摘要： Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a dialysis machine for transferring dialysate to a patient from a dialysate source. The dialysate may flow from the dialysate source through a cartridge or cassette (e.g., a disposable cartridge or cassette) positionable within the dialysis machine. The dialysis machine includes a piston or pump for pumping fluid (e.g., dialysate) from the cassette to the patient. In various embodiments, the dialysis machine includes one or more sensors for monitoring a condition. For example, the dialysis machine may include sensor(s) for monitoring proper alignment of the cassette within the cassette compartment, or sensors mounted on the pump head for monitoring a leak during a dialysis operation, or sensors for monitoring improper operation of the pumps (e.g., pistons), or a combination thereof.

摘要： A medical treatment machine, such as a dialysis machine (e.g., a home dialysis machine, such as a home hemodialysis machine or a home peritoneal dialysis machine) can receive a digital prescription file that defines parameters of a medical treatment to be administered to a patient. The digital prescription file can be prepared and delivered in such a way that the medical treatment machine can confirm that the issuer (e.g., provider) of the digital prescription file is an authorized issuer without having any a priori knowledge of the particular issuer. The digital prescription file can be delivered irrespective of the inherent security (or lack thereof) of the transmission medium in a tamper-evident format using minimal resources necessary to verify the validity of the digital prescription file and its issuer. The digital prescription file may be delivered to the dialysis machine using a network cloud-based connected health system.

摘要： An extracorporeal blood treatment device and a method are provided for removing a secondary membrane formed on a semipermeable membrane of a dialyzer during an extracorporeal blood treatment. The extracorporeal blood treatment device operates in a first operating mode in which a dialysate outlet valve is open such that dialysate flows through a dialyzer feed line, through a dialysate chamber, and into and through a dialyzer discharge line. The extracorporeal blood treatment device operates in a second operating mode to remove the secondary membrane from the semipermeable membrane. During the second operating mode, the dialysate outlet valve is closed for a duration of time such that dialysate is prevented from flowing through the dialyzer discharge line. A backflush procedure results wherein a volume of dialysate passes from the dialysate chamber through the semipermeable membrane and into the blood chamber.

摘要： A hemodiafiltration (HDF) system is provided for performing HDF treatment. The HDF system includes a mixing system for mixing nitric oxide (NO) with other chemicals to produce a dialysis fluid. The HDF system further includes an extracorporeal blood circuit that includes a filter for separating the dialysis fluid into a dialysate and NO spiked substitution fluid. The extracorporeal blood circuit also includes a dialyzer that receives the dialysate and a blood line connected to the dialyzer. The blood line includes admission points connected to the filter. The admission points are used to administer the NO spiked substitution fluid to the patient during the HDF treatment.

摘要： 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. The metadata signature can be derived by running an error-check/error-correct algorithm (e.g., SHA256) on the computer code of the electronic component. A use of the metadata signature enables detection of any unauthorized changes to the computer code as compared to the pre-authenticated code.

摘要： A dialysis system may include a dialysis machine (e.g., a peritoneal dialysis machine) having a fluid system for delivering fluid (e.g., dialysate) to a patient. The dialysis machine may include at least one processor and a memory coupled to the at least one processor, the memory comprising instructions that, when executed by the processor, may cause the at least one processor to determine volume information for a fluid system of a dialysis machine, wherein the volume information may comprise a patient line volume and an accuracy adjustment volume, and to determine a priming volume to prime the fluid system with a fluid based on the volume information. Other embodiments are described.
