In China, a medical device operator training program is required to obtain a medical large-size license, which generally lasts from half a month to about a month, depending on the training organization. After completing the training, you will need to take an exam, which includes a theoretical exam and a practical exam. The theoretical examination covers medical device-related knowledge and operational practices, etc., the practical examination requires a practical demonstration. After passing the exam, you can get a medical large-scale license.
It should be noted that different regions and countries may have different examination requirements and standards, so the exact time of the examination may vary. It is advisable to consult the relevant department or organization for accurate information.
