Abstract
A noise-reducing respiratory device configured to improve or treat respiratory system-related disorders such as sleep apnea. The device includes a noise-reducing gas passage located inside a casing of the device, and is connected to the casing. The casing of the respiratory device also has at least one air intake and at least one air outlet. The air intake is configured to receive breathable gas into the chambers of the noise-reducing gas passage. The air outlet is configured on one side to communicate with an outlet of the blower, and on the other side, it connects to a breathing hose. Additionally, electronic components and a soundproofing material are provided between the noise-reducing gas passage and the casing of the device. Furthermore, there is no foam present where the internal gas flows through the respiratory device.
