dr used bulb tube is not a violation of the law

No violation. Starting in the 1980s, due to the limitations of hospital funds and approvals and other constraints, unable to introduce new CT equipment, a large number of second-hand CT into China's hospitals at all levels, the repair and maintenance of these devices, lack of information, no source of spare parts, basically relying on the repair of spare parts and dismantling of the old equipment to complete the spare parts, as the main body of diagnostic Class III medical devices - CT equipment is still second-hand to dry as an accessory component of Class II medical devices - balloon and a variety of repair parts, their sources and quality are directly ignored. As the main body of diagnostic Class III medical devices - CT equipment is still second-hand, for the dry as an ancillary part of Class II medical devices - bulb tube and a variety of maintenance parts, its source and quality is directly ignored. This led to a high failure rate and low diagnostic accuracy of CT equipment in many hospitals at that time. In order to change this state of affairs, the Ministry of Health and the State Planning Commission jointly issued the Circular on Issues Related to Strengthening the Management of Large-scale Medical Used Equipment in 1996, which explicitly prohibited the importation and use of any form of second-hand medical equipment. As the maintenance of the use of the balloon, although it is a Class II medical device, did not attract the attention of regulators, so the repair or removal of the old balloon has been widely used by the maintenance company, the demand for these has led to a number of repair and removal of the old balloon as a specialized business of the company, the company's focus on the research and development of the balloon in the country has also played a positive role in the research and development of the balloon. So no violation.
