Place in a special box with a soft sponge or polyurethane foam. All speculum and surgical instruments should be placed neatly and tidy. Do not overlap and overlap. After the cover is closed, the internal scope and instruments will not collide with each other during handling. Since the endoscope's lens tube is very thin, it will be bent and deformed due to crushing, bumping, bending, landing, etc., resulting in lens damage or optical axis shift, resulting in unclear or unusable images, so take it out of the box. Or put into the tube endoscope, should be flat with both hands, gently remove or put in, should not lift a section. When the speculum is moved in a rigid container such as a tray, be careful to place it separately from other instruments. Do not over-bounce to avoid collision with the speculum. A desiccant should be provided in the package to keep the inside of the box dry.
