ABSTRACT:
Double-lumen tube adaptors for use with either single or dual anesthesia or ventillating machines enable the various features thereof to be utilized without airway disconnection or clamping, interruption of ventilation or the use of unreliable mechanical elements. The adaptor having a single machine-side entry port comprises a support frame and a pair of linear axially-extending cylindrical tubes in substantially parallel disposition extending rotatably through the frame, each of the tubes defining externally of the frame at one end a patient-side exit port adapted for communication with a patient via one lumen of a double-lumen tube and at the other end an entry port with a removable cap. Each of the tubes further defines within the frame interior intermediate the entry and exit ports an aperture extending appreciably in a direction transverse to the tube axes. A machine-side common entry port extends partially through the frame and is adapted for communication at a first or external end with an anesthesia or ventillating machine and adjacent a second or internal end with both of the tubes adjacent the tube apertures, the degree of communication between the common entry port second end and each of the tube apertures being a function of the rotational disposition of the respective tube.
