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

Embodiment 1

[0076] Double-scale precise constant speed and quantitative regulator for infusion, including a fixed base 1, a liquid inlet 11 and a liquid outlet 12 are arranged under the fixed base 1, a fixed shaft extends upward from the middle of the fixed base 1, and a side wall extends upward from the edge. There are upper and lower buckles 5 on the shaft and the side wall, and the movable flow rate adjustment plate 2 is fixed through the buckle 5; the cut-off card position and the gasket 4 are located between the fixed base 1 and the flow rate adjustment plate 2; the fixed base 1 There are main liquid inlet tanks 211 and main liquid outlet tanks 213 respectively connected to the liquid inlet 11 and the liquid outlet 12, wherein the main liquid inlet tank 211 is radially extended and distributed with speed regulating grooves 212 of different apertures. , the speed regulating groove 212 communicates with one end of the groove 41 on the gasket 4, and the other end of the groove 41 on the ...

Embodiment 2

[0083] refer to Figure 5-8 , the structure of the regulator is basically the same as in Example 1, the difference is that the realization of the flow rate adjustment is different, and the setting of the support plate is also changed accordingly:

[0084] The flow rate adjustment plate 2 is provided with a liquid inlet 11, the fixed base 1 is provided with a liquid outlet 12, and the flow rate adjustment plate 2 is provided with a flow rate adjustment channel. The flow rate adjustment channel is composed of a main groove 211 and speed-regulating recesses of different apertures communicated with the main groove. The main groove 211 is connected with the liquid inlet 11, the other end of the speed regulating groove 212 is connected with the through hole on the gasket 4, and the other end of the through hole on the gasket 4 is connected with the liquid outlet 12 of the fixed base 1. In communication, the gasket 4 is fixed on the fixed base 1 through the positioning column 14 prov...

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 a channel connecting the liquid inlet and the liquid outlet, and the channels of different apertures are used to realize the regulation of the infusion flow rate; the regulator is provided with a flow rate mark, and the flow rate mark is determined by the dial and the corresponding Composition of 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...
