摘要

The endpiece (1) has two pipes (2, 3) communicating with respective pairs of cannulas (21, 22, 31, 32) introduced in each nostril of a patient. The pipes are supplied with oxygen and nitrogen, respectively. The pipes (2, 3) comprise inclined walls (54, 55) connected to partitions (51, 52) of the pipes. The walls (54, 55) serve as bases for respective pipes (3, 2), where each wall forms an angle, between 30 and 60 degrees, with an axis of the pipes. The partitions are extended until ends of the cannulas.
