Description

Technical Field

[0001] This utility model relates to the field of medical radioactive material protection technology, specifically a multifunctional radiopharmaceutical storage device for nuclear medicine nursing. Background Technology

[0002] Medical radioactive material protection refers to a series of comprehensive technical and management measures taken to protect medical personnel, patients, and the public from the hazards of ionizing radiation generated during the production, use, storage, transportation, and disposal of medical radioactive materials.

[0003] An existing patent (publication number: CN218768765U) discloses a radiopharmaceutical storage and dispensing device, including a container (1), a container lid (2), and an extension tube (5) for connecting the radiopharmaceutical to an injection needle; the container (1) is a lead cylinder, and its inner cavity is a radiopharmaceutical placement cavity (11) for storing radiopharmaceuticals. The upper part of the side wall of the radiopharmaceutical placement cavity (11) extends outward to form an extension tube receiving cavity (12) for placing the extension tube (5); the container lid (2) has a container lid opening (21), and a sealing cap (3) is installed on the container lid opening (21) to seal it. The sealing cap (3) matches the shape and size of the container lid opening (21); the sealing head (53) matches the shape and size of the container lid opening (21). This utility model greatly reduces the accidental volatilization and excessive exposure of radiopharmaceuticals during use, and protects the personal safety of medical personnel to the greatest extent.

[0004] The aforementioned storage device can significantly reduce the accidental volatilization and excessive exposure of radiopharmaceuticals during use, thus maximizing the protection of medical personnel's personal safety. However, during use, it is necessary to put one's hand into the container, remove the sealing cap, and perform a series of operations inside the container, which increases the risk of radiation exposure for medical personnel. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a multifunctional radiopharmaceutical storage device for nuclear medicine nursing, which has advantages such as reducing the risk of medical personnel being exposed to radioactive materials when retrieving medications, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional radiopharmaceutical storage device for nuclear medicine nursing, comprising an upper storage tank and a lower storage tank, wherein the upper storage tank and the lower storage tank are slidably connected, a lead bottle is provided between the upper storage tank and the lower storage tank, and a lead cap is threadedly connected to the upper end of the lead bottle, wherein a plurality of circumferentially distributed protrusions are formed on the outer surface of the lead cap.

[0007] The upper storage tank is rotatably connected to a rotating cap via a bearing at its upper end along its axis. The bottom end of the rotating cap forms a slide rail with the upper end of the upper storage tank. A rotating ring is rotatably connected between the two slide rails. The bottom end of the rotating ring is slidably connected to the slide rail. Multiple sliding rods are slidably inserted into the outer circumference of the rotating ring. One end of each sliding rod is fixedly connected to a clamp. Each clamp is arc-shaped on one side of the lead cap and has a protruding structure that matches the protrusion. A slot is opened at the upper end of the rotating cap away from the central area. A guide tube is fixedly connected to the inner wall of the slot.

[0008] Furthermore, the end of each slide rod away from the clamping plate is spherical, and the inner wall of the rotating cap is fixedly connected with a plurality of circumferentially distributed extrusion blocks, and the spherical end of each slide rod is in contact with the corresponding extrusion block.

[0009] With the above scheme, when the rotating cap rotates, the extrusion block will rotate synchronously with the rotating cap. During the rotation, the extrusion block will exert an extrusion force on the spherical end of the slide rod. Due to the spherical end design of the slide rod, the contact between the extrusion block and the slide rod is smoother, reducing frictional resistance. At the same time, it can more effectively transmit the rotational force of the rotating cap to the slide rod, thereby driving the movement of the clamping plate.

[0010] Furthermore, a limiting ring is fixedly connected to the outer circumferential surface of the upper storage tank, and multiple arc-shaped notches are opened on the outer surface of the limiting ring. Multiple elastic metal clips are fixedly connected to the outer circumferential surface of the rotating cap, and each elastic metal clip is located within the arc-shaped notch.

[0011] Through the above scheme, the limiting ring and the arc-shaped notch provide specific positional restrictions for the elastic metal clip. When the rotating cap rotates to a certain angle, the elastic metal clip will be inserted into the arc-shaped notch, which plays a role in positioning and limiting, preventing the rotating cap from rotating accidentally under non-human operation.

[0012] Furthermore, multiple support plates are hinged to the outer circumferential surface of the bottom end of the upper storage tank. The multiple support plates are distributed in a circle, and the lower end of each support plate is vertically downward under gravity.

[0013] With the above solution, the support plate can be set up so that when the upper storage tank slides on the lower storage tank, the support column abuts against the upper end of the lower storage tank, thereby separating the lead cap held by the clamp from the lead bottle, making it easier for staff to retrieve medicine.

[0014] Furthermore, the upper and lower storage tanks are connected by snap-fit ​​connections.

