In a preferred embodiment of the invention, the liquid passing area comprises a first liquid passing hole and a second liquid passing hole which are arranged at intervals, the puncturing part is inserted into the penicillin bottle so that the first liquid passing hole is positioned outside the penicillin bottle, and the second liquid passing hole is positioned inside the penicillin bottle.
In a preferred embodiment of the present invention, the first liquid through hole and the second liquid through hole are coaxially arranged.
In a preferred embodiment of the present invention, the first liquid through holes and the second liquid through holes are staggered in the axial direction.
In a preferred embodiment of the invention, the liquid passing area comprises a first liquid passing hole and a second liquid passing hole, parts of the first liquid passing hole and the second liquid passing hole are overlapped, the puncturing part is inserted into the penicillin bottle, so that the part of the first liquid passing hole is positioned outside the penicillin bottle, and the rest part of the first liquid passing hole and the second liquid passing hole are positioned inside the penicillin bottle.
In a preferred embodiment of the present invention, the first liquid through hole and the second liquid through hole are coaxially overlapped.
In a preferred embodiment of the present invention, the first liquid passing hole and the second liquid passing hole are overlapped by parts staggered in the axial direction.
In a preferred embodiment of the present invention, the size of the first liquid through hole is smaller than that of the second liquid through hole.
In a preferred embodiment of the present invention, the first and second liquid passing holes are regular or irregular liquid passing holes.
In a preferred embodiment of the invention, the liquid passing area is a single liquid passing hole, and the puncturing part is inserted into the penicillin bottle so that part of the single liquid passing hole is positioned outside the penicillin bottle, and the rest part of the single liquid passing hole is positioned inside the penicillin bottle.
The invention has the beneficial effects that: the dispensing needle for the penicillin bottle can ensure that the air pressure in the penicillin bottle is balanced with the air pressure outside the penicillin bottle, and can avoid the phenomenon that a rubber plug is washed open and too much liquid medicine remains in the bottle due to liquid accumulation in the bottle caused by multiple times of suction.
