Cranlea Douglas Bag Systems

The traditional way of measuring Oxygen Uptake has been to use Douglas Bags. However, difficulty in being able to mate the various components and avoiding leaks has always been a problem. For many years, Cranlea have been producing their own custom-built frames. Each frame is supplied with Hans Rudolph valves and stopcocks, widely regarded as the Gold Standard in respiratory accessories, giving you a high quality, leak free solution. Two Douglas Bag Packages are available:
