Description

A kind of New-type laryngoscope blade

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of novel laryngoscope blade.

Background technology

In the time rescuing the patients such as respiratory failure, respiratory arrest, often needing to insert tracheal intubation rescues, normally operate by laryngoscope, secretions in patient's mouth can drench laryngoscope, and affect the definition of camera lens, affect correct intubate, bring certain impact to rescue patient's life.If laryngoscope time sterilization is not thorough in use, the virus between patient is easily cross infection, makes patient likely suffer from new disease; And in use, most cases is that eyeglass part is carried out disinfection, but because operating grip intracavity is equiped with battery, so generally operating grip is not well sterilized.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of New-type laryngoscope blade that guarantees laryngoscope definition.

The technical solution of the utility model is as follows:
