The present invention provides improvements in the feedback and control systems employed in the field of ventilation therapy. In particular, a system for delivering a supply of gases to a patient is described which incorporates a detachable cartridge or open tubular section (22) used to house a mechanism (11) which senses the humidity, temperature, flow and other attributes of the flowing gas. Information obtained from the sensor may be used to provide feedback to a controller (9) which controls the humidification mechanism in order to provide optimally humidified gases to a patient (1). It will be appreciated that the feedback and control system as described in the preferred embodiment of the present invention can be used in respiratory care generally or with a ventilator.

L'invention porte sur des améliorations de la rétroaction et des systèmes de commande utilisés dans le domaine des traitement de ventilation. L'invention concerne en particulier un système permettant de fournir un apport de gaz à un patient, comprenant une cartouche amovible ou une section tubulaire (22) ouverte destinée à abriter un mécanisme (11) qui détecte l'humidité, la température, l'écoulement et d'autres attributs du gaz circulant. Les informations relevées par le capteur peuvent servir à fournir une rétroaction à une unité de commande qui commande le mécanisme d'humidification de manière à fournir des gaz humidifiés de manière optimale. Dans la forme de mise en oeuvre préférée, cette rétroaction et ces systèmes de commande peuvent être utilisés de manière générale pour les soins respiratoires ou conjointement à un ventilateur.
