[0052] As shown in Figures 1 to 4, the trocar injection line system 1 of this embodiment includes an injection line 10, multiple first trocars 11, a first aspiration line 12, a second trocar 13, and a second aspiration line 14. The injection line 10 has a first inlet connector 101, a second inlet connector 102, and an infusion connector 103. The first inlet connector 101 is connected to the infusion connector 103 via a pipeline, and the second inlet connector 102 is connected to the infusion connector 103 via a pipeline. The infusion connector 103 can be connected to the patient end. Two adjacent first trocars 11 are connected via a first serial connection line 15, connecting the first trocars 11 in series so that the first trocars 11 are connected sequentially in the direction A of the liquid medicine flow. In the direction of the liquid medicine flow, one first trocar 11 is closest to the first aspiration line 12, and the other first trocar 11 is farthest from the first aspiration line 12. The first pipette line 12 has two opposite ends, one end of which is connected to the first puncture device 11 closest to the first pipette line, and the other end of which is connected to the first liquid inlet connector 101. The second pipette line 14 has two opposite ends, one end of which is connected to the second puncture device 13, and the other end of which is connected to the second liquid inlet connector 102.

[0053] Both the first puncture device 11 and the second puncture device 13 have a puncturing tip, which can be sharp and capable of piercing the stopper of a stoppered container. During use, each first puncture device 11 is connected to the corresponding first container 6, and the second puncture device 13 is connected to the corresponding second container 7. The first inlet connector 101 can be connected to the first syringe 4, and the second inlet connector 102 can be connected to the second syringe 5. When the first syringe 4 is in operation, it can draw liquid from the first container 6 via the first aspiration line 12 and inject the first liquid through the injection line 10. When the second syringe 5 is in operation, it can draw liquid from the second container 7 via the second aspiration line 14 and inject the second liquid through the injection line 10. The first and second liquids can be different; for example, the first liquid can be a contrast agent and the second liquid can be saline. Of course, the second liquid can also be other liquids compatible with contrast agents.

[0054] Since multiple first puncture devices 11 are provided, each first puncture device 11 can be connected to a first liquid medicine container 6 by puncture, so that the puncture device injection pipeline system 1 can be connected to multiple first liquid medicine containers 6 at the same time. The first liquid medicine containers 6 are arranged in series through the first puncture devices 11. Therefore, while ensuring that at least one first liquid medicine container 6 can normally provide liquid medicine, other first liquid medicine containers 6 can be replaced, thereby improving the injection efficiency of liquid medicine.

[0055] For this injection line system, there can be only one group of first liquid medicine containers 6, corresponding to one first liquid pipetting line 12. There can be multiple groups of first liquid medicine containers 6, corresponding to multiple first liquid pipetting lines 12, each of which is connected to the injection line 10. There can be only one group of second liquid medicine containers 7, corresponding to one second liquid pipetting line 14. There can be multiple groups of second liquid medicine containers 7, corresponding to multiple second liquid pipetting lines 14, each of which is connected to the injection line 10.

[0056] In some embodiments, the first liquid suction line 12 is provided with a first controller 121 for controlling the on / off operation of the line. When the first controller 121 is turned on, the first liquid suction line 12 is connected; when the first controller 121 is turned off, the first liquid suction line 12 is disconnected. The first series line 15 is provided with a second controller 151 for controlling the on / off operation of the line. When the second controller 151 is turned on, the first series line 15 is connected; when the second controller 151 is turned off, the first series line 15 is disconnected.

[0057] When the first controller 121 is turned on and the second controller 151 is turned off, the liquid in the first liquid container 6 closest to the first liquid aspiration line 12 can flow through the first liquid aspiration line 12 to the first syringe 4. When both the first controller 121 and the second controller 151 are turned on, the first puncture devices 11 are connected sequentially, and the first liquid in the subsequent first liquid container 6 flows into the preceding first liquid container 6 in the liquid aspiration direction A.

