一种多功能喉罩的研制和应用

目的：研制一种多功能喉罩，在临床可用于气管、支气管异物取出术，肺灌洗手术，肺部止血术，肺部活检术等。方法：在对传统喉罩加以改良的基础上，增加三通结构，三通的一个端口连接喉罩体，另一个端口覆盖密封帽，可由此通入光纤维支气管喉镜或窥镜，另外一端口为15mm标准接口，可连接麻醉机或呼吸机。光纤镜或其他带取物钳的窥镜由密封帽端口进入，经过喉罩体，再经过声门进入气管及（或）支气管实施肺内疾病手术．结果：通过临床应用试验．采用该多功能喉罩进行的全部肺内疾病手术均顺利完成，置镜顺利成功，满意度100％，通气效果优良；术后恢复良好，无明显并发症。结论：多功能喉罩用于肺内疾病诊疗具有安全、可靠、效果好、并发症少等优点，大大拓展了传统喉罩的用途．提高了麻醉和手术的安全性，

Development and Application of Multifunctional Laryngeal Mask

Objoctive To design a muhifunctional laryngeal mask development and can be used in clinical tracheobronchial foreign body removal, surgical lung lavage, lung surgery to stop bleeding and lung biopsy. Methods Three-way Laryngeal Mask is improved base on the traditional laryngeal mask, it adds a three-way channel（adapter）, one end（port） of the three-way channel connected with the laryngeal mask, another end covered the seal cap from which can insert the fiberoptic bronchoscope or endoscope, one another end is a 15mm standard interface for connecting with the respiratory machine or anesthetic machine. The fiberopticscope or other kinds of endoscope will be inserted from the end of seal cap through the laryngeal mask body, the glottis enters trachea to bronchus. The standard end can be connected with the respiratory machine, in the process of operation can adjust the ventilation by manual control or machine-controlled. Results Through the clinical application testing, the use of the multifunctional laryngeal mask for all lung diseases surgery is successful completely, the degree of satisfaction is 100% and the effect of ventilation is excellent. Conclusion The muhifunctional laryngeal mask can be widely used in the clinical various lung disease operation with safe, reliable, effective and advantages of fewer complications, which significantly expand the traditional use of laryngeal mask and considerably increase the security of anesthesia and operation.
