Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, and in particular to an automated injection device for radiopharmaceuticals and contrast agents that is compatible with high magnetic field environments. Background Technology

[0002] Nuclear medicine is an emerging discipline that uses nuclear technology to diagnose, treat, and study diseases. It is a product of the integration of modern science and technology, including nuclear technology, electronic technology, computer technology, chemistry, physics, and biology, with medicine. Nuclear medicine can be divided into clinical nuclear medicine and experimental nuclear medicine. The radiopharmaceuticals used in nuclear medicine are employed to obtain images or functional parameters of target organs or diseased tissues in the body for disease diagnosis; furthermore, radiopharmaceuticals can be used to understand their biodistribution and pharmacokinetics in vivo.

[0003] The commonly used method for injecting radiopharmaceuticals in nuclear medicine is manual dispensing of radiopharmaceuticals and manual injection into the patient's vein. For contrast-enhanced CT or MRI imaging, the commonly used method is to inject the corresponding contrast agent using an automated high-pressure injector. With the increasing number of nuclear medicine PET / CT and PET / MR equipment installed in China and the rapid development of radiopharmaceutical research, the growth in clinical applications and research in nuclear medicine has led to a corresponding increase in radiation exposure for medical personnel due to the dispensing and injection of radiopharmaceuticals, increasing the possibility of uncertain injuries. Furthermore, for patients requiring simultaneous CT or MRI contrast-enhanced CT, separate injections are necessary, increasing workload and requiring two intravenous punctures. To reduce radiation exposure and workload for medical personnel and minimize injuries from multiple intravenous punctures, this technology provides an automated radiopharmaceutical and contrast agent injection device compatible with high magnetic field environments. Summary of the Invention

[0008] Furthermore, the adjustment panel includes a single adjustment panel, a double adjustment panel, and a full adjustment panel. The full adjustment panel is disposed on the adjustment plate, the double adjustment panel is disposed on the full adjustment panel, and the single adjustment panel is disposed on the side end of the double adjustment panel.

[0009] Furthermore, the extraction and injection device includes a radiopharmaceutical injection assembly, a medical saline injection assembly, and a contrast agent injection assembly. The radiopharmaceutical injection assembly, the medical saline injection assembly, and the contrast agent injection assembly have the same structure. A fixed frame is provided at the top of the lower chamber. The radiopharmaceutical injection assembly, the medical saline injection assembly, and the contrast agent injection assembly are arranged sequentially on the fixed frame, and their upper ends all pass through the top of the lower chamber and are located in the upper chamber. The radiopharmaceutical injection assembly, the medical saline injection assembly, and the contrast agent injection assembly are respectively mounted on corresponding drug delivery devices.

[0010] Furthermore, the radiopharmaceutical injection assembly includes an injection block, a syringe, an extraction tube, an extraction needle, an electrically operated three-way ball valve, and an injection tube. The upper end of the syringe is located in the upper chamber and is connected to the mounting bracket at a slightly upper-middle position. The upper end of the injection tube is sleeved on the lower end of the syringe and is connected. One end of the extraction tube is connected to the injection tube, and the other end passes through the outside of the lower chamber and is located inside the lower chamber. The electrically operated three-way ball valve is located at the connection between the extraction tube and the injection tube. The extraction needle is connected to the extraction tube, and the extraction end of the extraction needle is positioned downwards. The injection block is located at the upper end of the syringe, and the injection block has a groove.

[0011] Furthermore, it also includes a four-way connecting pipe and a fixing block. There are two fixing blocks, which are symmetrically arranged on the outer side wall of the lower chamber. The four-way connecting pipe is arranged on the two fixing blocks. The injection pipes on the radiopharmaceutical injection assembly, the medical saline injection assembly, and the contrast agent injection assembly are respectively connected to the four-way connecting pipe. The lower end of the four-way connecting pipe is used to connect to the required matching liquid injection needle.

[0012] Furthermore, each of the aforementioned drug delivery devices includes a drug delivery frame, a drug delivery hydraulic cylinder, a drug delivery block, and a drug delivery plate. The lower chamber is divided into a left inner cavity and a right inner cavity. The drug delivery frame is disposed on the inner wall of the left inner cavity of the lower chamber, and the display screen is located in the right inner cavity of the lower chamber. The drug delivery hydraulic cylinder is disposed on the drug delivery frame, and the drug delivery block is disposed above the drug delivery frame. The output end of the drug delivery hydraulic cylinder passes through the drug delivery block and is in a sliding fit. The drug delivery plate is disposed on the output end of the drug delivery hydraulic cylinder. The drug delivery plate is provided with a storage slot, and the storage slot is aligned with the corresponding extraction needle on the same vertical axis. The storage slots on the corresponding drug delivery plates in the aforementioned drug delivery devices are matched with the corresponding drugs. Each of the aforementioned drug delivery devices is equipped with a control system that can be operated via the display screen.

