Device for unblocking intubation tubes and tracheotomy cannulas in vivo

A device for preventing, by brushing, the blocking of intubation tubes in intubated patients or of tracheotomy cannulas in tracheotomized patients, the device comprising first and second elements each having a distal end adapted to be introduced into an intubation tube or into a tracheotomy cannula, and a proximal end adapted to be controlled by an operator, said first element comprising a flexible central rod, the distal end of said rod being rounded, retractable tube/cannula cleaning means being disposed around the rod in the vicinity of the distal end thereof, said second element comprising a flexible tube in which said first element is received and slidably movable, the retractable tube/cannula cleaning means having a retracted configuration when received inside said second element and a deployed configuration when released from said second element for cooperation with walls of the intubation tube or the tracheotomy cannula, said device being adapted to be inserted by its distal end into the intubation tube or the tracheotomy cannula of the patient, said flexible tube being slidable relative to said rod to release said retractable tube/cannula cleaning means into its deployed configuration.
