DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with 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 protection scope of the present invention.

[0024] like Figure 1 The figure shows a 53-way infusion connecting pipe assembly described in this embodiment, which is arranged in a device with a radiation protection function to realize the transfer, dilution, injection and other operations of radioactive drugs. The above-mentioned 53-way infusion connecting pipe 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-exhausting liquid 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, a puncture device 34 and other components or components. Among them, the above-mentioned 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, and all have three ports formed by a connecting port. The above-mentioned five groups of three-way valves can be electric three-way valves or manual three-way valves. By switching and regulating each group of three-way valves, one of the ports of the three-way valve is closed and the other two ports are connected.

[0025] Among them, the first end of the first three-way valve 11 is connected to the first end of the second three-way valve 12, and one end of the first puncture needle 21 is connected to the second end of the first three-way valve 11 through a conical joint 6, so that the first puncture needle 21 can be disassembled and replaced. One end of the first syringe 31 is connected to the third end of the first three-way valve 11 through a conical joint 6, so that the first syringe 31 can 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 through a conical joint 6, so that the second puncture needle 22 can be disassembled and replaced. The first end of the infusion main tube 7 is connected to the third end of the second three-way valve 12. The self-exhausting liquid medicine filter 4 is a conventional component of the prior art and has an exhaust function. The self-exhausting liquid medicine filter 4 has two ports, so that liquid can enter through one port and be discharged from the other port. The first end of the self-exhausting liquid medicine filter 4 is connected to the second end of the infusion main tube 7 through a conical joint 6, so that the self-exhausting liquid medicine filter 4 can 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 and has two ports. The first end of the first extension tube 51 is plug-connected to the second end of the self-exhausting liquid medicine filter 4 through a conical joint 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 a conical joint 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 joint 6 on the second extension tube 52 can be connected to an ordinary intravenous needle or an indwelling needle to form a complete passage for the liquid medicine to enter the human 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 through the first end and the second end respectively. One end of the second syringe 32 is plugged and connected to the third end of the third three-way valve 13 through the conical joint 6, so that the second syringe 32 can be disassembled and replaced. One end of the third syringe 33 is plugged and connected to the third end of the fourth three-way valve 14 through the conical joint 6, so that the third syringe 33 can be disassembled and replaced. One end of the puncture device 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 are all conventional components in 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 , which is one of the arrangement sequences, that is, the fourth three-way valve 14 is arranged between the third three-way valve 13 and the fifth three-way valve 15 .

[0030] Specific steps:

[0031] a. Closing the first end of the first three-way valve 11 allows the first syringe 31 to extract high-concentration radioactive drugs through the pipeline 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 radioactive drugs in the tungsten steel container to the intermediate container through the pipeline and the second puncture needle 22 for concentration detection and dilution.

[0032] b. 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, so that the second syringe 32 can extract the diluent from the infusion bag through the infusion main tube 7 and the puncture device 34. Close the second end on the left side of the third three-way valve 13 and close the first end of the second three-way valve 12, so that the second syringe 32 can transfer the diluent to the intermediate container through the pipeline and the second puncture needle 22 for dilution.

[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 extract the diluted radioactive drug in the intermediate container through the infusion main 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, so that the second syringe 32 can extract the diluent in the infusion bag through the infusion main tube 7 and the puncture device 34 for flushing the residual drug in the pipeline after the subsequent radioactive drug injection.

[0035] e. Close 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, so that the medicine in the third syringe 33 can be injected into the human body. The medicine first passes through the self-exhausting liquid medicine filter 4 to remove the air mixed in the medicine extraction process, and then passes through the first extension tube 51, the second extension tube 52, and the one-way valve 5 in sequence to enter the extension tube 51, and finally enter the human body. After the injection is stopped, the one-way valve 5 is reversely closed due to the blood pressure of the human body, so that the physical barrier of the pipelines before and after the one-way valve 5 is realized to avoid cross contamination.

[0036] f. 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 third end of the fifth three-way valve 15, so that the diluent in the second syringe 32 can be injected into the human body to flush the pipeline, thereby achieving complete injection of the drug in the pipeline and reducing drug residue.

[0037] g. After the complete injection process is completed, the first extension tube 51 is disassembled from the self-exhaust liquid medicine filter 4, and the first extension tube 51, the one-way valve 5, and the second extension tube 52 are replaced, and then injection is performed again. Among them, the self-exhaust liquid medicine filter 4 usually does not need to be disassembled and replaced after injection. If the particle interception amount reaches its threshold after multiple uses, causing abnormal pressure of the equipment, it can be replaced.

[0038] In the above manner, by switching each group of three-way valves to different connection states, the transfer and dilution of radioactive drugs can be realized in the equipment with radiation protection function, the injection of radioactive drugs can be realized, and the residual drugs in the entire infusion pipeline can be flushed, effectively reducing the radioactive hazards of radioactive drugs to medical staff. A new round of injection can be performed after replacing the one-way valve 5, the first extension tube 51, and the second extension tube 52, so as to meet the injection of radioactive drugs for multiple people without replacing the entire set of infusion pipelines, effectively reducing economic costs, and having strong practicality.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
