程序的抵抗力
The contra-angle handpiece could be capable of being subjected to 250 cycles
of sterilizing procedure.手机可以进行 250 次消毒程序循环。
Preparation at
the Point of Use
使用点的准备
The post-operative process must be carried out immediately, no later than 30
minutes after the completion of the operation. The steps are as follows:
Remove the shanks/files and disconnect the contra-angle handpiece from
Motor handpiece. Remove gross soiling of the instrument with cold water
(<40°C) immediately after use. Don't use hot water (>40°C) as this can cause
the fixation of residuals which may influence the result of the reprocessing
process.术后过程必须立即进行，不迟于手术完成后 30 分钟。 步骤如下：
拆下刀柄/锉刀并断开弯手机与马达手机的连接。 使用后立即用冷水
(<40°C) 去除仪器上的脏污。 不要使用热水 (>40°C)，因为这会导致残留物
固定，从而影响再处理过程的结果。
Transportati
on 运
输
The contra-angle handpiece should be safety stored and transported to the
point of reprocessing to avoid any damage and environment pollution.反角手机
应安全储存，运输至再处理点，以免造成损坏和环境污染。

Preparation for
reprocessing
The products must be reprocessed in a disassembled state.产品必须在拆卸状
态下进行再加工。
Pre-cleaning 预清
洁
Tools: tray, soft brush, clean and dry soft cloth
Perform manual pre-cleaning until the handpiece is visually clean. Rinse the
chuck of bur with running water for at least 10 seconds. Clean the surface with
a soft bristle brush.
Note: The water temperature should not exceed 40℃during the washing
stage, otherwise the protein will solidify and be difficult to remove.
工具：托盘、软刷、清洁干燥的软布
执行手动预清洁，直到机头目测清洁。 用流水冲洗车针夹头至少 10 秒钟。
用软毛刷清洁表面。
注意：洗涤阶段水温不宜超过 40℃，否则蛋白质会凝固，难以去除。
Cleaning
Regarding cleaning/disinfection, rinsing and drying, it is to distinguish
between manual and automated reprocessing methods. Preference is
to be given to automated reprocessing methods, especially due to the
better standardizing potential and industrial safety.关于清洗/消毒、漂洗和干
燥，是区分手动和自动再处理方法。 优先考虑自动再处理方法，特别是
由于
更好地标准化潜在和工业安全。
Automatic cleaning 自动清洗
The washer-disinfector should meet the requirements of the ISO 15883. Place
the contra-angle handpiece in the washer-disinfector carefully.
Ensure that contra-angle handpieces can not move freely in the
washer-disinfector.
The contra-angle handpiece are not permitted to contact with each other. Start
the program:
•
4min pre-washing with cold water(<40℃);
•
Emptying
•
5 min washing with a mild alkaline cleaner at 55℃；
