Publication number: 20250205404Abstract: This disclosure teaches methods and systems for determining membrane transport parameters of a peritoneal dialysis (PD) patient, and updating a (PD) prescription of the patient based on one or more of the membrane transport parameters. The methods include withdrawing a plurality of samples of PD effluent from the patient's peritoneal cavity periodically during one or more dwell phases of one or more PD treatment cycles. The method further includes obtaining sensor measurements of the samples of PD effluent, determining one or more peritoneal membrane transport parameters based on the sensor measurements, and updating the patient's PD prescription, to be used for a later peritoneal dialysis treatment, based on the one or more peritoneal membrane transport parameters.Type: ApplicationFiled: December 18, 2024Publication date: June 26, 2025Inventors: Paul Chamney, David Yuds, Eric Bergman, Kerissa Adams, Jun Yi

Publication number: 20250204812Abstract: This disclosure provides methods and systems for peritoneal dialysis (PD) effluent sampling and measurement, which are compatible with all types of PD treatment, and would enable more frequent assessment so a patient's PD prescription can be updated routinely. The methods include withdrawing a plurality of samples of PD effluent from the patient's peritoneal cavity periodically during the dwell phase of a PD treatment cycle. The method further includes obtaining sensor measurements of the samples of PD effluent. The method may return each PD effluent sample to the patient's peritoneal cavity after the measurement. Alternatively, the PD effluent samples may be stored in a container without returning them to the patient's peritoneal cavity.Type: ApplicationFiled: December 18, 2024Publication date: June 26, 2025Inventors: David Yuds, Paul Chamney, Eric Bergman, Kerissa Adams, Jun Yi

Patent number: 12296077Abstract: A medical treatment machine, such as a home dialysis machine, can receive prescription parameters that define parameters of a medical treatment to be administered to a patient. A medical prescription is entered by a clinician into a clinical information system (CIS) that calls a system to evaluate the compatibility of the entered prescription by transmitting the prescription parameters to a server that has access to a database of medical devices and their operational parameters. The server compares the treatment parameters of the medical prescription to the operational parameters of the medical device and generates a prescription compatibility response indicting if the treatment parameters of the medical prescription can be executed by the medical device. The server returns to the CIS the prescription compatibility response to allow the prescription, e.g. in a digital or program form, to be securely transmitted or delivered via a connected health system to the medical device.Type: GrantFiled: January 16, 2024Date of Patent: May 13, 2025Assignees: Fresenius Medical Care Holdings, Inc., Fresenius Medical Care Deutschland GmbHInventors: Paul Chamney, Harvey Cohen
