[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides an electronic oscillating injection device, including: a main body; an oscillation mechanism 200 disposed on the main body, the oscillation mechanism 200 including a rocker arm 205 capable of oscillating; and an injection mechanism 300 including a housing, a clamping member 303, and a push handle 302; the housing is disposed on the rocker arm 205 and moves with the rocker arm 205; the clamping member 303 is retractably disposed on one side of the housing, for example, the clamping member 303 can be disposed on the front side of the housing, for clamping the syringe; the push handle 302 is retractably disposed on the other side of the housing, for example, the push handle 302 can be disposed on the right side of the housing. When the syringe is clamped by the clamping member 303, the push handle 302 abuts against the syringe plunger, and the plunger of the syringe is driven to move by the push handle 302 to push out the liquid medicine in the syringe.

[0038] The electronic oscillating injection device provided in this embodiment is suitable for diagnostic or therapeutic reagents that are frequently mixed during treatment, such as microsphere injections. It combines oscillation and injection into one unit. The oscillation mechanism 200 can be used to make the entire injection mechanism 300 continuously oscillate, so that the mixed drug solution in the syringe remains suspended throughout the process. At the same time, the injection mechanism 300 generates a large injection force. When used in conjunction with the syringe, it can not only achieve the mixed injection of large molecular weight drugs, but also be used to accurately inject various types of small-dose drugs into the patient's body.

[0039] The main body includes a connected main casing 100; the main casing 100 has an internal cavity, and the oscillation mechanism 200 and the injection mechanism 300 are both located inside the main casing 100.

[0040] The oscillation mechanism 200 further includes a first motor 201 and a first transmission assembly. The first transmission assembly includes a gear support 204, a gear shaft 206, and a bevel gear 207. The bevel gear 207 and the gear shaft 206 are both mounted on the gear support 204. The rocker arm 205 is connected to the bevel gear 207 via the gear shaft 206. The first motor 201 is connected to the bevel gear 207 and is used to drive the bevel gear 207 to rotate, thereby driving the rocker arm 205 to oscillate.

[0041] like Figure 2 As shown, the oscillation mechanism 200 also includes a base plate 213, a motor bracket 203, a control unit, and a power supply 208. For example, the base plate 213 can be bolted to the inner bottom wall of the main unit housing 100. For example, the motor bracket 203 can be bolted to the top surface of the base plate 213, and the motor bracket 203 and the base plate 213 can be kept perpendicular. For example, the gear support 204 can be bolted to the end of the motor bracket 203 away from the base plate 213. For example, the first motor 201 can be a stepper motor, and the body of the first motor 201 can be bolted to the horizontal plate of the motor bracket 203. The output shaft of the first motor 201 extends from the horizontal plate of the motor bracket 203 and is connected to the bevel gear 207, and then connected to the rocker arm 205 through the gear shaft 206 for transmission. For example, two limit screws can be provided, and the two limit screws pass through the rocker arm 205 to lock the rocker arm 205 and the gear shaft 206. The control unit includes a servo driver 202 and a control board 209. For example, the servo driver 202 and the control board 209 can be bolted to the base plate 213 and are electrically connected to the first motor 201. In use, the control board 209 sends control signals to the servo driver 202, which controls the speed and direction of rotation of the first motor 201. When the first motor 201 rotates, it can be driven by the first transmission assembly to move the rocker arm 205.

[0042] In addition, the oscillation mechanism 200 also includes a position detection device 212 and a photoelectric sensor detection disk 211; the photoelectric sensor detection disk 211 detects the operating status of the first motor 201 and provides feedback through the position detection device 212.

[0043] The base plate 213 is also equipped with a proximity switch assembly 210, which can detect the opening and closing of the main unit housing 100 door to control the operation and stop of the equipment, and also play a role in safety protection.

[0044] like Figure 3 , Figure 4 As shown, the injection mechanism 300 also includes a second motor mounting base, a second motor 308, a screw 309, a second transmission structure, a sliding table 314, and a guide rod 310.

[0045] The second motor mounting base includes an L-shaped profile 305, a motor module L-plate 306, and a motor module R-plate 307. The second transmission structure includes a drive gear 311, an intermediate gear 312, and a screw gear 313.

[0046] For example, the housing can be composed of a front outer shell 301 and a rear outer shell 304 that are interlocked, with an L-shaped profile 305 disposed inside the housing. A motor module L-plate 306 is disposed at one end of the L-shaped profile 305, and a motor module R-plate 307 is disposed at the other end of the L-shaped profile 305. The L-shaped profile 305, the motor module L-plate 306, and the motor module R-plate 307 form a semi-enclosed cavity. A push handle 302 extends into the cavity; a sliding table 314 is fitted onto the end of the push handle 302, and the two can be integrated. The sliding table 314 is located within the cavity, and teeth are provided on its inner peripheral wall. For example, the second motor 308 can be a stepper motor, and the second motor 308 can be mounted on the inner side of the motor module L-plate 306. The drive gear 311, intermediate gear 312, and screw gear 313 are located on the outer surface of the L-plate 306 of the motor module. The drive gear 311 is connected to the output shaft of the second motor 308. The drive gear 311 meshes with the intermediate gear 312, and the intermediate gear 312 meshes with the screw gear 313. The screw gear 313 is sleeved on the end of the screw 309, so that the second motor 308 can drive the screw 309 to rotate through the drive gear 311, intermediate gear 312, and screw gear 313. The screw 309 can be disposed in the cavity and mesh with the sliding table 314. The guide rod 310 is disposed parallel to the screw 309 in the cavity and passes through the interior of the sliding table 314. When the second motor 308 rotates, it can transmit power to the screw 309 through the drive gear 311, intermediate gear 312 and screw gear 313. When the screw 309 rotates, it drives the push handle 302 to move through the sliding table 314. Due to the limiting effect of the guide rod 310, the push handle 302 can move linearly, thereby applying pressure to the syringe plunger.

