Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be embodied in many other forms without departing from the spirit or essential characteristics thereof, and it should be understood that the invention is not limited to the specific embodiments disclosed below.

Example 1

As shown in fig. 1-3, a mouse trachea cannula includes a cannula body 1, a connector 2 and a guide core 3. Intubation body 1 adopts the PICC pipe, and its one end and connector 2 threaded connection, the other end are equipped with the variable diameter portion 101 that the internal diameter reduces gradually.
