Description

Technical Field

[0001] The present invention relates to the field of medical devices, in particular to a contrast agent remote control injection device which can be adapted to multiple types of syringes. Background Art

[0002] Existing contrast agent injection equipment used in medical diagnosis and treatment is widely used in imaging-assisted examinations such as CT, MRI, and DSA, especially playing an important role in angiography, cholangiography, hysterosalpingography, and enhanced scanning.

[0003] Contrast agent injection can be performed manually or automatically. Manual injection is often used for examinations that do not require simultaneous imaging, such as intravenous pyelography, as the examination cannot begin until the contrast agent enters the urinary system through the bloodstream. Its advantages include ease of administration. However, its disadvantages include: 1. For examinations requiring simultaneous imaging, the injector is exposed to radiation; 2. Manual injection lacks effective control over injection pressure, resulting in significant deviations in injection speed and dose.

[0004] Automatic injection, most commonly achieved with a high-pressure syringe, uses a semi-automatic pressure pump or partially electronically controlled infusion system. It is primarily used for CT, MRI enhancement, angiography, and interventional examinations. Its advantages include high injection accuracy and the ability to dynamically monitor the injection process. However, its disadvantages are: 1. The equipment is expensive; 2. The same type of syringe must be replaced after each patient, which is inconvenient, and it cannot accommodate consumables of varying specifications, resulting in low adaptability. 3. The connection between the push rod and the drive end is often completed manually, resulting in unstable coupling and difficulty in repeated operation.

[0005] Therefore, a remote control injection device that is simple, easy to operate, relatively inexpensive, and highly compatible with injection devices is invented, which has high clinical application value. Summary of the Invention

[0019] Beneficial effects:

[0020] 1. This invention utilizes a motorized slide, coupled with a screw lift and integrated injection assembly, to achieve precise spatial control of the syringe's position. This automates and stabilizes the entire contrast agent process, from aspiration to injection. Compared to the common issues of injection deviation and difficulty in repeatable positioning found in existing manual or semi-automatic injection devices, this effectively overcomes the technical bottlenecks of error accumulation and low injection efficiency caused by manual operation.

[0022] 3. This invention incorporates a servo system and a latching mechanism controlled by the injection assembly. A spring-loaded T-block and latch automatically lock the syringe plunger head, enabling rapid docking and automatic release. This effectively improves the efficiency and mechanical response speed of the injection process. Unlike traditional plunger connection mechanisms that rely on manual pushing or simple latching, this design avoids the impact of repeated operations on device consistency and resolves the issue of unstable disconnection.

[0036] The injection assembly includes a fixed frame 11, the bottom of the fixed frame 11 is fixedly connected to the side of the mounting seat 10 away from the bracket 6, the top of the fixed frame 11 is fixedly connected to a fixed cylinder 12, the top of the fixed cylinder 12 is fixedly connected to a servo motor 13, the output end of the servo motor 13 is fixedly connected to a screw 14, the outer side of the screw 14 is threadedly connected to a movable rod 15, and the outer side of the movable rod 15 is slidably connected to the inside of the fixed cylinder 12.

[0037] Specifically, the servo motor 13 drives the screw 14 to achieve precise control of the movable rod 15 in the vertical direction, and then drives the syringe push rod to move up and down through the connecting component to complete the suction or injection action. The control accuracy of the servo motor can achieve fine adjustment of the injection flow rate and dosage.

[0038] Both sides of the lead screw 8 are rotatably connected to the inside of the bracket 6 , and the outer side of the movable seat 9 is slidably connected to the inside of the bracket 6 .

[0039] Specifically, the screw 8 rotates under the drive of the motor 7, causing the movable seat 9 to move linearly along the axial direction of the screw, driving the mounting seat 10 and its affiliated injection structure to rise and fall vertically, thereby realizing the regulation of the height of the syringe and ensuring that the syringe can successfully aspirate the medicine in the container placed on the operating disk 42.

[0040] The connecting assembly includes a connecting seat 16, the top of the connecting seat 16 is fixedly connected to the bottom of the movable rod 15, and T-blocks 17 are slidably connected on both sides of the connecting seat 16. A connecting block 18 is fixedly connected to the bottom of the T-block 17, and a clamping block 19 is fixedly connected to the bottom of the connecting block 18. A clamping groove 20 is provided on the adjacent side between the two clamping blocks 19, and a spring 21 is provided on the opposite side between the two T-blocks 17.

[0041] Specifically, driven by the servo motor 13, the connecting seat 16 drives the T-block 17 and the clamping block 19 to move downward and contact the syringe push rod. The slope design of the clamping block 19 can automatically align with the circular structure of the push rod head and is clamped with the help of the spring 21 to ensure that the syringe push rod and the connecting assembly are stably engaged and can be driven repeatedly.

