Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of syringe connection component devices, in particular to a connection component for a high-pressure syringe. Background Art
[0002] High-pressure injectors, as auxiliary equipment in radiological diagnosis and treatment systems, have gradually entered clinical use with the development of technologies such as X-rays, rapid film changers, image intensifiers, and artificial contrast agents. Their basic function is to quickly and accurately inject a sufficient amount of high-concentration X-ray contrast agent into the examination site over a specified period of time through percutaneous puncture into a blood vessel or through existing orifices in the body, enabling diagnostic imaging and treatment of lesions.
[0003] Most high-pressure injectors require the assistance of other devices when in use, and often have no place to place or store them when in use. Most of them are controlled devices, including but not limited to spare syringe tips and other parts.
[0004] Nowadays, the front end of most high-pressure syringes is only installed by the high-pressure syringe end, and there is a lack of corresponding connecting components on the side. Some connecting components themselves do not have a stable effect, and are relatively weak when targeting circular tube-type instruments. Subsequent treatment of patients may be slightly cumbersome and may also affect the continuity of the operation. In addition, most connecting components are in a fixed effect and cannot be rotated to change their original position. Since the design of the connecting components is to facilitate subsequent treatment operations, the above phenomenon will have an adverse effect on the treatment process. Utility Model Content
[0005] The purpose of the present utility model is to provide a connection assembly for a high-pressure injector to solve the problems raised in the above background technology.

[0021] Figure 1 This is an overview of the front of the device. The main body is a control chassis 1. A connection port is provided at the front end of the control chassis 1, and a high-pressure syringe 4 is inserted into the upper end of the connection port. At the same time, an injection port is assembled at the front end of the high-pressure syringe 4. An external frame 3 is mounted on the surface of the high-pressure syringe 4. The external frame 3 is embedded in the outer surface of the high-pressure syringe 4, and an inner recessed groove is provided inside the external frame 3. At the same time, a slider 2 is assembled on the inner recessed groove. The slider 2 adopts a curved surface design and is embedded in the upper and lower recessed grooves. A bearing plate 5 is assembled on the surface of the slider 2, and a notch is provided on the surface of the bearing plate 5. Fixing bolts are assembled on the surface of the notch to fix the bearing plate 5.
[0022] Figure 2 This is an overview of the back of the device. The main body is a control chassis 1. A connection port is provided on the lower surface of the control chassis 1. The installation of the connection port is convenient for connection during certain power usage periods, and wiring is convenient. A control panel is provided on the side surface of the control chassis 1. At the same time, control buttons are assembled on the upper end of the control panel. The upper end of the external frame 3 is equipped with a convex edge. The convex edge bulges outward, leaving a gap inside, and a connecting block 9 is assembled on the side surface of the bearing plate 5. At the same time, a fixing frame 8 is installed on the surface of the connecting block 9. A movable column 6 is inserted inside the fixed frame 8, and a return spring 10 is assembled on the surface of the movable column 6. At the same time, an embedded block 7 is assembled on both sides of the movable column 6. The front end of the embedded block 7 is designed according to the gap inside the convex edge, and a pressing block is provided on the rear surface. The design of the return spring 10 allows the embedded block 7 to be embedded in the gap at any time, thereby stabilizing the bearing plate 5 and indirectly fixing the bearing plate 5 to maintain this angle.
[0023] Figure 3 This is a side overview of the device. The main body is a carrying plate 5. A connecting frame 14 is provided at the upper end of the carrying plate 5, and an insertion port is provided on the surface of the connecting frame 14.

The design of the active blocking block 12 presents an internal empty state, and the front end position of the spiral column 15 has no spiral pattern, but is connected by a disc, and the disc is embedded in the interior of the active blocking block 12. By utilizing the moving trajectory of the pressure block 17 at the position of the telescopic column 13 installed on the side, the spiral column 15 engages with the spiral pattern of the interlaced layer of the connecting frame 14, and pushes forward or backward to provide an inward pressure effect.
