内窥镜在医疗领域的应用越来越广泛，很多科室如内镜室、外科、耳鼻喉科等等都在使用软性内窥镜进行检查、手术，因此相应的软性内窥镜的维护和保养也越来越重要。下面内窥镜设备维修人员来讲讲内窥镜设备喷嘴故障的现象以及事项。

The application of endoscopes in the medical field is becoming increasingly widespread, and many departments such as endoscopy, surgery, otolaryngology, etc. are using soft endoscopes for examination and surgery. Therefore, the maintenance and upkeep of corresponding soft endoscopes are becoming increasingly important. Below, the maintenance personnel of the endoscope equipment will talk about the phenomenon of nozzle failure in the endoscope equipment and the solutions.

喷嘴是连接水、气管路的通道，体积很小，且有一转角。喷嘴使用频次高，故障率也比较高。

The nozzle is a channel connecting water and gas pipelines, with a small volume and a corner. The nozzle is used frequently and has a relatively high failure rate.

(1)故障现象。内镜无水气输出、内镜送水或送气不通畅、送水时呈水滴状。

(1) Fault symptoms. Endoscopy has no water vapor output, endoscopic water or air delivery is not smooth, and water delivery is in the form of water droplets.

(2)故障分析。造成喷嘴故障多数是因为内镜清洗之后血块、组织等吸人物干涸后使喷嘴造成喷嘴堵塞。还有一种情况就是不当的外力导致喷嘴严重变形，导致送水送气不畅。

(2) Fault analysis. The majority of nozzle failures are caused by the blockage of the nozzle caused by the drying of blood clots, tissues, and other suction objects after endoscopic cleaning. Another situation is that improper external forces cause severe deformation of the nozzle, resulting in poor water and air delivery.

(3)故障方案。在发现气、水不畅时应反复按压送气送水按钮，若处理的及时通常情况下可冲出里面的异物；如果冲洗不能，可将精细钢丝轻轻插入喷嘴掏出异物，再反复将水注入送气、送水口直通畅；

(3) Fault resolution. When discovering blockage in air and water, the first step is to repeatedly press the air and water supply button. If handled in a timely manner, foreign objects inside can usually be flushed out; If flushing cannot solve the problem, a fine steel wire can be gently inserted into the nozzle to remove foreign objects, and then water can be repeatedly injected into the air supply and water supply ports until they are unobstructed;

对于堵塞较深，送气、送水管道堵塞的可将清洗内镜的酶洗液注入送气、送水管道，浸泡数分钟后，再用注射器反复加压注气、注水直通畅；

For deeply blocked gas and water supply pipelines, the enzyme washing solution used to clean the endoscope can be injected into the gas and water supply pipelines. After soaking for a few minutes, a syringe can be used to repeatedly pressurize and inject gas and water until it is unobstructed;

如果上述方法都不能堵塞问题，说明送气、送水管道堵塞严重，可使用钟表改锥将喷嘴拆卸下来，用钢丝将喷嘴清理干净后安装回去，封胶晾干。

If none of the above methods can solve the blockage problem, it indicates that the air and water supply pipelines are severely blocked. You can use a clock screwdriver to remove the nozzle, clean it with steel wire, and then install it back. Seal the adhesive and let it dry.
