Description

Technical Field

[0001] This application relates to the field of calibration equipment technology, and more specifically to a calibration device for a high-pressure injector. Background Technology

[0002] The injection head of the high-pressure injector for angiography is controlled by a servo motor via a belt-driven electric cylinder, which moves back and forth. The cylinder's extension rod connects to the rubber piston of the high-pressure injection syringe, thus controlling the pressure and flow rate of the injected fluid. Precise control of fluid pressure and dosage is crucial during surgery. This product achieves this by controlling the servo motor's speed and output torque. However, in current technology, speed and torque control largely relies on the experience of medical personnel, resulting in relatively low precision in fluid control. Utility Model Content

[0003] This application provides a calibration device for high-pressure injectors, which aims to solve the problem of low injection control accuracy in the prior art.

[0004] To address the aforementioned technical problems, embodiments of this application provide:

[0005] A calibration device for a high-pressure injector includes a frame:

[0006] A counterweight module, wherein the counterweight module is slidably connected to the frame;

[0007] A high-pressure syringe tube is mounted on the frame. A telescopic rod is slidably mounted inside the high-pressure syringe tube. A water inlet pipe for connecting to an external pressurizing device is also mounted on the high-pressure syringe tube.

[0008] The detection module is connected at one end to the telescopic rod and at the other end to the counterweight module.

[0009] Optionally, the frame includes a base plate and several columns, each of the columns being connected to the base plate, and the counterweight module being slidably connected to each of the columns.

[0010] Optionally, the counterweight module includes a counterweight platform, each of the columns is provided with a slide rail, each of the slide rails is slidably provided with a slider, and the counterweight platform is connected to each of the sliders respectively.

[0011] Optionally, the calibration device further includes a syringe sheath connected to the frame; the high-pressure syringe tube is coaxially inserted into the syringe sheath.

[0012] Optionally, the syringe sheath includes a tube body, and a connecting plate is provided at one end of the tube body along the axis of the tube body. A flange coaxial with the connecting plate is provided on the base plate, and the connecting plate is connected to the flange.

[0013] Optionally, the calibration device further includes an end seat, which is threadedly connected to the telescopic rod, and a linear ball bearing is slidably disposed on the syringe sheath, with the end seat connected to the linear ball bearing.

[0014] Optionally, the detection module includes a pressure sensor and a connecting seat that are interconnected. The connecting seat is threadedly connected to the telescopic rod, and the pressure sensor is connected to the counterweight platform.

[0015] Optionally, an adjusting piston is also slidably disposed inside the high-pressure syringe tube, and the adjusting piston is connected to the telescopic rod.

[0016] Optionally, the high-pressure syringe tube is also equipped with a drain pipe for connecting to an external water tank, and the drain pipe is equipped with a regulating check valve.

[0017] Optionally, the base plate is also threaded with several adjustable feet.

[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] This application includes a frame, on which a counterweight module is slidably mounted, and a high-pressure syringe tube is also mounted on the frame. A telescopic rod is slidably mounted inside the high-pressure syringe tube, and a water inlet pipe for connecting to an external pressurizing device is also mounted on the high-pressure syringe tube. A detection module is also mounted at the top of the telescopic rod, and the detection module is connected to the counterweight module.

[0020] In use, the counterweight of the counterweight module is adjusted as needed to apply a specified external pressure to the telescopic rod. The water inlet pipe is connected to the high-pressure injector and pressure gauge to quantitatively input high-pressure fluid into the high-pressure syringe tube.

