Abstract
Official abstract text for this publication.
A coupling system for receiving a push rod includes a housing defining an internal channel having a sloped wall, and a piston received within the internal channel. The piston includes at least one flexible member arranged within the channel to be acted upon by the sloped wall to engage the push rod. The only external force required to couple the push rod is an axial force on the piston in a direction. The only external force required to de-couple the push rod is an axial force on the piston in an opposite direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A pump system, comprising: a pump console housing a push rod, a motor and a transmission for driving the push rod in an axially reciprocal motion, the console including a pump interface; a disposable pump configured to removably mate with the pump interface by advancing the disposable pump in an axial direction corresponding to the axis of reciprocal motion of the push rod such that the push rod extends into an internal channel of the disposable pump, the…
