Description

Technical Field

[0001] This utility model relates to the field of nuclear medicine technology, specifically to an integrated radiation shield for nuclear medicine nursing equipment. Background Technology

[0002] Nuclear medicine is mainly based on the decay properties of radioactive nuclides. Radioactive nuclides spontaneously emit radiation and transform into another nuclide. This process is called radioactive decay. Different types of radiation have different penetrating and ionizing abilities. These properties can be used for the diagnosis and treatment of diseases.

[0003] Chinese utility model patent CN221285762U discloses a radiation shield for radiology departments, comprising a telescopic column, a rotating platform, a base, casters, a connecting seat, a limiter, a support plate, a baffle, a shock absorber, and a rotating shaft. The telescopic column has a rotating platform at its bottom end, and the rotating platform has a base at its bottom end, with casters mounted on the bottom surface of the base. One end of the limiter is connected to the top of the telescopic column via the connecting seat. The limiter, baffle, and shock absorber of this utility model ensure that the bottom surface of the baffle contacts the ground during use, effectively eliminating gaps between the baffle and the ground, thus providing better shielding and enhancing safety. It also offers high flexibility, does not obstruct the view, prevents noise upon contact with the ground, and provides good cushioning, facilitating market promotion and application.

[0004] The aforementioned radiation shields offer high flexibility during use, do not obstruct the line of sight, and prevent noise when in contact with the ground, providing excellent cushioning and facilitating market promotion and application. However, because the shields are located in front of medical personnel, they completely block their view, making it difficult for them to operate the instruments in front of them. When operating the instruments, their hands need to be exposed to the radiation zone, which not only exposes their hands to direct radiation risk but may also cause potential harm to their health in the long run. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated radiation shield for nuclear medicine nursing equipment, which has advantages such as improved protection and ease of operation for medical personnel, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated radiation shield for nuclear medicine nursing equipment, comprising a main shield and two auxiliary shields, each of the auxiliary shields being hinged to both sides of the main shield, the main shield extending along both sides in the width direction, and casters installed at the bottom of both the main shield and the auxiliary shields;

[0007] An operating port is provided in the central area of ​​the main baffle. A lead plate is provided in front of the main baffle. A rectangular slide rod is slidably inserted into the front of the main baffle. Two fixing blocks are fixedly connected to the side of the main baffle corresponding to the lead plate. Both fixing blocks are rotatably connected to the outer circumference of the slide rod.

[0008] The outer circumferential surface of the slide bar is provided with a fixing component to limit the angle of the lead plate;

[0009] A locking component is provided on the side of the main baffle that is away from the lead plate.

[0010] Furthermore, the fixing component includes two fixing blocks that are fixedly connected to a ratchet on one side. A T-shaped sliding member is slidably inserted into the outer circumferential surface of the slide rod located between the main baffle and the lead plate. A spring is fixedly connected between the sliding member and the slide rod. Both bottom ends of the sliding member along its length are fixedly connected to a locking block, and both locking blocks are adapted to the corresponding ratchet.

[0011] With the above solution, through the cooperation of the ratchet and the locking block, under the action of the spring force, the sliding part can drive the locking block to engage in the tooth groove of the ratchet, thereby fixing the angle of the lead plate. When it is necessary to adjust the angle of the lead plate, simply overcome the spring force and slide the sliding part to make the locking block disengage from the ratchet tooth groove, and the lead plate can be rotated to the required angle. The operation is convenient and can stably maintain the adjusted angle of the lead plate.

[0012] Furthermore, the locking assembly includes two threaded rings that are rotatably connected to the main baffle and the lead plate on opposite sides. The outer circumferential surface of the slide rod along both sides of the length direction is provided with threaded grooves, and each threaded ring is adapted to the corresponding threaded groove.

[0013] With the above solution, when it is necessary to fix the position of the slide rod, slide the slide rod so that the threaded groove contacts the threaded ring, and rotate the threaded ring to make it threadedly connected with the threaded groove on the slide rod, thereby locking the slide rod on the main baffle and preventing the slide rod from accidentally sliding and causing the lead plate to change position, affecting the protective effect and operation; when it is necessary to adjust the position or angle of the lead plate, rotate the threaded ring in the opposite direction to make it disengage from the threaded groove, which can release the lock on the slide rod and facilitate related operations.

[0014] Furthermore, two support pillars are fixedly connected to the side of the main baffle that is opposite to the lead plate, and omnidirectional wheels are installed at the bottom of the two support pillars.

[0015] The above-mentioned scheme, with the cooperation of the two casters and the support column, can support the main baffle, prevent the main baffle from tipping over due to instability of the center of gravity or external impact, and ensure the safety of the equipment during use.

[0016] Furthermore, handrails are fixedly connected to the inclined surfaces of both sub-baffles, and lead glass is installed on the front of the main baffle.

[0017] With the above solution, the handrails make it easier for staff to push or pull the secondary baffle, thereby adjusting the layout and protection range of the entire radiation shield. The operation is more labor-saving and convenient. When medical personnel leave the radiation area, they can face away from the main baffle and pull the two handrails to stay under the continuous radiation protection of the baffle, and leave the radiation area safely and orderly.

