AI Technical Summary

Technical Problem

Existing endotracheal tubes with fixed cuffs pose risks of tracheal tissue damage and complications due to unavoidable contact with pathologically altered tracheal segments, leading to potential perforation, malposition, and life-threatening air leaks.

Method used

A blockable endotracheal tube with longitudinally displaceable inflatable cuffs that can be positioned optimally relative to healthy tracheal tissue, allowing adjustable pressure distribution to avoid damaged areas during ventilation.

Benefits of technology

Prevents tracheal tissue stress and potential perforation by ensuring cuffs are positioned over healthy tissue, reducing the risk of complications and optimizing ventilation.

Abstract

A closable endotracheal tube for ventilating a patient, comprising a tube (1) and one or more inflatable cuffs (2) attached to the tube (1) to form a seal on the trachea (7) surrounding the endotracheal tube during ventilation, characterized in that the tube (1) is arranged with its tracheal end region so as to be coaxially displaceable inside a sheath tube (4) made of a soft elastic material, wherein an annular stiffening element (5) is attached to or incorporated into the outer surface of the tracheal end region of the tube (1), and wherein the cuff (2) arranged inside the sheath tube (4) surrounds the region of the tube (1) provided with the stiffening element (5), wherein the cuff (2) is closed on the endotracheal tube by controlled axial displacement of the tube (1) within the sheath tube (4). can be positioned in a length-shifting manner,wherein the block cuff (2) after its positioning and subsequent inflation presses symmetrically around its circumference against the sheath tube (4).
