Abstract

The article of this design is a syringe equipped with a filter that can filter out solid matter in a drug, and can suppress the drug's injection resistance while capturing, for example, protein aggregates in the drug when administering the drug. In addition, by providing an inner stopper in the housing that moves when administering the drug, the drug filled in the cylinder does not come into contact with the filter during storage.
