Abstract: The present invention is directed to a base member for a portable intravenous stand. The base member includes a plurality of segments configured to facilitate the close nesting or alignment of multiple portable intravenous stands; and thus reducing the amount of space required for storing the portable intravenous stands when not in use.

Abstract: A respiratory gas monitor testing system having a respiratory gas monitor coupled to a system for detecting a leak, wherein the system for detecting a leak has a flowmeter in fluid communication with both an inlet and an outlet of the respiratory gas monitor, with the exhaust of the flowmeter venting to atmosphere; a restriction valve, a sample pressure sensor, a flowmeter valve configured to allow the flowmeter to either measure sample flow rate or leak rate, a flow-smoothing buffer configured to improve flow measurement accuracy, and a system for simulating human breath; wherein the system for simulating human breath at elevated airway pressure has an air source, a calibration gas source, a breath simulation valve, a calibration gas valve, a sample pressure sensor, an air reservoir, a pressurized bottle with a pressure regulator and an orifice, and an air pump.

Abstract: A gas delivery apparatus for supplying an oxygen/air mix to a patient is discussed. Besides the conventional ability to adjust oxygen/air ratio independently via changes in the primary and/or secondary oxygen flow tube's flow rate adjustments, a flow meter is provided in the primary oxygen flow tube to give an accurate reading of the total flow of the oxygen/air mix exiting the venturi chamber of the apparatus.
