Continua Compliance: Explanation

Continua Compliance: Semester Plan

 Planned for difficulty  2 weeks Fall 2013  8 weeks Spring 2014  Pushing into time allocated for debug  3 additional three weeks  Total ~13 weeks for Continua Compliance

Continua Compliance: Methods Attempted  RFCOMM : Redesign Bluetooth  Antidote: Continua compliant service  Oximeter HDP tutorial  HDPy repository  AND Blood pressure pump to Linux computer  Contact HDPy developers  Linux to Linux spoof oximeter data example  Linux to Linux spoof blood pressure data

Continua Compliance: Demo

Progress: Design Specification 1.External Power Supply 2.Enclosure for device 3.Interface with blood pressure pump (BPP) 4.System uses a touch screen interface for user control 5.Continua compliant 6.Android Application with user interface

Android Application Android HDP Application Android application that supports the Health Device Protocol standard with Bluetooth capability. Likely has error in the stack

 Wrap Continua Communication in C programming wrapper  Establish auto-pairing between manager and agent  Create Continua Compliant Android sink Related Future Work

 Source code  Drawings and documentation  User’s manual for prototype blood pressure machine  Documentation for FDA Documentation

 Submission of a PMN (510k)  Must show substantial equivalence to a chosen predicate device.  A&D UA-767PBT  A&D UA-767PBT-C  Equivalence is shown through:  Indication Statements  Intended Use  Technological Characteristics  Descriptive Characteristics FDA Documentation

1.Accurate data transmission 2.Function properly with extended runtime 3.User setup and run without instructions 4.Behavior with various data interruption 5.Interface to Continua Devices Plan: Testing

Test name: Accurate data transmission Independent variables: Blood pressure pump Dependent variables: Data readings (systolic pressure, diastolic pressure, heart rate) Controls: Environment of testing, person who’s blood pressure is being measured Plan: Testing

Test name: Function properly with extended runtime Independent variables: Time elapsed Dependent variables: Device functionality: Able to take and view blood pressure reading Controls: Testing environment Plan: Testing

Test name: User setup and run without instructions Independent variables: User selected Dependent variables: Time for user to view their blood pressure Controls: Withhold instructions, method of seeking feedback, testing environment Plan: Testing

Test name: Behavior with various data interruption Independent variables: Method of interruption Dependent variables: After connect is reestablished, if data passed continues to be passed without an error Controls: Test environment, trials per independent variable Plan: Testing

Test name: Interface to Continua Devices Independent variables: Device used as agent Dependent variables: If correct data is passed from agent to manager Controls: Test environment, managing device Plan: Testing
