Background
During the use of the high-pressure syringe, the doctor needs to suck the contrast medium and the physiological saline into the syringe through the puncture outfit or the drug suction tube, but the drug is sucked while a lot of air is introduced, so that the front end part of the syringe is actually filled with air when the drug suction is completed. After replacing the connecting tube, the doctor needs to manually press the button on the injection head of the high-pressure injector to exhaust air, so as to discharge air at the front end of the syringe and make the liquid fill the connecting tube.

At present, a high-pressure injector has a key for manually controlling the piston to advance and retreat on an injection head, when exhausting, a doctor needs to rotate the injection head upwards, press a piston advancing key on a corresponding side, and observe liquid level movement, taking fig. 1 (a side is contrast medium, and B side is physiological saline) as an example: (1) Firstly, pressing the piston advancing key on the A side to gradually discharge the air in the syringe on the A side, and moving the liquid level to the junction of the connecting pipes A and B. In order to save contrast agent, the main line after a, B summing is filled with saline. (2) And then the piston advancing key on the B side is pressed down, so that the air in the needle cylinder on the B side is gradually discharged and passes through the joint of the A pipeline and the B pipeline, and the whole connecting pipe is filled. (3) In order to accelerate the exhaust speed, doctors can control the exhaust speed through different keys. Generally, when the liquid level is far away from the front end of the syringe, the liquid level is used at a higher speed, and when the liquid level is near the front end of the syringe, the liquid level is used at a lower speed to prevent the liquid from flowing out.
