    Abstract: A safety system is provided for a membrane-type blood oxygenator to prevent the possibility of gas embolism through the membranous barrier which separates the blood and the oxygen. The safety system includes a blood reservoir positioned at a higher horizontal level than the blood inlet of the oxygenator, so that a gravity head is maintained. In addition, a manometer is provided which has a fluid level to permit venting of the oxygen if the oxygen pressure exceeds a predetermined gas pressure, which gas pressure is lower than the minimum pressure of the blood in the oxygenator.

    Abstract: An apparatus for deriving an oxygen association rate curve for a blood sample wherein the sample is introduced into a transparentwalled cell and is deoxygenated by contact with a deoxygenated fluorocarbon material. The cell is located in the optical path of two time-shared respective monochromatic beams, one having a wavelength at which there is substantially no change in absorbance as between oxygenated and deoxygenated blood and the other having a wavelength at which there is a relatively large change in absorbance as between oxygenated and deoxygenated blood. The difference in absorbance through the cell of the two wavelengths is measured and recorded while oxygenated fluorocarbon titrant material is pumped through the cell, the cell having a restricted flow passage for the titrant material which acts to separate the blood therefrom and retain it in the cell while the titration is taking place. The sample may be either injected directly into the cell or be exposed to the interior of the cell through gas-permeable capillary tubes extending into the cell in gas-transfer relationship with the interior of the cell, the tubes being transparent and being located in the optical path of the time-shared beams.

    Abstract: A bubble-type blood oxygenator which comprises a flexible envelope having a blood flow passage with a blood oxygenating portion and a blood defoaming portion. A stiff backing carries the oxygenator in flat, stretched-out configuration with the result that the flow passage, when filled with blood and oxygen, exhibits reduced outward distension and sagging.

    Abstract: Oxygen to be administered to a patient is humidified by passing the oxygen through a standard water-containing intravenous solution bottle. A coupling assembly having an inlet tube and an outlet tube is inserted into the two openings defined by the stopper of the intravenous solution bottle, and is coupled to an oxygen supply. The connector assembly is capable of supporting the bottle, and carries a humidified oxygen outlet to which a nasal cannula is coupled.
