Method and apparatus for overload protection in medicament syringe pumps

摘要

An overload protection method and apparatus for a medicament syringe pump force sensor. A dome switch is employed with force sensor components of a medicament pump. The dome switch collapses at overload pressures, isolating the force sensor from pump driving forces that exceed the force sensor limit. An alarm signal can be triggered by the overload, and initiate pump shut down.
