[0002] In medical procedures involving radiation, such as DR (radiofrequency ablation) examinations, radiation protection is crucial to ensure the safety of medical staff and patients. Traditional radiation shielding screens have several shortcomings. Firstly, their structure is mostly fixed, bulky, and non-foldable, occupying significant space when not in use. This makes storage in examination rooms and transportation extremely inconvenient, causing considerable challenges to space planning and equipment management in medical institutions. Secondly, traditional screens are made of lead, making them heavy and having a high center of gravity, and they do not provide adequate stable support, easily wobbling or even tipping over during placement. Furthermore, moving traditional screens usually requires multiple people, which is labor-intensive and inefficient, failing to meet the fast-paced and efficient work rhythm of modern medicine. Therefore, the development of a new type of radiation shielding screen is essential. Utility Model Content

The various drawings only schematically illustrate the concept and principle of the embodiments of this disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of this disclosure. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0023] Example 1: The foldable lead protective screen for DR examination in this example includes a protective screen assembly 1. Side screens 2 are hinged to the left and right side walls of the protective screen assembly 1. Electrically controlled support legs 3 are fixedly connected to the lower front and rear side walls of the side screens 2. The protective screen assembly 1 includes a main screen 1-1. Eight hinges 1-2 are fixedly connected to the left and right sides of the main screen 1-1 for connecting the side screens 2. An observation window 1-3 is embedded and fixedly fixed inside the upper part of the main screen 1-1. Connecting blocks 1-4 are fixedly connected to the left and right sides of the rear side walls of the main screen 1-1 and the side screens 2. The top ends of the universal rollers 1-5 are fixed to the bottom surface of the connecting blocks 1-4. The electrically controlled support legs 3 include a fixing block 3-1. The side wall of the fixing block 3-1 away from the upper push rod 3-5 and the pull arm 3-2 is fixedly connected to the front and rear side walls of the main screen 1-1 and the side screen 2, respectively. An upper electric actuator 3-5 is hinged to the upper end of the fixed block 3-1, and a traction arm 3-2 is hinged to the lower end of the fixed block 3-1. The inner and outer ends of the traction arm 3-2 are respectively hinged to the lower end of the fixed block 3-1 and the inner end of the triangular block 3-4 via pins. The telescopic end of the upper electric actuator 3-5 is hinged to the upper surface of the traction arm 3-2. Both the inner and outer ends of the upper electric actuator 3-5 are hinged to the upper end of the fixed block 3-1 and the upper surface of the traction arm 3-2 via pins, which are used to control the rotation of the traction arm 3-2 along the hinge point with the fixed block 3-1. A lower electric push rod 3-3 is hinged to the lower surface of the traction arm 3-2. Both ends of the lower electric push rod 3-3 are hinged to the bottom surface of the traction arm 3-2 and the inner sidewall of the support leg 3-6 via pins, controlling the rotation of the support leg 3-6 along the hinge point of the triangular block 3-4. A triangular block 3-4 is hinged to the end of the traction arm 3-2, and the other side of the triangular block 3-4 is fixedly connected to the support leg 3-6. The end of the support leg 3-6 is hinged to the top end of the silicone support plate 3-7 via a pin. The electrically controlled support leg 3 is arranged in a mirror-symmetrical configuration with the central axis of the main screen 1-1 as the reference line. When in use, to extend the screen for protection, the upper electric push rod 3-5 of the electrically controlled support leg 3 extends, pushing the pull arm 3-2 to rotate around the hinge point with the fixed block 3-1, causing the pull arm 3-2 to tilt downwards. Simultaneously, the lower electric push rod 3-3 extends, pushing the support leg 3-6 to rotate around the hinge point with the triangular block 3-4, causing the support leg 3-6 to unfold. The silicone support plate 3-7 contacts the ground, providing support. At the same time, the side screen 2 unfolds around the hinge 1-2, forming a protective area together with the main screen 1-1. To fold the screen, the upper electric push rod 3-5 and the lower electric push rod 3-3 shorten, retracting the pull arm 3-2 and the support leg 3-6. Then, the side screen 2 is folded around the hinge 1-2 to both sides of the main screen 1-1.

[0024] Example 2: The foldable lead protective screen for DR inspection in this example has a similar overall structure to Example 1, including a protective screen assembly 1, a side screen 2, and an electrically controlled support leg 3. The protective screen assembly 1 has a main screen 1-1, a hinge 1-2, and an observation window 1-3. The main screen 1-1 and the side screen 2 are connected by the hinge 1-2, and a universal roller 1-5 is installed on the rear side via a connecting block 1-4. The fixing block 3-1 of the electrically controlled support leg 3 is fixedly connected to the front and rear side walls of the main screen 1-1 and the side screen 2. The upper electric push rod 3-5 and the pulling arm 3-2 are respectively hinged to the upper and lower ends of the fixing block 3-1. The connection method between the pulling arm 3-2 and the upper electric push rod 3-5, the lower electric push rod 3-3, the triangular block 3-4, etc., is the same as in Example 1. The end of the support leg 3-6 is hinged to a silicone support plate 3-7. The difference is that the electrically controlled support leg 3 is arranged in a mirror-symmetrical manner with the central axis of the main screen 1-1 as the reference line. During operation, when unfolding the screen, activate the electrically controlled support leg 3. The upper electric push rod 3-5 extends, causing the pull arm 3-2 to rotate, and the lower electric push rod 3-3 extends, causing the support leg 3-6 to unfold. The silicone support plate 3-7 then touches the ground for support, and the side screen 2 unfolds. When folding, the upper electric push rod 3-5 and the lower electric push rod 3-3 shorten, retracting the pull arm 3-2 and the support leg 3-6, and then folding the side screen 2 to both sides of the main screen 1-1.

