Technical Field
The utility model belongs to the technical field of veterinary medical equipment, and particularly relates to a visual laryngoscope for a pig anesthetic intubation.
Background
In recent years, as general animal experiments have been increasingly conducted, the demand for swine requiring tracheal intubation has increased. The oral cavity and the throat of the pig are different from those of a human body, the space is long and narrow, the tongue body is thick, the opening degree is poor, the epiglottis generally sags and curls, most of the epiglottis need to be kept for autonomous respiratory intubation, the trachea intubation difficulty is increased due to the incapability of matching, and the like. Under the prior common laryngoscope lens, an anaesthetist needs a plurality of assistants to help to separate the upper jaw and the lower jaw, pull out the tongue, fix the pig body and the like, and simultaneously use the lengthened laryngoscope lens to open the epiglottis. Often, as the face orientation of pigs is different from that of human beings, an anaesthetist needs to adopt an extremely low-position intubation posture, and the difficulty of exposing the glottis is greatly increased. Meanwhile, when the catheter is inserted, the face of an anesthesiologist faces the oral cavity and the throat of the pig, and secretion of the anesthesiologist splashes out, so that the risk of cross infection is increased. Therefore, the anesthesiologist is physically and mentally devastated, and also undertakes the ending of intubation failure, animal life risk, experiment failure and the like.
A visual laryngoscope is a visual intubation system that has been widely used in clinics in recent years. Generally consists of a display screen, a laryngoscope handle and a laryngoscope lens.
