Double-scale precision fixed-speed quantitative regulator for infusion

Abstract

The invention discloses a dual-scale precision fixed-speed and quantitative regulator for infusion, which comprises a fixed base, a liquid inlet and a liquid outlet are arranged under the fixed base, a movable flow rate adjustment plate is fixed above the fixed base, and the fixed base and the flow rate adjustment plate There is a sealing pad between them, and the sealing pad is provided with through holes corresponding to the liquid inlet and the liquid outlet; the flow rate adjustment plate is provided with liquid flow channels of different apertures, and the liquid inlet and the liquid outlet are connected through the liquid flow channel; There is a flow rate mark on the device, and the flow rate mark is composed of a dial and a corresponding flow rate indicator. The device of the present invention, by changing the size of the liquid channel, realizes accurate, fast and stable control of the infusion flow rate and flow rate, and at the same time, it is intuitive and convenient to read the infusion flow rate and infusion flow rate, and is convenient for one-handed operation, which conforms to various clinical usage habits, various The application environment ensures the safety of infusion. Especially when the condition of ordinary patients suddenly deteriorates, it can quickly meet the urgent needs of transforming infusion into precise control, and win the opportunity for rescue.

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 operation of the infusion pump is too complicated and not intuitive enough
