摘要：
Methods of maintaining or providing sterile or specific pathogen free environments are disclosed. The methods involve the use of semi-permeable membrane materials between the sterile or pathogen free environment and surrounding potentially hostile environments. One particular method and apparatus is described for introducing drugs or other secondary substances to a sterile liquid for example for transfusion to a patient. The apparatus has a first port (4) for connection to a container of sterile solution second port (5) for connection to a transfer tuber and a third port (9) for introduction of the secondary substance. The connection between the third port and the other ports is by way of a semipermeable membrane (11) selected to permit the passage of the secondary substance while preventing the ingress of pathogens or other potentially harmful organisms.
