Description
Technical field
This utility model belongs to medical instruments field, particularly relates to a kind of laryngoscope.
Background technology
Doctor, when carrying out endotracheal intubation, needs to use laryngoscope usually.Laryngoscope in use, can be close to and detest portion and then carry out tracheal intubation operation, because laryngoscope blade is hard metal material, detests portion's mucosal bleeding so easily cause by laryngoscope blade, and each use before and after all need cleaning, otherwise easily cause infection.In addition, the laryngoscope blade entirety of common laryngoscope has the arc of human body oral cavity and throat physiological camber when natural position, so after laryngoscope blade extend into the oral cavity of patient, if the larynx anatomical position of patient is higher, bottleneck throat neoplasm, oral cavity are darker, doctor can be caused to be difficult to the tracheostomy of direct viewing to patient, so people have invented video laryngoscope, a photographic head can be set in the front end of laryngoscope blade simultaneously.But owing in human body being humidity and having uniform temperature, so often can mist be tied on photographic head, have a strong impact on the normal operating of doctor.Meanwhile, when saliva in disease population, sputum are more, the field of view of doctor can also be affected.If saliva, sputum enter upper respiratory tract, patient also can be caused to choke and to cough.Therefore be necessary to improve existing laryngoscope.
Utility model content
One or more in order to what solve the problem, this utility model provides a kind of laryngoscope.
According to an aspect of the present utility model, a kind of laryngoscope is provided, comprise hands handle, laryngoscope blade and the transparent protective sleeve of elasticity, protective sleeve one end is provided with elastic banding edge, laryngoscope blade is camber structure, protective sleeve and laryngoscope blade match, protective sleeve is placed on outside laryngoscope blade, the root of laryngoscope blade and the bottom-hinged of handle, the front end of laryngoscope blade is provided with photographic head and groove, luminescent device is provided with near photographic head, photographic head is positioned at groove, photographic head is connected with external device communication, protective sleeve with offer the first through hole, first through hole is corresponding with the position of photographic head and luminescent device.Its beneficial effect is: arranging of the protective sleeve that elasticity is transparent can effectively prevent laryngoscope blade to the damage detesting portion; transparent protective sleeve is provided with the first through hole; first through hole is corresponding with the position of photographic head and luminescent device; photographic head and luminescent device can not be blocked, thus the result of use of laryngoscope can not be affected.Removed by protective sleeve etc. after tracheal intubation, structure is simple, easy to use.
