The embodiment of the invention provides a face mask gasket assembly, a manufacturing method of the face mask gasket assembly, and a breathing machine face mask, wherein the face mask gasket assembly is arranged on a face mask main framework, and comprises a gasket outer layer, a gasket filler and a hard gasket liner, wherein the gasket outer layer is made of textile materials; the gasket outer layer comprises a contact part matched with the face contour of a patient and a connecting part connected with the face mask main framework; a closed cavity structure is formed between the contact part and the connecting part; the gasket filler is filled inside the cavity structure, and is made of soft elastic materials, so that the face mask gasket assembly is pasted to the face of the patient; the hard gasket liner is positioned inside the cavity structure and is made of hard materials, so that the face mask gasket assembly is formed. The embodiment of the invention has the advantages that the processing cost of the face mask gasket assembly can be greatly reduced; the contact comfort between the gasket outer layer made of textile materials and the face is higher; the ventilation property is better.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a mask cushion assembly and a manufacturing method thereof, and a ventilator mask. Background technique [0002] CPAP (Continuous Positive Airway Pressure) ventilator mask is a product that needs to be worn by patients for a long time, and its wearing comfort has a great influence on the overall performance of the product. In practical applications, when the ventilator is working normally, it will output positive pressure airflow, which is transmitted to the patient's nose or mouth through the ventilator mask. Therefore, only the mask liner of the ventilator mask is in good contact with the patient's face. To ensure that there is no air leakage at the position where the face fits. [0003] At present, in order to achieve the comfort and tightness of the face fitting position, the mask liner is mostly made of silicone material. For example, an existing mask liner can spe...
