Abstract: A monitoring device which monitors the extent of infusion of intravenous solutions and provides an alarm signal when such infusion has progressed to a predetermined degree. The device comprises a cylindrical container to which is coupled, at its upper end, an attaching member for suspending the device from an intravenous solution supporting stand. Peripherally disposed about the cylindrical container are electrical sockets adapted such that each socket may accept an associated electrical plug. Extending through and below the lower end of the cylindrical container is a suspension member having a hook section for suspending an intravenous solution container. A helical spring is disposed within the cylindrical container, coaxially surrounding that portion of the suspension member which extends into the cylindrical container. The vertical position of the spring is defined by the lower internal end of the cylindrical container and by the upper extremity of the suspension member disposed within the container.
