Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical packaging, specifically a PET radioactive pharmaceutical packaging and protection device for radiation protection. Background Technology
[0002] PET radiopharmaceuticals are radioactive tracers used in positron emission tomography (PET) scans, playing a crucial role in the process. These drugs are typically composed of radioactive isotopes that emit gamma rays within the body that can be detected by external detectors, thus enabling the imaging of biological processes. In recent years, with the development of nuclear medicine, the use of PET radiopharmaceuticals has become increasingly widespread, especially in fields such as cancer diagnosis and treatment monitoring.
[0003] In the existing technology, PET radiopharmaceutical repackaging refers to the process of repackaging radiopharmaceuticals into suitable syringes in a specific environment according to a certain ratio and procedure so that they can be used in PET examinations. Protection is required during repackaging to reduce unnecessary dose exposure. However, most protective shells can only repack one syringe at a time, resulting in low repackaging efficiency. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, most protective shells can only dispense one syringe at a time, resulting in low dispensing efficiency. This invention proposes a PET radioactive drug dispensing and protective device for radiation protection.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a PET radioactive drug dispensing and protection device for radiation protection, including a support frame, a protective shell fixedly connected to one side of the support frame, an injector disposed inside the protective shell, a fixed plate and a stop block fixedly connected inside the protective shell, and a clamping mechanism disposed on the outside of the injector.
[0006] The clamping mechanism includes a first hollow groove formed on the top of the support frame. A slide rod is slidably connected inside the first hollow groove. A hollow block is fixedly connected to the top of the slide rod. A threaded rod is rotatably connected to the inner cavity of the hollow block. A first clamping block and a second clamping block are threadedly connected to the surface of the threaded rod. A limit rod is slidably connected to one side of the support frame. The first clamping block and the second clamping block are slidably connected to the surface of the limit rod.
[0007] Preferably, a second hollow groove is provided on one side of the support frame, and a sliding block is slidably connected inside the second hollow groove. One side of the sliding block is fixedly connected to one side of the limiting rod.
[0008] Preferably, one end of the threaded rod is fixedly connected to a fixing rod, and the surface of the fixing rod is provided with anti-slip texture, and a plurality of anti-slip textures are provided.
[0009] Preferably, a limiting ring is provided on one side of the hollow block, and the inner cavity of the limiting ring is fixedly connected to the surface of the threaded rod.
[0010] Preferably, a fixing block is fixedly connected to one end of the threaded rod, and the diameter of the fixing block is larger than the diameter of the threaded rod.
[0011] Preferably, a reinforcing rod is fixedly connected to one side of the hollow block, and the bottom of the reinforcing rod is fixedly connected to the top of the sliding rod.
[0012] Preferably, an L-shaped pull rod is fixedly connected to the top of the second clamping block, and a rubber sleeve is fixedly connected to the surface of the L-shaped pull rod.
[0013] The advantages of this utility model are:
[0014] This invention utilizes a rotating threaded rod. Due to the opposite threads on both sides of the threaded rod, the first and second clamping blocks move in opposite directions. Simultaneously, the first and second clamping blocks slide on the surface of a limiting rod. After the first and second clamping blocks move, they clamp the piston handle of the syringe. At this point, sliding the slide rod upwards causes the hollow block, the first clamping block, and the second clamping block to move upwards together, thereby moving the syringe and achieving the effect of extracting PET radioactive drugs. Furthermore, multiple syringes can be provided, allowing multiple syringes to be extracted at once, thus improving the dispensing efficiency and solving the problem that most protective shells can only dispense one syringe at a time, resulting in low dispensing efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0025] This application discloses a PET radiopharmaceutical packaging and protective device for radiation protection. (Refer to...) Figure 1-5 A radiation protection device for dispensing PET radiopharmaceuticals includes a support frame 1. A protective shell 2 is fixedly connected to one side of the support frame 1. A syringe 3 is disposed inside the protective shell 2. A fixing plate 4 and a stop block 5 are fixedly connected inside the protective shell 2. A clamping mechanism is provided on the outside of the syringe 3. Multiple protective shells 2 are connected in the middle of the support frame 1. The syringe 3 can be placed inside the multiple protective shells 2. The syringe 3 can be used to extract PET radiopharmaceuticals. The fixing plate 4 can be used to support the bottom of the handle of the syringe 3. The syringe 3 can be rotated so that the handle is located at the bottom of the stop block 5. At this time, the syringe 3 is fixed and can be pulled up and down to extract the medicine.
[0026] The clamping mechanism includes a first hollow slot 601 formed in the top of the support frame 1. A slide rod 602 is slidably connected inside the first hollow slot 601. A hollow block 603 is fixedly connected to the top of the slide rod 602. A threaded rod 604 is rotatably connected to the inner cavity of the hollow block 603. A first clamping block 605 and a second clamping block 606 are threadedly connected to the surface of the threaded rod 604. A limit rod 607 is slidably connected to one side of the support frame 1. The first clamping block 605 and the second clamping block 606 are slidably connected to the surface of the limit rod 607.
