Abstract

The invention discloses a pipeline noise reduction structure for a breathing machine. The pipeline noise reduction structure for the breathing machine comprises a draught fan (1) and is characterized in that the draught fan (1) comprises a draught fan body (2) and a compressed air output port (3), the periphery of the draught fan body (2) is tightly wrapped by a breathable soft layer (4), a sealing cabin (5) is arranged outside the breathable soft layer (4), the upper portion and the lower portion of the sealing cabin (5) are respectively provided with an air ventilation chamber (6), a first air input port (9) is formed in the upper portion of the sealing cabin (5), a second air input port (10) is formed in the lower portion of the draught fan (1), and a through hole (11) used for penetrating through the compressed air output port (3) is formed in the periphery of the sealing cabin (5). The pipeline noise reduction structure for the breathing machine is reasonable in design, simple, low in cost, safe and reliable, noise of the breathing machine is effectively reduced, it is ensured that a patient can easily fall asleep, and the sleeping quality and the living quality of the patient are improved.

Description

Technical field [0001] The invention relates to a pipeline noise reduction structure of a ventilator, belonging to the field of medical equipment. Background technique [0002] At present, as people's awareness of poor breathing, such as snoring, can cause various diseases, ventilators are often used in family rehabilitation. However, since ventilators use fans to produce compressed air to supply patients with breathing, in the process of producing compressed air, the high-speed operation of turbofans will produce unpleasant vibration noise and aerodynamic noise, which will seriously affect patients Quality of sleep. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a safe, reliable, low-noise ventilator pipeline noise reduction structure. [0004] In order to solve the above technical problems, the technical solutions adopted by the present invention are: [0005] A duct noise reduction structure for a ventilator, including...
