Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an X-ray radiation protection isolation device. Background Art

[0002] Medical imaging, also known as medical imaging or imaging medicine, refers to the technology and process of obtaining images of the internal tissues of the human body or a part of the human body in a non-invasive manner for medical treatment or medical research. Medical imaging has developed into a variety of imaging technology applications. Commonly used medical imaging technologies include: X-rays, computed tomography (CT, or electronic computed tomography), magnetic resonance imaging, and medical ultrasound. X-rays and computed tomography (CT, or electronic computed tomography) require a large amount of radiation during the examination process. While these rays can accurately reveal human lesions, they can also cause certain harm to human health.

[0003] Among them, X-ray examinations are usually performed on an X-ray bed. For some diseases that require long-term follow-up, the radiation generated during the X-ray examination may radiate to other unrelated parts of the human body and may cause other diseases. Therefore, radiation isolation of non-examination parts is very important.

[0004] Currently, X-ray examinations mostly involve covering the patient with a protective blanket to isolate radiation from non-examination areas. However, as the body moves during the examination, the protective blanket can easily slip off or become loosely covered, increasing the irradiation area of ​​the X-ray beam. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide an X-ray radiation protection isolation device to solve the problem in the prior art that during X-ray inspection, the protective blanket is easy to slip or not cover tightly as the body moves, which will lead to an increase in the irradiation area of ​​the X-ray beam.

[0006] The utility model is achieved through the following technical solutions:

[0007] An X-ray radiation protection isolation device includes a support assembly installed above an X-ray photography bed, a lying plate installed on the top of the support assembly, a mounting plate slidably connected to the bottom of the lying plate, and curved plates rotatably connected on both sides of the mounting plate; a protective blanket is provided above the lying plate, and the two ends of the protective blanket are respectively fixedly connected to the two curved plates; a linkage assembly is installed on the mounting plate, and the two curved plates can rotate in opposite directions at the same time under the action of the linkage assembly.

[0008] Furthermore, the linkage assembly includes two first rotating shafts and two second rotating shafts rotatably connected to the mounting plate, the two first rotating shafts are respectively located on both sides of the mounting plate and fixedly connected to the corresponding arc-shaped plate; the two second rotating shafts are fixedly connected to the first gear, the two first gears are engaged with each other, a transmission assembly is provided between the two second rotating shafts and the corresponding first rotating shafts, and the transmission connection is achieved through the transmission assembly, and the two second rotating shafts and the corresponding first rotating shafts can rotate in the same direction under the action of the transmission assembly.

[0009] Furthermore, the transmission assembly includes two transmission wheels respectively mounted on the first rotating shaft and the corresponding second rotating shaft, and a transmission belt arranged between the two transmission wheels.

[0010] Furthermore, the transmission wheel is a second gear, the transmission belt is a ring gear, and the ring gear is meshed with the second gear.

[0011] Furthermore, the support assembly includes four support rods installed on the bottom of the lying board, and the four support rods are respectively located at the four corners of the lying board.

[0012] Furthermore, a protrusion is fixedly connected to the upper surface of the mounting plate, and a dovetail groove adapted to the protrusion is opened on the bottom surface of the lying plate along the length direction of the lying plate, and the protrusion is slidably connected in the dovetail groove.

[0013] Furthermore, handles are fixedly connected to the two first rotating shafts.

[0014] Furthermore, the arc lengths of the two arc-shaped plates are not equal, and the two arc-shaped plates are staggered up and down when closed.

[0015] The beneficial effects of the present invention are:

[0016] This X-ray radiation shielding device slides a protective blanket and mounting plate along the length of a bed to the approximate location where the patient needs protection. The patient then sits on the bed and adjusts their body position so that the area requiring protection is on the blanket. After lying down, the surface of the blanket directly contacts the patient's body. At this point, one of the curved plates rotates toward the center of the bed, and the other curved plate, driven by a linkage assembly, simultaneously rotates toward the center of the bed. The protective blanket, driven by the thrust of the two curved plates, wraps around the area of ​​the patient requiring protection. Compared to existing technologies, the protective blanket is less likely to slip or become loose during body movement during an X-ray examination, reducing the area exposed to the X-ray beam.

[0030] In this solution: First, when the solution is in idle state, Figure 1 As shown, the protective blanket 4 is unfolded in a U shape above the lying board 1. When in use, the protective blanket 4 and the mounting plate 2 are first slid along the length direction of the lying board 1 to the approximate position where the patient needs protection. The patient sits on the lying board 1 and adjusts the body position so that the part that needs protection is located on the protective blanket 4. After lying down, the surface of the protective blanket 4 is in direct contact with the patient's body. At this time, one of the curved plates 3 is rotated toward the center of the lying board 1, and the other curved plate 3 is rotated toward the center of the lying board 1 at the same time under the action of the linkage component. The protective blanket 4 wraps the part of the patient that needs protection under the thrust of the two curved plates 3, as shown in FIG. Figure 2 Compared with the prior art, the protective blanket 4 will not easily slip off or become loosely covered during body movements during X-ray inspection, thus reducing the irradiation area of ​​the X-ray beam.

