Description

Technical Field

[0001] This utility model relates to the field of medical testing instrument technology, and in particular to a mobile DR protective device. Background Technology

[0002] Mobile DR can quickly acquire and confirm photographic images a few seconds after exposure, eliminating the cumbersome procedures of traditional film processing and IP board information reading. Images can be processed on-site, transmitted over the network, and printed, making it more efficient, faster, and more direct. However, when medical personnel use mobile DR to acquire images of patients' body parts, radiation is generated, especially from the image acquisition head on the mobile DR, which produces even greater radiation. Furthermore, mobile DR itself does not have radiation-blocking capabilities.

[0003] Patent CN217447822U discloses a mobile DR protective device, relating to the field of protective equipment. This application includes a mobile DR head, a buckle surrounding the mobile DR head, a protective plate assembly with a truncated hollow structure, and a fixing strip. The fixing strip is located at the top of the protective plate assembly and is used to connect the protective plate assembly to the bottom of the buckle.

[0004] The aforementioned patents still have the following technical defects: It is understood that the distance between the DR head and the lesion is usually about 100cm, and the distance will be adjusted according to different patients and different examination sites. However, the height of the above-mentioned protective components is not adjustable, which makes them not very applicable. In addition, in order to achieve a better protective effect, the protective components need to be set higher, which results in them occupying a large space. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a mobile DR protection device.

[0006] The technical solution of this utility model is a mobile DR protection device, including a mounting plate, a drive assembly and four sets of protection components;

[0007] The mounting plate is detachably mounted on the movable DR head, and a through hole is provided in the middle of the mounting plate for the movable DR head to pass through. Four sets of protective components are installed around the mounting plate. The protective components include lead curtain, take-up roller and limit roller. The take-up roller and limit roller are rotatably mounted under the mounting plate. The limit roller is located on the side adjacent to the movable DR head. The lead curtain is wrapped around the limit roller and its end is fixedly mounted on the take-up roller. The drive assembly includes a rotating handle and three sets of gear assemblies. The three sets of gear assemblies are located at any three corner positions of the mounting plate. The gear assembly includes two bevel gears. The two bevel gears are respectively mounted on the ends of the two take-up rollers on the corresponding sides and are meshed. The end of one take-up roller extends to the outside of the mounting plate and is connected to the rotating handle.

[0008] Preferably, a rectangular counterweight frame is provided below the mounting plate, and the bottom ends of the four lead curtains are respectively connected to the four sides of the rectangular counterweight frame.

[0009] Preferably, the bottom edge of the mounting plate is provided with a rectangular enclosure.

[0010] Preferably, both ends of the take-up roller are equipped with first bearings, and the first bearings are connected to the inner wall of the rectangular enclosure with a first connecting frame; at least two second bearings are installed on each of the multiple limiting rollers, and multiple annular grooves for installing the second bearings are opened on the limiting rollers. The multiple second bearings are respectively located inside the multiple annular grooves, and the second bearings are connected to the inner wall of the rectangular enclosure with a second connecting frame. The outer diameter of the second bearing is less than or equal to the outer diameter of the limiting roller.

[0011] Preferably, the two ends of the unrolled portion of the front and rear lead curtains are in contact with the inner walls of the left and right lead curtains, respectively.

[0012] Preferably, limit rings are installed at both ends of the take-up roller.

[0013] Compared with the prior art, this utility model has the following beneficial technical effects: rotating the handle drives the corresponding winding roller to rotate, thereby unwinding the lead curtain. Under the coordinated transmission of three sets of gear components, the four winding rollers rotate synchronously to achieve rapid unwinding of the lead curtain until the bottom of the lead curtain is close to the skin. This can provide closed protection around the mobile DR head, thereby accurately blocking the radiation generated by the mobile DR head during subsequent operation, effectively improving the protection effect for medical staff and other patients in the ward. The lead curtain is designed as a retractable structure, which greatly reduces the space occupied by the protective device, making the protective device more compact and concise.

[0017] Example 1

[0018] like Figures 1-3 As shown in the figure, the mobile DR protection device proposed in this embodiment includes a mounting plate 2, a drive assembly, and four sets of protection components.

