Description

Radiation protection device

The technical field is as follows:

the utility model relates to a radiation protection device who uses in combining together the environment with radiation therapy equipment belongs to the radiation protection technology field, especially relates to a non-heavy burden radiation protection device that is used for ray intervention diagnosis and treatment.

Background art:

interventional radiology, namely interventional diagnosis and treatment, is a minimally invasive diagnosis and treatment method for placing a special catheter into a human body for diagnosis, repair, expansion and dredging by percutaneous puncture under the guidance of image diagnosis equipment (a digital subtraction X-ray machine, a CT (computed tomography) machine, a nuclear magnetic resonance machine, a conventional X-ray machine and the like), and is a new subject integrating medical imaging, clinical diagnosis and treatment.

In the interventional diagnosis and treatment operation process, an operator needs to finish operation under the condition of close to the whole X-ray monitoring, the pathological changes are visually inspected by observing X-ray perspective images instead of operation exposure, and the pathological changes are used as visual field expansion indication of the operator to indicate whether the target position is reached or not, so that the interventional operator is irradiated by rays with larger dose, and the interventional operator becomes a group with the largest irradiated dose in the current medical irradiation.

At present, the radiation protection equipment such as a lead vest, a lead neckerchief, a triangular towel, lead glasses, a lead cap and the like is generally used for carrying out local radiation protection on an operator in clinic. This radiation protection approach has two major problems: firstly, the radiation protection is not comprehensive, and the use of radiation protection equipment such as lead undershirt, lead muffler, triangular towel, lead glasses, lead cap can only carry out radiation protection to operator's health local position, and the operator health does not shelter from the part still to expose under the radiation, and long-term in the past can cause huge injury to operator's health. Secondly, the radiation protection equipment has heavier articles and the burden borne by the operator is heavy. Because of the nature of the radiation-proof material, the operator wears the radiation-proof equipment during long-time work, and the long-time work feels fatigue.

In order to solve the above problems, a radiation protection device is developed, for example, a radiation protection cover is adopted, and the weight of the radiation protection material is borne by a relevant bracket, so that the burden of an operator is reduced. Although the radiation protection mode (patent number: 201611041522.1) can protect human body from radiation, the device is too large, heavy and inflexible, and the device can not be adjusted according to actual needs, so that the visual field of an operator is limited, and the operation is inconvenient.
