Expanded Information
Passive medical devices do not produce harmful side effects even after being used in the human body and are able to perform during the design life of the passive medical device. This includes three aspects: first, the safety of the patient, from time to time can have a near-term or long-term safety; second, the safety of medical personnel and operators; in addition to the safety of the surrounding environment.
Active contact with the human body devices: energy therapy devices, diagnostic and monitoring devices, liquid delivery devices, ionizing radiation devices, implantable devices, other active contact with the human body devices.
Active non-contact human devices: clinical testing instruments and equipment, independent software, medical device sterilization equipment, other active non-contact human devices.
