Technical Field

[0001] The present invention relates to the technical field of radiation protection equipment, and in particular to radiation protection equipment for an examinee in a CT examination. Background Art

[0002] CT examination is an important medical detection method that can provide reliable and effective assistance to doctors in diagnosing patients. However, CT rays are also a burden on the patient's body, and necessary protection is required for unexamined parts.

[0003] At present, the protective equipment commonly used in hospitals for chest CT examinations is lead caps, lead neckbands, and lead aprons. During chest CT examinations, the gonadal organs in the abdomen and pelvis can be covered and shielded by the lead aprons, but the radiation-sensitive organ in the neck, the "thyroid gland", is almost ineffective if it is only shielded by the lead neckband in the picture. Because the tube rotates during CT scanning, the direction of the radiation is 360°, and it is ineffective to only shield the surface of the thyroid gland, and it will also cause secondary damage to the thyroid gland by scattered radiation.

[0004] Therefore, there is an urgent need for a radiation protection device for subjects in CT examinations to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a radiation protection device for a subject in a CT examination, which has a simple structure, is easy to use, and can effectively protect the patient's neck from radiation.

[0006] The embodiment of the present invention is achieved as follows:

[0007] An embodiment of the present application provides a radiation protection device for a subject in a CT examination, which includes a main protective part, the main protective part includes a cushioning layer and a protective layer, and the protective layer is arranged on the outside of the cushioning layer; the protective layer includes a neck and an extension part, the neck and the extension part are connected, and the inner side surfaces of the two are inclined from the inside to the outside.

[0008] In some embodiments of the present invention, a plurality of the protective layers are disposed around the liner layer.

[0009] In some embodiments of the present invention, the two adjacent protective layers are hingedly connected.

[0010] In some embodiments of the present invention, hook grooves and hooks are respectively provided on both sides of the protective layer, and a supplementary layer is provided between two adjacent protective layers, and the supplementary layer is provided in an arc shape.

[0011] In some embodiments of the present invention, a reflector is disposed on the inner side of the protective layer, and the reflector is provided with an inclined surface and a vertical surface, and the inclination angle of the inclined surface is smaller than the inclination angle of the protective layer.

[0012] In some embodiments of the present invention, the cushion layer and the protective layer are detachably connected.

[0013] In some embodiments of the present invention, a protective layer is disposed on the outer side of the protective layer.

[0014] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0015] The existing CT inspection protection equipment has almost no actual effect on shielding the neck, and may also cause secondary damage to the thyroid gland by scattered rays. The present invention provides a CT inspection subject radiation protection equipment, which includes a main protection part, the main protection part includes a cushion layer and a protective layer, and the protective layer is arranged on the outside of the cushion layer; the protective layer includes a neck and an extension part, the neck and the extension part are connected, and the inner side surfaces of the two are arranged to be inclined from the inside to the outside.

[0016] The present invention provides a protective layer with a neck and an extension in sections, so that the protective layer can not only protect the radiation directly directed to the patient's neck, but also, when facing scattered radiation, the radiation directed to the thyroid gland from the side will also be scattered outwards under the influence of the outwardly inclined neck and the inner side of the extension, thereby avoiding radiation damage to the neck and effectively protecting the neck.