[0027] The hollow block 603 can be used to support the threaded rod 604, allowing the threaded rod 604 to rotate on top of the slide bar 602. The threads on both sides of the threaded rod 604 are opposite, so that when the threaded rod 604 rotates, it can drive the first clamping block 605 and the second clamping block 606 to move in opposite directions. The first clamping block 605 and the second clamping block 606 have a recessed portion in the middle, allowing them to clamp multiple syringes 3 after moving in opposite directions. The interior of the first hollow groove 601 can be used to place the slide bar 602. The rod 602 allows the slide rod 602, the first clamping block 605, and the second clamping block 606 to move upward. When the first clamping block 605 and the second clamping block 606 move upward, they can drive multiple syringes 3 to move together at once, so that multiple syringes 3 can simultaneously draw radioactive drugs, improving dispensing efficiency. The limiting rod 607 can limit the first clamping block 605 and the second clamping block 606, so that when the threaded rod 604 rotates, the first clamping block 605 and the second clamping block 606 can move smoothly and are not prone to rotation.
[0028] Reference Figure 6 A second hollow groove 12 is provided on one side of the support frame 1. A sliding block 13 is slidably connected inside the second hollow groove 12. One side of the sliding block 13 is fixedly connected to one side of the limiting rod 607. The sliding block 13 can be placed inside the second hollow groove 12, and the limiting rod 607 is limited by the sliding block 13, so that when the limiting rod 607 slides on one side of the support frame 1, it is not easy to detach from the support frame 1, and it is more stable.
[0029] Reference Figure 5 One end of the threaded rod 604 is fixedly connected to a fixing rod 7. The surface of the fixing rod 7 is provided with anti-slip textures 8. Several anti-slip textures 8 are provided. The fixing rod 7 can prevent people from being accidentally injured by the threads on the surface of the threaded rod 604 when rotating it, while the anti-slip textures 8 can play an anti-slip role, making it less likely for people to slip when rotating the fixing rod 7 and causing difficulty in rotation.
[0030] Reference Figure 5A limiting ring 9 is provided on one side of the hollow block 603. The inner cavity of the limiting ring 9 is fixedly connected to the surface of the threaded rod 604. There are two limiting rings 9, located on both sides of the hollow block 603 respectively. They can limit the threaded rod 604, so that the threaded rod 604 is not easy to move when it rotates inside the hollow block 603. This makes the first clamping block 605 and the second clamping block 606 more stable.
[0031] Reference Figure 5 A fixing block 10 is fixedly connected to one end of the threaded rod 604. The diameter of the fixing block 10 is larger than the diameter of the threaded rod 604. The fixing block 10 can limit the second clamping block 606, so that the second clamping block 606 is not easy to detach from the threaded rod 604 when it moves on the surface of the threaded rod 604.
[0032] Reference Figure 5 A reinforcing rod 11 is fixedly connected to one side of the hollow block 603. The bottom of the reinforcing rod 11 is fixedly connected to the top of the slide rod 602. The reinforcing rod 11 can reinforce the hollow block 603, making it less likely for the hollow block 603 to break at the top of the slide rod 602, thereby extending the service life of the hollow block 603.
[0033] Reference Figure 1 The top of the second clamping block 606 is fixedly connected to an L-shaped pull rod 14, and a rubber sleeve 15 is fixedly connected to the surface of the L-shaped pull rod 14. The L-shaped pull rod 14 makes it easy for people to pull the second clamping block 606 upward, which in turn makes it easier to move multiple syringes 3 together, making the movement of multiple syringes 3 more convenient and faster.
[0034] Working principle: When using this device, first place the syringe 3 inside the protective shell 2, and position the handle of the syringe 3 at the top of the fixed plate 4. Then rotate the handle of the syringe 3 to the bottom of the stop block 5, at which point the syringe 3 is fixed. Then rotate the threaded rod 604. Due to the opposite threads on both sides of the threaded rod 604, the first clamping block 605 and the second clamping block 606 will move in opposite directions. At the same time, the first clamping block 605 and the second clamping block 606 will slide on the surface of the limiting rod 607. After the first clamping block 605 and the second clamping block 606 move, they will clamp the piston handle of the syringe 3. At this time, slide the slide rod 602 upward. The slide rod 602 will drive the hollow block 603 and the first clamping block 605 and the second clamping block 606 to move upward together, thereby driving the syringe 3 to move, so as to achieve the effect of extracting PET radioactive drugs. Since multiple syringes 3 are provided, multiple can be extracted at one time, thereby improving the dispensing efficiency. This solves the problem that most protective shells can only dispense one syringe 3 at a time, resulting in low dispensing efficiency.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
