Method for the production of pharmaceutical products
View Patent ↗A method for the preparation of pharmaceutical products according to which a diluent is fed into a container containing a lyophilized or powdered pharmaceutical through a needle, which is then extracted from the container, inserted in its protective cap, and rinsed by feeding the diluent through the needle and into the protective cap itself.
1. A method for the preparation of pharmaceutical products comprising the steps of:
feeding a container ( 7 ) containing a lyophilized or powdered pharmaceutical into a dilution station ( 75 );
inserting a needle ( 78 ) into the container ( 7 );
feeding a diluent into the container ( 7 ) by means of the needle ( 78 ); and
extracting the needle ( 78 ) from the container ( 7 );
and characterized in that it further comprises the steps of:
inserting the needle ( 78 ) into a protective cap thereof ( 85 ); and
feeding the diluent through the needle ( 78 ) and into its protective cap ( 85 ) to rinse the needle ( 78 ) itself.
2. A method according to claim 1 comprising the following step:
inserting the protective cap ( 85 ) in a collection reservoir ( 82 ) of the diluent fed through the needle ( 78 ).
3. A method according to claim 2 comprising the step of:
discharging the diluent from the collection reservoir ( 82 ) into a collection manifold ( 83 ).
4. A method according to claim 3 comprising the steps of
lowering the collection reservoir ( 83 ) to disengage the needle ( 78 ) from the protective cap ( 85 ); and
lifting the collection reservoir ( 83 ) to engage the needle ( 78 ) in the protective cap ( 85 ).
5. A method according to claim 1 , comprising the steps of:
aspirating the diluent from a containment reservoir ( 77 ) by means of a syringe ( 80 ); and
feeding the diluent to the needle ( 78 ) by means of the syringe ( 80 ) itself.
6. Method according to claim 1 , comprising the following step:
rinsing the needle ( 70 ) with an amount of diluent sufficient to rinse the protective cap ( 85 ) as well.
