Utility
Authentication of medical device computing systems by using metadata signature
15 Aug 23
Computer code embedded in an electronic component (e.g., a processor, a sensor, etc.) of a medical device, such as a dialysis machine, can be authenticated by comparing a metadata signature derived from the computer code of the electronic component to a key derived from a pre-authenticated code associated with the electronic component.

Utility
Preserving sorbent devices in dialysis systems
4 Jul 23
A method of preserving a sorbent device of a dialysis system, the method comprising—after administering a first dialysis treatment at the dialysis system and before administering a second dialysis treatment at the dialysis system—circulating a fluid through the sorbent device to prevent matter within the sorbent device from solidifying and circulating the fluid through a filter coupled to an outlet of the sorbent device to remove contaminants from the fluid.

Utility
Determining a Volume of a Container for Dialysis Treatment
29 Jun 23
A method includes receiving, by a processor of a dialysis machine, a dialysate flow rate, a bicarbonate setting value, a signal from a pressure sensor configured to measure a pressure within a container, and a signal indicating a state of a fill valve; determining, based on the signal received from the pressure sensor and the state of the fill valve, fill parameters; determining a volume of the container based on at least two of the fill parameters; determining a depletion time in which the concentrate will be depleted from the container based on the volume of the container, the dialysate flow rate, and the bicarbonate setting value; determining, based on the depletion time, an amount of time remaining before the concentrate will be depleted from the container; and causing the dialysis machine to indicate the amount of time remaining before the concentrate will be depleted from the container.

Utility
Peritoneal Dialysis System with Constant Volume Disposable Pump
29 Jun 23
In one aspect, a peritoneal dialysis (PD) system includes a housing that receives a disposable cassette, a plurality of pinch valves that receive respective sections of fluid tubing of the disposable cassette, an air port that forms an airtight seal with an air line of the disposable cassette, an air pump that alternatingly pushes air out of the air port and pulls air in from the air port, and a computer processor that controls the plurality of pinch valves and the air pump such that the cassette performs a dwell phase in which the diaphragm pump pumps fresh dialysate from a dialysate bag to a heater bag, a fill phase in which the diaphragm pump pumps the fresh dialysate from the heater bag to a patient line, and a drain phase in which the diaphragm pump pumps spent dialysate form the patient to a drain.
