This invention provides an antibacterial and anti-adhesion double-balloon tracheostomy cannula and its preparation method. The invention involves constructing a coating material co-loaded with a newly developed tetradecyl antibacterial agent and chondroitin sulfate on both the cannula's surface and inner wall. This coating possesses both excellent hydrophilicity and strong antibacterial properties. The hydrophilicity makes it difficult for secretions to adhere; the antibacterial properties kill bacteria through contact, minimizing the development of drug resistance; and the anti-adhesion properties reduce the basis for biofilm formation. These three properties work synergistically to achieve full-chain protection from the "source" to the "process," significantly reducing the risk of luminal obstruction and VAP (ventilator-associated pneumonia), while also reducing the frequency of suctioning and mucosal damage, thus improving patient comfort.
