Usage and Maintenance Notes:
1.Only use sterile and sharp medical puncture needles for operation. Avoid damaging the model materials with blunt needles or broken needle tips.
2.After each use, wipe the surface with clean water or mild medical cleaner, and store it in a cool and dry place sealed. Avoid direct sunlight or high-temperature environments.
3.Do not use alcohol, grease or corrosive liquids to clean the model to prevent material aging or affecting the ultrasonic performance.
4.When the model shows obvious damage, blurred ultrasonic images or distorted puncture sensation, replace it in time to avoid affecting the training effect.
