Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and specifically to a convenient medical isolation screen. Background Technology
[0002] In the clinical diagnosis and treatment of nuclear medicine, bedside injection is one of the common procedures. Medical staff need to inject patients with high-energy radioactive nuclide drugs. The radiation released by these drugs can cause radiation damage to medical staff. Long-term exposure can easily lead to occupational health risks. Therefore, protective equipment is an indispensable device in bedside injection procedures in nuclear medicine.
[0003] Currently, most existing medical isolation screens are fixed structures, which cannot be flexibly moved to the bedside of patients with limited mobility for close-range operation. Medical staff or patients need to adjust the body position adaptation device, resulting in extremely poor operational flexibility. Although some movable isolation screens are equipped with wheels, they lack automatic positioning functions and are prone to sliding after being moved. In addition, the protective module and the lifting structure are set up independently, requiring medical staff to adjust the height of each component separately, which can easily lead to misalignment between the protective and operating heights, resulting in loopholes in radiation protection.
[0004] Meanwhile, the existing protective structure of isolation screens has obvious defects: most of them only use a single lead glass or simple lead apron for protection, which cannot achieve 360-degree protection without blind spots. In particular, the area around the operation hole of the lead apron sleeve is prone to radiation blind zone, and rays can easily penetrate through the gaps; some foldable lead aprons have poor sealing performance at the folds, which can easily create gaps and further reduce the protective effect.
[0005] Furthermore, existing isolation screens lack ease of operation; some protective components require manual adjustment and resetting by medical staff, increasing their physical exertion and increasing the risk of inadequate protection due to oversights. In summary, existing medical isolation screens suffer from numerous problems, including inconvenience in movement, incomplete protection, and cumbersome operation, failing to fully meet the actual protection needs and ease of operation requirements of bedside injection scenarios in nuclear medicine departments.
[0006] In summary, the present invention provides a convenient medical isolation screen to solve the above problems. Summary of the Invention
[0007] To address the aforementioned issues, this invention provides a convenient medical isolation screen for bedside injection scenarios in nuclear medicine departments. It provides comprehensive radiation protection for medical personnel while enhancing the device's mobility and ease of operation. It adapts to the operational needs of medical personnel of different heights and patients in different positions, reducing the radiation dose and physical exertion of medical personnel. This overcomes the technical shortcomings of existing isolation screens, such as insufficient protection and cumbersome operation.
[0008] To achieve the above objectives, the technical solution of the present invention is as follows: a convenient medical isolation screen, comprising a main frame, on which are installed a movable support module for enabling flexible movement and stable positioning of the device, a protective module for providing 360-degree radiation protection for medical personnel and ensuring visual operation, and a lifting linkage module for driving the protective module to rise and fall to adapt to different operating heights. The movable support module is installed at the bottom of the main frame, and the lifting linkage module is located in the middle of the main frame.
[0009] The protective module includes a lead glass protective screen, a wraparound lead apron, and operating holes for the lead apron sleeves. The lead glass protective screen is fixedly connected to the bottom of the main frame. The lead glass protective screen is used to enable visual injection operations. The operating holes for the lead apron sleeves are symmetrically opened on both sides of the main frame below the lead glass protective screen. The wraparound lead apron is used to achieve 360-degree protection without blind spots. The wraparound lead apron is wrapped around the operating side of the main frame.
[0010] The lifting linkage module is connected to a control module, which controls the lifting linkage module and thus simultaneously drives the lead glass protective screen and the enclosed lead apron to rise and fall synchronously.
[0011] Furthermore, a functional integration module is also installed on the main frame. The functional integration module includes an external waste lead container and a medical communication speaker. The external waste lead container is used to collect radioactive waste after injection, and the medical communication speaker is used to solve the problem of inconvenient communication between medical staff and patients after the protective module is blocked. The functional integration module also includes a placement component, which is used to place single-use radiopharmaceutical containers.
