Figure 1 Esophageal Ultrasound Probe and Main Structure

Power Connector:The core of the pin area is the circuit board,Cannot Enter water，easy to corrode and cause short circuits. How to waterproof during cleaning?

Cable:Contains a built-in metal wire with an outer soft rubber protective layer; excessive pulling during handling can cause cable breakage, affecting image quality;The soft rubber protective layer is easily damaged, duringhandling, what should be paid attention to?

Operating Handle and Knob:The knob is connected to the built-in metal wire and has gaps. If disinfectant or other liquids Enter the control device,it will corrode the gears,Cannot be fully immersed for cleaning and disinfection?

Insertion Part and Tip：During treatment, it contacts the patient's mouth, esophagus, and gastric cavity. Contaminants include saliva, esophageal secretions, and gastric juice. The gastric juice has a pH of 2-3, which is strongly acidic and easilycorrodes the instrument，how to achieve effective pre-processing?

Manufacturer's Instructions："Avoid using coupling agents containing ethanol, propanol, mineral oil, grease, or any type of detergent or softener, as they may damage the probe."
