The invention discloses a double-scale accurate constant-speed quantitative regulator for infusion. The regulator comprises a fixed base. The lower portion of the fixed base is provided with a liquid inlet and a liquid outlet. A movable flow rate regulating plate is fixed to the position above the fixed base. A sealing gasket is arranged between the fixed base and the flow rate regulating plate. The sealing gasket is provided with through holes corresponding to the liquid inlet and the liquid outlet. The flow rate regulating plate is provided with liquid flow channels with different bore diameters. The liquid inlet and the liquid outlet are communicated through the liquid flow channels. The regulator is further provided with a flow rate identifier. The flow rate identifier is composed of a dial and a corresponding flow rate indicator. According to the double-scale accurate constant-speed quantitative regulator for infusion, by changing the sizes of the liquid flow channels, accurate, quick and stable control over the infusion flow rate and the infusion flow volume is realized meanwhile, the infusion flow rate and the infusion flow volume are read visually and conveniently, one-hand operation is facilitated, multiple clinical use habits and multiple application environments are conformed to, and infusion safety is guaranteed particularly, when the state of an illness of a common patient deteriorates suddenly, the emergency demand that infusion is controlled accurately can be met quickly, and rescue time is won.本發明之輸液用雙刻度精準定速定量調節器,包括固定底座,其下方設有進液口和出液口,其上方固定有可動的流速調節板,固定底座和流速調節板之間設有密封墊,其上設有對應於進液口和出液口的通孔;流速調節板設有不同孔徑的液流通道,進液口和出液口通過液流通道連通;調節器上設有由刻度盤和對應的流速指示器組成的流速標識。本發明裝置,通過改變液體通道的大小,實現對輸液流速、流量的控制精確、快速、穩定,同時直觀方便閱讀輸液流速和輸液流量,方便單手操作,符合臨床多種使用習慣、多種應用環境,保證輸液安全。特別在普通病人病情突然惡化時,快速滿足輸液轉變為精準控制的緊急需求,贏取搶救時機。1‧‧‧固定底座11‧‧‧進液口12‧‧‧出液口13‧‧‧定位底盤14‧‧‧密封墊定位柱2‧‧‧流速調節板21‧‧‧液流通道22‧‧‧滅菌用通孔23‧‧‧定位動盤24‧‧‧定位塊25‧‧‧上護緣26‧‧‧下護緣31‧‧‧刻度盤4‧‧‧密封墊5‧‧‧卡扣結構