[0021] In actual operation, the inner diameter of the high-pressure syringe is 42mm, and the minimum inner diameter of the injection outlet and tubing of the high-pressure injector is 2mm. Pressure is applied to the liquid. Based on the principle of equal internal pressure of the liquid, since the inner diameter of the high-pressure syringe is much larger than the inner diameter of the high-pressure injector, a certain volume of liquid flows through the injection outlet of the high-pressure injector, and the piston of the high-pressure syringe moves slowly relative to the liquid. In this state, the pressure at both ends of the telescopic rod is approximately equal. The external pressure applied by the counterweight module is determined by the detection module, and its parameters are determined and known. The driving force of the external water supply device depends on the speed and torque of the external motor. By continuously changing the counterweight of the counterweight module, the speed and torque parameters of the external motor under different pressure conditions can be simulated, thereby obtaining a large number of speed and torque parameters. Through the above parameters, the high-pressure injector can be calibrated, providing doctors with precise control parameters for surgery and improving the control accuracy of the injection solution.

[0022] Secondly, compared with the prior art, the calibration device described in this application can acquire a large number of detection parameters, thereby effectively correcting the detection errors of individual parameters, which is beneficial to improving the accuracy of speed and torque parameter control.

[0023] Finally, the calibration device described in this application has a simple structure and convenient counterweight adjustment, which helps to simplify the calibration procedure and improve calibration efficiency. Attached Figure Description

[0031] The image recognition-based precision feeding method for livestock and poultry in this application does not simply rely on setting a threshold to determine the feed intake and weight of individual livestock and poultry. Instead, it uses a deep learning model for analysis and judgment, which better adapts to the differences between individual livestock and poultry, thereby improving the accuracy of the judgment. Furthermore, the image recognition-based precision feeding method described in this application can monitor the feed intake and weight changes of livestock and poultry in real time. If a problem is detected, it can promptly send an alarm message to the feeder, allowing for timely intervention to ensure the healthy growth of the livestock and poultry. It can be seen that this application, through automated monitoring and intelligent judgment, significantly improves breeding efficiency, reduces labor costs, and increases economic benefits.

[0035] Implementation method 1:

[0036] Reference Figures 1 to 3 This embodiment discloses a calibration device for a high-pressure injector, including a frame 1:

[0037] The frame 1 includes a base plate 101, a plurality of uprights 102 and a plurality of adjustable feet 17. The base plate 101 is a long strip plate. Each of the adjustable feet 17 is provided on the bottom surface of the base plate 101 and is located at each corner and edge of the base plate 101. Each of the adjustable feet 17 is threadedly connected to the base plate 101.

[0038] By adjusting the foot 17, the staff can effectively adjust the level of the base plate 101, thereby improving the equipment's adaptability to uneven working environments. Moreover, its structure is simple and easy to adjust.

[0039] Each of the columns 102 is vertically arranged on the top surface of the base plate 101, and the bottom of each column 102 is connected to the base plate 101; preferably, there are two columns 102 in total.

[0040] Furthermore, the calibration device also includes a counterweight module, which includes a counterweight platform 5. The counterweight platform 5 is a long strip-shaped flat plate and is positioned directly above the base plate 101.

[0041] Each of the two columns 102 has a slide rail 6 arranged vertically on its opposite side, and a slider 7 is slidably mounted on each slide rail 6. The bottom surface of the counterweight platform 5 is provided with several connecting strips, and each connecting strip is connected to each slider 7, thereby realizing the sliding connection between the counterweight platform 5 and the frame 1.

[0042] The above-mentioned structural design can effectively reduce the motion resistance of the counterweight platform 5, thereby ensuring that the equipment can work normally under a smaller thrust and improving the detection accuracy of the equipment. On the other hand, the column 102 and the slide rail 6 can limit the movement of the counterweight platform 5, ensuring that it can only move up and down in the vertical direction, thereby improving the control accuracy of the equipment.

[0043] The top of the counterweight platform 5 is used to place counterweight modules such as weights.

[0044] Furthermore, a syringe protective tube 8 is also provided on the top surface of the base plate 101. The syringe protective tube 8 includes a hollow cylindrical tube body 801. A connecting plate 802 is provided at one end of the tube body 801 along the axis of the tube body 801. A flange 9 coaxial with the connecting plate 802 is provided on the base plate 101. The connecting plate 802 and the flange 9 are coaxially connected by connecting bolts.

