Double-scale accurate constant-speed and quantitative regulator for transfusion

Abstract

The invention discloses a double-scale accurate constant-speed and quantitative regulator for transfusion. The regulator comprises a fixed base; a liquid inlet and a liquid outlet are formed below the fixed base; a movable flow speed adjusting plate is fixed above the fixed base; a seal gasket is arranged between the fixed base and the flow speed adjusting plate; a passage communicated with the liquid inlet and the liquid outlet is formed in the seal gasket; the transfusion flow speed regulation is achieved by using passages of different pore diameters; a flow speed identification is arranged on the regulator, and comprises a dial and a corresponding flow speed indicator. According to the regulator, through the change of the liquid passage, the transfusion flow speed and flow are accurately, quickly and stably controlled, meanwhile, the transfusion flow speed and the transfusion flow are conveniently and intuitively read, the single hand operation is facilitated, the regulator meets various clinical use habits and various application environments, and the transfusion safety is ensured. When the state of an illness of a common patient deteriorates suddenly, the urgent requirement of accurate control of transfusion is quickly met, and the aid time is gained.

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...

Problems solved by technology

It cannot be applied when precise control of flow rate regulation is required

[0005] Infusion pumps are commonly used when precise control of the infusion flow rate is required, but the infusion pumps are expensive, unfavorable for popularization, and the operation is too complicated, not intuitive and simple enough, especially when the condition of ordinary patients changes suddenly, it takes time to install and debug before they can be put into use
