Description

A new type of children's tracheal intubation

technical field

The utility model relates to the technical field of medical devices, in particular to a novel tracheal intubation tube for children.

Background technique

Tracheal intubation in children refers to the technique of inserting a special endotracheal tube through the oral cavity or nasal cavity and inserting it into the trachea or bronchus through the glottis. Administration (such as epinephrine injection in emergency, pulmonary surfactant, etc.) provides the best conditions.

At present, there are the following problems in the use of tracheal intubation in the pediatric department of the hospital: 1. Infants and young children have delicate glottis and rich blood circulation. The balloon at the front end of the existing tracheal intubation protrudes from the outer wall of the tracheal intubation in a shriveled state. The air bag protruding from the outer wall of the tracheal intubation is easy to damage the glottis. After the glottis is injured (even a slight injury), it will cause postoperative hoarseness, pain in the throat when swallowing, and tightness in the larynx. 2. Difficulty in tracheal intubation, especially When there is spontaneous breathing, children's glottis is narrow; 3. Due to the soft texture of tracheal intubation, it is necessary to rely on copper wire to insert the tracheal intubation tube to bend the tracheal intubation tube into an arc suitable for insertion. The guide wire of tracheal intubation is mostly thin copper wire, which is used repeatedly in sterile tracheal intubation. Incomplete disinfection can easily lead to cross-infection; 4. After the intubation is completed, it is necessary to confirm whether the tracheal intubation enters the trachea. At present, breathing through auscultation is performed. However, it is inconvenient to be forced to stop chest compression when performing chest compression during resuscitation.
