Description

Depth-adjustable nasal/oral preformed tracheal cannula

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a depth-adjustable nasal/oral preformed trachea cannula.

Background

In order to facilitate the surgical operation and to reserve the surgical space, nasal/oral preformed endotracheal tubes are currently commonly used during general anesthesia in oromaxillofacial surgery. However, the shape and the length of the trachea cannula are fixed and cannot be adjusted, so that the depth of the trachea cannula can not be changed in clinical use. In view of the difference of the depth from the nostril/oral lip to the glottis of the patient, certain potential safety hazards exist when the trachea cannula is placed at a fixed depth, and especially when the placement depth is insufficient, the trachea cannula is easily removed or the trachea cannula cuff presses the glottis to cause damage.

The nasal/oral preformed trachea cannula material commonly used at present is hard plastic, the bending part can not change shape, the cannula is fixed outside the nostril/outside the mouth after success, and meanwhile, the depth of the cannula is fixed and can not be adjusted.

Because patient's height, cervical vertebra length, glottis position are different, and there is very big individual difference in incisor to glottis distance, fixed meaning that the intubate degree of depth of different patients' trachea cannula bend department is fixed. For patients with longer incisor-glottis distance, the tracheal cannula is not long enough, and the patient can be accidentally removed from the tube or the cuff can press the glottis to cause damage; for patients with short incisor glottis distances, the endotracheal tube may be too deep into one side bronchi.
