A charge pump generates a first sub up current and a second sub up current that vary complementarily with a change in a voltage at an output terminal. The data processing device includes an attempting unit, a confirming unit, a notifying unit, a first setting unit, and a second setting unit. Each of the first and second electrodes comprises a contact aperture spaced from the center axis, and a contact element positioned within each of the contact apertures. The modification removes a pattern of tubing opposite the suction tube to form integral clips that retain the tube sump upon an existing endotracheal tube.