[0031] After the X-ray inspection is completed, one of the curved plates 3 is rotated toward the top of the lying plate 1, and the linkage assembly drives the other curved plate 3 to rotate toward the top of the lying plate 1. The protective blanket 4 is unfolded in a U shape on the lying plate 1. Figure 1 As shown, it is convenient for the patient to get up.

[0032] In this embodiment: the linkage assembly includes two first rotating shafts 5 and two second rotating shafts 6 rotatably connected to the mounting plate 2, the two first rotating shafts 5 are respectively located on both sides of the mounting plate 2, and are fixedly connected to the corresponding arc-shaped plate 3; the two second rotating shafts 6 are fixedly connected to the first gear 7, the two first gears 7 are engaged with each other, and a transmission assembly is provided between the two second rotating shafts 6 and the corresponding first rotating shafts 5, and the transmission connection is transmitted through the transmission assembly. The two second rotating shafts 6 and the corresponding first rotating shafts 5 can rotate in the same direction under the action of the transmission assembly.

[0033] In this embodiment, one of the first rotating shafts 5 is rotated, and the transmission assembly drives the corresponding second rotating shaft 6 to rotate in the same direction. The two first gears 7, which are respectively fixedly connected to the two second rotating shafts 6, mesh with each other, driving the other second rotating shaft 6 to rotate in the opposite direction. The transmission assembly drives the other first rotating shaft 5 to rotate in the same direction, causing the two curved plates 3, which are respectively fixedly connected to the two first rotating shafts 5, to rotate simultaneously toward the center or top of the lying plate 1.

[0034] In this embodiment, the transmission assembly includes two transmission wheels 8 respectively mounted on the first rotating shaft 5 and the corresponding second rotating shaft 6 , and a transmission belt 9 arranged between the two transmission wheels 8 .

[0035] In this scheme, one of the first rotating shafts 5 is rotated to drive the transmission wheel 8 installed on the first rotating shaft 5 to rotate, and under the action of friction, the transmission belt 9 arranged between the two transmission wheels 8 is driven to rotate, and under the action of friction, the transmission wheel 8 installed on the corresponding second rotating shaft 6 and the second rotating shaft 6 are driven to rotate in the same direction.

[0036] In this embodiment, the transmission wheel 8 is a second gear, and the transmission belt 9 is a ring gear, which is engaged with the second gear.

[0037] In this solution, the transmission wheel 8 and the transmission belt 9 can also be a rotating wheel and a belt that cooperate with each other. Since the transmission accuracy of the second gear and the gear ring that cooperate with each other is better than the rotating wheel and the belt that cooperate with each other, the present embodiment selects the second gear and the gear ring that cooperate with each other.

[0038] In this embodiment, the support assembly includes four support rods 10 installed at the bottom of the lying board 1 , and the four support rods 10 are respectively located at the four corners of the lying board 1 .

[0039] In this solution, the four support rods 10 are respectively located at the four corners of the lying board 1, so that the lying board 1 can be better supported.

[0040] In this embodiment, a protrusion 11 is fixedly connected to the upper surface of the mounting plate 2 , and a dovetail groove 12 adapted to the protrusion 11 is provided on the bottom surface of the lying plate 1 along the length direction of the lying plate 1 , and the protrusion 11 is slidably connected in the dovetail groove 12 .

[0041] In this solution, a protrusion 11 is fixedly connected to the upper surface of the mounting plate 2, and a dovetail groove 12 is opened on the bottom surface of the lying plate 1 along the length direction of the lying plate 1 to match the protrusion 11. The protrusion 11 is slidably connected in the dovetail groove 12. This allows the mounting plate 2 to slide more smoothly on the lying plate 1.

[0042] In this embodiment, handles 13 are fixedly connected to the two first rotating shafts 5 .

[0043] In this solution, a handle 13 is provided on the first rotating shaft 5 to facilitate the staff to rotate the first rotating shaft 5 with less effort.

[0044] In this embodiment, the arc lengths of the two arc-shaped plates 3 are not equal, and the two arc-shaped plates 3 are staggered up and down when closed.

[0045] In this embodiment, by setting the arc lengths of the two curved plates 3 to be unequal, the two curved plates 3 intersect and push the protective blanket 4 to cover the patient's protective area when closed, thereby better covering the patient's protective area. Both curved plates 3 are made of radiation-proof material, which can cooperate with the protective blanket 4 to better cover the patient's protective area.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
