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.

Non-touch communication with a dialysis machine using a connected health system

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.

Volume-based priming of dialysis machines

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.

Automatic dialysate detection in dialysis machines

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.

Dialysis solution waste minimization systems and methods

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.

Transmitted display casting for medical devices

A dialysis machine (e.g., a peritoneal dialysis machine) may include a housing. The machine may further include a leak detector disposed in the housing, the leak detector being an electrical circuit. In response to fluid contacting the leak detector, a leak in the dialysis machine is detectable. The machine is configured to send a signal based on a short of the electrical circuit from fluid contact with the leak detector to indicate a leak condition.

Fluid leak detection in a dialysis machine

A sensor assembly measures characteristics of a fluid entering or exiting a patient via a catheter. The sensor assembly includes a flow tube that accepts the fluid at a first end thereof expels the fluid at a second end thereof, a plurality of sensors disposed about the flow tube, the sensors including at least one temperature sensor that measures temperature of the fluid and at least one pressure sensor that measures pressure of the fluid, and a connector that connects the sensor assembly to the catheter. The sensors may also include a clarity sensor, a conductivity sensor, a flow sensor, and/or an air detector. The sensor assembly may also include a wireless communication device that provides wireless communication. The sensor assembly may communicate with a dialysis machine via a network. The dialysis machine may be a peritoneal dialysis machine.

Smart connector for a medical device

An intelligent support assembly, for example, a mobile support assembly (e.g., cart) for a dialysis machine (e.g., a peritoneal dialysis cycler), and methods for performing dialysis treatment using such an assembly. The intelligent support assembly may be configured to determine one or more properties relating to a dialysis treatment being performed on a patient using the dialysis machine, and to control one or more actions that affect the dialysis treatment based at least in part on the determined one or more properties. The cart may be configured to receive information corresponding to the one or more properties from, and transmit such information to, the dialysis machine, network access devices, sensor devices, and other devices. The controlled actions may include adjusting a height of dialysis solution or other items relative to a height of the patient, and moving the cart relative to the location of the patient.

Smart cart for a dialysis machine

Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments, may include a dialysis machine for transferring dialysate to a patient from a dialysate bag, and a warmer pouch for flowing the dialysate through to heat to a predetermined temperature before flowing into the patient. The dialysate may flow from the dialysate bag through the warmer pouch for pumping into the patient via tubing. A filter may be coupled to the warmer pouch, and the filter may be configured to filter out air content from the dialysate.
