Abstract
An improved medication dispensing device includes an apyrexia receptacle, a transport pipeline, a perfusion device, a filter, and a dispensing needle, which operates in an environment in compliance with Class 100 laminar air ventilation. The perfusion device erected at the middle of the transport pipeline which has two ends linking to the apyrexia receptacle and the filter, respectively. In operation, the perfusion device pumps the prepared medication solution from the apyrexia receptacle to get through the filter to remove particles and bacterium, and a thin tubular dispensing needle which punctures the rubber plug of an aseptic bottle. An axial groove rendered in middle section of the dispensing needle forms a pressurized seal part with the rubber plug resiliently wrapped around at the middle of the dispensing needle to discharge redundant air pressure accumulating in the aseptic bottle while keeps outside air from entering.
