A double-action adaptor or connection plug (1) is provided for use in testing patient narcosis systems of the Bain type, for connecting a pressure measurement apparatus (18) to that location where the patient mask (11) normally is situated. The adaptor (1) has special dimensions adapted to provide seal by a pressure fit, and at the same time clearance in relation to the mouths of the narcosis hose (13, 14), depending on what sort of test is made. It is possible to test the inner hose (14) or the patient system separately, or the complete system, i.e. the outer hose (13) and tightening parts connected thereto. |
