Further, the first connecting part is the first sleeve part, the second connecting part is the second sleeve part, and there is a gap between the first sleeve part and the second sleeve part for fixing the puncture needle and pulling the first sleeve The middle partition wall separating the internal space of the first sleeve part and the second sleeve part.

Further, the second sleeve part is a stepped sleeve, including a threaded upper sleeve section on the upper part and a lower sleeve section on the lower part, the inner diameter of the lower sleeve section is larger than the thread diameter of the upper sleeve section .

Further, the inner surface of the first sleeve part has a plurality of block-shaped stop protrusions distributed along the circumference.

Further, the end of the puncture needle does not protrude from the end of the sleeve.

According to the technical scheme of the utility model, the infusion package and the dispensing bottle are connected through the drug mixing joint composed of the sleeve part and the puncture needle, so that the dispensing process is simple, convenient and safe, and the drug liquid is prevented from being polluted. The connecting part of the combination cap of the infusion package is connected, and the empty penicillin bottle and the mixed drug joint after the medicine is dispensed are connected with the large infusion package, so that during the infusion, you can clearly know what medicine is in the large infusion, so as to avoid the possibility of using the wrong medicine Situation happens.