[0058] In some embodiments, there may be two first puncture devices 11, corresponding to two first liquid medicine containers 6. The two first puncture devices 11 are each connected to the corresponding first liquid medicine container 6 through a puncture. Referring to Figure 1, the first liquid medicine container 6 located on the left and closer to the first syringe 4 can eliminate bubbles in the first liquid medicine container 6 located on the right and farther from the first syringe 4. The liquid medicine in the left first liquid medicine container 6 can serve as a safety reserve. The two first puncture devices 11 are connected by a first serial conduit 15, and one of the first puncture devices 11 is directly connected to the end of the first pipette 12. The diameter of the liquid inlet of the first puncture device 11 farther from the first pipette 12 can be greater than or equal to the diameter of the liquid inlet of the first puncture device 11 closer to the first pipette 12. The first serial conduit 15 connects the liquid outlet of the next first puncture device 11 to the liquid inlet of the previous first puncture device 11. In some alternative configurations, there may be at least three first puncture devices 11, corresponding to at least three first medical solution containers 6, with each first puncture device 11 being connected to a corresponding first medical solution container 6 by puncturing. The first puncture devices 11 are connected in series via a first series conduit 15, with one first puncture device 11 being directly connected to the end of the first aspiration conduit 12, and one first puncture device 11 being located farthest from the first aspiration conduit 12.

[0059] In some embodiments, a drip chamber 20 may be provided between the second liquid suction line 14 and the second puncture device 13. The injection line 10 may include a first three-way connector 104, a first injection branch 105, a second injection branch 106, and a spiral infusion tube 107. The three ports of the first three-way connector 104 are connected to the first injection branch 105, the second injection branch 106, and the spiral infusion tube 107, respectively. The first injection branch 105 is connected to the first liquid inlet connector 101, the second injection branch 106 is connected to the second liquid inlet connector 102, and the spiral infusion tube 107 is connected to the infusion connector 103. The first three-way connector 104 is a multi-way connector. The first three-way connector 104 can be Y-shaped. Of course, the first three-way connector 104 can also be T-shaped. The shape of the first three-way connector 104 is not limited here. The spiral infusion tube 107 is retractable. It can be extended when subjected to tension and can be retracted when released, reducing space occupation while meeting the length requirements of clinical use.

[0060] In some embodiments, the puncture device injection pipeline system 1 also includes a third puncture device 16 and a third pipette line 17. The third puncture device 16 can be connected to the third liquid container through puncture. The third pipette line 17 has two opposite ends, one end of which is connected to the first pipette line 12, and the other end of which is connected to the third puncture device 16.

[0061] The first liquid suction line 12 may include a first liquid suction branch 122 and a second liquid suction branch 123. The first liquid suction branch 122 is connected to a first puncture device 11, and the second liquid suction branch 123 is connected to the first liquid inlet connector 101. The first liquid suction branch 122, the second liquid suction branch 123 and the third liquid suction line 17 are connected via a second three-way connector 124. The third liquid suction line 17 may be provided with a third controller 171 for controlling the on-off of the line. When the third controller 171 is turned on, the third liquid suction line 16 is connected, and the first syringe 4 can draw liquid medicine from the third liquid container through the third liquid suction line 16; when the third controller 171 is turned off, the third liquid suction line 16 is disconnected. In a specific structure, the end of the third liquid suction line 16 is connected to a port of the second three-way connector 124. The second three-way joint 124 is a multi-way joint, which can be Y-shaped or T-shaped. The shape of the second three-way joint 124 is not limited here.

[0062] The third puncture device 16 can be connected to the third liquid medicine container through puncture. The third liquid medicine container can contain different liquid medicines from the first liquid medicine container 6. When different liquid medicines need to be sucked, the first controller 121 can be turned off and the third controller 171 can be turned on.

[0063] The first controller 121, the second controller 151 and the third controller 171 can be liquid-stopping clamps, which have an open state and a closed state. When a first liquid medicine container 6 needs to be replaced, the corresponding second controller 151 can be closed.

[0064] In some embodiments, the first liquid inlet connector 101 is connected to the first liquid suction line 12 via a double one-way valve 18, and the second liquid inlet connector 102 is connected to the second liquid suction line 14 via another double one-way valve 18. The double one-way valve 18 may have a syringe port, a suction port, and an infusion port. The syringe port is connected to a corresponding syringe, the suction port is connected to a corresponding liquid suction line, and the infusion port is connected to a corresponding liquid inlet connector. For example, the syringe port of one of the double one-way valves 18 is connected to the first syringe 4, the suction port is connected to the first liquid suction line 12 (for example, the suction port can be connected to the second liquid suction branch 123 of the first liquid suction line 12), and the infusion port is connected to the first liquid inlet connector 101. The double one-way valve 18 has a first working state and a second working state. In the first working state, the suction port is open and the infusion port is closed. The syringe port is connected to the suction port, and the syringe can be connected to the liquid container to aspirate liquid. In the second operating state, the infusion port is open and the suction port is sealed. The syringe port is connected to the infusion port, allowing the syringe to connect to the injection line 10 and inject the medication into the patient. The valve cavity of the double-check valve 18 can be provided with a first diaphragm and a second diaphragm. When the first diaphragm is open, the second diaphragm is sealed, and the double-check valve 18 is in the first operating state. When the first diaphragm is sealed, the second diaphragm is open, and the double-check valve 18 is in the second operating state. This double-check valve can adopt an existing structure.

