ABSTRACT:
A needle holder includes a base body which receives the puncturable closure of a medical preparation holder. A hub part, containing the needle, is mounted in the base body through a first threaded connection for movement to a work position in which the needle punctures the closure. A protective sleeve for the needle is mounted on the base body through a second threaded connection, oppositely threaded with respect to the first connection. The sleeve and the hub part are coupled by an axial gear tooth arrangement which permits axial movement of the hub part upon rotation of the protective sleeve on the base body.
The base body may exhibit a variety of forms, the second threaded connection may include a saw tooth profile which permits the protective sleeve to be slid on a base body without rotation, and a friction coupling may be provided between the hub part and the protective sleeve.
