| 摘要 |
The invention relates to a device for separating gas and liquid streams, especially in tracheal catheters of patients, comprising a housing having channels for the delivery and removal of sputum. The aim of the invention is to ensure unrestricted delivery and removal of respiratory air and reliable removal of sputum. To this end, the invention provides for the arrangement of an at least spherical segment-shaped closed housing (1) comprising tubular channels (4, 5) which are located a distance apart in the area of the end surface (2) of the housing (1), each leading to a connection to the tracheal catheter and guiding through respiratory air; and a tubular channel (6) for removing sputum to the exterior, the inner front end of this channel being sealed and a suction tube (7) consisting of highly flexible or resilient elastic material lying adjacent to the inside of the channel. Said suction tube can be bent or turned autonomously by the force of gravity, extends crosswise to the sputum channel (6) and from a distance can reach approximately as far as the inner wall of the housing (1) with its free end.
