[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0024] like Figure 1 The diagram shows a 53-way infusion connection tubing assembly as described in this embodiment. This 53-way infusion connection tubing assembly is arranged within a device with radiation protection to facilitate the transfer, dilution, and injection of radiopharmaceuticals. The aforementioned 53-way infusion connection tubing assembly includes a first three-way valve 11, a second three-way valve 12, a third three-way valve 13, a fourth three-way valve 14, a fifth three-way valve 15, an infusion main pipe 7, a self-venting drug solution filter 4, an infusion replacement assembly, a first puncture needle 21, a first syringe 31, a second insertion needle, a second syringe 32, a third syringe 33, and a puncture device 34, among other components. The first three-way valve 11, the second three-way valve 12, the third three-way valve 13, the fourth three-way valve 14, and the fifth three-way valve 15 are all conventional components of the prior art, each having three ports formed by a connecting opening. These five sets of three-way valves can be electric or manual three-way valves. By switching and adjusting each set of three-way valves, one port of the three-way valve is closed, while the other two ports are connected.

[0025] The first end of the first three-way valve 11 is connected to the first end of the second three-way valve 12. One end of the first puncture needle 21 is connected to the second end of the first three-way valve 11 via a conical connector 6, allowing the first puncture needle 21 to be disassembled and replaced. One end of the first syringe 31 is connected to the third end of the first three-way valve 11 via a conical connector 6, allowing the first syringe 31 to be disassembled and replaced. One end of the second puncture needle 22 is connected to the second end of the second three-way valve 12 via a conical connector 6, allowing the second puncture needle 22 to be disassembled and replaced. The first end of the infusion main pipe 7 is connected to the third end of the second three-way valve 12. The self-venting drug filter 4 is a conventional component of the prior art and has a venting function. The self-venting drug filter 4 has two ports, allowing liquid to enter through one port and exit from the other port. The first end of the self-venting drug filter 4 is connected to the second end of the infusion main pipe 7 via a conical connector 6, allowing the self-venting drug filter 4 to be disassembled.

[0026] The aforementioned infusion replacement assembly includes a one-way valve 5, a first extension tube 51, and a second extension tube 52. The one-way valve 5 is a conventional component of the prior art, having two ports. The first end of the first extension tube 51 is connected to the second end of the self-venting drug filter 4 via a conical connector 6, and the second end is connected to the first end of the one-way valve 5. The first end of the second extension tube 52 is connected to the second end of the one-way valve 5, and the conical connector 6 is fixed to the second end. By disassembling the first end of the first extension tube 51, the one-way valve 5, the first extension tube 51, and the second extension tube 52 can be disassembled and replaced as a whole. The conical connector 6 on the second extension tube 52 can be connected to a standard intravenous needle or indwelling needle to form a complete pathway for drug delivery into the body.

[0027] The aforementioned third three-way valve 13, fourth three-way valve 14, and fifth three-way valve 15 are connected in series to the infusion main pipe 7 via their first and second ends, respectively. One end of the second syringe 32 is connected to the third end of the third three-way valve 13 via a conical connector 6, allowing the second syringe 32 to be disassembled and replaced. One end of the third syringe 33 is connected to the third end of the fourth three-way valve 14 via a conical connector 6, allowing the third syringe 33 to be disassembled and replaced. One end of the trocar 34 is connected to the third end of the fifth three-way valve 15.

[0028] The first puncture needle 21, the first syringe 31, the second puncture needle 22, the second syringe 32, the third syringe 33, and the inserter mentioned above are all conventional components of the prior art, and their specific functions are common knowledge.

[0029] It should be noted that the aforementioned conical joints 6 are conventional components of the prior art, and their specific structures and functions are common knowledge. In this embodiment, the arrangement order of the aforementioned third three-way valve 13, fourth three-way valve 14, and fifth three-way valve 15 on the infusion main pipe 7 can be adjusted according to the actual design. Figure 1 One possible arrangement is that the fourth three-way valve 14 is positioned between the third three-way valve 13 and the fifth three-way valve 15.

[0030] Specific usage steps:

[0031] a. Closing the first end of the first three-way valve 11 allows the first syringe 31 to draw a high concentration of radiopharmaceutical through the tubing and the first puncture needle 21. Closing the second end of the first three-way valve 11 and the third end of the second three-way valve 12 allows the first syringe 31 to transfer the high concentration of radiopharmaceutical from the tungsten steel container to the intermediate container for concentration detection and dilution through the tubing and the second puncture needle 22.

[0032] b. Closing the first end on the right side of the third three-way valve 13, closing the third end of the fourth three-way valve 14, and closing the second end on the left side of the fifth three-way valve 15 allows the second syringe 32 to draw diluent from the infusion bag through the infusion main tube 7 and the puncture device 34. Closing the second end on the left side of the third three-way valve 13 and closing the first end of the second three-way valve 12 allows the second syringe 32 to transfer the diluent to the intermediate container for dilution through the tubing and the second puncture needle 22.

[0033] c. Close the first end of the second three-way valve 12, close the third end of the third single-way valve, and close the second end on the left side of the fourth three-way valve 14, so that the third syringe 33 can draw the diluted radiopharmaceutical from the intermediate container through the infusion tube 7 and the second puncture needle 22.

[0034] d. Close the first end on the right side of the third three-way valve 13, close the third end of the fourth three-way valve 14, and close the second end on the left side of the fifth three-way valve 15. This allows the second syringe 32 to draw diluent from the infusion bag through the infusion main tube 7 and the puncture device 34 for flushing of residual drugs in the tubing after subsequent radiopharmaceutical injection.

[0035] e. Closing the first end on the right side of the fourth three-way valve 14 and the third end of the fifth three-way valve 15 allows the medication in the third syringe 33 to be injected into the human body. The medication first passes through the self-venting medication filter 4 to remove air mixed in during the medication extraction process, then sequentially passes through the first extension tube 51, the second extension tube 52, and the one-way valve 5 before entering the extension tube 51 and finally entering the human body. After the injection stops, the one-way valve 5 closes in reverse due to the body's blood pressure, achieving physical isolation between the tubing before and after the one-way valve 5 and preventing cross-contamination.

[0036] f. By closing the first end on the right side of the third three-way valve 13, closing the third end of the fourth three-way valve 14, and closing the third end of the fifth three-way valve 15, the diluent in the second syringe 32 can be injected into the human body to flush the tubing, achieve complete injection of the drug in the tubing, and reduce drug residue.

[0037] g. After completing the entire injection process, remove the first extension tube 51 from the self-venting liquid filter 4 to replace the first extension tube 51, the one-way valve 5, and the second extension tube 52, and then inject again. The self-venting liquid filter 4 usually does not need to be disassembled or replaced after injection. However, if its particulate interception level reaches its threshold after repeated use, causing abnormal equipment pressure, it can be replaced.

[0038] In the above method, by switching the three-way valves of each group to different connection states, radiopharmaceuticals can be transferred and diluted, injected, and residual drugs flushed from the entire infusion line within equipment with radiation protection functions, effectively reducing the radiation hazards to medical personnel. A new round of injections can be performed after replacing the one-way valve 5, the first extension tube 51, and the second extension tube 52, thus meeting the needs of multiple radiopharmaceutical injections without replacing the entire infusion line, effectively reducing economic costs and demonstrating strong practicality.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
