A temporary protective box for storing discarded synthesizer cartridges

Abstract

This utility model relates to a temporary protective box for storing discarded synthesizer ferrules, comprising a box body with a receiving cavity inside, a placement opening at the top of the box body, and a mounting base at the top of the box body. The mounting base is connected to a drive mechanism that drives the mounting base to move between a first position exposing the placement opening and a second position covering the placement opening. The protective box also includes a detection device and a control unit that controls the drive mechanism to move the mounting base according to the detection device. A pushing member is provided at the bottom of the mounting base. By controlling the movement of the mounting base through the control unit, the falling ferrules fall into the receiving cavity, and the pushing member moves the ferrules below the placement opening into the receiving cavity, ensuring that they do not affect the automatic loading of multiple batches of synthesizers. At the same time, the control unit controls the mounting base to cover the placement opening after the ferrule falls into the receiving cavity, thereby reducing the radiation dose from discarded ferrules received by operators during the manual installation of new ferrules for a single batch of synthesizers.

Description

Technical Field

[0001] This utility model relates to the field of drug synthesis, specifically to a temporary protective box for storing discarded synthesizer cassettes. Background Technology

[0002] Automated synthesizers are widely used in the preparation of nuclear medicine preparations. Single-batch synthesizers are typically used for small-batch, highly flexible synthesis tasks, while multi-batch synthesizers are suitable for continuous production.

[0003] In existing synthesizer workflows, disposable cassettes are typically used to carry radioactive precursors to synthesize the target compound. After synthesis, the discarded cassettes are pushed into a collection area directly in front of the synthesizer. Once a certain number of discarded cassettes have accumulated in the collection area, they are transferred to a dedicated radioactive waste storage container. However, a certain dose of radioactive material remains in the discarded cassettes. When operators manually install new cassettes on a single-batch synthesizer, they will receive a certain external radiation dose from the discarded cassettes. At the same time, for multi-batch automated synthesizers, if the collection area is not cleaned in a timely manner, discarded cassettes can easily accumulate. When the accumulation reaches a certain level, it may block the loading of new cassettes, causing automatic loading failure and affecting the continuity and stability of the entire synthesis process.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 5 As shown, this utility model discloses a temporary protective box for storing discarded synthesizer ferrules, including a box body 1. The box body 1 has a receiving cavity 11 for accommodating ferrules. The upper part of the box body 1 is provided with a placement opening 12 communicating with the receiving cavity 11. The upper part of the box body 1 is provided with a mounting base 2 for installing synthesizers. The mounting base 2 is connected to a drive mechanism 3 that drives it to move between a first position exposing the placement opening 12 and a second position covering the placement opening 12. The protective box also includes a detection device 4 and a control unit 5 that can control the drive mechanism 3 to drive the mounting base 2 to move to the first position when the detection device 4 detects that the ferrule is in a preset position, and control the drive mechanism 3 to drive the mounting base 2 to move to the second position after the ferrule enters the receiving cavity 11. The lower part of the mounting base 2 is provided with a pusher 6 that drives the ferrule below the placement opening 12 away from the placement opening 12 during the process of the mounting base 2 moving to the first position. When the mounting base 2 is in the first position, the pusher 6 restricts the ferrule after moving away from the placement opening 12 from approaching the lower part of the placement opening 12.

