Weight-based peritoneal dialysis system including a drain trolley
Summary
The USPTO granted Patent US12594369B2 to Baxter International Inc. for a peritoneal dialysis system featuring a weigh scale supporting fluid supply containers and a drain trolley. The system includes a control unit managing fill, dwell, and drain cycles through pump and valve operation, with 19 claims covering the integrated dialysis apparatus design.
What changed
The USPTO granted Patent US12594369B2 to Baxter International Inc. covering a peritoneal dialysis system with a weigh scale, multiple fluid supply containers arranged vertically, and a drain trolley sized to contain all patient effluent. The system uses a control unit to manage fill, dwell, and drain cycles via pump and valve operation, with dialysis fluid pumped from the bottom container and effluent drained by gravity to the trolley.
Medical device manufacturers developing peritoneal dialysis equipment should assess whether their products fall within the scope of these 19 claims. Competitors in the home dialysis market may face restricted design options or need to pursue licensing arrangements with Baxter to avoid infringement exposure.
What to do next
- Review patent claims for potential infringement
- Assess freedom to operate in peritoneal dialysis system development
- Consider licensing options if developing similar weight-based dialysis technology

Abstract
A dialysis system and dialysis machine or cycler are provided that decrease a disposable set's cost and complexity. The dialysis machine or cycler includes a weigh scale on which multiple fluid supply containers containing dialysis fluid, and a drain trolley, are positioned. The fluid supply containers may be elevated relative to the drain trolley. The drain trolley is sized to contain all of the effluent drained from a patient during a dialysis treatment. The fluid supply containers are in fluid communication with one another and arranged one of top of the other. A control unit may control fill, dwell and drain cycles by controlling the operation of a pump and a valve. Dialysis fluid from the bottom-most fluid supply container may be pumped into a patient. The valve may be opened to allow effluent to drain from the patient to the drain trolley by way of gravity.
