The needle of the syringe is exposed to the outside for many times, and it is easy to inject unfiltered air. The particles in the air enter the drug solution, causing drug solution contamination. Therefore, a drug dispensing filter appears. The prior art Chinese patent publication number CN209735478U discloses a single-membrane drug dispensing filter device, which includes: a filter body, wherein the filter body also includes a first split plate and a second split plate, the first split plate and the second split plate are plugged into each other and form a main body cavity, the first split plate has a cavity inlet, the second split plate has a cavity outlet, and the cavity inlet and the cavity outlet are connected to the main body cavity; a filter membrane, the filter membrane is arranged in the filter body; and two puncture components, the puncture components are respectively arranged on both sides of the filter body, each of the puncture components has a drug channel, the drug channel has an inlet end and an outlet end, wherein the two outlet ends are respectively connected to the cavity inlet and the cavity outlet. The disadvantage is that when the medicine in the powder injection bottle is introduced into the infusion bottle, the medicine bottle is sealed and airtight, and the medicine liquid circulates slowly, which makes the dispensing efficiency low, especially when the infusion bottle is a hard bottle that cannot be squeezed, so the dispensing of the medicine bottle cannot be realized. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned disadvantages and provide a drug dispensing filter with fast drug liquid circulation speed, high drug dispensing efficiency, convenient processing and low cost, especially capable of dispensing drugs when the drug bottle is a hard bottle that cannot be squeezed.

[0004] The purpose of the present invention and the solution of its main technical problems are achieved by adopting the following technical solutions:

[0005] A drug dispensing filter of the present invention is characterized in that a retaining ring A and a retaining ring B are respectively provided at the left and right ends of the main body, an integrated puncture portion A is provided on one end of the retaining ring A, an air port A and a medicine hole C are respectively provided on the main body, the retaining ring A and the puncture portion A, an integrated puncture portion B is provided on one end of the retaining ring B, a medicine hole A and a medicine hole B are respectively provided on the main body, the retaining ring B and the puncture portion B, the medicine hole A, the medicine hole B and the medicine hole C are connected and separated by a medicine liquid filter membrane, an integrated liquid blocking funnel is provided in the air port B, an air filter membrane is placed in the air port B and is inserted into one end of the cover for fixing.

[0006] The gas port A, the gas port B and the liquid blocking funnel are connected.

[0007] The air port A is isolated from the medicine hole A, the medicine hole B and the medicine hole C.

[0008] The air port A and the medicine hole A are straight holes arranged in a mirror image, and the medicine hole C and the medicine hole B are straight holes arranged in a mirror image.

[0009] An integrated baffle is arranged at the lower end of the main body.

[0010] Compared with the prior art, the present invention has obvious beneficial effects; it can be seen from the above technical scheme that: by respectively arranging integral retaining rings A and retaining rings B at the left and right ends of the main body, an integral puncture portion A is arranged on one end of the retaining ring A, an air port A and a medicine hole C are respectively arranged on the main body, the retaining ring A and the puncture portion A, an integral puncture portion B is arranged on one end of the retaining ring B, a medicine hole A and a medicine hole B are respectively arranged on the main body, the retaining ring B and the puncture portion B, the medicine hole A, the medicine hole B and the medicine hole C are connected and separated by a medicine liquid filter membrane, an integral air port B is arranged on the main body, an integral liquid blocking funnel is arranged in the air port B, an air filter membrane is placed in the air port B and inserted into one end of the cover to be fixed. When the puncture part A and the puncture part B are respectively inserted into the medicine bottle, the puncture part A is in the upper medicine bottle, and the air is filtered from the hollow cover through the air filter membrane into the upper end of the air port B, and then passes through the small hole on the liquid blocking funnel to enter the lower end of the air port B and enter the upper medicine bottle from the air port A. After the filtered air enters the medicine bottle, the medicine liquid in the upper medicine bottle quickly flows into one end of the main body through the medicine hole A and the medicine hole B, passes through the medicine liquid filter membrane to filter impurities, and then flows into the other end, and finally flows into the medicine bottle from the medicine hole C. When the main body is upright, the medicine liquid is blocked by the liquid blocking funnel when entering the lower end of the air port B, and cannot penetrate into the upper end of the air port B. The medicine liquid will not seep out from the air port B and the cover, thereby achieving a fast circulation speed of the medicine liquid and a high dispensing efficiency. Among them, the main body, the retaining ring A, the puncture part A, the retaining ring B, and the puncture part B are formed at one time, and the processing is convenient and the cost is low. In short, the medicine liquid of the present invention has a fast circulation speed, a high dispensing efficiency, is convenient to process, and the cost is low, especially it can realize the dispensing of the medicine bottle that is a hard bottle and cannot be squeezed.
