Title
(EN) HEATER PLATE ASSEMBLY IN HUMIDIFIER SYSTEMS FOR MEDICAL USE
(FR) ENSEMBLE PLAQUE CHAUFFANTE DANS DES SYSTÈMES D'HUMIDIFICATEUR À USAGE MÉDICAL
Abstract
(EN)
An improved system and method of determining a low water and/or water-out condition in a humidifier chamber of a respiratory or surgical humidifier system can use a specific frequency band to detect changes in a temperature of a heater plate. The temperature changes can correlate to the specific heat capacity value of the humidifier chamber. The low water and/or water-out detection process can be performed without having to determine the gases flow rate and/or can be run continuously. A heater plate assembly of the system can include a compliant insulation sheet to improve thermal coupling between the heating element and the top heating plate of the heater plate assembly, thereby improving the low water and/or water-out detection process.
(FR)
L'invention concerne un système et un procédé améliorés de détermination d'un état de niveau d'eau bas et/ou d'absence d'eau dans une chambre d'humidificateur d'un système d'humidificateur respiratoire ou chirurgical pouvant utiliser une bande de fréquences spécifique pour détecter des changements dans une température d'une plaque chauffante. Les changements de température peuvent être corrélés à la valeur de capacité thermique spécifique de la chambre d'humidificateur. Le procédé de détection de niveau d'eau bas et/ou d'absence d'eau peut être réalisé sans devoir déterminer le débit de gaz et/ou peut être exécuté en continu. Un ensemble plaque chauffante du système peut comprendre une feuille d'isolation souple pour améliorer l'accouplement thermique entre l'élément chauffant et la plaque chauffante supérieure de l'ensemble plaque chauffante, ce qui permet d'améliorer le procédé de niveau d'eau bas et/ou d'absence d'eau.