[0015] With the above solution, the snap-fit ​​connection between the upper and lower storage tanks allows for easy separation of the two parts when it is necessary to open the upper and lower storage tanks to separate the lead caps and lead bottles. This facilitates the removal of the lead bottle inside the lower storage tank. At the same time, the snap-fit ​​connection ensures that the upper and lower storage tanks are firmly connected during normal use and will not easily separate, ensuring that the lead bottle is always kept in a closed storage environment.

[0016] Furthermore, a plurality of force-bearing rods are fixedly connected to the outer surface of the rotating cap, and a plug is inserted into the inside of the slot, the plug being in contact with the upper surface of the rotating cap.

[0017] With the above scheme, the force-bearing rod provides a convenient point of leverage for the operator to rotate the rotating cap. The operator can apply rotational force by holding the force-bearing rod, making it easier to rotate the rotating cap and complete operations such as disassembling the lead cap. The stopper is used to seal the slot. When it is not necessary to extract radiopharmaceuticals, the stopper is inserted into the slot to prevent external impurities from entering the lead bottle and contaminating the radiopharmaceuticals. At the same time, it further enhances the sealing of the device.

[0018] Furthermore, a spring is fixedly connected to one side of each clamp plate facing away from each other, and the other end of each spring is fixedly connected to the inner wall of the upper storage tank.

[0019] With the above solution, when the lead cap is removed and the rotating cap is rotated in the opposite direction, the spring can use its own elastic force to push the clamp back to the initial position, preparing for the next operation.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This multifunctional radiopharmaceutical storage device for nuclear medicine care features a clamp that, when the cap is rotated, allows the protruding structure of the clamp to contact a protrusion and hold the lead cap in place. Continued rotation of the cap removes the lead cap from the lead bottle, allowing it to slide onto the upper storage tank along the axis of the lower tank, separating the cap from the bottle. Once separated, an infusion tube can be inserted into the bottle through a guide tube via a slot to extract the radiopharmaceutical. Because the lead bottle does not need to be exposed during extraction—the upper and lower storage tanks remain sealed—and extraction is only done through the infusion tube inserted into the slot, the risk of radiation exposure to radioactive materials is significantly reduced, thus improving operational safety.

[0029] 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.

[0030] Please see Figures 1-5 This embodiment describes a multifunctional radiopharmaceutical storage device for nuclear medicine care, comprising an upper storage tank 1 and a lower storage tank 2, which are slidably connected. A lead bottle 3 is disposed between the upper storage tank 1 and the lower storage tank 2. A lead cap 4 is threadedly connected to the upper end of the lead bottle 3. The bottom end of the lead bottle 3 has a raised rhomboid structure and is slidably inserted into the inner bottom wall of the lower storage tank 2. The lead bottle 3 and the lead cap 4 are threadedly connected to seal the lead bottle 3 and prevent the internal radiopharmaceutical from leaking out. Both the lead bottle 3 and the lead cap 4 have good radiation shielding performance and can play a significant shielding role against radioactive rays. The outer surface of the lead cap 4 has multiple circumferentially distributed protrusions.

[0031] The upper storage tank 1 is rotatably connected to a rotating cap 5 via a bearing at its upper end along its axis. The bottom end of the rotating cap 5 forms a slide rail with the upper end of the upper storage tank 1. A rotating ring 18 is rotatably connected between the two slide rails. The bottom end of the rotating ring 18 is slidably connected to the slide rail. Multiple sliding rods 6 are slidably inserted into the outer circumference of the rotating ring 18. A clamping plate 7 is fixedly connected to one end of each sliding rod 6. Each clamping plate 7 is arc-shaped on one side of the lead cover 4 and has a protruding structure that matches the protrusion. A slot 8 is opened at the upper end of the rotating cap 5 away from the central area. A guide tube 9 is fixedly connected to the inner wall of the slot 8.

[0032] Each slide rod 6 has a spherical end away from the clamping plate 7. The inner wall of the rotating cap 5 is fixedly connected with multiple circumferentially distributed extrusion blocks 10. The spherical end of each slide rod 6 is in contact with the corresponding extrusion block 10. Since the rotating ring 18 rotates with the upper storage tank 1 via the slide rail and the rotating cap 5, the rotating ring 18 will be subject to friction during rotation and will not be easy to rotate. During the rotation of the rotating cap 5, the extrusion block 10 can push the slide rod to slide on the rotating ring 18. When the slide rod 6 is in position, the extrusion block 10 pushes the slide rod 6 to drive the rotating ring 18 to rotate. When the rotating cap 5 rotates, the extrusion block 10 will rotate synchronously with the rotating cap 5. During the rotation, the extrusion block 10 will exert an extrusion force on the spherical end of the slide rod 6. Due to the spherical end design of the slide rod 6, the contact between the extrusion block 10 and the slide rod 6 is smoother, reducing frictional resistance, and at the same time, it can more effectively transmit the rotational force of the rotating cap 5 to the slide rod 6, thereby driving the clamping plate 7 to move.

