Description

Technical Field

[0001] This utility model belongs to the field of radiation protection equipment technology, and in particular relates to a prefabricated lead-free radiation protection device. Background Technology

[0002] In the medical field, especially in neonatal intensive care units (NICUs), incubators and radiant warmers are crucial equipment. Some premature or critically ill infants require observation and care within incubators. However, if these infants are removed from the incubator and placed in the hospital's radiology room for imaging with X-ray machines, the risk of infection increases, and their conditions worsen. Conversely, placing X-ray machines in regular patient wards, where there are no protective measures or facilities, can severely impact other sick infants and medical staff due to the radiation emitted from the machine.

[0003] To address this issue, radiation shields specifically designed for infant incubators have been introduced to the market. These shields have an opening on one side for the incubator to enter and exit, fitted with a lead curtain to prevent radiation leakage. When the infant incubator needs to be moved into the shield, staff must remove or lift the lead curtain. However, due to the weight of the lead curtain, improper handling can easily cause it to fall. Furthermore, lead is a heavy metal, and long-term exposure may lead to lead poisoning, posing potential hazards to human health and the environment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model aims to propose a prefabricated lead-free radiation protection device. This prefabricated lead-free radiation protection device solves the problem that the existing protective enclosure uses a single radiation protection curtain to close the opening, which is inconvenient to operate.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A prefabricated lead-free radiation protection device includes a housing, one side of which has an opening for an infant incubator to enter and exit.

[0007] A set of double-opening first protective door assemblies is provided at the opening of the box body. The two first protective door assemblies are respectively hinged to the left and right sides of the box body. Each first protective door assembly includes two protective doors arranged vertically and opening and closing respectively. Each protective door includes a protective curtain and a frame that drives the protective curtain to rotate. When both first protective door assemblies are closed, the protective curtains located on the left and right sides overlap horizontally. The protective curtains located vertically in each first protective door assembly overlap vertically, so that the opening of the box body is closed.

[0008] Furthermore, a bottom curtain is installed at the bottom of the enclosure to seal the bottom from the ground and prevent radiation leakage from the bottom of the enclosure.

[0009] Furthermore, a second protective door assembly that can be opened and closed vertically is hinged above the opening of the box body. When both the second and first protective door assemblies are closed, the opening of the box body is sealed.

[0010] Furthermore, the frame includes a connecting portion for hinged connection with the housing, and a horizontal portion for mounting the protective curtain, the horizontal portion being connected to the connecting portion.

[0011] Furthermore, an installation plate is provided on the frame, and a protective curtain is installed between the frame and the installation plate.

[0012] Furthermore, the two sides of the enclosure near the first protective door assembly are respectively provided with through grooves for equipment pipelines to pass through.

[0013] Furthermore, the bottom of the through groove is inclined downward, and a sealing block that can be flipped up and down is provided near the end of the first protective door assembly, while a push-pull plate that can be pushed up and down is provided away from the end of the first protective door assembly.

[0014] Furthermore, the top of the housing is provided with a beam window for confining the rays and an adjustment device for adjusting the position of the rays.

[0015] Furthermore, observation windows are provided on the top and sides of the enclosure.

[0016] Furthermore, the bottom of the box is equipped with casters around its perimeter.

[0034] like Figures 1 to 7 As shown, an assembled lead-free radiation protection device includes a housing 1, with an opening on one side for an infant incubator to enter and exit.

[0035] A set of double-opening first protective door assemblies is provided at the opening of the box 1. The two first protective door assemblies are respectively hinged to the left and right sides of the box 1. Each first protective door assembly includes two protective doors 2 arranged vertically and opening and closing respectively. Each protective door 2 includes a protective curtain 21 and a frame 22 that drives the protective curtain 21 to rotate. When both first protective door assemblies are closed, the protective curtains 21 located on the left and right sides overlap horizontally. The protective curtains 21 located vertically in each first protective door assembly overlap vertically, so that the opening of the box 1 is closed.

