Description

Technical Field

[0001] This application belongs to the field of high-pressure injector technology, specifically a high-precision quantitative control high-pressure injection device. Background Technology

[0002] High-pressure injectors, as auxiliary equipment in radiological diagnostic and treatment systems, have gradually been applied clinically with the development of technologies such as X-rays, rapid film changers, image intensifiers, and artificial contrast agents. The basic function of a high-pressure injector is to rapidly and accurately inject a sufficient amount of high-concentration X-ray contrast agent into the examination site within a certain time by percutaneous puncture into a blood vessel or through the body's existing orifices. This allows for diagnostic imaging and treatment of lesions. Existing contrast injection equipment is generally divided into two types: syringe-push type and peristaltic pump delivery type. It is usually necessary to mix physiological saline and contrast solution to different concentration ratios before injecting them into the blood vessel.

[0003] For example, patent CN219230991U discloses a high-pressure injection device, which includes a mounting base, a pressure detection component, and a linear module. The mounting base includes a first connecting plate and a second connecting plate. A third connecting plate is fixedly mounted on each of the two opposite sidewalls of the first connecting plate. The second connecting plate is fixedly mounted on the sidewall of the third connecting plate away from the first connecting plate. The linear module is located between the first and second connecting plates, and a push rod is fixedly mounted on the linear module. The linear module is used to drive the push rod to abut against a piston. The pressure detection component is located on the first connecting plate and is used to detect the thrust of the push rod. This application has the advantages of facilitating accurate acquisition of the pressure exerted by the push rod on the piston, effectively closed-loop control to reduce the risk of syringe damage and personnel injury due to pressure runaway, and improving the safety of use.

[0004] However, the high-pressure injection device in this application lacks a structure for positioning and adjusting the position of the syringe, resulting in poor injection accuracy. Utility Model Content

When the lead screw is rotated, the housing can be moved left and right. In use, the arm can be placed on the tray above the rotating seat. Then, the rotating handle can be held and rotated to move the housing on the surface of the lead screw left and right. At the same time, the positioning laser on the side of the injection sleeve is activated for positioning. Finally, the hydraulic rod is activated to adjust the housing to move downward, allowing the injection sleeve to move above the arm for injection.

[0008] In a preferred embodiment, a rotating handle is fixedly connected to the top end of the lead screw and the outer end located on the left fixed platform.

Then, the rotating handle can be held to rotate, causing the housing on the lead screw surface to move left and right. When adjusting the left and right position of the housing, the positioning laser on the side of the injection sleeve is activated for positioning. Finally, the hydraulic rod is activated to adjust the housing downwards, moving the injection sleeve above the arm for injection. When the tray is pressed down, the spring seat slides downwards, causing the contact inside the tray to press against the surface of the sensor seat. When the sensor seat is contacted by the contact, a signal is sent to the housing. The signal can be observed on the display screen, and the injection device can be controlled to perform injection.

[0029] Example:

[0030] Reference Figure 1-3The system includes a support rod 1, a rotating seat 8 rotatably connected to the top of the support rod 1, a right extension frame 6 fixedly connected to the right end of the rotating seat 8, a left extension frame 7 fixedly connected to the left end of the rotating seat 8, a housing 12 fixedly installed on the side end of the right extension frame 6, a hydraulic rod 13 installed on the top of the right extension frame 6, a left fixed platform 14 fixedly installed at the top of the hydraulic rod 13, a lead screw 16 rotatably connected inside the left fixed platform 14, a housing 19 threadedly connected to the surface of the lead screw 16, a mounting base 25 fixedly connected to the lower end of the housing 19, an injection sleeve 27 installed at the lower end of the mounting base 25, and multiple positioning lasers 26 fixedly installed on the side end of the mounting base 25.

[0031] Support rod 1 supports the device. A rotatable rotating base 8 is mounted on the top of support rod 1. A left extension frame 7 and a right extension frame 6 are conveniently mounted on the left and right ends of the rotating base 8. A left fixed platform 14 and a right fixed platform 18 are mounted on the top of the right extension frame 6 and the left extension frame 7. Activating the hydraulic rod 13 moves the left and right fixed platforms 14 and 18 up and down. A lead screw 16 is rotatably connected inside the left and right fixed platforms 14 and 18. Rotating the lead screw 16 moves the housing 19 left and right. In use, the arm is placed on the tray 5 above the rotating base 8. The arm is then gripped and rotated using the handle 15, causing the housing 19 on the surface of the lead screw 16 to move left and right. Simultaneously, the positioning laser 26 on the side of the injection sleeve 27 is activated for positioning. Finally, the hydraulic rod 13 is activated to adjust the housing 19 downwards, moving the injection sleeve 27 above the arm for injection. Rotating the rotating base 8 adjusts the angle of the housing 19, facilitating operator use and control of the injection device and improving its versatility.