[0012] Furthermore, the movable support module includes a universal pulley with a self-locking structure. The universal pulley is detachably connected to the bottom of the main frame, and the control module is signal-connected to the self-locking structure of the universal pulley. When the lifting linkage module is adjusted to the preset height threshold, the control module synchronously triggers the self-locking of the universal pulley.
[0013] Furthermore, the lifting linkage module includes a transmission component, a linkage bracket, and a drive component. The transmission component is embedded inside the main frame. The linkage bracket is fixedly connected to the lead glass protective screen and the enclosed lead apron respectively. The drive component is poweredly connected to the transmission component. The control module is signal-connected to the drive component. The control module is used to control the drive component to drive the transmission component to move, thereby driving the lead glass protective screen and the enclosed lead apron to lift synchronously through the linkage bracket.
[0014] The transmission component includes a gear, which is coaxially and fixedly connected to the output shaft of the drive component. The gear meshes with a rack, which is vertically set along the height direction of the main frame. The end of the rack away from the gear is fixedly connected to the linkage bracket. The linkage bracket has a "U" shaped structure. The top of the linkage bracket is fixedly connected to the bottom of the lead glass protective screen, and the two sides of the linkage bracket are fixedly connected to the back of the enclosed lead apron.
[0015] Furthermore, a liftable injection stage is also provided in the middle of the main frame. The injection stage is fixedly connected to the linkage bracket and rises and falls synchronously with the lifting linkage module.
[0016] Furthermore, the enclosed lead apron includes several foldable lead plates, all of which are connected by an overlapping sealing structure, and elastic lead pads are embedded at the overlaps. The elastic lead pads are fixedly connected to the foldable lead plates on both sides. The folding nodes of the foldable lead plates are hinged with connecting rods, and the end of the connecting rod away from the foldable lead plate is hinged to the bottom of the lead glass protective screen. When the lead glass protective screen is raised and lowered with the lifting linkage module, the connecting rods synchronously drive the foldable lead plates to extend, retract, and fold.
[0017] Furthermore, the placement assembly includes a lead placement base, a limiting clamp, and a protective cover. The lead placement base has an arc-shaped groove inside that matches the single-unit radiopharmaceutical canister. The inner wall of the arc-shaped groove is provided with a buffer anti-slip pad. The limiting clamp is hinged to the top of the lead placement base and is used to clamp and fix the single-unit radiopharmaceutical canister. The protective cover is hinged to the lead placement base, and an electromagnetic lock is installed between the protective cover and the lead placement base.
[0018] A pressure sensor is installed inside the operating hole of the lead apron sleeve. Both the pressure sensor and the electromagnetic lock are connected to the control module. When a medical staff member inserts their arm into the operating hole and presses the pressure sensor, the control module controls the electromagnetic lock to unlock and simultaneously triggers the protective cover to open automatically.
[0019] Furthermore, the doctor-patient communication loudspeaker includes several radio amplification units, which are respectively installed on both sides of the lead glass protective screen. The doctor-patient communication loudspeaker is connected to the control module. When the control module determines that the pressure sensor detects that a medical staff member's arm has entered the operating hole, the control module automatically starts the doctor-patient communication loudspeaker. When the arm is withdrawn from the operating hole, the doctor-patient communication loudspeaker automatically turns off.
[0020] Furthermore, the lead apron sleeve operating hole is also circumferentially equipped with several rotatable lead baffles. The lead baffles are hinged to the side wall of the lead apron sleeve operating hole, and a torsion spring is provided at the hinge point between the lead baffles and the lead apron sleeve operating hole. The torsion spring is used for the automatic reset of the lead baffles. When the medical staff's arm is inserted into the lead apron sleeve operating hole, it causes the lead baffles to rotate, thereby blocking the radiation blind zone around the lead apron sleeve operating hole. When the medical staff's arm is pulled out of the lead apron sleeve operating hole, the lead baffles automatically reset.
[0021] Furthermore, a sealing cap is provided at the opening of the external waste lead container, one side of which is hinged to the opening of the external waste lead container, and a return spring is provided at the hinge between the sealing cap and the opening.
