CASSETTE ASSEMBLY FOR SYRINGE FILL SYSTEM

摘要

A syringe fill system is described, which is useful for filling syringes for dental anesthetic applications. The system incorporates capability for “push-pull”, “pull-push”, “push-push”, and “pull-pull” modes of operation, for loading syringes with compositions comprising multiple fluid components. A syringe fillable by such syringe fill systems is described, providing haptic and audible feedback to a user, to aid in administering precise amounts of therapeutic compositions. Also disclosed are cassette assemblies for use in such syringe fill systems. Such cassette assemblies may be formed of plastic and elastomeric materials of construction, as disposable or single-use components of the syringe fill system.

1. A cassette assembly, comprising:
a base manifold member including an interior manifold flow passage; multiple fluid feed inlets extending outwardly from the base manifold member and communicating with the interior manifold flow passage via inlet passages containing check valves, the multiple inlets being configured for engagement with respective fluid supply packages; and a syringe coupling mounted on the base manifold member, in fluid flow communication with the interior manifold flow passage to deliver fluid from the interior manifold flow passage to a syringe when coupled to the syringe coupling.
