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. |
