If not handled in time or improperly, local swelling, pain, and congestion may occur in mild cases; in severe cases, surrounding subcutaneous tissue necrosis may occur, and even functional disorders may occur, which will increase the pain of the patient. Therefore, the flow of contrast agents needs to be controlled. Utility Model Content

[0027] Example 1: See Figures 1 to 3 As shown,

[0028] A contrast agent auxiliary injection device provided in the present embodiment includes a workbench 1, on which a fixing component and a transmission component are arranged. The fixing component is arranged in the direction of the output end of the transmission component. The fixing component is detachably connected with a needle tube component. A hand pressing component is arranged in the needle tube component. The output end of the transmission component abuts against the hand pressing component. During use, the inside of the needle tube component is first filled with contrast agent, and then the needle tube component is placed on the fixing component to fix the needle tube component so that the hand pressing component on the needle tube component is located on the output end of the transmission component. After the pushing speed of the transmission component is adjusted to a fixed value, the control button of the transmission component can be pressed to realize the use of the rotating component. The output end of the transmission component is first abutted against the hand pressing component. When the transmission component is controlled to output, the transmission component pushes the hand pressing component to squeeze the contrast agent in the needle tube component and flow out from the output end of the needle tube component.

[0029] Furthermore, the fixing assembly includes a placement piece 2, which is disposed on the workbench 1. The needle tube assembly includes a syringe 8, which is disposed on the placement piece 2. The placement piece 2 is used to prevent the needle tube assembly from slipping. Since the needle tube assembly is round, the needle tube assembly is prevented from slipping during use.

[0030] Furthermore, the fixing assembly includes a restraining member 3, the restraining member 3 has two frame structures arranged opposite to each other, the syringe 8 is provided with a through hole, one end of the through hole is provided with a finger pressure part 9, and the finger pressure part 9 is detachably arranged in the frame structure of the restraining member 3. Even if slipping is avoided, a large displacement will still occur when the needle is placed in use. The restraining member 3 is used to perform a second constraint on the finger pressure part 9, thereby further constraining the needle tube assembly, making it more stable during use.

[0031] Furthermore, the other end of the through hole is provided with an end cap 12, and the end cap 12 is detachably connected to an infusion tube 13, and the infusion tube 13 is connected to a heating component 14. The contrast agent is input into the syringe 8 through the end cap 12, and then injected into the heating component through the hand pressing component for heating, and then input into the patient's body through the heating end.

[0032] Furthermore, a hand-pressing assembly is provided in the syringe 8, and the hand-pressing assembly includes a push rod 10. The push rod 10 is provided with an output end and an extrusion end. The output end of the push rod 10 is provided inside the syringe 8. The output end of the push rod 10 is provided with a seal 17. The seal 17 is provided with a pushing end 16. The output end of the pushing end 16 is adapted to the end 12. The output end of the syringe 8 is the same as the end of the hand-pressing assembly, so that during use, the contrast agent can be almost completely pushed out to avoid wasting the contrast agent.

[0033] Furthermore, a pressing piece 11 is provided at the extrusion end of the push rod 10. The pressing piece 11 is used to abut against the output end of the transmission component, so that when the transmission component is started, the transmission component can push the pressing piece 11 to move, thereby achieving the purpose of delivering the contrast agent.

[0034] Furthermore, the transmission component includes a base 7. A control button for controlling the pushing device 5 is provided on the base 7. A pushing device 5 is provided at one end of the base 7 facing the fixing component. A pushing block 4 is provided at the output end of the pushing device 5. When the control button is pressed, the pushing device 5 starts to move at a constant speed, pushing the pressing hand component to push out the contrast agent. When the control button is no longer pressed, the pushing device stops operating, thus making the operation convenient.

[0035] Furthermore, a sliding block 18 is provided on the pushing block 4, and a sliding groove is provided on the workbench 1. The sliding block 18 is slidably arranged in the sliding groove. During use, when the pushing block 4 pushes the pressing hand component, if there is a large deviation, it is easy to damage the equipment. After the sliding block 18 is provided on the pushing block 4, the sliding block 18 can restrict the direction of the pushing block 4, avoiding the situation of deviation during pushing and causing damage, and at the same time increasing the stability of the structure.

[0036] Furthermore, the seal 17 is hermetically connected to the syringe 8, avoiding the leakage of the contrast agent during use and improving the utilization efficiency of the contrast agent.

[0037] Furthermore, the frame structure of the restraint 3 is a "C" - shaped structure. The diameter of the input end of the heating component 14 is larger than the diameter of the output end of the heating component 14. A needle for acting on the patient is provided at the output end of the heating component 14. The output end of the pushing device 5 is arranged at the center of the pushing block 4. The centers of the output end of the pushing block 4 and the pressing piece 11 are located at the same position. The restraint 3 adopts a square - frame structure, which can well restrain the syringe assembly, making the pushing process more stable. The diameter of the input end of the heating component 14 is larger than the diameter of the output end of the heating component 14. Since the liquid input volume is the same, the flow rate at the output end of the heating component 14 is greater than the flow rate at the input end of the heating component 14, avoiding the situation of small air bubbles inside the contrast agent.