[0047] The injection mechanism 300 also includes an encoder 315, a position detector 317, and a pressure sensor 316. The encoder 315 is disposed within the cavity and connected to the second motor 308, used to detect the operating parameters of the second motor 308. The position detector 317 is positioned across the motor module L plate 306 and the motor module R plate 307, used to detect the axial movement position of the sliding table 314. For example, the position detector 317 may have a detection part, which can be a T-shaped component. The T-shaped component can slide relative to the position detector 317, and is engaged within the sliding table 314. The T-shaped component moves synchronously with the sliding table 314 as it moves, and the position detector 317 obtains the position of the sliding table 314 by detecting the position of the T-shaped component.

[0048] like Figure 5As shown, the injection mechanism 300 also includes a pressure sensor 316 disposed within the end of the plunger 302, for detecting the pressure applied by the plunger 302 to the syringe plunger. For example, the pressure sensor 316 can be mounted on the contact surface between the plunger 302 and the plunger to accurately measure the pressure applied to the plunger.

[0049] like Figure 6 As shown, the electronic oscillating injection device also includes a drug delivery device 400, which includes a one-way three-way valve 401, an extension tube 402, and a conduit, specifically a microcatheter 404.

[0050] One port of the one-way three-way valve 401 is connected to the outlet of the syringe. Another port of the one-way three-way valve 401 is connected to one end of the extension tube 402, and this port only allows the medication to move downstream of the extension tube 402, meaning the medication can only flow out and not in, preventing backflow of the medication into the syringe. The last port of the one-way three-way valve 401 is used to connect to the contrast agent reservoir 405, and this port only allows the contrast agent in the contrast agent reservoir 405 to move towards the one-way three-way valve 401, meaning the contrast agent can only flow in and not out, preventing backflow of the contrast agent from the syringe into the contrast agent reservoir 405.

[0051] The other end of the extension tube 402 is connected to the inlet of the bubble sensor 403, and the outlet of the bubble sensor 403 is connected to one end of the microcatheter 404. The other end of the extension tube 402, via the bubble sensor 403, is used to detect bubbles within the tube and is connected to one end of the microcatheter 404 for delivering the medication. When bubbles are detected in the extension tube 402, the gas is first expelled before connecting the microcatheter 404.

[0052] During use, after the medication is fully injected into the syringe, a portion of the medication remains in the microcatheter 404 and cannot enter the body. At this point, pulling out the syringe plunger will block the connection between the one-way three-way valve 401 and the extension tube 402, while the medication connected to the contrast agent reservoir 405 of the one-way three-way valve 401 will be drawn into the syringe. Afterward, injecting the medication again will push the previously drawn-in contrast agent into the body along with the medication in the microcatheter 404. This operation can completely inject the remaining medication in the microcatheter 404, avoiding waste.

[0053] like Figure 7As shown, a touch-screen operating system 500 is installed on the side wall of the main unit casing 100, including a touch screen display 501 and physical buttons 502. The oscillation mechanism 200, the injection mechanism 300, and the touch screen display 501 are all electrically connected to the control unit, and the operating parameters of the oscillation mechanism 200 and the injection mechanism 300 can be adjusted through the touch screen display 501. The physical buttons 502 include buttons for controlling the start, pause, and fast-release of the oscillation mechanism 200 and the injection mechanism 300. For example, the touch screen display 501 can retain four configuration menus, each of which can save all the setting parameters under that configuration. For example, the touch screen display 501 can be a 7-inch LCD screen, which can display and set parameters such as: flow rate setting, flow rate, injection time, injection pressure, fast-release speed, pressure alarm threshold, preset volume, cumulative volume, reverse amplitude, forward amplitude, reverse speed, forward speed, reverse acceleration, forward acceleration, reverse interval time, and forward interval time. The instrument alarms when injection is obstructed and the injection pressure reaches the set value. Corresponding warnings or prompts are displayed on the touchscreen display 501 when the injection volume approaches the set input volume, the infusion is completed, or the set injection volume is exceeded. In addition, three physical buttons 502 are provided, with the following functions: Start (pressing the "Start" button initiates injection / oscillation); Pause (pressing the "Pause" button pauses injection / oscillation); Quick Drain (pressing the "Quick Drain" button initiates a quick drain action, releasing the button stops the quick drain and resumes the previous action, allowing the operator to quickly perform auxiliary operations.

[0054] like Figure 8 As shown, the electronic oscillating injection device also includes a remote control console 600. The remote control console 600 is electrically connected to the oscillation mechanism 200 and the injection mechanism 300 via a connecting cable 601, allowing all settings and controls on the touch screen 501 to be performed on the remote control console 600. The remote control console 600 is also equipped with an emergency stop button, which can be used to cut off the power and stop the operation in case of unexpected risks. This not only facilitates treatment for medical personnel but also fully protects their health. This design allows for operation outside the operating room, reducing radiation exposure to the operator.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
