Aging problem of outsourcing polyethylene hose

这主要由几方面因素所决定，如环境、温度、湿度、操作使用等等。上述几项一般容易做到，容易忽略的是液的浓度、温度、浸泡时间对其影响很大。因而在清洗，过程中对外包聚乙烯胶管的护理保养显得很重要，要按清洗、规程办，同时参照OLYM PUS公司清洗、提议，注意事项。

This is mainly determined by several factors, such as environment, temperature, humidity, operational use, and so on. The above items are generally easy to achieve, but it is easy to overlook that the concentration, temperature, and soaking time of the disinfectant have a significant impact on it. Therefore, in the process of cleaning and disinfection, it is important to take care of and maintain the outer polyethylene hose. It is necessary to follow the cleaning and disinfection procedures, and refer to the cleaning and disinfection suggestions and precautions of OLYM PUS company.

打气、打水通道阻塞。

Blocked ventilation and drainage channels.

电子胃镜出气、出水通道设计成“Y”型，出气、出水管道经过胃镜操作部“送气、送水”按钮共用一个通道由喷嘴喷出，喷嘴呈扁平状，口径才几毫米，极易被黏液、胃黏膜中的蛋白质凝固物所阻塞，一旦梗阻极难疏通，虽然可用酶类剂浸泡，及时分解凝固的蛋白质，再用OLYMPUS公司配置的全管道灌流器冲洗，疏通一般的阻塞问题，但是严重阻塞，只能由公司方维修才能，切不可自行用针类器具贸然行事，搞不好会造成漏气、漏水，轻则引起内部器件锈蚀，重则摄像CCD受到损害，导致电子胃镜不能正常工作。

The air outlet and water outlet channels of the electronic gastroscope are designed as a "Y" shape. The air outlet and water outlet pipes share a common channel through the "air and water supply" button of the gastroscope operation department, and are sprayed out by the nozzle. The nozzle is flat and has a diameter of only a few millimeters, which is easily blocked by mucus and protein clots in the gastric mucosa. Once obstructed, it is extremely difficult to clear, although enzyme disinfectants can be used to soak and timely decompose the clotted protein, Rinse with the full pipeline perfusion device configured by OLYMPUS company to clear the general blockage problem. However, severe blockage can only be solved by the company's maintenance. Do not act recklessly with needle instruments, as it may cause air and water leakage. At times, it may cause internal device corrosion, and at worst, damage to the camera CCD, resulting in the electronic gastroscope not working properly.

镜身过软，操作部、弯曲部失灵。

The mirror body is too soft, and the operating and bending parts are malfunctioning.

上述现象可能与环境温度、湿度等使用情况有一定关系，有时冷光源散热不畅，操作时间过长也是影响的因素之一。操作部与弯曲部失灵，可能是某一方位(或多方位)的角度钢丝脱落或者拉长，这大概与操作手法有一定的关联，应尽量避免角度调节时动作过猛、用力过大、强行转动，以致鼓轮挤压摩擦角度钢丝绳，造成拉长及断丝或者端头脱出等故障。

The above phenomenon may be related to environmental temperature, humidity, and other usage conditions. Sometimes, poor heat dissipation of cold light sources and prolonged operation time are also factors that affect it. The failure of the operating and bending parts may be due to the detachment or elongation of the angle steel wire in a certain direction (or multiple directions), which is probably related to the operating method. It is necessary to try to avoid excessive action, excessive force, or forced rotation during angle adjustment, which may cause the drum to compress the friction angle steel wire rope, causing elongation, wire breakage, or end detachment and other faults.

镜面模糊。导光束断裂。

Mirror blurry. The guide beam is broken.

在冬季使用时，容易发生此类现象，主要是环境温度与人体温度短时反差过大而致，使用前应用温湿纱布反复擦洗镜身或用温水浸泡(是有空调环境)。另外擦镜面时应用擦镜布(麂皮)，不可用其他(如纱布)代替。导光束断裂的原因除了镜身过软，昼夜温差过大；其次是软管部分折绕直径太小(小于12cm)；再是电子胃镜导光接头从冷光源拔下时，触摸或触及温差大的物体所致。电子胃镜不用时放人专用恒温柜内或二十四小时不间断开启空调环境中。

When used in winter, this phenomenon is prone to occur, mainly due to the large short-term difference between the ambient temperature and the human body temperature. Before use, the mirror body should be repeatedly wiped with warm and wet gauze or soaked in warm water (preferably in an air-conditioned environment). In addition, professional lens wiping cloth (suede) should be used when wiping the mirror surface, and other cloth (such as gauze) cannot be used as a substitute. The reason for the breakage of the guide beam is not only due to the mirror body being too soft, but also due to the large temperature difference between day and night; Secondly, the bending diameter of the hose is too small (less than 12cm); It is also caused by touching or touching objects with large temperature differences when the electronic gastroscope light guide connector is unplugged from the cold light source. When not in use, it is best to place the electronic gastroscope in a dedicated constant temperature disinfection cabinet or in an air conditioning environment that is continuously turned on 24 hours a day.

随着经济的发展，电子胃镜的出现为医学诊断的提高提供了较大的帮助。电子胃镜在使用过程中无法避免的会出现各种故障，因此维修人员必须掌握维修要点，以确保电子胃镜系统的正常运行。 但需注意的是当电子胃镜出现了故障，大家判断自己无法修复时，尽量不要随意拆解设备，可以找的维修公司进行处理！

With the development of the economy, the emergence of electronic gastroscopy has provided significant assistance for the improvement of medical diagnosis. Various malfunctions are inevitable during the use of electronic gastroscopy, so maintenance personnel must master the key points of maintenance to ensure the normal operation of the electronic gastroscopy system. But it should be noted that when there is a malfunction in the electronic gastroscope and everyone judges that they cannot repair it, try not to disassemble the equipment randomly and find a professional maintenance company to handle it!
