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 / 3 of the circumference of the hose. After anaesthesia, a rat is fixed and is subjected to
skin preparation, a rat tongue is clamped out with a small tweezer, the
tongue tip ispulled by a left hand, and a
tracheal intubation pipe is hold by a right hand. A hard
catheter needle at the head end of the tracheal
intubation needle core is arranged at the root part of the rat tongue, and a trachea opening of the rat is searched by fine adjustment of the self-made tracheal
intubation pipe under
direct vision. The guide wire at the head end of the tracheal
intubation pipe is sent in instantly when the trachea opening is opened, then the guide wire at the head end is inserted into the trachea opening by about 1cm through rotation, and the
catheter needle is pulled out, wherein if the rat can breathe uniformly and smoothly, intubation is successful.
