DETAILED DESCRIPTION

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] Please refer to Figure 1 The embodiment provides a high-pressure syringe extension tube clamping structure, which is installed on the high-pressure syringe and is used to fix the extension tube 80, reduce the labor intensity of medical staff, and simplify the operation process of medical staff. The high-pressure syringe extension tube clamping structure of the embodiment includes a mounting plate 10, and a first clamp 20, a second clamp 30 and a third clamp 40 arranged on the mounting plate 10.

[0030] The mounting plate 10 includes a fixing side 11 and a mounting side 12. The fixing side 11 is used to be fixed on the high-pressure injector, and the fixing methods include but are not limited to bonding, bolting, etc. The mounting side 12 is used to install the first buckle 20, the second buckle 30 and the third buckle 40, which are arranged in a straight line and are all provided with a slot 50. At the same time, the slots 50 of the first buckle 20, the second buckle 30 and the third buckle 40 are also arranged in a straight line.

[0031] Please refer to Figure 2 The first clip 20 and the third clip 40 are connected to the mounting plate 10 in the same manner. Both the first clip 20 and the third clip 40 include a clip joint 51 and a connecting rod 52. A clip groove 50 is provided on one side of the clip joint 51. The other side of the clip joint 51 is fixedly connected to the connecting rod 52. The connecting rod 52 extends into the mounting plate 10 and is connected to the mounting plate 10. There are two ways to connect the connecting rod 52 to the mounting plate 10. The first way is to fix the connecting rod 52 to the mounting plate 10, such as by interference fit, bolt connection, etc. Please refer to Figure 5 At this time, the cross-sectional shape of the connecting rod 52 is non-circular to prevent the connecting rod 52 from loosening; the second is that the connecting rod 52 is rotatably connected to the mounting plate 10, please refer to Figure 6 At this time, the cross-sectional shape of the connecting rod 52 is circular. In order to ensure that the connecting rod 52 and the mounting plate 10 will not fall off, a hemispherical block 53 is connected to the connecting rod 52 and is engaged with the mounting plate 10.

[0032] Please refer to Figure 3 and Figure 4 The second buckle 30 also includes a buckle joint 51 and a connecting rod 52. A buckle groove 50 is also provided on one side of the buckle joint 51. The other side of the buckle joint 51 is fixedly connected to the connecting rod 52. The connecting rod 52 of the second buckle 30 is connected to the mounting plate 10 through a sliding assembly 60, so that the second buckle 30 can slide on the mounting plate 10. Moreover, the sliding direction of the second buckle 30 intersects with the connecting direction of the first buckle 20 and the third buckle 40. After the second buckle 30 slides, the first buckle 20, the second buckle 30 and the third buckle 40 are distributed in a triangle.

[0033] In this embodiment, the sliding direction of the second buckle 30 is perpendicular to the connecting direction of the first buckle 20 and the third buckle 40, thereby reducing the influence of the bending of the extension tube 80 on the flow rate of the contrast agent and the physiological saline.

[0034] The mounting plate 10 is provided with a slide groove from the mounting side 12, and the slide groove includes a guide slide groove 13 and a limiting slide groove 14. The guide slide groove 13 is arranged inside the mounting plate 10 along the sliding direction of the second buckle 30, one side of the limiting slide groove 14 is connected to the guide slide groove 13, and the other side of the limiting slide groove 14 extends to the mounting side 12. The overall cross-section of the guide slide groove 13 and the limiting slide groove 14 is T-shaped, and the width of the guide slide groove 13 is greater than the width of the limiting slide groove 14.

[0035] The sliding assembly 60 includes a slider 61, a first spring 62, and a second spring 63. The slider 61 includes a guide slider 64 and a limit slider 65 connected to each other. The guide slider 64 is located in the guide slide groove 13 and slides with the guide slide groove 13. The limit slider 65 is located in the limit slide groove 14 and slides with the limit slide groove 14. The two ends of the first spring 62 are respectively fixedly connected to the guide slider 64 and the end wall of the guide slide groove 13, which are used to reset and support the slider 61, so as to facilitate the sliding of the slider 61. The connecting rod 52 of the second buckle 30 extends into the limit slider 65 and slides with the limit slider 65. The two ends of the second spring 63 are respectively fixedly connected to the connecting rod 52 of the second buckle 30 and the guide slider 64, which are used to reset and support the second buckle 30.

[0036] In order to make the second buckle 30 stay at the designated position after sliding, in this embodiment, the connecting rod 52 of the second buckle 30 is connected to the side wall of the limiting slide groove 14 through a positioning mechanism. The positioning mechanism includes a limiting block 71 arranged on the outside of the connecting rod 52 of the second buckle 30, and a plurality of positioning blocks 72 evenly spaced along the extending direction of the limiting slide groove 14, and the limiting block 71 extends between two adjacent positioning blocks 72 to fix the second buckle 30. In order to facilitate the extension of the limiting block 71, one end of the limiting block 71 used to extend between two adjacent positioning blocks 72 and one end of the block 72 used for the limiting block 71 to extend are both tapered.

[0037] In this embodiment, the cross section of the clamping groove 50 is arc-shaped, the arc shape is adapted to the outer diameter of the extension tube 80 , and the central angle corresponding to the arc shape is greater than 180°.

[0038] When the high-pressure syringe extension tube clamping structure of this embodiment is used, first press the second clamp 30, slide the second clamp 30 to the designated position, and then release the second clamp 30; then clamp the extension tube 80 into the clamping groove 50 of the first clamp 20, the second clamp 30 and the third clamp 40 in sequence, and then fix the extension tube 80. The whole fixing process is convenient and fast. Obviously, the extension tube 80 can also be clamped into the clamping groove 50 of the first clamp 20, the second clamp 30 and the third clamp 40 in sequence, and then the second clamp 30 is slid to the designated position. At this time, due to the existence of friction, the movement process is not as smooth as the above process.

[0039] The present embodiment also discloses a high-pressure syringe, comprising a high-pressure syringe body, an extension tube 80 and the above-mentioned high-pressure syringe extension tube clamping structure; the extension tube 80 is connected to the high-pressure syringe body and is clamped in the clamping groove 50 of the first clamp 20, the second clamp 30 and the third clamp 40; the fixed side 11 is connected to the high-pressure syringe body.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
