上消化道出血病人进行内镜检查时,病变处常被覆血液,血凝块及咖啡渣样物,而用激光、电凝、注射硬化剂等止血治疗时,准确地看清出血部位十分重要。对于这种情况,我们使用改进的水冲刷器。它包括脚踏控制的水泵。这个水泵使用三通管和14F的斜面针与内镜活检孔连接。强大的水流(可达500ml/分)通过内镜的活检抽吸孔来冲洗病变处的血液和血凝块。 Patients with upper gastrointestinal bleeding endoscopy, the lesions are often covered with blood, blood clots and coffee grounds like samples, and laser, electrocoagulation, sclerotherapy and other hemostatic treatment to accurately see the bleeding site is very important. For this situation, we use a modified water scrubber. It includes a foot control pump. This pump uses a tee and a 14F bevel needle to connect with the endoscopic biopsy port. Powerful flow (up to 500ml / min) Flush blood and blood clots at the lesion through the biopsy suction port of the endoscope.
