Abstract
The present disclosure is directed to methods and systems that analyze one or more analytes in a fluid, such as breath, emitted from a user. The methods and systems can detect one or more analytes in the breath of a user to provide alerts in response to discrepancies in medications taken by a user, verify one or more medications taken by a user, manage a medication regime of a user, and various other functions disclosed herein.
Core Innovation
The invention provides a method and system for adjusting dosage of an agent using information generated from exhaled breath detected by at least one sensor positioned in an exhalation path of a user. The sensor is configured to detect analytes in exhaled breath, and the generated information is processed to determine a concentration of a first analyte and an absence of a second analyte. The method determines an adjustment to a delivery device configured to deliver the agent to the user based, at least in part, on the concentration of the first analyte.
The exhaled-breath information used for the adjustment is generated from multiple discrete measurements during multiple discrete sessions of the at least one sensor detecting the analytes in the exhaled breath of the user. The method provides one or more visual instructions on a display that instruct the user on how to operate the delivery device to implement the determined adjustment, and a control system executes machine-readable instructions to receive, process, determine the adjustment, and provide the visual instructions.
The invention further integrates medication verification and remote communication workflows with the breath-derived determinations. The method determines one or more medications taken by the user by accessing electronic medical records at a remote system, determines a discrepancy in the one or more medications taken by the user based on the absence of the second analyte and one or more analytes associated with the one or more medications, and causes a transmission of a first message to the remote system based on the determination of the discrepancy.
The method receives a confirmation receipt for the first message and verifies authenticity of the confirmation receipt based, at least in part, on a key transmitted with the confirmation receipt, thereby tying dosage adjustment and medication discrepancy reporting to remote-system acknowledgement and key-based authenticity verification.
Claims Coverage
The consolidated content includes two independent claims, a method claim and a system claim. Both claims share breath sensing in an exhalation path, processing to determine a first analyte concentration and a second-analyte absence, multiple discrete measurements across multiple discrete sessions, adjustment of a delivery device, and visual instructions. Both also include remote electronic medical records, discrepancy messaging, and confirmation-receipt authenticity verification using a key.
Exhalation-path exhaled-breath sensing for analyte presence and concentration
Receiving, from at least one sensor positioned in an exhalation path of a user and configured to detect analytes in exhaled breath of the user, information generated based on the exhaled breath of the user; processing the information to determine a concentration of a first analyte and an absence of a second analyte in the exhaled breath.
Dose adjustment based on multi-session breath measurements
Determining an adjustment to a delivery device configured to deliver the agent to the user based, at least in part, on the concentration of the first analyte, wherein the information generated based on the exhaled breath of the user is from multiple discrete measurements during multiple discrete sessions of the at least one sensor detecting the analytes in the exhaled breath of the user.
Visual instructions to operate the delivery device
Providing one or more visual instructions on a display that instruct the user on how to operate the delivery device to implement the determined adjustment.
Medication determination from remote electronic medical records and discrepancy messaging
Determining one or more medications taken by the user by accessing electronic medical records at a remote system associated with the user listing the one or more medications; determining a discrepancy in the one or more medications taken by the user based on the absence of the second analyte and one or more analytes associated with the one or more medications; causing a transmission of a first message to the remote system based on the determination of the discrepancy in the one or more medications; and receiving, from the remote system, a confirmation receipt for the first message.
Key-based authenticity verification of confirmation receipt
Verifying authenticity of the confirmation receipt based, at least in part, on a key transmitted with the confirmation receipt.
System execution with sensor, display, memory, and control system
At least one sensor positioned in an exhalation path of a user, the at least one sensor configured to detect analytes in exhaled breath of the user; a display configured to present images to the user; memory containing machine-readable instructions; and a control system having one or more processors in communication with the memory, the control system configured to execute the machine-readable instructions to receive, from the at least one sensor, information generated based on the exhaled breath of the user; process the information to determine a concentration of a first analyte and an absence of a second analyte in the exhaled breath; determine an adjustment to a delivery device configured to deliver the agent to the user based, at least in part, on the concentration of the first analyte; provide one or more visual instructions on a display that instruct the user on how to operate the delivery device to implement the determined adjustment; determine one or more medications taken by the user by accessing electronic medical records at a remote system associated with the user listing the one or more medications; determine a discrepancy in the one or more medications taken by the user based on the absence of the second analyte and one or more analytes associated with the one or more medications; causing a transmission of a first message to the remote system based on the determination of the discrepancy in the one or more medications; receiving, from the remote system, confirmation of receipt of the first message; and verifying authenticity of the confirmation based, at least in part, on a key transmitted with the confirmation.
Across the independent method and system claims, the coverage centers on breath-derived determination of a first analyte concentration and a second-analyte absence using multiple discrete measurements across multiple discrete sessions to drive dosage adjustment for a delivery device, while also determining medication information from remote electronic medical records to identify discrepancies and transmit messages to a remote system with confirmation receipt authenticity verification using a key.