[0042] One end of the spring 21 is fixedly connected to the middle of the T-shaped block 17 , and the other end of the spring 21 is fixedly connected to the inner wall of the connecting seat 16 .

[0043] Specifically, the spring 21 is compressed during the expansion of the block 19, and then releases the elastic force during the downward movement of the structure to push the T-block 17 back to the center, so that the block 19 completes the locking action of the circular structure at the top of the syringe push rod, realizing automatic locking without human intervention.

[0044] The syringe fixing assembly includes a fixing box 22, the outer side of the fixing box 22 is fixedly connected to the side of the mounting base 10 away from the bracket 6, the top wall of the fixing box 22 is fixedly connected to the support 23, the bottom of the support 23 is fixedly connected to the motor 2 24, the output end of the motor 24 is fixedly connected to the gear 25, the two sides of the bottom wall of the fixing box 22 are slidably connected to the slide 26, the top of the slide 26 is fixedly connected to the rack 27, the two racks 27 and the gear 25 are meshed, the side of the rack 27 away from the mounting base 10 is fixedly connected to the connecting arm 28, the side of the connecting arm 28 away from the rack 27 is fixedly connected to the clamping base 29, the top of the clamping base 29 is provided with a groove 30, and the bottom of the clamping base 29 is fixedly connected to the syringe fixing base 33.

[0045] Specifically, motor 24 drives gear 25 to rotate, causing rack 27 to move synchronously in the same direction or opposite direction, thereby driving connecting arm 28 and syringe fixing seat 33 to adjust the spacing, thereby adapting to the barrel fixing requirements of different types of syringes, and groove 30 realizes precise engagement with the protruding handle of the syringe.

[0046] The needle handle fixing assembly includes a column 36, the bottom of the column 36 is fixedly connected to the top of the connecting arm 28, the top of the column 36 is fixedly connected to an electric push rod 37, the output end of the electric push rod 37 is fixedly connected to a pressure cover 38, and a groove 30 is provided at the bottom of the pressure cover 38.

[0047] Specifically, when the syringe is fixed, the electric push rod 37 starts to drive the pressure cover 38 to press down, so that the groove 30 at the bottom fits with the syringe handle structure, forming a second layer of clamping force, and cooperating with the holder 29 to prevent the syringe from shifting during suction or injection.

[0048] The adjusting assembly includes a fixed plate 2, the bottom of which is fixedly connected to the top of the telescopic rod 39, the inside of the fixed plate 2 is rotatably connected to the movable plate 3, the outer side of the fixed plate 2 is threadedly connected to an adjusting bolt 1 4, the top of the movable plate 3 is fixedly connected to a connecting frame 43, the top of the connecting frame 43 is penetrated by an adjusting bolt 2 45, the middle part of the adjusting bolt 2 45 is rotatably connected to a connecting block 44, the top of the connecting block 44 is fixedly connected to the bottom of the bracket 6, and one side of the outer side of the adjusting bolt 2 45 is threadedly connected to a fastening nut 46, which is embedded in the side wall of the connecting frame 43.

[0049] When using the device to perform an injection operation on a patient, the movable disk 3 and the fixed disk 2 can be released from the locked state by loosening the adjusting bolt 1 4. At this time, the movable disk 3 can be rotated inside the fixed disk 2 by rotating the support 6, and then the orientation of the device in the horizontal direction can be adjusted. After adjusting to a suitable angle, the adjusting bolt 1 4 can be tightened, and then the movable disk 3 and the fixed disk 2 are locked and fixed. Then, the adjusting bolt 2 45 is loosened to release the locking state between the connecting block 44 and the connecting frame 43. At this time, the angle of the device can be adjusted up and down, and then after adjusting to a suitable angle, the locking bolt 2 45 is tightened again to lock it with the fastening nut 46, and then the connecting block 44 and the connecting frame 43 are locked and fixed. The angle adjustment of the device before use is completed, and then the telescopic rod 39 can be started, and then the overall height of the device can be adjusted according to the patient's body shape.

[0050] Slide rods 31 are fixedly connected on both sides of the fixed box 22, and the slide seat 26 is slidably connected to the outside of the slide rods 31. A slide groove 32 is opened on the side of the fixed box 22 away from the mounting seat 10, and the outside of the connecting arm 28 passes through and is slidably connected to the inside of the slide groove 32.

[0051] Specifically, the slide rod 31 and the slide groove 32 provide guidance and limitation for the syringe clamping assembly, ensuring stable sliding and no deviation during the gear rack drive process, and enhancing the parallelism and synchronization of the movement of the holder 29 and the pressure cover 38.

[0052] A mounting bracket 34 is fixedly connected to the side wall of the syringe fixing seat 33 , and a camera 35 is installed on the top of the mounting bracket 34 .

