摘要：A device for use in constructing a breathing circuit has at least a first tube and afilter; the filter has a proximal and a distal end; the first tube is attached to the filterdistal end. A second tube can be attached to the filter proximal end, wherein the secondtube can be detached from the filter for reuse in a breathing circuit formed with theforegoing components. The filter and the first tube may be disposed of after a singleuse. The first tube has a length sufficient to maintain the filter at a desired distance froma patient airway device when connected thereto. In a preferred embodiment, a fresh gasoutlet is provided at the distal end of the first tube resulting in minimal or substantiallyno mixing space in the circuit, while the disposable first tube and filter create less medicalwaste than that created by prior art circuits. Mixing space refers to space distal of thefresh gas outlet into the circuit where the fresh gases can mix with recirculated or othergases. In embodiments, the mixing space is less than 15 cm3 or less than about 5 cm3, andthe distal disposable filter and tube device is less than 50 cm in length.
