In various gravity or pressure intravenous infusion processes, such as using a high-pressure syringe to inject contrast media into the human body, the usual injection speed is 2-4 ml per second, especially during perfusion, the general injection speed is 6 ml per second , even up to 8 ml per second, such a fast injection speed will generate greater pressure on the blood vessel wall, which will easily cause vascular damage and local pain in patients, especially for patients with repeated intravenous injections. It is necessary to improve the existing indwelling needle for intravenous infusion due to the pain at the site and the damage of the blood vessel wall.
