Description

Technical Field

[0001] This invention relates to the field of medical radiation protection equipment technology, specifically to a portable radiation protection device with a multi-layered isolation and protection structure. Background Technology

[0002] Some medical procedures involve the use of equipment that emits radiation. For patients, this is a single exposure, and the radiation dose can be controlled within acceptable limits. However, for medical staff, this involves long-term exposure, which inevitably causes irreversible damage to their health. Current radiation protection methods mostly rely on wearable devices. Traditional wearable radiation protection devices contain heavy metals such as lead plates, making them heavy and inconvenient for doctors to perform medical procedures. To address this, a mobile radiation protection device has been designed, which uses a movable protective panel to shield and protect doctors. However, the protective panel structure of such mobile protective devices is mostly designed for the highest level of protection, resulting in bulky panels and compatibility issues with different radiation sources. Therefore, improvements to this type of mobile protective device are needed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a portable radiation protection device with a multi-layered isolation and protection structure. Based on the different optimal protective materials for different radiation sources and the varying thicknesses of the protective structure for different doses of radiation sources, this invention employs a structure with both storage and mobility characteristics. This allows for the prefabrication of single protective panels, the use of specific protective panels depending on the radiation source requiring protection, and the insertion of different numbers of protective panels according to the protection level. This results in a radiation protection device that can adaptively adjust its protective structure and move with the user.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] It includes a base and a rack, wherein the rack is fixedly mounted on the base, and it also includes:

[0006] A movable component, wherein the movable component is mounted on a rack;

[0007] The support components are two in number, one of which is mounted on the movable component and the other is mounted on the base.

[0008] Side frame, which is stacked within the load-bearing component;

[0009] A protective insert plate, wherein the protective insert plate is embedded and fixed inside the side frame;

[0010] When in use, the device is placed between the user and the radiation source. A certain number of protective inserts are placed inside the support component. The support component on the moving component then moves the protective inserts inside to shield and protect the user. Depending on the level of protection, the protective inserts inside the support component on the base are moved out and placed into the support component on the moving component, or the protective inserts inside the support component on the moving component are placed into the support component on the base for storage.

[0011] Preferably, the moving component comprises:

[0012] The platform is mounted inside the frame;

[0013] The support shaft consists of two shafts, which are fixedly mounted at both ends of the base. The support shafts are spun through the side plates of the frame via bearings.

[0014] A support slide rail is fixedly mounted on the base.

[0015] A stepper seat, wherein the stepper seat is mounted on a support slide rail and an electric stepping system is provided on the stepper seat;

[0016] A flip motor is fixedly mounted on the frame, and the output shaft of the flip motor is connected to a support shaft on one side for transmission.

[0017] In use, the rotating motor drives the support shaft to rotate, which in turn drives the base to rotate. The base then drives the support slide rail to rotate. When the support slide rail rotates the load-bearing component on it to the lower position, the stepper seat drives the load-bearing component on it to dock with the load-bearing component on the base, realizing the interactive movement of the protective inserts in the two load-bearing components. When the support slide rail rotates the load-bearing component on it to the upper position, the load-bearing component on the support slide rail, together with the protective inserts inside, provides radiation protection for the user.

[0018] Preferably, the carrier component comprises:

[0019] The carrier box is fixedly mounted on the stepper seat in one set of carrier components, and the carrier box in the other set of carrier components is fixedly mounted on the base.

[0020] An insertion port is provided on one side wall of the carrier box, and the side frames are stacked and placed inside the carrier box;

[0021] A limiting mechanism is provided inside the carrier box, and the side frame abuts against the inner wall of the carrier box through the limiting mechanism;

[0022] The guide groove is provided in pairs, with the two guide grooves in each pair fixedly installed on the upper and lower inner walls of the carrier box, and the guide groove is located at one end of the insertion port.

[0023] The pusher plate is set inside the carrier box, and the upper and lower ends of the pusher plate are respectively movably set in the guide grooves on the upper and lower sides.

[0024] A drive mechanism is mounted on the carrier box and is connected to the pusher plate via a transmission mechanism.

[0025] In use, for different radiation sources, corresponding protective plates are installed in the side frames. The protective plates are then placed in the carrier box by stacking the side frames. The stacked side frames are pressed together by a limiting mechanism to prevent them from moving around in the carrier box. The pusher plate is driven by a drive mechanism to move, and then the pusher plate pushes the side frame located on one side of the guide groove in the carrier box to move out of the carrier box, realizing the interactive movement of the protective plates in the two carrier boxes.

[0026] Preferably, the limiting mechanism comprises:

[0027] The limiting frame is installed inside the carrier box and abuts against the side frame on the side away from the insertion port;

[0028] A support spring is provided, with one end fixedly mounted on the limit frame and the other end fixedly mounted on the inner wall of the bearing box.

[0029] The limiting block is fixedly installed on the inner wall of the bearing box, and the limiting block is located on the side opposite to the side frame of the limiting frame.

[0030] An elastic pad is fixedly installed on one side wall of the limiting frame facing the side frame;

[0031] In use, at least one side frame is placed inside the carrier box, and then the limiting frame is held against by the support spring. The limiting frame holds against the side frame by the elastic pad, thus pressing the side frame against the inner wall of the carrier box located on one side of the guide groove.

[0032] Preferably, the drive mechanism comprises:

[0033] The mounting slot is inserted and fixed on the plate on the side of the carrier box away from the socket.

[0034] The push rod is screwed into the mounting groove via a rotating shaft, and the push rod extends into the bearing box;

[0035] A connecting seat, wherein the connecting seat is spun onto the movable end of the push rod via a rotating shaft;

[0036] A connecting slide rail is fixedly mounted on the pusher plate, and a connecting seat is slidably mounted on the connecting slide rail;

[0037] The handle is screwed into the mounting groove via a rotating shaft, and the rotating shaft of the handle and the rotating shaft of the push rod are connected by a gear set for transmission.

[0038] A reset spring, one end of which is fixedly mounted on the handle, and the other end of which is fixedly mounted on the outer wall of the bearing box;

[0039] In use, pulling the handle rotates the gear set, which in turn drives the push rod to rotate. The push rod pushes the connecting seat, which then slides on the connecting slide rail and pushes the pusher plate to slide in the guide groove. The pusher plate then pushes the side frame out of the carrier box. After releasing the handle, the reset spring drives the handle to reset, which in turn drives the push rod to reset. The push rod is locked on the connecting slide rail by the connecting seat, which in turn drives the pusher plate to reset. At this time, the support spring pushes the limit frame, which pushes one of the rear side frames to the side of the pusher plate and presses it against the inner wall of the carrier box.

[0040] Preferably, a limiting seat is fixedly provided on the base, and the limiting seat is located below the insertion port side of the carrier box on the base.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. This device is equipped with two carrier boxes. The carrier box located on the support slide rail contains protective inserts to provide radiation protection for the user. The carrier box located on the base contains and stores excess protective inserts. This allows the number of protective inserts in the carrier box on the support slide rail to be adjusted according to the change in protection level requirements.

[0043] 2. This device uses a pedestal to mount the support slide rail on the frame, thereby enabling the support slide rail to rotate freely. A carrier box is mounted on the support slide rail via a stepper seat, thereby enabling the carrier box to move and allowing a protective insert plate to be inserted inside the carrier box. The stepper seat drives the carrier box to move with the user, thus achieving radiation protection for the user. Attached Figure Description

[0085] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0086] When using this device, depending on the protection against different radiation sources, a protective insert 6 is selected and embedded into the side frame 5 to form a prefabricated component. The protective insert 6 is then inserted into the carrier box 4-1 and stacked.
