An experimental device for mouse tracheal intubation

Abstract

The invention discloses an experimental device for mouse tracheal intubation, including a fixing bracket, limb fixing members and a head fixing member arranged on the fixing bracket, and a light source device, the fixing frame is provided with an adjustable bracket for mounting the light source device, the adjustable bracket is used for adjusting the light source device to the position of the mouse neck, A support frame include a placing surface inclined with respect to that ground surface, A limb fasten and a head fastener are arrange on that placement surface, the head fixing member is an elastic rope, the elastic rope is used for fixing the mouse maxillary incisor, and a tongue clamper is also arranged on the fixing frame. The tongue clamper is provided with an elastic connecting rope,and the other end of the connecting rope is connected with the fixing frame. The tongue clamper is used for clamping the mouse tongue. The device provided by the invention can better fix the mouse, play an auxiliary effect, and quickly expose the mouse glottis.

Description

technical field [0001] The invention relates to the field of experimental equipment, and more particularly to an experimental device for mouse tracheal intubation. Background technique [0002] With the needs of medical research, ventilator-assisted ventilation technology is increasingly applied to the research of medical experimental animal models, and rapid and effective tracheal intubation is one of the keys to the application of ventilator-assisted ventilation technology. Rats and mice are currently the most widely used experimental animals. The current methods of orotracheal intubation in mice and mice mainly include tracheotomy intubation, blind intubation, intubation under direct vision, and endoscope-assisted intubation. In particular, the frequency of intubation under direct vision is high, and the intubation method under direct vision has the advantages of high success rate and no trauma. The operator uses a high-power incandescent light bulb or a cold light sour...

Problems solved by technology

[0003] In the existing experimental process, the mice were placed flat on the table during intubation, the light through the neck was provided by a hand-held flashlight, and the mouth of the mouse was opened to find the glottis, but according to the existing In the experimental method, the mouse cannot expose the glottis well due to the mouse lying on its back on the table. In the prior art, there is no suitable fixing device for fixing the mouse, and the distance of the light source has a great influence on the exposure of the mouse glottis. The impact of the operation makes the controllability of the operation process small, and the experimental process requires skilled operation techniques
