Abstract
Abstract A device for aiding aspiration of meconium-stained fluids from infants at birth is disclosed. The device includes a unique endotracheal tube having a guide wire imbedded in its walls, a collection chamber in communication with said endotracheal tube, and a second tube having a bacterial/viral filter and a mouthpiece associated therewith which is used to evacuate the collection chamber and draw fluids through the endotracheal tube.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
A meconium aspiration device comprised of: (a) an endotracheal tube having an elongated, flexible, plastic, generally annular wall surrounding a central lumen of a generally uniform diameter and extending the entire length thereof from a proximal end to a distal end through which meconium tainted fluid materials can be aspirated and a stiffening wire totally embedded in said wall without encroachment into the central lumen, said stiffening wire extending substantially the length of said tube from a location a predetermined distance distal of said proximal end to a location just short of said distal end; (b) a fluid collection chamber coupled to said endotracheal tube; (c) disconnectable adapter means interposed between said endotracheal tube and said collection chamber for allowing rapid exchange of a vacuum source used during aspiration with a source of breathable gas for allowing ventilation through said endotracheal tube; and (d) an evacuation tube also coupled in fluid communication with said collection chamber and having a bacterial/viral filter disposed within said evacuation tube.
Claim 2
Dependent Claim
166 words
A meconium aspiration device comprised of: (a) an endotracheal tube having an elongated, flexible, plastic, generally annular wall surrounding a central lumen of a generally uniform diameter and extending the entire length thereof from a proximal end to a distal end through which meconium tainted fluid materials can be aspirated and a stiffening wire totally embedded in said wall without encroachment into the central lumen, said stiffening wire extending substantially the length of said tube from a location a predetermined distance distal of said proximal end to a location just short of said distal end; (b) a fluid collection chamber coupled to said endotracheal tube; (c) disconnectable adapter means interposed between said endotracheal tube and said collection chamber for allowing rapid exchange of a vacuum source used during aspiration with a source of breathable gas for allowing ventilation through said endotracheal tube; and (d) an evacuation tube also coupled in fluid communication with said collection chamber and having a bacterial/viral filter disposed within said evacuation tube.
Claim 3
Dependent Claim
26 words
The device as in claim 1 and further including a mouthpiece member associated with one end of said evacuation tube through which air can be drawn.
Claim 4
Dependent Claim
26 words
The device as in claim 1 wherein said endotracheal tube includes an opening of a predetermined size passing through said wall near the distal end thereof.
Claim 5
Dependent Claim
21 words
The device as in claim 3 wherein the wall of said endotracheal tube is formed with a blunt, beveled distal tip.
