DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1A safe precision filtering infusion device comprises an infusion tube 1, one side of the infusion tube 1 is fixedly connected with a filter tube 2, a drip bucket 3 and a puncture needle 4, and the other side of the infusion tube 1 is fixedly connected with a flow stopper 6 for preventing the outflow of the drug solution.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1 and Figure 4 The flow stop part 6 includes a baffle A61 fixedly connected to the other side of the infusion tube 1, a water outlet hole A62 is provided on the outer surface of the baffle A61, a baffle B63 is rotatably connected to one side of the baffle A61, a water outlet hole B64 is provided on the outer surface of the baffle B63, a rotating rod 65 is fixedly connected to one side of the baffle B63, the baffle B63 is rotatably connected to the infusion tube 1, a squeezing ball 21 is fixedly connected to one side of the filter tube 2, and a filter A is fixedly connected to the inner wall of the filter tube 2.

[0025] Specifically, when it is necessary to remove the residual air inside the infusion tube 1, rotate the rotating rod 65 to make the baffle B63 rotate accordingly, so that the water outlet A62 and the water outlet B64 are misaligned, and the baffle A61 and the baffle B63 cover the water outlet A62 and the water outlet B64 from each other to prevent the medicine from flowing out with the change of air pressure when the air is discharged, thereby reducing the waste of the medicine. After the air is emptied, the puncture needle 4 punctures the skin and connects with the vein for infusion. The filter A can filter and purify the external gas entering the infusion tube 1. When it is necessary to discharge the air inside the infusion tube 1, squeeze the squeezing ball 21 and the infusion tube 1 to change the internal air pressure of the infusion tube 1 and discharge the internal gas.

[0026] Embodiment 2:

[0027] See also Figure 1-Figure 3 The lower end of the infusion tube 1 is fixedly connected to a dosing tube 9, and a sealing gasket 91 is movably connected to one side of the dosing tube 9. A flow regulator 8, a fixed shaft 7 and an infusion needle 5 are fixedly connected to one side of the infusion tube 1. A mounting block 71 is rotatably connected to one side of the fixed shaft 7. A filter screen B72 is movably connected to the inner wall of the mounting block 71. A rotating groove 13 is provided on one side of the infusion tube 1. The mounting block 71 is movably connected to the infusion tube 1 through the rotating groove 13. An interface A11 is provided on one side of the infusion tube 1. The filter tube 2 is connected to the infusion tube 1 through the interface A11. An interface B12 is provided on the other side of the infusion tube 1.