[0013] Furthermore, the radiopharmaceutical injection assembly and its corresponding drug delivery device are equipped with a lead glass device, which is a lead glass protective cover.

[0014] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: Firstly, when administering medication to a patient, this device can extract the required medications in precise quantities according to the patient's specific condition. After the required medications are extracted, the device can administer single injections, injections of any two medications, or simultaneous injections of three medications. This eliminates the need for patients to undergo two intravenous punctures during the medication administration process, reducing the damage caused by multiple intravenous punctures and also lowering the workload of medical staff.

[0015] Secondly, when performing quantitative extraction of radiopharmaceuticals, this device first opens the lead glass protective cover, places the lead container containing the radiopharmaceutical to be injected into the storage slot on the corresponding drug delivery plate, then opens the lead container and immediately closes the lead glass protective cover. Then, following the above steps, the radiopharmaceutical inside the lead container is quantitatively extracted and injected. This minimizes the radiation dose to medical personnel during the extraction and injection of radiopharmaceuticals and prevents environmental pollution.

[0016] Thirdly, when the extraction needle is inserted into the desired extraction position, the corresponding drug delivery hydraulic cylinder stops operating. At this time, the adjusting motor drives the adjusting screw on the output end of the adjusting motor to rotate, thereby moving the single adjusting panel on the adjusting panel to the groove on the corresponding injection block. Then, the drive motor drives the drive screw on the output end of the drive motor to rotate, which in turn drives the drive plate to move upward. The upward movement of the drive plate drives the adjusting device to move upward, thus enabling the single adjusting panel to move the corresponding injection block upward. Based on the drug injection dosage set on the display screen, the distance the drive motor moves the corresponding injection block upward is controlled. Simultaneously, the upward movement of the corresponding injection block drives the pull-out piston rod on the syringe to move upward, thereby extracting the drug through the extraction needle into the corresponding syringe. At this time, the electric three-way ball valve on the corresponding injection pipeline is in a state of opening and connecting the extraction pipeline and the injection pipeline, while the corresponding injection pipeline and the four-way connecting pipeline are closed and sealed, thus realizing the quantitative extraction of the drug.

[0017] Fourth, all materials in this device are non-magnetic (such as silicon, aluminum, copper, etc.), which enables the device to operate normally in the routine environment of nuclear medicine (such as PET / CT environment) and (PET / MR environment). Attached Figure Description

It includes a mobile device 1 and a display screen 11, as well as a base support 12, a drive device 2, a multi-functional adjustment device 3, an injection extraction device 4, and a drug delivery device 6. The mobile device 1 is horizontally positioned on the ground. The base support 12 is located at the upper end of the mobile device 1 and is divided into an upper chamber 121 and a lower chamber 122. The drive device 2 is located inside the upper chamber 121. The multi-functional adjustment device 3 is located at the output end of the drive device 2 and inside the upper chamber 121.

When administering medication to a patient, this device can precisely extract the required medications one by one according to the patient's specific condition. After extraction, the device can administer individual injections, injections of any two medications, or simultaneous injections of all three medications. This eliminates the need for double venipuncture during medication administration, reducing the risk of injury from multiple venipunctures and lowering the workload for medical staff. All materials used in this device are non-magnetic (such as silicon, aluminum, and copper), and the device complies with IEC standards. The IEC 62333-1 standard specifies the electromagnetic compatibility requirements for PET / CT equipment. This standard, officially titled "Electromagnetic Compatibility Assessment and Certification Procedures - Part 1: General Requirements," is an international standard developed by the International Electrotechnical Commission (IEC). It aims to provide assessment and certification procedures for various types of electromagnetic compatibility (EMC) products, enabling the device to operate normally in routine nuclear medicine environments (such as PET / CT environments) and PET / MR environments.

