(5)消毒液使蛋白质凝固阻塞喷嘴和水气管;

(5) The disinfectant coagulates the protein and blocks the nozzle and water pipe;

(6)擦试镜面时方向错误;

(6) The direction is wrong when wiping the mirror;

故障检修

Troubleshooting

当喉镜水气不通时,是先把喷嘴卸下然后用导丝从操作部那边通水气管。OLYMPUS的水管和气管在弯曲部位置上通过一个三通跟会合成一条管。

When the water and air of the laryngoscope are blocked, first remove the nozzle, and then use the guide wire to connect the water pipe from the operation Department. The water pipe and gas pipe of Olympus will be combined into a pipe through a tee at the bending position.

维修步骤:

Maintenance steps:

(1)用一号小一字螺丝刀拧松喷嘴螺丝(40型以上多有一个鞘),螺丝不用松出来;

(1) Use a small slotted screwdriver to loosen the nozzle screw (more than 40 types have a sheath), and the screw does not need to be loosened;

(2)将喷嘴取出;

(2) Take out the nozzle;

(3)用导丝在操作部或先端部通水气管,然后加压按钮送水,冲洗水气管道,直到出现很强的一条水流,且送气时气泡很大,然后将水气管中剩余水排出;

(3) Use the guide wire to open the water pipe at the operation part or the tip, then press the button to send water, and flush the water and gas pipe until there is a strong water flow, and the bubbles are large during air supply, and then discharge the remaining water in the water and gas pipe;

(4)用镊子夹镜头纸舔酒精,清洁管道口,直到无污垢;

(4) Use tweezers to clamp lens paper and lick alcohol, and clean the pipe mouth until there is no dirt;

(5)再次试送水送气,防止有污垢掉管道里;

(5) Try to send water and air again to prevent dirt from falling into the pipe;

(6)再用镊子夹镜头纸舔酒精清洁管道口;

(6) Then use tweezers to clamp lens paper and lick alcohol to clean the pipe mouth;

(7)用镊子夹住喷嘴,用小螺丝刀点小许固定黑胶(KE45B)涂于喷嘴的直管部一圈,小心放进管口内,用镊子背面把喷嘴出口压低至管口边,用手摸喷嘴口感觉不刮手,且喷嘴出口要正对IG盖玻璃,然后拧紧喷嘴固定螺丝,在喷嘴边缘和螺丝孔处补胶;

(7) Clamp the nozzle with tweezers, use a small screwdriver to point a small amount of fixed black glue (ke45b) and apply it to the straight pipe of the nozzle for a circle, carefully put it into the nozzle, use the back of the tweezers to press the nozzle outlet down to the edge of the nozzle, touch the nozzle mouth with your hand to feel that you don't scratch your hands, and the nozzle outlet should be facing the Ig cover glass, then tighten the nozzle fixing screws, and fill the glue at the edge of the nozzle and the screw hole;

(8)试送水、送气,要求水流是一条直线冲洒镜面,且水流覆盖镜面90%,送气时气泡要很大,如没达到要求,重复以上步骤;

(8) Try to send water and air. It is required that the water flow should be a straight line to sprinkle the mirror, and the water flow covers 90% of the mirror. The bubbles should be large when sending air. If the requirements are not met, repeat the above steps;

(9)再次补胶,在白炽灯下烘15分钟,再次检查送水送气效果。

(9) Replenish the glue again, bake it under the incandescent lamp for 15 minutes, and check the effect of water and air supply again.
