Sterilization in Medical Packaging

Cold plasma sterilization device for precisely sterilizing instruments and consumables by optimizing the plasma exposure parameters based on the surface area and volume of the object being sterilized. A controller determines the plasma release time, object rotation speed, and other parameters based on the object's exposed surface area and volume to provide targeted and effective sterilization. This addresses issues with overall disinfection not fully reaching contaminated areas. The device can be used for items like test tubes where fixed-point sterilization can be performed by moving the plasma nozzle to the specific location.
