摘要：【中文】本发明涉及通气治疗设备领域，公开了一种用于通气治疗设备的减噪结构以及通气治疗设备。所述减噪结构(70)包括第一微孔板(71)和第一背板(72)，所述第一微孔板(71)与所述第一背板(72)相互间隔地叠置以在两者之间形成第一腔室(73)，所述第一微孔板(71)的背离所述第一背板(72)的板面用于限定所述通气治疗设备的气道(74)，以使所述气道(74)内的气体沿所述第一微孔板(71)的所述板面流动。本发明的减噪结构减噪频带宽，能够有效降低气道中的气动噪声，提高患者使用通气治疗设备的满意度。另外，所述减噪结构还具有加工、设计简单，成本低，应用环境广泛的优点。 【EN】The invention relates to the field of ventilation treatment equipment, and discloses a noise reduction structure for ventilation treatment equipment and the ventilation treatment equipment. The noise reduction structure (70) comprises a first microporous plate (71) and a first back plate (72), the first microporous plate (71) and the first back plate (72) are stacked at a distance from each other to form a first chamber (73) therebetween, and the plate surface of the first microporous plate (71) facing away from the first back plate (72) is used for defining an air channel (74) of the ventilation therapy device, so that the gas in the air channel (74) flows along the plate surface of the first microporous plate (71). The noise reduction structure has wide noise reduction frequency band, can effectively reduce the pneumatic noise in the air passage, and improves the satisfaction degree of patients using the ventilation treatment equipment. In addition, the noise reduction structure also has the advantages of simple processing and design, low cost and wide application environment.
