Problems solved by technology

[0003] The present invention aims at the technology of manually adjusting the flow regulator carried by the infusion set itself or relying on the existing flow rate control device of the infusion set to adjust the flow rate of the liquid when the disposable infusion set is used in the market to infuse the patient. Can not be designed for the problem of accurate control of the flow rate of the liquid medicine in the disposable infusion set, the purpose of the present invention is to provide a common infusion set with low cost and to control the infusion set outside the infusion set hose. Infusion set medical liquid flow rate control device that can accurately control the flow rate of the liquid medicine

Embodiment 1

[0024] As shown in Figures 1-4, the present embodiment includes a casing 2, which includes a cavity with a motor 12 and a control instrument 1 connected to the motor 12 through a wire 11 fixed on the casing 2. There is a bracket on the outside of the cavity, and the flow booster 6 is installed on the bracket. The flow pusher 6 includes two rotating shafts, one of which is connected to the motor 12 . Crawler belts are installed on the rotating shaft, and a group of rollers 5 are installed on the crawler belts through shaft intervals. A pressure plate 7 is installed on the casing 2 on the same side as the two rotating shafts above the pusher 6. One end of the pressing plate 7 is connected with the casing 2 through a positioning shaft 8 parallel to the rotating shaft, and the other end is matched with the lower end of the spring 4. The upper end of the spring 4 It is fixed on the plate body fixedly connected with the casing 2. A tube clip 10 is provided on one side of the casin...

Embodiment 2

[0027] As shown in Figures 5-8, this embodiment includes a casing 2, and the casing 2 includes a cavity with a bracket outside the cavity on which a flow booster 6 is installed. The flow mover 6 includes a circular support with a rotating shaft, a group of rollers 5 are installed at intervals through the shaft in the groove on the side of the support, and a pressing plate 7 is installed on the casing 2 above the flow mover 6 . The part corresponding to the flow booster 6 on the lower surface of the pressing plate 7 is arc-shaped, its curvature is smaller than that of the circular support, and its span is greater than the diameter of the circular support. One end of the pressing plate 7 is connected with the casing 2 through a shaft parallel to the rotating shaft, and the other end cooperates with the lower end of the spring 4 , and the upper end of the spring 4 is fixed on the plate body fixedly connected with the casing 2 . A tube clip 10 is provided on one side of the casing...

Embodiment 3

[0029] As shown in Figures 9 and 10, the embodiment includes a casing 2, on which there is a bracket on which a flow booster 6 is installed, and the structure of the flow booster 6 is the same as that of the first embodiment. Positioning chute 14 is fixed on the casing 2 on flow booster 6 one side, and slide block is housed in the groove, and the slide block top cooperates with spring, and the upper end of spring is connected with the plate body that is fixed on the casing. Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The medicine liquid flow rate controller for infusion set includes one casing, one flow pushing device on the casing and with roller, one extruding mechanism matching with the roller in the flow pushing device and mounted on to the casing via a locator for being parallel to the roller, and one elastic unit fixed on the casing and connected to the movable part of the extruding mechanism. The present invention has the features of simple operation, accurate metering, simple structure and low manufacture cost.

Description

technical field [0001] The invention relates to a device for controlling the liquid flow rate of an infusion set. Background technique [0002] Intravenous infusion is one of the most commonly used clinical treatment methods, and it is a common drug administration technique in the nursing profession. Clinically, the appropriate infusion speed is matched according to the different drugs and patient conditions. Some special patients or special drugs in the hospital must require a small amount of low-speed accurate infusion, otherwise, if the infusion is too fast, it may cause poisoning, and in more severe cases, edema and heart failure may occur; if the infusion is too slow, the dose may not be enough , compromising treatment and placing an unnecessary burden on patients and care. Routine clinical infusion, generally adopts disposable infusion device hanging bottle infusion, and observes with eyes, relies on regulating the flow regulator to control the speed of medicine drip...
