Abstract

Abstract An instrument for integrated monitoring of a patient''s physical condition includes a suction tube for insertion in his esophagus, the tube being provided with an inlet in one end for stomach fluids and an outlet in its opposite end for connection to a suction machine. A portion of the tube is encircled by an acoustic tube that is spaced from it, although the inner end of the acoustic tube is sealed to the suction tube in a location adjacent to, but spaced from, the inlet end of the suction tube. The outer end of the acoustic tube has an opening through which the suction tube emerges, and an outlet for connection to a sound-monitoring device. The inner end portion of the acoustic tube has lateral openings therein covered by diaphragm means. A plurality of spaced electrode bands encircle the acoustic tube adjacent the sleeve and are connected to wires extending outwardly along the acoustic tube and away from its outer end for connection to a heart-monitoring machine.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 204 words
A multipurpose esophageal instrument for integrated monitoring of a patient''s physical condition, comprising a suction tube for insertion in a patient''s esophagus and provided with an inlet in one end for stomach fluids and an outlet in its opposite end for connection to a suction machine, a separate acoustic tube encircling a portion of the suction tube with space between them, the acoustic tube having an inner end sealed to the suction tube in a location adjacent to but spaced from the inlet end thereof, the outer end of the acoustic tube being provided with an opening through which the suction tube emerges, the outer end of the acoustic tube also having an outlet for connection to a sound-monitoring device, the inner end portion of the acoustic tube having lateral openings therein, a diaphragm sleeve encircling said inner portion of the acoustic tube, the opposite ends of the sleeve being sealed to the acoustic tube with said lateral openings between the sleeve ends, a plurality of spaced electrode bands encircling the acoustic tube adjacent said diaphragm sleeve, and a wire connected to each band and extending outwardly along the acoustic tube and away from its outer end portion for connection to a heart-monitoring machine.
Claim 2
Dependent Claim 204 words
A multipurpose esophageal instrument for integrated monitoring of a patient''s physical condition, comprising a suction tube for insertion in a patient''s esophagus and provided with an inlet in one end for stomach fluids and an outlet in its opposite end for connection to a suction machine, a separate acoustic tube encircling a portion of the suction tube with space between them, the acoustic tube having an inner end sealed to the suction tube in a location adjacent to but spaced from the inlet end thereof, the outer end of the acoustic tube being provided with an opening through which the suction tube emerges, the outer end of the acoustic tube also having an outlet for connection to a sound-monitoring device, the inner end portion of the acoustic tube having lateral openings therein, a diaphragm sleeve encircling said inner portion of the acoustic tube, the opposite ends of the sleeve being sealed to the acoustic tube with said lateral openings between the sleeve ends, a plurality of spaced electrode bands encircling the acoustic tube adjacent said diaphragm sleeve, and a wire connected to each band and extending outwardly along the acoustic tube and away from its outer end portion for connection to a heart-monitoring machine.
Claim 3
Dependent Claim 60 words
A multipurpose esophageal instrument according to claim 1, in which said opening in the acoustic tube for emergence of the suction tube is in the side wall of the acoustic tube, the suction tube snugly engages the wall of said opening, and a coupling is connected to the outer end of the acoustic tube for connection to a sound-monitoring device.
Claim 4
Dependent Claim 50 words
A multipurpose esophageal instrument according to clAim 2, in which there are three of said electrode bands and three of said wires, one band being located close to each end of said diaphragm sleeve, and the third band being spaced outwardly along the acoustic tube from the other two bands.
