Furthermore, the two ends of the scanning frame, which are positioned in the scanning hole, are respectively provided with a radiation shield front shield and a radiation shield rear shield, and the radiation shield front shield and the radiation shield rear shield are connected with the outer surface of the radiation shield shell.

Furthermore, radiation-proof materials are filled between the radiation shielding shell and the scanning frame.

Further, the scanning device comprises a rotating shaft, the support is connected with the scanning frame through the rotating shaft, an electric push rod used for swinging the scanning frame is arranged on the support, the telescopic end of the electric push rod is fixedly connected with the scanning frame, and the power supply supplies power to the electric push rod.

The utility model has the advantages that:

1. the CT machine only scans the head, the volume and the weight of a scanning frame can be greatly reduced, the design of miniaturization and light weight is facilitated, the transportation or the installation on an emergency ambulance are facilitated, and simultaneously, the consumed power can be synchronously reduced, so that a small-capacity lithium battery or a small generator can supply power to the CT machine;

2. by arranging the radiation shielding shell and filling the radiation-proof material, all X rays except the scanning part of the patient in the scanning hole can be shielded; the X-ray shielding device has the advantages that by arranging the shielding before the radiation shielding and the shielding after the radiation shielding, the X-ray is ensured to be effectively shielded at the two ends of the scanning hole;

3. the design of the angle adjustable headrest and the transformation of the small angle range of the head of the patient are adopted to obtain scanning images at different angles; the scanning frame can swing back and forth at a larger angle by arranging the electric push rod, so that scanned images at different angles can be obtained.

the device comprises a scanning frame 1, a scanning deck chair 2, an electric push rod 3, a support 4, an angle-adjustable headrest 5, a rotating shaft 6, a radiation shielding shell 7, a shield 8 before radiation shielding, a shield 9 after radiation shielding and a scanning hole 10.

Detailed Description

The present invention will be described in further detail with reference to examples.

The embodiment provides a head CT machine for emergency treatment, as shown in fig. 1 and 2, which includes a support 4, a scanning frame 1 and a scanning couch 2, wherein a rotating shaft 6 is connected between the support 4 and the scanning frame 1, and the two rotating shafts 6 are respectively located at the left and right sides of the scanning frame 1. An angle-adjustable headrest 5 is arranged on one side of the scanning couch 2 close to the scanning frame 1 (the driving structure of the angle-adjustable headrest 5 can be referred to patent 201720504493.1), a scanning hole 10 is arranged on the scanning frame 1, and the scanning hole 10 can just accommodate the angle-adjustable headrest 5. The movement mode of the angle-adjustable headrest 5 in this embodiment is up-and-down swing, the support 4 is provided with an electric push rod 3 for swinging the scanning frame 1, and the telescopic end of the electric push rod 3 is fixedly connected with the bottom center of the scanning frame 1. The support 4 is also provided with a power supply for driving the angle-adjustable headrest 5, the scanning frame 1 and the electric push rod 3 to operate, the power supply can be a power generation system or a lithium battery, the scanning frame 1 is only used for scanning the head, so that the consumed power is low, and the generated energy of the power generation system or the capacity of the lithium battery can be relatively low.

The scanning frame 1 of this embodiment is wrapped by the radiation shielding shell 7, which can ensure that all X-rays are shielded except for the scanning position of the patient in the scanning hole 10, and further, radiation-proof materials are filled between the radiation shielding shell 7 and the scanning frame 1 for enhancing the shielding function. Meanwhile, as shown in fig. 4 and 5, the two ends of the scanning frame 1, which are located in the scanning hole 10, are respectively provided with a radiation shield front shield 8 and a radiation shield rear shield 9, the radiation shield front shield 8 and the radiation shield rear shield 9 are both connected with the outer surface of the radiation shield shell 7, and the radiation shield front shield 8 and the radiation shield rear shield 9 are arranged to ensure that the X-ray is effectively shielded at the two ends of the scanning hole 10.

The working principle of this embodiment is as follows: the patient lies on the scanning couch 2, the head of the patient is placed on the angle-adjustable headrest 5 (when the patient is mounted on an emergency ambulance or on a rescue site, the angle-adjustable headrest 5 is already positioned in the scanning hole 10), the scanning of the head of the patient is realized through the scanning frame 1, and the head of the patient needs to be kept attached to the angle-adjustable headrest 5 in the scanning process. When the scanning head portrait with different angles needs to be obtained, the position of the patient can be changed by adjusting the headrest 5 through the vertical small-amplitude swinging angle, and as shown in fig. 4, a space for the movement of the headrest 5 with the adjustable angle is arranged on the front shield 8 of the radiation shield.

To solve this drawback, the gantry 1 can be swung around the rotation shaft 6 by extending or shortening the electric push rod 3, as shown in fig. 3, and the dotted line "X" in the figure is a schematic view of the swinging of the gantry 1. In this way, since the swing range of the gantry 1 is large and the gantry 1 itself has a certain size, the installation space is required to have a sufficient reserved space.

The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