[0024] Preferably, the driving device 2 includes a drive motor 21, a drive frame 22, a drive screw 23, drive rods 24, and a drive plate 25. The drive motor 21 is disposed inside the upper chamber 121, and the drive frame 22 is disposed inside the upper chamber 121 and above the drive motor 21. The drive screw 23 is disposed on the output end of the drive motor 21, and its upper end passes through the drive frame 22 for rotatable connection. There are two drive rods 24, which are symmetrically arranged on the drive frame 22. The two ends of the drive plate 25 are sleeved on the two drive rods 24 and are in a sliding fit. The middle position of drive screw 25 is threaded onto drive screw 23. The drive device 2 is equipped with a control system and can be operated via display screen 11. The multi-functional adjustment device 3 includes an adjustment frame 31, an adjustment plate 32, an adjustment rod 33, an adjustment motor 34, an adjustment screw 35, and an adjustment panel 36. The adjustment frame 31 is mounted on drive plate 25. There are two adjustment rods 33, with their ends respectively mounted on the adjustment frame 31. The adjustment motor 34 is mounted on the adjustment frame 31. The adjustment screw 35 is mounted on the output end of the adjustment motor 34. The adjustment plate 32 is fitted onto the adjustment screw 35. The upper part is threaded, and the two ends of the adjusting plate 32 are respectively sleeved on the two adjusting rods 33, both of which are in a left-right sliding fit. The adjusting panel 36 is disposed on the adjusting plate 32. The multi-functional adjusting device 3 is equipped with a control system and can be operated through the display screen 11. The adjusting panel 36 includes a single adjusting panel 361, a double adjusting panel 362, and a full adjusting panel 363. The full adjusting panel 363 is disposed on the adjusting plate 32, the double adjusting panel 362 is disposed on the full adjusting panel 363, and the single adjusting panel 361 is disposed on the side end of the double adjusting panel 362. The extraction and injection device 4 includes radiopharmaceuticals. The radiopharmaceutical injection assembly 41, the saline injection assembly 42, and the contrast agent injection assembly 43 are identical in structure. A fixing frame 123 is provided at the top of the lower chamber 122. The radiopharmaceutical injection assembly 41, the saline injection assembly 42, and the contrast agent injection assembly 43 are arranged sequentially on the fixing frame 123, and their upper ends all pass through the top of the lower chamber 122 and are located in the upper chamber 121. The radiopharmaceutical injection assembly 41, the saline injection assembly 42, and the contrast agent injection assembly 43 are respectively mounted on the corresponding drug delivery device 6. When administering medical saline, contrast agents, and radiopharmaceuticals to patients, medical staff can set the required medication, injection method, and dosage on the display screen 11. Then, the lower end of the four-way connecting pipe 5 is connected to the matching liquid injection needle. The liquid injection needle is then inserted into the desired injection position on the patient. Finally, the required medication is placed in the storage slot 641 on the corresponding medication delivery plate 64 to perform the medication extraction and injection operation. When it is necessary to perform individual or separate drug extraction and injection of medical saline, contrast agents, and radiopharmaceuticals, the required drug is first placed on the storage slot 641 on the corresponding drug delivery plate 64, ensuring that the drug and the corresponding extraction needle 415 are matched and the drug opening faces the extraction needle 415. Then, the corresponding drug delivery hydraulic cylinder 62 drives the drug on the drug delivery plate 64 at its output end to move towards the corresponding extraction needle 415, at which point the extraction needle 415 is inserted into the drug. Once the extraction needle 415 is inserted to the desired extraction position, the corresponding drug delivery hydraulic cylinder 62 stops operating. At this time, the adjusting motor 34 drives the adjusting screw 35 at its output end to rotate, thereby moving the single adjusting panel 361 on the adjusting panel 36 on the adjusting screw 35 to the groove 412 on the corresponding injection block 411 (see reference). Figure 10 Then, the drive motor 21 drives the drive screw 23 at its output end to rotate. The rotation of the drive screw 23 drives the drive plate 25 to move upward. The upward movement of the drive plate 25 drives the adjustment device to move upward, thereby enabling the corresponding injection block 411 to move upward via the single adjustment panel 361. Based on the drug injection dosage set on the display screen 11, the distance by which the drive motor 21 drives the corresponding injection block 411 to move upward is controlled. Simultaneously, the upward movement of the corresponding injection block 411 drives the pull-out piston rod on the syringe 413 to move upward, thereby drawing the drug through the extraction needle 415 into the corresponding syringe 413. At this time, the electric three-way ball valve 416 on the corresponding injection tubing 417 is in the position of connecting the