在使用噴淋清洗機清洗手術器械時，關節、咬合處等復雜結構部位容易殘留污染物（如血液、組織等）是清洗質量控制的重點、難點。

　　When using a spray cleaning machine to clean surgical instruments, complex structural parts such as joints and bite points are prone to residual pollutants (such as blood, tissue, etc.), which is the focus and difficulty of cleaning quality control.

　　裝載時須將器械的關節完全打開，咬合部分打開，可拆卸的部分拆卸后裝載清洗，同時、器械的擺放要避免遮擋和重疊，確保所有部位能夠充分暴露在噴淋水流下。

　　When loading, the joints of the equipment must be fully opened, the bite part must be opened, and the detachable parts must be disassembled before loading and cleaning. At the same time, the placement of the equipment should avoid obstruction and overlap, ensuring that all parts can be fully exposed to the spray water flow.

　　但噴淋清洗真的能徹底清洗干凈嗎？

　　But can spray cleaning really thoroughly clean?

　　我們做個實驗觀察一下：

　　Let's conduct an experiment to observe:

　　將器械關節打開涂抹模擬污染物后固定在籃筐底部，放入清洗消毒器內，先進行噴淋清洗、再進行超聲波清洗，用視頻記錄清洗全過程。

　　Open the joint of the instrument and apply simulated pollutants, then fix it at the bottom of the basket and place it in a cleaning and disinfection device. First, perform spray cleaning, followed by ultrasonic cleaning, and record the entire cleaning process with video.

　　經過噴淋清洗后，肉眼可見器械表面的模擬污染物基本去除，但關節處仍有模擬污染物殘留。

　　After spray cleaning, the simulated pollutants on the surface of the instrument visible to the naked eye were basically removed, but there were still residual simulated pollutants at the joints.

　　再進行超聲波清洗，清洗過程中可觀察到模擬污染物逐漸分解、剝離。

　　Further ultrasonic cleaning can be performed, during which simulated pollutants can be observed gradually decomposing and peeling off.

　　結論：

　　Conclusion:

　　噴淋清洗機能夠快速高效的去除器械表面的污漬，但細小縫隙中的污漬去除能力不足，超聲波清洗能夠彌補這一問題。故建議：常規器械定期開展超聲波處理，以去除關節處、咬合齒口部等頑固的污漬。

　　Spray cleaning machine can quickly and efficiently remove stains on the surface of instruments, but its ability to remove stains in small gaps is insufficient. Ultrasonic cleaning can make up for this problem. Therefore, it is recommended to regularly perform ultrasonic treatment on conventional instruments to remove stubborn stains such as joints and bite teeth.
