Problems solved by technology

The existing endotracheal intubation has low hydrophilicity, and auxiliary items such as lubricants need to be applied when inserting, which increases the difficulty of intubation and increases the pain of the patient. Cause secondary harm to patients, especially the endotracheal intubation needs to be inserted through the nasal cavity. Since the nasal cavity is very sensitive and belongs to the respiratory passage, there are higher requirements for comfort and antibacterial properties

Abstract

The invention relates to the technical field of a medical instrument, and discloses a super-hydrophilic antibacterial trachea cannula. The super-hydrophilic antibacterial trachea cannula comprises a trachea cannula insertion section and a connecting tube communicated with the trachea cannula insertion section; the surface of the trachea cannula insertion section is coated with a super-hydrophilic antibacterial coating; the super-hydrophilic antibacterial coating comprises high-molecular polymers or monomers with hydrophilic groups, nano silver ions or chitin and coating solution with solid content of 5% to 25%. The super-hydrophilic antibacterial trachea cannula has excellent hydrophilic performance and antibacterial property, and meanwhile, is non-toxic and harmless; intubation difficulty is reduced; pain of a patient is reduced; bacterial infection of the patient is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a superhydrophilic antibacterial tracheal intubation tube. Background technique [0002] Endotracheal intubation is a commonly used insertion medical device. Since it needs to be inserted into the patient's body, it has high requirements for the softness and comfort of its surface. The existing endotracheal intubation has low hydrophilicity, and auxiliary items such as lubricants need to be applied when inserting, which increases the difficulty of intubation and increases the pain of the patient. It causes secondary harm to patients, especially the endotracheal intubation needs to be inserted through the nasal cavity. Since the nasal cavity is very sensitive and belongs to the respiratory passage, there are higher requirements for comfort and antibacterial properties. [0003] Therefore, researching a super-hydrophilic antibacterial tracheal intubation to improve the com...
