內窺鏡在醫療領域的應用越來越廣泛，很多科室如內鏡室、外科、耳鼻喉科等等都在使用軟性內窺鏡進行檢查、手術，因此相應的軟性內窺鏡的維護和保養也越來越重要。下面
內窺鏡設備維修人員來講講內窺鏡設備噴嘴故障的現象以及事項。
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.
噴嘴是連接水、氣管路的通道，體積很小，且有一轉角。噴嘴使用頻次高，故障率也比較高。
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)故障現象。內鏡無水氣輸出、內鏡送水或送氣不通暢、送水時呈水滴狀。
(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。造成噴嘴故障多數是因為內鏡清洗之后血塊、組織等吸人物干涸后使噴嘴造成噴嘴堵塞。還有一種情況就是不當的外力導致噴嘴嚴重變形，導致送水送氣不暢。
(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。在發現氣、水不暢時應反復按壓送氣送水按鈕，若處理的及時通常情況下可沖出里面的異物；如果沖洗不能，可將精細鋼絲輕輕插入噴嘴掏出異物，再反復將水注入送氣、送水口直通暢；
(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;
對于堵塞較深，送氣、送水管道堵塞的可將清洗內鏡的酶洗液注入送氣、送水管道，浸泡數分鐘后，再用注射器反復加壓注氣、注水直通暢；
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問題，說明送氣、送水管道堵塞嚴重，可使用鐘表改錐將噴嘴拆卸下來，用鋼絲將噴嘴清理干凈后安裝回去，封膠晾干。
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.
That's all for the explanation of the phenomenon of nozzle failure in endoscopic equipment and the related matters to be solved. We hope to provide you with good help. For more information, please come to our website http://www.yojeim.com consulting service
