新型气管导管的研制及应用

Research and Application of New Tracheal Catheter

目的:研制一种用于各种大、中型手术需要麻醉时进行呼吸管理的新型气管导管。方法:选用一次性使用的无毒透明塑胶类,在塑胶内采用材质为不锈钢、韧性强、制作间距规则的螺旋形细钢丝进行加固;管径的粗细根据气管导管的不同型号而变化;在气管导管进入患者气管内部分别有可膨胀性充气囊、出药液口等;在气管导管连接麻醉机端设有可调节气管导管前端上、下方向的伸拉线指圈、注入药液接注射器口、气囊注气连接注射器口等。结果:气管导管防打折性好,上、下方向可进行调节,前端可进行注药,密封性强。结论:该气管导管更加完善了临床操作的不足,为困难气道的处理增加了新的手段,增加了气管内给药途径,非常符合临床实际需要。

Objective To develop a new kind of tracheal catheter for large or medium-sized surgical anesthesia as a medical equipment of respiratory management, and to rescue the patients with anhelation of respiratory arrest, which is essential to first-aid treatment and will be widely used clinically. Methods The disposable non-toxic transparent plastic was adopted, which was reinforced by the spiral stainless steel wire with regular separations. The diameter of the tracheal catheter varied with the different models. The tracheal catheter was composed of the items put into the trachea when applied for anesthesia such as the inflatable bladder and liquid mouth, the ones connected with the anesthesia machine such as the ring lines regulating direction of the front end of the catheter, and the syringe adapters for the liquid and gas. ~ The flexible, air-proof tracheal catheter, with its direction adjustable, injected the medicine through its front end. Conclusion The tracheal catheter can be used for intratraeheal medication, and will be popularized clinically.
