Medical ultrasonic cleaning machine is a kind of medical instrument cleaning equipment widely used in gastroscope room, laryngoscope room, operating room and disinfection supply center. In order to ensure that the cleaned instruments can meet the cleanliness requirements of high standards, when purchasing medical ultrasonic cleaning machines, it is necessary to select appropriate parameters of ultrasonic cleaning machines according to the characteristics of instruments and the nature of attached dirt.

影响医用超声波清洗效果的参数有很多，如频率、功率、清洗介质、温度等，而其中影响大的因素是超声波频率。

There are many parameters that affect the effect of medical ultrasonic cleaning, such as frequency, power, cleaning medium, temperature and so on, among which the most influential factor is ultrasonic frequency.

超声波清洗频率越低，空化效应产生的气泡数量少、直径大，当空化气泡破裂时释放的冲击能量高，对器械表面的冲击力也越大，适用于清洗表面附着大颗粒污垢或污垢与表面结合强度高的器械。随着超声波清洗频率的增大，空化气泡的数量呈线形增加，其直径也随之减小，从而产生更多更密集的冲击波使其能够进入到更小的细缝中，有利于细小狭缝的精密清洗。

The lower the ultrasonic cleaning frequency is, the smaller the number of bubbles produced by cavitation effect and the larger the diameter is. When the cavitation bubble breaks, the higher the impact energy released and the greater the impact force on the surface of the instrument. It is suitable for cleaning instruments with large particle dirt attached to the surface or high bonding strength between dirt and the surface. With the increase of ultrasonic cleaning frequency, the number of cavitation bubbles increases linearly and their diameter decreases, resulting in more and more dense shock waves, which can enter into smaller slits, which is conducive to the precise cleaning of small slits.

医用超声波清洗机怎么选择频率？医用超声波清洗机常用的频率有40KHz、80KHz、100KHz三种，目前市面上的医用超声波清洗机大多数都是以一机单频为主，而洁盟超声波清洗机可将各种频率分别组合，做到一机双频，甚达到一机三频的清洗方式，可以实现粗洗（普通器械）、清洗（腔镜器械）、精洗（精密器械）三种方式的清洗，使得附着在医用器械上不同性质的污垢得到的清洗，达到更洁净的清洗效果。

How to choose the frequency of medical ultrasonic cleaning machine? There are three common frequencies of medical ultrasonic cleaning machines: 40KHz, 80kHz and 100kHz. At present, most of the medical ultrasonic cleaning machines on the market are based on one machine with single frequency, while jiemeng ultrasonic cleaning machine can combine various frequencies to achieve the cleaning mode of one machine with dual frequency or even one machine with three frequencies. It can realize the cleaning of three modes: rough cleaning (ordinary instruments), cleaning (endoscopic instruments) and fine cleaning (precision instruments), The dirt with different properties attached to medical instruments can be cleaned in an all-round way to achieve a cleaner cleaning effect.
