1. A noise-reducing respiratory device configured to provide continuous breathable positive pressure gas to a patient to treat respiratory system-related disorders, the noise-reducing respiratory device comprising:
a casing configured to include at least one air intake and at least one air outlet;
a blower having an inlet and an outlet, configured to continuously pressurize breathable gas entering an interior of the noise-reducing respiratory device to form the continuous breathable positive pressure gas;
a noise-reducing gas passage configured to accommodate the blower, the noise-reducing gas passage being sealably connectable to the casing through a sealing component;
wherein the noise-reducing gas passage is configured to reduce noise by extending an airflow path of the breathable gas,
wherein a shortest path for the continuous breathable positive pressure gas inside the casing from the at least one air intake to the at least one air outlet is at least 160 mm,
the at least one air intake is configured to receive the breathable gas into the noise-reducing gas passage to supply the blower with the breathable gas to generate the continuous breathable positive pressure gas, and
the at least one air outlet is configured on one side to communicate with the outlet of the blower, and configured on another side to connect to a breathing hose to provide the continuous breathable positive pressure gas to the patient's airway;
electronic components provided between the casing and the noise-reducing gas passage; and
a soundproofing material provided outside the noise-reducing gas passage between the noise-reducing gas passage and the casing,
wherein a ratio of an interior volume of the noise-reducing gas passage to a volume of the blower is between 3 to 18, and a ratio of an internal volume of the casing to the interior volume of the noise-reducing gas passage is between 1 to 5, and
the device is configured to provide the breathable gas to the patient through the connected breathing hose during sleep treatment.