[0022] The above approach has the following beneficial effects:
[0023] 1. This solution achieves coordinated linkage between the protective module, the lifting linkage module, and the movable support module. The lifting linkage module can synchronously drive the lead glass protective screen and the enclosed lead apron to rise and fall. When the height reaches a preset threshold, the universal pulleys can be automatically locked. Compared with the traditional technology where the medical isolation screen protective components and lifting structure are set independently and require manual positioning after movement, this solution not only greatly simplifies the operation steps of medical staff and avoids the problems of misalignment between protection and operation height and sliding after the device is moved, but also significantly improves the stability of the device during operation. At the same time, the enclosed lead apron replaces the traditional heavy lead apron wearing mode, effectively reducing the physical exertion of medical staff.
[0024] 2. This solution optimizes the structural design of the enclosed lead apron, using foldable lead plates overlapped with elastic lead pads for sealing. The foldable lead plates extend and retract in conjunction with the lead glass protective screen via connecting rods. Compared with traditional fixed protective lead aprons or lead apron structures that easily leave gaps after folding, this solution achieves 360-degree protection without blind spots, effectively fills radiation gaps at the folds, prevents penetration by high-energy radioactive rays such as 18F, and improves protective safety. It can also adapt to different lifting height operation requirements, and the folding process reduces the storage space of the device, making it suitable for flexible use scenarios such as bedside injection.
[0025] 3. This solution integrates a functional module and a height-adjustable injection station. The placement components of the functional module, the external lead waste container, the doctor-patient communication speaker, and the pressure sensor are linked. The injection station and the lifting linkage module rise and fall synchronously. Compared with traditional technologies where medical isolation screens have limited functions, lack a dedicated injection operation table, require additional auxiliary tools for drug placement and waste collection, and hinder doctor-patient communication, this solution achieves integrated coordination of drug placement, injection operation, waste collection, and doctor-patient communication. It reduces the contact time between medical staff and radioactive drugs and waste, improves operational convenience, and the lead injection station, together with various lead functional components, further enhances the radiation protection effect.
[0026] 4. This solution features a rotatable lead baffle circumferentially positioned around the operating port of the lead apron sleeve, which automatically resets with a torsion spring. This baffle also works in conjunction with a pressure sensor-triggered linkage function. Compared to traditional lead apron sleeve operating ports that lack blind-spot protection or require manual baffle adjustment, this solution automatically blocks radiation blind spots around the operating port when the arm is inserted and automatically resets after the arm is withdrawn, eliminating the need for additional intervention by medical personnel. This effectively fills the radiation protection gap around the operating port. Furthermore, the integrated functional module and the linkage design with the injection station form a comprehensive, end-to-end protection and operational coordination system. The overall structural design is ingenious and easily conceived by those not skilled in the art, demonstrating outstanding creativity and significantly improving the adaptability and practicality of bedside injection scenarios in nuclear medicine departments.

[0035] The following detailed description illustrates the specific implementation method:
[0036] Example 1:
[0037] As attached Figures 1 to 4 As shown: A convenient medical isolation screen includes a main frame 1, a door panel 101 on one side of the main frame 1, a movable support module 5 for flexible movement and stable positioning of the device, a protective module for providing 360-degree radiation protection for medical personnel and ensuring visual operation, and a lifting linkage module for driving the protective module to rise and fall to adapt to different operating heights. The movable support module 5 is installed at the bottom of the main frame 1, and the lifting linkage module is located in the middle of the main frame 1.
[0038] The protective module includes a lead glass protective screen 2, a wraparound lead apron 3, and lead apron sleeve operation holes 10. In this embodiment, the wraparound lead apron 3 is a foldable lead plate 301 structure. The lead glass protective screen 2 is fixedly connected to the bottom of the main frame 1. The lead glass protective screen 2 is used to realize visual injection operation. The lead apron sleeve operation holes 10 are symmetrically opened on both sides of the main frame 1 below the lead glass protective screen 2. The wraparound lead apron 3 is used to realize 360-degree protection without blind spots. The wraparound lead apron 3 wraps around the operating side of the main frame 1. The lifting linkage module is signal-connected to the control module. The control module is used to control the lifting linkage module, thereby driving the lead glass protective screen 2 and the wraparound lead apron 3 to rise and fall synchronously.
