The design and performance of an apparatus for producing accurately known trace concentrations of anaesthetic agents in air is described. The generator was constructed to facilitate the testing and calibration of equipment used in measuring the personal exposure of operating theatre staff to waste anaesthetic gases, and operates on the principle of the controlled injection of the pure anaesthetic agent into a diluting air stream. It is compact, simple to construct and easy to operate. Furthermore, it has a short stabilization time and can provide a wide range of predetermined concentrations with very good repeatability. It appears to be considerably more flexible than systems which have been described previously and should be of interest to groups involved in monitoring pollution in the operating theatre.
本文描述了一种用于在空气中产生精确已知痕量浓度麻醉剂的装置的设计与性能。该发生器的构造便于对测量手术室工作人员对废麻醉气体个人暴露的设备进行测试和校准，其工作原理是将纯麻醉剂控制注入稀释气流中。它结构紧凑、易于构建且操作简便。此外，它的稳定时间短，能提供范围广泛的预定浓度，且重复性非常好。它似乎比先前描述的系统灵活得多，应该会引起参与手术室污染监测的团体的兴趣。
