AI Technical Summary
During endotracheal intubation anesthesia, loose teeth are prone to falling out due to collisions with anesthesia intubation equipment or surgical instruments. Although existing shrinkable pouch devices can prevent loose teeth from "escaping," they cannot mitigate the impact of collisions, posing a risk of tooth loss.
A pouch device was designed, made of deformable rubber material, with a miniature inflation valve and a ring-shaped pull cord. The pouch can expand to buffer impact forces and is fixed to the gums by front and rear air flaps to improve stability.
It effectively prevents loose teeth from falling out, reduces tooth loss due to impact, and improves the protection of teeth during surgery.
