摘要：
a dispensing method of powder for injection and a dispending device thereof, comprising: establishing an enclosed replacing channel between a medicine bottle(b) and a liquid bottle(B) generating pumping force in the replacing channel by a external-force-driving device pumping liquid from the liquid bottle(B) into the medicine bottle(b) for dissolving medicinal powder and refilling a medicinal powder dissolved solution back into the liquid bottle(B) pumping air into the medicine bottle(b), and discharging the medicinal powder dissolved solution remained in the medicine bottle(b) and the replacing channel into the liquid bottle(B) to a maximum extent, so as to finish the dispensing process of completely transferring the medicinal powder from the medicine bottle(b) to the liquid bottle(B). The dispensing device comprises a driving device(11) and a dispenser, the dispenser is composed of a displacement rod(1) and an elastic flexible pipe(2), alternatively, the dispenser can be a double-channel or single-channel replacing needle, which completes the dispensing process via gas-liquid replacement between the two sterile spaces, i.e. the medicine bottle(b) and the liquid bottle(B), without communicating with the environment air, so it can avoid the air contamination effectively during the dispensing process, meanwhile the powder for injection in the medicine bottle(b) can be completely dissolved and displaced so as to reduce the medicine wasting, simplify the dispensing process, and improve the dispensing efficiency.La présente invention concerne un procédé de distribution de poudre pour injection et un dispositif de distribution pour celui-ci, comprenant : létablissement dun canal de remplacement confiné entre un flacon de médicament (b) et un flacon de liquide (B) la génération dune force de pompage dans le canal de remplacement par un dispositif dentraînement par force externe le pompage de liquide depuis le flacon de liquide (B) dans le flacon de médicament (b) pour d
