一种多管可视喉罩
本使用新型属于医疗器械
,具体涉及一种多管可视喉罩。
技术介绍
80年代中期,喉罩作为一种用于维护患者呼吸换气的医疗器械,在临床麻醉、急救或者复苏中得到了广泛应用。随着材料和技术的进步,多种不同类型的喉罩被研发改进,但现有技术的喉罩还有很多问题存在,传统的单管喉罩与呼吸道密封不完全,易移位,无法有效隔离呼吸道和消化道,可引起胃胀气,严重时并发返流或误吸,限制了其在临床麻醉中的应用。临床研究表明,食道引流型喉罩具有操作简单、置管成功率高、防误吸的优点。但是随着医疗临床要求提高,咽喉部实时监测与插管置换功能的需求日渐强烈,并且传统喉罩在耳鼻喉科临床手术中无背囊引流功能,大大影响喉罩的临床应用效果,限制各科室间交叉的应用。
技术实现思路
为解决上述问题,本技术提供一种多管可视喉罩,该喉罩临床应用有效性和安全性大大提高,易于在临床麻醉中推广应用。本技术的目的是以下述方式实现的:一种多管可视喉罩,包括软罩和与软罩连接的主体管,软罩背部设有痰液收集腔和胃管腔,痰液收集腔的吸痰孔对称设置在软罩背部两侧,每侧至少有3个吸痰孔,痰液收集腔通过两侧收集腔合并的吸痰管与 ...
