[Objective] Through the design and manufacture of protective devices, interventional X-ray machine to take protective measures to achieve the purpose of effective interventional physicians. [Methods] According to the situation of interventional X-ray machine, the X-ray radiation area of the operation site was analyzed and an effective protective device was designed and manufactured. The radiation dose before and after interventional operation was tested and the shielding efficiency was observed. [Results] The designed and manufactured “X” shaped horizontal and vertical shielding device reduced the dose of main part of the interventional surgery body from 0 0, 300 μGy / h to 0.3, 2 μGy / h and the shielding efficiency was 76.9 % ~ 99.9%. [Conclusion] The device is reasonable in design, strong in applicability, good in protective effect and suitable for popularization and use
