Description

Technical Field

[0001] The utility model relates to the technical field of radiation protection, in particular to a multiple radiation protection device. Background Art

[0002] DR examination belongs to the examination items of radiology. DR examination is also called digital X-ray photography. Through digital systematization and computer processing, the picture becomes clearer. It is widely used in clinical practice, especially in primary hospitals. When performing DR imaging, it is generally prevented from X-ray radiation by wearing protective clothing such as lead suits. A medical DR radiation protection device is recorded in the patent with the existing patent announcement number CN219126417U. When the patient needs to be tested, the drive motor drives the screw to rotate toward one side, so that the nuts on both sides drive the cover plates away from each other, so as to perform radiation detection through the DR flat plate of the medical DR mechanism. When the detection is completed, the drive motor drives the screw to rotate toward the other side, so that the nuts on both sides drive the cover plates closer to each other, so as to close the DR flat plate. When the cover plates on both sides are moved in the direction away from each other, the gear rotates by meshing with the rack plate, so that the cover plates on both sides and the sealing plate are enclosed on one side of the medical DR mechanism to form a detection cavity, which effectively avoids the radiation of rays to both sides. However, the above device cannot be adjusted according to the height of the patient, and its universality is low.

[0003] Based on this, a multiple radiation protection device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] In one embodiment, Figure 1-Figure 5 As shown, a multiple radiation protection device includes a base 11, a first adjustment frame 12 is fixedly installed on the left side of the upper end of the base 11, and a second adjustment frame 13 corresponding to the first adjustment frame 12 is fixedly installed on the right side of the lower end of the base 11; a shielding structure is arranged between the first adjustment frame 12 and the second adjustment frame 13 for adjusting the X-ray irradiation area; an adjustment structure is arranged on the upper end of the first adjustment frame 12 for adjusting the height of the shielding structure.

[0026] In this embodiment, when a patient needs to be tested, the medical staff adjusts the height of the shielding structure using the adjustment structure according to the patient's height, and then adjusts the X-ray irradiation area through the shielding structure according to the patient's test position.

[0027] In one embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the shielding structure includes an upper support plate 17 and a lower support plate 21, and the upper support plate 17 and the lower support plate 21 are arranged between the first adjustment frame 12 and the second adjustment frame 13, and the upper support plate 17 is located above the lower support plate 21, and the left and right ends of the upper support plate 17 are respectively fixedly installed with the first adjustment block 16 and the second adjustment block 19, and the left and right ends of the lower support plate 21 are respectively fixedly installed with the third adjustment block 20 and the fourth adjustment block 23, the first adjustment block 16 and the third adjustment block 20 are slidably connected to the inner wall of the first adjustment frame 12, the second adjustment block 19 and the fourth adjustment block 23 are slidably connected to the inner wall of the second adjustment frame 13, and a shielding component is arranged between the upper support plate 17 and the lower support plate 21.

[0028] Through the limiting effect of the first adjusting frame 12 on the first adjusting block 16 and the third adjusting block 20, and through the limiting effect of the second adjusting frame 13 on the second adjusting block 19 and the fourth adjusting block 23, the lower support plate 21 and the upper support plate 17 can only move up and down along the first adjusting frame 12 and the second adjusting frame 13, and the X-ray irradiation area is adjusted through the shielding component between the upper support plate 17 and the lower support plate 21.

[0029] In one embodiment, Figure 3 and Figure 4 As shown, the shielding assembly includes a slide groove 18 and a movable groove 22, the slide groove 18 is opened at the lower end of the upper support plate 17, the movable groove 22 is opened at the upper end of the lower support plate 21, and a shielding motor 24 is installed at the right end of the lower support plate 21, and the output end of the shielding motor 24 extends to the inside of the movable groove 22 and is fixedly connected to a bidirectional screw 25, and both ends of the outer side wall of the bidirectional screw 25 are threadedly connected to a movable block 26, and a shielding plate 27 is fixedly installed on the upper end of the movable block 26, and a slider 28 is fixedly installed on the upper end of the shielding plate 27, and the outer wall of the slider 28 is slidably connected to the inner wall of the slide groove 18.

