超声波清洗机的秘密,超声性能的验证
The secret of ultrasonic cleaning machine and the verification of ultrasonic performance
CSSD的设备，大多数都需要两个方面的检测。一个是设备本身性能的验证（PQ），另一方面是效果的监测。全自动清洗机需要进行性能验证（温度时间测试）和清洗效果检测（如ATP法、蛋白残留测试等）【ISO 15883】，器需要进行性能验证（温度压力测试）和效果监测（如生物监测）【WS 310】，封口机需要进行性能验证和封口效果测试......类似的，超声波清洗机也可以进行着两个方面的检测，这里只针对性能验证做一些介绍。
Most CSSD devices need two aspects of detection. One is the performance verification (PQ) of the equipment itself, and the other is the effect monitoring. Performance verification (temperature and time test) and cleaning effect test (such as ATP method, protein residue test, etc.) [ISO 15883] are required for automatic cleaning and disinfection machines, performance verification (temperature and pressure test) and sterilization effect monitoring (such as biological monitoring) [WS 310] are required for sterilizers, and performance verification and sealing effect test are required for sealing machines... Similarly, ultrasonic cleaning machines can also be tested in two aspects, Here we only introduce performance verification.

由于超声清洗的原理是空化效应，因此它的性能验证主要还是对空化效应的验证，目的是看看清洗槽里面的声场强度是否有盲区。方法很多，这里例举几个作为参考。
Since the principle of ultrasonic cleaning is cavitation effect, its performance verification is mainly to verify the cavitation effect to see whether there is a blind area in the intensity of the sound field in the cleaning tank. There are many methods. Here are some examples for reference.
（1）铝箔腐蚀法
(1) Aluminum foil corrosion method
将20-30&尘耻;尘厚的铝箔固定在一个支架上，垂直放入清洗槽内，不接触底部。开机一段时间后取出，铝箔表面不同地方被腐蚀的程度可以间接反映该深度的超声强度是否均匀。如果要检测水平方向上的超声强度分布，可以将铝箔水平放置。有厂家说明书指出，若出现＞1平方英寸（6.45肠尘2）的空白位置则为冷点。
20-30 μ The m-thick aluminum foil is fixed on a bracket and placed vertically in the cleaning tank without touching the bottom. After being taken out after a period of time, the corrosion degree of different parts of the aluminum foil surface can indirectly reflect whether the ultrasonic intensity at this depth is uniform. If the ultrasonic strength distribution in the horizontal direction is to be detected, the aluminum foil can be placed horizontally. It is pointed out in the manufacturer's manual that if there is a blank position ＞ 1 square inch (6.45cm2), it is a cold spot.
该方法直观、简单，但不能定量测试，误差较大，装载器械的条件下难以实现测试，可能跟碱性清洗剂产生化学反应。有时候还会整块脱落，所以要设置好超声的时间。
This method is intuitive and simple, but it can not be tested quantitatively with large error. It is difficult to test under the condition of loading equipment, and may react with alkaline detergent. Sometimes the whole piece will fall off, so set the ultrasonic time.
（2）玻片洗除法
(2) Slide washing
每周使用HB铅笔涂抹玻片，超声清洗在3min内洗掉则为合格，记录结果（美国IAHCSMM再教育培训手册 2006）。
Use HB pencil to smear the slide every week, and ultrasonic cleaning will be qualified if it is washed away within 3min. Record the results (American IAHCSMM Re education Training Manual 2006).
该方法操作简单，但不能定量测试，误差较大。
This method is simple to operate, but it can not be measured quantitatively, and the error is large.
（3）淀粉碘化钾反应法
(3) Starch potassium iodide reaction method
将淀粉处理后作为感光乳剂，涂抹在一面为玻璃的幻灯片上，放置于含有稀碘溶液的水槽中进行超声。在超声空化的作用下，碘与淀粉反应变蓝，导致幻灯片变色，取出幻灯片冲洗、干燥，通过观察变色的区域，用于推断声场的分布情况。
After starch treatment, it is used as a photosensitive emulsion, smeared on a glass slide, and placed in a water tank containing dilute iodine solution for ultrasound. Under the effect of ultrasonic cavitation, iodine reacts with starch to turn blue, causing discoloration of the slide. Take out the slide and wash and dry it. Observe the discolored area to infer the distribution of the sound field.

该方法可以弥补铝箔腐蚀法中铝箔破损的缺点，但也不能定量测试。
This method can make up for the defect of aluminum foil damage in aluminum foil corrosion method, but it can not be measured quantitatively.
（4）染色法
(4) Dyeing method
在水中配置染料（如亚甲基蓝染料），将铜版纸放在水中超声，在超声空化的作用下，染料会附着在纸片上，取出纸片冲洗晾干，观察纸片背景上的染料图案，用于评价声场的分布情况，如果涂料分布不均匀，说明声场不均匀，存在冷点等情况。
Dyes (such as methylene blue dye) are prepared in water. Coated paper is placed in water for ultrasonic treatment. Under the effect of ultrasonic cavitation, the dye will attach to the paper. The paper is taken out for washing and drying. The dye pattern on the paper background is observed to evaluate the distribution of the sound field. If the coating is uneven, the sound field is uneven, and there is a cold spot.
（5）超声能量瓶测试
(5) Ultrasonic energy bottle test
SonoCheck超声能量瓶可用于验证超声波的空化能力，变色所需的时间与超声波的空化能力成正比（美国IAHCSMM再教育培训手册 2006）。根据水槽的容积，在不同位置进行布点，放置能量瓶，观察变色时间。
SonoCheck ultrasonic energy bottle can be used to verify the cavitation capacity of ultrasound, and the time required for color change is proportional to the cavitation capacity of ultrasound (American IAHCSMM Re education Training Manual 2006). According to the volume of the sink, arrange points at different positions, place the energy bottle, and observe the discoloration time.
该方法直观、简单，但也是定性测量。
This method is intuitive and simple, but it is also qualitative measurement.
（6）超声波能量分析仪
(6) Ultrasonic energy analyzer
直接插入溶液中，可以定量探测超声波能量强度大小以及超声波能量密度分布情况。
The ultrasonic energy intensity and the distribution of ultrasonic energy density can be detected quantitatively by directly inserting it into the solution.
在实际工作中，以上方法都可以作为科室自己的监测手段，利弊皆有。超声波清洗机只是清洗流程中的一个环节，而我们的目标是要保证清洗质量，因此，对于流程的建立和优化以及依从，也是必不可少的。
In practical work, the above methods can be used as the department's own monitoring means, with both advantages and disadvantages. The ultrasonic cleaning machine is only a part of the cleaning process, and our goal is to ensure the cleaning quality. Therefore, the establishment, optimization and compliance of the process are also essential.
