Description

Multiple protection machanism of ray of removal CT

Technical Field

The utility model relates to a radiation multiple protection mechanism of a mobile CT, belonging to the technical field of medical equipment.

Background

Mobile CT is an X-ray computed tomography apparatus suitable for human diagnosis. During a CT scan, X-rays may enter the surrounding environment by way of scattering and transmission. If there is no protection measure or improper protection for the X-photons emitted during CT operation, ionizing radiation damage may be caused to doctors, patients and the public.

The conventional CT is generally installed in a shielding room, and an X-ray absorbing material is used in the wall of the shielding room, so that X-rays can be effectively prevented from being transmitted out of a scanning room, and thereby doctors, patients and the public are protected from ionizing radiation. The mobile CT is different from the conventional CT, has the characteristics of small volume, convenient movement, easy operation, small radiation and the like, and can be used in emergency rooms, operating rooms, wards, ambulances and ships, and because the places have no shielding room, doctors, patients and the public cannot be protected against ionizing radiation through the shielding room.

The protective bottom plate is provided with an X-ray outlet.

The inner wall protection layer a, the inner wall protection layer b and the inner wall protection layer c are tungsten alloy silica gel films.

The protective cover and the protective bottom plate are made of tungsten alloy.

The top of the rear shielding curtain is rotationally connected with a rear suspension, and the rear suspension is hung on the rear shell.

The top of the front shielding curtain is rotationally connected with a front suspension, and the front suspension is hung on the front shell.

And tungsten alloy silica gel film shielding layers are arranged on the surfaces of the rear shielding curtain and the front shielding curtain.

The beneficial effects of the utility model are as follows:

1. the mobile CT has a shielding function, and can realize the examination of a patient without carrying out an extra special shielding place during scanning.

2. The mobile CT adopts multiple protection, so that the X-ray can not leak, and radiation pollution can not be generated to operators and surrounding environment.

3. The protective layer is made of tungsten alloy material, and compared with a traditional lead shielding plate, the lead shielding plate has smaller space occupation ratio, and the size of the whole device can be miniaturized.

4. After the tungsten alloy silica gel film is adopted as the shielding layer, the complex curved surface adhesion can be carried out due to the good flexibility, so that the shielding layer is more comprehensively covered and more fully protected.
