Abstract: A device for unblocking intubation tubes in intubated patients and tracheotomy cannulas in tracheotomized patients comprises two elements which are introduced into the intubation tube or tracheotomy cannula by their distal end, namely a flexible rod (1) rounded at its distal end (2) provided with a collapsible system (3) near its distal end, and provided with a projection (5) at the other end to permit manipulation, and a flexible tube (4) provide with a reference stop (6) at its proximal end, into which the rod (1) is inserted and in which it can slide. The collapsible system (3) is collapsed in the flexible tube (4) and the sliding of the central rod (1) inside the flexible tube (4) after the introduction of device into the intubation tube or into the tracheotomy cannula releases the collapsible system (3), which sweeps the tube and the tracheotomy cannula as the device is withdrawn. This device may be sterile and disposable. Its use is recommended one to four times daily.
