The development of a new method for achieving respiratory isolation in hospitals, clinics, and residential facilities, in response to the increasing risk of transmission of tuberculosis and the limitations of the currently available isolation systems.
Ultraviolet (UV) light and ultra-low-penetration air filtration were combined with a ventilation unit and adapted for use in modular isolation rooms or for conversion of existing rooms.
The ventilation-filtration unit efficiently cleared bacterial aerosols and particles > 0.2 microns from the air, maintained required negative pressures and airflows, and provided directional airflow within rooms.
鉴于结核病传播风险增加以及现有隔离系统存在局限性，开发一种在医院、诊所和住宅设施中实现呼吸隔离的新方法。
将紫外线（UV）光和超低穿透性空气过滤与通风装置相结合，并适用于模块化隔离病房或现有病房的改造。
通风过滤装置有效地清除了空气中的细菌气溶胶和大于0.2微米的颗粒，维持了所需的负压和气流，并在病房内提供了定向气流。
