Description

Technical Field

[0001] This utility model relates to a mesh, and more particularly to a filter pressure ring mesh, belonging to the field of ventilator technology. Background Technology

[0002] The ventilator filter is a crucial component, performing two core functions: filtration and protection. The filter effectively removes fine particles such as dust, pollen, bacteria, and viruses from the air, ensuring clean and safe air inhaled by the patient. This helps reduce the risk of respiratory infections and improves treatment outcomes. Simultaneously, it protects the ventilator's internal components from impurities and damage, thus extending the ventilator's lifespan.

[0003] Existing ventilator filter designs typically consist of two parts: a compression plate and a filter element, bonded together with adhesive. This adhesive releases harmful substances during use, which can enter the patient's respiratory tract during ventilator operation, posing a potential threat to their health. Furthermore, adhesive bonding hinders the tension of the filter element. The filter element needs to maintain a certain tension to ensure its filtration efficiency and stability, but adhesive bonding makes it difficult to achieve ideal tension, leading to loosening or deformation of the filter element during use, thus affecting filtration efficiency and lifespan. Therefore, a filter compression ring mesh is proposed. Utility Model Content
