Manual tracheotomy tube with antibacterial nano material coating
InactiveCN101653635AAvoid enteringAchieve antibacterial effectTracheal tubesCatheterTracheotomyEngineering
The invention relates to the technical field of medical apparatus. The generation of ventilator-associated pneumonia is the result of the inspiration of secretion with pathogen, wherein the bacterialcontamination in a ventilator air tube is also a principal element for causing the ventilator-associated pneumonia. The invention aims to provide a manual tracheotomy tube with broad spectrum of antimicrobial activity and controllable slow-release medicaments, comprising a flexible tube body and a tampon system attached to the outside of the tube body, wherein the inner surface and the outer surface of the tracheotomy tube are combined with macromolecular polymer antimicrobial coatings in which medicaments with pharmacologic effect are loaded. The invention not only achieves the efficacy of providing air paths for a traditional tracheotomy tube and keeping the respiratory tract smooth, but also has excellent bacteriostatic effect and the slow release effect of the controllable medicaments,thereby providing a wide application prospect for clinical application of the manual tracheotomy tube.
