Problems solved by technology

[0002] Because the airway of the mouse is very narrow and there is an esophagus at the back end, the current popular tracheal intubation operation is to perform tracheotomy and intubation under anesthesia, so the trauma and bleeding of the operation directly affect the success and safety of the experiment. stability of results
[0003] If direct non-invasive intubation is performed, it is not easy to perform the operation without anesthesia in animals
Even with anesthesia operation, intubation is easy to enter the esophagus by mistake, resulting in drug administration failure and seriously affecting the experimental results

Abstract

The invention discloses a mouse non-invasive trachea intubation instrument. The instrument comprises a pressure probe communicated with a pressure amplification device, the pressure amplification device is connected with a pressure sensor, the output end of the pressure sensor is connected with an input end of an amplification circuit, and the output end of the amplification circuit is connected with an indication device. The trachea intubation instrument can distinguish the airway from the esophagus of a mouse, and accordingly airway intubation operation is indicated.

Description

Technical field [0001] The invention relates to the field of biomedicine, in particular to a mouse non-invasive tracheal intubation instrument. Background technique [0002] Because the airway of the mouse is very narrow and there is an esophagus at the back end, the current popular tracheal intubation operations are tracheotomy and intubation under anesthesia. In this way, the impact of surgical trauma and bleeding on the mice directly affects the success of the experiment. The stability of the results. [0003] If direct intubation is performed noninvasively, it is not easy to perform the operation when the animal is not anesthetized. Even if anesthesia is performed, the intubation tube can easily enter the esophagus by mistake, causing drug delivery failure and seriously affecting the experimental results. Summary of the invention [0004] The invention aims to provide a mouse non-invasive tracheal intubation instrument, which can distinguish the airway and esophagus of the mou...
