US 5,427,145 A · Connector with integral valve

Abstract

A connector is provided for mounting on an anesthetic vaporizer to connect the inlet of the vaporizer with a discharge port of a container of liquid anesthetic. The connector includes a first coupling attachable to the vaporizer and defining a first passage communicating at one end with the vaporizer inlet. A second coupling is attachable to the container and defines a second passage communicating at one end with the container discharge port. A third passage defined by one of the couplings and communicates with one of the first and second passages. A combination valve and mounting structure is cooperatively defined by the couplings to accommodate pivoting of the second coupling to a closed position occluding the first and second passages, to a raised fill position establishing communication between the first and second passages, and to a lowered drain position in which the first and second passages communicate through the third passage.

A connector suitable for mounting on an anesthetic vaporizer for connecting the vaporizer with a discharge port of a container of liquid anesthetic, said connector comprising:

a first coupling attachable to said vaporizer at one end and carrying a cylindrical portion at an opposite end, and defining a first through passage communicating at said one end with said vaporizer;
a second coupling attachable to said container at one end and carrying an annular wall at an opposite end, and defining a second through passage communicating at said one end with said container discharge port;
a third passage defined by the cylindrical portion of said first coupling and permanently communicating with said first passage;
and
said cylindrical portion of said first coupling cooperatively received in said annular wall of said second coupling to accommodate pivoting of said second coupling to a closed position occluding said first and second passages, to a raised fill position establishing communication between said first and second passages, and to a lowered drain position in which said first and second passages communicate through said third passage.

A connector suitable for mounting on an anesthetic vaporizer for connecting the vaporizer with a container of liquid anesthetic, said connector comprising:

a first coupling attachable to said vaporizer and including a first leg having a distal end for insertion into said vaporizer and having a generally cylindrical portion at a proximal end of said first leg, said first leg distal end defining a discharge port and said cylindrical portion defining an inlet port, a drain port, and a third passage diverging from said first passage to said drain port;
a second coupling attachable to said container and including a second leg having a proximal end for attaching to said container and having a generally annular wall at a distal end for rotatably receiving said first coupling cylindrical portion, said second leg proximal end defining an influent port and said annular wall defining an outlet port;
said influent port and said outlet port connected via a second passage;
and
said cylindrical portion of said first coupling being received in said annular wall of said second coupling accommodating pivoting of said second coupling relative to said first coupling among
(1) a fill position in which said first and second passages are in communication through said first coupling inlet port and second coupling outlet port,
(2) a drain position in which said third passage communicates between said first and second passages, and
(3) a closed position occluding flow between said first and second passages.
