Abstract

The invention discloses a power-assisted three-ring injection syringe which comprises a syringe main body and a spiral pushing rod, wherein the syringe main body comprises a tail end and a near end; the spiral pushing rod comprises a tail end and a near end; the tail end of the spiral pushing rod is connected with a rubber stopper and is inserted into the syringe main body; the near end of the spiral pushing rod is sheathed with an inner sleeve; a nut, which is matched with the inner sleeve, is sheathed on the syringe main body; a double-ring sleeve is sheathed outside the inner sleeve and is connected with the inner sleeve; a first spring is sheathed on the spiral pushing rod and is sealed by the inner sleeve; a second spring is sealed by the double-ring sleeve and the inner sleeve; and a locking part, which is used for clamping the spiral pushing rod, is arranged on the inner sleeve. By the power-assisted three-ring injection syringe, the flow rate and the flow quantity required for the radiography can be easily achieved; and therefore, the power-assisted three-ring injection syringe is very convenient for operators to operate.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a power-assisted three-ring syringe. Background technique [0002] Angiography is a method used to image the structures of the cardiovascular system, diagnose it, and examine the response to treatment. During angiography, a doctor inserts a catheter through the patient's body and injects a contrast medium through the catheter into the blood vessels of the patient being examined. At the same time, an X-ray machine is used to image the area in the patient's body injected with contrast material, and the radiation beam will pass through the patient's tissue and will be absorbed by the contrast material. Therefore, under fluoroscopy, the development of the contrast agent in the blood vessel can be clearly seen, that is, the development of the inner diameter of the blood vessel. The image of the vessel is displayed on a monitor and recorded. [0003] Contrast imaging is a necessary me...
