Abstract

A subglottic suctioning system with a tracheal tube (10) having a ventilation lumen, a cuff inflation lumen (14), and a suction lumen (16) are disclosed which may help reduce the incidence of ventilator associated (or acquired) pneumonia. The suction lumen communicates with the space in the trachea above the cuff (22) where secretions accumulate. The suction lumen has a valve (36) on the proximal end for connection to a source of vacuum. The valve is adapted to interrupt the supply of vacuum to the suction lumen to allow for the introduction of a rinsing fluid in its place and to automatically re-establish the connection to the source of vacuum upon completion of rinsing. The rinsing fluid aids in maintaining an open suction lumen and may include medicaments and mucolytic agents to enhance or promote healing or to alter the properties of the mucus to make removal easier. The user may easily and repeatedly alternate suction and rinsing fluid through the suction lumen, i.e., the user may 'pulse' the line to loosen, break up and remove secretions and deposits that may partially or completely block or clog the suction lumen.

Description

Background technique [0001] Endotracheal intubation involves inserting a hollow tubular member called an endotracheal tube into the patient's windpipe. The catheter can be inserted through the mouth or less ideally through the nose or can be inserted through the neck through an incision in the front of the throat. If the tube is inserted through the mouth or nose, it is called an endotracheal tube, and if the tube is inserted through the front of the throat, it is called a tracheostomy tube or endotracheal tube. Both types of tubes are referred to herein as endotracheal tubes. The endotracheal tube enters the trachea and terminates at a location above the carina, anterior to a location between the second and fourth thoracic vertebrae. Gas can then be introduced through the central lumen of the endotracheal tube and into the patient's lungs. [0002] The fundamental purpose of endotracheal intubation is to mechanically ventilate the patient's lungs when the patient is unable...
