Process for mixing and dispensing a flowable substance

Abstract

A process and apparatus for use in mixing and applying a flowable substance that consists of a powdered first component and a liquid second component. The mixing of the two components form a flowable substance, especially a bone cement. The apparatus uses an injection syringe. The first component is placed into the injection syringe after removing the syringe plunger and placing a closing device or cap onto the dispensing end of the syringe. The liquid component is added to the syringe, preferably from a second syringe filled with the liquid component via a hollow needle of the second syringe. The first syringe is closed at the filling with the syringe plunger under the load of sufficient air in the syringe cylinder. The components are mixed by shaking the first syringe. The lid of the first syringe is removed and a hollow needle is placed onto the first syringe and the flowable substance is delivered at a desired site.
