Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an automatic protective device for CT examinations. Background Technology

[0002] CT scans have advantages such as fast scanning time, non-invasive examination, clear imaging, and high resolution, and are gradually becoming a commonly used examination method. Compared with ordinary X-rays, CT scans expose patients to a greater amount of radiation, so it is especially important to take good radiation protection measures.

[0003] Chinese Patent No. CN 220236899 U discloses a protective device for CT examinations, including a bed with an L-shaped groove on its side and rollers slidably connected within the groove. This invention utilizes an L-shaped groove, a support plate, and radiation shielding plates to form a conveniently assembled and stored protective device for CT examinations. By sequentially pulling multiple U-shaped radiation shielding plates slidably mounted on the L-shaped groove, the stacked radiation shielding plates are moved from the side of the bed to the top surface. This causes the rollers, mounted on a fixed block with connecting columns, to roll along the inner side of the L-shaped groove and disengage from the support plate. At this point, by adjusting the position or combining the number of U-shaped radiation shielding plates according to the patient's non-examination areas, each adjacent pair of U-shaped radiation shielding plates is connected by splicing grooves and splicing strips. This allows the protective device composed of multiple U-shaped radiation shielding plates to form a whole or be disassembled into multiple unit protective structures, offering flexibility and strong operability.

[0004] However, in the above technical solution, multiple U-shaped radiation shielding plates that are slidably installed on the L-shaped chute are pulled in sequence to move the stacked radiation shielding plates from the side of the bed to the top of the bed. Although this can reduce the obstruction to the patient climbing the bed, it requires multiple transfers of the protective device to protect the patient's body, which adds more steps to its use and storage. Utility Model Content

The support frame 2 is connected to the examination bed body 1, and the support plate 3 is disposed within the support frame 2. Multiple limiting posts are provided below the support plate 3 to limit the movement range of the support plate 3. The headrest is connected to the support plate 3, and the two ends of the multiple elastic components 6 are respectively connected to the support plate 3 and the examination bed body 1. The elastic components 6 are selected from, but are not limited to, springs. Multiple protective components 4 are slidably connected to both sides of the support frame 2, and each protective component 4 is connected to a trigger plate 5. When the radiation protection component is in use, the downward movement of the support plate 3 will cause the trigger plate 5 to drive the protective components 4 to rotate, and the two protective components 4 will approach each other and splice together to form a U-shaped protective cover.

[0022] Example 2

[0023] like Figures 2-4 As shown, the present invention proposes an automatic protection device for CT examination. Compared with Embodiment 1, this embodiment describes the detailed structure of the radiation protection component. The radiation protection component also includes a first multi-stage telescopic rod 7. The number of the first multi-stage telescopic rods 7 corresponds to the number of elastic elements 6. The two ends of the first multi-stage telescopic rods 7 are respectively connected to the examination bed body 1 and the support frame. The elastic elements 6 are sleeved on the outside of the first multi-stage telescopic rods 7.

[0024] In an optional embodiment, the protective member 4 consists of a blocking member 8 and a connecting block 9. The blocking member 8 has an arc-shaped cross-section. One end of the blocking member 8 is connected to the connecting block 9. The connecting block 9 is slidably connected to the support frame 2. The trigger plate 5 is connected to the connecting block 9. The trigger plate 5 is normally in an inclined state.

[0025] In an optional embodiment, two parallel sliding grooves 10 are provided on the support frame 2, and each sliding groove 10 is connected to a guide rod 11, which is slidably connected to the connecting block 9.

[0026] In an optional embodiment, the blocking member 8 consists of a fixed plate 12, a movable plate 13, a second multi-stage telescopic rod 14, and a radiation shielding cloth 15. The fixed plate 12 is connected to the connecting block 9, the movable plate 13 is arranged parallel to the fixed plate 12, the two ends of the second multi-stage telescopic rod 14 are respectively connected to the fixed plate 12 and the movable plate 13, and the radiation shielding cloth 15 is connected between the fixed plate 12 and the movable plate 13. The radiation shielding cloth 15 is selected from, but is not limited to, tungsten / bismuth-based composite materials.

[0027] In an optional embodiment, the fixed plate 12 and the movable plate 13 are both connected to magnetic components 16 on the side away from each other, and the adjacent blocking components 8 are magnetically connected; after the adjacent blocking components 8 are connected, a protective cover with a large coverage area can be formed. The magnetic components 16 can reduce the gap when the two are combined. The magnetic components 16 are selected from, but are not limited to, magnets.

[0028] In an optional embodiment, the diameters of the two blocking members 8 on the two sides of the examination bed body 1 are different, the outer diameter of one blocking member 8 is the same as the inner diameter of the other blocking member 8, and the blocking members 8 are staggered; the staggered blocking members 8 can prevent the gap between them from causing leakage when they rotate and splice together to form an inverted U-shaped protective cover.

[0029] In summary, when using this utility model, after the patient removes metal objects from their body, they sit on the examination bed body 1 and gradually lie down. While sitting on the examination bed body 1, they come into contact with the support plate 3. After bearing weight, the support plate 3 compresses the elastic element 6 and the length of the first multi-stage telescopic rod 7. The support plate 3 then moves down and contacts the trigger plate 5. The trigger plate 5 is driven to rotate around the guide rod 11. The two W-shaped blocking elements 8 rotate synchronously through the connecting block 9, changing from a W shape to an n or inverted U shape, thus assembling into a complete protective structure. The shield is placed over the human body to protect it. The radiation shielding cloth 15 is used to prevent other parts of the patient's body from being affected by radiation. When it is necessary to expand the protection range, the movable plate 13 is pulled to stretch the second multi-stage telescopic rod 14 so that it moves horizontally. The increased distance between the movable plate 13 and the fixed plate 12 allows the radiation shielding cloth 15 to be fully unfolded to expand the protection range. Depending on the needs of the detection location, the blocking member 8 can also be pushed to drive the connecting block 9 to move horizontally along the guide rod 11, and the blocking member 8 can be placed on different parts of the human body for protection.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