[0045] The other end of the syringe sheath 8 is open to facilitate the insertion of the high-pressure syringe tube 2 into the syringe sheath 8.

[0046] Furthermore, an insertion hole is provided on the base plate 101, and an inlet pipe 4 and a drain pipe 15 are provided at one end of the high-pressure syringe tube 2. An adjustment one-way valve 16 is also provided on the drain pipe 15. The inlet pipe 4 extends through the insertion hole to connect the high-pressure injector and the pressure gauge. A connecting groove is provided on the outer circumferential surface of the syringe tube 8. The drain pipe 15 and the adjustment valve extend from the connecting groove to connect to an external water tank.

[0047] It should be noted that after the high-pressure syringe tube 2 is inserted into the syringe sheath 8, the outer wall of the high-pressure syringe tube 2 fits against the inner wall of the syringe sheath 8. Since the syringe sheath is vertically fixed to the base plate 101 by bolts, the syringe sheath 8 can effectively improve the verticality of the high-pressure syringe tube 2, preventing the high-pressure syringe tube 2 from tilting during operation, thereby ensuring the stability of the equipment and improving the reliability of the detection parameters.

[0048] Furthermore, an adjusting piston 14 is slidably disposed inside the high-pressure syringe tube 2. The adjusting piston 14 is preferably a rubber piston. The top surface of the adjusting piston 14 is threadedly connected to a telescopic rod 3, and the top end of the telescopic rod 3 extends into the high-pressure syringe tube 2.

[0049] The calibration device also includes a detection module, which includes a pressure sensor 12 and a connecting seat 13. The bottom surface of the pressure sensor 12 is connected to the connecting seat 13 by bolts, and the top surface of the pressure sensor 12 is connected to the bottom surface of the counterweight platform 5 by bolts.

[0050] The top end of the telescopic rod 3 is provided with a threaded countersunk hole, and the connecting seat 13 is threadedly connected to the threaded countersunk hole;

[0051] Furthermore, an end seat 10 is threadedly connected to the top of the telescopic rod 3. The end seat 10 is a cylindrical body. A linear ball bearing 11 is coaxially sleeved on the needle tube sleeve. The linear ball bearing 11 is slidably connected to the outer circumferential surface of the needle tube sleeve. The linear ball bearing 11 is connected to the end seat 10 by bolts.

[0052] By sitting on the linear ball bearing 11, the limiting effect on the telescopic rod 3 can be further improved, ensuring that the telescopic rod 3 can only move linearly along the axial direction, avoiding the tilting of the high-pressure syringe tube 2 during operation, thereby ensuring the stability of the equipment operation and improving the reliability of the detection parameters.

[0053] During use, counterweights such as weights are placed on the counterweight platform according to the counterweight requirements to prevent the high-pressure syringe tube from tilting during operation, thereby ensuring the stability of the equipment and improving the reliability of the detected parameters.

[0054] Because the inner diameter of the high-pressure syringe body is much larger than the diameter of the high-pressure injector tube, the high-pressure injector syringe moves slowly. In this state, the pressure at both ends of the telescopic rod is approximately equal. The external pressure applied by the counterweight module is determined by the detection module, and its parameters are fixed and known. The driving force of the external water supply device depends on the speed and torque of the external motor. By continuously changing the counterweight of the counterweight module, the speed and torque parameters of the external motor under different pressure conditions can be simulated, thereby obtaining a large number of speed and torque parameters. The high-pressure injector can be calibrated using these parameters, providing doctors with precise control parameters for surgery and improving the control accuracy of the injection solution.

[0055] Secondly, compared with the prior art, the calibration device described in this application can acquire a large number of detection parameters, thereby effectively correcting the detection errors of individual parameters, which is beneficial to improving the accuracy of speed and torque parameter control.

[0056] Finally, the calibration device described in this application has a simple structure and convenient counterweight adjustment, which helps to simplify the calibration procedure and improve calibration efficiency.
