Description

Technical Field

[0001] This utility model relates to the field of radiopharmaceutical dispensing equipment technology, and in particular to a radiopharmaceutical dispensing instrument for controlling waste liquid splashing. Background Technology

[0002] Radiopharmaceuticals are playing an increasingly important role in medical diagnosis and treatment. Traditional methods of dispensing radiopharmaceuticals mainly rely on manual operation, requiring medical staff to directly contact radioactive materials and be exposed to radiation for extended periods, posing a serious threat to their health. Long hours of work can also lead to fatigue, lack of concentration, and errors that could result in radiation safety accidents. Furthermore, manual dispensing is inefficient and cannot meet the modern medical demand for rapid and large-scale supply of radiopharmaceuticals.

[0003] To address this issue, fully automated radiopharmaceutical dispensing systems have been introduced to the market. These systems automatically dispense radiopharmaceutical solutions into syringes and typically include waste bottles for collecting radioactive waste. Once full, these bottles need to be removed for cleaning or replaced with new ones, and are therefore usually located externally to the dispensing system. However, because the waste bottle openings are equipped with venting pipes to expel excess gas, waste may splash into the heated chamber along with the gas when the waste is discharged. This splashing problem worsens as the amount of waste in the bottle increases. This poses a safety risk of accidental contact with splashed waste when medical personnel handle the dispensed syringes. Utility Model Content

[0020] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model. Example

[0021] This embodiment provides a radiopharmaceutical dispensing device for controlling waste liquid splashing, including a housing, a protective bracket, and a retraction device.

[0022] Please refer to Figure 1 , 2 The outer casing 10 serves as the external frame and cover structure of the dispensing device. Its side walls have notches 11, and protective supports are installed at these notches 11. The protective supports extend inwards from the outer casing 10 and include two side plates 21, a bottom plate 22, and a back plate 23 positioned between the two side plates 21. The bottom plate, back plate, and two side plates form a space with openings at the top and sides, and the side openings correspond to the notches 11. The height of the side plates 21 is significantly higher than that of the waste liquid bottle 50.

[0023] The retraction device is located between the two side plates 21 and includes a base 31 mounted on the bottom plate 22. The base 31 has a guide rail 32 parallel to the side plates 21, and a slider 33 is slidably connected to the guide rail 32. The slider 33 has a platform 34 equipped with an anti-tipping device. The waste liquid bottle 50 is placed on the platform 34, and the anti-tipping device enhances stability. When the dispensing device is working normally, the sliding platform 34 can retract the waste liquid bottle 50 into the protective support, preventing waste liquid from splashing into the protective support and avoiding contamination of the hot chamber, thus eliminating safety risks. When the waste liquid bottle is full, it can be pulled out for easy replacement. Since the half-life of radiopharmaceuticals is generally short, splashed liquid inside the protective support does not need to be treated.

[0024] In this embodiment, the anti-tipping device includes a vertical plate 35 disposed on the platform 34 and a U-shaped ring 36 disposed on the top of the vertical plate 35; in other embodiments, the anti-tipping device may be a placement groove disposed on the platform 34. Example

[0025] This embodiment provides a radiopharmaceutical dispensing device for controlling waste liquid splashing. Based on Embodiment 1, the base 31 is provided with two guide rails 32, and the stage 34 is provided with a slider 33 slidably connected to the two guide rails 32. The base 31 is also provided with a motor 37, the output shaft of which is provided with a lead screw, which is threadedly connected to the slider 33. The motor 37 drives the stage 34 to slide via the lead screw. A weighing device 40 is also provided between the base 31 and the base plate 22 to monitor the weight change of the waste liquid bottle. The motor 37 and the weighing device 40 are both electrically connected to the dispensing device's control system. When the control system detects that the weight increase in the waste liquid bottle is close to a preset value, it stops the next dispensing operation and, after the current dispensing is completed, starts the motor 37 to push the waste liquid bottle out of the dispensing device.

[0026] Furthermore, the base 31 is provided with a lower panel 38, and the two side panels 21 are rotatably connected to an upper panel 39 to close the side opening of the protective bracket and improve the appearance of the equipment. The vertical plate 35 is provided with an extension plate 351, and a connecting rod 391 is hinged between the upper panel 39 and the extension plate 351. When the platform 34 is retracted into the protective bracket, the upper panel 39 closes the side opening; when the platform 34 is extended, the connecting rod 391 opens the upper panel 39. Figure 3 As shown. The upper panel 39 and the extension plate 351 also provide protection against splashed waste liquid. The upper panel 39 is also provided with a through hole 392, which allows the waste liquid discharge pipe to extend into and connect to the waste liquid bottle 50. The through hole 392 can be an oval hole. Preferably, the length of the upper panel is 1 / 2 of the height of the side opening, which can extend to the bottom of the waste liquid bottle opening, providing protection and reducing the space occupied when opened.

[0027] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
