Technical Field
The invention relates to the technical field of medical instruments, in particular to an ionizing radiation isolation cabin for cardiac intervention operation and an isolation method.
Background
In the heart intervention operation, after a tube is punctured and placed from the right radial artery or the right femoral artery of a patient, a radiography or treatment catheter is used to extend to the heart along the blood vessel so as to implant a stent or inject thrombolytic drugs, in the operation process, a C-arm machine is continuously used to emit X rays to the heart part of the patient so as to perform searchlighting guidance, and a contrast agent is used to determine the lesion part and determine the operation effect.
In the cardiac intervention operation, the patient, the operation table 1 and the C-arm machine 100 are in the position relationship as shown in fig. 8, the patient lies on the back on the operation table 1, the ray emitting device 101 at the upper end of the C-arm machine 100 faces the chest of the patient, and the ray receiving device 102 at the lower end of the C-arm machine 100 is located at the lower end of the operation table 1. The C-arm machine 100 generates rays through the ray transmitting device 101, receives the rays through the ray receiving device 102, and theoretically, all the radiation generated by the rays is located in the head, neck and chest areas of the patient, but the rays are scattered when penetrating through a human body, a bed plate of an operating bed and other objects, so that a certain radiation dose also exists in other areas in the operating room, medical staff perform an operation in a radiation environment, and the patient receives the operation in the radiation environment.
The continuous radiation can cause serious adverse effects of cancer, teratogenesis, cataract of eyes, immunity reduction, thyroid diseases and the like to medical care personnel and patients.
