Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a helmet-type shielding and protective device for CT scanners. Background Technology

[0002] CT is a medical imaging technology whose core principle is to use precisely calibrated X-ray, gamma-ray, or ultrasound beams, combined with highly sensitive detectors, to perform multi-angle continuous tomographic scans of specific parts of the human body. This technology can quickly generate high-resolution cross-sectional images, significantly improving the accuracy of lesion identification, and is widely used in fields such as tumor detection, bone disease diagnosis, and vascular imaging.

[0003] Chinese Patent No. CN211484628U discloses a helmet-type shielding protection device for CT scanners, including a front fixing ring plate. A rear fixing ring plate is integrally machined around the rear side of the front fixing ring plate. A shielding plate is bolted between the top of the rear side of the front fixing ring plate and the top of the front side of the rear fixing ring plate. A first strong adhesive is bonded to the top of both the front and rear sides of the shielding plate, and the surface of the first strong adhesive is bonded to the rear side of the front fixing ring plate and the front side of the rear fixing ring plate, respectively. Through the arrangement of the front fixing ring plate, rear fixing ring plate, shielding plate, and first strong adhesive, this helmet-type shielding protection device for CT scanners has the advantages of simple structure and easy cleaning. It solves the problems of current shielding protection devices being complex in structure, cumbersome in operation, difficult to clean, and prone to accumulating dirt and grime, making it difficult to maintain hygiene.

[0004] However, the above technical solution has the following shortcomings: Although the device can shield excess radiation through the shielding plate, due to the large differences in body size among different people being scanned, the bottom of the shielding plate is set higher in order to meet the usage requirements of most people, which may result in a large gap between the bottom of the shielding plate and some people, thereby reducing the shielding effect against radiation. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a helmet-type shielding protection device for CT scanners. This device can adjust the gap between the shielding plate and the person being tested according to the body shape of the person being tested, thereby further reducing the radiation effect on unscanned areas.

[0006] The present invention provides a helmet-type shielding protection device for a CT scanner, comprising a front shielding ring and an adjustment mechanism. A rear shielding ring is fitted to the rear of the front shielding ring, and three first shielding main plates and two second shielding main plates are disposed inside the front and rear shielding rings.

The first and second bevel gears are meshed together, the threaded rod and the threaded block are threadedly connected, and the guide sliders are slidably disposed inside the first shielding main plates.

[0007] Preferably, the two second shielding motherboards are located on both sides of the first shielding motherboard, and the first and second shielding motherboards are symmetrically distributed.

[0008] Preferably, a fan-shaped connecting plate is provided on the front windshield protection ring, and positioning grooves are provided inside the front windshield protection ring and the rear windshield protection ring, with the second shielding main board embedded in the positioning groove.

[0009] Preferably, the rear windshield protection ring is provided with a countersunk hole, the interior of which is provided with a fitting block, and the fitting block is provided with a screw. The screw passes through the first shielding main board and the front windshield protection ring and is threadedly connected with a nut. The nut is abutted against the front windshield protection ring.

[0010] Preferably, a first strong adhesive is provided between the front windshield protection ring and the rear windshield protection ring and the first shielding main board.

[0011] Preferably, a second strong adhesive is provided on the side of the rear windshield protection ring that is opposite to the front windshield protection ring.

[0012] Preferably, the cross-sectional shape of the guide slider is T-shaped, and the first shielding main board is provided with a groove for the guide slider to slide vertically.

[0013] Preferably, one end of the rotating shaft passes through the first shielding motherboard and is equipped with a handwheel.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model, through its first and second shielding main boards and adjustment plate, can effectively shield radiation and protect the unscanned areas of the testing personnel. Furthermore, the adjustment mechanism allows for height adjustment of the adjustment plate according to the testing personnel's body size, further enhancing the shielding effect. This achieves the goal of not obstructing the passage of testing personnel while reducing radiation exposure to the human body. It is simple and convenient to operate and has excellent practicality.

The two second shielding main boards 9 are located on both sides of the first shielding main boards 3, and the first shielding main boards 3 and the second shielding main boards 9 are symmetrically distributed.

[0023] The adjustment mechanism includes an adjustment plate 10 slidably connected to the first shielding main plate 3, a threaded block 11 disposed on the adjustment plate 10, a threaded rod 12 vertically distributed and rotatably disposed inside the first shielding main plate 3, a first bevel gear 13 coaxially disposed on the threaded rod 12, a rotating shaft 14 rotatably connected to the first shielding main plate 3, a second bevel gear 15 coaxially disposed on the rotating shaft 14, and two guide sliders 17 symmetrically distributed on the adjustment plate 10; the first bevel gear 13 and the second bevel gear 15 are meshed and connected, the threaded rod 12 and the threaded block 11 are threadedly connected, the guide sliders 17 are slidably disposed inside the first shielding main plate 3, and one end of the rotating shaft 14 passes through the first shielding main plate 3 and is provided with a handwheel 16.

[0024] The cross-sectional shape of the guide slider 17 is T-shaped, and the first shielding main board 3 is provided with a groove for the guide slider 17 to slide vertically.

[0025] In this embodiment, the first shielding main board 3, the second shielding main board 9, and the adjusting plate 10 can effectively shield radiation and protect the unscanned parts of the inspector. Furthermore, the height of the adjusting plate 10 can be adjusted according to the inspector's body size to further ensure radiation shielding. During adjustment, the handwheel 16 rotates the shaft 14, which in turn drives the second bevel gear 15.
