A method and system for capturing data and verifying the data accuracy, includes a structured document having defined regions dealing with different categories. Dictionaries specific to the categories are included to check the accuracy. of words and phrases in the various regions. Points are allocated to the entered data to facilitate subsequent decision making, and a facility is provided to maximize the accumulation of points by visually indicating regions that could potentially be filled in to increase points most effectively. Preferably data is entered orally by a user into a computer system, and transcribed using speech-recognition software. The user is prompted for data entry, and the prompting mechanism may follow a predefined pattern and speed, or be adjustable by the user, or be adjusted by the computer by monitoring past user behavior.

Data capture and verification system

The present invention detects how much air is inhaled through the inhaler with what time course (including such derived measurements as how much volume is inspired within the bounds of a given flow range) as well as certain events such as the triggering of the release of aerosol. The system can be set up to compare the resultant time course to either (a) a standard target envelope (e.g., one or more of flow, volume, and time) for that patient programmed into the intelligent inhalation device by a healthcare professional. Based on the comparison, the success or failure of effective inhaler actuation and aerosol inspiration can be signaled to the patient (e.g., visually or through sound) and may be recorded with a time and date stamp for later decoding and evaluation of the invention, the device would also possess the ability to signal the patient to continue post-inspiratory breath holding for use in interpreting the success of medication delivery.

Intelligent inhaler providing feedback to both patient and medical

An apparatus for interactive training of a patient in the use of an aerosol inhaler includes a feedback display based upon air flow versus volume data in order to train patients to use a proper sequence of inhalation steps to insure maximum delivery of an aerosol pharmaceutical to target sites in the lungs. Flow and volume data are displayed to provide the patient and physician with a real-time, interactive representation of the inhalation process. Visual feedback to the patient includes a portrayal of the lungs which may be either three dimensional or an outline form in addition to or instead of an X-Y display. An important element of visual feedback is the portrayal of the distribution of representative droplets of aerosol medication in various stages of inhalation and breath holding. Thus, the patient is provided with meaningful feedback representative of the actual distribution of aerosol medication. The real-time representation of the delivery of medication to the lungs enables a patient to derive a maximum therapeutic benefit from pharmaceuticals which are administered through inhalation. The improved feedback also enables a patient to learn proper inhalation techniques which enable therapeutic agents to be such as aerosol glucocorticoids to be delivered directly to target sites in the lungs thereby bypassing the digestive system and obviating adverse side effects. The improved visual feedback to the patient representing the actual distribution of inhaled aerosol in the lungs conveys a conceptual understanding of the proper inhalation process and greatly increases the likelihood that a patient will learn and retain the correct inhalation technique.
