Pervak's antireflexive endotracheal tube relates to medicine, namely to devices and instruments for injecting medical preparations into organism, in particular, to endotracheal tubes. The Pervak's antireflexive endotracheal tube enables to reduce a risk of toxic responses of the human organism when using such highly toxic drugs during intubation of trachea as local anesthetics, subject to a way for the reduction of pathophysiological responses of the human organism to a necessary extent. The endotracheal tube (1) includes a body (2) with a proximal end (3) and a distal end (4), an inflatable cuff (5) placed on the distal end (4) of the body (2) of the endotracheal tube (1), a catheter (6) of the inflatable cuff (5) and a device for drug irrigation made as a catheter (7) for supply of drugs, a lateral ring duct (8) of the body (2) of the endotracheal tube (1), a lateral ring duct (9) of the inflatable cuff (5) and a longitudinal duct (10). In the outer wall of the lateral ring duct (8) of the body (2) of the endotracheal tube (1) there are through holes (11). In the outer wall of the lateral ring duct (9) of the inflatable cuff (5) there are through holes (12). The lateral duct (10) links a cavity of the lateral ring duct (8) of the body (2) of the endotracheal tube (1) with a cavity of the lateral ring duct (9) of the inflatable cuff (5). |
