<p>A device for preventing air contamination when transferring a substance from a vessel (24) to a second vessel (10; 15) and further to the desired application, for example injection into a patient or other application. The device is attached or connectible to said vessel (24) and comprises a first member (10), in which a puncturing member (16), e.g. a needle provided with a passage is enclosed. The first member (10) has a sealing member (18), e.g. a membrane through which the needle can be passed. The device further comprises a second member (20), which is detachably connectable to the first member (20) and which also has a sealing member (19), e.g. a membrane. When the first and second members (10, 20) are connected to each other the two sealing members (18, 19) are located in a position with respect to each other so that they can be penetrated by the puncturing member (16), which is movable with respect to the sealing members (18, 19).</p> |
