Abstract

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.

Description

technical field [0001] The invention relates to a medical device, in particular to a flow rate regulator for transfusion. Background technique [0002] Flow rate control during infusion is very important. A reasonable flow rate can help improve efficacy and reduce risks during infusion. In clinical practice, doctor’s orders are usually issued at the rate of drops, and when the condition is serious or there are special needs, they will be issued at the flow rate. Special medication requires the flow rate to be as accurate as “drips”. In particular, when infusion is performed on cardiac insufficiency, children, newborns, elderly patients, and critically ill patients, if the infusion speed is too fast, too much fluid enters the body per unit time or the drug dose is too large, it will induce heart failure and excessive drop in blood pressure. Waiting fast makes the patient's condition worse. If the infusion speed is too slow, the fluid entering the body per unit time is insuf...
