Title
(EN) IMPROVED POWER MANAGEMENT IN RESPIRATORY TREATMENT APPARATUS
(FR) AMÉLIORATION DE LA GESTION DE LA PUISSANCE DANS UN APPAREIL DE TRAITEMENT RESPIRATOIRE
Abstract
(EN) A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator (104) over other accessories such as the heating elements (111, 135) of a humidifier (112) and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.
(FR) L’invention concerne un appareil de traitement respiratoire qui fournit un traitement respiratoire. L’appareil selon l’invention présente une gestion améliorée de la puissance, pour permettre une consommation de puissance plus efficace et un fonctionnement avec des unités d’alimentation électrique, telles qu’une batterie. Selon un mode de réalisation, la gestion de l’énergie accorde la priorité au générateur de débit (104) par rapport aux autres accessoires tels que les éléments chauffants (111, 135) d’un humidificateur (112) et/ou un tube de délivrance. Le générateur de débit peut commander le fonctionnement des éléments chauffants en fonction d’un cycle respiratoire détecté. Par exemple, la cadence de fonctionnement des éléments chauffants peut être imbriquée avec la partie d’une phase inspiratoire du cycle respiratoire pour permettre au générateur de débit de fonctionner pendant un fonctionnement en énergie de pointe sans consommation de courant ou avec une consommation de courant réduite de ces composants. Le fonctionnement de groupes distincts de composants du système (p. ex. différents éléments chauffants) peut également être imbriqué pour empêcher des fonctionnements en énergie de pointe simultanés.