[0065] In some embodiments, the first puncture device 11 farthest from the first aspiration line 12 has an air intake check valve 19. During use, when liquid medicine is to be aspirated, the air intake check valve 19 opens, allowing air to enter the first puncture device 11; when no liquid medicine is to be aspirated, the air intake check valve 19 closes. When there are at least three first puncture devices 11, the first puncture device 11 closest to the liquid medicine container of the first aspiration line 12 may not have an air intake check valve 19, the first puncture device 11 farthest from the first aspiration line 12 may have an air intake check valve 19, and the other first puncture devices 11 may not have an air intake check valve 19. The second puncture device 13 may have an air intake check valve 19. This air intake check valve 19 can use an existing structure.

[0066] As shown in Figures 5 and 6, in some embodiments, the puncture tube system 1 further includes a third aspiration tube 17 and multiple third puncture tubes 16. Two adjacent third puncture tubes 16 are connected via a second serial line 80, connecting the third puncture tubes 16 in series. This allows the third puncture tubes 16 to be sequentially connected in the direction B of the liquid medicine flow. In the direction of liquid medicine flow, one third puncture tube 16 is closest to the third aspiration tube 17, while another third puncture tube 16 is farthest from the third aspiration tube 17. The second serial line 80 is equipped with a fourth controller 801 for controlling the on / off status of the tube. The fourth controller 801 can be a liquid stop clamp.

[0067] The third liquid aspiration line 17 has two opposite ends, one end of which is connected to the third puncture device 16 closest to the third liquid aspiration line 17 , and the other end of which is connected to the first liquid inlet connector 101 .

[0068] The first liquid suction line 12 may include a first liquid suction branch 122 and a second liquid suction branch 123. The first liquid suction branch 122 is connected to a first puncture device 11, and the second liquid suction branch 123 is connected to the first liquid inlet connector 101.

[0069] The second three-way connector 124 is provided with a first controller 122 for controlling the on-off of the pipeline. The first controller 121 has a first working position and a second working position. In the first working position, the first suction branch 122 and the second suction branch 123 are connected, and the first suction branch 122 and the second suction branch 123 are disconnected from the third suction pipeline 17.

The third liquid medicine in the third liquid container can flow to the injection pipeline 10 through the second suction branch 123.

[0070] The third liquid medical container provides a third liquid medical solution, which can be different from the first liquid medical solution provided by the first liquid medical container. For example, the first liquid medical solution and the second liquid medical solution provide two different contrast agents. When aspirating a conventional first liquid medical solution, the first controller 121 can be in the first working position, as shown in FIG5 . When aspirating a special third liquid medical solution, the first controller 121 can be in the second working position, as shown in FIG6 .

[0071] By providing a plurality of third puncture devices 16 and third liquid medicine containers in series, in the flow direction B of the liquid medicine, it is possible to absorb the liquid medicine in the previous third liquid medicine container after the latter third liquid medicine container has absorbed the liquid medicine.

The two sets of third puncture devices 16 are respectively connected to the two third liquid pipetting pipelines 17, and the two third liquid pipetting pipelines 17 are respectively connected to the two first liquid pipetting pipelines 12.

[0074] Specifically, the injection line 10 may include a four-way connector 108, a first injection branch 105, a second injection branch 106, a spiral infusion tube 107, and a third injection branch 109. The four ports of the four-way connector 108 are connected to the first injection branch 105, the second injection branch 106, the third injection branch 109, and the spiral infusion tube 107, respectively. Each first suction line 12 includes a first suction branch 122 and a second suction branch 123. The first suction branch 122, the second suction branch 123, and the corresponding third suction line 17 are connected via a second three-way connector 124. The two second suction branches 123 are respectively connected to the first injection branch 105 and the third injection branch 109 via a double check valve 18.

When there are multiple first pipette lines 12, at least one of the first pipette lines 12 is connected to multiple first pipettes 11 in series, that is, each first pipette line 12 may be connected to multiple first pipettes 11 in series, or only some of the first pipette lines 12 may be connected to multiple first pipettes 11 in series. For example, as shown in Figure 8, one first pipette line 12 is connected to multiple first pipettes 11 in series, and another first pipette line 12 is connected to one first pipette 11. When there are multiple first pipette lines 12, only one or more first pipette lines 12 may be connected to the third pipette line 17, or all may be connected to the third pipette line 17, or none may be connected to the third pipette line 17.