[0039] The movable support module 5 includes a universal pulley with a self-locking structure. The universal pulley is detachably connected to the bottom of the main frame 1. The control module is signal-connected to the self-locking structure of the universal pulley. When the lifting linkage module is adjusted to the preset height threshold, the control module synchronously triggers the self-locking of the universal pulley.
[0040] The lifting linkage module includes a transmission component, a linkage bracket, and a drive component 6. In this embodiment, the drive component 6 is a motor. The transmission component is embedded inside the main frame 1. The linkage bracket is fixedly connected to the lead glass protective screen 2 and the enclosed lead apron 3, respectively. The drive component 6 is poweredly connected to the transmission component, and the control module is signal-connected to the drive component 6. The control module is used to control the drive component 6 to drive the transmission component to move, thereby driving the lead glass protective screen 2 and the enclosed lead apron 3 to move synchronously through the linkage bracket. The transmission component includes a gear 7, which is coaxially fixedly connected to the output shaft of the drive component 6. The gear 7 meshes with a rack 8, which is vertically set along the height direction of the main frame 1. The end of the rack 8 away from the gear 7 is fixedly connected to the linkage bracket. The linkage bracket has a "U" shaped structure. The top of the linkage bracket is fixedly connected to the bottom of the lead glass protective screen 2, and the two sides of the linkage bracket are fixedly connected to the back of the enclosed lead apron 3, respectively.
[0041] The enclosed lead apron 3 includes several foldable lead plates 301. The foldable lead plates 301 are all connected by an overlapping sealing structure, and elastic lead pads are embedded at the overlapping points. The elastic lead pads are fixedly connected to the foldable lead plates 301 on both sides. The folding nodes of the foldable lead plates 301 are hinged with connecting rods. The end of the connecting rod away from the foldable lead plates 301 is hinged to the bottom of the lead glass protective screen 2. When the lead glass protective screen 2 is raised and lowered with the lifting linkage module, the connecting rods synchronously drive the foldable lead plates 301 to extend, retract and fold.
[0042] The specific implementation process is as follows: First, according to the needs of bedside injection scenarios in nuclear medicine (such as renal dynamic imaging and bone triphasic injection), medical staff push the main frame 1 and use the universal pulleys with self-locking structure at the bottom to quickly move the portable medical isolation screen of this invention to the side of the target examination bed. Since the main frame 1 adopts a lightweight design and is combined with the flexible steering of the universal pulleys, it can be easily pushed to a close position next to the bed of patients with limited mobility, without the need for multiple people to carry it, which greatly improves the flexibility of operation.
[0043] Once in position, medical staff activate the lifting linkage module via the control module. The control module sends a control signal to the drive component 6 (motor). Upon activation, the drive component 6 rotates the gear 7, which is coaxially fixed to its output shaft. Since gear 7 meshes with a rack 8 vertically positioned along the height of the main frame 1, the rotation of gear 7 drives the rack 8 to move linearly in the vertical direction, thereby synchronously raising and lowering the "U"-shaped linkage bracket fixedly connected to the rack 8. During the raising and lowering of the linkage bracket, the lead glass protective screen 2 and the enclosed lead apron 3 are simultaneously raised and lowered. This solves the problems of existing devices where the protective components are cumbersome to match with the operating height and prone to misalignment. It also ensures that the lead glass protective screen 2 always corresponds to the operating area, does not obstruct the medical staff's visual field, and guarantees injection accuracy.
