Noise-reducing respiratory device

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 comprise 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 to enter 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 and be connectable to the casing;
• wherein the noise-reducing gas passage is configured to reduce noise by extending an airflow path of the breathable gas,
• wherein an interior space of the noise-reducing gas passage through which the breathable gas flows does not comprise foam,
• 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 the other side to connect to a breathing hose to provide the continuous breathable positive pressure gas to the patient's airway;
• and
• electronic components provided between the casing and the noise-reducing gas passage;
• wherein a ratio of an interior volume of the noise-reducing gas passage to a volume of the blower is between 3 and 18, and a ratio of an internal volume of the casing to the interior volume of the noise-reducing gas passage is between 1 and 5, and
• the noise-reducing respiratory device is configured to provide the breathable gas to the patient through the connected breathing hose during sleep treatment;
• and
• wherein the at least one air intake and the at least one air outlet of the casing are disposed on two wall surfaces of the casing.
