AI Technical Summary
Conventional laryngoscope blades made of rigid metal cause injuries to teeth, mucous membranes, or the trachea during endotracheal intubation, leading to complications such as bleeding and swelling.
A laryngoscope blade with an elastic protective layer made of medical rubber or silicone is integrated into the rear area of the spatula to act as a buffer, reducing pressure on sensitive tissues and preventing injuries.
The elastic layer minimizes tooth chipping and mucosal injuries while maintaining stability during tube insertion, and is easy to clean or produce for single-use products.

Abstract
Description
1. Title
[0001] Laryngoscope blade with elastic protective backing for injury prevention 2. Description
[0002] The present development concerns a laryngoscope, in particular the spatula part used in endotracheal intubation.
[0003] Conventional laryngoscope blades are made entirely of rigid metal. Inserting the tube often results in injuries to teeth, mucous membranes, or the trachea. This can lead to bleeding, swelling, or complications during anesthesia.
[0004] The further development therefore provides that the rear area of the spatula (5) is provided with an elastic protective layer made of medical rubber or silicone. • This flexible layer acts as a buffer between the metal spatula and the sensitive tissue structures. • It reduces pressure on the teeth and prevents chipping. • It minimizes the risk of mucosal injuries. • The protective layer is firmly bonded to the spatula, easy to clean, or inexpensive to produce in the case of single-use products.
[0005] Furthermore, the elastic surface can be designed to be non-slip in order to increase stability when inserting the tube.
[0006] This further development thus combines the stability of the classic metal spatula with the safety of a soft protective surface. 3.
