Illumination cannula device for small animal

Abstract

The invention discloses an illumination cannula device for a small animal, which comprises an LED (Light-Emitting Diode) light source, wherein the front end of the LED light source is connected with a light-guide fiber joint; the front end of the light-guide fiber joint is connected with a light-guide fiber; an optical fiber stabilizing device, a three-way tube and a trachea cannula which are connected with one another are sleeved in sequence at positions close to the front tail end of the light-guide fiber from back to front; the three-way tube is laterally connected with an injector which is communicated with the trachea cannula; and the front tail end of the light-guide fiber is accommodated in the trachea cannula. The illumination cannula device for the small animal disclosed by the invention has the advantages of smaller damages to the tracheae of animals, realization of high animal survival rate, wide view field, sufficient light rays and higher accuracy of insertion of the hose into the trachea cannula.

Description

technical field [0001] The invention relates to a viscera expansion device, in particular to a small animal lighting type intubation device. Background technique [0002] At present, tracheal intubation of small animals mainly adopts the following two methods: 1. invasive tracheal intubation (tracheotomy); 2. non-invasive tracheal intubation. Among them, although invasive tracheal intubation is easy to operate, it is traumatic, and animals generally cannot survive after tracheal intubation, so it is not suitable for studying the process of disease. In contrast, non-invasive endotracheal intubation is less invasive, more useful, and has a higher postoperative survival rate. Non-invasive endotracheal intubation can be divided into two types: blind endotracheal intubation using a gastric feeding tube and endotracheal intubation under a small animal laryngoscope. When using a gastric feeding tube for blind tracheal intubation, because it is blind intubation, the trachea of ​​s...

AI Technical Summary

Problems solved by technology

When using a gastric feeding tube for blind tracheal intubation, because it is a blind intubation, the trachea of ​​small animals is greatly damaged. Often, the intubation fails for a long time, resulting in the death of the animal, which increases the cost of the experiment and affects the progress of the experiment.

When performing endotracheal intubation under a small animal laryngoscope, because the animal is often accompanied by a large amount of secretions during endotracheal intubation, which affects the endotracheal intubation, the most important problem is that when passing through the epiglottis, the hose often blocks The light source reduces the accuracy of the tube entering the trachea; and so far, all intubation devices have separated the light source from the guide wire, causing most of the oral cavity or throat space of small animals to be occupied by various tubes, resulting in insufficient vision
