Abstract
(EN)
Provided are a breathing support device humidifier temperature control method and breathing support device. The method comprises: introducing a pressure measurement apparatus to measure the amount of water in a water compartment, then obtaining the gas flow rate by means of a lookup table, further obtaining a required target temperature by means of looking up in the table, and the gas flow rate at the target temperature and the relationship between temperature and the amount of water in the water compartment. Thus at the same temperature, the temperature and humidification energy of the output gas under different gas flow rates are basically the same. The breathing support device comprises a humidifier and a humidifier controller; the humidifier controller is used for controlling the humidification amount and temperature generation of the humidifier; the humidifier comprises a water compartment; the water compartment is equipped with a heating apparatus and a pressure measurement apparatus; a heating panel is equipped with a temperature measurement apparatus; the target temperature can still be accurately controlled without external temperature and flow measurement modules.

L'invention concerne un procédé de régulation de température d'humidificateur de dispositif d'assistance respiratoire et un dispositif d'assistance respiratoire. Le procédé comprend : l'introduction d'un appareil de mesure de pression pour mesurer la quantité d'eau dans un compartiment d'eau, puis l'obtention du débit gazeux au moyen d'une table de consultation, l'obtention en outre d'une température cible requise au moyen de la consultation dans la table et du débit gazeux à la température cible et de la relation entre la température et la quantité d'eau dans le compartiment d'eau. Ainsi à la même température, la température et l'énergie d'humidification du gaz de sortie dans différents débits gazeux sont essentiellement les mêmes. Le dispositif d'assistance respiratoire comprend un humidificateur et un dispositif de régulation d'humidificateur; le dispositif de régulation d'humidificateur est utilisé pour réguler la génération de quantité d'humidification et de température de l'humidificateur; l'humidificateur comprend un compartiment à eau; le compartiment d'eau est équipé d'un appareil de chauffage et d'un appareil de mesure de pression; un panneau chauffant est équipé d'un appareil de mesure de température; la température cible peut encore être régulée avec précision sans modules de mesure de température et d'écoulement externes.