[0033] A limiting ring 11 is fixedly connected to the outer circumferential surface of the upper storage tank 1. The outer surface of the limiting ring 11 has multiple arc-shaped notches 12. Multiple elastic metal clips 13 are fixedly connected to the outer circumferential surface of the rotating cap 5. Each elastic metal clip 13 is located within the arc-shaped notch 12. The limiting ring 11 and the arc-shaped notch 12 provide specific positional restrictions for the elastic metal clips 13. When the rotating cap 5 rotates to a certain angle, the elastic metal clips 13 will be inserted into the arc-shaped notch 12, which plays a role in positioning and limiting, preventing the rotating cap 5 from rotating accidentally under non-human operation. Multiple support plates 14 are hinged to the outer circumferential surface of the bottom end of the upper storage tank 1. The multiple support plates 14 are circumferentially distributed. The lower end of each support plate 14 is vertically downward under gravity. The support plates 14 are set so that when the upper storage tank 1 slides on the lower storage tank 2, the support column abuts against the upper end of the lower storage tank 2, thereby separating the lead cap 4 held by the clip 7 from the lead bottle 3, which facilitates the staff to take medicine.

[0034] The upper storage tank 1 and the lower storage tank 2 are connected by a snap-fit ​​mechanism. This snap-fit ​​connection allows for easy separation of the two parts when it is necessary to open the upper storage tank 1 and the lower storage tank 2 to separate the lead cap 4 from the lead bottle 3. This facilitates the removal of the lead bottle 3 from the lower storage tank 2. At the same time, the snap-fit ​​connection ensures that the upper storage tank 1 and the lower storage tank 2 are firmly connected during normal use and will not easily separate, ensuring that the lead bottle 3 is always kept in a closed storage environment.

[0035] Multiple force-bearing rods 15 are fixedly connected to the outer surface of the rotating cap 5. A stopper 16 is inserted into the inside of the slot 8. The stopper 16 contacts the upper surface of the rotating cap 5. The force-bearing rods 15 provide convenient leverage points for the operator to rotate the rotating cap 5. The operator can apply rotational force by holding the force-bearing rods 15, making it easier to rotate the rotating cap 5 and complete operations such as disassembling the lead cover 4. The stopper 16 is used to seal the slot 8. When it is not necessary to extract radiopharmaceuticals, the stopper 16 is inserted into the slot 8 to prevent external impurities from entering the lead bottle 3 and contaminating the radiopharmaceuticals. It also further enhances the sealing of the device. A spring 17 is fixedly connected to one side of each clamp 7 facing away from each other. The other end of each spring 17 is fixedly connected to the inner wall of the upper storage tank 1. When the disassembly of the lead cover 4 is completed and the rotating cap 5 rotates in the opposite direction, the spring 17 can push the clamp 7 back to the initial position by its own elastic force, preparing for the next operation.

[0036] The working principle of the above embodiment is as follows: First, when it is necessary to remove the radiopharmaceutical from the lead bottle 3, the staff removes the buckle connection between the upper storage tank 1 and the lower storage tank 2. Then, the staff rotates the rotating cap 5 through the force rod 15. Since the rotating ring 18 rotates with the upper storage tank 1 through the slide rail and the rotating cap 5, the rotating ring 18 will be subject to friction during the rotation of the rotating cap 5 and will not easily rotate. During the rotation, the rotating cap 5 can push the corresponding slide rod 6 to slide on the rotating ring 18 through multiple squeezing blocks 10. When the multiple slide rods 6 are in place, the multiple clamping plates 7 contact the lead cover 4, so that the protruding structure on the clamping plate 7 can be embedded between the multiple protrusions on the lead cover 4. Then, the rotating cap 5 is rotated again, and the squeezing blocks 10 push the slide rods 6 to drive the rotating ring 18 to rotate. Since the clamping plates 7 are in contact with the lead bottle 3, the multiple clamping blocks can hold the lead cover 4 in place during the rotation of the rotating ring 18. After the lead cap 4 is removed, multiple elastic metal clips 13 can be positioned within the corresponding arc-shaped notches 12 to limit the rotation cap 5 and prevent it from rotating without external force. During the removal of the lead cap 4, the upper storage tank 1 can slide along the axial direction of the lower storage tank 2 without separating the two. The operator swings the bottom ends of multiple support plates 14 so that the multiple support plates 14 abut against the upper end of the lower storage tank 2, thereby supporting the upper storage tank 1. During this process, the distance between the lead cap 4 and the lead bottle 3 will increase. The operator removes the stopper 16, inserts the infusion tube through the slot hole 8 and the guide tube 9 into the inside of the lead bottle 3, and extracts the radiopharmaceutical inside the lead bottle 3. During the extraction process, the lead bottle 3 will remain in a closed state, and the drug will be extracted only through the slot hole 8, reducing the risk of the operator being exposed to radioactive materials and thus improving the safety of the operation.
