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.

影響醫(yī)用超聲波清洗效果的參數有很多，如頻率、功率、清洗介質、溫度等，而其中影響大的因素就是超聲波頻率。

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.

超聲波清洗頻率越低，空化效應產生的氣泡數量少、直徑大，當空化氣泡破裂時釋放的沖擊能量高，對器械表面的沖擊力也越大，適用于清洗表面附著大顆粒污垢或污垢與表面結合強度高的器械。隨著超聲波清洗頻率的增大，空化氣泡的數量呈線形增加，其直徑也隨之減小，從而產生更多更密集的沖擊波使其能夠進入到更小的細縫中，有利于細小狹縫的精密清洗。

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.

醫(yī)用超聲波清洗機怎么選擇頻率？醫(yī)用超聲波清洗機常用的頻率有40KHz、80KHz、100KHz三種，目前市面上的醫(yī)用超聲波清洗機大多數都是以一機單頻為主，而潔盟超聲波清洗機可將各種頻率分別組合，做到一機雙頻，甚至達到一機三頻的清洗方式，可以實現粗洗（普通器械）、清洗（腔鏡器械）、精洗（精密器械）三種方式的清洗，使得附著在醫(yī)用器械上不同性質的污垢得到全方位的清洗，達到更潔凈的清洗效果。

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.
