Description

Technical Field

[0001] This invention relates to the field of X-ray protection technology, and more specifically, to an indoor radiation protection system and its method of use. Background Technology

[0002] Bedside radiography machines are medical devices used to take X-rays at the bedside for critically ill patients, patients with limited mobility, and patients with complex injuries. For example, the mobile DR (Digital Radiography) X-ray machines purchased and used in most hospitals today are specifically designed for bedside radiography.

[0003] When taking X-rays at the bedside, patients can wear lead aprons for protection. However, there are many other beds in the ward. How to avoid radiation exposure to patients in other beds during bedside X-rays? Currently, the main product used is the portable lead screen, a common protective device. It generally uses lead rubber or lead plates with a lead equivalent of ≥0.5 mmPb as the shielding material, fixed with a metal frame around the perimeter, and equipped with casters with brakes at the bottom for easy movement and positioning. In use, it can be placed between the examination bed and the adjacent bed to form a shielding barrier, blocking the scattering of X-rays. Some portable lead screens are also equipped with lead glass observation windows, allowing medical staff to observe the patient's condition while ensuring the protective effect.

[0004] However, these portable lead screens take up a lot of floor space in the wards, which can easily lead to overcrowding and inconvenience. Our hospital has collaborated with an external R&D company to develop an indoor protection system that can be used in wards. By referring to the light-blocking concept of curtains, we have customized and developed this patented indoor protection system to avoid directly occupying floor space. Summary of the Invention

[0011] Furthermore, the present invention states that the crossbar assembly includes a crossbar, a suspension rod, a fixed shaft, a short rack, and a turntable. The suspension rod is slidably mounted on the crossbar, and the bottom end of the suspension rod is detachably fixed to the lead screen assembly. The fixed shaft is fixed to the end of the crossbar, and the turntable is rotatably mounted on the fixed shaft with clearance fit. The short rack is vertically fixed to the outside of the turntable.

[0012] Furthermore, the present invention states that the suspension rod includes a rod body, a sliding body, and a detachable disc. The sliding body is slidably connected to the crossbar. The top end of the rod body is fixed to the sliding body, and the bottom end is fixedly connected to the detachable disc. The detachable disc is detachably fixed to the lead screen assembly by bolts.

[0013] Furthermore, the present invention includes: the lead screen assembly comprising a lead screen panel and a central rotating connector; the lead screen panel having arc-shaped mounting grooves on the left and right sides, and rotating holes within the arc-shaped mounting grooves; the central rotating connector being racetrack-shaped, with a first shaft and a second shaft at its top; the first shaft and the second shaft being rotatably mounted within the rotating holes; and a buckle plate, also racetrack-shaped, comprising a third shaft and a insert rod; the insert rod being inserted and fixed to the bottom surface of the lead screen panel; and the third shaft being rotatably mounted within the rotating hole at the bottom end of the central rotating connector.

[0035] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0036] An indoor radiation protection system is designed for use in hospital wards during renovations. The system is activated when a mobile DR (Digital Radiography) X-ray machine is taking X-rays of a patient in bed, providing shielding for the patient in the adjacent bed. The structural schematic diagram is shown below. Figure 1 As shown, the system comprises three main parts: a double-track assembly 100, a crossbar assembly 200, and a lead screen assembly 300. The double-track assembly 100 and the crossbar assembly 200 are arranged perpendicularly to each other; the lead screen assembly 300 is located below the crossbar assembly 200, and the crossbar assembly 200 is slidably mounted on the double-track assembly 100. The lead screen assembly 300 achieves position adjustment by sliding the crossbar assembly 200 against the double-track assembly 100. The connection relationships and structure between the mechanical components are described in detail below.

[0037] Combination Figures 1-3As shown, the dual-track assembly 100 includes two sets of parallel transverse slide rails 101. The transverse slide rails 101 can be made of plastic or metal. Each transverse slide rail 101 has a first slide rail housing 1011 and a first T-shaped groove 1012. The first T-shaped groove 1012 is used to allow for the sliding installation of the crossbar assembly 200. Furthermore, the first slide rail housing 1011 has a vertical opening 1013 for adjusting the longitudinal height of the crossbar assembly 200.

[0038] The dual-track assembly 100 is also provided with multiple sets of parallel longitudinal slide rails 102. The longitudinal slide rails 102 can be made of plastic or metal. The processed longitudinal slide rails 102 have a second slide rail housing 1021 and a second T-shaped slide groove 1022. The top of the second T-shaped slide groove 1022 is connected to the vertical opening 1013. The second T-shaped slide groove 1022 is used to realize the longitudinal height adjustment of the crossbar assembly 200.

[0039] Combination Figure 1 , Figure 6 and Figure 7 As shown, since it is difficult to achieve height positioning and fixation when the crossbar assembly 200 is adjusted in the longitudinal direction, the structure of the second slide rail housing 1021 in this system is configured such that a rotating mechanism housing 1031, a rotating shaft 1032, a rack mounting body 1033, a rack 1034, a rotating shaft limiting rod 1035, and a limiting rod mounting block 1036 are provided on its back. The housing 1031 of the rotating mechanism is made of plastic or metal. Its internal space is used to install the rotating structure. The rotating shaft 1032 and the rack mounting body 1033 in the rotating structure are coaxially arranged. The rack 1034 is installed on the outer periphery of the upper and lower rack mounting bodies 1033. The rotating shaft 1032 is rotatably mounted on the housing 1031 of the rotating mechanism. The rotating shaft 1032 is provided with a positioning hole. The limiting rod mounting block 1036 is fixed on the outer surface of the housing 1031 of the rotating mechanism. The rotating shaft limiting rod 1035 is movably inserted through the limiting rod mounting block 1036 and inserted into the positioning hole on the rotating shaft 1032 to realize the rotational positioning of the rotating shaft 1032.

