The invention discloses an infusion bag extruding mechanism used for
penicillin bottle medicine dispensing and a
medicine dispensing method. The extruding mechanism comprises a base plate, wherein the base plate is provided with mounting stations of an infusion bag and a
penicillin bottle, a bracket is arranged above the mounting
station of infusion bag, the bracket is provided with a
cam and at least one universal-
ball bearing on the
cam, the
cam is connected with a swing component and is driven by the swing component to perform reciprocating swing, the
turning radius of the at least one universal-
ball bearing on the cam is greater than the distance from the bracket to the surface of the infusion bag. The
medicine dispensing method comprises the following steps: making preparation, extruding the infusion bag, rotating the base plate, and extruding the infusion bag again, thus completing the medicine dispensing process. The extruding mechanism is simple in structure and convenient to use, the liquid medicine can be directly injected into or flow out of the infusion bag and the
penicillin bottle without a transfer container for communicating the infusion bag and the penicillin bottle, therefore, the structure is optimized, and the
cross infection is avoided; compared with the manner of manually extruding the infusion bag, the medicine dispensing method provided by the invention has the advantages that the automatic extruding or releasing for the infusion bag can be realized, therefore, the medicine dispensing efficiency is improved, and the medicine dispensing time is saved.
