Description

Technical Field

[0001] The invention relates to the technical field of rat tracheal intubation, in particular to a visual tracheal intubation device for rats. Background Art

[0002] Rat tracheal intubation technology is a prerequisite for animal experiments such as thoracotomy, respiratory function testing and intratracheal drug administration. Smooth and stable completion of tracheal intubation and reduction of related injuries during tracheal intubation can lay a good foundation for subsequent experiments. Currently, the commonly used methods of tracheal intubation are: invasive tracheal intubation and non-invasive tracheal intubation (blind intubation, oral intubation and neck fluoroscopic intubation, etc.).

[0003] Invasive tracheal intubation: fix the anesthetized rat, prepare the neck skin, place your fingers on the throat skin to touch the trachea, make a 10mm small incision on the ventral side of the midline of the neck, and use a sharp blade to dissect the tissue plane to show the trachea. Use a sharp knife to make a 1mm small opening in the front of the trachea, and gently insert the catheter along the direction of the trachea to complete the operation.

[0004] Blind intubation method: The anesthetized rat is fixed on the animal experimental table in a supine position, and the upper incisors of the rat are fixed with silk thread to pull back and fix the head. Then, the tongue of the rat is clamped by toothless forceps in the left hand and pulled out of the mouth from the left corner. At this time, the right hand performs the tracheal intubation operation. The feeling of successful intubation is that there is a slight resistance when the tube passes through the vocal cords and enters the trachea, but there is no such resistance when entering the esophagus.

[0005] Oral intubation with direct vision: The rat is anesthetized and fixed, and a strong light source is used to illuminate the rat's mouth. The rat's throat can be seen directly. The endotracheal tube is passed through the guide wire through the glottis and then the guide wire is withdrawn.

[0006] Transcervical intubation method: This method is to place a high-intensity cold light source on the ventral surface of the neck to transmit light to the rat's neck, use forceps to gently pull the tongue upward to the side of the lower teeth, and place the flat inner surface of one side of the forceps on the lower end of the tongue. The light from the high-intensity cold light source can illuminate the rat's throat through the skin and muscles of the rat's mandible, and can clearly see the rat's airway opening and closing as the rat breathes. At this time, the tracheal tube can be inserted into the airway during the rat's inspiratory phase.

[0007] Video laryngoscope-assisted method: pull the rat's tongue to the side of the lower teeth, insert the video laryngoscope, lift the rat's epiglottis, clearly expose the rat's glottis, and insert the endotracheal tube into the glottis under the guidance of the video laryngoscope.

[0008] Invasive endotracheal intubation can cause damage to the rat's neck, while blind intubation, oral intubation, transcervical intubation and video laryngoscope-assisted intubation all require a lot of endotracheal intubation experience. Novice operators may need to perform repeated intubation due to lack of experience. Repeated intubation can easily cause complications such as laryngeal spasm, laryngeal edema, tracheal perforation, bleeding and excessive secretions blocking the trachea leading to suffocation. Summary of the invention

[0009] The purpose of the present invention is to provide a visual tracheal intubation device for rats to solve the problem that the invasive tracheal intubation method proposed in the above-mentioned background technology will cause damage to the neck of the rat, and the blind intubation method, the oral visual intubation method, the transcervical transillumination intubation method and the visual laryngoscope-assisted method all require a lot of tracheal intubation experience.
