Abstract
Methods for the sterile transfer of a solution are disclosed, including sterilizing the inlet to a connector by flowing a sterilizing fluid around the connector inlet, sterilizing a penetrating element for the connector by flowing a sterilizing solution around the penetrating element, and penetrating the sterilized inlet by the sterilized penetrating element in order to transfer the solution through the penetrating element on the connector. Apparatus for such sterile transfer of a solution is also provided.
Claims8
Apparatus for the sterile transfer of a solution from a first location to a second location, said apparatus comprising a housing having an inlet in fluid communication with said first location, a sterilizable connector having an inlet for insertion into and removal from said housing, recirculation means for recirculating a sterilizing solution into said housing through said housing inlet for sterilizing said housing inlet of said sterilizable connector inlet when said sterilizable connector is inserted into said housing and in order to supply said solution to said second location through said sterilizable connector, and heating means for heating said sterilizable solution to a temperature of greater than about 120° C.
Apparatus for the sterile transfer of a solution comprising a housing having an inlet and containing a penetrating member, a sterilizable connector having an inlet for insertion into said housing to a predetermined position adjacent to said penetrating member and an outlet, said inlet including a penetrable seal for sealing said sterilizable connector from the atmosphere, circulation means for circulating a sterilizing solution into said housing to said predetermined position whereby said sterilizing solution can sterilize said penetrating member and said inlet of said sterilizable connector, and means for causing said penetrating member to penetrate said penetrable seal, whereby said sterilizing solution can flow through said sterilizable connector.