[0044] During the synchronous raising and lowering of the lead glass protective screen 2 and the enclosed lead apron 3, the foldable lead plate 301 of the enclosed lead apron 3 is hinged to the bottom of the lead glass protective screen 2 via a connecting rod. The connecting rod rotates synchronously with the raising and lowering of the lead glass protective screen 2, thereby driving several foldable lead plates 301 to extend, retract, and fold: when the device is raised to fit a higher examination bed or a tall patient, the connecting rod pushes the foldable lead plate 301 to extend, ensuring that the enclosed lead apron 3 always covers the perimeter of the operating side of the main frame 1, achieving 360-degree protection without blind spots; when the device is lowered to fit a lower examination bed or a small patient, the connecting rod pulls the foldable lead plate 301 to fold and retract, avoiding the lead apron being too long and obstructing the operation or causing wear and tear.
[0045] Meanwhile, the foldable lead plates 301 of the enclosed lead apron 3 adopt an overlapping sealing structure, and an elastic lead pad is embedded at the overlap. The elastic lead pad fits tightly with the foldable lead plates 301 on both sides. No gaps will be generated whether the lead plates are extended or folded, effectively preventing high-energy radioactive rays such as 18F from penetrating through the gaps. Compared with the protection method of simply wearing a lead apron, the protection effect is greatly improved. At the same time, it replaces the wearing of heavy lead aprons and significantly reduces the physical exertion of medical staff.
[0046] When the lifting linkage module is adjusted to the preset height threshold (maximum or minimum limit height), the control module detects the lifting position signal in real time and simultaneously triggers the self-locking structure of the universal pulley, locking the universal pulley in place and preventing the device from tipping over when operating at the limit height. This achieves automatic linkage between lifting and positioning, solving the problems of easy sliding after movement and poor stability at the limit height of existing movable protective devices, thus improving the safety of the operation process.
[0047] After the height adjustment is completed, medical staff will insert their arms into the symmetrical lead apron sleeve operation holes 10 on both sides of the main frame 1, observe the operation area through the lead glass protective screen 2, and complete the bedside injection of radiopharmaceuticals. After the injection is completed, the medical staff will control the drive component 6 to rotate in reverse through the control module, drive the lifting linkage module to reset, and simultaneously unlock the universal pulley self-locking structure. Then, the main frame 1 will be pushed to move the device to the next injection position or storage area. The entire implementation process is convenient to operate and smooth in linkage, and is suitable for various bedside injection scenarios in nuclear medicine departments.
[0048] Example 2:
[0049] The difference from Embodiment 1 is that a functional integration module is also installed on the main frame 1. The functional integration module includes an external waste lead container 4 and a doctor-patient communication speaker. The external waste lead container 4 is used to collect radioactive waste after injection, and the doctor-patient communication speaker is used to solve the problem of inconvenient doctor-patient communication after the protective module is blocked. A sealing cover is provided at the opening of the external waste lead container 4. One side of the sealing cover is hinged to the opening of the external waste lead container 4, and a return spring is provided at the hinge between the sealing cover and the opening.
[0050] The functional integration module also includes a placement component for placing single-use radiopharmaceutical canisters. The placement component includes a lead placement base 9, a limiting clamp, and a protective cover. The lead placement base 9 has an arc-shaped groove 901 inside that matches the single-use radiopharmaceutical canister. The inner wall of the arc-shaped groove 901 is equipped with a buffer anti-slip pad. The limiting clamp is hinged to the top of the lead placement base 9 and is used to clamp and secure the single-use radiopharmaceutical canister. The protective cover is hinged to the lead placement base 9, and an electromagnetic lock is installed between the protective cover and the lead placement base 9. A pressure sensor is installed inside the operating hole 10 of the lead apron sleeve. Both the pressure sensor and the electromagnetic lock are connected to the control module. When a medical staff member inserts their arm into the operating hole and presses the pressure sensor, the control module controls the electromagnetic lock to unlock, simultaneously triggering the automatic opening of the protective cover.
[0051] The doctor-patient communication loudspeaker includes several radio amplification units, which are respectively installed on both sides of the lead glass protective screen 2. The doctor-patient communication loudspeaker is connected to the control module. When the control module determines that the pressure sensor detects that a medical staff member's arm has entered the operating hole, the control module automatically starts the doctor-patient communication loudspeaker. When the arm is pulled out of the operating hole, the doctor-patient communication loudspeaker automatically turns off.
