An endotracheal tube cleaning apparatus 10 which can be periodically inserted into the inside of an endotracheal tube 30 to shave away mucus deposits. In a preferred embodiment, this cleaning apparatus 10 comprises a flexible central tube 12 with an inflatable balloon 40 at its distal end. Affixed to the inflatable balloon are one or more shaving rings 70, each having a squared leading edge 72 to shave away mucus accumulations 60. In operation, the uninflated cleaning apparatus 10 of the present invention is inserted into the endotracheal tube until its distal end is properly aligned with or slightly beyond the distal end of the endotracheal tube. After proper alignment, the balloon 40 is inflated by a suitable inflation device, such as a syringe 14, until the balloon's shaving rings are pressed against the inside surface of the endotracheal tube. The cleaning apparatus is then pulled out of the endotracheal tube and, in the process, the balloon's shaving rings shave off the mucus deposits from the inside of the endotracheal tube.

The present invention is directed to a novel device and method for providing a disposable endotracheal intubation device for use with an auxiliary passageway serving as a guide for the placement of an orogastic or other enterally directed device in a patient. The present invention pertains to a combination intubation device comprising an endotracheal tube and a catheter proximate the endotracheal tube to guide the path of an enteral tube. In a preferred embodiment, the endotracheal tube is capable of defining an arcuate path in a first geometric plane between its proximal end and its distal end to facilitate introduction of the tube into the trachea of a patient. In a preferred embodiment, the catheter employs a fenestration to facilitate removal of the intubation device from the patient without removal of any enteral device previously directed therethrough into the patient.

A method for endotracheal intubation allows resuscitation of the patient to continue during intubation. A curved guide having a mask and a ventilation port is inserted into the patient's mouth and upper airway. The patient is initially resuscitated by supplying a flow of air/oxygen through the mask and simultaneously applying cardiac chest compressions. An endotracheal tube is inserted over the distal end of a fiber optic probe. Resuscitation continues without interruption while the fiber optic probe and endotracheal tube are advanced along the guide into the patient's airway, thereby allowing the physician to carefully guide the fiber optic probe and endotracheal tube to a position past the larynx while resuscitation continues.

Determining the placement of an endotracheal tube in a patient. The invention evaluates discontinuities in the medium surrounding the endotracheal tube, such as the airway, as a function of distance past an end of the endotracheal tube. Using a loudspeaker to generate sound waves, the sound waves propagate through a coiled wavetube, a connecting adapter, and an endotracheal tube, into the area of interest. With a processing system, reflected sound waves which return from the cavity back to a microphone within the wavetube are analyzed and an area-distance curve of the area in interest is constructed.

This invention can be used in three different ways for patients who are lying down in bed or on the operating table. First it facilitates the endotracheal intubation, secondly it facilitates the spontaneous breathing of obese patients and thirdly it assists the spontaneous inspiration and expiration in a non-invasive way. This invention device is positioned under the patient before he is asleep without disturbing him. It allows a gradual elevation of the lower and or upper thorax, a gradual elevation of the head giving a flexion of the neck and a gradual hyperextension of the head. After intubation the position is returned to normal without need for removing the invention device. This invention elevates the spinal column and therefore the thorax is no more compressed and the ribs can move free. Inspiration requires less force and the patient can be breathing easier even when lying down. In this invention the spinal column elevation can also be inflated in a synchronized way with the respiration of the patient. During inspiration the spinal column is elevated, facilitating the inspiration. During expiration the elevation is lowered, facilitating the expiration. The work of breathing is reduced for the patient resulting in larger minute volume ventilation or less oxygen consumption.

An intra-tracheal sputum aspiration apparatus arranged so that air feeding to and air evacuation from trachea (13) by means of artificial respirator (12) are carried out through tracheal cannula (14) and so that in the event of sputum clogging, tube pump (16A) is operated to thereby attain discharge of sputum through suction tube (15) to the outside of the body by means of a negative pressure produced thereby. By virtue of the employment of the tube pump (16A) as a sputum aspirator (16), the intra-airway pressure by the artificial respirator (12) would have substantially no fluction even when a positive pressure is applied to the lungs. Consequently, sputum disposal can be accomplished while maintaining artificial artificial respiration, so that there can be prevented any secondary infection by infectious agents discharged from sputum collection bottle (17) into the air.

A tracheal cannula of the invention includes a breathing path for supplying and discharging air formed between a basal end for connection with a breathing tube extending from an external artificial respirator and a distal end for insertion into a patient's trachea, and a trachea side opening formed at the distal end of the breathing path. Besides and along the breathing path, a suction path is provided for sucking phlegm accumulated in the patient's trachea. A phlegm suction opening is formed in a region of a wall of the suction path on the side of the inner wall of the trachea between the distal end of the breathing path and a cuff, the phlegm suction opening facing the inner wall of the trachea.
