Balloon-tipped catheter, especially an endotracheal catheter

摘要

The invention relates to balloon-tipped catheters, especially endotracheal catheters, having a catheter tube made of an elastic, tissue-compatible material in which, according to Figure 1, the control balloon (6) is located on the catheter tube (1) in the vicinity of the proximal end (3) of the catheter tube (1) and is firmly connected to the latter, at least one supply tube (5) which connects the control balloon (6) with the blocker cuff (4) being located over the entire length in or outside the wall of the ventilation tube (1), the supply tube (5) being connectable to a connecting piece (13) for a blocker syringe on the proximal end (3) of the tube (1) and having one or more openings (8) and (9) in the region of the blocker cuff (4) and the control balloon (6). The supply tube (5) can also be formed (Figure 4) by one or more grooves (14) in the outer wall of the ventilation tube (1) and a foil tube (15) covering the grooves towards the outside so as to be gas-tight and liquid-tight. <IMAGE>
