Adaptor for use with a double lumen endobronchial tube

摘要

An adaptor (10) is disclosed for directing breathing gas from a source of such gases to the lumen of a double lumen endotracheal tube. The adaptator has three operative conditions. In one of these conditions, breathing gases flow to both tubes via a fitting (16) and one of a pair of fittings (22). In a second condition breathing gases flow to one lung via one of the fittings (22) and the other lung is connected to a deflation port (66) of the adaptor so that it can be collapsed. In a third condition breathing gases flow through the other fitting (22) and hence to the other lung, and the one lung is deflated through another deflation port. Markings (20, 26, 28) are provided on the external surface of the adaptor to enable the user to determine which of the three conditions it is in.
