Abstract

Un réservoir d'humidification, comprenant un corps principal de réservoir d'humidification (1), et un conduit d'entrée d'air (2) et une sortie d'air (3) qui sont disposés sur le corps principal de réservoir d'humidification (1). Le conduit d'entrée d'air comprend une extrémité d'entrée d'air (21) et une extrémité de sortie d'air (22), la partie inférieure de l'extrémité d'entrée d'air (21) du conduit d'entrée d'air (2) est supérieure à la partie inférieure de l'extrémité de sortie d'air (22) dans la direction horizontale, et la longueur du conduit d'entrée d'air (2) est supérieure ou égale à la moitié de la longueur du corps principal de réservoir d'humidification (1) dans la direction du conduit d'entrée d'air (2) ou la longueur du conduit d'entrée d'air (2) est supérieure à la longueur la plus courte à partir de la sortie d'air (3) à la paroi où le conduit d'entrée d'air (2) est situé, de telle sorte qu'un liquide dans le réservoir d'humidification qui est évaporé et condensé en eau dans le conduit d'entrée d'air (2) retourne dans le réservoir d'humidification au moyen de l'inclinaison du conduit d'entrée d'air (2). Lorsque le réservoir d'humidification s'incline, le liquide n'entre pas dans le conduit d'entrée d'air (2); lorsque le réservoir d'humidification est retourné, la longueur à partir de la sortie d'air (3) à la paroi où le conduit d'entrée d'air (2) est situé est supérieure à la longueur du conduit d'entrée d'air (2), et lorsque le réservoir d'humidification est tourné selon un certain angle, l'eau s'écoule d'abord à travers la sortie d'air (3), mais ne pénètre pas dans le conduit d'entrée d'air (2), ce qui assure également que le liquide ne s'écoule pas dans un ordinateur principal d'un dispositif de thérapie respiratoire, ce qui permet d'obtenir un effet anti-débordement de 360°. L'utilisation d'une chambre traversante peut réduire considérablement l'impédance d'écoulement d'air et augmenter l'efficacité de sortie d'écoulement d'air.
