A duct opening close to the patient's respiratory passages provides a supply of additional oxygen from a source.

The device comprises a heat sensor element exposed to the temperature changes between the air inhaled and the air exhaled which cause corresponding voltage changes across its terminals; a coupler supplying signals which are a function of these voltage changes; an electromagnetic valve in the duct and controlled by a control element during the patient's various stages of respiration.

The invention is applicable more particularly to oxygen therapy devices worn on the person e.g. in the fashion of spectacles.
