Abstract
A system and method to collect feedback data from a patient wearing an interface such as a mask when using a respiratory pressure therapy device such as a CPAP device. The system includes a storage device including a facial image of the patient. An interface in communication with the respiratory pressure therapy device collect operational data from when the patient uses the interface. A patient interface collects subjective patient input data from the patient in relation to the patient interface. An analysis module correlates a characteristic of the interface with the facial image data, operational data and subjective patient input data.
Core Innovation
The invention provides a mobile device workflow for collecting feedback about an interface used with a respiratory therapy device by capturing a facial image while the user wears the interface. The mobile device overlays a location grid in the shape of the interface over the facial image, where the grid includes a plurality of areas defined by lines representing contact between the interface and the user’s face.
The device provides a graphical indicator that accepts a user selection for discomfort for contact or for a leak in the interface. An input interface is generated on the display to collect user input data relating to the interface for the respiratory therapy device, and the collected user input data relating to the interface and the facial image data is stored in a computer readable medium.
The documented approach supports collecting feedback information through an on-display graphical interface, including user selection of grid areas as to discomfort for contact or to a leak in the interface. Additional feedback information collection is supported through on-display input interfaces that request user input data, including comfort questionnaire data and sleep-related data, and through optional communication to an external system in which stored facial data and user input data can be transmitted.
Claims Coverage
The independent claims are directed to a mobile device, a non-transitory computer readable medium, and a system for collecting feedback data. The core inventive concept centers on facial image capture while wearing a respiratory therapy interface, overlaying an interface-shaped contact/leak location grid, collecting user selections tied to discomfort or leaks, and generating and storing user input data associated with the facial image. Across the independent claims, there are three primary inventive features.
Capturing a facial image while wearing a respiratory therapy interface
Capture a facial image of a user via a camera, wherein the user wears an interface for a respiratory therapy device when the user uses the respiratory therapy device.
Overlaying an interface-shaped location grid representing contact areas
Overlay a location grid in the shape of the interface for the respiratory therapy device over a facial image on the display, the location grid including a plurality of areas each defined by lines in the grid representing contact between the interface for the respiratory therapy device and the face of the user.
Collecting graphical selections for discomfort or leaks on the grid
Provide a graphical indicator for accepting a user selection in at least one of the plurality of areas of the grid as to discomfort for contact or to a leak in the interface.
Generating an input interface to collect and store interface feedback tied to facial image data
Generate an input interface on a display to collect user input data from the user relating to the interface for the respiratory therapy device; store user input data relating to the interface and the facial image data in the computer readable medium or a storage device.
The independent claims consistently cover capturing facial image data while the user wears a respiratory therapy interface, overlaying a grid shaped to represent contact areas between the interface and the face, enabling user selection on grid areas for discomfort/contact or leaks, and generating an on-display input interface to collect and store the resulting user input data together with the facial image data.