[0032] Reference Figure 1 A rotating handle 15 is fixedly connected to the top of the lead screw 16 and the outer end of the left fixed platform 14. By gripping and rotating the rotating handle 15, the left and right positions of the housing 19 can be adjusted.

The left end of the lead screw 16 is rotatably connected to the right fixed platform 18, and a left extension frame 7 is installed at the lower end of the right fixed platform 18. When adjusting the left and right positions of the housing 19, the slide rod 17 can be used to improve the stability of the housing 19 during movement.

[0034] Reference Figure 3A left limiting bracket 21 is fixedly connected to the lower left side of the housing 19. The left limiting bracket 21 has a threaded slot 22 inside. The injection sleeve 27 is installed at the lower end of the mounting base 25. When it is necessary to limit the injection sleeve 27, the left limiting bracket 21 and right limiting bracket 23 on the side of the injection sleeve 27 can be used for limiting. The left limiting bracket 21 and right limiting bracket 23 have arc-shaped grooves inside, which can be used to clamp the injection sleeve 27.

[0035] Reference Figure 3 A right limiting frame 23 is slidably connected to the lower right side of the housing 19, and a screw 24 is provided inside the right limiting frame 23. When it is necessary to limit the injection sleeve 27, the right limiting frame 23 can be slid first so that the bottom of the right limiting frame 23 fits against the bottom of the left limiting frame 21. Then, the screw 24 is rotated and inserted into the threaded slot 22 in the left limiting frame 21, thereby clamping and limiting the middle injection sleeve 27 and improving the stability of the device.

[0036] Reference Figure 1 A display screen 20 is mounted on the surface of the housing 19. The display screen 20 facilitates the operation of the observation equipment by staff.

A tray 5 is fixedly connected to the top of the spring seat 11. A contact 10 is fixedly connected inside the tray 5 and above the sensor seat 9. When the tray 5 is pressed down, it can slide down through the spring seat 11, allowing the contact 10 inside the tray 5 to press down to the surface of the sensor seat 9 for contact. When the sensor seat 9 is contacted by the contact 10, a signal can be sent to the housing 19. The signal can be observed using the display screen 20 and the injection device can be controlled to perform injection.

[0038] Reference Figure 1 The lower end of the support rod 1 is fixedly connected to the base 2, and the lower end of the base 2 is fixedly connected to multiple support legs 3. Universal wheels 4 are installed at the lower ends of the support legs 3. The multiple support legs 3 installed below the base 2 improve the stability of the device, and the universal wheels 4 at the lower ends of the support legs 3 facilitate quick movement of the device.

[0039] The implementation principle of this high-precision quantitative control high-pressure injection device is as follows: During use, the arm can be placed on the tray 5 above the rotating seat 8. Then, the rotating handle 15 can be held and rotated to move the housing 19 on the surface of the lead screw 16 left and right. When adjusting the left and right position of the housing 19, the sliding rod 17 can be used to improve the stability of the housing 19 during movement. Simultaneously, the positioning laser 26 on the side of the injection sleeve 27 is activated for positioning. Finally, the hydraulic rod 13 is activated to adjust the housing 19 downwards, allowing the injection sleeve 27 to move above the arm for injection. When the rotating seat 8 is rotated, the angle of the housing 19 can be adjusted, facilitating the operator's use and control of the injection device and improving its applicability.

[0040] When it is necessary to limit the injection sleeve 27, the left limiting frame 21 and right limiting frame 23 on the side of the injection sleeve 27 can be used for limiting. The left limiting frame 21 and right limiting frame 23 have arc-shaped grooves inside, which can be used to clamp the injection sleeve 27. First, slide the right limiting frame 23 so that the bottom of the right limiting frame 23 fits against the bottom of the left limiting frame 21. Then, rotate the screw 24 and insert the screw 24 into the threaded slot 22 in the left limiting frame 21, thereby clamping and limiting the injection sleeve 27 in the middle, improving the stability of the device. When the tray 5 is pressed down, it can slide down through the spring seat 11, so that the contact 10 inside the tray 5 is pressed down to the surface of the sensing seat 9 for contact. When the sensing seat 9 is contacted by the contact 10, it can send a signal to the housing 19. The signal can be observed using the display screen 20 and the injection device can be controlled to inject. This device is equipped with a positioning adjustment structure for the syringe, which can quickly adjust and accurately position the injection position, improving the accuracy of the device.
