内窥镜防交叉感染安全保护套的研制

目的：改善目前内窥镜消毒欠佳的状况，研制内窥镜防交叉感染安全保护套。方法：选用无毒、无害、无味、透明、有弹性的医用橡胶，加工成圆管状或圆筒状，其大小与内窥镜前部的镜身相吻合。前后端开口处设置内藏加厚圈。每只以保护套的中线为轴心搓卷成卷桶状，消毒灭菌后装袋备用。结果：保护套结构简洁流畅，能够经内窥镜的末端顺利退卷并套上内窥镜镜身且紧密贴附。结论：内窥镜防交叉感染保护套能够有效地避免内窥镜镜身沾染受检者的血液黏液以及可能存在的病原微生物，降低医源性交叉感染的风险。

Development of Endoscopic Protective Sheath on Anti-cross-infection

Objective To improve the unsatisfactory situation of endoscope disinfection and develop endoscopic anti-crossinfection security protection sheath. methods The protective sheath was processed by using tube and cylinder of medical flexible rubber that was non-toxic, harmless, tasteless and transparent, which size was coincide with the shank of endoscopic fore-end. The openings of fore-end and back-end were designed by immerse extra-strong circle. Every sheath was molded into barrel roll based on the midline axis of twist and bagging standby after disinfection and sterilization. The instruction of sheath was streamlined that could be unwound smoothly from back-end and accreted tightly to endoscopic mirror. Conclusion The sheath can be reduced effectively the risk of crossinfection in endoscope examination. [Chinese Medical Equipment Journal,2009,30（3）：58,61]