[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0019] This integrated radiation shield for nuclear medicine nursing equipment features a lead plate that extends outwards under the push of a sliding rod, allowing medical personnel to operate the equipment through an access port. The lead plate protects the medical personnel's hands from radiation exposure. Furthermore, a fixed block rotatably connects to the sliding rod, allowing for angle adjustment of the lead plate. This ensures that the hands remain within the effective protection range of the lead plate during operation, while also avoiding potential issues of obstructed vision and limited operating space when the lead plate is parallel to the main shield, thus improving operational convenience and safety.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figures 1-4 This embodiment describes an integrated radiation shield for a nuclear medicine nursing device, comprising a main shield 1 and two auxiliary shields 2. Each auxiliary shield 2 is hinged to both sides of the main shield 1. The main shield 1 extends along both sides in the width direction. Both the main shield 1 and the auxiliary shield 2 are equipped with casters at their bottom ends. The combination of the two auxiliary shields 2 and the main shield 1 increases the radiation shielding area, thereby improving the radiation protection effect. The extended sides of the main shield 1 prevent radiation from entering through the hinge gap between the main shield 1 and the auxiliary shield 2, further enhancing the radiation protection effect.

[0032] An operating port 3 is provided in the central area of ​​the main baffle 1. A lead plate 4 is provided in front of the main baffle 1. A rectangular slide rod 5 is slidably inserted into the front of the main baffle 1. Two fixing blocks 6 are fixedly connected to the side of the lead plate 4 corresponding to the main baffle 1. Both fixing blocks 6 are rotatably connected to the outer circumference of the slide rod 5. The operating port 3 allows the staff to operate the equipment in front of the baffle. The lead plate 4 provides protection in front of the operating port 3, protecting the staff's exposed radiation area. At the same time, the rotatable connection between the fixing blocks 6 and the slide rod 5 allows the angle of the lead plate 4 to be adjusted, preventing the lead plate 4 from being parallel to the main baffle 1 and affecting the staff's operation of the equipment.

[0033] A fixing component 7 is provided on the outer circumference of the slide bar 5 to limit the angle of the lead plate 4.

[0034] A locking component 8 is provided on the side of the main baffle 1 that is away from the lead plate 4.

[0035] The fixing component 7 includes two fixing blocks 6, each fixedly connected to a ratchet 701 on one side. A T-shaped sliding member 702 is slidably inserted into the outer circumference of the slide rod 5 located between the main baffle 1 and the lead plate 4. A spring 703 is fixedly connected between the sliding member 702 and the slide rod 5. Both bottom ends of the sliding member 702 along its length are fixedly connected to locking blocks 704. Both locking blocks 704 are adapted to the corresponding ratchet 701. Through the cooperation of the ratchet 701 and the locking blocks 704, under the elastic force of the spring 703, the sliding member 702 can drive the locking blocks 704 to engage in the tooth groove of the ratchet 701, thereby fixing the angle of the lead plate 4. When it is necessary to adjust the angle of the lead plate 4, simply overcome the elastic force of the spring 703 and slide the sliding member 702 to disengage the locking blocks 704 from the tooth groove of the ratchet 701, and the lead plate 4 can be rotated to the required angle. The operation is convenient and can stably maintain the adjusted angle of the lead plate 4.

[0036] The locking assembly 8 includes two threaded rings 801 that are rotatably connected to the main baffle 1 and the lead plate 4 on opposite sides. The outer circumferential surface of the slide rod 5 along its length is provided with threaded grooves 802 on both sides. Each threaded ring 801 is adapted to the corresponding threaded groove 802. When it is necessary to fix the position of the slide rod 5, slide the slide rod 5 so that the threaded groove 802 contacts the threaded ring 801, and rotate the threaded ring 801 to make it threadedly connected to the threaded groove 802 on the slide rod 5, thereby locking the slide rod 5 onto the main baffle 1. This prevents the slide rod 5 from accidentally sliding and causing the lead plate 4 to change position, affecting the protective effect and operation. When it is necessary to adjust the position or angle of the lead plate 4, rotate the threaded ring 801 in the opposite direction to disengage it from the threaded groove 802, thereby releasing the lock on the slide rod 5 and facilitating related operations.

[0037] Two support columns 9 are fixedly connected to the side of the main baffle 1 that is opposite to the lead plate 4. The bottom of each support column 9 is equipped with casters. The casters and support columns 9 work together to support the main baffle 1 and prevent it from tipping over due to instability or external impact, thus ensuring the safety of the equipment during use. Handrails 10 are fixedly connected to the inclined surfaces of the two auxiliary baffles 2. Lead glass 11 is installed on the front of the main baffle 1. The handrails 10 make it easy for staff to push or pull the auxiliary baffles 2 to adjust the layout and protection range of the entire radiation shield. The operation is more labor-saving and convenient. When medical personnel leave the radiation area, they can turn away from the main baffle 1 and pull the two handrails 10 to stay under the continuous radiation protection of the baffle and leave the radiation area safely and orderly.

[0038] The working principle of the above embodiment is as follows: First, when medical personnel operate equipment that requires access to the outside world, they rotate the two threaded rings 801 in the opposite direction, causing the two threaded rings 801 to push the threaded grooves 802, causing the slide rods 5 to slide out. The two slide rods 5 will push the lead plate 4 away from the main baffle 1. Subsequently, the staff can operate the equipment through the operating port 3, or they can slide the sliding member 702 upward to separate the locking block 704 from the ratchet 701, thereby unlocking the lead plate 4. The staff can push the upper or lower end of the lead plate 4 through the operating port 3 to adjust the angle of the lead plate 4, preventing the lead plate 4 from being parallel to the main baffle 1 and affecting the staff's operation of the equipment. After the adjustment is completed, the sliding member 702 is reset under the action of the spring 703, causing the locking block 704 to re-contact the ratchet 701, locking the adjusted lead plate 4 and keeping the lead plate 4 in a stable state. This allows the staff to operate the equipment under the protection of the lead plate 4, which not only improves the radiation protection capability but also facilitates the operation of medical personnel.