[0021] The housing 1 has an internal cavity 11 for accommodating discarded card sleeves. The upper part of the housing 1 has a placement opening 12 communicating with the cavity, through which discarded card sleeves fall. The cavity 11 centrally stores discarded card sleeves, preventing them from being exposed to the external environment and causing contamination or hindering operation. The housing 1 and the mounting base 2 are made of protective material. The mounting base 2 can move between a first position and a second position. When in the first position, the placement opening 12 is exposed, facilitating the falling of card sleeves; when in the second position, the placement opening 12 is covered, reducing the exposure of discarded card sleeves in the cavity to the external environment. In this embodiment, the synthesizer's card sleeve ejection mechanism is positioned appropriately on the mounting base 2, so that when the mounting base 2 is in the first position, the ejection mechanism pushes out the card sleeve, allowing it to fall into the cavity 11 through the placement opening 12, ensuring a smooth fall. A drive mechanism 3 can drive the mounting base to move between the first and second positions. In this embodiment, the drive mechanism 3 is implemented using a cylinder, but it can also be implemented using an electric push rod, a servo motor, and a guide rail. The detection device 4 can be implemented using photoelectric sensors, proximity switches, image recognition systems, etc., to achieve automated response. In this embodiment, the detection device 4 is a photoelectric sensor installed below the card sleeve ejection mechanism of the synthesizer. It senses whether the card sleeve ejection mechanism above has ejected the card sleeve and sends an electrical signal to the control unit 5. The control unit 5 can be implemented using a programmable logic controller, embedded control system, industrial computer, etc., and is electrically connected to the drive mechanism 3 and the detection device 4. After receiving the electrical signal from the detection device 4, it controls the drive mechanism 3 to drive the mounting base 2 to move. During the process of the mounting base 2 moving to the first position, the pusher 6 pushes the card sleeve that has fallen below the placement opening 12 away from the placement opening 12. At the same time, when the mounting base 2 is in the first position, it maintains a blocking state to prevent the fallen card sleeve from approaching the area below the placement opening 12, so that the discarded card sleeves below the placement opening 12 will not accumulate, thereby ensuring the stability of the automatic loading of new card sleeves.

[0022] In one embodiment, when the protective box is in operation, the synthesizer is mounted on the mounting base 2, which is in the second position. When the detection device 4 senses the upper synthesizer sleeve being pushed out, it sends an electrical signal to the control unit 5. The control unit 5 activates the drive mechanism 3, thereby driving the mounting base 2 to move backward to the first position exposing the placement port 12. During this process, the pusher 6 pushes the sleeve below the placement port 12 backward, thus clearing space below the placement port 12 for the discarded sleeve to fall. After the mounting base 2 reaches the first position, the pusher 6 restricts the pushed-back sleeve from approaching the area below the placement port 12, and the discarded sleeve falls. The sleeve retainer on the synthesizer retracts back to the installation position. After the detection device 4 senses the retraction, it sends an electrical signal to the control unit 5. The control unit 5 controls the drive mechanism 3 to drive the mounting base 2 forward to the second position covering the placement port 12, thereby completing one complete working cycle.

[0023] The control unit 5 controls the movement of the mounting base 2, causing the falling ferrule to fall into the receiving cavity 11. The pusher 6 then moves the discarded ferrule below the placement port 12 into the receiving cavity 11, ensuring that it does not accumulate in the loading path and thus affect the automatic loading of the next ferrule for multiple batches of synthesizers. At the same time, the control unit 5 controls the mounting base 2 to cover the placement port 12 after the ferrule falls into the receiving cavity 11, thereby reducing the radiation dose from the discarded ferrule received by the operator during the manual installation of new ferrules for a single batch of synthesizers.

[0024] The upper part of the pusher 6 is rotatably connected to the lower part of the mounting base 2, and a limiting member 7 is provided between the pusher 6 and the mounting base 2 to limit the rotation range of the pusher 6.

