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 noise reduction structure for a ventilator pipeline, which belongs to the field of medical equipment. Background technique [0002] Ventilators are now often used in home rehab, amid growing awareness of the various ailments that can result from poor breathing, such as snoring. However, because ventilators use fans to produce compressed air to supply patients with breathing, during the process of producing compressed air, the high-speed operation of the turbo blower will produce unpleasant vibration noise and aerodynamic noise, which will seriously affect the patient. sleep quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe, reliable and low-noise ventilator pipeline noise reduction structure. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A ventilato...
