Abstract
Improvements in oscillating circuit anesthesia devices, consisting essentially of the fact that the communication between the mask and the gas regeneration chamber is established by means of a double tube, at both ends of which there are two valve chambers, both having ducts that constitute the double tube, one at its end corresponding to its coupling with the mask, and the other at the opposite, of synchronous valves operated by the air flow, which establish a circuit in a single direction.
