into the well permits operational fluid flow through the tube. Subsequent retraction of the blade urges the tubing into the slot to prevent free flow from the tube upon its removal from the device.
