Summary
Peritoneal Perfusion Control System With Automated Pumps, Sensors
What changed
USPTO published patent application US20260097159A1 for a peritoneal perfusion control system utilizing automated inflow and outflow pumps, weight sensors, and flow-rate sensors. The system employs model-based multivariable control with drainage efficiency estimation for safety compliance.
Medical device manufacturers developing peritoneal dialysis or perfusion systems should review this application to assess prior art implications and identify potential licensing opportunities for automated perfusion control technology.
What to do next
- Monitor for updates on patent prosecution status
- Review for prior art considerations

SYSTEMS AND METHODS OF SAFE MODEL-BASED MULTIVARIABLE CONTROL OF PERITONEAL PERFUSION

Abstract
In accordance with the present disclosure, a method for automatically controlled peritoneal perfusion includes receiving perfusion parameters such as a predefined intra-abdominal volume and inflow rate and circulating a perfusate between a reservoir and a subject's cavity using an inflow pump and an outflow pump. A reservoir volume may be measured by a weight sensor, inflow data may be obtained from a flow-rate sensor and a commanded flow rate may be accessed from the outflow pump. A drainage efficiency of the outflow pump may then be estimated using the reservoir volume, inflow rate, and the commanded outflow rate. A drainage efficiency model may be identified from experimental or operational data to represent efficiency dynamics. Based on this model, a perfusion safety control routine may evaluate a safety barrier function and adjust operation of the inflow and outflow pumps to maintain safety and compliance with the perfusion parameters.
