Abstract

An external medical device includes monitoring circuitry configured to monitor a cardiac condition of a patient using the external medical device; and a controller configured to: receive at least one of patient input and non-patient user input of a patient's ability; determine a patient interaction mode of the external medical device based on the at least one of the patient input and the non-patient user input; and adapt the patient interaction mode of the external medical device over time based on the at least one of the patient input and the non-patient user input.

First claim

What is claimed is:

1. An external medical device comprising:
at least one ECG electrode and associated monitoring circuitry configured to be worn on a body of a patient to monitor for a cardiac arrhythmia condition of the patient requiring treatment using the external medical device;
at least one therapy electrode configured to be worn on the body of the patient to deliver a treatment to the patient upon detection of the cardiac arrhythmia condition requiring treatment;
a touch screen comprising one or more visual features or functions;
at least one sensor configured to detect at least one of patient activity and/or environmental input; and
a controller in communication with the at least one ECG electrode, the at least one therapy electrode, the touch screen, and the at least one sensor, the controller configured to:
receive, during an initial interaction with the touch screen, at least one of a patient input and/or a non-patient user input responsive to a predetermined test of at least one of the patient's ability, function, and/or skill;
determine an initial patient interaction mode of the touch screen of the external medical device comprising a requested response action to be provided in response to one or more alarms or alerts issued by the external medical device based on the at least one of the patient's ability, function, and/or skill;
receive a plurality of patient inputs over time to the touch screen; and
adapt the initial patient interaction mode of the touch screen of the external medical device over time by changing the one or more visual features or functions of the touch screen based on the received plurality of patient inputs to the touch screen and the at least one of patient activity and/or environmental input,
wherein the adapting further comprises changing the requested response action based on the plurality of patient inputs over time.

2. The external medical device of claim 1 , wherein the controller is configured to cause the external medical device to enter the initial patient interaction mode, and wherein the initial patient interaction mode is selected based on a technology comfort level of the patient as determined from the at least one of the patient input and/or the non-patient user input.

3. The external medical device of claim 1 , wherein at least one of the initial patient interaction mode and/or the adapted patient interaction mode is selected from a) a first technology comfort mode, b) a second technology comfort mode, and/or c) a custom technology comfort mode, wherein each of the first mode, the second mode and the custom mode are selected from a plurality of modes associated with a technology comfort level of the patient.

4. The external medical device of claim 3 , wherein the first technology comfort mode is characterized by having predominantly more textual elements on the touch screen of the external medical device than the second technology comfort mode.

5. The external medical device of claim 3 , wherein the second technology comfort mode is characterized by the one or more visual output features or functions having predominantly more image, animation, or video based elements on the touch screen of the external medical device than the first technology comfort mode.

6. The external medical device of claim 3 , wherein the custom technology comfort mode is characterized by further allowing the patient or a non-patient user to configure the touch screen by adjusting or customizing the one or more visual output features or functions of the touch screen.

7. The external medical device of claim 1 , wherein determining or adapting the initial patient interaction mode by changing the one or more visual features or functions of the touch screen comprises at least one of the following: a) selection of one or more visual elements for an interface of the touch screen, b) an arrangement of the one or more visual elements on the interface, c) an output display color of the one or more visual elements, d) an image or font display size of the one or more visual elements, and/or e) a display contrast of the one or more visual elements for the interface.

8. The external medical device of claim 1 , wherein the controller is further configured to adapt the initial patient interaction mode by setting or changing one or more of the following features or functions of the external medical device: a) output features or functions of the external medical device, b) audio output features or functions of the external medical device, and/or d) tactile output features or functions of the external medical device.

9. The external medical device of claim 8 , wherein the output features or functions of the external medical device comprise at least one of the following: a) an order or a sequence of one or more alarms, alerts, or instructions issued by the external medical device, b) a type of the one or more alarms, alerts, or instructions issued by the external medical device, c) a frequency of occurrence of one or more alarms, alerts, or instructions issued by the external medical device, and/or d) an escalation pattern of the one or more alarms, alerts, or instructions issued by the external medical device.

10. The external medical device of claim 8 , wherein the audio output features of the external medical device comprise at least one of the following: a) selection of one or more audio output elements including one or more of a tone alarm or alert, a gong alarm or alert, a siren alarm or alert, or verbal messages, b) an order or sequence of the one or more audio output elements provided by the external medical device, c) an audio output volume of the one or more audio output elements, d) a tonal frequency of the one or more audio output elements, and/or e) an escalation pattern of the one or more audio output elements.

11. The external medical device of claim 8 , wherein the tactile output features of the external medical device comprise at least one of the following: a) selection of one or more tactile mechanisms including one or more of a continuous vibration, a pulsed vibration, or a mixed vibration, b) an order or sequence of the one or more tactile mechanisms provided by the external medical device, c) an intensity of the one or more tactile mechanisms, d) a frequency of vibration of the one or more tactile mechanisms, and/or e) an escalation pattern of the one or more tactile mechanisms.

12. The external medical device of claim 1 , wherein the controller is configured to provide the predetermined test comprising a series of prompts during the initial interaction, and wherein the at least one of the patient input and/or the non-patient user input comprises responses from the patient and/or a non-patient user to the series of prompts during the initial interaction.

13. The external medical device of claim 1 , wherein the controller is configured to:
receive a request from at least one of the patient or a non-patient user to change at least one of the initial patient interaction mode and/or the adapted patient interaction mode, and
change the at least one of the initial patient interaction mode and/or the adapted patient interaction mode based on the received request.

14. The external medical device of claim 1 , wherein the controller is configured to determine the initial patient interaction mode as a custom patient interaction mode wherein the custom interaction mode is characterized by further allowing the patient or the non-patient user to configure the touch screen by adjusting or customizing the one or more visual output features or functions of the touch screen.
