What you want to ask is, can I buy second-hand medical equipment? Of course. According to the query of Medical Network, when transferring second-hand medical devices between users of Class II medical devices, they should sign an agreement, hand over product manuals, use and maintenance records and copies of files, and transfer them only after passing the inspection by qualified inspection institutions. The second category of medical devices refers to medical devices whose safety and effectiveness should be controlled, including X-ray filming machines, B-ultrasound, microscopes and biochemical instruments.
