[0003] Existing disposable infusion pumps usually have a three-way valve on the catheter as a dosing valve. When dosing from one end of the three-way valve, the drug solution will flow out from both ends of the three-way valve, and the drug solution may flow into the catheters at the other two ends of the three-way valve. When the infusion is performed, the pressure during the infusion will affect the normal infusion work.
[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0010] The utility model is further configured as follows: a flow guide port is opened on the side wall of the flow limiting tube facing the first flow guide tube.
[0011] The utility model is further configured as follows: a thread is arranged at the bottom of the side wall of the valve body, and a protective cap is threadedly connected thereto.
[0012] The utility model is further configured as follows: the second connecting pipe is connected with an adjustable filter.
[0013] The utility model has the following beneficial effects: by setting a dosing flow limiting component, when adding medicine, it can prevent the medicine liquid from flowing into and out through the second connecting pipe, ensuring that the medicine can fully flow into the liquid storage device from the first connecting pipe, and can add medicine through the dosing valve at the same time as adding medicine, without affecting the patient's infusion.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0020] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0021] As shown in the figure, a disposable infusion pump convenient for drug addition comprises a protective bottle 1, a liquid storage device 2 is arranged in the protective bottle 1 and is connected to a first conduit 3, a drug addition valve 4 is connected to the end of the first conduit 3, the drug addition valve 4 comprises a valve body 5 arranged in a tubular shape, a first connecting pipe 6 connected to the first conduit 3 is arranged on one side of the valve body, a second connecting pipe 7 is arranged on the other side, and a drug addition flow limiting component is arranged in the valve body 5; when adding medicine, when the drug liquid is added from the top of the valve body 5, when the drug addition flow limiting component is used, the drug liquid enters the liquid storage device 2 from the first connecting pipe 6.
[0022] By setting up a dosing flow limiting component, when adding medicine, it is possible to prevent the drug liquid from flowing into and out through the second connecting tube 7, ensuring that the medicine can fully flow into the liquid storage device 2 from the first connecting tube 6, and can add medicine through the dosing valve 4 at the same time without affecting the patient's infusion.
[0023] The dosing flow limiting component includes a flow limiting tube 8 slidably connected to the valve body 5, and a baffle plate 9 is provided at the bottom end of the flow limiting tube 8 on one side of the second connecting tube 7, and also includes a control component for controlling the flow limiting tube 8 to slide in the valve body 5, and the control component controls the flow limiting tube 8 to descend and blocks the second connecting tube 7. A baffle plate 10 is provided at the bottom of the flow limiting tube 8, and the control component includes a spring 11 provided inside the valve body 5, and both ends of the spring 11 are fixedly connected to the lower surface of the baffle plate 10 and the bottom inner wall of the valve body 5. A flow guide port 12 is opened on the side wall of the flow limiting tube 8 facing the first flow guide tube.
