Device for connection to a respiratory gas line
First Claim
1. A device for connection to a respiratory gas line comprising:
- a terminal board having a first engagement surface thereon and a respiratory gas line defined therein with a first pair of connecting lines extending from the respiratory gas line to the first engagement surface and a recess opening;
an equipment unit connectable to the respiratory gas line for receiving gas therefrom, treating the gas received and returning treated gas to the respiratory gas line, said unit having an adapter with a second engagement surface and a second pair of connecting lines extending to the second engagement surface for receiving and returning gas to and from said unit;
alignment means on said adapter and terminal board for aligning said first pair of connecting lines with said second pair of connecting lines when said first engagement surface is engaged with said second engagement surface;
a valve element movable in said terminal board from an "on" position for establishing flow in said first pair of connecting lines between said respirator gas line and said first engagement surface, and to an "off" position for establishing communication between said first pair of connecting lines and blocking communication of said first pair of connecting lines to said first engagement surface; and
a control lever movably mounted in said adapter extendible through said recess opening into engagement with said valve element when said first and second engagement surfaces are engaged with each other to move said valve element.

Abstract
A device for connection to a respiratory gas line, particularly a narcosis apparatus, comprising, a terminal board having a first engagement surface thereon and a respiratory gas line defined therein with a first pair of connecting lines extending from the respiratory gas line to the engagement surface. An equipment unit for example, an evaporator or flowmeter is provided for connection to the respiratory gas line and has an adapter with a second engagement surface and a second pair of connecting lines extending to the second engagement surface. Structure is provided to align the first and second pairs of connecting lines to each other when the first and second engagement surfaces are engaged with each other to establish communication between the respiratory gas line and the second pair of connecting lines. A valve is also provided either in the first pair of connecting lines or in the second pair of connecting lines. The valve in the first pair of connecting lines takes the form of a bypass line bypassing the first pair of connecting lines.
