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 hemodialysis system including one or more ultraviolet chambers is disclosed. The hemodialysis system including a dialyzer arranged and configured to filter a patient's blood, a hemodialysis machine arranged and configured to pump, move, or the like dialysate through the dialyzer, the hemodialysis machine including an outlet valve and an outlet fluid flow path to pump or move dialysate from the hemodialysis machine to the dialyzer, and an inlet valve and an inlet fluid flow path to pump or receive dialysate from the dialyzer, and one or more ultraviolet chambers arranged and configured to kill bacteria, viruses, or a combination thereof. Thus arranged, by incorporating one or more ultraviolet chambers in strategic areas of the system, the ultraviolet chambers may eliminate, or at least greatly reduce, the possibility of cross-contamination in, for example, the dialysate, and thus eliminate the need for disinfecting the system between treatments.

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.

Method of detecting a leak in a heat exchanger of a hemodialysis machine

A medical device, such as a peritoneal dialysis machine, includes a sensor for sensing motion and/or user proximity in the vicinity of the medical device for the purpose of automated dimming a display of the medical device. In the event of a lack of user-activity on a machine interface and a lack of movement detected by the proximity sensor, the machine display is automatically dimmed to minimize power-consumption and provide an enhanced medical device for night therapies in a home or clinic environment. The machine display may be dimmed in the event of an alarm-free machine condition, where no machine activity is detected and/or where no movement is detected by the sensor over one or more time periods. When machine activity is detected, when movement is detected by the proximity sensor, and/or in the event of a machine alarm or warning, the machine display may be automatically undimmed.

This disclosure relates to remote control of home dialysis machines, for example, using a network connected system including a network device. In an aspect, a dialysis system includes a network device, a dialysis machine configured to connect to the network device over a network, and a mobile device configured to connect to the network device over the network. The network device is configured for receiving, from the mobile device, through the network, a request to access the dialysis machine, receiving an authorization for the mobile device to access the dialysis machine, and after receiving the authorization, transferring, through the network, between the dialysis machine and the mobile device, information pertaining to one or more of an operation of the dialysis machine or the mobile device.

Remote control of dialysis machines

A dialysis machine useful in hemodialysis can process or treat a reverse osmosis water flow received through the machine to prepare a dialysate. The machine can include an additive source to introduce an additive, such as bicarbonate, to the reverse osmosis water flow. The machine can include a sensor in fluid communication with the additive introduction point that can measure the conductivity or similar characteristic of the solution. During a first time period when additive is actively introduced to the reverse osmosis water flow, the sensor can measure a relatively high conductivity value. During a second time period when additive is not introduced to the reverse osmosis water flow, the sensor can measure a relatively low conductivity value. The dialysis machine can include a controller that processes these measurements to assist control and operation of the machine.
