[0006] Furthermore, the extrusion and pushing assembly includes a sliding column, a column head slider, a long connecting rod, a short connecting rod, a double-headed motor, an assisting slider and a round block. Two straight grooves are provided in the rod body. The assisting slider and the column head slider are respectively slidably arranged in the two straight grooves. The round block is rotatably arranged in the assisting slider. The sliding column is fixedly connected to the round block. The sliding column is rotatably connected to the column head slider. The double-headed motor is fixedly arranged on the rod body. The short connecting rod is fixedly arranged on the output end of the double-headed motor. The long connecting rod is hinged between the short connecting rod and the column head round block.

[0007] Furthermore, the extrusion and pushing assembly also includes an elastic rope, a fixed magnet and an electromagnet, the elastic rope is fixedly arranged between the round block and the assisting slider, the fixed magnet is fixedly arranged on the round block, the electromagnet is fixedly arranged on the assisting slider, and the electromagnet is magnetically connected to the fixed magnet.

[0008] Furthermore, the squeezing and pushing assembly also includes a plurality of balls, a plurality of the balls are linearly arrayed and rollingly engaged on the sliding column, and a plurality of the balls are rollingly engaged on the hose.

[0009] Furthermore, a bracket is fixedly provided on the rod body, and the bracket is fixedly connected to the medicine bottle.

[0010] Furthermore, an injection tube is fixedly provided at one end of the rod body, and the injection tube is connected to the hose.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present invention arranges a sliding column parallel to the hose on the rod body, and through the coordinated use of components such as a double-headed motor, a long connecting rod, and a short connecting rod, the contrast agent in the hose can be pushed by the ball on one side of the sliding column to achieve the effect of promoting the injection of the contrast agent.

[0013] 2. The present invention uses a round block, a fixed magnet, an electromagnet and an elastic rope in combination, so that the ball on the sliding column can rotate relative to the axis of the sliding column. Therefore, when the sliding column moves back and forth linearly with respect to the contrast agent in the hose when the double-headed motor drives the sliding column, the ball is controlled to rotate to the top of the rod body and not to contact the hose, thereby avoiding the backflow of the contrast agent caused by the return movement of the ball and the sliding column.

[0024] like Figure 1 to Figure 6 As shown, a clinical angiography injection device for cardiovascular medicine includes a rod body 1, a medicine bottle 3, a hose 4 and a squeezing and pushing assembly 7. The medicine bottle 3 is located above the rod body 1, the hose 4 is fixed to the bottom of the medicine bottle 3, the hose 4 is connected to the medicine bottle 3, and the squeezing and pushing assembly 7 is arranged on the rod body 1.

[0025] like Figure 1 to Figure 6As shown, the extrusion and pushing assembly 7 includes a sliding column 701, a column head slider 703, a long connecting rod 704, a short connecting rod 705, a double-headed motor 706, an assisting slider 707 and a round block 708. Two straight grooves 101 are provided in the rod body 1. The assisting slider 707 and the column head slider 703 are respectively slidably arranged in the two straight grooves 101. The round block 708 is rotatably arranged in the assisting slider 707. The sliding column 701 is fixedly connected to the round block 708. The sliding column 701 is rotatably connected to the column head slider 703. The double-headed motor 706 is fixedly arranged on the rod body 1. The short connecting rod 705 is fixedly arranged on the output end of the double-headed motor 706. The long connecting rod 704 is hinged between the short connecting rod 705 and the column head round block 708.

[0026] like Figure 1 to Figure 6 As shown, the extrusion and pushing assembly 7 also includes an elastic rope 709, a fixed magnet 710 and an electromagnet 711. The elastic rope 709 is fixed between the round block 708 and the assisting slider 707. The fixed magnet 710 is fixed on the round block 708. The electromagnet 711 is fixed on the assisting slider 707. The electromagnet 711 is magnetically connected to the fixed magnet 710.

[0027] like Figure 1 to Figure 6 As shown, the squeezing and pushing assembly 7 further includes a plurality of balls 702 , which are linearly arrayed and rollingly engaged on the sliding column 701 , and are rollingly engaged on the hose 4 .

[0028] like Figure 1 to Figure 6 As shown, a bracket 2 is fixedly provided on the rod body 1 , and the bracket 2 is fixedly connected to the medicine bottle 3 .

[0029] like Figure 1 to Figure 6 As shown, an injection tube 5 is fixedly provided at one end of the rod body 1 , and the injection tube 5 is connected to the hose 4 .

[0030] like Figure 1 to Figure 6 As shown, a handle 6 is fixedly provided at the bottom end of the rod body 1.

[0031] When in use, the doctor holds the device by the handle 6, connects the needle through the injection tube 5 and injects the contrast agent into the patient's body. The contrast agent flows from the medicine bottle 3 into the hose 4, and flows into the patient's body through the injection tube 5.

[0032] During the contrast medium injection process, in order to enhance the fluidity of the contrast medium, the double-headed motor 706 is started. The double-headed motor 706 drives the column head slider 703, the sliding column 701, and the assisting slider 707 to slide back and forth along the straight groove 101 through the short connecting rod 705 and the long connecting rod 704. When the sliding column 701 slides toward the injection tube 5, the ball 702 contacts the hose 4 below, and at the same time squeezes the hose 4, causing the contrast medium in the hose 4 to flow out quickly.

[0033] When the movement direction of the sliding column 701 is opposite to the flow direction of the contrast agent, in order to prevent the double-headed motor 706 from driving the sliding column 701 and the ball 702 to push the contrast agent to flow backward, the electromagnet 711 is temporarily powered off to interrupt the magnetic attraction relationship with the fixed magnet 710. The round block 708 rotates under the pulling force of the elastic rope 709, and at the same time drives the sliding column 701 and the ball 702 to rotate relative to the axis direction of the sliding column 701, so that the sliding column 701 will not drive the contrast agent in the hose 4 to flow backward during the resetting process.

[0034] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