[0030] The bidirectional screw 25 is driven to rotate by the shielding motor 24. Since the threads at both ends of the bidirectional screw 25 are in opposite directions, the movable blocks 26 at both ends of the bidirectional screw 25 move synchronously in relative or opposite directions. A shielding plate 27 is fixedly installed on the upper end of the movable block 26. When it is necessary to test the patient, the shielding motor 24 drives the bidirectional screw 25 to rotate toward one side, so that the shielding plates 27 at both ends of the bidirectional screw 25 move away from each other, so as to perform radiation detection through the DR detection equipment. When the detection is completed, the shielding motor 24 drives the bidirectional screw 25 to rotate toward the other side, so that the shielding plates 27 at both ends of the bidirectional screw 25 move close to each other, thereby closing the detection area and effectively limiting the radiation of the equipment.

[0031] In one embodiment, Figure 1 , Figure 3 and Figure 5 As shown, the adjustment structure includes an adjustment motor 14 and two limit rods 29. The adjustment motor 14 is installed on the upper end of the first adjustment frame 12. The output end of the adjustment motor 14 extends to the inside of the first adjustment frame 12 and is fixedly connected to the adjustment screw 15. The outer side walls of the adjustment screw 15 are respectively threadedly connected to the first adjustment block 16 and the third adjustment block 20. The two limit rods 29 are symmetrically fixed on the front and rear sides of the right end of the second adjustment frame 13. The outer side walls of the two limit rods 29 are slidably connected to the second adjustment block 19 and the fourth adjustment block 23.

[0032] According to the patient's height and detection position, the adjusting motor 14 is used to drive the adjusting screw 15 to rotate. Due to the limiting effect of the first adjusting frame 12 on the first adjusting block 16 and the third adjusting block 20, and the limiting effect of the second adjusting frame 13 on the second adjusting block 19 and the fourth adjusting block 23, the adjusting screw 15 drives the upper support plate 17 and the lower support plate 21 to move up and down during the rotation process, thereby adjusting the protective height of the shielding plate 27.

[0033] In one embodiment, Figure 4 As shown, the cross-section of the slide groove 18 and the slider 28 is a T-shaped structure.

[0034] By designing the cross-sections of the slide groove 18 and the slider 28 to be T-shaped, it is ensured that the slider 28 slides inside the slide groove 18 and is not easy to fall off, thereby ensuring that the shielding component can operate stably.

[0035] In one embodiment, Figure 2 and Figure 3 As shown, universal wheels are installed at the corners of the lower end of the base 11.

[0036] By installing universal wheels at the lower corners of the base 11, it is convenient for medical staff to move the device and facilitate transportation.

[0037] In one embodiment, Figure 2 and Figure 3 As shown, a shielding plate 30 is vertically fixed to one side of the shielding plate 27 .

[0038] By vertically fixing the shielding plate 30 on one side of the shielding plate 27, the shielding plates 30 on both sides and the shielding plate 27 enclose a detection cavity to prevent the DR detection device from radiating toward both sides.

[0039] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the shielding plate 27 and the shielding plate 30 are both made of lead plates.

[0040] The aluminum plate has excellent durability and corrosion resistance, a long service life, and the aluminum plate has a radiation protection effect, which can prevent the rays of the DR detection equipment from causing harm to the patient's body and is beneficial to the patient's health.

[0041] The above embodiment discloses a multiple radiation protection device, wherein when a patient needs to be tested, the medical staff drives the adjusting screw 15 to rotate by adjusting the motor 14 according to the patient's height. Due to the limiting effect of the first adjusting frame 12 on the first adjusting block 16 and the third adjusting block 20, and the limiting effect of the second adjusting frame 13 on the second adjusting block 19 and the fourth adjusting block 23, the adjusting screw 15 drives the upper support plate 17 and the lower support plate 21 to move up and down during the rotation process, thereby adjusting the protection height of the shielding plate 27, and then the bidirectional screw 25 is driven to rotate toward one side by the shielding motor 24, so that the shielding plates 27 at both ends of the bidirectional screw 25 are away from each other, so as to pass the radiation of the DR detection equipment for detection. When the detection is completed, the shielding motor 24 drives the bidirectional screw 25 to rotate toward the other side, so that the shielding plates 27 at both ends of the bidirectional screw 25 are close to each other, thereby closing the detection area and effectively limiting the radiation of the equipment.

[0042] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
