Abstract
A cannula is retractably mounted with a needle holder ( ) in a housing ( ). A switching device ( ) allows the hollow needle ( ) to be retracted after use into the housing ( ). The needle holder ( ) secures against rotation the hollow needle ( ) in the housing ( ) in a predetermined orientation. The housing ( ) is preferably provided on its outer side with markings ( ) which indicate the orientation of the hollow needle ( ). The hollow needle ( ) cannot twist when it is retracted. Another advantage is that the orientation of the needle point need not be determined before making an injection.
