ABSTRACT:
A first aspect of the invention relates to a method for aseptic preparation with an injection syringe. The syringe comprises a container for injection agent and an immovable connection nozzle connected to the container. The method entails charging the container with air. According to the invention air is forced to pass through an air filter arranged on the connection nozzle. This enables the syringe container to be charged with aseptic air in a simple and reliable fashion. Other aspects of the invention relate to devices for performing the method, viz. an injection syringe equipped with an air filter in the connection nozzle, a filter unit (2) connectable to an injection syringe's (1) connection nozzle (13) and a system comprising an injection syringe (1) and a separate filter unit (2). The invention devices convey advantages of the same kind as the invention method.
