Abstract

A syringe apparatus is provided for stirring and delivering single or multi-component compositions. The syringe apparatus comprises a syringe barrel, a plunger, a stirring paddle, and a connecting member. The plunger partially disposed within the syringe barrel is movable along an axial direction of the syringe barrel. The stirring paddle disposed within the syringe barrel has one end passing through the plunger and slidably disposed within the plunger. The syringe apparatus of the disclosure can stir the components and deliver the mixture safely for maintaining a good hygiene condition during the therapeutic process.