[0040] In use, the two ends of the crossbar assembly 200 slide downward along the second T-shaped slide groove 1022 and engage with the rack 1034. When the crossbar assembly 200 slides downward in the second T-shaped slide groove 1022, gravity causes the rack 1034 to rotate around the rack mounting body 1033. The rack mounting body 1033 drives the rotating shaft 1032 to rotate. When positioning is required, the rotating shaft limiting rod 1035 is inserted into the positioning hole opened on the rotating shaft 1032 to restrict the rotation of the rotating shaft 1032, thereby restricting the movement of the rack 1034 and realizing the height positioning of the crossbar assembly 200.

[0041] Combination Figure 1 , Figure 4 , Figure 5 As shown, the crossbar assembly 200 includes a crossbar 201, a suspension rod 202, a fixed shaft 203, a short rack 204, and a turntable 205. The suspension rod 202 is slidably mounted on the crossbar 201, and the bottom end of the suspension rod 202 is detachably fixed to the lead screen assembly 300. The fixed shaft 203 is fixed to the end of the crossbar 201. The turntable 205 is rotatably mounted on the fixed shaft 203 with clearance fit. The short rack 204 is vertically fixed to the outside of the turntable 205, and the short rack 204 is used to cooperate with the rack 1034, or in other words, to mesh.

[0042] To enable detachable installation between the crossbar assembly 200 and the lead screen assembly 300, the suspension rod 202 in this embodiment includes a rod body 2021, a sliding body 2022, and a detachable disc 2023. The sliding body 2022 is slidably connected to the crossbar 201. The top end of the rod body 2021 is fixed to the sliding body 2022, and the bottom end is fixedly connected to the detachable disc 2023. The detachable disc 2023 is detachably fixed to the lead screen assembly 300 by bolts. Figure 1 As shown, the top of the lead screen assembly 300 is also equipped with a rod and a detachable plate. The two detachable plates are fixed by bolts to achieve a detachable connection.

[0043] Combination Figure 1 , Figure 8 and Figure 9 As shown, the lead screen assembly 300 includes a lead screen panel 301 and an intermediate rotating connector 302. The lead screen panel 301 has arc-shaped mounting grooves 3011 on its left and right sides, and rotating holes 3012 within the arc-shaped mounting grooves 3011. The intermediate rotating connector 302 is racetrack-shaped, and a first shaft 3021 and a second shaft 3022 are provided at its top. The first shaft 3021 and the second shaft 3022 are rotatably installed within the rotating holes 3012. It also includes a buckle plate 303, which is racetrack-shaped and includes a third shaft 3031 and a plug rod 3032. The plug rod 3032 is inserted and fixed to the bottom surface of the lead screen panel 301, and the third shaft 3031 is rotatably installed within a rotating hole 3023 at the bottom end of the intermediate rotating connector 302. Each intermediate rotating connector 302 is equipped with a pair of buckle plates 303 fixed from the bottom surface.

[0044] The lead shielding plate connection structure design of this invention primarily prevents X-rays from entering through the gaps at the connection points, effectively avoiding any gaps in the protection of ordinary connection structures. The intermediate rotating connector 302 can be made of a material or structure with protective properties, and can refer to the structural design of the lead shielding plate 301 in the prior art, ensuring a lead equivalent of ≥0.5mmPb to meet the protection requirements.

[0045] In another embodiment, the lead screen assembly 300 is configured as one or two sets. This configuration allows for two sets of lead screen assemblies 300 on a single crossbar assembly 200, with the two sets of lead screen assemblies 300 located on opposite sides of the crossbar assembly 200, achieving counter-pull protection. If only one set of lead screen assembly 300 is used, it provides side-pull protection.

[0046] In another embodiment, the crossbar assembly 200 is configured as one or two sets. The reason for this configuration is that when protection is required on both sides of the hospital bed (usually protection is only required on the side where the mobile DR (Digital Radiography) X-ray machine is taking pictures), two sets of crossbar assemblies 200 can be added to achieve protection on both sides.

[0047] Furthermore, based on the above system structure, the method of using the indoor radiation protection system of the present invention includes the following steps:

[0048] The assembled lead screen components are slid forward along the double-track components via the crossbar components.

[0049] After sliding to the preset position, the lead screen component is positioned next to the bedside filming machine to block the filming direction;

[0050] Adjust the height of the lead screen assembly downwards along the longitudinal slide rail;

[0051] After sliding to the preset height, adjust to the appropriate height and then use the pivot limit rod to limit the pivot and restrict the height of the lead screen component.

[0052] After filming is completed, the storage work is done in reverse.

[0053] The indoor radiation protection system of the present invention is simple to use and does not occupy ground space. The ground space can be used to temporarily place more other medical equipment and facilities, which facilitates the work of medical staff.

[0054] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
