Control Systems and Methods for Blood or Fluid Handling Medical Devices
First Claim
1. A system for controlling delivery of purified water to a hemodialysis apparatus comprising:
- a therapy controller of the hemodialysis apparatus configured to communicate with a controller of a water purification device;
a user interface controller of the hemodialysis apparatus configured to communicate with the therapy controller, and configured to send data to and receive data from a user interface;
the therapy controller configured to receive information from the water purification device controller related to one or more of the following;
whether the water purification device is ready to provide purified water;
an amount of purified water stored in the water purification device;
a temperature of stored purified water in the water purification device;
a conductivity or resistivity of purified water in the water purification device;
whether one or more components of the water purification device is due for service or replacement; and
whether the water purification device has issued one or more error flags;
wherein the therapy controller is configured to perform one or more of the following tasks in response to information received from the water purification device;
command the user interface controller to issue a message to the user interface;
receive input from the user interface controller in response to input from the user interface; and
suspend or terminate a therapy of the hemodialysis apparatus, or prevent a future therapy of the hemodialysis apparatus until a repair or maintenance procedure has been performed on the water purification device.

Abstract
A processor of a medical device configured to communicate with a remote server can be programmed to protect the medical device from exposure to unauthorized or malicious software. A system or method to implement this form of protection can include, for example, at least one processor on the medical device, a control software module that controls the operation of the medical device and is executable on the processor, a data management module that manages data flow to and from the control software module from sources external to the medical device, and an agent module that has access to a limited number of designated memory locations in the medical device. In addition, a hemodialysis apparatus can be configured to operate in conjunction with an apparatus for providing purified water from a source such as a municipal water supply or a well. A system for controlling delivery of purified water to the hemodialysis apparatus can comprise a therapy controller of the hemodialysis apparatus configured to communicate with a controller of a water purification device, and a user interface controller of the hemodialysis apparatus configured to communicate with the therapy controller, and to send data to and receive data from a user interface.