[0053] Specifically, the camera 35 is used to monitor the operating status of the syringe and the condition of the patient's puncture site in real time, so that medical staff can remotely observe and judge whether the operation is normal. It supports enabling emergency stop or pause commands through the software interface to ensure the visibility of the operation and remote intervention capabilities. At the same time, when an abnormal state is detected, external medical staff can prompt the patient by activating the alarm light 1.

[0054] Working principle: During the injection of contrast agent, the pre-prepared contrast agent container is first placed on the placement area 3, and then the syringe is placed between the two syringe holders 33. At this time, the staff starts the motor 24 inside the fixed box 22 to drive the gear 25 to rotate. The gear 25 rotates and drives the two racks 27 engaged with it to move toward each other synchronously. At this time, the connecting arms 28 on the two racks 27 will synchronously drive the two grooves 30 and the syringe holders 33 to move toward each other synchronously until the two syringe holders 33 and the barrel part of the syringe are in contact. By adjusting the distance between the two syringe holders 33, it can adapt to the use of syringes of different sizes. When the two syringe holders 33 fix the barrel part of the syringe, the two protruding handle structures at the top of the syringe will be stuck in the groove 30 on the holder 29. At this time, the two electric push rods 37 are started again to push the pressure cover 38 at the bottom thereof downward, so that the pressure cover 38 is pressed tightly against the top of the holder 29, and at the same time, the groove 30 at the bottom of the pressure cover 38 clamps the handle part at the top of the needle tube, and then further fixes the handle part, so that the syringe can be installed.

[0055] After the syringe is fixed, the servo motor 13 is started to drive the screw 14 to rotate, and the screw 14 drives the movable rod 15 to move downward, so that the two blocks 19 on the connecting assembly will first contact the push rod of the syringe when moving downward. Through the slope structure at the bottom of the block 19 and the drive of the servo motor 13, the two blocks 19 will move toward both sides along the outer contour of the circular structure at the top of the push rod of the syringe under the action of force. During the process, the block 19 will drive the top connecting block 18 and the T-block 17 to move toward the outer edge of the inside of the connecting seat 16, and the T-block 17 will synchronously compress the spring 21 until When the two blocks 19 expand to the same size as the diameter of the circular structure at the top of the syringe push rod, the block 19 will continue to move downward under the drive of the servo motor 13 until the top of the block 19 moves below the circular structure at the top of the push rod. At this time, the compressed spring 21 resets and pushes the two T-blocks 17 to move toward each other, and then driven by the connecting block 18, the two blocks 19 will also move downward synchronously and be stuck at the bottom of the circular structure at the top of the push rod. With the help of the structural groove 30 thereon, the block 19 can be completely fitted on the outside of the syringe push rod, thereby realizing the connection between the syringe push rod and the injection assembly.

[0056] The medical professional first activates servo motor 7 to adjust the syringe's height, positioning the needle tip below the level of the contrast agent solution. The medical professional then activates servo motor 13 to draw the contrast agent into the syringe. The needle is then removed and the connecting tube is used to connect the syringe's injection port to the opening of the patient's indwelling catheter. The medical professional can then remotely control the device to inject the contrast agent. This process is accomplished through the coordination of the device's servo control system and the external operator terminal, allowing the medical professional to control the injection process through the remote terminal.

[0057] At this time, the servo motor 13 of the injection assembly starts again and drives the movable rod 15 downward through the screw 14. At this time, the connecting seat 16 will move downward synchronously. With the help of the pressure applied by the connecting seat 16 to the syringe push rod, the syringe push rod structure moves downward and pushes the piston structure downward, and then the contrast agent inside the syringe is injected into the patient's body. At this time, the servo motor 13 is controlled by a precise servo control system, and then the injection time and speed are controlled. At the same time, medical staff outside the injection room can view the contrast agent injection inside the syringe and the patient's injection site through the cameras 35 installed on the two mounting brackets 34, and then determine whether it is necessary to stop the device by operating the emergency stop function on the external system. Or when the patient feels unwell, the device can be stopped by pressing the emergency stop switch 5 on the side of the base 2.

[0058] When the injection is complete, the electric push rod 37 starts to drive the pressure cover 38 upward, thereby releasing the clamped syringe handle. Then, the motor 24 starts again and drives the gear 25 to rotate in the opposite direction, which in turn causes the two racks 27 to move in opposite directions. The two syringe holders 33, driven by the connecting arm 28, will move synchronously in opposite directions, thereby releasing the clamped syringe barrel. At this time, the syringe is clamped between the two clamping blocks 19 by the circular structure on the top of its push rod to prevent it from falling. After waiting for the staff to enter the injection room, they can pull the syringe forward and remove it conveniently.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
