ABSTRACT:
A transfusion device comprising a flexible vessel containing a solvent fluid, a drug container containing a drug, and a communicating portion for communicating the vessel and the container with each other, the commuicating portion comprising first and second passages adapted to communicate with the vessel and container and held in engagement with each other, a membrane and a plug member which are provided for closing the two communicating passages, and a particular cap held in thread engagement with the second communicating passage for enabling the two passages to communicate with each other.
When the vessel and the container are rotated relative to each other, the cap slides to disengage the plug member of the second communicating passage and break the membrane of the first communicating passage, thereby allowing the vessel and the container to communicate with each other.
