Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a protective structure for shielding CT radiation. Background Art

[0002] As we all know, the cathode tungsten filament of the CT machine's X-ray tube is heated to generate an electron flow. The emitted electrons are accelerated by the high-voltage electric field at the two poles of the tube, and then bombard the anode target at high speed, causing the bremsstrahlung effect and generating X-rays. The CT machine uses this X-ray to scan and image the human body, and medical mobile CT machines are sometimes used in emergency rooms, operating rooms, wards, ambulances, and ships. These places do not have the protection of shielded rooms, so the CT machine itself needs to be shielded by X-rays. Common CT machines are equipped with a scanning hole, and the patient is usually scanned in the scanning hole, but the scanning hole is generally larger in diameter, which means that there will still be a large gap after the patient enters the scanning hole, so the radiation will be emitted from the gap, which will pose a threat to the health of external operators. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a self-shielding structure for protecting CT radiation, which can prevent the radiation inside the CT machine from escaping outward through the scanning hole, thereby effectively protecting external operators.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Please attend Figure 1 and Figure 2 The utility model discloses a protective structure for shielding CT radiation, comprising a first positioning column 1 and a second positioning column 2, wherein a longitudinally slidable crossbeam 3 is arranged between the first positioning column 1 and the second positioning column 2, the first positioning column 1 is provided with a driving assembly 4 for driving the crossbeam 3 to move up and down, a downwardly extending protective material layer 5 is connected to the bottom of the crossbeam 3, the protective material layer 5 comprises a first protective material layer 51 and a second protective material layer 52, the first protective material layer 51 is detachably connected to the crossbeam 3, the second protective material layer 52 comprises a plurality of second protective material layers 52, and the plurality of second protective material layers 52 are detachably connected to the lower part of the first protective material layer 51. When in use, the first positioning column 1 and the second positioning column 2 are respectively installed on both sides of the scanning hole of the CT machine. In order to facilitate the movement of the beam 3, the first sliding groove 11 and the second sliding groove 12 are respectively opened on the opposite sides of the first positioning column 1 and the second positioning column 2. When the patient is tested, the driving component 4 drives the beam 3 to move downward until the second protective material layer 52 is moved to the patient's body. At this time, the first protective material layer 51 and the second protective material layer 52 will seal the scanning hole of the CT machine, which can effectively reduce the radiation inside the CT machine from being emitted outward through the scanning hole, thereby effectively protecting external operators.

[0022] In order to facilitate installation and disassembly, in this embodiment, a groove 31 is provided on the side of the crossbeam 3 facing the first protective material layer 51, and a plurality of hanging rings 311 are provided in the groove 31. A plurality of hooks 511 corresponding to the plurality of hanging rings 311 are provided on the top of the first protective material layer 51. During installation, it is only necessary to hang the hook 511 on the hanging ring 311 in the groove 31. After use, the hook 511 can be taken out of the hanging ring 311 to complete the disassembly, and storage is also more convenient. A plurality of Velcro burr surfaces 512 are longitudinally spaced and distributed on one side of the first protective material layer 51, and a Velcro burr surface 521 matching the Velcro burr surface 512 is provided on the side of the second protective material layer 52 corresponding to the first protective material layer 51. In this embodiment, the second protective material layer 52 is in the shape of a long strip, so two Velcro bristle surfaces 512 are provided. When in use, the second protective material layer 52 is first bonded side by side to one of the Velcro bristle surfaces 512. Since a certain gap will be generated between several second protective material layers 52, in order to achieve a better protective effect, part of the second protective material layer 52 can be bonded to another Velcro bristle surface 512 to close the gap between the second protective material layers 52 bonded to one of the Velcro bristle surfaces 512, which has a better effect. It should be noted that in this embodiment, the first protective material layer 51 and the second protective material layer are both lead curtains, so the first protective material layer 51 and the second protective material layer 52 are both flexible. In order to prevent the first protective material layer 51 from shaking when installing or removing the second protective material layer 52, a limiting cross bar 7 is provided at the bottom of the first protective material layer 51, and the two ends of the limiting cross bar 7 are respectively abutted against the first slide groove 11 and the second slide groove 12. When the second protective material layer 52 needs to be installed, the first protective material layer 51 can be limited forward and backward by the limiting cross bar 7 to prevent the first protective material layer 51 from sliding, making installation easier.

[0023] When the patient needs to enter the CT machine for examination, the crossbeam 3 needs to be raised so that the protective material layer 5 can be moved from the position of the scanning hole of the CT machine. In this embodiment, the driving assembly 4 includes a driving device 41, a threaded rod 42 and a threaded sleeve 43. The driving device 41 is arranged on the first positioning column 1, the threaded rod 42 is longitudinally rotatably connected to the first slide groove 11, the output end of the driving device 41 is transmission-connected to the threaded rod 42, the threaded sleeve 43 is threadedly connected to the outside of the threaded rod 42, and the threaded sleeve 43 is fixedly connected to one end of the crossbeam 3. Specifically, the driving device 41 is arranged at the top of the first slide groove 11, one end of the threaded rod 42 is fixedly connected to the output end of the driving device 41, the other end of the threaded rod 42 abuts against the bottom of the first slide groove 11, and the threaded sleeve 43 is fixedly connected to one end of the crossbeam through a connecting rod. When the driving device 41 rotates, the threaded rod 42 is driven to rotate. At the same time, since the threaded sleeve 43 is threadedly connected to the threaded rod 42, when the threaded rod 42 rotates, the threaded sleeve 43 will move along the axial direction of the threaded rod 42, thereby driving the crossbeam 3 to move. In this embodiment, the driving device 41 is a driving motor. In order to control the driving device 41, a controller 8 is provided on the front side of the first positioning column 1. The controller 8 is electrically connected to the driving device 41, and the rotation of the driving motor can be controlled by the controller 8. When the patient needs to enter the CT machine, the driving device 41 is started by the controller 8 to drive the crossbeam 3 to move upward. When the patient enters the CT machine, the driving device 41 is started by the controller 8 to make the crossbeam move downward until the second protective material layer 41 contacts the patient's body. At this time, the first protective material layer 51 and the second protective material layer 52 can completely close the scanning hole.

[0024] When the cross beam 3 moves under the driving action of the driving assembly 4, in order to cooperate with the movement of the cross beam 3, in this embodiment, a sliding assembly 6 is also included in the second column 2, and the sliding assembly 6 includes a guide rod 61 and a guide block 62. The guide rod 61 is longitudinally arranged in the second slide groove 21, and the guide block 62 is slidably assembled on the outside of the guide rod 61. The guide block 62 is fixedly connected to the other end of the cross beam 3. Specifically, the two ends of the guide rod 61 are respectively fixedly connected to the top and bottom of the second slide groove 21, and the end of the cross beam 3 is fixedly connected to the guide block 62 through a connecting rod. When the cross beam 3 moves up and down, since the cross beam 3 is fixedly connected to the guide block 62, the guide block 62 will slide up and down along the axial direction of the guide rod 61. By setting the guide rod 61, the guide block 62 can be longitudinally limited, which is more stable during the sliding process.

[0025] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the utility model.
