This disclosure teaches a system and method for monitoring an extracorporeal blood circuit of a patient and identifying a needle dislodgement. The method includes identifying a potential needle dislodgement event based on changes in pressure of the extracorporeal blood circuit, searching for a heart rate of a patient by analyzing an optical backscatter signal from an optical sensor attached to the extracorporeal blood circuit or by analyzing a pressure signal representative of the pressure in the extracorporeal blood circuit, and verifying the potential needle dislodgement event is a needle dislodgement based on the absence of the heart rate.

Needle dislodgement detection systems and methods

This disclosure relates to remote control of dialysis machines. In certain aspects, a method includes receiving a request for a network connection from a dialysis machine and establishing the network connection with the dialysis machine. The method also includes receiving, from a client device, a request to access the dialysis machine, authorizing the client device to access the dialysis machine, receiving, from the dialysis machine, information pertaining to an operation of the dialysis machine, and providing, to the client device, the received information.

Communication with home dialysis machines using a network connected system

A method including automatically performing at least one integrity test on a dialysis machine after powering on the dialysis machine, wherein the at least one integrity test is selected from the group consisting of a battery test, a dialysate conductivity test, and a dialysate temperature test. The method also includes presenting, on a display of the dialysis machine, a first set of instructions for priming the dialysis machine after completing the at least one integrity test.

Automatic priming and scheduling for dialysis systems

A dialysis system, comprising: a dialysis machine; a voice recognition component configured to identify a voice command in audio information received by a microphone of the dialysis system; an authentication component configured to determine a source of the voice command; and a processor configured to perform a function determined based on the voice command.

Remote control of multiple medical devices

A leak may be detected in a heat exchanger of a hemodialysis device. A drain valve is opened by the controller, and then closed by the controller after a pre-selected time period. An initial pressure is determined in the spent dialysate circuit and stored in the memory. A system pressure is determined at periodic time intervals and compared to a pre-determined maximum pressure. The controller then determines whether the heat exchanger has a leak, in that in response to the system pressure exceeding a predetermined maximum pressure, a command is generated to execute an event including suspending a disinfectant operation with a disinfecting agent, and in response to the initial pressure subtracted from the system pressure being greater than a predetermined minimum pressure differential, a command is generated to execute an event including suspending the cleanse operation with the disinfecting agent.

A networked dialysis system includes a dialysis machine, a user interface, and a device that is located remotely from the dialysis machine and that exchanges information with the dialysis machine via a networked communications link. A digital data processor, which is coupled to the dialysis machine and to the remote device, facilitates execution of services on one or more remote digital data processing systems. The digital data processor is coupled to the remote device via the networked communications link and is coupled to the dialysis machine via a second communications link.

Remote interfacing with a networked dialysis system

In general, a dialysis device includes a first processing device for monitoring dialysis functions of the dialysis device, a second processing device, a display device, and memory. The memory is configured to store instructions that, when executed, cause the dialysis device to provide, on the display device, a first display region and a second display region, where the first display region is associated with the first processing device and the second display region is associated with the second processing device. At least a portion of the first display region cannot be obscured by the second display region.

User interfaces for dialysis devices

A system for controlling the position of a diaphragm in a diaphragm-containing pressure pod, is provided. The system can include a peristaltic pump, a pressure pod having a flow-through fluid side and a gas side that are separated by a diaphragm, and a pressure sensor operatively connected to the gas side. The pressure sensor is configured to sense pulses of pressure resulting from movement of the diaphragm and caused by the action of the peristaltic pump. A gas source and a valve can be in fluid communication with the gas side of the pressure pod and can be configured to provide gas to, or vent gas from, the gas side. A controller receives pressure signals from the pressure sensor and controls the valve in response, and in so doing, controls the position of the diaphragm. Methods for positioning the diaphragm are also included.