[0077] As shown in Figures 1 to 4, a high-pressure angiography injection device 100 includes a control host 2, a first syringe 4, a second syringe 5, and the above-mentioned puncture tube injection system 1. The first syringe 4 can draw liquid medicine from the corresponding liquid container and inject the liquid medicine to the patient end. The second syringe 5 can draw liquid medicine from the corresponding liquid container and inject the liquid medicine to the patient end. The puncture tube injection system 1 includes a first liquid inlet connector 101 and a second liquid inlet connector 102. The first syringe 4 is connected to the first liquid inlet connector 101 and the first liquid suction line 12.

The infusion port of the double one-way valve 18 is connected to the first liquid inlet connector 101. The aspiration port of the double one-way valve 18 is connected to the first aspiration line 12. The second syringe 5 may be connected to the syringe port of another double one-way valve 18. The infusion port of the double one-way valve 18 is connected to the second liquid inlet connector 102. The aspiration port of the double one-way valve 18 is connected to the second aspiration line 14.

[0079] The high-pressure contrast injection device 100 may further include a support 3, which is capable of supporting the control host 2, the first syringe 4, the second syringe 5, and the puncture device injection tubing system 1. The support 3 includes a support body 30 and a shelf 31 mounted on the support body 30. The support body 30 has a certain height and can be placed upright on the ground. The control host 2 can be fixedly mounted on the support body 30. The shelf 31 includes a shelf body 36, a fixing clip 33 provided on the shelf body 36, and two bottle holders 32. The fixing clip 33 is used to mount the shelf 31 on the support body 30. The bottle holders 32 are used to place liquid medicine containers. For example, the bottle holders 32 can hold a first liquid medicine container 6 for containing contrast agent. To facilitate assembly and disassembly of the shelf 31 and the liquid medicine containers, the fixing clip 33 and the bottle holders 32 are both detachably connected to the shelf body 36 via a connecting assembly. For example, the connecting assembly includes a dovetail-shaped groove 34 provided on the shelf body 36 and a dovetail-shaped protrusion 35 matching the groove 34. The protrusion 35 is provided on the bottle holder 32 and the fixing buckle 33. The cooperation between the protrusion and the groove achieves a detachable connection. Of course, the protrusion 35 can also be provided on the shelf body 36, while the groove 34 is provided on the bottle holder 32 and the fixing buckle 33. Since the bottle holder 32 and the fixing buckle 33 are detachably connected to the shelf body 36, different models of bottle holders 32 and fixing buckles 33 can be replaced, thereby allowing the shelf 31 to match different sizes of bracket bodies 30 and different sizes of liquid medicine containers.

[0080] As shown in Figures 8 and 9, in some embodiments, the shelf 31 may include a fixing clip 33 and at least three bottle holders 32, so that the shelf 31 can hold at least three liquid medicine containers. The number of the bottle holders 32 can be set according to the design, manufacturing and use requirements. The fixing clip 33, the bottle holder 32 and the shelf body 36 are detachably fixedly connected, such as by a snap connection, plug-in connection or screw connection. The fixing clip 33 may include two parts that can be opened and closed relative to each other. When relatively closed, the fixing clip 33 can be tightly fitted on the bracket body 30; when relatively opened, the fixing clip 33 can be removed from the bracket body 30.

[0081] The high-pressure contrast injection device 100 may further include an operating panel 8 mounted on the support body 30. In a specific configuration, the control host 2 may be rotatably connected to the support body 30, thereby enabling the device to be flipped within a certain angle range. In a specific configuration, the control host 2 may include an injection pump.

[0082] During use, the control host 2 drives the first syringe 4 to draw the first liquid medicine from the first liquid medicine container 6 and drives the second syringe 5 to draw the second liquid medicine from the second liquid medicine container 7. Then, the control host 2 can drive the first syringe 4 to inject the first liquid medicine into the injection line 10 and drive the second syringe 5 to inject the second liquid medicine into the injection line 10. The first liquid medicine and the second liquid medicine are mixed in the infusion spiral tube 107 and injected into the patient end through the infusion connector 103.

