| titleOfInvention | Anti-backflow connecting pipe of injector |
| abstract | The utility model discloses a syringe backflow-preventing connecting pipe, which comprises a first pipeline connected on a contrast agent barrel, a second pipeline connected on a physiological saline barrel and a third pipeline connected with an indwelling needle, wherein the first pipeline and the second pipeline are both connected on the third pipeline through a check valve mechanism, and the check valve mechanism is also arranged at the connecting part of the third pipeline and the indwelling needle; the check valve mechanism comprises water inlet pipes which are respectively arranged on the first pipeline, the second pipeline and the third pipeline, the water inlet pipes are connected with water outlet pipes through valve bodies, the water outlet pipes are sequentially arranged at two ends of the third pipeline and on the indwelling needle pipeline, and telescopic valves which are used for sealing the water inlet pipes and the water outlet pipes and preventing fluid from flowing back are arranged on the valve bodies. Utility model installs three one-way flow valve in the tee bend pipe, need not manual can realize the sealing to the interior liquid refluence of pipeline, comparatively labour saving and time saving when using. |
