"Dialysis Treatment Simulation Systems and Methods" in Patent Application Approval Process

August 15, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- A patent application by the inventor Ryder, Patricia A. (West Roxbury, MA), filed on January 18, 2013, was made available online on July 31, 2014, according to news reporting originating from Washington, D.C., by NewsRx correspondents (see also Fresenius Medical Care Holdings, Inc.).

This patent application is assigned to Fresenius Medical Care Holdings, Inc.

The following quote was obtained by the news editors from the background information supplied by the inventors: "Dialysis machines are well known for treating medical conditions related to renal failure, where a person's kidneys inadequately filter toxins and waste products from the blood. One type of a dialysis procedure is referred to as hemodialysis, wherein blood is removed from the patient and output to a dialyzer associated with a hemodialysis machine. The patient's blood circulates along one side of a semipermeable synthetic membrane in the dialyzer, referred to as an extracorporeal circuit (ECC). A dialysate solution is provided by a dialysate delivery system, and flows between the dialysate delivery system and the hemodialysis machine along the opposite side of the membrane, referred to as a dialysate circuit, to remove waste, toxins, and other undesirable products from the blood. Other dialysis procedures involve a peritoneal treatment, which employs a natural membrane from a patient's own body.

"A dialysis machine typically includes various meters, sensors, and other event detection and monitoring systems positioned along the ECC and the dialysate circuit to monitor an array of safety-critical parameters and to detect abnormal events occurring prior to or during a dialysis procedure. The parameters are typically displayed as text, graphics, and the like at a control panel monitor, touchscreen, or other display. A dialysis machine operator monitors the display during a treatment for abnormal events, and can make any necessary adjustments if an abnormal event occurs. Inadequately trained hemodialysis machine operators can cause patient injury or death during a treatment."

In addition to the background information obtained for this patent application, NewsRx journalists also obtained the inventor's summary information for this patent application: "In accordance with one aspect, provided is a medical treatment simulation system comprising a treatment simulator, a dialysis treatment simulation system, comprising a treatment simulator, a computing module, and a user interface. The treatment simulator simulates an event notification related to an interaction between a dialysis treatment machine and a patient. The computing module generates a request for a user action in response to the simulated event notification. The user interface outputs the simulated event notification and the request for the user action to an output device and provides a received user response to the computing module.

"In an embodiment, the computing module generates a multiple choice question and one or more possible answers to the multiple choice question, and wherein the received user response includes a user-selected answer of the one of the computer module-generated possible answers.

"In an embodiment, the computing module generates a question and a blank field, and wherein the user action includes entering a response to the question in the blank field.

"In an embodiment, the computing module processes a response to the request for the user action input to the user interface by an operator.

"In an embodiment, the treatment simulator generates simulation data related to the interaction between the dialysis treatment machine and the patient, the simulation data simulating treatment parameters related to the interaction between the dialysis treatment machine and the patient.

"In an embodiment, the event notification is displayed in response to a simulated treatment parameter exceeding a treatment parameter threshold.

"In an embodiment, the event notification simulates at least one of an alarm notification, a warning notification, or a status advisory notification.

"In an embodiment, the event notification simulates an abnormal event related to a dialysis treatment.

"In an embodiment, the user interface provides the event notification with a graphical element to a visual display.

"In an embodiment, the graphical element includes at least one of a window, a menu, a radio button, a check box, a status box, an icon, or a display field.

"In an embodiment, the dialysis treatment simulation system further comprises a results processor that determines from the received user response a competence level of a user with respect to operating the dialysis treatment machine.

"In an embodiment, the output device is at least one device selected from a computer display, a tablet computer, and a mobile device.

"In an embodiment, the dialysis treatment simulation system further comprises a timer that determines whether a user responds to a presented question within a predetermined period of time.

"In an embodiment, the system is operated by at least one of a healthcare practitioner, a dialysis patient, or a technical service personnel for training on the operation of the dialysis treatment machine.

"In accordance with an aspect, provided is a computer-implemented method for performing a dialysis treatment simulation. An event notification is generated that simulates an event notification related to an interaction between a dialysis treatment machine and a patient. A request is generated for a user action in response to the simulated event notification. The simulated event notification and the request for the user action are output to an output device. A received user response to the request for the user action is processed.

"In an embodiment, outputting the request includes displaying, at a treatment display, a menu of options for a user to select from.

"In an embodiment, at least one of the menu options corresponds to a correct action for addressing the displayed simulated event notification.

"In an embodiment, generating an event notification comprises executing computer code that simulates the event notification.

"In accordance with another aspect, provided is a method of simulation for training a trainee of a dialysis treatment machine. An event notification related to a simulated dialysis treatment is displayed at a display. A response activation is performed. A question regarding the displayed event notification is displayed at a display. A response to the question is processed.

"In an embodiment, the response activation includes selecting a button at the display.

"In an embodiment, displaying the question includes displaying, at the display, a menu of options for a user to select from.

"In an embodiment, method further comprises generating a multiple choice question and one or more possible answers to the multiple choice question; and selecting an answer of the one or more possible answers as the response.

"In an embodiment, the method further comprises generating a question and a blank field; and entering the response at the blank field.