[0025] In one embodiment, when the mounting base 2 moves forward to the second position, the pushing member 6 moves forward with the mounting base 2. The limiting member 7 does not restrict the rearward rotation of the pushing member 6. At this time, if the pushing member 6 encounters a sleeve located below the placement opening 12, the sleeve will exert resistance on the pushing member 6, forcing the pushing member 6 to rotate rearward around the connection point with the mounting base 2 to avoid it. After avoiding the sleeve, the pushing member 6 continues to move forward with the mounting base 2 until it reaches the front side of the sleeve and disengages from the sleeve. When the mounting base 2 moves backward to the first position, the pushing member 6 moves backward with the mounting base 2. The limiting member 7 restricts the forward rotation of the pushing member 6. At this time, if the pushing member 6 encounters a sleeve located below the placement opening 12, the limiting member 7 restricts the forward rotation of the pushing member 6, causing the pushing member 6 to rigidly drive the sleeve to move backward together until the sleeve is away from below the placement opening 12. When the mounting base 2 is in the first position, the limiting member 7 restricts the forward rotation of the pushing member 6, thereby preventing the sleeve behind it from approaching below the placement opening 12. The flexibility and adaptability of the system are improved by the setting of the pusher 6, which is rotatably connected to the lower part of the mounting base 2, and the limiter 7.

[0026] The pusher 6 is a push rod, and there are two pushers 6, which are respectively arranged on the left and right sides of the receiving cavity 11.

[0027] Compared to the push plate, the contact points with the push rod sleeve are more concentrated, resulting in greater flexibility and lower frictional resistance, reducing the risk of jamming. The coordinated action of two push rods distributed on the left and right sides of the receiving cavity 11 ensures a more balanced pushing motion. Compared to a single push rod, this prevents the sleeve from tilting or jamming, improving the stability of pushing the discarded sleeve.

[0028] The limiting component 7 is a limiting block located at the lower part of the mounting base 2.

[0029] like Figure 4As shown in Embodiment 1, a rotating platform is fixedly connected to the lower part of the mounting base 2, and the pusher 6 is rotatably connected to the rotating platform. A limiting block is set on the front side of the pusher 6. When the mounting base 2 moves backward to the first position, the limiting block prevents the pusher 6 from rotating forward beyond a predetermined range, ensuring that the pusher can effectively push the sleeve below the placement port 12 away from the mounting path. By using the limiting block as the limiting element 7, the structure is simple, easy to manufacture and install, and has low maintenance costs.

[0030] The limiting member 7 is a limiting pull rope with one end connected to the mounting base 2 and the other end connected to the pushing member 6.

[0031] The limiting rope can be made of high-strength, flexible material. When the pusher 5 rotates to a set angle, the limiting rope is tightened, restricting its continued rotation and thus achieving the limiting function. Compared to rigid limiting structures, rope limiting has a certain degree of flexibility, reducing the risk of equipment damage.

[0032] like Figure 5 As shown in Embodiment 2, one end of the limiting pull rope is connected to the pusher 6, and the other end is connected to the mounting base 2 located on the rear side of the pusher 6. When the mounting base 2 moves backward to the first position, the pusher 6 is pressed by the ferrule and rotates forward. The limiting pull rope is tightened, restricting the pusher 6 from rotating further forward, ensuring that the pusher 6 can effectively push the ferrule below the placement port 12 away from the mounting path.

[0033] The drive mechanism 3 includes a piston cylinder 31 mounted on the housing 1, and the output end of the piston cylinder 31 is connected to the mounting base 2.

[0034] The piston cylinder 31 serves as a power source, and its piston rod is connected to the mounting base 2. Through the extension and retraction of the piston rod, the mounting base 2 is driven to switch between the first position and the second position.

[0035] The upper part of the housing 1 is provided with a slide rail 8 along the length of the housing 1, and the mounting base 2 is slidably connected to the slide rail 8.

[0036] The slide rail 8, which is set along the length of the housing 1, provides a stable linear motion path for the mounting base 2, so that the mounting base 2 can move along the length of the housing 1 under the action of the drive mechanism 3, and reduce the phenomenon of offset and shaking of the mounting base 2 during the movement.

[0037] The housing 1 and the mounting base 2 are made of lead.

[0038] The enclosure 1 and the mounting base 2 form a protective enclosure with sufficient lead shielding, which effectively blocks the radioactive rays released by the discarded card sleeves and reduces the radiation dose to the operators.