[0083] With the high-pressure contrast injection device 100, the bracket 3 allows the contrast agent container or saline container to be placed vertically into the first and second puncture devices 11 and 13 of the injection pipeline system, eliminating the difficulty associated with clinical puncture. By providing the first, second, and third controllers 121, 151, and 171, it is possible to draw liquid from different liquid containers. The dual one-way valve 18 prevents the first liquid from flowing into the second liquid aspiration pipeline 14 and the second liquid from flowing into the first liquid aspiration pipeline 12. By providing multiple first puncture devices 11 and first liquid containers 6 in series, it is possible to draw liquid from the previous first liquid container 6 after the next first liquid container 6 has been completely aspirated, in the direction of liquid flow A. By making the bottle holder 32 and the fixing clip 33 detachably connected to the bracket body 30, it can be used with liquid containers of different sizes and with different models of control host 2.

[0084] As shown in Figures 10 to 13, in some embodiments, the high-pressure contrast injection device includes a control unit 2, a first syringe 4, and the aforementioned trocar injection system. The first syringe 4 is capable of drawing liquid medicine from a corresponding first liquid medicine container 6 and injecting the liquid medicine into the patient. The first liquid medicine container 6 is capable of being connected to a first trocar 11 for puncture. The high-pressure contrast injection device may also include a bracket 3, which includes a bracket body 30 and a shelf 31 mounted on the bracket body 30.

The first direction may be horizontal, i.e., the horizontal cross-section of the side panel 342 may be C-shaped. The bottom panel 341 includes a side surface 343, an upper surface 344, and a lower surface 345, which are disposed opposite each other in a second direction. The side surface 343 is located between the upper surface 344 and the lower surface 345. The second direction may be vertical. A positioning groove 346 is formed by recessing the side surface 343 along the first direction. A plugging groove 347 is formed by extending vertically through the upper surface 344 and the lower surface 345 along the second direction. The plugging groove 347 is connected to the positioning groove 346. The first puncture device 11 may include a puncture device body 111 having a relatively small outer diameter and wings 112 extending radially outward from the outer wall of the puncture device body 111, with the outer diameter of the wings 112 being larger than the outer diameter of the puncture device body 111. The puncture device body 111 has a puncture tip 113 and a connecting tail 114 at either end, respectively, which can be connected to a liquid medicine pipeline. The positioning groove 346 is adapted to fit the wings 112, and the puncture device body 111 is adapted to fit the insertion groove 347. During use, the first puncture device 11 is moved in a first direction, so that the wings 112 having a relatively large outer diameter of the first puncture device 11 are inserted into the positioning groove 346. The puncture tip 113 of the first puncture device 11 extends upward from the upper surface 344, allowing the first puncture device 11 to be installed and positioned on the base plate 341. When the first liquid medicine container 11 is installed in the mounting portion 34, the puncture tip 113 pierces the stopper 61 of the first liquid medicine container 6, thereby establishing communication between the first liquid medicine container 6 and the first puncture device 11. By pre-setting the first puncture device 11 on the bottle holder 32, the first liquid medicine container 6 is immediately connected to the first puncture device 11 when it is installed in place.

The puncture tube injection pipeline system may also include a second liquid suction line 14 and a second puncture tube 13, the second liquid suction line 14 connects the second puncture tube 13 and the injection line 10, and there may also be multiple second puncture tubes 13, each second puncture tube 13 can be connected in series via a series line. The first liquid suction line 12 and / or the second liquid suction line 14 may also be connected to a third liquid suction line 17, and the third liquid suction line 17 can be connected to a third puncture tube 16 and the corresponding first liquid suction line 12 and second liquid suction line 14. When there is only one second trocar 13 , it may have an air intake check valve 19 ; when there are multiple second trocars 13 connected in parallel, the second trocar 13 farthest from the second liquid inlet line 14 may have an air intake check valve.

[0087] The bracket 3 includes a shelf 31, which includes a shelf body 36, a fixing clip 33, and a bottle holder 34. The fixing clip 33 can be connected to the upright bracket body 30, and the bottle holder 34 can hold the first liquid medicine container 6. The bottle holder 34 can have a bottom plate 341, which is arranged corresponding to the bottle stopper 61 of the first liquid medicine container 6. When the first liquid medicine container 6 is placed on the bottle holder 34, the bottle stopper 61 can be attached to the bottom plate 341 or have a certain gap with the bottom plate 341. The first liquid medicine container 6 can contain contrast agent, physiological saline, or other liquid medicine that can be used for contrast agent injection. There can be multiple bottle holders 34, all of which can be used to hold the first liquid medicine container 6, all of which can be used to hold the second liquid medicine container 7, or a portion can be used to hold the first liquid medicine container 6 and the remaining portion can be used to hold the second liquid medicine container 7.