[0052] The specific implementation process is as follows: Place the single-use radiopharmaceutical container into the placement assembly of the functional integration module in advance. Lift the limiting clamp on the top of the lead placement base 9 and place the container into the arc-shaped groove 901 inside the lead placement base 9 that matches the container. The buffer anti-slip pad on the inner wall of the arc-shaped groove 901 can tightly fit the outer wall of the container, preventing the container from sliding or colliding during device movement or operation. Then, lower the limiting clamp and use its clamping force to fix the container. Finally, close the protective cover. The electromagnetic lock between the protective cover and the lead placement base 9 automatically locks, achieving sealed protection of the container, preventing premature exposure of the radiopharmaceutical, reducing the risk of radiation exposure for medical personnel, and further blocking radiation to meet the protection requirements of high-energy nuclides such as 18F.
[0053] After the device in Example 1 is moved into place, the lifting height is adjusted, and the universal pulley is self-locked, the medical staff inserts their arm into the operating hole 10 of the lead apron sleeve and presses the pressure sensor inside the operating hole. The pressure sensor immediately sends a signal to the control module, and the control module simultaneously executes two linked operations: First, it controls the electromagnetic lock between the protective cover and the lead placement seat 9 to unlock and triggers the protective cover to open automatically, eliminating the need for medical staff to manually unlock and lift the protective cover, simplifying the operation steps and reducing the contact time between medical staff and radiopharmaceuticals; Second, it activates the doctor-patient communication speaker, so that the sound receiving and amplification units on both sides of the lead glass protective screen 2 work synchronously, eliminating the need for medical staff to manually turn on the speaker, and realizing the automatic linkage of operation and communication functions.
[0054] During the injection procedure, communication between medical staff and patients is hindered due to the enclosed lead apron 3 and lead glass protective screen 2 of the protective module. At this time, the sound amplification unit of the medical staff communication speaker can achieve clear two-way communication: the patient's voice is collected and amplified by the sound amplification unit on the patient side of the lead glass protective screen 2 and transmitted to the medical staff; the instructions of the medical staff are collected and amplified by the sound amplification unit on the medical staff side and transmitted to the patient. This effectively solves the problem of inconvenient medical staff communication caused by the obstruction of the protective module, and at the same time avoids medical staff from getting close to the patient for communication, further reducing the radiation dose.
[0055] After injection, medical staff do not need to withdraw their arms and can directly discard the injected radioactive waste (such as syringes, needles, etc.) into the external waste lead container 4 of the functional integrated module. Pressing the sealing cap at the opening of the external waste lead container 4 will open the sealing cap by rotating it around the hinge point. After disposal, the return spring at the hinge point will drive the sealing cap to close automatically, realizing the rapid collection of waste and avoiding radiation leakage during waste transportation. At the same time, medical staff do not need to manually close the sealing cap, simplifying the operation and reducing the risk of radiation exposure. The lead structure of the external waste lead container 4 can effectively block radiation and further improve the safety of protection.
[0056] Once the injection is complete, after the medical staff removes their arm from the operating port 10 of the lead apron sleeve, the pressure sensor stops sending signals, and the control module simultaneously triggers two reset operations: first, it controls the automatic shut-off of the doctor-patient communication speaker to avoid noise interference caused by the speaker being on for a long time, without the need for manual shut-off; second, it controls the automatic closing of the protective cover of the placement component, and the electromagnetic lock locks simultaneously to seal and protect the remaining drug container (if any) to prevent drug exposure.
[0057] After the entire injection process is completed, if it is necessary to transfer the external waste lead container 4, the external waste lead container 4 can be directly disassembled for transfer; if it is necessary to continue to inject the next patient, simply repeat the above operations of placing the drug container, inserting the arm to trigger the linkage, and discarding the waste. The functional integration module is designed to link the various components with the control module and the protection module.
[0058] Example 3:
[0059] The difference from Embodiment 2 is that a liftable injection stage is also provided in the middle of the main frame 1. The injection stage is fixedly connected to the linkage bracket and rises and falls synchronously with the lifting linkage module.