[0036] The prefabricated lead-free radiation protection device of this utility model realizes the entry and exit of the infant incubator and the sealing of the opening of the box body 1 through the opening and closing of a set of split first protective door components, preventing radiation from leaking into the external environment during infant examination, effectively protecting the health of other infants and medical staff in the ward. The cooperation between the protective curtain and the frame allows the device to be quickly assembled and disassembled, which is convenient for rapid deployment and adjustment in different medical scenarios.

[0037] Each protective door 2 is connected to the housing 1 via a damped hinge, and each protective door 2 can be opened and closed independently, providing greater operational flexibility. When the two first protective door assemblies are closed, the protective curtains 21 on both sides overlap left and right, and the protective curtains 21 at the top and bottom of each first protective door assembly overlap vertically to prevent radiation leakage. The protective curtains 21 are lead-free soft protective curtains, which are made of protective material sheets containing heavy metals such as tungsten and bismuth or high-molecular materials, and will not obstruct the entry and exit of wires or oxygen tubes of monitoring equipment on the infant.

[0038] In a preferred embodiment of this utility model, a bottom curtain 3 is installed at the bottom of the box 1 to seal the bottom from the ground and prevent radiation leakage from the bottom of the box 1.

[0039] In actual use, the chamber 1 is made of polymer board and has no baffle at the bottom to facilitate the entry and exit of the infant incubator. The bottom of each side panel of the chamber 1 is bolted to the bottom curtain 3 for easy installation and disassembly, preventing radiation leakage from the bottom of the chamber 1. The bottom curtain 3 is made of the same material as the protective curtain 21.

[0040] In a preferred embodiment of the present invention, a second protective door assembly 4 that can be opened and closed vertically is hinged above the opening of the box body 1. When both the second protective door assembly 4 and the first protective door assembly are closed, the opening of the box body 1 is closed.

[0041] In actual use, the second protective door assembly 4 is made of polymer board. The second protective door assembly 4 is located above the first protective door assembly and is hinged to the housing 1 via a damped hinge. The second protective door assembly 4 is separate from the first protective door assembly, which can reduce the weight of the first protective door assembly. When the infant incubator is too high, the second protective door assembly 4 can be opened to allow the incubator to pass through; otherwise, the second protective door assembly 4 does not need to be opened.

[0042] In a preferred embodiment of the present invention, the frame 22 includes a connecting part for hinged connection with the box body 1, and a horizontal part for mounting the protective curtain 21, the horizontal part being connected to the connecting part.

Both the vertical part and the horizontal part are detachably connected to the protective curtain 21, which can form a more complete protective area, effectively blocking the leakage of rays from different directions, and at the same time enhancing the installation stability of the protective curtain 21.

[0044] In a preferred embodiment of the present invention, an mounting plate 23 is provided on the frame 22, and a protective curtain 21 is installed between the frame 22 and the mounting plate 23.

[0045] In practical use, both the mounting plate 23 and the frame 22 are provided with internally threaded countersunk holes, which are threadedly connected to screws to fix the protective curtain 21. The mounting plate 23 is an inverted L-shaped mounting plate adapted to the frame 22. The screws pass through the mounting plate 23, the protective curtain 21, and the frame 22 in sequence, and are threadedly connected to the internally threaded countersunk holes. The mounting plate 23 ensures the fixation and sealing of the protective curtain 21, effectively preventing radiation leakage. The screw connection makes the installation and maintenance of the protective curtain 21 more convenient. If it is necessary to replace or maintain the protective curtain 21, simply loosen the screws; the operation is simple and quick.

[0046] In a preferred embodiment of the present invention, the two sides of the housing 1 near the first protective door assembly are respectively provided with through grooves 5 for equipment pipelines to pass through.

[0047] The bottom of the through groove 5 is inclined downward, and a sealing block 51 that can be flipped up and down is provided near the end of the first protective door assembly, and a push-pull plate 52 that can be pushed up and down is provided away from the end of the first protective door assembly.

[0048] In actual use, the bottom of the through-slot 5 is tilted downwards to facilitate the opening and closing of the sealing block 51.
