Clover's Portable Regulating Ether Inhaler - without case
Date of manufacture:
This example of Clover's Portable Regulating Ether Inhaler is without a case. It includes only an angle connector for a reservour bag. The black antistatic neoprene bag is a recent addition. A malleable, close fitting face mask would have been applied to the male taper and the original mask would have had a slot in its connector to accommodate the pointer of the vaporiser so that the pointer was always facing the patient's forehead. Adjustment of the delivered ether concentration was achieved by rotating the whole vaporiser around the axis of the mask mount. See also 20110072.
