  • Patent number: 11964088
    Abstract: 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.

  • Patent number: 11738129
    Abstract: A method for operating a dialysis machine to conduct a dialysis treatment on a patient (e.g., a peritoneal dialysis machine) may include transferring dialysate from a first bag, and automatically determining the dialysate from the first bag has completely transferred. After determining the dialysate has completely transferred from the first bag, switching from the first bag to a second bag of dialysate. The method may further include transferring dialysate from the second bag in response to the detection of the completed transfer of the first bag, and automatically determining the dialysate from the second bag has completely transferred. The method may further include determining if the respective first or second bag has completely transferred by comparing a dialysate bag volume transferred to the patient to a detected volume of the respective first or second bag. Systems with dialysis machines for performing such a method are disclosed as well.

  • Publication number: 20230019082
    Abstract: A dialysis system includes include a home dialysis machine and a home gateway device in communication with a cloud-based application via a connected health system. The gateway device has voice recognition capabilities. A user can provide spoken information to the gateway device, and the gateway device can cause one or more actions to be performed. The gateway device may cause a dialysis function to be performed by the dialysis machine, or data to be input into the dialysis machine. The gateway device can also communicate with one or more other systems (e.g., remote systems) via the cloud-based application. In some examples, the cloud-based application can communicate with an order management system to allow the user to order medical supplies (e.g., for use with the dialysis machine) via the gateway device. The gateway device can provide two-way conversational capability (e.g., back and forth communication) between the user and the gateway device.

  • Patent number: 11344657
    Abstract: Dialysis machines and methods for operating dialysis machines (e.g., peritoneal dialysis machines) may include delivering dialysate to a patient and detecting a temperature of a volume of the dialysate, an air content of the dialysate volume, or another condition, or combinations thereof, wherein the detected temperature of the dialysate volume is compared to a predetermined maximum temperature, the detected air content of the dialysate volume is compared to a predetermined maximum air content and the detected other condition generates a signal. The volume of dialysate may be diverted in response to the detected temperature exceeding the predetermined maximum temperature, the air content exceeding the predetermined maximum air content, or the other condition generated signal, or combinations thereof.

  • Patent number: 11342073
    Abstract: Medical devices may have the ability to connect through a secure gateway to a network, including both local and external networks. According to the described system, a connection component of the medical device may include a wireless connection dongle system using a wireless adapter, such as a dongle, that is inserted into and/or otherwise coupled to the medical device and that transmits or casts information wirelessly, such as via real-time streaming, to a separate receiving display. The communication may be facilitated by another dongle inserted into and/or otherwise coupled to the receiving display that receives the casted display screen. This transmitted casting capability provides the ability to connect the medical device, such as a peritoneal dialysis machine, to other display devices to duplicate the screen of the medical device on one or more larger or more easily accessible displays via secure one-way communication.