[0060] The specific implementation process is as follows: First, following the operation procedure of Example 1, the device is moved to the side of the target examination bed. The lifting linkage module is activated through the control module. Since the injection table is fixedly connected to the linkage bracket, when the drive component 6 drives the transmission component to move and the linkage bracket is raised and lowered synchronously, the injection table is raised and lowered together with the linkage bracket, realizing synchronous linkage with the lead glass protective screen 2 and the enclosed lead apron 3. There is no need to adjust the height of the injection table separately, which solves the defects of the existing device where the height of the injection table and the protective components are disconnected and the adjustment is cumbersome, and greatly improves the operating efficiency.
[0061] During the lifting and lowering process, the control module adjusts the drive component 6 in real time to ensure that the height of the injection table is always adapted to the examination bed and the patient's position. Medical staff can clearly observe the injection table surface through the lead glass protective screen 2, facilitating the placement of radioactive drugs and injection equipment and avoiding clutter and operational errors caused by the lack of a dedicated operating surface. The injection table uses a lead surface, which can further block high-energy radioactive rays such as 18F. Combined with the enveloping lead apron 3, it forms double protection, further reducing the radiation dose to medical staff and improving safety.
[0062] Example 4:
[0063] The difference from Embodiment 3 is that the lead apron sleeve operation hole 10 is also circumferentially provided with several rotatable lead baffles. The lead baffles are hinged to the side wall of the lead apron sleeve operation hole 10, and a torsion spring is provided at the hinge point between the lead baffles and the lead apron sleeve operation hole 10. The torsion spring is used for the automatic reset of the lead baffles. When the medical staff's arm is inserted into the lead apron sleeve operation hole 10, it drives the lead baffles to rotate, thereby blocking the radiation blind zone around the lead apron sleeve operation hole 10. When the medical staff's arm is pulled out of the lead apron sleeve operation hole 10, the lead baffles automatically reset.
[0064] The specific implementation process is as follows: First, following the operating procedure of Example 1, the device is moved to the side of the target examination bed, and the lifting height is adjusted and the universal pulleys are self-locked to ensure that the operating hole 10 of the lead apron sleeve is at a height suitable for medical personnel to operate. Lead baffles are evenly distributed around the side wall of the operating hole 10 of the lead apron sleeve. In the initial state, under the elastic force of the torsion spring, the lead baffles are in a closed state, tightly fitting the inner wall of the operating hole, completely blocking the gap around the operating hole, preventing high-energy radioactive rays such as 18F from leaking through the gap of the operating hole when not in use, and filling the protection blind spot around the operating hole of the existing device.
[0065] Once ready, the medical staff slowly inserts their arm into the operating hole 10 of the lead apron sleeve. The arm contacts the lead baffle and applies a slight pushing force, causing the lead baffle to rotate around the hinge point with the side wall of the operating hole. The torsion spring simultaneously undergoes elastic deformation and stores elastic force. During the rotation, the lead baffle remains in contact with the surface of the arm and adaptively adjusts the rotation angle according to the depth of the arm insertion, completely blocking the gap between the arm and the operating hole.
[0066] During the injection procedure, regardless of the angle at which the medical staff adjusts their arm, the lead shield will remain tightly fitted to the arm under the elastic force of the torsion spring, continuously blocking the radiation blind spot. Combined with the enveloping lead apron 3 and the lead glass protective screen 2, this forms all-around protection, effectively blocking radiation and reducing the radiation dose received by the medical staff. In conjunction with embodiments 2 and 3, when the arm is inserted, triggering the pressure sensor, the lead shield simultaneously completes the blind spot blocking, achieving synergy between protection and function.
[0067] After the injection is completed, the medical staff slowly withdraws their arm. The pushing force on the lead shield disappears, the torsion spring releases its stored elasticity, and drives the lead shield to rotate in the opposite direction around the hinge point, automatically resetting to the initial closed state and covering the gap around the operating hole again.
[0068] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