extraction tubing 414 and the injection... The injection tube 417 is opened to the connected state, while the corresponding injection tube 417 and the four-way connecting tube 5 are closed to the sealed state, thereby realizing the quantitative extraction of drugs. After the required quantitative extraction of drugs is completed, the required extraction tube 414 and the corresponding injection tube 417 are closed to the sealed state by the electric three-way ball valve 416, while the corresponding injection tube 417 and the four-way connecting tube 5 are opened to the connected state. At the same time, the drive motor 21 runs and drives the corresponding injection block 411 to move downward, so that the pull-out piston rod on the corresponding syringe 413 moves downward, and the drugs inside the syringe 413 flow into the four-way connecting tube 5 through the injection tube 417, and are introduced into the required position of the patient through the liquid injection needle tube connected to the four-way connecting tube 5 for treatment. When simultaneous injection of any two of the following drugs—medical saline, contrast agent, and radiopharmaceutical—is required, after the drugs are quantitatively extracted one by one according to the above steps, if medical saline and contrast agent are to be injected simultaneously, the single adjustment panel 361 is moved by the operation of the adjusting motor 34 to disengage from the groove 412 on the corresponding injection block 411 and return to its original position. Then, the driving motor 21 moves the adjusting device upward, so that the height of the full adjustment panel 363 is higher than the corresponding injection block 411 that has been stretched and extracted. The driving motor 21 then stops. Finally, the adjusting motor 34 moves the full adjustment panel 363 toward the desired syringe 413 (see reference). Figure 11 When the fully adjustable panel 363 is positioned above the corresponding injection block 411 in the medical saline injection assembly 42 and the contrast agent injection assembly 43, the electric three-way ball valve 416 closes the required extraction pipe 414 and the corresponding injection pipe 417 to a sealed state, while the corresponding injection pipe 417 is opened to the four-way connecting pipe 5 to be in a connected state. At the same time, the drive motor 21 drives the fully adjustable panel 363 in the adjusting device to move downward, pushing the corresponding injection block 411 downward, thereby dispensing the medical saline injection assembly 42 and the contrast agent injection assembly 43. The medication inside the syringe 413 in the injection assembly 43 flows into the four-way connecting pipe 5 through the injection tube 417, and is then delivered to the patient's desired location for treatment via the liquid injection needle connected to the four-way connecting pipe 5. If medical saline and radiopharmaceuticals are injected simultaneously, after the medications are quantitatively extracted one by one according to the above steps, the dual adjustment panel 362 is positioned above the corresponding injection blocks 411 in the medical saline injection assembly 42 and the radiopharmaceutical injection assembly 41 by adjusting the operation of the motor 34 and cooperating with the drive motor 21 (see reference). Figure 12 The dual adjustment panel 362 is used to push downwards, thereby simultaneously injecting medical saline and radiopharmaceuticals. If radiopharmaceuticals and contrast agents are injected simultaneously, after the drugs are quantitatively extracted one by one according to the above steps, the adjustment motor 34 and drive motor 21 work together to position the full adjustment panel 363 above the corresponding injection blocks 411 in the contrast agent injection assembly 43 and the radiopharmaceutical injection assembly 41 (refer to...). Figure 9 The contrast agent and radiopharmaceutical are injected simultaneously by pushing the full adjustment panel 363 downwards. When simultaneous injection of medical saline, contrast agents, and radiopharmaceuticals is required, after the drugs are quantitatively extracted one by one according to the above steps, the adjustment panel 363 is positioned above the corresponding injection blocks 411 in the contrast agent injection assembly 43 and the radiopharmaceutical injection assembly 41 by adjusting the operation of motor 34 and cooperating with drive motor 21 (see reference). Figure 13 The adjustment panel 363 is pushed downwards to simultaneously inject medical saline, contrast agent, and radiopharmaceutical.

The syringe 411 is positioned above the syringe 413 and has a groove 412 on it. When performing quantitative extraction of radiopharmaceuticals, the lead glass protective cover is first opened, and the lead container containing the radiopharmaceutical to be injected is placed into the storage slot 641 on the corresponding drug delivery plate 64. Then, the lead container is opened and the lead glass protective cover is immediately closed. Then, the radiopharmaceutical inside the lead container is quantitatively extracted according to the above steps and injected. In this way, the radiation dose of radiopharmaceuticals to medical personnel is minimized during the extraction and injection of radiopharmaceuticals, and environmental pollution is prevented.
