Abstract
A system for providing continuous positive air pressure therapy is provided. The system includes a patient interface, a flow generator, a sensor, and a computing device. Wireless transceivers allow wireless communication between the computing device and the flow generator and/or patient interface. Sensor data is communicated to the computing device and a leak determination is made by the computing device based on the sensor data. If a leak is detected, then troubleshooting options for correcting the leak are displayed to the patient on a display of the computing device. The troubleshooting options may be selected based on the sensed data, the type of patient interface, the type of flow generator, or characteristics of the patient using the device.
Core Innovation
The invention relates to a CPAP system in which a computing device electronically communicates with a respiratory therapy device configured to generate a supply of breathable gas delivered to a patient via a patient interface. At least one sensor measures a physical quantity while the breathable gas is supplied to the patient, and the computing device processes sensor data to obtain a leak determination. When a leak is detected, the system outputs to a display device a display screen that includes instructions for at least a first troubleshooting option selected to correct the leak and commands the respiratory therapy device to hold the pressure at a held pressure level different from the target pressure level.
After the command to hold pressure is communicated, the system processes second sensor data based on another instance of the measured physical quantity and obtains another leak determination. If the another leak determination indicates there is no leak, the system communicates a further command to cause the pressure of the supply of breathable gas to resume increasing toward the target pressure level. The workflow ties leak determination to stopping pressure increase, presenting selected troubleshooting options, and then rechecking to decide whether pressure increase should resume.
The instructions can be configured to select the first troubleshooting option based on the type of respiratory therapy device and/or patient interface used to deliver breathable gas to the patient’s airway. The system can also transmit a message based on first sensor data to an external computing device to obtain a leak determination, and it can obtain a third leak determination after a prior leak determination. Upon detecting a leak at the third determination, the system outputs a second troubleshooting option selected to correct the leak, where the first and second troubleshooting options are among multiple troubleshooting options and differ from each other.
Claims Coverage
The partial document identifies three independent claims covering a CPAP system, a non-transitory computer readable storage medium, and a computing device. Across these claims, there are seven inventive features that implement leak determination from sensor data, conditional pressure control by holding pressure at a different held pressure level, and presentation of selected troubleshooting instructions when a leak is detected.
Sensor-based leak determination during CPAP delivery with conditional pressure hold
A respiratory therapy device generates a supply of breathable gas delivered to a patient via a patient interface engaging at least one airway, at least one sensor measures a physical quantity while the breathable gas is supplied, sensor data is processed to obtain a leak determination, and upon detection of a leak the system communicates a command to hold the pressure at a held pressure level different from the target pressure level.
Display of selected troubleshooting option when a leak is detected
Based on detection of a leak by the leak determination, the system outputs to a display device associated with the computing device a display screen that includes instructions for at least a first troubleshooting option selected to correct the leak.
Recheck using subsequent sensor data and resume increasing toward target pressure when no leak
After the command to hold the pressure at the held pressure level, the system processes second sensor data based on another instance of the measured physical quantity, obtains another leak determination, and when the another leak determination indicates there is no leak the system communicates a further command to cause the pressure of the supply of breathable gas to resume increasing towards the target pressure level.
External computing device messaging to obtain leak determination
Transmitting a message based on first sensor data to an external computing device to obtain a leak determination.
Troubleshooting option selection based on respiratory therapy device and/or patient interface type
Selecting the first troubleshooting option based on a specific type of respiratory therapy device and/or patient interface used to deliver the supply of breathable gas to a patient’s airway.
Held pressure level defined based on timing of leak detection
Setting the held pressure level to a pressure value determined based on the time when a leak was detected.
Sequenced multi-determination troubleshooting with differing troubleshooting options
Obtaining a third leak determination after a prior leak determination, and based on detection of a leak at the third determination, outputting to a display device a second troubleshooting option selected to correct the leak, where the first and second troubleshooting options are among multiple troubleshooting options and differ from each other.
Overall, the claim coverage is centered on electronically communicating commands with a CPAP respiratory therapy device, measuring physical quantity via sensors to obtain leak determinations, holding pressure at a different held pressure level when leaks are detected while displaying selected troubleshooting instructions, and then re-evaluating with subsequent sensor data to resume pressure increase when no leak is determined. Dependent refinements in the partial content further ground the leak workflow by specifying measured quantity as pressure or flow data, providing optional external-computing-device leak determination, tying troubleshooting selection to device/interface type, defining held pressure level based on the time of leak detection, and enabling a multi-step recheck sequence with differing troubleshooting options.
