Description

Fully-wrapped laryngoscope and laryngoscope lens

Technical Field

The invention relates to the technical field of medical instruments, in particular to a fully-wrapped laryngoscope and a laryngoscope lens.

Background

Laryngoscopes are one type of endoscope used in the field of medical devices and are commonly used to guide endotracheal intubation. Traditional laryngoscope does not have image system, and when the doctor used, need closely carry out the intubate through the visual observation glottis with closely, this kind of laryngoscope uses inconveniently, and the doctor need closely contact the patient moreover, has increaseed the risk that the doctor infects. Modern video laryngoscopes have an image system, and doctors can perform tracheal intubation through images displayed by the laryngoscope, so that the laryngoscope is convenient to use and does not need to be in close contact with patients. Laryngoscope in the latter context is referred to as video laryngoscope.

The laryngoscope blade is divided into a half-wrapping type laryngoscope blade and a full-wrapping type laryngoscope blade, the half-wrapping type laryngoscope blade can not wrap a laryngoscope handle, and the full-wrapping type laryngoscope blade can wrap the laryngoscope handle part completely. Because the oral cavity sizes of neonates, infants and adults are different, the laryngoscope lens has various specifications, and the lengths of the holding part, the bending part and the tongue pressing part of the laryngoscope lens with different specifications are different so as to adapt to the oral cavity sizes of different people.
