Infusion Pump Mechanism with Occlusion Force Reduction
Summary
The USPTO published patent application US20260097166A1 for an infusion pump mechanism featuring multi-directional tolerance control to reduce occlusion force. The invention includes pump fingers with head portions having tips configured to contact and occlude tubes, and an opposing plate with force concentrators aligned with respective pump fingers. The application was filed on December 12, 2025, under application number 19418139.
What changed
The USPTO published a patent application for an infusion pump mechanism that reduces occlusion force through multi-directional tolerance control. The mechanism includes multiple pump fingers with body and head portions, where head portion tips contact and occlude tubes, and an opposing plate with force concentrators corresponding to each pump finger. Force concentrators include concentration surfaces that contact the tube opposite to the finger tip, distributing pressure during occlusion.
For medical device manufacturers and healthcare technology companies, this patent represents potential prior art in infusion pump design. Companies developing similar occlusion mechanisms should review the claims to assess potential licensing needs or design-around considerations.
What to do next
- Monitor for patent grant status
- Review claims for potential infringement concerns

Abstract
An infusion pumping mechanism includes a motor, a plurality of pump fingers and an opposing plate. Each finger of the pump fingers includes a body portion and a head portion. The head portion includes a tip that is configured to contact and occlude a tube installed in the pumping mechanism. The opposing plate includes an anvil with a plurality of force concentrators. A force concentrator of the plurality of force concentrators corresponds to a respective pump finger of the plurality of pump fingers. Additionally, the force concentrator includes a concentration surface configured to contact and occlude the tube. The force concentrator is aligned with a tip of the respective pump finger such that as the finger is directed towards the tube and contacts the tube, both the tip and the force concentrator provide pressure to opposite sides of the tube and at least partially occlude the tube.
