摘要： 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.
