As shown in fig. 1 and 2, an infusion needle with a filtering function comprises an infusion tube, wherein the infusion tube is divided into a first infusion part 1 and a second infusion part 2, and the first infusion part 1 is connected with the second infusion part 2 through a filtering unit;

the filtering unit comprises a mounting sleeve 30, an upper connecting port 31 and a lower connecting port 32 are arranged on the mounting sleeve 30, the upper connecting port 31 is detachably connected with the first transfusion part 1, and the lower connecting port 32 is detachably connected with the second transfusion part 2; as for the detachable connection, in the present embodiment, a plug-in type, a screw connection type, or the like may be employed.

The filter plates 33 are held between the filter plates 33, and the filter plates 33 are engaged with the mounting sleeve 30, so that the inner cavity of the mounting sleeve 30 is divided into a first inner cavity adjacent to the upper connection port 31 and a second inner cavity adjacent to the lower connection port 32, with the filter plates 33 as a boundary.

When the infusion bottle is used, the infusion liquid extracted by the second infusion part 2 is filtered by the filter plate 33 and the filter paper 34, so that the situation that a needle head of the second infusion part 2 is inserted into the liquid storage bottle, and a part of a leather plug enters the needle head and enters the human body along with the infusion liquid is avoided.

In the present embodiment, the upper connection port 31 and the lower connection port 32 are on the same axis.

In this embodiment, the second inner cavity is provided with a temporary storage 35, and the second inner cavity is provided with a toggle assembly, when the filter plate 33 is adhered with a plug, the toggle unit moves the plug out from the flow channel formed by the upper connector 31 and the lower connector 32 to the temporary storage 35, so as to avoid influencing the infusion extraction.
