1. A nasal oxygen cannula that controls the supply of medical oxygen, wherein said cannula is characterized by comprising:
a. a plastic tube with two openings (1a) directed to the user's nostrils and two openings (1b) that connect to hoses (4) coupled to an oxygen source,
b. a mechanical system (2) arranged between the two openings (1a) directed to the nostrils (1a), where said system (2) consists of a sliding folded gate (2b) joined to a retractable element (2c) installed on a base (2d) connected with displacement directing elements (2e) arranged in the direction of the two openings (1b) that connect to the hoses (4),
c. an outer covering (2a) that covers the mechanical system (2) and is fixed to the plastic tube (1a), and
d. an electronic sensing system (3) arranged on the base (2d) comprising sensors (3a) that detect the deployment of the gate (2b) and send an electronic signal through transmission cables (3b), arranged in the back region of the cannula, to a data collection system.