[0019] Mounting plate 2 can be detachably mounted on the movable DR head 1. A through hole for the movable DR head 1 to pass through is provided in the middle of mounting plate 2. Furthermore, two fixing plates 6 are arranged side by side on mounting plate 2. The fixing plates 6 are connected to the movable DR head 1 by bolts 7. The fixing plates 6 are provided with through holes for the bolts 7 to pass through. Both ends of the outer shell of the movable DR head 1 are provided with threaded grooves that are compatible with the bolts 7.

[0020] Four sets of protective components are installed around the mounting plate 2. The protective components include a lead curtain 4, a take-up roller 8, and a limiting roller 9. The take-up roller 8 and the limiting roller 9 are rotatably mounted below the mounting plate 2. The limiting roller 9 is positioned adjacent to the moving DR head 1. The purpose of the limiting roller 9 is to limit the lead curtain 4, preventing the lower lead curtain 4 from tilting due to the excessive diameter of the lead curtain 4 being wound at the top. First bearings 13 are installed at both ends of the take-up roller 8. A first connecting frame connects the first bearing 13 to the inner wall of the rectangular enclosure 3. Multiple limiting rollers 9 are equipped with... There are at least two second bearings 14. The limiting roller 9 has multiple annular grooves for installing the second bearings 14. The multiple second bearings 14 are respectively located inside the multiple annular grooves. The second bearings 14 are connected to the inner wall of the rectangular enclosure 3 by a second connecting frame. The outer diameter of the second bearing 14 is less than or equal to the outer diameter of the limiting roller 9. The lead curtain 4 is wound around the limiting roller 9 and its ends are fixedly installed on the take-up roller 8. The two ends of the unwound parts of the front and rear lead curtains 4 are respectively in contact with the inner walls of the left and right lead curtains 4. The purpose of this arrangement is to prevent a large gap between two adjacent lead curtains 4.

[0021] The drive assembly includes a rotating handle 10 and three sets of gear assemblies. The three sets of gear assemblies are respectively located at any three corner positions of the mounting plate 2. Each gear assembly includes two bevel gears 11, which are respectively installed at the ends of two take-up rollers 8 on the corresponding sides and are meshed together. The end of one take-up roller 8 extends to the outside of the mounting plate 2 and is connected to the rotating handle 10.

[0022] Limiting rings 12 are installed at both ends of the take-up roller 8. The limiting rings 12 are used to limit the lead curtain 4 and prevent the lead curtain 4 from displacing to a large extent along the length of the take-up roller 8.

[0023] A rectangular barrier 3 is provided at the bottom edge of the mounting plate 2. The rectangular barrier 3 is provided to block and hide the drive components and protective components, and improve the aesthetics. The take-up roller 8 connected to the rotating handle 10 moves through the rectangular barrier 3.

[0024] In this embodiment, the mobile DR head 1 is moved to a position directly above the lesion on the patient's body. It should be noted that the mobile DR head 1 is installed on the mobile host, which is a publicly available structural feature, and therefore it is not described in detail.

[0025] Before the inspection, the manual drive handle 10 is turned. The rotation of handle 10 drives the corresponding take-up roller 8 to rotate, thereby unwinding the lead curtain 4. With the coordinated transmission of three sets of gear components, the four take-up rollers 8 rotate synchronously to achieve synchronous unwinding of the lead curtain 4 around the perimeter until the bottom of the lead curtain 4 is close to the skin. This can provide closed protection around the mobile DR head 1, thereby accurately blocking the radiation generated by the mobile DR head 1 during subsequent operation, effectively improving the protection effect for medical staff and other patients in the ward. The lead curtain 4 is designed as a retractable structure, which greatly reduces the space occupied by the protective device, making the protective device more compact and concise.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, a mobile DR protection device is proposed. Compared with the first embodiment, in this embodiment, a rectangular counterweight frame 5 is provided below the mounting plate 2. The bottom ends of the four lead curtains 4 are respectively connected to the four sides of the rectangular counterweight frame 5. The rectangular counterweight frame 5 can pull the lead curtains 4 so that the lead curtains 4 are in a taut state, thereby reducing the gap between two adjacent lead curtains 4.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
