摘要： A monitoring catheter that inserts into the patient's esophagus alone or in combination with an existing catheter, such as a feeding or aspiration tube. The monitoring catheter includes a pair of EMG electrodes on an exposed surface that contact the patient's esophageal wall to measure the activity of the diaphragm and/or a pair of pressure detecting mechanisms that measure the pressures within the patient at separate locations. The electrodes are sized and spaced from one another so as to maximize detection of diaphragm muscle activity while minimizing detection of noise. The pressure detecting mechanisms are sized and spaced apart to measure the patient's esophageal and gastric pressures, for example. If necessary, an attaching mechanism secures at least a portion of the monitoring catheter to the existing catheter so that the monitoring catheter uses the existing catheter as a tracking guide.

摘要： A coupling structure for placing a stethoscope and an endotracheal tube in gaseous communication, thus allowing an attending medical professional an enhanced ability to hear the breathing sounds of a patient in order to aid the medical profession to perform a nasal endotracheal intubation procedure while also providing the medical professional increased range of motion and protection from airborne pathogens and potentially dangerous bodily fluids, is described. A resonating membrane is positioned between the ends of the stethoscope and endotrachael tube to prevent air borne pathogens form passing into the stethoscope.

摘要： A blood oxygen saturation sensor or oximeter is mounted to a probe for insertion into the esophagus of a patient. The sensor includes a set of optical transmission elements and an optical detector for optically detecting the blood oxygen saturation of tissues of the esophagus. By mounting the blood oxygen saturation sensor to a probe for insertion into the esophagus, blood oxygen saturation measurements are obtainable at a physiologically stable site which is fully isolated from ambient light external to the patient. The probe for insertion into the esophagus may additionally be provided with a heart and respiration sound sensor and a temperature sensor. With such a combination, a single probe provides the detection of several useful physiological parameters, including temperature, heart, and respiration sounds and blood oxygen saturation levels. The esophageal probe is reliably and inexpensively constructed of few components and is ideally suited for one-time use.

摘要： An esophageal gastric apparatus includes a first elongated tube with forward and rearward ends, and a second tube inserted within the first tube with the forward end of the second tube projecting from the forward end of the first tube. The rearward end of the second tube projects outwardly through the wall of the first tube adjacent the rearward end of the first tube. The second tube has an outside diameter less than the interior diameter of the first tube, so as to form a cavity between the second tube and the first tube. A plurality of apertures are formed in forward end of the first tube, with a diaphragm surrounding the apertures, so as to transmit sound through the first tube to the rearward end thereof. The second tube has suction ports formed in the forward end thereof to suction fluid and material therethrough.

摘要： A heart-sound monitor and esophageal stethoscope which makes use of fluidicaminar proportional amplifiers (LPAs). These LPA's are used to sense and amplify incoming acoustic pressure signals, such as heart signals. Moreover, the fluidic monitor is able to monitor a fetus heartbeat while eliminating the acoustic interference present from the mother's heartbeat. In this case, the LPA acts not only as an amplifier, but as an acoustic filter as well.

摘要： A flexible endotracheal tube is disclosed for acoustically monitoring the heart sounds of a patient. The tube comprises a flexible conduit to provide a respiratory passage and a separate cardiac sound passage conduit. An inflatable cuff is disposed near the distal end of the flexible conduit to contact and sealingly conform to the interior wall of the trachea upon inflation. The closed chamber of the inflatable cuff is in fluid communication with the separate sound passage for enhanced acoustic reception from the inflatable cuff. The distal end of the sound passage conduit includes a terminal end defining an angular cut to enhance the acoustic reception of the heart sounds acoustically transmitted from the interior tracheal wall through the inflatable cuff and into the acoustically separate conduit. The sound conduit extends longitudinally with the respiratory conduit and is constructed within an enlarged wall forming one side of the respiratory conduit to provide a figure eight configuration in cross section such that the two conduits mean are acoustically separate from each other but contained within the same endotracheal tube. A means for permitting the pressurizing of the sound conduit and a means for permitting the monitoring of pressure variations within the conduit is also disclosed.

摘要： Disclosed are methods and apparatus for the detection of inadvertent endobronchial intubation, esophageal intubation and other potentially dangerous complications arising from invasive monitoring, endotracheal intubation and mechanical ventilation during surgery. Methods of the present invention generally require producing a mixed electrial signal comprising the combination of a first electrical signal and a second electrical signal, the first electrical signal being representative of the sounds emanating from a first region of the patients body and the second electrical signal being representative of the sounds emanating from a second region of the patients body. The mixed electrical signal is converted into a display signal, and then the display signal is monitored while reducing the contribution of said first electrical signal in said mixed signal to a value substantialy less than the contribution of said second signal in said mixed signal.Apparatus comprising at least two electronic sound sensing devices are disclosed. Means for independently and adjustably amplifying the electrical signals are provided. The apparatus further includes means for mixing said amplified electrical signals to produce a mixed electrical signal. The output of the mixing means is connected to a signal transducer for converting said mixed electrical signal into a display signal.

摘要： An esophageal stethoscope includes a plastic tube having at least one bore extending over the length of the tube. The tube has a distal end which is insertable into the esophagus of the patient, and a proximal end for providing respiratory and heart sounds produced at the distal end and transmitted through the tube for monitoring. A microphone element is mounted in the bore of the tube at the distal end for detecting the respiratory and heart sounds, and providing corresponding electrical signals. The signals are conducted through wires arranged in the tube bore to the proximal end of the tube where the wires are connected to a terminal member. Accordingly, the heart and respiratory sounds can be reproduced with maximal signal to noise ratio when the terminal member is connected to a suitable amplifier and speaker arrangement, or other signal processing equipment.
