Description
Technical Field
The utility model relates to a balloon inflation syringe for intubation of an air tube.
Background
The tracheal intubation is a method of placing a specific tracheal catheter into the trachea or bronchus through the oral cavity or the nasal cavity and the glottis, and provides optimal conditions for the ventilation, oxygen supply, respiratory tract suction and the like. After the trachea cannula is operated, the patient needs to gas the air bag in the trachea cannula, so that the ventilation effect of the trachea cannula is ensured. The pressure range of the tracheal intubation balloon is generally 25-30mmHg, and the pressure is too high, so that the partial tracheal mucosa is possibly pressed, and the ischemic necrosis of the mucosa is caused, so that the trachea is deformed, and the breathing is influenced. The air bag is inflated by adopting a small amount of air injection method in clinic, the air injection amount is about 2-5mL, the air injection amount is usually about 2-5mL, the air can be just closed, and the air injection amount is preferably 0.3-0.5mL after no leakage sound is detected, the air is discharged every 4-6 hours, and the air injection is carried out again after about 15 minutes of suspension. However, in this way, on the one hand, the body structure of each person is different, the intubation effect is different, no management is performed, and VAP risks are easily generated. Although some air bag pressure monitoring devices are arranged for monitoring the air bag pressure in real time, the air bag pressure is very small, the air bag pressure actually reaches the air bag pressure after passing through a pipeline, and the pressure deviation read by equipment is very large, so that the phenomenon of over-charging can occur more or less. Once the over-inflation phenomenon occurs, the air sac can indirectly increase the compression of the air sac on the human air pipe, and the air pipe is easy to damage. In addition, the trachea cannula is directly communicated with the pressurizing device, and if the air bag leaks air, the pressurizing device is easily polluted.
In the prior art, the inflation of the manual common injector has no data basis, the pressure is easy to be caused to be out of the clinical 25-30 cmH20 range, and the risk of VAP or airway damage is possibly caused; on one hand, the hospital cost is increased during the measurement of the equipment, and in addition, the gas with small gas quantity is easy to generate over-charge, so that the airway is damaged; the equipment needs training and the like, is complex to operate, and the manual operation is serious to the injury of human airways.

In the present embodiment, the inner wall of the piston cylinder 21 is provided with a positioning boss 21b; one end of the piston spring 23 is fixed to the positioning boss 21b, ensuring that the rear end of the piston spring 23 is not displaced.
The piston cylinder 21 is also provided with a pressure scale 21a which is positioned at a corresponding position at the rear end of the piston post 22. The rear end of the piston column 22 has an air pressure pointer 22a; the current pressure value may be indicated by the position of the pressure scale 21a corresponding to the air pressure guide 22 a.
The front end of the piston cylinder 21 is fixedly connected with the piston rubber plug 24, and the rear end of the piston cylinder 21 is sealed, namely, is not opened or is provided with an end cover for sealing.
The external dimension of the piston rubber plug 24 is matched with the dimension of the inner wall of the syringe needle cylinder 1, so that the two are airtight.
The piston rubber plug 24 is provided with vent holes 24a uniformly distributed on the circumference at the front end of the piston cylinder 21, so as to ensure the balance of air pressure to the pressure of the piston column 22.
The syringe needle tube 11 is connected with the inflation tube 4 of the balloon of the trachea cannula through the connecting tube 3. Preferably, the inflation tube 3 is connected with the inflation tube 4 of the balloon of the tracheal cannula through a luer fitting 5.