[0025] Example 3: The foldable lead protective screen for DR inspection in this example also includes a protective screen assembly 1, a side screen 2, and electrically controlled support legs 3. The protective screen assembly 1 consists of a main screen 1-1, eight hinges 1-2, and an observation window 1-3. The main screen 1-1 and the side screen 2 are connected by hinges 1-2, and universal casters 1-5 are installed on the rear side via connecting blocks 1-4. The fixing block 3-1 of the electrically controlled support leg 3 is fixed to the front and rear side walls of the main screen 1-1 and the side screen 2. The upper electric push rod 3-5 is hinged to the upper end of the fixing block 3-1, and the traction arm 3-2 is hinged to the lower end of the fixing block 3-1. The connection methods between the upper electric push rod 3-5 and the traction arm 3-2, the lower electric push rod 3-3 and the traction arm 3-2 and the support leg 3-6, and the support leg 3-6 and the silicone support plate 3-7 are all consistent with the previous examples. The electrically controlled support legs 3 are arranged in a mirror-symmetrical manner with the central axis of the main screen 1-1 as the reference line. When the screen position needs to be adjusted, the universal casters 1-5 can be used to move the screen. When unfolding the screen protection, first control the electric support leg 3 to extend the upper electric push rod 3-5, causing the pull arm 3-2 to rotate, and the lower electric push rod 3-3 to extend the support leg 3-6, so that the silicone support plate 3-7 contacts the ground for stable support. Then unfold the side screen 2. When folding, reverse the operation of the electric push rod of the electric support leg 3 to retract the relevant parts, and then fold the side screen 2 to both sides of the main screen 1-1.

[0026] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0027] In its initial state, the main screen 1-1 of the protective screen assembly 1 is upright, the side screens 2 are folded to both sides of the main screen 1-1 via hinges 1-2, and the electrically controlled support legs 3 are retracted. At this time, the overall space occupied by the screen is small, making it easy to store and move. When DR inspection protection is required, the electrically controlled support legs 3 are first unfolded, and the upper push rod 3-5 in the electrically controlled support leg 3 starts to work, extending its telescopic end. Since both the inner and outer ends of the upper push rod 3-5 are hinged to the upper end of the fixed block 3-1 and the upper surface of the pull arm 3-2 via pins, the extension of the upper push rod 3-5 will push the pull arm 3-2 to rotate along the hinge point with the fixed block 3-1, causing the pull arm 3-2 to tilt downward. Next, the lower push rod 3-3 starts to work. Both ends of the lower push rod 3-3 are hinged to the bottom surface of the pull arm 3-2 and the inner side wall of the support leg 3-6 through the shaft pin. When the lower push rod 3-3 extends, it pushes the support leg 3-6 to rotate along the hinge point of the triangular block 3-4, so that the support leg 3-6 gradually unfolds. The silicone support plate 3-7 at the end of the support leg 3-6 contacts the ground and plays a role in stabilizing support. At this time, the electrically controlled support leg 3 completes the unfolding action and provides stable support for the screen. The electrically controlled support leg 3 can be installed in a front-to-back mirror symmetrical arrangement or a left-to-right mirror symmetrical arrangement with the central axis of the main screen 1-1 as the reference line, which can achieve stable support.

[0028] Then, the side screens 2, folded on both sides of the main screen 1-1, are unfolded around hinges 1-2, so that the side screens 2 and the main screen 1-1 are on the same plane, forming a protective area together. A fixed observation window 1-3 is embedded in the upper part of the main screen 1-1 for medical personnel to observe the examination. When moving the screen, since the left and right sides of the rear sidewalls of the main screen 1-1 and side screens 2 are fixedly connected to universal casters 1-5 via connecting blocks 1-4, the screen can be pushed, and the movement of the screen is achieved by the rolling of the universal casters 1-5. When the DR examination is completed and the protective screen is no longer needed, first, the electrically controlled support leg 3 is retracted, the lower electric push rod 3-3 is shortened, and the support leg 3-6 is pulled to rotate around the hinge point of the triangular block 3-4, causing the support leg 3-6 to retract. Then, the upper electric push rod 3-5 is shortened, and the pulling arm 3-2 is pulled to rotate around the hinge point with the fixed block 3-1, causing the pulling arm 3-2 to return to its initial position, and the electrically controlled support leg 3 is retracted. Fold the side screen 2 around the hinge 1-2 to both sides of the main screen 1-1, so that the screen returns to its initial folded state for easy storage and future use.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
