Manufacture method and use method of rat tracheal intubation equipment

The invention belongs to manufacture method and use method of rat tracheal intubation equipment, and particularly relates to a manufacture method and use method of tracheal intubation equipment of a rat acute myocardial infarction model. A needle core and an inner guide wire of the needle core are respectively a guide needle and a loach guide wire (Terumo super-slippery M-shaped loach guide wire in Japan) used for coronary artery intervention; the soft end of the guide wire penetrates through the tail end of the guide needle and is exposed from the head end of the guide needle by 0.4cm; and the redundant guide wire at the tail end of the guide needle is cut off. An outer-layer hose is prepared from an infusion needle of disposable venous infusion apparatus (Shanghai Youyu Medical EquipmentCo., Ltd., 0.5x20 infusion apparatus), wherein the length of the outer-layer hose is shorter than the length of a catheter needle by 0.3 cm, and the root of the hose is cut obliquely by a movable flap which accounting for 1/
