Visual laryngoscope for pig anesthesia intubation

Abstract

The invention discloses a visual laryngoscope for a pig anesthesia cannula. The visual laryngoscope comprises a laryngoscope handle, a laryngoscope lens and a display screen; the laryngoscope lens is arranged at the lower part of the laryngoscope handle, and the display screen is located above the laryngoscope handle; a storage cavity is formed in the laryngoscope handle, a controller and a lithium battery are arranged in the storage cavity, and the controller and the lithium battery are connected with the laryngoscope lens and the display screen through circuits; a square-tube-shaped cavity is formed at the lower part of the laryngoscope lens, and a cavity adjusting assembly capable of adjusting the cavity to stretch out and draw back is arranged in the cavity; the inner side of the tail end of the cavity adjusting assembly is provided with an adjustable telescopic tongue pressing piece; tooth protection grooves are formed in two sides of the near end of the laryngoscope lens; and a device for fixing a pig tongue is arranged on the left side of the near end of the laryngoscope lens. The visual laryngoscope is applied to the difficult airway of a pig, meanwhile, teeth and a tongue can be fixed at the near end of the laryngoscope lens, a far-end bidirectional adjusting mechanism is suitable for pigs of different body types, the occurrence rate of the difficult airway of an experimental animal is greatly reduced, meanwhile, manpower and material resources are saved, and scientific research and teaching are more convenient.

Description

technical field [0001] The invention belongs to the technical field of veterinary medical equipment, in particular to a video laryngoscope for pig anesthesia intubation. Background technique [0002] In recent years, the demand for pigs requiring endotracheal intubation has also increased due to the increasing use of large-scale animal experiments. The mouth and throat of pigs are different from those of humans. The space is narrow and long, the tongue is thick, the mouth opening is not good, the epiglottis is generally drooping and curled, most of them need to keep the spontaneous breathing intubation, and they cannot cooperate, which all increase the difficulty of tracheal intubation. In the past, under ordinary laryngoscopes, the anesthetist needed a few assistants to help separate the upper and lower jaws, pull out the tongue, and fix the pig's body, etc. Often because the face orientation of pigs is different from that of humans, anesthesiologists need to adopt a very ...
